Description

Technical Field

[0001] This utility model relates to the field of rubber corrugated pipe technology, specifically a steel ring reinforced rubber corrugated pipe. Background Technology

[0002] Rubber corrugated pipes typically have a wavy shape, offering excellent flexibility to adapt to irregular expansion and contraction during pipeline operation or to absorb thermal deformation. However, ordinary rubber corrugated pipes have limited resistance to pressure and deformation under some complex working conditions, making them prone to damage. Against this backdrop, steel-ring-reinforced rubber corrugated pipes have emerged. Placing the steel ring on the outside of the corrugated pipe provides direct additional support. When the corrugated pipe is subjected to external compression, impact, or deformation due to internal pressure changes, the external steel ring, with its high strength and rigidity, effectively disperses the pressure, limits excessive deformation, and greatly enhances its pressure and impact resistance.

[0003] Traditional integral steel rings need to be inserted from the end of the bellows, and then positioned by the crests and troughs of the bellows. There is no reliable positioning between the steel ring and the bellows, and it is easy to slide along the axis under vibration conditions. Therefore, a steel ring reinforced rubber bellows is needed. Utility Model Content

An inner steel ring is embedded in the limiting groove. An outer steel ring is fitted on the outside of the rubber corrugated pipe body at a position corresponding to the inner steel ring. A screw is threaded through the outer steel ring. The screw is threaded to the inner steel ring through the rubber corrugated pipe body. A fixing block is fixedly connected to the end of the screw away from the rubber corrugated pipe body. A steel ring is fixedly connected to the outer steel ring along the length of the rubber corrugated pipe body. The steel ring is fitted on the outside of the rubber corrugated pipe body.

[0006] In use, the limiting groove allows the inner steel ring to be installed on the inner wall of the rubber corrugated pipe body, forming a continuous and smooth inner surface. Then, the outer steel ring is fitted onto the outside of the rubber corrugated pipe body at the corresponding position of the inner steel ring. The steel ring is then fitted onto the outside of the rubber corrugated pipe body. Finally, the outer steel ring and the inner steel ring are fixed by screws. The fixing block allows the operator to tighten the screws more flexibly. Through the cooperation of the above structures, the steel ring can be stably positioned, preventing it from slipping off. The steel ring can protect the rubber corrugated pipe body, effectively dispersing pressure, limiting excessive deformation of the rubber corrugated pipe body, and greatly enhancing its pressure resistance and impact resistance.

[0007] Optionally, the gap between the limiting groove and the inner steel ring is filled with waterproof adhesive for bonding and fixing.

[0013] Optionally, the outer wall of the inner steel ring is provided with a threaded hole that matches the screw.

[0014] By adopting the above technical solution, it is beneficial to achieve the connection between the screw and the inner steel ring.

[0015] Optionally, a total of four screws are provided, and the four screws are distributed in a ring shape along the circumference of the rubber corrugated pipe body.

[0016] By adopting the above technical solution, the robustness of the connection between the inner and outer steel rings is further improved.

[0017] Optionally, both the outer and inner steel rings are made of stainless steel.

[0018] By adopting the above technical solution, it is beneficial to improve the corrosion resistance of the outer and inner steel rings, thereby extending their service life.

[0019] Optionally, the inner diameter of the inner steel ring is adapted to the diameter of the opening of the rubber corrugated pipe body.

[0020] By adopting the above technical solution, the gap between the inner steel ring and the opening of the rubber corrugated pipe body can be reduced, thus preventing the inner steel ring from shaking.

[0021] Compared with the prior art, the beneficial effects of the technical solution of this application are as follows:

[0022] The technical solution of this application uses a limiting groove to install the inner steel ring on the inner wall of the rubber corrugated pipe body, forming a continuous and smooth inner surface. Then, the outer steel ring is fitted onto the outside of the rubber corrugated pipe body at the corresponding position of the inner steel ring, and the steel ring is fitted onto the outside of the rubber corrugated pipe body. The outer steel ring and the inner steel ring are then fixed by a screw. The fixing block allows the operator to tighten the screw more flexibly. Through the cooperation of the above structures, the steel ring can be stably positioned and will not slip off. Attached Figure Description
