Description

Technical Field

[0001] The utility model relates to the technical field of high-strength and pressure-resistant PVC pipes, in particular to a high-strength and pressure-resistant PVC pipe. Background Art

[0002] PVC pipes are made of sanitary-grade polyvinyl chloride resin as the main raw material, with a certain amount of stabilizers, lubricants, fillers, color enhancers, etc. added, and are extruded by a plastic extruder and injection molded by an injection molding machine.

[0003] For example, a reinforced PVC pipe with the announcement number "CN111006077A" has a reinforcing layer that is a metal mesh layer. The PVC inner pipe, the metal mesh layer and the PVC outer pipe are an integrated structure. The inner surface of the PVC inner pipe is provided with an anti-corrosion layer, and the outside of the PVC outer pipe is provided with a protective layer. The structure is simple. By adopting the structure of the present invention, the overall strength of the PVC pipe can be greatly improved, so that it has higher strength and avoids rupture during use, thereby greatly extending its service life. However, the PVC pipe is generally longer and hollow inside during use. When the PVC pipe is subjected to pressure during transportation and installation, it will deform, making the PVC pipe unusable. In addition, the strength of the PVC pipe is poor, which shortens the service life of the PVC pipe. Utility Model Content

[0004] The utility model aims to solve the problem that the strength of PVC pipes is poor and the service life of the PVC pipes is shortened, and proposes a high-strength and pressure-resistant PVC pipe.

[0005] To achieve the above objectives, the present invention provides the following technical solutions:

[0006] A high-strength, pressure-resistant PVC pipe is designed, comprising a straight pipe and a sleeve, wherein the front end of the outer wall of the straight pipe is fixedly connected to the rear of the inner wall of the sleeve, the inner wall of the straight pipe is connected to a supporting structure, and the supporting structure comprises a first circular ring and a straight plate, the outer wall of the first circular ring is fixedly connected to the front end of the inner wall of the straight pipe, the rear end face of the first circular ring is fixedly connected to the front faces of multiple straight plates, and the rear end faces of the multiple straight plates are all fixedly connected to a second circular ring.

[0007] Preferably, the outer wall of the second circular ring is fixedly connected to the rear of the inner wall of the straight tube.

[0008] Preferably, the outer walls of the plurality of straight plates are fixedly connected to the inner wall of the straight tube.

[0009] Preferably, a gasket is fixed to the front end of the inner wall of the sleeve.

[0010] Preferably, square plates are fixedly connected to the front and rear sides of the outer wall of the straight tube respectively.

[0011] Preferably, the outer walls of the two square plates are respectively processed with grooves.

[0012] The utility model proposes a high-strength and pressure-resistant PVC pipe, which has the beneficial effect of: through the first circular ring and the second circular ring in the support structure, multiple straight plates are stably arranged on the inner wall of the straight pipe when the straight pipe is in use, thereby achieving thickened support of the inner wall of the straight pipe. The straight plates of multiple devices improve the strength of the straight pipe, which can prevent the straight pipe from being deformed under pressure, thereby improving the strength of the PVC and ensuring the service life of the PVC pipe.

[0018] The present invention will be further described below with reference to the accompanying drawings:

[0019] Example 1:

[0020] See also Figure 1-4 : In this embodiment, a high-strength and pressure-resistant PVC pipe includes a straight pipe 1 and a sleeve 3. The front end of the outer wall of the straight pipe 1 is fixedly connected to the rear of the inner wall of the sleeve 3. The straight pipe 1 is a PVC pipe. The inner wall of the straight pipe 1 is connected to a support structure 2. The support structure 2 includes a first circular ring 201 and a straight plate 202. The outer wall of the first circular ring 201 is fixedly connected to the front end of the inner wall of the straight pipe 1, and the rear end face of the first circular ring 201 is fixedly connected to the front faces of multiple straight plates 202. The rear ends of the multiple straight plates 202 are all fixedly connected to second circular rings 203. The outer wall of the second circular ring 203 is fixedly connected to the rear of the inner wall of the straight pipe 1. The outer walls of the multiple straight plates 202 are all fixedly connected to the inner wall of the straight pipe 1. The first circular ring 201, the straight plate 202, and the second circular ring 203 play a role in reinforcing and supporting the straight pipe 1.

[0021] By using the first circular ring 201 and the second circular ring 203 in the support structure 2, multiple straight plates 202 are stably arranged on the inner wall of the straight pipe 1, thereby achieving thickened support of the inner wall of the straight pipe 1. The straight plates 202 of multiple devices improve the strength of the straight pipe 1, which can prevent the straight pipe 1 from being deformed under pressure, improve the strength of the PVC, and ensure the service life of the PVC pipe.

[0022] A gasket 4 is fixed to the front end of the inner wall of the sleeve 3. The gasket 4 is made of rubber. Square plates 5 are fixed to the front and back sides of the outer wall of the straight tube 1. The outer walls of the two square plates 5 are respectively processed with grooves 6.

[0023] Working principle:

[0024] PVC pipe installation:

[0025] The rear of the outer wall of the straight tube 1 is plugged into the inner wall of the sleeve 3 in front of the outer wall of the second straight tube 1. At this time, the gasket 4 at the front end of the inner wall of the sleeve 3 can frictionally connect the sleeve 3 and the straight tube 1 through its own rubber material to complete the docking of the straight tubes 1.

[0026] PVC pipes are placed overlappingly:

[0027] The plurality of square plates 5 on the outer wall of the straight tube 1 are processed, and then the strap is wrapped around the groove 6 on the outer wall of the square plate 5 so that the strap is sunk into the plurality of grooves 6, thereby fixing the plurality of square plates 5 and the straight tube 1.

[0028] PVC pipe strength support:

[0029] When the straight pipe 1 is in use, the first ring 201 cooperates with the second ring 203 to stably arrange multiple straight plates 202 on the inner wall of the straight pipe 1, thereby achieving thickened support of the inner wall of the straight pipe 1. The straight plates 202 of multiple devices improve the strength of the straight pipe 1 and can prevent the straight pipe 1 from being deformed under pressure.

[0030] Example 2:

[0031] See also Figure 1-4 : In this embodiment, a high-strength and pressure-resistant PVC pipe also includes a collar 7, the inner wall of the collar 7 is fixedly connected to the rear of the outer wall of the straight pipe 1.

[0032] Working principle:

[0033] After the two straight tubes 1 are butted together, the end of the straight tube 1 that contacts the sleeve 3 will fit into the outer wall of the collar 7 , and the collar 7 can prevent the two straight tubes 1 from being excessively plugged in.

[0034] While the present invention has been shown and described with reference to preferred embodiments, it will be understood by those skilled in the art that various changes in form and details may be made therein within the scope of the claims.
