Description

Technical Field

[0001] The utility model relates to the technical field of button locks, in particular to a button lock. Background Art

[0002] A push-button lock is a lock that unlocks by pressing a trigger. When locked, it typically has a flat or partially raised surface and is commonly used in environments such as boxes, cabinets, and fire hydrants. For example, patent number CN201320055513.3 discloses a push-button lock. However, during production and use, designers discovered that this push-button lock had the following defects:

[0003] 1. The unlocking trigger comprises a button, a card plate and a rotating arm which are separately arranged; the button is fixed to the panel with one end extending outward from the panel; the card plate is fixed to the inner side of the panel; the rotating arm is rotatably mounted on the lock housing and can press the card plate against the button; the assembly of the unlocking trigger is cumbersome, which is not convenient for reducing production costs and is also prone to jamming.

[0004] 2. The locking plate is installed on the back of the lock housing by a fixing screw and can be rotated and unlocked by the lock hook; the fixing bolt is installed on the lock housing by clamping a stretch collar, and the side of the stretch collar can be used to support the locking plate; the stretch collar is a small-sized stamping part with large dimensional error, and the locking and fixing stability of the screw is poor, which is not conducive to the installation and stability of the locking plate.

[0005] Therefore, further improvement is needed. Utility Model Content
