Lock core reinforced structure device with two different metallic parts

Abstract

A lock core reinforced structure device with two different metallic parts comprises a lock sleeve, a revolver and a gate. The lock sleeve provides disposition and combination of the revolver and includes some pin holes providing disposition of upper pinballs, springs and a stop pin. The revolver includes a key channel for insertion of a key and some pin holes providing disposition of lower pinballs. Additionally, the main body of the revolver is made of two different metallic materials combined together, where the front part of it is made of easily machined cast iron or copper and the rear part of it is made of steel material or heat treatment reinforced steel which has more structure strength. Furthermore, a gate room is formed beside an open end of the key channel and provides disposition of a gate and a spring, which is sealed and fixed by a keyhole cover. The gate is constantly pushed by the spring and moves upward to seal the open end of the key channel.
