Description

Technical Field

[0001] The utility model relates to the technical field of lock cases, in particular to a novel lock case structure. Background Art

[0002] Locks can lock valuables to prevent theft. Almost every door is equipped with a lock. Door locks are generally composed of a handle, lock cylinder, lock slot, lock shell, lock tongue and various parts inside the lock.

[0003] However, the slanted lock tongue of traditional door locks often malfunctions because the slanted lock tongue often collides with the lock slot and becomes deflected, and the connecting rod of the slanted lock tongue slides in the sliding slot on the lock shell. After long-term use, the lock shell wall around the sliding slot will be deformed, causing the connecting rod to not slide normally, which in turn causes the slanted lock tongue to often get stuck in the lock shell and cannot come out, or causes damage to the internal parts of the lock. The current lock shell does not have the function of disassembly and assembly. Damage to internal parts requires the entire lock to be replaced, and maintenance and parts replacement are impossible. Therefore, a new lock shell structure is needed to solve this problem. Utility Model Content
