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.

[0004] However, this type of lock structure also has some shortcomings: the lock does not have a self-locking function. When the cover is closed, the cover and the cabinet are still loose, which makes it easy for the cover and the cabinet to shake relative to each other when moving; in addition, if the lock is not locked in time, the cover can still be opened unintentionally due to external force.

[0005] Therefore, how to provide a locking structure with a simple structure, easy operation, and a self-locking function so that the cover of the cabinet is always in a locked state when closed is an urgent problem to be solved by technical personnel in this field. Utility Model Content
