Description

Technical Field

[0001] The utility model relates to the technical field of soft shackles, in particular to an explosion-proof connecting buckle. Background Art

[0002] The explosion-proof connecting buckle, also known as the soft shackle, is made of a synthetic fiber rope cross-woven. It is mainly used as a tool for off-road self-rescue or trailer rescue. Compared with the traditional iron U hook, the connecting buckle has the advantages of flexible connection, light material, strong adaptability to working conditions and higher strength. When the connecting buckle is in use, it needs to be passed around the towing ring on the vehicle. After the two ends of the connecting buckle are connected, a ring-shaped rope buckle is formed. Then, after the pull rope is connected to the connecting buckle, the pull rope can be pulled by the vehicle to perform pulling and rescue work. After the connecting buckle is connected into a ring structure, the surface of the connecting buckle will rub against the towing ring on the vehicle. After long-term work, the surface of the connecting buckle will be worn, thereby affecting the service life of the connecting buckle. Utility Model Content

[0003] The purpose of the utility model is to avoid the deficiencies of the prior art and provide an explosion-proof connecting buckle, thereby effectively solving the deficiencies in the prior art.

[0004] To achieve the above object, the technical solution adopted by the utility model is: an explosion-proof connecting buckle, comprising a connecting buckle body, one end of the connecting buckle body is provided with a diamond knot, the other end of the connecting buckle body is provided with a rope buckle, and the middle part of the connecting buckle body is provided with a protective sleeve;

[0005] The protective sleeve is provided with a plurality of protrusions evenly distributed along the circumferential direction on the outer side thereof, and a cavity is provided inside the protective sleeve at a position corresponding to each of the protrusions.

[0006] Furthermore, a metal reinforcement grid is arranged inside the protective sleeve at a position corresponding to the outer side of the cavity, and the shape of the reinforcement grid is matched with the shape of the protective sleeve.

[0007] Furthermore, the connecting buckle body is formed by folding a rope in half and then braiding it.

[0008] Furthermore, after being folded in half, the two ends of the rope are intertwined and braided to form the diamond knot.

[0009] Furthermore, after being folded in half, the middle parts of the rope are woven together to form a single-strand force-bearing portion, and the protective sleeve is sleeved on the outside of the force-bearing portion.

[0010] Furthermore, a hole is provided on one strand of the folded end of the rope, and the other strand of the rope is inserted along the hole. After the folded strands of the rope are interlaced with each other to form the rope buckle, and the diamond knot is inserted along the eye of the rope buckle.

[0011] Furthermore, the material of the connecting buckle body is ultra-high molecular weight polyethylene fiber.

[0012] The above-mentioned technical scheme of the utility model has the following beneficial effects: the utility model arranges a protective sleeve on the connecting buckle body, and the arrangement of the protrusion and the cavity on the protective sleeve can produce better deformation when subjected to pulling force. In this way, the protective sleeve can be fully deformed when subjected to external force, effectively dispersing the extrusion force borne by the protective sleeve, thereby improving the performance of the outer sleeve itself, and further better protecting the connecting buckle body inside it, preventing the connecting buckle body from excessive wear, and greatly extending the service life of the connecting buckle body.

[0016] In order to more clearly understand the above-mentioned purposes, features and advantages of the utility model, the utility model is further described in detail below in conjunction with the accompanying drawings and specific implementation methods. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0017] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the protection scope of the present invention is not limited to the specific embodiments disclosed below.

[0018] like Figure 1-3 As shown, the explosion-proof connecting buckle described in this embodiment includes a connecting buckle body 1, a diamond knot 2 is provided at one end of the connecting buckle body 1, a rope buckle 3 is provided at the other end of the connecting buckle body 1, and a protective cover 4 is provided in the middle of the connecting buckle body 1;

[0019] The outer side of the protective sleeve 4 is evenly provided with a plurality of protrusions 41 along the circumferential direction, and the inner side of the protective sleeve 4 is provided with cavities 42 at positions corresponding to the protrusions 41 .

[0020] A metal reinforcement grid 5 is arranged inside the protective sleeve 4 at a position corresponding to the outer side of the cavity 42. The shape of the reinforcement grid 5 matches the shape of the outer sleeve 4. The reinforcement grid 5 improves the strength of the protective sleeve 4 and can improve its anti-damage ability.

[0021] The connecting buckle body 1 is formed by folding a rope in half and then braiding it.

[0022] After being folded in half, the two ends of the rope are intertwined and braided to form a diamond knot 2.

[0023] The middle parts of the folded rope are woven together to form a single-strand stress-bearing portion, and the protective sleeve 4 is arranged on the outside of the stress-bearing portion.

[0024] A through hole 11 is arranged on one strand of the folded end of the rope, and the other strand of the rope is inserted along the through hole 11 . After the two strands of the folded rope are interlaced with each other to form a rope buckle 3 , and the diamond knot 2 is inserted along the eyelet 31 of the rope buckle 3 .
