Description

Technical Field

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

[0002] A lock is a device used to connect or fix two or more objects. It is usually composed of one or more parts. It can connect objects together by insertion, snapping, rotation, etc., to play the role of fixing, locking or sealing. It has a wide range of applications. At present, many families place cabinets in their outdoor courtyards to store garden tools or other sundries, so that the courtyard looks more tidy and beautiful. The cover of the existing cabinet can be opened or closed. After the cover is closed, the cover can be locked on the cabinet by setting a suitable lock.

[0003] For example, the Chinese utility model patent "A cabinet lock structure" with application number 201620661877.X (authorization announcement number CN206137622U) discloses a lock structure, which includes a cover plate and a front side plate. The front side of the back of the cover plate is fixed with reinforcing rods distributed in the left and right directions, and a lock extending downward is formed on the reinforcing rod. A recessed portion concave inwardly is formed on the outer side of the front side plate near the upper edge, and a lock hole is opened on the recessed portion for cooperating with the lock. When the cover plate is closed, the lock can pass through the lock hole. Although the lock structure is very simple, it is relatively practical and reliable.
