Description

Technical Field

[0001] The utility model relates to the technical field of corrugated pipes, in particular to an impact-resistant spiral corrugated pipe. Background Art

[0002] In the field of pipeline engineering, spiral bellows are widely used in drainage, sewage, ventilation and other systems due to their unique corrugated structure, good flexibility, scalability and pressure resistance. However, with the increasing complexity of the engineering environment, the impact resistance requirements for spiral bellows are also getting higher and higher. However, when traditional spiral bellows are subjected to external impact, their corrugated shells are prone to deformation or rupture, resulting in pipeline failure and posing safety hazards to the project. Therefore, we propose an impact-resistant spiral bellows to solve the above problems. Utility Model Content

[0003] The main purpose of the utility model is to provide an impact-resistant spiral corrugated pipe, which solves the problem that the corrugated shell of the traditional spiral corrugated pipe is easily deformed or broken when subjected to external impact, resulting in pipeline failure and posing a safety hazard to the project.

[0004] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0005] A shock-resistant spiral corrugated pipe comprises a corrugated pipe, wherein the corrugated pipe comprises a plastic inner pipe and a corrugated outer pipe, wherein the corrugated outer pipe is mounted on the outer side of the plastic inner pipe, an shock-resistant mechanism is mounted between the plastic inner pipe and the corrugated outer pipe, and the shock-resistant mechanism comprises a reinforcing block and a transmission block, wherein the reinforcing block is mounted inside the corrugated outer pipe, a supporting block is mounted on the outer side of the plastic inner pipe and at one end located inside the corrugated outer pipe, a buffer pad is mounted inside the supporting block, and the transmission block is mounted between the reinforcing block and the buffer pad.

[0006] Preferably, the reinforcement block is tightly fitted to the inner wall of the corrugated outer shell, and the reinforcement block is connected to the plastic inner tube.

[0007] Preferably, one end of the transmission block away from the buffer pad is in contact with the reinforcement block.

[0008] Preferably, a connecting block is installed at one end of the transmission block close to the buffer pad, and the connecting block is installed inside the buffer pad.

[0009] Compared with the prior art, the utility model has the following beneficial effects:

[0010] (1) In the utility model, the strength of the corrugated shell is increased by a reinforcing block, so that it can effectively resist deformation and rupture during the impact process. Then, the impact on the whole is buffered by the cooperation of the transmission block and the buffer pad. By dispersing and absorbing the impact energy, the damage caused to the corrugated tube by the impact is reduced. The overall strength can be improved, and the bellows has significant impact resistance, which is more convenient to use.

[0011] (2) In the utility model, the buffer pad is placed inside the support block to achieve the positioning of the buffer pad, which makes it easier for the transmission block to transmit the impact force to the inside of the buffer pad through the connecting block. The buffer pad then disperses and transmits the impact force to the inside of the plastic inner tube through the support block, thereby minimizing the damage caused by the impact to the corrugated tube and better protecting it.
