Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of plastic pipes. Background Art
[0002] The plastic pipe comprises a plastic pipe body, which is generally a single-layer structure. In the prior art, the plastic pipe body has no other supporting components. Such a plastic pipe has the disadvantages of poor pressure resistance and weak supporting capacity, which affects the use range and service life of the plastic pipe. Summary of the invention
[0003] The utility model aims to provide a composite plastic pipe with a built-in support spring, which has strong bearing capacity, wider application range and long service life, in view of the above shortcomings.
[0004] The technical solution of the utility model is achieved in this way. A composite plastic tube with a built-in support spring includes a plastic tube body, and the plastic tube body has an outer side surface. The characteristic is that the outer side surface of the plastic tube body has a spiral groove for winding the spring, and the groove is a first groove. A spring is installed in the first groove. The spring and the first groove are heat-sealed together. There is also an outer tube outside the plastic tube body to surround the plastic tube body.
[0005] Furthermore, the spring is formed by winding a steel wire, and the first groove has a structure that accommodates half of the cross section of the steel wire.
[0006] Furthermore, the cross section of the steel wire is:
[0007] Or a rectangular structure, the length direction of the rectangle is consistent with the length direction of the plastic pipe body;
[0008] or circular structures;
[0009] Or an elliptical structure, the major axis direction of the ellipse is consistent with the length direction of the plastic pipe body.
[0010] Furthermore, the outer covering pipe is formed by two pipe segments with semicircular arc cross sections buckled on the outside of the plastic pipe body.
[0011] Furthermore, the pipe segment has a groove that matches the outside of the steel wire cross section, and this groove is a second groove. The inner side of the pipe segment is in contact with or heat-sealed to the outside of the plastic pipe body.
[0012] Furthermore, a layer of heat-insulating material is sandwiched between the outer tube and the plastic tube body.
[0013] The beneficial effects of the utility model are as follows: such a plastic pipe has the advantages of strong bearing capacity, wider application range and long service life. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] The utility model is further described below in conjunction with the accompanying drawings.
[0022] As shown in the figure, a composite plastic tube with a built-in support spring includes a plastic tube body 1, and the plastic tube body has an outer side surface, wherein the outer side surface of the plastic tube body has a spiral groove for winding a spring, and the groove is a first groove 2, and a spring 3 is installed in the first groove, and the spring and the first groove are heat-sealed together, and an outer tube 4 is also provided outside the plastic tube body to surround the plastic tube body.
[0023] The utility model can achieve the purpose of the utility model because the spring is wound on the outer side surface of the plastic pipe body.
[0024] Furthermore, the spring is formed by winding a steel wire, and the first groove has a structure that can hold half of the cross section of the steel wire. Figure 1 , 2 , 3, 4, and 5.
[0025] Furthermore, the cross section of the steel wire is:
[0026] Or a rectangular structure, the length direction of the rectangle is consistent with the length direction of the plastic pipe body; Figure 2 As shown,
[0027] or circular structures; Figure 3 As shown,
[0028] Or an elliptical structure, the major axis direction of the ellipse is consistent with the length direction of the plastic pipe body, such as Figure 4 shown.
[0029] Furthermore, the outer tube is formed by buckling two semicircular arc-shaped tube segments on the outside of the plastic tube body. Figure 6 shown.
[0030] Furthermore, the pipe segment has a groove matching the outer surface of the steel wire cross section, which is the second groove 5, and the inner side of the pipe segment is in contact with or heat-sealed with the outer surface of the plastic pipe body. Figure 2 , 3 , as shown in Figure 4.
[0031] Furthermore, a layer of heat-insulating material 6 is sandwiched between the outer tube and the plastic tube body. Figure 5 , 6 shown.
[0032] The utility model is arranged in this way, and has a better heat preservation effect.
