Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of pipes, and particularly relates to a connecting piece for corrugated pipes.
Background Art
[0002] The raw material of the corrugated pipe is polyethylene. At present, polyethylene pipes on the market are usually straight pipes. When connecting pipes, hot melt connection installation is required. Especially in the construction area, a separate power cord needs to be pulled for hot melt operation. Especially when there is no power source at a long distance, equipment such as generators needs to be equipped, involving a large number of construction equipment and inconvenient installation. There is also a way to directly set socket and spigot at both ends of the corrugated pipe to realize the connection between corrugated pipes. In this way, after the corrugated pipe is prepared, socket and spigot need to be additionally processed at both ends of the corrugated pipe, which increases the manufacturing cost and process of the corrugated pipe.
Content of the Utility Model
[0003] To solve the above problems, the purpose of the utility model is to provide a connecting piece for corrugated pipes that can simply realize the connection between corrugated pipes.
[0004] To achieve the above purpose, the technical solution adopted by the utility model is: a connecting piece for corrugated pipes, including a connecting sleeve with openings at both ends. A limiting ring is fixed in the middle of the inner part of the connecting sleeve. The pipe ends of adjacent corrugated pipes are inserted into the inner part of the connecting sleeve. A sealing ring and an elastic anti-detachment ring are sleeved on the pipe ends of the corrugated pipes. The elastic anti-detachment ring is located outside the sealing ring. A clamping groove is arranged in the inner wall of the connecting sleeve. The outer end of the elastic anti-detachment ring is clamped in the clamping groove.
[0005] The connecting piece for corrugated pipes in the utility model is further set as: the sealing ring includes a sealing ring body and a clamping ring arranged on the inner wall of the sealing ring body. The clamping ring is clamped in the groove between adjacent corrugated bodies of the corrugated pipe.
[0006] The connecting piece for corrugated pipes in the utility model is further set as: the limiting ring includes an outer limiting part with a wider width and an inner limiting part with a narrower width. The end of the sealing ring abuts against the side wall of the outer limiting part. The inner limiting part is located between the corrugated bodies between the pipe ends of adjacent corrugated pipes.
[0007] The connecting piece for corrugated pipes in the utility model is further set as: the elastic anti-detachment ring is in a horn-shaped structure, including a clamping ring and an elastic anti-detachment body connected to the clamping ring and expanding outwards obliquely. The end of the elastic anti-detachment body is clamped in the clamping groove.
[0008] Compared with the prior art, the utility model has the following beneficial effects: For the above-mentioned connector of the corrugated pipe, the method of using a sealing ring plus an elastic anti-disengagement ring ensures the reliable connection between the two ends of adjacent corrugated pipes, not only realizes the sealed connection between adjacent pipe ends, but also is not easy to loosen.

Specific Embodiments
[0011] The following further describes in detail the above-mentioned connector of the corrugated pipe of the utility model through specific embodiments.
[0012] As shown in Figure 1 , a connector of a corrugated pipe includes a connecting sleeve 1 with openings at both ends. A limiting ring 2 is fixedly arranged in the middle of the interior of the connecting sleeve 1. The pipe ends of adjacent corrugated pipes 3 are inserted into the interior of the connecting sleeve 1. A sealing ring 4 and an elastic anti-disengagement ring 5 are sleeved on the pipe ends of the corrugated pipe 3. The elastic anti-disengagement ring 5 is located outside the sealing ring 4. A positioning groove 6 is arranged in the inner wall of the connecting sleeve 1. The outer end of the elastic anti-disengagement ring 5 is clamped in the positioning groove 6.
[0013] As a preferred solution, the sealing ring 4 includes a sealing ring 41 and a positioning ring 42 arranged on the inner wall of the sealing ring 41. The positioning ring 42 is clamped in the groove between adjacent corrugated bodies of the corrugated pipe 3.
[0014] As a preferred solution, the limiting ring 2 includes a relatively wide outer limiting part 21 and a relatively narrow inner limiting part 22. The end of the sealing ring 4 abuts against the side wall of the outer limiting part 21. The inner limiting part 22 is located between the corrugated bodies between the pipe ends of adjacent corrugated pipes 3.
[0015] As a preferred solution, the elastic anti-disengagement ring 5 has a horn-shaped structure, includes a positioning ring 51 and an elastic anti-disengagement body 52 connected to the positioning ring 51 and expanding outwardly and obliquely. The end of the elastic anti-disengagement body 52 is clamped in the positioning groove 6.
[0016] For the above-mentioned connector of the corrugated pipe 3, when connecting the corrugated pipes 3, the sealing ring 4 and the elastic anti-detachment ring 5 are sleeved on the pipe ends of the adjacent corrugated pipes 3, and then the pipe ends of the corrugated pipes 3 are respectively inserted into the connecting sleeve 1 from both sides. When the pipe ends of the corrugated pipes 3 come into contact with the limit ring 2, the connection is completed. At this time, the sealing ring 4 realizes the sealed connection between the adjacent corrugated pipes 3, and the elastic anti-detachment ring 5 can prevent the adjacent corrugated pipes 3 from loosening from the connector.
[0017] The above embodiments only illustrate the principle and efficacy of the present invention and some embodiments of its application, rather than limiting the present utility model. It should be noted that for those of ordinary skill in the art, without departing from the inventive concept of the present utility model, several modifications and improvements can still be made, and these all belong to the protection scope of the present utility model.
