Abstract

The utility model discloses a tensile hosepipe, which comprises pipe main bodies (1) connected by pipe walls and at least one sleeve (2). A bearing rope (3) is arranged in the sleeve (2). The pipe walls of the utility model do not need to be strengthened aiming at the axial tension. The tensile hosepipe has the advantages of high tensile capacity, small minimum bending radius, good integral flexibility, simple manufacturing process, convenient installation and fixing and low cost.

Description

Anti-stretching hose

Technical field

The utility model relates to and a kind ofly is used to contain/conveyance fluid, semifluid or contain the flexible pipe of lead transmission of electric energy, be specifically related to a kind of flexible pipe with discrete axial pulling force bearing structure.

Background technique

One is used for containing also conveyance fluid (gas, liquid), semifluid (lotion) flexible pipe, contains the lead transmission of electric energy.The function that flexible pipe need possess comprises: contain in isolation features, the carrying gravity of object in external pressure, carrying pipeline and the pipeline, produce by gravity when carrying is hung each to component and carrying axial tension.

The structure of flexible pipe is varied at present, and one is the single tube structure of a body or the multitube structure that comprises many bodys, and one is single layer structure or multi-layer structure for the tube wall of body.But problems such as at the structure of these flexible pipes, when exceeding the bearing capacity of existing structure pipeline self structure for axial tension, tube wall lengthening deformation will take place, will break, the interlayer changing of the relative positions.In order to address this problem, the tube wall of body can adopt also more that the reinforced layer structure of high bearing capacity solves, but this mode can increase the minimum bending radius of pipeline, influences the application area of flexible pipe.

The model utility content

The utility model is at the shortcoming of above-mentioned prior art, the anti-stretching hose that provide that a kind of tube wall need not strengthen tube wall at axial tension, resistance to tension is good, minimum bending radius is little, overall flexibility is good, preparation process is simple, install and fix conveniently, cost is low.

In order to solve the problems of the technologies described above, the technical solution adopted in the utility model is: a kind of anti-stretching hose is characterized in that: it comprises tube body and at least one sleeve pipe that tube wall links to each other, and is provided with the carrying rope in the described sleeve pipe.

As further improvement of the utility model:

Described tube body and sleeve pipe are arranged side by side successively;

The inwall adhesion of described carrying rope and sleeve pipe is an one, is provided with the gap between the inwall of perhaps described carrying rope and sleeve pipe;

The two ends of described carrying rope are respectively equipped with fixing button;

It is made up of two tube bodies and a sleeve pipe, and two tube bodies are located at the sleeve pipe both sides respectively; Perhaps, it is made up of a tube body and a sleeve pipe.

The utlity model has following advantage: the utility model is restricted by the carrying in the sleeve pipe and is born the axial tension of flexible pipe, tube body only need carry its noumenon function and get final product, therefore tube wall does not need to strengthen structure, can not cause tube wall to be elongated when carrying bigger axial tension, have the advantage that resistance to tension is good, rigidity is little, weight is little, preparation process is simple, cost is low.Tube body of the present utility model and sleeve pipe can also be arranged side by side successively, make that anti-stretching hose still can be to edgewise bend when having a plurality of tube bodies and sleeve pipe, and minimum bending radius is little, overall flexibility good; In addition, the two ends of carrying rope also can be provided with fixing button respectively, make the carrying rope install and fix more convenient.

Embodiment

As depicted in figs. 1 and 2, the anti-stretching hose among first embodiment comprises tube body 1 and at least one sleeve pipe 2 that tube wall links to each other, and is provided with carrying rope 3 in the sleeve pipe 2.

Be provided with the gap between the inwall of carrying rope 3 and sleeve pipe 2 in the present embodiment, carrying rope 3 can slide in sleeve pipe 2, thus the anti-stretching hose of present embodiment be particularly useful for carrying restrict 3 and sleeve pipe 2 between the thermal expansion coefficient difference and the situation of flexible pipe horizontal fixed.Carrying rope 3 of the present utility model can be sub-thread or multiply structure, can adopt the preparation of metal or nonmetallic material, and carrying rope 3 is the wire of sub-thread structure in the present embodiment.

As shown in Figure 3 and Figure 4, the anti-stretching hose and first embodiment among the utility model second embodiment are basic identical, and its distinctive points is: carrying rope 3 is an one with the inwall adhesion of sleeve pipe 2.Therefore the anti-stretching hose of present embodiment is applicable to the close situation of thermal expansion coefficient between carrying rope 3 and the sleeve pipe 2, be particularly useful for the vertically fixing situation of flexible pipe, when flexible pipe vertically fixedly the time, axial tension can be by sleeve pipe 2 the inwall stepless action on carrying rope 3, thereby can avoid because unbalance stress causes the tube wall elongation or breaks.

As Fig. 5, Fig. 6 and shown in Figure 7, the anti-stretching hose among the utility model the 3rd embodiment is made up of two tube bodies 1 and a pipe box 2, and tube body 1 and pipe box 2 are arranged side by side successively, and two tube bodies 1 are located at pipe box 2 both sides respectively.Be provided with carrying rope 3 in the middle pipe box 2, be provided with the gap between the inwall of carrying rope 3 and sleeve pipe 2, carrying rope 3 can slide in sleeve pipe 2, the two ends of carrying rope 3 are respectively equipped with fixing button 31, therefore in fixing flexible pipe, can be quickly and easily with fixing button 31 fixing getting final product, in addition, the two ends of tube body 1 are equipped with hose coupling 11.

As Fig. 8 and shown in Figure 9, anti-stretching hose and the 3rd embodiment among the utility model the 4th embodiment are basic identical, and its distinctive points is: carrying rope 3 is an one with the inwall adhesion of pipe box 2.

The above only is a preferred implementation of the present utility model, and protection domain of the present utility model also not only is confined to the foregoing description, and all technological schemes that belongs under the utility model thinking all belong to protection domain of the present utility model.Should be understood that; for those skilled in the art; in the some improvements and modifications that do not break away under the utility model principle prerequisite; for example flexible pipe is provided with more tube body 1 and sleeve pipe 2; perhaps all tube bodies 1 and sleeve pipe 2 adopt fascicular texture; perhaps the tube wall of tube body 1 and sleeve pipe 2 adopts individual layer or composite structure; or change between tube body 1 and the tube body 1 or between tube body 1 and the sleeve pipe 2 or the distance between sleeve pipe 2 and the sleeve pipe 2 or the like, these improvements and modifications also should be considered as protection domain of the present utility model.
