Description

Technical Field

[0001] This utility model relates to the field of corrugated pipe technology, and in particular to a double-layer corrugated pipe structure. Background Technology

[0002] Corrugated pipes are pipes with a corrugated structure, typically used for transporting liquids or gases. They offer good flexibility and are widely used in industries such as construction, chemical engineering, and municipal engineering. One type is the double-layer corrugated pipe made of plastic, which consists of two corrugated pipes connected together.

[0003] The above-mentioned and existing technologies have the following defects: When assembling double-layer corrugated pipes, a socket process is used for docking. However, during application, the ports of the double-layer corrugated pipes are prone to deformation when subjected to collisions, which can easily lead to cracks at the joints of the double-layer corrugated pipes and leakage of the transported material inside the double-layer corrugated pipes.

[0004] Therefore, a double-layer corrugated pipe structure is proposed. Utility Model Content

[0005] The purpose of this invention is to solve the problem that the ends of double-layer corrugated pipes are prone to deformation when subjected to impact, which can easily lead to cracking at the joints of the double-layer corrugated pipes. Therefore, a double-layer corrugated pipe structure is proposed.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a double-layer corrugated pipe structure, comprising an internally threaded pipe, an externally threaded pipe fixedly connected to the arc surface of the internally threaded pipe, a rigid ring fixedly connected to the arc surface of the internally threaded pipe, a clamping plate fixedly connected to the arc surface of the rigid ring, a connecting block slidably connected to the inner wall of the clamping plate, a rubber block fixedly connected to the surface of the connecting block, and a protective ring fixedly connected to the surface of the rubber block.

[0007] The effect achieved by the above components is that the protective ring can withstand the impact from the outside and transfer the impact force to the rubber block. The rubber block will deform to absorb the impact, thereby reducing the impact on the internally threaded pipe and preventing the joint of the double-layer corrugated pipe from cracking, which would lead to leakage of the conveyed material inside the double-layer corrugated pipe.

[0008] Preferably, two limiting rods slide through the card plate, and the connecting block is located between the two limiting rods.

[0009] The effect achieved by the above components is that the limiting rod restricts the position of the connecting block, thereby restricting the position of the protective ring.

[0010] Preferably, a strip plate is fixedly connected to one end of each of the two limiting rods.

[0011] The effect achieved by the above components is that the strip plate can simultaneously drive the two limit rods to move.

[0012] Preferably, a guide block is fixedly connected to the end of the limiting rod away from the strip plate.

[0013] The effect achieved by the above components is that the guide block can move the limiting rod, making it easier for the limiting rod to pass through the card plate.

[0014] Preferably, a magnetic strip is fixedly connected to the side of the strip plate near the card plate, and the card plate is an iron plate.

[0015] The effect achieved by the above components is that when the magnetic strip comes into contact with the card plate, the magnetic strip will be attracted to the surface of the card plate, and the magnetic strip will restrict the position of the strip plate.

[0016] Preferably, the inner wall of the rigid tube is fixedly connected with a plurality of protrusions, and the protrusions are fixedly connected to the internally threaded tube.

[0017] The effect achieved by the above components is that the bumps can improve the connection stability between the hard ring and the internally threaded pipe.

[0018] Preferably, the cross-section of the protective ring is wavy.

[0019] The effect achieved by the above components is that the protective ring with a wave-shaped cross-section can deform and absorb the impact force after being impacted.

[0020] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0021] In this invention, the protective ring can withstand impacts from the outside and transmit the impact force to the rubber block. The rubber block will deform to absorb the impact, thereby reducing the impact on the internally threaded pipe and preventing cracking at the connection of the double-layer corrugated pipe, which could lead to leakage of the conveyed material inside the double-layer corrugated pipe.

[0028] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0029] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0030] like Figures 1-5 As shown, this utility model provides a double-layer corrugated pipe structure, including an internally threaded pipe 1, an externally threaded pipe 2 fixedly connected to the arc surface of the internally threaded pipe 1, a rigid ring 3 fixedly connected to the arc surface of the internally threaded pipe 1, a clamping plate 4 fixedly connected to the arc surface of the rigid ring 3, a connecting block 5 slidably connected to the inner wall of the clamping plate 4, a rubber block 6 fixedly connected to the surface of the connecting block 5, and a protective ring 7 fixedly connected to the surface of the rubber block 6. The protective ring 7 can withstand impacts from the outside and transmit the impact force to the rubber block 6. The rubber block 6 will deform to absorb the impact, thereby reducing the impact on the internally threaded pipe 1 and preventing cracking at the connection of the double-layer corrugated pipe, which would lead to leakage of the conveyed material inside the double-layer corrugated pipe. Two limiting rods 8 slide through the clamping plate 4, and the connecting block 5 is located between the two limiting rods 8. The limiting rods 8 limit the position of the connecting block 5, thereby limiting the position of the protective ring 7.

[0031] like Figures 3-5 As shown, one end of each of the two limiting rods 8 is fixedly connected to a strip plate 9. The strip plate 9 can simultaneously drive the two limiting rods 8 to move. The end of the limiting rod 8 away from the strip plate 9 is fixedly connected to a guide block 11. The guide block 11 can move the limiting rod 8, making it convenient for the limiting rod 8 to pass through the clamping plate 4. A magnetic strip 10 is fixedly connected to the side of the strip plate 9 near the clamping plate 4. The clamping plate 4 is an iron plate. When the magnetic strip 10 contacts the clamping plate 4, the magnetic strip 10 will be attracted to the surface of the clamping plate 4. The magnetic strip 10 achieves the function of limiting the position of the strip plate 9. Several protrusions 12 are fixedly connected to the inner wall of the rigid tube. The protrusions 12 are fixedly connected to the internally threaded tube 1. The protrusions 12 can improve the connection stability between the rigid ring 3 and the internally threaded tube 1. The protective ring 7 has a wavy cross section. The protective ring 7 with a wavy cross section can deform after being impacted to absorb the impact force.

[0032] The overall working principle is as follows: when the port of the internally threaded pipe 1 needs to be protected, the connecting block 5 is slid into the inner wall of the clamping plate 4. At this time, the clamping plate 4 restricts the position of the connecting block 5, thereby restricting the position of the protective ring 7. The protective ring 7 can withstand the impact from the outside and transmit the impact force to the rubber block 6. The rubber block 6 will deform to absorb the impact, thereby reducing the impact on the internally threaded pipe 1. In addition, the protective ring 7 with a wave-shaped cross section can also deform to absorb the impact force after being impacted. Then, the strip plate 9 is moved, and the strip plate 9 will simultaneously drive the two limiting rods 8 to pass through the clamping plate 4. At this time, the limiting rods 8 restrict the position of the connecting block 5, thereby restricting the position of the protective ring 7. During this process, the guide block 11 can move the limiting rods 8 to facilitate the passing of the limiting rods 8 through the clamping plate 4. When the magnetic strip 10 contacts the clamping plate 4, the magnetic strip 10 will be attracted to the surface of the clamping plate 4. The magnetic strip 10 restricts the position of the strip plate 9. The protrusion 12 can improve the connection stability between the hard ring 3 and the internally threaded pipe 1.

[0033] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
