Double-magnetism mutual-push bolt ejection mechanism

Abstract

The invention relates to a double-magnetism mutual-push bolt ejection mechanism which comprises a lock body (9), a magnetic block (2), a rotary bolt mechanism and a bolt withdrawal mechanism, wherein the magnetic block (2) is arranged outside the lock body (9), the rotary bolt mechanism also comprises a rotary bolt (3) and a magnetic block (1), the magnetic block (1) is fixed on the rotary bolt (3), the rotary bolt (3) can rotate around a self rotating shaft (or a rivet or a pin which can penetrate through the rotary bolt (3)), the rotary bolt (3), the magnetic block (1) and the bolt withdrawal mechanism are all arranged in the lock body, and the rotary bolt mechanism is driven by a magnet arranged on a door frame and the bolt withdrawal mechanism. By adopting the double-magnetism mutual-push bolt ejection mechanism, an inclined tongue which extends to the outside of the lock body does not need to be arranged on the lock body, friction and collision with the door frame are not generated when the door is closed, the service life is long, and the appearance is attractive.

Description

technical field [0001] The invention relates to a deadbolt mechanism of door, window and lid locks. Background technique [0002] The lock body of a general door lock has one or more dead bolts, one of which is a dead bolt (or called an oblique bolt) with an inclined plane, and the dead bolt is normally in a state of protruding from the lock body. [0003] The working principle of the above door lock is: [0004] When closing the door, the inclined surface of the deadbolt first touches the door frame, and under the action of the extrusion force of the doorframe, the inclined bolt overcomes the elastic force of the deadbolt return spring and retracts into the lock body until the deadbolt is at the keyhole of the doorframe. The deadbolt loses the pressing force of the door frame on it. Under the action of the deadbolt return spring, the deadbolt pops out and is inserted into the lockhole to automatically lock the door (traditionally, the inclined-plane deadbolt with this func...

AI Technical Summary

Problems solved by technology

[0006] 1. The long-term collision and friction between the bolt and the door frame will cause mutual damage between the bolt, the door frame and the lock body, reducing the service life of the lock and the door

[0007] 2. The normal state of the oblique tongue is that the state of the lock body is not neat and unsightly, and it is easy to be hooked with people or objects, scratching the arm
