Description

Technical Field

[0001] The utility model belongs to the technical field of construction engineering, and particularly relates to a novel anti-detachment buckle. Background Art

[0002] The shackle is a detachable ring-shaped metal component that connects various rope eyelets and rigging;

[0003] Traditional shackles are usually connected by threads, and the thread grooves are prone to rust, which in turn causes the shackles to loosen easily and is not safe to use;

[0004] Therefore, anti-detachment buckles came into being. There are many types of anti-detachment buckle structures in the existing technology, and there may be some disadvantages. For example, some anti-detachment structures are relatively complex, have many components, are not easy to manage, are easy to lose, and are troublesome to install. Utility Model Content

[0005] The utility model provides a novel anti-detachment buckle, which can solve the problems pointed out in the background technology.

[0006] A new anti-detachment buckle includes a buckle body and a latch body. The latch body includes an insertion rod. The end of the insertion rod is provided with a limit groove extending along its length direction and a fixed shaft penetrating the thickness direction of the limit groove. A movable limit part is provided in the limit groove. The movable limit part has an elongated hole. The fixed shaft passes through the elongated hole. Through the limiting and rotational cooperation between the elongated hole and the fixed shaft, the movable limit part is in a limited state and a contact limited state. A resistance spring is provided deep in the limit groove. The resistance spring provides resistance to the movable limit part to stabilize it in the limited state.

[0007] Preferably, the movable limiting member is a rectangular plate, and a slope or arc surface is provided on a corner of the plate close to the resistance spring.

[0008] Preferably, a resistance spring limiting groove is provided deep in the limiting groove, and the resistance spring limiting groove is arranged along the length direction of the insertion rod.

[0009] Beneficial effects: The utility model provides a novel anti-detachment buckle, which integrates the anti-detachment component and the latch body into an integrated design, is easy to manage, not easy to lose, and is also more convenient to use. BRIEF DESCRIPTION OF THE DRAWINGS

[0017] A specific embodiment of the present invention will be described in detail below with reference to the accompanying drawings, but it should be understood that the protection scope of the present invention is not limited by the specific embodiment.

[0018] Example 1:

[0019] like Figure 1-5 As shown, the new anti-detachment buckle includes a buckle body 1 and a latch body, and the latch body includes an insertion rod 21. The end of the insertion rod 21 is provided with a limiting groove 22 extending along its length direction and a fixed shaft 23 passing through the thickness direction of the limiting groove 22. A movable limiting member 24 is provided in the limiting groove 22, and the movable limiting member 24 has an elongated hole 25. The fixed shaft 23 passes through the elongated hole 25. Through the limiting and rotation cooperation between the elongated hole 25 and the fixed shaft 23, the movable limiting member 24 is in a limiting state (locked state) and a contact limiting state (open state). A resistance spring 26 is provided deep in the limiting groove 22. The resistance spring 26 provides resistance to the movable limiting member 24, so that it is stable in the limiting state.

[0020] Specifically, the movable limit member 24 is a rectangular plate, and a slope or arc surface is provided on a corner thereof close to the resistance spring 26. When the movable limit member 24 rotates or slides with the fixed shaft 23, this corner of the movable limit member 24 will contact the outer end of the resistance spring 26. Setting this corner as a slope or arc surface is conducive to the smoothness of the movement.

[0021] Specifically, a resistance spring limiting groove is provided deep in the limiting groove 22 , and the resistance spring limiting groove is provided along the length direction of the insertion rod 21 .

[0022] The working principle of this utility model: Figure 1 As shown, the movable limiting member 24 is rotated to a state parallel to the latch body, that is, the limiting state is released; Figure 2 As shown, the movable limiting member 24 is rotated to a state perpendicular to the latch body, that is, in a limiting state.

[0023] The above disclosures are only a few specific embodiments of the present invention. However, the embodiments of the present invention are not limited thereto. Any changes that can be conceived by those skilled in the art should fall within the scope of protection of the present invention.
