What are the door hardware fittings?

Abstract: Door hardware fittings generally refer to door and window hardware fittings. What are the hardware fittings for doors and windows? The development of window hardware fittings is closely related to the evolution of window type and window opening mode. The motivation of this evolution is people's understanding of the function of windows and their thinking about the convenience of using windows. What is the main function of window hardware fittings? What is the function of hardware fittings for doors and windows?

Classification of hardware fittings for doors and windows

Sliding window hardware parts

The guide rail of aluminum alloy or plastic steel sliding window is directly formed on the window frame profile, and the pulley system is fixed at the bottom of the window sash. Whether the sliding window is free depends not only on the quality of pulley system, but also on the flatness and machining accuracy of profile and the installation accuracy of window frame. The abrasion of dust on the track and pulley will also affect the opening and closing function of the sliding window. The lock of sliding window is usually a latch lock, which will fail because of low installation accuracy and dust accumulation. The handle of the sliding window is generally replaced by the switch part of the latch lock, but there are also high-grade sliding windows that make the sash profile into an arc to play the role of handle.

Hardware fittings for casement windows

One of the basic accessories of casement window is hinge. Due to the one-way opening nature of the hinge, the hinge is always installed in the opening direction, that is, the inner window hinge is installed indoors and the outer window hinge is installed outdoors.

In order not to let the hinge affect the sealing of the window, the hinge of metal window is usually welded outside the window profile. The lock for opening the window is a rotary lock, and the handle is usually combined with the phase lock. The lock of an ordinary inner window can be a simple bolt. The disadvantage of the latch is that it does not have the pressing function of the rotary latch.

The handle of the inner window is independent and has nothing to do with other parts. The stopper is an indispensable part of the outer window, which is used to prevent the window sash from colliding when it is blown by the wind. However, the firmness of the fixed plane formed by the two hinges and the stopper at three points is limited, and the stopper with better quality is copper rust-proof.

Tilting and Inverting Window Hardware Parts

The concept of inward inclined casement window is formally a window that can be hung downward and opened horizontally. But this is far more than a special way to open a window. In fact, it is a synthesis of various window control functions.

First of all, when the window leans inward, the purpose is to take a breath. The top scissor connector acts as a brake. When the interior is flat, the top scissor connector is a hinge. The bottom hinge is also an inward axis. On the one hand, the purpose of opening the window horizontally is to clearly observe the scenery outside the window, and more importantly, to facilitate the cleaning of the glass. Window design does not consider clean glass, which is also the reason why there are few clean and bright windows in middle and low-grade houses in China.

It can be said that the introversion casement window is a comprehensive satisfaction for people. The hardware of inclined casement window includes top shear connector, upper corner connector, lock, handle, connecting rod, multi-point lock, lower corner connector and bottom shaft, as well as bottom hinge and bottom shaft. This kind of hardware is suitable for wood, aluminum alloy and plastic steel windows.

How to fix the connecting rod on the window sash? There are two solutions. Firstly, two sets of connecting rods are designed, one for fixing and the other for interlocking locking points. Secondly, the chute is designed in advance on the window frame profile. The second scheme is superior to the first scheme in terms of service life and maintenance-free.

Glass curtain wall hardware parts

The combination of glass curtain wall and window is a difficult problem. The advanced curtain wall system in the world can make the inclined casement window into a glass-like curtain wall unit, and realize the air tightness, water tightness and wind pressure resistance of the curtain wall as a whole. The technical level and cost of doing this are very high. At present, few domestic companies can reach this level.

Because the load-bearing structure of glass curtain wall is generally inside, it is the easiest window opening scheme to open the window outside. However, if hinges are used, the exposed hinges will destroy the integrity of the glass curtain wall, so there are four-bar fittings. Four-bar linkage is a substitute for hinge, and the purpose of window opening is achieved by using the principle that the area of quadrilateral can be changed under the condition of constant side length.

The four-bar linkage is fixed on the side of the sash and the window frame. When closing the window, the four links are completely hidden in the window frame, which fundamentally solves the problem of exposed hinges. The only feature is the phenomenon determined by the working principle of the four-bar linkage, that is, when the window sash is opened, the center of gravity of the window sash will have an obvious settlement. This arrangement can well prevent the wind from closing the window sash, but it brings a lot of inconvenience to the installation and use of the window opener. If the window is large, the four-bar linkage will bear the weight of the window sash for a long time, which will lead to a certain decline, and then the window sash will not close well.

Multi-point locks are used to increase the wind pressure intensity of windows. The window sash is connected with a plurality of cylindrical locking points through connecting rods, and the locking points slide into the lock body fixed on the window frame under the operation of the rotating handle. The four sides of the window can be locked by one, two or more locking points through corner connectors. Multi-point lock has completely changed the traditional window locking system. This connecting rod locking scheme is also to improve the anti-theft level of the door.

