Lock body and door lock

Abstract

The invention relates to the technical field of locksets, and specifically relates to a lock body and a door lock. The door lock comprises a front face plate, a rear face plate and the lock body. Thelock body comprises a lock shell, a front handle, a rear handle, a lock cylinder, a transmission shaft, a mechanical separation and connection mechanism and a control key. The front handle and the rear handle are connected to the lock shell in a rotatable manner. The lock cylinder and the transmission shaft are arranged in the lock shell. The transmission shaft is connected with the lock cylinder.The mechanical separation and connection mechanism is arranged between the transmission shaft and the front handle. The control key is arranged on the lock shell and used for controlling combinationor disconnection of the mechanical separation and connection mechanism. When the mechanical separation and connection mechanism is combined, the front handle is connected with the transmission shaft so that the front handle can drive the transmission shaft to rotate and the lock cylinder can be unlocked. When mechanical separation and connection mechanism is disconnected, the front handle can idlerelative to the transmission shaft. According to the lock body, by means of combination of the mechanical separation and connection mechanism and the control key located inside a door, combination ofthe mechanical separation and connection mechanism can be controlled through the control key inside the door so that the front handle can be connected with the transmission shaft, a door closing lockis changed into a passage lock, unlocking can also be achieved by rotating the front handle, and the problem of use inconvenience is solved.

Description
