[0003] HPVC pipes protect cables by placing them inside and burying them underground. HPVC pipes buried underground need to have good pressure resistance. With the rapid development of modern pipeline engineering technology, especially in applications under high pressure, large flow and complex environmental conditions, although HPVC pipes have a certain pressure resistance, under extreme working conditions, the pressure on HPVC pipes will be different. Places with high pressure will be damaged over time, causing damage to internal cables. It is necessary to add pressure-resistant structures to HPVC pipes that are subject to high pressure to prevent HPVC pipes from being damaged due to pressure resistance.
[0004] In view of this, the utility model provides an enhanced pressure-resistant structure of an HPVC pipe. Utility Model Content

A groove is opened on the inner wall of the reinforcement ring, and a reinforcement plate for reinforcing the pipe is clamped inside the groove.
[0009] As a further improvement of the technical solution, four card slots are provided, and four card columns are fixedly installed on the outer surface of the reinforcement plate. The four card columns are clamped in the inside of the four card slots to install and fix the reinforcement plate.
[0010] As a further improvement of the technical solution, a plurality of wire holes are provided on the front side of the reinforcement plate, and the plurality of wire holes can be used to pass cables.
[0011] As a further improvement of the technical solution, the fixing assembly includes a tightening collar, and a fixing bolt for fixing the tightening collar is installed inside the tightening collar.
[0012] As a further improvement of the technical solution, the tightening collar is installed on the outer surface of the pipe body outside the reinforcement ring to fix the position of the reinforcement ring inside the pipe body.
[0013] Compared with the prior art, the utility model has the following beneficial effects:
[0014] 1. In the enhanced pressure-resistant structure of the HPVC pipe, when installing the enhanced pressure-resistant part of the pipe, the reinforcing plate can be slid into the four slots opened on the inner wall of the reinforcing ring through the four clamping columns fixed on the outer surface, so that the reinforcing plate is fixed inside the reinforcing ring. The multiple wire holes on the front of the reinforcing plate can pass the cables inside the pipe body. Then the reinforcing ring can slide into the inside of the pipe body through the multiple limit blocks installed on both sides, and the reinforcing ring is moved to the part where the pressure resistance needs to be strengthened.

[0024] First, the specific structure of the reinforcement component 2 is disclosed. The reinforcement component 2 includes a reinforcement ring 201 attached to the inner wall of the pipe body 1, and limit blocks 202 are fixedly installed on both sides of the reinforcement ring 201 to prevent the reinforcement ring 201 from rotating. A slot 203 is opened on the inner wall of the reinforcement ring 201, and a reinforcement plate 204 for reinforcing the pipe is clamped inside the slot 203.
[0025] There are four card slots 203, and four card posts 4 are fixedly installed on the outer surface of the reinforcing plate 204. The four card posts 4 are clamped in the four card slots 203 to install and fix the reinforcing plate 204. A plurality of wire holes 5 are opened on the front of the reinforcing plate 204, and the plurality of wire holes 5 can pass the cables.
[0026] When installing the reinforcement plate 204 to enhance the pressure resistance at the place where the pipe is under great pressure, the reinforcement plate 204 can be slidably installed into the four clamping grooves 203 opened on the inner wall of the reinforcement ring 201 through the four clamping columns 4 fixedly installed on the outer surface, so that the reinforcement plate 204 is fixed inside the reinforcement ring 201, and the multiple wire holes 5 on the front of the reinforcement plate 204 can pass the cables inside the pipe body 1, and then the reinforcement ring 201 can slide into the inside of the pipe body 1 through the multiple limit blocks 202 installed on the two sides, and move the reinforcement ring 201 to the place where the pressure resistance needs to be enhanced, and the outer wall of the reinforcement ring 201 is attached to the inner wall of the pipe body 1 to enhance the pressure resistance of the pipe body 1, and the outer surface of the reinforcement plate 204 clamped inside the reinforcement ring 201 is also attached to the inner wall of the reinforcement ring 201, so as to enhance the pressure resistance of the pipe body 1, so as to achieve the effect of enhancing the pressure resistance of the pipe body 1 at the place where the pipe is under great pressure.
