What is the working principle of door suction? What are the requirements for the use of door suction? Next, Bian Xiao will answer your questions one by one.

First, the working principle of the door stop

Let's first understand the working principle of the lower door stop. The door stopper uses the mechanical principle to effectively replace the horizontal thrust outside the door with ground friction. A small door stopper can withstand at least several hundred kilograms of horizontal thrust. What is the concept of several hundred catties? It is equivalent to the horizontal thrust generated by 3-5 big men hitting the door together. Even if the door lock is broken, as long as there is Mense, the door cannot be pried open unless the bad guys smash the whole door.

A good doorstop is of high quality. If 3-5 big men push the door in, there will be two results. First of all, it can't be pushed away at all. The second is that the door was completely smashed. In the first case, the girls can have a good sleep. If it is the second case, the other party slams the door with iron bars, axes and other violent means, then you can at least use this time to call the police or try to escape.

Second, the use of door suction requirements

1, whether it is necessary to have automatic door stop function after opening the door;

2. Damping and buffering function: damping and buffering are generated after the door is quickly opened to a certain position, and the strength and range of damping and buffering can be adjusted according to the use requirements; This function is used to prevent the door or lock from colliding with the wall when opening the door quickly, or to prevent people from leaning forward and falling to the ground when opening the door quickly due to weightlessness during emergency escape.

3. Delayed slow door closing: the door closes slowly at a constant speed from the maximum position of opening the door, which can be adjusted steplessly according to requirements. Suitable for places where there are many ordinary people, especially hospitals, with doors and passages for the elderly, children and the disabled.

4. Adjustable closing force function: it can be installed on different doors with large door weight and wide range, as well as places with large closing resistance due to environmental reasons. Arbitrary stepless adjustment can obtain satisfactory closing force, which is especially practical in coastal cities and places where the wind resistance of vehicles and boats often changes.

5. Operating environment: fire prevention requirements (fire prevention requirements) and anti-freezing requirements (places with a temperature of minus 35 degrees in winter in the north).
