Problems solved by technology

[0005] In the lock body, the main bolt is opened and closed by the key to expand and contract, while the auxiliary bolt is mainly driven by the inner handle or the outer handle to expand and contract. The main bolt first keeps shrinking after the door is opened, and the auxiliary bolt The preferred state is to keep the extended state, that is to say, the extended state of the auxiliary bolt is its normal state. The defect is that when the residents enter and exit the door, the clothes are easily caught and entangled by the auxiliary bolt, so the door will be against the will. Active, and the protruding secondary lock tongue is sharp, there is a risk of scratches

Embodiment 1

[0047] The first embodiment has a modified structure, and the difference is that the elastic component and the guide post interference portion 141 are fixedly assembled. Specifically, the guide column 140 includes a guide column side 142, the guide column interference portion 141 is located at the guide column side 142, the elastic member includes a main deadbolt set 300, and the main deadbolt set 300 includes a main deadbolt set inner profile 310 and a main deadbolt The kit outer profile 320, the main deadbolt kit inner profile 310 is sleeved and assembled outside the guide column side 141, the main deadbolt kit inner profile 310 is fixedly assembled with the guide post side 142, the main deadbolt kit outer profile 320 and the guide groove conflicting part 122 contradicting installation.

[0048] In the case where the main lock tongue set 300 is fixedly assembled with the guide post interference portion 141 , the main lock tongue pressing part 400 can be omitted.

Embodiment 2

[0072] The difference between the auxiliary bolt mechanism of the second embodiment and the auxiliary bolt mechanism of the first embodiment is that the auxiliary bolt 160 keeps shrinking in the lock seat 100 in the normal state, and is always affected by the auxiliary bolt limiting device 191. Specifically, the auxiliary bolt limiting device 191 includes a slider 180, a fixed block 192, and a compression spring 193. The following is subject to the equilibrium state of the stage clip 193, and the slider 180 is in a linkage relationship with the auxiliary bolt link 170. The auxiliary bolt link 170 and the slide block 180 cannot overcome the pressing effect of the stage clip 193 in the equilibrium state, so Secondary deadbolt link 170 is constrained to figure 1 In the lower position, the auxiliary dead bolt 160 shrinks in the lock body 1.

[0073] The lock catch 2 is fixedly installed on the door frame, and the lock catch 2 is stationary relative to the door frame. The basic st...

Abstract

The technical scheme of the door lock of the present invention is: including a lock body and a lock catch, the lock body includes a lock base, a guide column, a main bolt, a main bolt link, an auxiliary bolt and an auxiliary bolt limiting device, and the lock catch includes an auxiliary bolt The deadbolt buckle, the main deadbolt and the main deadbolt link are fixedly assembled, the guide column and the lock seat are fixedly assembled, the main deadbolt link is provided with a guide groove, and the guide groove is sleeved and assembled outside the guide post. The whole lock tongue link rod is movable relative to the guide column. The guide column has a guide column interference part, and the guide groove has a guide groove interference part, including a main lock tongue buffer device, which isolates the guide post interference part from the guide groove interference part, the lock body includes an auxiliary bolt magnet, an auxiliary bolt stopper, the auxiliary bolt includes an auxiliary bolt chamber, the auxiliary bolt chamber includes an opening of the auxiliary bolt cavity, and the auxiliary bolt magnet and the auxiliary bolt stopper are accommodated and assembled in the auxiliary bolt The deadbolt cavity and the secondary deadbolt stopper are assembled between the secondary deadbolt magnet and the secondary deadbolt chamber opening, and the secondary deadbolt stopper and the secondary deadbolt are fixedly assembled.

Description

technical field [0001] The invention relates to a door lock, in particular to a door lock which effectively reduces noise and has an automatic adsorption function. Background technique [0002] The door lock is a hardware designed for space privacy. The basic structure includes a lock body and a lock catch. The lock body is assembled on the door, and the lock catch is assembled on the door frame. A common lock body includes a lock seat, a main bolt, and an auxiliary bolt. The lock seat is statically assembled on the door, and the main and auxiliary bolts are all movably assembled relative to the lock seat. The main and auxiliary lock holes of the lock on the lock match. [0003] In the lock body, the main dead bolt is fixedly assembled with the main dead bolt link, and the auxiliary dead bolt is fixedly assembled with the auxiliary dead bolt link. [0004] In the lock body, the lock seat includes a guide column, and the guide column and the lock seat are fixedly assembled....
