Description

Mechanical structure improved mortise lock Technical Field The utility model relates to the technical field of locks, in particular to an improved mortise lock with a mechanical structure. Background In daily life, the mechanical mortise lock is widely applied to various door tools and bears important responsibilities for ensuring safety. However, the lock cylinder is exposed to the external environment for a long period of time and is extremely vulnerable to dust. Once dust enters the lock core, the dust is accumulated on the contact surface of the lock core and the key, so that the abrasion of lock core components can be accelerated, the service life of a lockset is reduced, the key is difficult to insert and pull, and the use experience of a user is seriously influenced. At present, a common dustproof technology is to install a simple rubber dustproof cover outside a lock cylinder. The dust cover can prevent larger particle dust from directly falling into the lock cylinder hole to a certain extent, and plays a primary protective role. But has significant limitations in its protective effect. On one hand, fine dust can still enter through gaps between the dust cover and the lock cylinder, damage to the lock cylinder can still be caused due to accumulation of time and month, and on the other hand, the dust cover only has a dust-proof function, and dust entering the periphery of the lock cylinder cannot be effectively cleaned. Over time, the dust accumulation problem still cannot be solved at all, which has prompted us to develop a more complete dust-proof, dust-blocking and dust-blowing integrated solution. Disclosure of utility model (One) solving the technical problems Aiming at the defects of the prior art, the utility model provides the mechanical structure improved mortise lock which has the advantages of comprehensive protection, automatic cleaning and prolonged service life of the lock, and solves the problems that the traditional rubber dust cover cannot block fine dust and cannot clean the dust and the lock core cannot be worn and used conveniently due to dust accumulation.
