Locking mechanism

Abstract

The invention discloses a locking mechanism. The locking mechanism comprises an inner cylinder, an outer cylinder, an arc-shaped section and a moving cylinder, wherein an inner cylinder protrusion anda clamping groove are arranged on the outer wall of the inner cylinder; the side wall, close to the inner cylinder protrusion, of the clamping groove inclines in the inner cylinder protrusion direction and is an inner cylinder inclined surface; the outer cylinder sleeves the inner cylinder, an annular gap is formed between the outer cylinder and the inner cylinder, and an outer cylinder protrusion is arranged on the inner wall of the outer cylinder; the side surface of the outer cylinder protrusion is inclined and is an outer cylinder inclined surface; the arc-shaped section is arranged between the inner cylinder and the outer cylinder and is provided with an inner inclined surface and an outer inclined surface; the moving cylinder is provided with a locking state and an unlocked state, in a locking state, one end of the moving cylinder extends into the annular gap to push the arc-shaped section to move towards the protruding direction of the inner cylinder; the inner inclined surfaceis contacted with the inner cylinder inclined surface; the arc-shaped section slides along the inner cylinder inclined surface in the direction far away from the clamping groove and is clamped between the inner cylinder protrusion and the outer cylinder protrusion; in an unlocked state, the moving cylinder moves in a direction far away from the arc-shaped section; the outer cylinder moves, so that the outer cylinder protrusion moves towards the direction of the inner cylinder protrusion; the outer cylinder inclined surface is contacted with the outer inclined surface to extrude the arc-shapedsection; and the arc-shaped section slides towards the clamping groove along the inner cylinder inclined surface and is separated from the space between the inner cylinder protrusion and the outer cylinder protrusion.

Description

technical field [0001] The application belongs to the technical field of locking mechanism structure design, and in particular relates to a locking mechanism. Background technique [0002] At present, the claw-type locking device is mostly used on the check bar, and the claw-type locking device has the following defects: [0003] 1), takes up a lot of space; [0004] 2), low carrying capacity; [0005] 3) Unlocking is inconvenient; [0006] Due to the above-mentioned defects of the claw-type locking device, the application reliability and stability of the claw-type locking device in the check bar are low. [0007] Therefore, it is desirable to have a technical solution to overcome or at least alleviate at least one of the above-mentioned drawbacks of the prior art. [0008] In view of the existence of above-mentioned technical defect, propose this application. [0009] It should be noted that the disclosure of the above background technical content is only used to assis...
