Referring to fig. 1 and 2, the present invention discloses a hollow wall winding pipe connection structure including a sealing member 200 and at least two pipe members 100.

The pipe fitting 100 comprises an outer wall 110 and an inner wall 120 which are equal in length, the front end of the inner wall 120 protrudes out of the front end of the outer wall 110 along the axial direction of the pipe fitting 100, a side wall 130 is spirally wound around the axis of the pipe fitting 100 between the outer wall 110 and the inner wall 120, the side wall 130 extends from the front end of the inner wall 120 to the rear end of the outer wall 110, any two pipe fittings 100 can be butted front and back through spiral matching between the side walls 130, the outer walls 110 of the two butted pipe fittings 100 are mutually jointed, and a sealing element 200 is sleeved on the periphery of the butted position of the two pipe fittings 100 and used for sealing the butted position and fixedly connecting the two pipe fittings 100.

It can be understood that, during the connection, the two pipe fittings 100 are oppositely arranged end to end, then the two pipe fittings 100 are reversely rotated and close to each other, so that the two side walls 130 are spirally matched with each other until the outer walls 110 of the two pipe fittings 100 are mutually attached to complete the butt joint, and finally, the sealing element 200 is sleeved on the periphery of the butt joint position to complete the sealing and the connection of any two pipe fittings 100. The connecting structure of the hollow wall winding pipe can complete the butt joint of the two pipe fittings 100 only through a simple spiral butt joint mode, is convenient and quick, and the sealing element 200 sleeved on the periphery of the butt joint position can play a role in sealing to prevent the water leakage problem at the joint. In addition, because the lengths of the outer wall 110 and the inner wall 120 of the pipe 100 are equal, and the outer walls 110 of the two butted pipe 100 are attached to each other, the inner walls 120 of the two butted pipe 100 are also attached to each other, and water leakage at the joint can be further prevented.

Referring to fig. 1, in some embodiments of the present invention, the sidewalls 130 of the two pipes 100 are engaged with each other at the screw fitting, and when the two pipes 100 are connected, the engaged sidewalls 130 can reinforce the strength of the connection. Specifically, when the joint of the two pipes 100 is subjected to a force in the radial direction of the pipes 100, the sidewalls 130 inside the two pipes 100 may interact with each other, preventing the outer wall 110 and the inner wall 120 of the pipes 100 from being separated, and thus preventing the joint of the pipes 100 from being damaged. In addition, when the pipe 100 is transported or lifted, the pipe 100 may bend, and when the joint of the two pipes 100 is subjected to a bending force, the two side walls 130 attached to each other may cooperate with the two inner walls 120 attached to each other or the two outer walls 130 attached to each other to resist the bending force, which may effectively prevent the joint of the pipes 100 from being broken due to excessive deformation. The sidewalls 130, which are attached to each other, can provide a good guide for the connection of the two pipes 100.

Further, referring to fig. 1, in some embodiments of the present invention, the heights of the front and rear portions of the sidewall 130 in the radial direction of the pipe member 100 are smaller than the height of the middle portion of the sidewall 130 in the radial direction of the pipe member 100. In the process of screwing the side walls 130 of the two pipes 100, friction is generated at the joint of the outer end surfaces of the side walls 130 and the inner side of the outer wall 110 or the outer side of the inner wall 120, when the heights of the front and the rear parts of the side walls 130 along the radial direction of the pipe 100 are smaller than the height of the middle part of the side walls 130 along the radial direction of the pipe 100, the friction force in the process of connecting the two pipes 100 is reduced, in addition, the area of the two side walls 130 which are mutually attached is reduced, the friction force in the process of mutually screwing the two side walls 130 is also reduced, and the connection of the pipes 100 is facilitated.

Referring to fig. 1, in some embodiments of the present invention, the length of the sealing member 200 is greater than the length of the two adjacent pipe elements 100 that are spirally fitted in the axial direction, so that the strength of the joint between the two pipe elements 100 is strengthened and the joint is prevented from bending.

In some embodiments of the utility model, the seal 200 may be a heat shrink sleeve or an electro-thermal tape. The heat-shrinkable sleeve is widely used for sealing and insulating the joint of the pipelines, can be radially shrunk when being heated and installed, meanwhile, the inner composite glue layer can be melted and tightly coated on the joint of the two pipelines 100, a firm anticorrosive coating is formed outside the pipelines 100, and the heat-shrinkable sleeve has excellent wear resistance, corrosion resistance and impact resistance. In addition, when the electric heating melting belt is connected with the pipe fitting 100 in an electrified way, a molten substance can be formed between the electric heating melting belt and the pipe fitting 100, molecules can mutually permeate and diffuse, so that a firm combination body can be formed after the electric heating melting belt is cooled, the electric heating melting belt can be firmly connected with the pipe fitting 100, and the tensile strength can be improved.

Referring to fig. 2, in some embodiments of the present invention, the sidewall 130 is perpendicular to the inner wall 120 in any plane where the axis of the inner wall 120 is located, and when the pipe 100 is subjected to the radial pressing force, the sidewall 130 perpendicular to the inner wall 120 can support the pipe 100 to the maximum extent, which is beneficial to prevent the pipe 100 from deforming.

Referring to fig. 1, in some embodiments of the present invention, the number of helical fitting turns of the side walls 130 of the two pipe elements 100 is at least two, and the larger the number of helical fitting turns between the two side walls 130, the larger the contact area of the two pipe elements 100 fitting each other, and the better the support effect between each other.

In some embodiments of the utility model, both end surfaces of the outer wall 110 and both end surfaces of the inner wall 120 are perpendicular to the axis of the tube 100. The end faces of the outer walls 110 and the end faces of the inner walls 120 perpendicular to the axis of the pipe fitting 100 can be better attached to each other in butt joint, and when the pipe fitting 100 is subjected to axial acting force, the end faces of the two outer walls 110 and the end faces of the two inner walls 120 can be abutted against each other, so that the tendency of movement is avoided, and the strength of the joint of the pipe fitting 100 can be further enhanced.

The embodiments of the present invention have been described in detail with reference to the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made within the knowledge of those skilled in the art without departing from the gist of the present invention.
