Installation method and adjustment method of miniature door closer

Miniature door closers are the most common decoration gadgets in our lives, which are mainly used in some large buildings, shopping malls and office buildings. Its advantage is that it can be used at the entrance of buildings to limit the spread of fire and ensure life safety. There are also several miniature door closers, such as external door closers, embedded door closers, door bottom springs and ground springs. Below I will introduce the installation method and adjustment method of the micro-door closer to you, hoping to help you.

First,? Installation method of door closer

1. Standard installation:

The door closer is installed on the door, the bracket is installed on the door frame, and the door closer is installed on the sliding door side.

This installation method is suitable for the case that the door frame is narrow and there is not enough space to install the door closer.

This installation method is suitable for the door opening direction without obstacles. When the door is opened to a large enough angle, the door closer will not hit foreign objects.

2. Install the upper door frame:

The door closer is installed on the door frame, the bracket is installed on the door, and the door closer is installed on the push door side.

This installation method is suitable for occasions where the door frame is wide and there is enough space to install the door closer.

Compared with standard installation, this installation method is suitable for obstacles such as walls in the direction of door opening.

Compared with the standard installation, this installation method has greater closing force and is suitable for larger and heavier doors.

3. Parallel installation:

The door closer is installed on the door and the parallel plate is installed on the door frame. And the door closer is installed on the push door side.

This installation method is suitable for cases where the door frame is narrow or almost no door frame.

After this installation, it is more beautiful because there is no protruding connecting rod and rocker arm.

Compared with standard installation, this installation method is suitable for obstacles such as walls in the direction of door opening.

Compared with the standard installation, this installation method has less closing force.

4. Slide rail installation:

Generally, the door closer is installed on the door and the sliding rail is installed on the door frame. Door closers can be on both sides of the door.

Compared with the first three installation methods, this installation method has the smallest closing force.

After this installation, it is more beautiful because there is no protruding connecting rod and rocker arm.

5. Hide the installation:

This installation method is aimed at hidden door closers? , the installation method is the same as the slide rail installation.

Compared with the first three installation methods, this installation method has the smallest closing force.

After this installation, the door is closed and there is no exposed part, so it is the most beautiful.

This installation method is the most complicated, and it is best to install it by professionals.

This installation method requires a large gap between the door and the door frame, generally 10mm (or remove the material on the upper part of the door to increase the gap). The thickness of the door exceeds 42 mm.

6. Judge the direction of opening the door:

People stand in the direction of pushing the door. The hinged door on the right is the right hand door, and the hinged door on the left is the left hand door.

Second, the correct adjustment method of the door closer

Almost all door closers have two adjustable functions: closing speed and locking speed. The locking speed is adjusted according to the hardness of the lock tongue, so as to lock the movable fan without generating unnecessary impact on the door frame. However, the adjustment of the whole closing speed is not affected by the locking speed.

Opening damping is a very important function for building exterior doors. Because the door closer should not only prevent the movable fan from being excessively opened by the huge thrust of people, but more importantly, it should prevent the movable fan from being damaged by strong wind when it is opened. Generally speaking, only high-grade door closers have this function.

Lagging door closing is a special function, which aims to make the movable fan stay in the open position for a period of time and then close the door. This function is very important when children and old people pass by.

Adjustable closing force is the symbolic significance of high-grade door closers, which can accurately adjust the closing force level. The closing force is usually the concrete expression of a certain type of door closer, but sometimes the closing force will change. For example, when the wind is strong in winter, the external door may need a larger closing force, while when the summer monsoon is small, it may need a smaller closing force, which makes it easier for people to turn on the movable fan.

It is also an important function to stop moving the fan, but special equipment such as fire doors can never be set with the stop function.

The above is the introduction of the installation method and adjustment method of the micro door closer I introduced to you, hoping to help you. Due to the wide application of door closers, it is necessary for us to understand these related installation and adjustment methods so as not to deal with these problems in time. In addition, if this miniature door closer is installed at home, it can be easily installed and adjusted. I hope the above introduction can help friends in need in this respect.
