Description

Technical Field

[0001] This utility model relates to the field of double-wave tube technology, specifically a double-wave tube with an anti-misalignment mechanism. Background Technology

[0002] Double-corrugated pipes are structural wall pipes made of high-density polyethylene and other materials. Their distinguishing feature is the special design of their inner and outer walls. The outer wall has a ring-shaped corrugation, enhancing ring stiffness and resistance to external pressure, while the inner wall is smooth, reducing fluid resistance and preventing dirt buildup. These pipes are widely used in municipal drainage, sewage, water supply, ventilation, and agricultural irrigation, and are particularly suitable for scenarios with high requirements for soil load or geological settlement. Compared to traditional cement pipes or solid-wall pipes, double-corrugated pipes have significant advantages, including lighter weight, easier construction, stronger corrosion resistance, a service life of up to 50 years, and zero leakage through flexible connection methods.

[0003] However, in actual use, the outer diameter of one side of the above-mentioned double-wave pipe is equal to the inner diameter of the other side. The outer and inner diameters are exactly the same, which lacks sufficient clearance to guide the correct docking of the pipe. Since slight deviations or non-parallelism are prone to occur during docking, the pipe is difficult to align accurately, resulting in misalignment. In view of this, we propose a double-wave pipe with an anti-misalignment mechanism. Utility Model Content

[0004] The purpose of this invention is to provide a double-wave peak pipe with an anti-misalignment mechanism to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a double-wave peak pipe with an anti-misalignment mechanism, comprising a pipe body, wherein docking components are provided on both sides of the pipe body, and the docking components include:

[0006] The left connector is fixedly connected to the left end face of the pipe body. The outer wall of the left connector has a threaded groove. A cover is fixedly connected to the outer wall of the left connector. A barb is fixedly connected to the inner wall of the cover.

[0007] The right connector is fixedly connected to the right end face of the pipe body. The end of the right connector away from the pipe body is fixedly connected to a flared mouth. The outer wall of the right connector is provided with a hook groove, and the inner wall of the right connector is fixedly connected with an external thread.

[0008] Preferably, the flared end has a large diameter end and a small diameter end, the outer diameter of the small diameter end is equal to the outer diameter of the right connector, and the large diameter end is located at the end of the flared end away from the right connector.

[0009] Preferably, the outer diameter of the larger diameter end is smaller than the outer diameter of the cover, and the barb is movably connected to the hook groove.

[0010] Preferably, the outer diameter of the left connector is equal to the inner diameter of the right connector, the external thread is threaded to the thread groove, and the pipe body is rotated to make the external thread threaded to the thread groove, thereby connecting the two sets of pipe bodies together.

[0011] Preferably, the number of hook grooves is set in several groups, and the several groups of hook grooves are equally spaced on the outer wall with the right connector.

[0012] Preferably, the barb is arranged in a ring shape and is elastic. The end of the barb away from the inner wall of the cover faces the side closer to the pipe body. The barb can be deformed by being squeezed by the outer wall of the right connector. At the same time, after the right connector is engaged with the hook groove, it can prevent the two sets of pipe bodies from being pulled out.

[0013] Preferably, the left connector is fixedly connected to a flared end away from the pipe body. The flared end has a large diameter end and a small diameter end. The outer diameter of the large diameter end is equal to the outer diameter of the left connector. The small diameter end is located on the side of the flared end away from the left connector. The inner diameter of the large diameter end is equal to the inner diameter of the small diameter end. The inner diameter of the large diameter end is equal to the inner diameter of the pipe body.

[0014] Compared with the prior art, this utility model provides a double-wave peak pipe with an anti-misalignment mechanism, which has the following beneficial effects:

[0015] 1. This double-wave-shaped pipe with an anti-misalignment mechanism, through its designed docking assembly, uses the conical structure of the flared end to guide the left and right connectors during the docking process, allowing the left connector to be smoothly inserted into the right connector. In the initial insertion stage, the flared end structure helps align the pipes, making it easier for the external thread and thread groove to engage, reducing thread engagement difficulties caused by misalignment, and improving assembly quality and stability. The flared end structure expands the insertion range, allowing operators to connect smoothly without precise alignment, improving assembly efficiency. After the right connector engages with the hook groove, even under axial tension, the pipe bodies will not easily separate, improving the overall connection reliability, preventing the two sets of pipe bodies from being pulled out, and preventing thread loosening. Multiple hook grooves allow for insertion depths of varying depths, enabling the connection structure to be adjusted according to actual needs, making it suitable for different working conditions and enhancing applicability.

[0016] 2. This double-wave-shaped pipe with an anti-misalignment mechanism, through the setting of the second flared end, allows the outer wall of the second flared end to be movably connected with the inner wall of the first flared end during docking. The guiding effect of the second and first flared ends can gradually center the pipe, making the insertion force evenly distributed, reducing assembly resistance, improving installation efficiency, and avoiding damage or deformation of the pipe body due to excessive insertion force. It also reduces misalignment problems caused by human operation errors and improves docking accuracy. Attached Figure Description

[0022] like Figures 1-4 As shown, this utility model provides a technical solution: a double-wave peak pipe with an anti-misalignment mechanism, including a pipe body 1, and connecting components 2 are provided on both sides of the pipe body 1. The connecting components 2 include a left connector 201, a threaded groove 202, a cover 203, a barb 204, a right connector 205, a flared mouth 206, a hook groove 207, and an external thread 208.

