[0002] In the prior art, latch locks are a common locking device widely used in various access control systems, furniture and mechanical equipment. However, this type of lock has certain stability problems during use. Specifically, the existing latch lock cannot stably fit the handle to the baffle when locked, which may cause the lock to shake or loosen during use, thereby affecting the stability and service life of the lock.

[0003] Furthermore, this stability problem is particularly prominent in practical applications. Due to the unstable fit between the handle and the baffle, the lock may be displaced or loosened when subjected to external forces, which not only affects the functionality of the lock, but also poses a potential threat to the user's safety. This stability problem is particularly important in situations that require high security or frequent use. Utility Model Content

[0015] (III) Beneficial effects

[0016] Compared with the prior art, the utility model provides a latch lock having the following beneficial effects:

[0017] 1. The design of the elastic mechanism enables the latch lock to provide a stable rebound force to ensure the stability of the handle's fit on the baffle. Through the cooperation of the expansion spring, the limit ring, the fitting ring and the middle ring, the user can easily adjust the position of the handle and maintain a stable fit between it and the baffle. The rebound force of the expansion spring can resist the influence of external forces and prevent the handle from being displaced or loosened during the use of the lock, thereby improving the stability and service life of the latch lock.

[0018] 2. The insertion mechanism realizes the quick connection and fixation of the latch lock through the cooperation of the threaded ring and the retaining ring.
