Lock body and door lock

Abstract

This application relates to the technical field of locks, in particular to a lock body and a door lock. The door lock includes a front panel, a rear panel and the aforementioned lock body. The lock body includes: a lock housing; a front handle and a rear handle rotatably connected to the lock housing Handle; the lock cylinder and transmission shaft arranged inside the lock case, the transmission shaft is connected with the lock cylinder; the mechanical clutch mechanism is arranged between the transmission shaft and the front handle; the control key is arranged in the lock case for manipulating the mechanical clutch The mechanism is combined or disconnected. When the mechanical clutch mechanism is combined, the front handle is connected to the transmission shaft, so that the front handle can drive the transmission shaft to rotate, thereby unlocking the lock cylinder; when the mechanical clutch mechanism is disconnected, the front handle can be relatively idling on the drive shaft. The lock body provided by this application is combined with the manipulation key located inside the door through the mechanical clutch mechanism, which can control the combination of the mechanical clutch mechanism through the manipulation key inside the door so that the front handle is connected to the transmission shaft, so that the closed door lock can be transformed into a passage lock, and the rotation The front handle can also be unlocked to solve the problem of inconvenient use.
