Blade lock head

Abstract

The invention discloses a blade lock head convenient for installing blades rotating flexibly. The blade lock head comprises a shell, a cylindrical lock core rotationally arranged in the shell and a columnar clamping pin; the side wall of the lock core is provided with a chute for installing the columnar clamping pin; the inner wall of the shell is provided with a groove matched with the columnar clamping pin at the corresponding position of the chute; and multiple groups of circular blades are arranged in the inner cylinder of the lock core in turn, each group of circular blades comprise a left blade and a right blade, the outer edges of the left blade and the right blade in each group of circular blades are provided with a clamping pin groove and a key through groove respectively, and a spring is arranged between the left blade and the right blade in each group of circular blades.

Description

technical field [0001] The invention relates to a lock head, in particular to a blade lock head. Background technique [0002] Chinese Utility Model Patent No. 01266248.8, published on August 7, 2002, discloses an anti-theft lock, comprising a housing, a cylindrical lock cylinder rotatably arranged in the housing, and a lock cylinder placed between the housing and the lock cylinder. Between the mating surfaces of the housing and the lock cylinder, the pin and key mechanism are used to prevent the mutual rotation of the shell and the lock cylinder. The lock cylinder includes a cylindrical inner lock cylinder and a cylindrical outer lock cylinder set outside the inner lock cylinder. The inner lock cylinder A number of circular grooves perpendicular to the axis are arranged parallel to the outer surface of the outer surface, and a pair of arc-shaped sliding pieces and a sliding piece compression spring are arranged symmetrically in each circular groove. The tail ends of the sl...

AI Technical Summary

Problems solved by technology

Because the lock head of the above structure uses a segment-shaped arc-shaped sliding piece as the sliding blade, a sliding piece pressure spring needs to be installed between each pair of sliding blades, so it is very difficult to install a line-segment-shaped arc-shaped sliding piece on the inner lock cylinder, and often requires a special fixture In addition, the sliding vane needs to slide radially, and the sliding performance of the arc-shaped sliding vane is not ideal.
