Embodiment 1

[0021] See Figure 1-5 This embodiment provides a PVC corrugated pipe with adjustable rigidity, including a PVC corrugated pipe 1. One end of the PVC corrugated pipe 1 is connected with a first connector 2, and the other end of the PVC corrugated pipe 1 is connected with a second connector 3. An inner tube 4 is installed inside the PVC corrugated pipe 1, one side of the inner tube 4 is connected with an inner tube connector 13, and the inner wall of the first connector 2 and the outer wall of the second connector 3 are both provided with a first thread 5 , One side of the first thread 5 and the outer wall of the inner pipe connector 13 are both provided with a second thread 6, the inner wall of the PVC corrugated pipe 1 is equipped with a guide rail 7, and the guide rail 7 is embedded with a slider 8, a slider 8 and an inner wall The tubes 4 are connected by a shock-absorbing spring 11, a support column 12 is installed in the middle of the shock-absorbing spring 11, one end of ...

Embodiment 2

[0024] See Figure 1-5 , A further improvement is made on the basis of Example 1: The outer wall of the PVC corrugated pipe 1 is coated with an anticorrosive coating, which is a phenolic epoxy coating, which is convenient to increase the service time of the PVC corrugated pipe 1.

[0025] Among them, the surface of the shock-absorbing spring 11 is coated with an anti-rust agent, which is convenient to prevent oxidation of the shock-absorbing spring 11 for a long time, and improve its use time. The surface of the limit block 9 is provided with anti-skid patterns, and the limit block 9 Anti-static particles are embedded in the inside to prevent slipping and static electricity when the limit block 9 is operated.

Abstract

The invention discloses an adjustable rigid PVC (polyvinyl chloride) bellows. The adjustable rigid PVC bellows comprising a PVC bellows is characterized in that one end of the PVC bellows is connectedwith a first connector, while the other end of the PVC bellows is connected with a second connector; an inner tube with one side connected with an inner tube connector is mounted inside the PVC bellows; a guide rail with the inner portion embedded with a slider is mounted on the inner wall of the PVC bellows; a slider and the inner tube are connected through a damping spring; a support column isinstalled in the middle of the damping spring. The adjustable rigid PVC bellows has the advantages of facilitating the connection and installation between PVC bellows through external and internal threads, solving the problems of difficulty in installation between pipes and affecting construction efficiency, allowing the inner tube to be expanded and contracted easily with the arrangement of the guide rail and the slider, guaranteeing rigidity of the PVC bellows to be easily changed according to the environment with the damping spring disposed between the slider and the inner tube, and effectively solving the technical problem of inconvenient adjustment of the PVC bellows.

Description

Technical field [0001] The invention relates to the technical field of PVC corrugated pipes, in particular to a PVC corrugated pipe with adjustable rigidity. Background technique [0002] PVC corrugated pipe is made of hard polyvinyl chloride as the main raw material. PVC double-wall corrugated pipe is extruded from the inside and outside, and formed at one time. The inner wall is smooth and the outer wall is trapezoidal corrugated. The inner and outer walls are sandwiched by hollow plastic pipe . [0003] In the technical field of PVC corrugated pipes, PVC corrugated pipes are mostly used in media transportation. The existing PVC corrugated pipes are difficult to install between pipes, which affects construction efficiency and cannot adjust the rigidity of PVC corrugated pipes. Summary of the invention [0004] The purpose of the present invention is to provide a PVC corrugated pipe with adjustable rigidity, so as to solve the problem of difficulty in installation between the PVC ...
