Embodiment Construction

[0025] The present invention will be further elaborated by the following examples.

[0026] see Figure 1-Figure 12 As shown, the lock cylinder of a floating locking pin blade structure consists of a circular lock cylinder shell 1, a circular lock cylinder body 6, a dial wheel 3, an arc-shaped sliding blade 5, an arc-shaped control blade 8, an arc-shaped support The sheet 4, the first return spring 10, the second return spring 14 and the third return spring 7 are composed. The lock cylinder body 6 is placed in the lock cylinder shell 1 and is concentric with the lock cylinder shell 1, the dial wheel 3 is located outside the lock cylinder shell 1 and is tightly connected with the extension shaft 6-2 of the lock cylinder body 6, and the dial wheel 3 is connected to the lock cylinder body 6. The tongue is rigidly connected, and the dial 3 drives the lock tongue to open or close. A first arc-shaped groove 13 parallel to the central axis of the lock cylinder body 6 is symmetrical...

Abstract

A lock cylinder with a floating lock pin blade structure, the inner circle side of the lock cylinder shell is symmetrically opened with a first axial arc-shaped groove on the upper and lower sides, and the left and right ends of the lock cylinder body corresponding to it are There is a second arc-shaped groove, and the body of the lock cylinder has a first arc-shaped stepped groove. The two second arc-shaped grooves on the same side are hollowed out and the third return spring is placed. The second arc-shaped groove The arc-shaped supporting piece is placed in the groove, and the ends of the two locking pins are respectively supported on the arc-shaped empty slot in the middle of the corresponding arc-shaped supporting piece. There are 3 to 12 radial ring C-shaped grooves on the body of the lock cylinder. A ring C-shaped groove located at the left and right ends of the body of the lock cylinder is sequentially equipped with a horizontal partition, a first return spring, an arc-shaped control blade, a key slot, an arc-shaped control blade, and a first return spring. Arc-shaped sliding vanes, the second return spring and the like are housed in the C-shaped grooves of the remaining rings. The lock cylinder can effectively defend against electronic unlocking guns or technical unlocking.

Description

technical field [0001] The invention relates to the technical field of mechanical locks, in particular to a lock cylinder with a floating locking pin blade structure. Background technique [0002] The existing blade structure has a lock cylinder with a locking pin. The locking pin can only move up and down, and cannot move in the horizontal direction. When each blade slides left and right under the action of the key, its groove reaches a predetermined position and the locking pin The lock can be unlocked by matching the fit. The lock cylinder of this kind of locking pin blade structure with only one-dimensional movable space will be quickly knocked open and cracked when encountering technical unlocking or using an electronic unlocking gun to rapidly and continuously move the blade. SUMMARY OF THE INVENTION [0003] The purpose of the present invention is to provide a lock cylinder with a floating locking pin blade structure, which can effectively prevent the electronic un...
