Description

Technical Field

[0001] This utility model relates to the field of mechanical locks, and in particular to a lock body that prevents accidental triggering. Background Technology

[0002] In daily life and work, locks are essential tools for protecting property and personal safety. Traditional mechanical locks require manual operation of keys or handles to lock and unlock. People expect locks to be more convenient, with automatic mechanical locks eliminating the need for manual bolt operation and automatically locking and verifying when the door is closed, meeting the demands of a fast-paced lifestyle. However, existing automatic mechanical locks have the following shortcomings: the self-springing trigger condition is a single condition that causes the main bolt to spring out. Even when the door is open, touching the detection bolt will cause the main bolt to spring out, and if the door is not fully closed and is reopened, the main bolt will also spring out. Closing the door in this unpredictable state can lead to the main bolt colliding with the doorway, preventing the door from closing properly, and damaging both the lock body and the door.

[0003] In order to solve the problems existing in the background technology, this utility model provides a lock body that prevents accidental triggering. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by providing a lock body that prevents accidental triggering.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A lock body designed to prevent accidental triggering includes a guide plate, a lock body, a bolt assembly, and a bolt actuating plate assembly. The bolt assembly includes a bolt, a linkage rod, a bolt limiting groove, a bolt actuating plate, and a bolt limiting plate. The lock body also includes a bolt detection assembly, a bolt bevel assembly, a separating plate, and a bolt triggering hook assembly. The front end of the bolt limiting plate is rotatably connected to the end of the linkage rod, and the other end abuts against or separates from the lower part of the bolt bevel assembly. The lower part of the bolt has a bolt limiting groove. One side of the bolt actuating plate is connected to the bolt limiting groove via a through shaft, and the other side is connected to the sliding groove of the linkage rod via a stud.

[0007] The detection mechanism detects that the end of the tongue assembly hooks with the separating plate, the lower part of the separating plate abuts against the upper part of the tongue trigger start hook assembly, and the rear end of the tongue limiting plate abuts against the lower part of the tongue fixing plate of the tongue assembly; or the detection mechanism detects that the end of the tongue assembly separates from the separating plate, the lower part of the separating plate separates from the upper part of the tongue trigger start hook assembly, the rear end of the tongue limiting plate abuts against the tongue bottom plate of the downward pressing tongue assembly and separates from the tongue fixing plate, and the tongue trigger start hook assembly separates from the lower part of the tongue assembly, and the tongue actuating plate is hooked to the tongue trigger start hook assembly.

[0008] Furthermore, the latch trigger start hook assembly includes a start hook, a start hook limiting plate, and a start hook spring. The lower end of the start hook is rotatably connected to one end of the start hook limiting plate. One end of the start hook spring is connected to the start hook, and the other end is connected to the lock body. The end of the start hook is provided with multiple serrated steps, and the lower part of the separation plate abuts or separates from the protrusion on the upper part of the start hook limiting plate.

[0009] Furthermore, a torsion spring is fitted on one side of the latch actuating plate shaft. One end of the torsion spring abuts against the actuating plate stud on the latch actuating plate, and the other end abuts against the lock body stud inside the lock body.

[0010] Furthermore, a linkage push plate is provided on one side of the lower part of the lock tongue, and a hanging groove is provided in the middle of the lock tongue. The bottom of the linkage push plate is rotatably connected to the lower part of the lock tongue, and the hook at the upper end of the linkage push plate is hooked or separated from the hanging groove.

[0011] Furthermore, a lower hook is provided on one side of the bottom of the linkage push plate, and an upper hook is provided on the same side as the lower hook at the bottom of the locking tongue. The linkage push plate spring is hooked between the lower hook and the upper hook.

[0012] Furthermore, the detection tongue assembly includes a detection tongue, a detection tongue guide, a detection tongue limiting plate, and a detection tongue spring. The detection tongue limiting plate is fixed in the lock body. The detection tongue has a triangular cross-section. The bottom of the detection tongue is fixed to the detection tongue guide by bolts. The detection tongue limiting plate is provided at the lower part of the detection tongue guide. One end of the detection tongue spring is connected to the bottom of the detection tongue, and the other end is connected to the detection tongue limiting plate and is sleeved on the detection tongue guide. When the detection tongue is pressed down, it causes the detection tongue guide to separate from the upper part of the separation plate and is reset by the detection tongue spring.

[0013] Furthermore, the upper part of the separator is provided with a positioning post on the separator, and the tail of the detection tongue guide is bent to one side to form a guide hook, which is used to hook or separate from the positioning post on the separator.

[0014] Furthermore, the latch assembly also includes a latch and a latch spring. A latch guide is fixed at the bottom of the latch, and a fixed latch base plate is provided at the bottom of the latch guide. The latch fixing plate is connected to the lock body, and the latch guide moves in the latch fixing plate. One end of the latch spring is connected to the bottom of the latch and the other end is connected to the latch fixing plate.

[0015] Furthermore, a reset torsion spring fixing plate is provided on one side of the inclined tongue base plate, and the inclined tongue reset torsion spring is connected to the reset torsion spring fixing plate.

[0016] Furthermore, the middle of the oblique tongue fixing piece is provided with a U-shaped notch for the oblique tongue guide to pass through and move.

[0017] The advantages of this utility model are as follows: when the door is opened and closed, the detection tongue and the beveled tongue retract into the lock body simultaneously. Under the condition that the detection tongue remains pressed, the main lock tongue automatically pops out and locks. Pressing the beveled tongue individually or pressing the detection tongue and the beveled tongue simultaneously and releasing the main lock tongue at the same time will not trigger locking. Therefore, it effectively solves the problem of collision damage between the lock body and the door caused by accidental triggering of the lock body under a single condition. The lock body of this structure automatically locks the door when the door is closed, and it is more energy-efficient when used with a smart lock. Attached Figure Description

One end of the detection tongue spring 8 is connected to the bottom of the detection tongue 21, and the other end is connected to the detection tongue limiting plate 6 and is sleeved on the detection tongue guide 22. When the detection tongue 21 is pressed down, it causes the detection tongue guide 22 to separate from the upper part of the separation plate 10 and is reset by the detection tongue spring 8.

[0037] The upper part of the separation plate 10 is provided with a positioning post 16 on the separation plate, and the tail of the detection tongue guide 22 is bent to one side to form a guide hook, which is used to hook or separate from the positioning post 16 on the separation plate.

[0038] The latch assembly 9 also includes a latch 26 and a latch spring 27. The bottom of the latch 26 is fixed with a latch guide, and the lower part of the latch guide is provided with a fixed latch bottom plate 31. The latch fixing plate 14 is connected to the lock body 2, and the latch guide moves in the latch fixing plate 14. One end of the latch spring 27 is connected to the bottom of the latch 26 and the other end is connected to the latch fixing plate 14.

[0039] A reset torsion spring fixing plate 20 is provided on one side of the tongue base plate 31, and the tongue reset torsion spring 19 is connected to the reset torsion spring fixing plate 20.
