Electromagnetic adsorptive plug type silent door lock

Abstract

The invention relates to an electromagnetic adsorptive plug type silent door lock. By adopting a brand new structural design, an electromagnetic structure is introduced. Based on a second notch (11) and a first notch (10) correspondingly designed on a lockset body seat (1) and a limiting seat (2), a magnet (9) and a plug bar body (4) without a spring are introduced. In a state that a door body anda door frame are closed, the magnet (9) attracts the movably arranged plug bar body (4) to lock and limit the closing state; meanwhile, a guide wire (8) winds the periphery of the side face of the plug bar body (4) to supply electricity to the guide wire (8) in a triggering manner. Based on an electromagnetic induction principle, the plug bar body (4) is magnetic. Based on the magnetic property,the magnetic properties of opposite end surfaces of the plug bar body (4) and the magnet (9) are opposite, so that a repulsive force between the magnet (9) and the plug bar body (4) is achieved, and closing and locking limit between the door body and the door frame is relieved. Therefore, silent operations of opening and closing the door are achieved.

Description

technical field [0001] The invention relates to an electromagnetic adsorption bolt type silent door lock, which belongs to the technical field of door locks. Background technique [0002] A door lock, as the name implies, is a device used to lock the door to prevent others from opening the door. There are many types of door locks, and the requirements for door locks are different in various occasions. Ordinary families generally use anti-theft door locks, which have high security and are relatively cheap. [0003] There are many kinds of existing door locks. The essence of the door lock is to insert the bolt bar structure between the door lock body and the corresponding limit hole, which is used to limit the misalignment of the door lock body relative to the corresponding limit hole, and then for the door body. The limit is realized with the door frame. The end surface of the elastic bolt on the existing door lock is a slope-shaped structure, which is to close the door body...

[0003] There are many kinds of existing door locks. The essence of the door lock is to insert the bolt bar structure between the door lock body and the corresponding limit hole, which is used to limit the misalignment of the door lock body relative to the corresponding limit hole, and then for the door body. The limit is realized with the door frame. The end surface of the elastic bolt on the existing door lock is a slope-shaped structure, which is to close the door body and the door frame. The slope-shaped surface of the elastic bolt end collides with the corresponding position to promote the recovery of the elastic bolt. When the door lock body When the position of the corresponding limit hole corresponds to each other, the elastic pin pops out again and is inserted into the corresponding limit hole. As mentioned above, in actual work, the slope at the end of the elastic pin will collide with the corresponding position of the door frame, so often The vibration will affect the firmness of the door lock. At the same time, the impact will cause sound, that is, closing the door will cause noise, which will bring a very inhumane closing experience.