[0023] In one embodiment of this utility model, the left connector 201 is fixedly connected to the left end face of the pipe body 1. The outer wall of the left connector 201 is provided with a threaded groove 202. A cover 203 is fixedly connected to the outer wall of the left connector 201. A barb 204 is fixedly connected to the inner wall of the cover 203. The right connector 205 is fixedly connected to the right end face of the pipe body 1. A flared mouth 206 is fixedly connected to the end of the right connector 205 away from the pipe body 1. A hook groove 207 is provided on the outer wall of the right connector 205. Several sets of hook grooves 207 are provided. Several sets of hook grooves 207 are equally spaced on the outer wall of the right connector 205. An external thread 208 is fixedly connected to the inner wall of the right connector 205. The outer diameter of the left connector 201 is equal to the inner diameter of the right connector 205. The external thread 208 is threadedly connected to the threaded groove 202. By rotating the pipe body 1, the external thread 208 is threadedly connected to the threaded groove 202, thereby connecting the two sets of pipe bodies 1 together.

[0024] The flared end 206 is provided with a large diameter end and a small diameter end. The outer diameter of the small diameter end is equal to the outer diameter of the right connector 205. The large diameter end is located at the end of the flared end 206 away from the right connector 205. The outer diameter of the large diameter end is smaller than the outer diameter of the cover 203. The barb 204 is movably connected to the hook groove 207. The barb 204 is arranged in a ring shape and is elastic. The end of the barb 204 away from the inner wall of the cover 203 faces the side close to the pipe body 1. The barb 204 can be deformed by being squeezed by the outer wall of the right connector 205. At the same time, after the right connector 205 is engaged with the hook groove 207, it can prevent the two sets of pipe bodies 1 from being pulled out.

[0025] The outer diameter of the left connector 201 is equal to the inner diameter of the right connector 205. The external thread 208 is threadedly connected to the threaded groove 202. By rotating the pipe body 1, the external thread 208 is threadedly connected to the threaded groove 202, thereby connecting the two sets of pipe bodies 1 together. The conical structure of the flared end 206 plays a guiding role in the docking process of the left connector 201 and the right connector 205, allowing the left connector 201 to be smoothly inserted into the right connector 205. In the initial stage of insertion, the flared end structure helps to align the pipes first, making it easier for the external thread 208 and the threaded groove 202 to engage, reducing the difficulty of thread engagement caused by misalignment, and improving assembly quality and stability. If pipes of the same size are directly docked, even a slight deviation may lead to insertion difficulties. However, the flared end 206 structure can expand the insertion range, allowing operators to connect smoothly without precise alignment, thus improving assembly efficiency.

[0026] During the insertion of the left connector 201 into the right connector 205, the barb 204 is deformed by the outer wall of the right connector 205. After the right connector 205 is engaged with the hook groove 207, even under axial tension, the pipe body 1 will not easily separate, improving the reliability of the overall connection and preventing the two sets of pipe bodies 1 from being pulled out. During vibration, impact, or long-term use, relying solely on the threaded connection may gradually loosen due to external forces. The barb 204 structure provides additional mechanical locking force to prevent the threads from loosening and improve the long-term stability of the pipeline system. The number of hook grooves 207 is set to several sets, and multiple hook grooves 207 can allow insertion at different depths, so that the connection structure can be adjusted according to actual needs, making it suitable for different working conditions and enhancing applicability.

[0027] In addition, a flared end 201 is fixedly connected to the end of the left connector 201 away from the pipe body 1. Flared end 201 has a large diameter end and a small diameter end. The outer diameter of the large diameter end is equal to the outer diameter of the left connector 201. The small diameter end is located on the side of flared end 201 away from the left connector 201. The inner diameter of the large diameter end is equal to the inner diameter of the small diameter end. The inner diameter of the large diameter end is equal to the inner diameter of the pipe body 1. When the small diameter end of flared end 201 gradually narrows, the outer wall of flared end 202 is movably connected to the inner wall of flared end 206. The guiding effect of flared end 202 and flared end 206 can make the pipe gradually align, so that the insertion force is evenly distributed, reducing assembly resistance, improving installation efficiency, and avoiding damage or deformation of pipe body 1 due to excessive insertion force. It also reduces misalignment problems caused by human operation errors and improves the docking accuracy.

[0028] In this invention, during use, the pipe body 1 is rotated to connect the external thread 208 with the threaded groove 202, thereby connecting the two sets of pipe bodies 1 together. The conical structure of the flared end 206 guides the left connector 201 and right connector 205 during the mating process, allowing the left connector 201 to be smoothly inserted into the right connector 205. In the initial insertion stage, the flared end structure helps to align the pipes first, making it easier for the external thread 208 and threaded groove 202 to engage, reducing thread engagement difficulties caused by misalignment, and improving assembly quality and stability. If pipes of the same size are directly mated, even a slight deviation may lead to insertion difficulties, while the flared end 206... The structure expands the insertion range, allowing operators to connect smoothly without precise alignment, thus improving assembly efficiency. During the insertion of the left connector 201 into the right connector 205, the barb 204 is deformed by the outer wall of the right connector 205. After the right connector 205 is engaged with the hook groove 207, even under axial tension, the pipe body 1 will not easily separate, improving the reliability of the overall connection and preventing the two sets of pipe bodies 1 from being pulled out. During vibration, impact, or long-term use, relying solely on threaded connections may gradually loosen due to external forces. The barb 204 structure provides additional mechanical locking force to prevent the threads from loosening, thus improving the long-term stability of the pipeline system.

[0029] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
