Bearing lock

Abstract

The invention discloses a bearing lock which comprises a lock-body upper / lower cover plate and a lock-body latch bolt square-hole shift fork, wherein the lock-body upper / lower cover plate is provided with a hole, and the lock-body latch bolt square-hole shift fork passes through the hole of the lock-body upper / lower cover plate and rotates in the hole. The bearing lock is characterized in that a bearing is arranged between the lock-body upper / lower cover plate and the lock-body latch bolt square-hole shift fork; the bearing is arranged at the two sides of a contact position of the lock-body latch bolt square-hole shift fork and the lock-body upper / lower cover plate; and the contact position of the lock-body upper / lower cover plate and the lock-body latch bolt square-hole shift fork is provided with an annular concave step, and the bearing is arranged in the annular concave step. The bearing lock has the advantages that after the bearing is arranged between the lock-body upper / lower cover plate and the lock-body latch bolt square-hole shift fork, rotating balls in the bearing are rotated so that the friction between metals eliminated, and the rotation part is ensured to rotate smoothly and flexibly, thus the handfeel for handling the lock is better and more comfortable; and the bearing is originally used in machines rotating at a high speed, but now, the bearing is used in machines which does not rotate at a high speed, thus the service life of the lock body is longer.

Description

technical field [0001] The invention relates to a lock, in particular to a lock with better hand feeling, more comfortable and smoother handle, longer service life of the lock body and more perfect structure. Background technique [0002] The structure of an ordinary lock generally includes a lock body, a lock head and a key. There are oblique tongues and square tongues for rotation and locking on the lock body. There is a lock cylinder in the lock head. Inserts into the knob on the lock body. When the key is inserted into the lock cylinder and the lock cylinder is twisted, the knob can be driven through the transmission of the lock ruler, thereby driving the lock tongue. The square hole part of the existing lock body is in direct contact with the upper and lower cover plates of the lock body. Every time it rotates, there will be friction between the two. Long-term friction between metal and metal will produce a gap, which will become larger and larger as time goes by. And...

AI Technical Summary

Problems solved by technology

The square hole part of the existing lock body is in direct contact with the upper and lower cover plates of the lock body. Every time it rotates, there will be friction between the two. Long-term friction between metal and metal will produce a gap, which will become larger and larger as time goes by. And parts will become looser and shake more, so there are potential safety hazards
