Description

Technical Field

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

[0002] High-strength, pressure-resistant PVC pipe is a pipe material commonly used in construction, water supply and drainage, industry and other fields. It uses polyvinyl chloride (PVC) as the main raw material and is processed through a special process to have strong pressure resistance and high corrosion resistance. In order to improve its adaptability, a freely rotatable structure is designed so that the pipe can flexibly respond to changes in the external environment during installation and use, avoiding damage to the pipe due to uneven force.

[0003] However, in actual use, the following deficiencies still exist, such as: existing PVC pipes, PVC pipes are not easy to rotate freely and are fixed. In complex or narrow installation environments, if the PVC pipes cannot rotate freely, the difficulty and time of installation will increase, which may lead to increased installation costs and may also cause delays in construction progress. When fixed PVC pipes need to be repaired or replaced, the operation will become difficult. For example, when impurities in the pipe need to be cleaned, if the pipe cannot rotate, part of the pipe may need to be disassembled for cleaning, which not only increases the maintenance workload, but may also cause unnecessary damage to the pipe system.

[0004] Therefore, the utility model proposes a freely rotatable high-strength compression-resistant PVC pipe to solve the above problems. Utility Model Content

[0028] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0030] like Figure 1-Figure 3 As shown, the rotation fixing assembly 3 includes a tooth groove 31, a tooth block 32, a support block 33 and a rotating shaft 37. A damping rod 34 is fixedly connected to the support block 33, and a telescopic spring 35 is provided on the damping rod 34. The other end of the damping rod 34 is fixedly connected to a first fixing block 36. A clamp 38 is rotatably connected to the rotating shaft 37. A second fixing block 39 is fixedly connected to the clamp 38. A first bolt 310 is threadedly connected to the second fixing block 39. A limiting plate 311 is fixedly connected to the limiting plate 311. A second bolt 312 is threadedly connected to the limiting plate 311. The operator first places the straight pipe 1 and the bent pipe 2 in the clamp 38, and then tightens Tighten the first bolt 310 so that the clamp 38 can limit the straight pipe 1 and the curved pipe 2. Then, the operator rotates the straight pipe 1 and the curved pipe 2 to the desired angle, and then screws the second bolt 312 into the first fixing block 36 to fix the angle of the straight pipe 1 and the curved pipe 2 to prevent rotation therebetween. Through the cooperation of the damping rod 34 and the telescopic spring 35, this device can play a buffering role between the straight pipe 1 and the curved pipe 2, making the piping system more flexible and adaptable to different installation requirements. At the same time, it also provides the necessary stability and durability, thereby solving the technical problem of the PVC pipe being able to freely rotate and be fixed.

[0031] The above solution still has the problem that the straight pipe 1 and the curved pipe 2 cannot meet the pipe pressure resistance when subjected to external force, such as Figure 1 As shown: the straight pipe 1 is arranged in the clamp 38, and the bent pipe 2 is arranged in the clamp 38. Since the straight pipe 1 is arranged in the clamp 38, and the bent pipe 2 is arranged in the clamp 38, the clamp 38 can connect the straight pipe 1 and the bent pipe 2 and restrict them in the clamp 38;

[0032] like Figure 1-Figure 3As shown, the tooth groove 31 is opened on the straight pipe 1, the tooth block 32 is fixedly connected to the curved pipe 2, and the tooth groove 31 and the tooth block 32 are engaged. Since the tooth groove 31 is opened on the straight pipe 1, the tooth block 32 is fixedly connected to the curved pipe 2, and the tooth groove 31 and the tooth block 32 are engaged, the tooth groove 31 and the tooth block 32 can limit the rotation of the straight pipe 1 and the curved pipe 2 when they rotate, and can play a role in fine-tuning the rotation angle to prevent the rotation angle from being too large and affecting the operation accuracy.

The pressure-resistant component 4 includes a support ring 41. The straight pipe 1 and the curved pipe 2 are fixedly connected with the support ring 41. The straight pipe 1 and the curved pipe 2 are fixedly connected with a reinforcing rib 42. Since the straight pipe 1 and the curved pipe 2 are both provided with the support ring 41 and the reinforcing rib 42, the support ring 41 and the reinforcing rib 42 can provide high-strength support for the straight pipe 1 and the curved pipe 2, thereby preventing damage to the straight pipe 1 and the curved pipe 2 due to external forces.

[0034] Working principle:

[0035] like Figures 1-4 As shown, the operator first places the straight pipe 1 and the curved pipe 2 in the clamp 38, and then tightens the first bolt 310 so that the clamp 38 can limit the straight pipe 1 and the curved pipe 2. Next, the operator rotates the straight pipe 1 and the curved pipe 2 to the desired angle, and then screws the second bolt 312 into the first fixing block 36 to fix the angle of the straight pipe 1 and the curved pipe 2 to prevent rotation therebetween. Through the cooperation of the damping rod 34 and the telescopic spring 35, this device can play a buffering role between the straight pipe 1 and the curved pipe 2, making the piping system more flexible and adaptable to different installation requirements. At the same time, it also provides the necessary stability and durability. Since support rings 41 and reinforcement ribs 42 are provided in the straight pipe 1 and the curved pipe 2, the support rings 41 and reinforcement ribs 42 can provide high-strength support for the straight pipe 1 and the curved pipe 2, preventing damage to the straight pipe 1 and the curved pipe 2 due to external forces.
