AI Technical Summary
Existing cold shrink sleeves tend to twist when wrapping cable attachment components, and the wrapping is not uniform, resulting in uneven tightness.
A prefabricated sealed mud shrink sleeve is designed. By setting reinforcement rings and notches on the outer wall of the cooling tube and setting anti-slip blocks on the inner wall, friction is increased to prevent twisting, and at the same time, the elasticity of the reinforcement ring is used to ensure the wrapping is tight.
Through the design of reinforcement rings, notches and anti-slip blocks, the friction between the cold shrink sleeve and the surface of the cable accessories is increased to prevent twisting, and the tightness of the wrap is ensured through elastic stretching, which solves the problem of the tightness of the wrapping of the cold shrink sleeve.

Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of cold shrink sleeves, in particular to a prefabricated sealing adhesive cold shrink sleeve. Background Art
[0002] At present, cold shrink tubing is made of elastomeric materials, which are injection-vulcanized in the factory, and then expanded and lined with plastic spiral supports to form components of various cable accessories. Because it shrinks at room temperature by elastic retraction force, rather than using fire to heat and shrink like heat-shrinkable cable accessories, it is commonly known as cold-shrinkable cable accessories.
[0003] At present, the cold shrink tubing is wrapped around various cable accessory components by utilizing its shrinkage properties. After wrapping, there is no friction between the inner wall of the cold shrink tubing and the surface of the components on the various cable accessories, which can easily cause the cold shrink tubing to twist. Moreover, the cold shrink tubing needs to be tightened when wrapping to ensure the tightness of the wrapping. During the stretching process, different parts are prone to generate different forces, resulting in different tightness of the cold shrink tubing wrapping. Utility Model Content
