Description

Technical Field

[0001] The utility model belongs to the technical field of cold shrink sleeves, and in particular relates to an anti-slip cold shrink sleeve. Background Art

[0002] The cold shrink tubing is an insulating sleeve that is pre-expanded on a support tube. When in use, you only need to pull out the core and use its cold shrinkage characteristics at room temperature to wrap the cable to achieve waterproof, moisture-proof and sealing effects. However, the existing technology is not perfect in optimizing the anti-slip performance of the cold shrink tubing.

[0003] Application number "CN201821316389.0" records "a new type of cold shrink sleeve, comprising an elastic rubber tube that can be cold-shrunk at room temperature, and a supporting core member for supporting the elastic rubber tube, wherein the supporting core member is prefabricated in the elastic rubber tube in a spiral tube shape, and a core rope for drawing is provided at the end of the supporting core member; a raised thread ring structure is added to the outer side of the elastic rubber tube, and the thread ring structure is arranged at equal intervals along the length direction of the outer side of the elastic rubber tube. The height of the annular protrusion is set to 0.5-3mm, the width of the annular protrusion is set to 1-5mm, the spacing between the annular protrusions is set to 0.5-4mm, and the total length of the thread ring structure is set to 30-500mm; the total length of the elastic rubber tube is set to 50-500mm, the port wall thickness is set to 0.3-5mm, and the inner diameter of the supporting core member is set to 15-120mm."

[0004] The above patent is based on a new type of cold shrink sleeve. When the cold shrink sleeve is hit or damaged by external impact, the threaded ring structure on the cold shrink sleeve can absorb the impact energy through its own deformation, achieve a buffering effect and protect the cable joint from damage. At the same time, due to the buffering effect of the threaded ring structure, the elastic rubber tube is not easy to break due to impact. The structural change is used to optimize the defects of the rubber material. At the same time, the cold shrink sleeve has good resilience and automatically shrinks and hugs the cable and joint. The diameter of the cold shrink sleeve is designed according to the size of the cable joint to be protected, which plays an overall waterproof sealing effect.

[0005] The above patent improves the cushioning property of the cold shrink tubing to achieve resistance to external impact and puncture, thereby improving its long-term reliable waterproof sealing protection for irregular cables in various environments. However, the above patent does not fully optimize the anti-slip performance of the cold shrink tubing, resulting in lower overall quality of the cold shrink tubing. Utility Model Content
