Insulating sealing method of object unequal in diameter

An insulating sealing and non-equal-diameter technology, which is applied in the field of insulating sealing of diameter objects, can solve the problems that the non-equal-diameter cold shrinkable tube 20' cannot play the role of insulating and sealing, the sliding distance is large, and it falls off, so that it is not easy to slide and avoid cracking, good effect

Problems solved by technology

[0004] However, after the above-mentioned unequal-diameter cold-shrinkable tube 20' is inserted into the non-uniform-diameter object 10' and the cold-shrink sheath is shrunk onto the non-uniform-diameter object 10', the thick end 21' of the non-uniform-diameter cold-shrinkable tube 20' is The thick end of the cold shrinkable sheath will slide in the direction towards the thin end, and the longer the time, the greater the sliding distance or even fall off, which makes the non-equal diameter cold shrinkable tube 20' not able to play its proper role of insulation and sealing

Embodiment Construction

[0025] In order to describe the technical content, insulation and sealing method, purpose and effect of the present invention in detail, the following will be described in detail in conjunction with the implementation and accompanying drawings.

[0026] For ease of description, the two cold-shrinkable tubes in the present invention are called the first cold-shrinkable tube and the second cold-shrinkable tube respectively, and "first and second" are named for the sake of easy identification and description.

[0027] see figure 2 , image 3 with Figure 4 In the present invention, the non-equal-diameter object 10 refers to an object to be protected that is thicker at one end relative to the other end, including a thick end 11 and a thin end 12, such as a thicker cable at the connection. Here, the thickness of the non-equal-diameter object The end is the connection, and the thin end of the non-equal-diameter object is the cable.

[0028] The first cold shrinkable tube 20 is i...

Abstract

The invention discloses an insulating sealing method of an unequal-diameter object. The insulating sealing method includes the following steps that firstly, a tapered or frustum-shaped first shrink tube with a tapered surface shrinks at the thin end of the unequal-diameter object , the shrinking first shrink tube is close to the thick end of the unequal-diameter object, and the higher end of the tapered surface completely or nearly aligns with the surface of the thick end of the unequal-diameter object; then, a second shrink tube shrinks at the thick end of the unequal-diameter object and the first shrink tube so as to complete insulating sealing of the unequal-diameter object. Due to the adoption of the insulating sealing method of the unequal-diameter object, the problem of sliding caused by unequal outer diameters can be avoided, installment is simple, sliding does not happen easily, cracking caused by too large extension rate can be avoided, and a good insulating sealing effect is achieved.

Description

technical field [0001] The invention relates to an insulating and sealing method for objects, in particular to an insulating and sealing method for objects with non-equal diameters. Background technique [0002] The cold-shrinkable tube is made of elastomer material in the factory for injection vulcanization, and then expanded to form a cold-shrinkable sheath and lined with a spiral support to form various cable accessories or other accessories. When installing, put the cold shrinkable tube on the treated cable end or joint or other components, pull out the inner supporting support tube, and compress the cold shrinkable sheath on the cable or other components. [0003] see figure 1 , in response to the needs of non-uniform diameter objects 10' with thicker ends and thinner ends, people have developed non-uniform diameter cold-shrinkable tubes 20' with different thicknesses at both ends, that is, one end 21' of the non-uniform diameter cold-shrinkable tubes 20' is opposite...
