Integrated square tube of handle lock

Abstract

The invention discloses an integrated square tube of a handle lock. The integrated square tube of the handle lock comprises a cover and a column, wherein the cover and the column are of an integratedstructure. The column is arranged at the bottom of the cover. A through groove is formed in the bottom of the cover and communicates with the inner wall of the column. A circular groove is annularly formed in the inner wall of the cover. According to the integrated square tube, the cover and the column are of the integrated structure, the column is arranged at the bottom of the cover, and the square through groove is formed in the bottom of the cover and communicates with the inner wall of the column, so that the problem that in the prior art, a square hole shifting fork of a handle lock in direct and mechanical contact with a cover plate is likely to be separated from the cover plate, and consequentially, potential safety hazards can be caused is solved; and the integrated square tube isunlikely to get loose in use and thus is good in safety performance.

Description

technical field [0001] The present invention relates to the technical field of handle lock accessories, in particular to a handle lock with integral square connection. Background technique [0002] Handle locks are widely used in people's daily life, and there are many styles of locks. Handle locks in real life need to be rotated by the handle to open the oblique tongue. The ordinary lock body directly installs the handle directly in the lock body On the journal of the square core rotating shaft (or square hole shift fork), since the square hole shift fork and the cover plate are in direct mechanical contact, the friction force is large, and it is easy to produce abnormal sound and noise. Long-term twisting will cause Make it produce gap, be easy to separate, have the problem of potential safety hazard, and its safety performance is relatively poor. Contents of the invention [0003] In view of the defects in the above-mentioned prior art, the technical problem to be solv...

AI Technical Summary

Problems solved by technology

[0003] In view of the above-mentioned defects in the prior art, the technical problem to be solved by the present invention is to provide a handle lock with an integral square connection, which solves the problem that the direct mechanical contact between the square hole shift fork and the cover plate in the above handle lock is easy to separate, and there is safety. There are hidden dangers, and it is not easy to loose during use, and the safety performance is good
