Structure of the lock cylinder and key

Abstract

This invention provides a lock cylinder and key structure. The lock cylinder includes a lock cylinder seat, a lock cylinder shell, a push plate, a limiting plate, a number of locking plates and a number of washer plates, a positioning plate, a locking lever, a brake plate, a compression spring, a positioning stop plate, and a retaining ring. The push plate is disposed in a groove on the bottom surface of the lock cylinder shell. A positioning guide strip is provided on the push plate and is disposed in a guide groove of the lock cylinder shell. The limiting plate is disposed on one side of the push plate. The number of locking plates and the number of washer plates are stacked on top of each other in the lock cylinder shell. The positioning plate is disposed in the lock cylinder. The outer end of the housing is inserted into the lock cylinder seat along with the lock cylinder housing. The brake plate is located in the receiving groove of the lock cylinder seat. The compression spring is located in the groove of the lock cylinder seat and pushes against the brake plate. The positioning baffle is located in the cavity of the lock cylinder seat and at the bottom of the lock cylinder housing. The buckle is embedded in the annular groove of the lock cylinder seat. The front end of the key has an annular groove. In this way, the lock plates will not be rotated when the key is not fully inserted into the bottom surface of the lock cylinder housing, thus achieving the best anti-theft effect.