Fanfanchuang hardware parts

In ordinary casement windows, it is difficult to seal the window because half of the sash is open inside and the other half is open outside. To achieve the same sealing effect as a simple inner window or an outer window, the cost of turning the window will be higher. The hardware fittings of ordinary window-turning are mainly two rotating shafts, with corresponding locks and handles. There is a kind of comprehensive hardware fittings that can be turned over 360 degrees in the world. The purpose is to achieve a good sealing effect and facilitate window cleaning.

Hardware accessories cover a wide range, such as kitchen hardware accessories, bathroom hardware, tool hardware accessories and so on. And the hardware of doors and windows introduced by Bian Xiao today. First of all, let me introduce the hinge to you. There are many kinds of hinges in door and window hardware fittings, such as load-bearing hinges, glass hinges, corner hinges, pipe hinges, corner hinges and so on. These all belong to the category of hinges, but they are subdivided in application to facilitate everyone's application and understanding of hinges. Don't underestimate hinge fittings. In our family life, its power.

railway

Speaking of tracks, I don't think everyone should be unfamiliar. So what is the track in the hardware fittings of doors and windows? The track is the push-pull translation track of doors and windows. The existence of the track can facilitate the opening and closing of doors and windows, prevent the wear of the edges of doors and windows, and protect doors and windows. We often say that the guide rails are sliding door guide rails, drawer guide rails, glass pulleys and so on. The track in the door and window hardware fittings is also made of various materials, such as stainless steel, aluminum alloy, plastic and a series of other materials, which are all popular track materials now and are often used to make tracks.

Door maker

The role of door suction in door and window hardware fittings should not be underestimated. Although it's just an unremarkable small accessory, its function is beyond your imagination. So what is the function of door suction? When the door is opened, a device for sucking and positioning the door leaf is to prevent the door from closing due to blowing or accidental collision, which can effectively protect the door leaf from external factors and also protect the door panel. This is what Bian Xiao understands as a doorstop. I didn't expect a small door bolt to make such a great power.

door closer

Door closers are one of the hardware fittings for doors and windows. The so-called door closer is a spring-like thing on the door head. When the door is opened, it can be compressed and released, and it can automatically close the door to protect it. It acts like a spring and can expand and contract freely. The door closer is installed to better open and close the door, which also plays a protective role and can be closed to a certain position more accurately. It is a rare product among hardware fittings for doors and windows. In normal times, as long as you are careful, you will often see this kind of hardware fittings for doors and windows.

In addition to the above-mentioned hardware fittings for doors and windows, there are many hardware fittings for doors and windows, mainly including bolts, change gears, anti-theft buckles, battens, door clips, plate pins, door mirrors, contact beads, magnetic contact beads, ground suction, ground springs and so on. , are pieces of useless steel, but in the process of installing doors and windows, these steel products have played their impeccable role, just like pieces of bricks.

The role of hardware fittings for doors and windows

1. The physical performance indexes of doors and windows are: wind pressure resistance, air tightness, water tightness, heat insulation, sound insulation and pressure resistance. The influence of hardware fittings on the main performance of doors and windows against wind pressure determines the success or failure of doors and windows; Similarly, air tightness, water tightness, heat preservation, heat insulation and sound insulation are all related to the sealing of doors and windows with the participation of hardware accessories. Hardware fittings lock points and lock seats are distributed around the whole door and window. When the door and window are locked, the lock point and the lock seat are firmly locked together, and cooperate with the hinge (hinge) or the sliding support to generate a strong sealing compression force, so that the sealing strip is elastically deformed, thus providing sufficient sealing performance for the door and window, and integrating the fan and the frame can greatly improve the performance of the door and window. Similarly, the opening and closing requirements of mechanical performance indexes (opening and closing force, repeated opening and closing) of doors and windows folding are also inseparable from the requirements of hardware accessories.

2. Doors and windows are lightweight components, and their energy consumption accounts for more than half of the building energy consumption, which is the top priority of building energy conservation. In the design, we should fully consider the energy-saving problem of doors and windows, that is, the problem of thermal insulation. If there is no multi-point lock hardware fittings, doors and windows can do better, and its thermal insulation can be imagined.

3. Similarly, the anti-theft performance of doors and windows is also the owner's most concerned issue. In this respect, the anti-theft performance of hardware fittings, especially the development of intelligent anti-theft door and window components, plays an important role.

4, doors and windows have a variety of window types and structural forms, all the functions of window types depend on the configuration of hardware accessories. Imagine, how can you open the hanging window horizontally and turn it upside down without hardware fittings? How to realize the push-pull folding function of sliding folding doors and windows? Inverted push and pull, movable louver, etc. , which does not rely on the role of hardware accessories to achieve its unique specific functions? It can be said that hardware fittings are the "heart" of door and window fittings.
