Detailed Description

The technical solution in the present invention will be clearly and completely described below with reference to the drawings in the present invention, and it is obvious that the described utility model is only a part of the utility model rather than the whole utility model. Based on utility model provides a, all other utility model that the ordinary skilled person in the art obtained under the prerequisite of not making creative work all belong to the utility model discloses the scope of protection.

In the description of the present invention, it is to be understood that the terms "inside", "outside", and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, and are only for convenience of description and simplification of description, but do not indicate or imply that the referred device or element must have a specific orientation, be constructed and operated in a specific orientation, and thus, should not be construed as limiting the present invention.

Furthermore, in the description of the present invention, "a plurality" means at least two, e.g., two, three, etc., unless specifically limited otherwise.

Referring to fig. 1-5, the present invention provides a technical solution:

the utility model provides a high insulating glass fiber pipe, is equipped with interior stay tube 2 including leading core 1, leads 1 outside cover of core, and interior stay tube 2 outside is from interior to being equipped with insulating layer 3, glass fiber sleeve pipe 4 and outer inoxidizing coating 5 outward in proper order, and insulating layer 3 is become the tubulose by ceramic fibre pencil 31 spiral coiling, and glass fiber sleeve pipe 4 includes glass fiber weaving layer 41, and the inboard of glass fiber weaving layer 41 is equipped with hot melt adhesive layer 42, and the rule is equipped with a plurality of hot melt adhesive strips 51 in the 5 outer inoxidizing coatings.

In this embodiment, the outer diameter of the guide core 1 is smaller than or equal to the inner diameter of the inner support tube 2, so that the guide core 1 can be easily inserted into the inner support tube 2.

Particularly, the inner support tube 2 is preferably made of silicon rubber, and is flexible, firm, high-temperature resistant, oil-proof, water-proof and good in insulating property.

In this embodiment, the ceramic fiber bundle 31 is spirally wound on the outer side wall of the inner support tube 2, and the insulation property of the catheter can be effectively improved by the ceramic fiber bundle 31.

Further, the ceramic fiber strands 31 are lightweight, avoiding the weight of the conduit from being increased by thickening the wall of the conduit.

In this embodiment, the outer side wall of the hot melt adhesive layer 42 is fixed to the inner side wall of the glass fiber woven layer 41 by melting.

Further, the hot melt adhesive layer 42 is clamped between the glass fiber woven layer 41 and the insulating layer 3, and when the hot melt adhesive layer 42 is heated and melted, the hot melt adhesive layer can penetrate into the gap of the inner woven surface of the glass fiber woven layer 41 and the gap between the ceramic fiber wire bundles 31, so that the firmness of the inner structure of the catheter is improved, and the catheter can be used more and more firmly.
