Abstract

The invention discloses a handle-driven lock body comprising a bottom plate, a plurality of lock tongues, a pulling device, a lock cylinder device and a handle. A lock tongue bottom plate is movably connected to the edge of the right side of the bottom plate. A pulling rod in the pulling device and the lock tongues are fixedly connected on the left and right sides of the lock tongue bottom plate correspondingly. The handle and the lock cylinder device are arranged in the positions, above and below the pulling rod, of the bottom plate correspondingly. A rack dragging block in the pulling device is movably connected on the pulling rod and connected with the handle in a transmission mode. When the handle is rotated clockwise, the rack dragging block drives an unlocking sliding piece in the lock cylinder device to move toward the pulling rod through a transmission device; a dragging rod is movably connected on the pulling rod, and one end of the dragging rod extends into a dragging hole formed in the rack dragging block under pushing of the end of the unlocking sliding piece; and the rack dragging block drives the pulling rod to move to pull the lock tongues back to the lock body. The lock tongues comprise the two pick-proof lock tongues and the tough lock tongue. The conception is ingenious, and the handle is rotated to drive a gear to complete all actions.

Description

technical field [0001] The invention relates to a lock body, in particular to a handle-driven lock body. Background technique [0002] The lock body is one of the components of the lock. There are many kinds of lock bodies, such as one-way lock body, three-way lock body, and four-way lock body. Generally used on anti-theft doors, it is responsible for the basic anti-theft work of anti-theft doors. The lock cylinder controls the operation of the lock body, and the lock body is responsible for opening and locking the doors and windows, and plays an important role in anti-theft. The current lock body can only be opened with a key outside the door, and after the door is used for a long time, there will be greater friction between the bolt and the door frame, as well as friction between the parts inside the lock body, and the size of the key is too small to withstand Large torsional force sometimes causes the key to break in the lock cylinder; and the transmission between the ha...
