Description

Technical Field

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

[0002] A handle lock is a common type of lock, usually installed on the outside of the door. The lock is unlocked or locked by turning or pressing the handle. The handle lock does not necessarily have a "handle" in the traditional sense. From the perspective of traditional design, the handle lock is equipped with a handle mainly to facilitate people's operation. The handle is held and turned or pushed to unlock and lock. However, in modern lock design, some innovative forms have emerged. Some handle locks may adopt a more simple design, such as a small knob or button to replace the traditional large handle. For example, some smart home door locks may only have a small rotary button to control the state of the lock. Some special-purpose handle locks may have no protruding operating parts at all, but unlock and lock through induction, electronic control, etc., and there is no "handle" in the physical sense at this time.

[0003] Existing handle locks are generally installed directly on the surface of the door. Although they are generally not eroded by rain, air flow will still drive dust and impurities into the lock core, thereby increasing the wear of the lock core, shortening the service life of the lock core, and reducing the overall practicality of the lock body.
