Description

Technical Field

[0001] This utility model relates to the field of automotive anti-skid chains, and in particular to an automotive anti-skid chain connection structure. Background Technology

[0002] When driving on complex road surfaces such as ice, snow, and mud, snow chains are a key component to ensure driving safety. As the core connecting part of the snow chain, the performance of the connector directly determines the assembly stability and reliability of the snow chain. Existing snow chain connectors generally suffer from the problem of non-adjustable tightness or inconvenient adjustment.

[0003] A new solution is proposed to address this problem. Summary of the Invention

[0004] To address the shortcomings of existing technologies, the purpose of this utility model is to provide a car anti-skid chain connection structure that simplifies adjustment without disassembly, improves connection stability, and ensures driving safety.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a car anti-skid chain connection structure, including a main connecting seat, a bidirectional locking assembly movably connected to the main connecting seat, a set of connecting assemblies and connecting hooks arranged symmetrically, the main connecting seat having a first connecting hole and a second connecting hole through both ends, the bidirectional locking assembly including a first adjusting rod and a second adjusting rod arranged symmetrically on both sides of the main connecting seat and threadedly connected to the main connecting seat, the connecting assembly including an inner ring, an outer ring and a connecting ball disposed between the inner ring and the outer ring, the ends of the first adjusting rod and the second adjusting rod away from the main connecting seat being fixedly connected to the inner ring respectively, and the outer ring being fixedly connected to the connecting hook.

[0006] By adopting the above technical solution, during use, one end of the first and second adjusting rods is rotated into the adjusting cavity inside the main connecting seat through a threaded connection, and the abutment is connected to the first and second adjusting rods respectively. When it is necessary to adjust the tightness, the first and second adjusting rods can be adjusted simultaneously or sequentially with the assistance of the multi-foot adjusting ring. The positions of the first and second adjusting rods can also be adjusted individually. During adjustment, the connecting hooks on both sides are connected to the car anti-skid main chain. By setting the connecting components, the first and second adjusting rods can be rotated relative to the connecting hooks for adjustment, which simplifies the adjustment without disassembly, improves the convenience of adjustment, and maintains the integrity of the connection structure.

[0007] The present invention is further configured such that: the main connecting seat is hollow and has an adjustment cavity, and the ends of the first and second adjusting rods located in the adjustment cavity are both threadedly connected to abutments.

[0008] By adopting the above technical solution, the abutment fixedly connected to one end of the first adjusting rod and the second adjusting rod at the adjusting cavity is used to constrain the adjustment position of the first adjusting rod and the second adjusting rod, and the abutment is threadedly connected to the first adjusting rod and the second adjusting rod respectively, which facilitates the disassembly and replacement of the first adjusting rod and the second adjusting rod.

[0009] The present invention is further configured such that: a multi-foot adjusting ring is fixedly connected to the outside of both the first adjusting rod and the second adjusting rod.

[0010] By adopting the above technical solution, the multi-leg adjustment ring is more convenient to adjust than the circular ring.

[0011] The present invention is further configured such that: an extension post is fixedly connected to the outer ring, and the bottom of the connecting hook is welded to the extension post.

[0012] In summary, this utility model has the following beneficial effects:

[0013] 1. The adjustment operation is convenient and does not require disassembly. During adjustment, rotating the multi-foot adjustment ring drives the first and second adjustment rods to rotate, thereby adjusting the distance between the first and second adjustment rods and the main connecting seat to achieve tightness adjustment.

[0014] 2. High connection strength and good stability. Attached Figure Description
