Abstract

The utility model relates to an anti-sticking contracting casing pipe for a pipeline. The anti-sticking contracting casing pipe comprises a casing pipe body. A plurality of grooves are evenly formed in the inner wall face of the casing pipe body. The section of each groove is in a trapezoidal structure. A triangular tooth-shaped protrusion is formed between every two adjacent grooves. The section of the casing pipe body is of a circular structure. The anti-sticking contracting casing pipe has the advantages that the grooves are arrayed continuously, regularly and orderly in the inner wall of the casing pipe so that air can be discharged smoothly, the appearance is smooth and attractive, bad phenomena such as loose wrapping are avoided, reworking is of no need, one-time heating forming is achieved, manual cost and other cost are saved, when the casing pipe is used, after manually-worn protected objects such as a rubber pipe is assembled in a qualified mode, heating equipment is used for heating the casing pipe, the casing pipe is contracted on a protected object automatically after being heated, and the shape after contracting is basically the same as the shape of the protected object.

Description

The antiseized shrink sleeve of a kind of pipeline

Technical field

The utility model relates to weave cloth technology, relates in particular to the antiseized shrink sleeve of a kind of pipeline.

Background technique

Now, whole world insulation, the material such as heat insulation, wear-resisting are just towards integrated future development, for example, for on the vehicle of high speed operation and for the protection of automobile, locomotive water pipe and oil pipe, the material such as be used for preventing vehicle leakage of oil, leak, potential safety hazard for pre-anti-vehicle, existing shrink sleeve product internal surface is without groove, in heating process, inner air tube cannot be discharged, and causes heating rear formation bubble, affect outward appearance, cannot meet customer need, if again do over again and cause, can cause artificial waste.Therefore,, for above aspect, need to reasonably improve prior art.

Model utility content

For above defect, the antiseized shrink sleeve of pipeline that the utility model provides a kind of and has superior wear-resisting property, can prevent vehicle safety hidden danger, avoids pyrocondensation silk to scatter, be conducive to meet customer need, to solve many deficiencies of prior art.

For achieving the above object, the utility model is by the following technical solutions:

Use an antiseized shrink sleeve, comprise sleeve body, the internal face of described sleeve body is evenly offered some grooves, and this groove cross section is trapezium structure, forms a triangle dentation projection between every two adjacent grooves; Described sleeve body cross section is round structure.

Pipeline described in the utility model with the beneficial effect of antiseized shrink sleeve is: by shrink sleeve inwall being outputed to the groove of continuous regular marshalling, air can be discharged smoothly, smooth in appearance is attractive in appearance, without being coated the bad phenomenon such as not tight, without doing over again, a hot briquetting, saves artificial grade for cost; When product is used, manually through protected object, as rubber pipe etc., after assembling is qualified, use heating plant to the heating of this product, after this product is heated, be automatically contracted on protected article, the shape after contraction and protected object shape are basically identical.

Accompanying drawing explanation

With reference to the accompanying drawings the utility model is described in further detail below.

Fig. 1 is the section of structure of antiseized shrink sleeve for pipeline described in the utility model embodiment.

In figure:

1, sleeve body; 2, internal face; 3, groove.

Embodiment

As shown in Figure 1, the antiseized shrink sleeve of pipeline described in the utility model embodiment, comprise sleeve body 1, described sleeve body 1 cross section is that round structure and the internal face 2 that is positioned at this sleeve body 1 are evenly offered some grooves 3, this groove 3 is trapezium structure, forms a triangle dentation projection between every two adjacent grooves 3; When product is used, manually through protected object, as rubber pipe etc., after assembling is qualified, use heating plant to the heating of this product, after this product is heated, be automatically contracted on protected article, the shape after contraction and protected object shape are basically identical.

Above embodiment is more preferably embodiment a kind of of the utility model, and the common variation that those skilled in the art carry out within the scope of the technical program and replacing should be included in protection domain of the present utility model.

Claims

1. the antiseized shrink sleeve of pipeline, comprise sleeve body (1), it is characterized in that: the internal face (2) of described sleeve body (1) is evenly offered some grooves (3), this groove (3) cross section is trapezium structure, forms a triangle dentation projection between every two adjacent grooves (3).

2. the antiseized shrink sleeve of pipeline according to claim 1, is characterized in that: described sleeve body (1) cross section is round structure.
