Abstract

A cylindrical locking mechanism, the structure of which is as follows: a keyhole 2 is provided at one end of a cylindrical lock body 1, and engaging recesses that can be engaged with a steering piece 3 are provided at appropriate intervals on two radially opposite sides of the lock body. One end of the engagement groove has an insertion hole 6 for the spring, so the steering piece 3 is installed in the engagement groove 4 and the insertion hole 6 together with the coil spring 5 respectively, and each steering piece 3 acted by the spring in the lock body is in the radial direction. Swipe up and opposite each other. The helical spring and the steering plate are oppositely installed from the two sides of the cylindrical lock body, so that the cylindrical reed lock can prevent illegal unlocking such as using a sharp small tool to open the lock for robbery.

Description

field of invention [0001] The present invention relates to a cylindrical locking mechanism, which is suitable for use as a locking mechanism such as a bicycle lock, and is characterized in that a coil spring and a steering plate are relatively installed from two sides of a cylindrical lock body to prevent illegal unlocking, such as with a sharp Gadgets to pick locks for theft. Background technique [0002] The traditional cylindrical locking mechanism is provided with a spring insertion hole and a steering plate assembly groove at an appropriate distance on the side (one side) of the cylindrical lock body, so the coil spring and the steering plate can be installed in the hole and the groove respectively. [0003] Japanese Patent No.2912600 discloses a cylindrical locking mechanism that reversely packs a coil spring and a steering piece from both sides of a cylindrical lock body, such as a steering piece locking mechanism. [0004] The traditional cylindrical locking mechani...
