Abstract

The utility model relates to a flexible tube for delivering natural gas, coal gas or liquefied petroleum gas, etc. A tube with double structures is used as a basal body, an external appearance of the basal body is coated with a smooth surface layer, and combination surfaces among layers of a hose are made into convex-concave interphase structures. The hose has the advantages of smooth surface, easy cleaning, good flexibility of a hose body, further improved strength of the hose, extended service life, improved product quality, ageing process delaying. And discoloration preventing.

Description

Fuel hose

The utility model relates to a kind of flexible tube of transport gas, coal gas or liquefied petroleum gas (LPG) etc.

The at present indoor pipe that is used for being connected between gas source and cooking stove generally adopts polyvinyl chloride hose or rubber and plastic double layer construction pipe.Polyvinyl chloride hose is the single layer structure pipe of smooth surface, and tube surface can not sheltered evil people and countenance evil practices, and is easy to clean, but pliability is relatively poor, and compressive strength is not enough, influences working life.Rubber and plastic double layer construction pipe pliability is good, and quality of product, appearance luster etc. all increase, but is easy to deposit dust in the groove on the pipe superficies, and in case greasy filth and so on dirt is contaminated then be difficult to remove clean; In addition, inside and outside two interlayers of pipe are the contact of light face, bad adhesion during heat seal, and easily layering, quality is difficult for guaranteeing, can influences working life equally.

The purpose of this utility model is to avoid deficiency of the prior art, and provides a kind of surface easy to clean, and pliability is good, and the gas hose product that bonds firm.

Can take following technological scheme to realize purpose.With the double layer construction pipe is matrix, multiple with light surface layer in the matrix appearance, and the junction plane of each interlayer of flexible pipe is made the alternate shape structure of convex-concave.

In conjunction with the accompanying drawings, mode of execution is described in further detail the content of the technical program.

Accompanying drawing is a kind of structure section schematic representation of this gas hose

This gas hose is a matrix with the double layer construction pipe, and matrix can be a rubber and plastic double layer construction pipe, also can be the double layer construction pipe of other soft material or mutual combination, and this point and prior art are basic identical.Difference is, the one, also have light surface layer (1) in the matrix appearance, and promptly this gas hose is the three-decker pipe; It is good, smooth transparent that light surface layer adopts pvc material to be fabricated to, and the dust dirt on it etc. are removed easily, also can increase the stereoeffect of flexible pipe interlayer decorative pattern, can make the quality of product better, and appearance luster is bright-coloured changeable; The 2nd, the junction plane of each interlayer of flexible pipe is the alternate shape structure of convex-concave, to increase mutual area of contact, helps each layer and be bonded together more firmly after heat seal, forms integral body, improves hose quality, and protruding, the recessed shape of junction plane can be selected as one sees fit.

In the example, the junction plane between internal layer (3) and mesosphere (2) is the alternate structure of plum blossom shape convex-concave as shown in drawings; Mesosphere (2) and skin--the junction plane between light surface layer (1) is the alternate structure of flexuose convex-concave.Both be beneficial to each layer strong bond mutually, and be convenient to again make; Under light surface layer, also can be marked with the place of production, producer's register and other ad decoration pattern on the mesosphere, prolonged preservation.

The relative prior art of the utility model has following advantage:

1, hose surface is smooth, can not shelter evil people and countenance evil practices, and is easy to clean, also has three-dimensional decorative effect;

2, the body pliability is good, keeps the strong point of rubber plastic pipe;

3, each layer area of contact increases, and bonding firm, the intensity of flexible pipe further improves, and increases the service life, and improves quality of product.

4, can delay the aging of product, prevent to fade.

Claims

1, a kind of gas hose is a matrix with the double layer construction pipe, it is characterized in that: it has light surface layer (1) again in the matrix appearance, and the junction plane of each interlayer of flexible pipe is the alternate shape structure of convex-concave.

2, gas hose as claimed in claim 1 is characterized in that: the junction plane between the bilayer of matrix (2), (3) is the alternate structure of plum blossom shape convex-concave; Junction plane between matrix and light surface layer (1) is the alternate structure of flexuose convex-concave.
