What is the hotel's device for limiting window opening?

The device for limiting the opening of windows in hotels is the door and window limiter, which, as the name implies, refers to the limiting device for limiting the opening of doors and windows.

The principle of door and window stopper is that the slider in the cover plate of the stopper moves back and forth on the main arm during the process of opening and closing the door. Due to the different thickness in the direction of motion trajectory, the displacement distance of the slider is also different, so different window opening and closing forces will be generated during the window opening and closing process to achieve the limit effect. Because it is hardware, we should pay attention to rust prevention and lubrication in daily use, otherwise it will rust and make abnormal noise.

Risks of using door and window restrictors

1. After long-term use of this structure, the chute on the fixed bracket is seriously worn, the positioning effect of the limiting brace is obviously reduced, and the service life is shortened.

When the wind is too strong, that is, when the thrust of the window sash is greater than the friction, it is easy to close the window suddenly, which can not guarantee the safety and reliability of the doors and windows in the open state, and it is also easy to damage the parts on the doors and windows, which will endanger the safety of people near the doors and windows, shatter the glass and bring losses to users.

3. The above-mentioned limit device is not adjustable, that is, its limit size cannot be adjusted according to its wear condition in the working process to ensure the normal limit function, and the reduction of service life will inevitably lead to the increase of production cost and the waste of resources.
