Description

Technical Field

[0001] This utility model relates to the field of corrugated pipe connection technology, and in particular to a quick-connect connector for corrugated pipes. Background Technology

[0002] Bellows expansion joints, also known as expansion joints, are commonly called compensators or expansion joints. They are used to compensate for axial, lateral, and angular displacements of pipelines, conduits, containers, etc., and are typically used to connect two pipes to improve the flexibility of the connection.

[0003] The connection between corrugated pipes and pipelines is generally achieved by fitting the corrugated pipe onto the pipeline and then tightening the clamps to secure the corrugated pipe, or by using flanges and bolts for installation. This method is relatively cumbersome and not conducive to the rapid installation of corrugated pipes. Utility Model Content

[0004] In order to overcome the above-mentioned defects in the prior art, this utility model provides a bellows quick connection connector.

[0005] The technical solution adopted by this utility model to solve its technical problem is: a corrugated pipe quick connection connector, including a corrugated pipe and a pipe. The right end of the corrugated pipe is provided with a first slope portion, and the outer side of the left end of the pipe is provided with a second slope portion. The second slope portion and the first slope portion are fitted and installed together. The outer side of the pipe is provided with a mating portion. The right end of the first slope portion is provided with an installation portion. The installation portion and the mating portion are fitted together through a sealing ring. The upper ends of the mating portion and the installation portion are pressed together by an installation block. Several sets of installation blocks are movably installed on the outer side of the corrugated pipe.

[0006] Furthermore, a welding section is provided on the left side of the mounting section.

[0007] Furthermore, the lower end of the mounting block is provided with a trapezoidal groove, which is used in conjunction with the welding part and the mating part for installation.

[0008] Furthermore, a rotating ring is detachably mounted on the upper end of the mounting block via a tapered thread, and the mounting block can be pressed down by rotating the rotating ring.

[0009] Furthermore, several sets of fixing brackets are fixedly installed on the outer side of the corrugated pipe, the fixing brackets are movably mounted with a mounting shaft, a connecting rod is fixedly installed on the mounting shaft, and a mounting block is fixedly installed on the right side of the connecting rod.

[0010] The beneficial effects of this utility model are: the corrugated pipe and the pipeline are connected by the cooperation of the first slope and the second slope, and then the mounting block is flipped so that the trapezoidal groove of the mounting block, the mounting part and the welding part cooperate. Then the rotating ring is installed, and the mounting block is pressed down by rotating the rotating ring, so that the installation between the corrugated pipe and the pipeline is more secure. The overall installation is relatively simple and can achieve rapid installation. Attached Figure Description

[0016] To more clearly illustrate the technical solution of this utility model, the following description is made in conjunction with the accompanying drawings. Obviously, the drawings described below are only one embodiment of this utility model. For those skilled in the art, other embodiments can be obtained based on these drawings and embodiments without creative effort, and all of them fall within the protection scope of this utility model.

[0017] like Figures 1 to 3 As shown, this utility model includes a corrugated pipe 1 and a pipe 4. The inner side of the corrugated pipe 1 is provided with an inner liner 2. The right end of the corrugated pipe 1 is provided with a first slope portion 3. The outer side of the left end of the pipe 4 is provided with a second slope portion 6. The second slope portion 6 and the first slope portion 3 are installed in contact.

[0018] like Figures 1 to 3As shown, a mating part 5 is provided on the outer side of the pipe 4, and an installation part 7 is provided at the right end of the first slope part 3. The installation part 7 and the mating part 5 are installed in contact through a sealing ring 9. The upper ends of the mating part 5 and the installation part 7 are pressed together by an installation block 10. Several sets of installation blocks 10 are movably installed on the outer side of the corrugated pipe 1. Several sets of fixing brackets 14 are fixedly installed on the outer side of the corrugated pipe 1. The fixing brackets 14 are movably installed with an installation shaft 15. A connecting rod 13 is fixedly installed on the installation shaft 15. An installation block 10 is fixedly installed on the right side of the connecting rod 13.
