Description

Technical Field

[0001] This utility model relates to the field of polyvinyl chloride corrugated pipe technology, specifically a polyvinyl chloride large-diameter corrugated pipe structure. Background Technology

[0002] Polyvinyl chloride (PVC) corrugated pipe is a type of pipe with a corrugated outer surface. PVC corrugated pipe has a wide range of applications and is commonly used in building drainage systems, municipal drainage systems, ventilation systems, cable protection, underground pipelines, and other fields. This type of corrugated pipe is made of polyvinyl chloride material and has excellent corrosion resistance and mechanical strength.

[0003] The existing PVC corrugated pipe has a relatively simple connection structure, poor connection strength, and poor sealing performance at the connection, which affects the normal transportation of fluids. Therefore, we propose a large-diameter PVC corrugated pipe structure. Utility Model Content

[0011] Preferably, a reinforcing ring is installed inside the corrugated pipe body near the outer ring, and a positioning groove is provided on the lower surface of the reinforcing rib at the position of the reinforcing ring, and the reinforcing ring is fitted into the positioning groove.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] 1. This utility model achieves a stable connection of PVC corrugated pipes by setting a connecting seat, locking rod, connector, buckle, and slot, thereby solving the problems of relatively simple docking structure, poor connection firmness, and poor sealing performance of existing PVC corrugated pipes, which affect the normal transportation of fluids. It improves the connection stability of PVC corrugated pipes, thus ensuring the normal transportation of fluids.

[0014] 2. This utility model achieves the effect of buffering and absorbing ground extrusion pressure by setting a support ring, support rod, spring, buffer ring and damping rubber, so as to solve the problem that existing PVC corrugated pipes are mostly buried underground, and the ground extrusion pressure is easily increased when vehicles are driving on the ground, which easily leads to damage to PVC corrugated pipes. It reduces the probability of damage to PVC corrugated pipes, thereby extending the service life of PVC corrugated pipes.

[0015] 3. By setting support rings, reinforcing ribs and reinforcing rings, this utility model achieves the effect of dispersing the pressure on the local area of ​​the corrugated pipe body, thereby solving the problem that the existing corrugated pipe body is subjected to large local pressure and cannot disperse the pressure, which easily leads to local damage to the corrugated pipe. This reduces the probability of damage to the corrugated pipe and thus improves the service life of PVC corrugated pipe. Attached Figure Description

[0022] The technical solution of the present invention is further described below with reference to the accompanying drawings and specific embodiments.

[0023] Example 1

[0024] like Figure 1 , Figure 2 and Figure 5 As shown, to achieve the above objectives, this utility model provides the following technical solution: a large-diameter corrugated pipe structure of polyvinyl chloride, including a corrugated pipe body 1 and a buckle 8. A connecting seat 3 is installed at one end of the corrugated pipe body 1, and a connector 4 is installed at the end of the corrugated pipe body 1 away from the connecting seat 3. A connecting groove 7 is provided inside the connecting seat 3, and the connector 4 is adapted to the connecting groove 7. A slot 20 is provided on the outer surface of the connector 4. A buckle 8 is installed on the inner surface of the connecting seat 3 through a moving groove 11. The buckle 8 can be snapped into the slot 20. A locking rod 12 is installed on the outer surface of the connecting seat 3 at the position of the moving groove 11. The locking rod 12 is sleeved inside the buckle 8. The locking rod 12 and the buckle 8 are connected by a threaded connection, which facilitates the movement of the buckle 8 by the locking rod 12. A sealing groove 10 is provided on one side of the connecting seat 3 near the inner surface. A sealing ring 9 is installed inside the sealing groove 10. The sealing ring 9 seals the connection.

[0025] The working principle of a large-diameter PVC corrugated pipe structure based on Embodiment 1 is as follows: After preparing multiple pipe bodies, when connecting them, insert the connector 4 at one end of the corrugated pipe body 1 into the connecting groove 7 at one end of another corrugated pipe body 1. Then rotate the locking rod 12, which drives the buckle 8 to move down and engage the buckle 8 in the slot 20. The buckle 8 then presses against the slot 20, thereby locking the connector 4 and the connecting seat 3, thus stably connecting multiple corrugated pipe bodies 1. The present invention can then be used to transport fluids. At this point, the workflow of the equipment is complete.

[0026] Example 2

[0027] like Figure 2-4As shown, the present invention proposes a large-diameter corrugated pipe structure for polyvinyl chloride. Compared with Embodiment 1, this embodiment further includes: an outer ring 5 on the outer surface of the corrugated pipe body 1, a support ring 14 installed at the bottom of the inner ring 5, a support rod 13 sleeved on the top of the support ring 14, a buffer ring 16 installed on the top of the support rod 13 inside the outer ring 5, a spring 17 installed on the outer surface of the support rod 13 at the gap between the buffer ring 16 and the support ring 14, and damping rubber 15 installed on both sides of the gap between the buffer ring 16 and the support ring 14. The spring 17 and the damping rubber 15 buffer and absorb the extrusion pressure, thereby protecting the present invention. A connecting rib 2 is provided on the outer surface of the corrugated pipe body 1 at the gap of the outer ring 5, and a reinforcing rib 18 is installed inside the connecting rib 2. The reinforcing rib 18 is connected to the support ring 14. A reinforcing ring 6 is installed inside the corrugated pipe body 1 on the side close to the outer ring 5. A positioning groove 19 is provided on the lower surface of the reinforcing rib 18 at the position of the reinforcing ring 6, and the reinforcing ring 6 is snapped into the positioning groove 19.

[0028] In this embodiment, during use, the outer ring 5 protects and supports the bellows body 1. When the bellows body 1 is subjected to compressive force, the compressive force compresses the buffer ring 16, thereby compressing the spring 17 and the damping rubber 15. The spring 17 and the damping rubber 15 buffer and absorb the compressive force, and at the same time transmit the pressure to the support ring 14. Through the action of the support ring 14 and the connecting rib 2, the pressure is transmitted to the reinforcing ring 6. The supporting force of the reinforcing ring 6 provides high-strength support for this utility model, thereby protecting the bellows body 1.

[0029] The above specific embodiments are only several preferred embodiments of the present invention. Based on the technical solutions of the present invention and the relevant inspirations of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above specific embodiments.
