Description

Technical Field

[0001] This application relates to the field of pipe materials, and particularly to an anti - detachment pipe. Background Art

[0002] Pipe materials are essential materials for construction projects. Commonly used ones include water supply pipes, drainage pipes, etc. For the convenience of transportation, the length of each section of pipe is not made too long, and on - site docking is required at the construction site. In related technologies, during the geological settlement process, an axial pulling force is generated on the pipe, forcing the pipe to axially shift and even disconnect from the connection, resulting in a decline in sealing performance. Seriously, groundwater will infiltrate back into the pipeline, causing the pipe network to collapse. Summary of the Invention

[0003] In view of this, this application provides an anti - detachment pipe that can achieve rapid docking of pipes and has an anti - detachment function.

[0004] To achieve the above - mentioned purpose, this application is realized through the following technical solutions:

[0005] An anti - detachment pipe, characterized in that: it includes a pipe body, and a receiving pipe and an inserting pipe are integrally connected to both ends of the pipe body respectively. The receiving pipe can receive the inserting pipe of another pipe; an anti - detachment wave protruding radially outward from the pipe is provided on the inserting pipe. The outer shape of the anti - detachment wave is circular. An anti - detachment groove for accommodating the anti - detachment wave is provided inside the receiving pipe. A blocking ring protruding radially inward from the pipe is integrally provided at the front end of the anti - detachment groove in the receiving pipe. When the anti - detachment wave is in the anti - detachment groove, the blocking ring restricts the axial outward movement of the anti - detachment wave in a clamping form; the inner pipe orifice of the blocking ring is square, and chamfers are made at the four corners of the square. The anti - detachment wave is elastic, and the maximum outer circumference of the anti - detachment wave is smaller than the circumference of the smallest inner pipe orifice of the blocking ring. Thus, when the receiving pipe and the inserting pipe are butted towards each other, the blocking ring is squeezed by the anti - detachment wave and undergoes an expansion deformation to enable the anti - detachment wave to enter the position of the anti - detachment groove and form a clamp.

[0006] For the above - mentioned anti - detachment pipe of this application, an anti - detachment groove and a blocking ring are provided on the receiving pipe, and an anti - detachment wave is provided on the inserting pipe. When the inserting pipe is butted with the receiving pipe of another pipe, the anti - detachment wave can push open the blocking ring to enable the anti - detachment wave to enter the anti - detachment groove to form a clamp. The pipe docking is convenient and has an axial anti - detachment function. And this pipe is of an integral structure, and the anti - detachment function can be realized without adding extra accessories, which is convenient for processing and has good economic benefits.

[0007] In some embodiments, the outer shape of the receiving pipe at the anti - detachment groove is also a square structure. The outer shape at the anti - detachment groove is a square structure. Compared with a circular structure, the pipe is not easy to roll when placed, which is convenient for transportation.

[0008] In some embodiments, the receiving pipe further includes a sealing section. The inserting pipe is a corrugated pipe with alternating circular crests and troughs. A sealing ring is installed in one trough of the inserting pipe, and the sealing ring is sealingly connected to the sealing section of the receiving pipe. The sealing ring is provided to ensure the sealing performance between the pipes.

[0009] In some embodiments, the pipe body is also a corrugated pipe with alternating circular crests and troughs. The crest of the inserting pipe is smaller than the crest of the pipe body. The anti - detachment wave has the same size as the crest of the pipe body or the size of the anti - detachment wave is between the crest of the pipe body and the crest of the inserting pipe. The anti - detachment wave can be directly selected from one of the crests on the corrugated pipe or a separate crest is provided between the crest of the pipe body and the crest of the inserting pipe.

[0010] In some embodiments, the receiving pipe further includes a transition section and an anti - detachment section. The transition section is integrally connected to the pipe body, the sealing section is integrally connected to the transition section, the anti - detachment section is integrally connected to the sealing section. The inner wall of the sealing section is a conical structure with a larger inner diameter near the port side. The anti - detachment groove and the blocking ring are both provided on the sealing section. The sealing ring is squeezed and sealed with the sealing section, and the anti - detachment wave is always pressed against the blocking ring. Since the sealing section is a conical structure, the sealing ring will generate an axial resilience force when pressed inward. By pressing the anti - detachment wave against the blocking ring all the time, the axial resilience of the sealing ring is restricted. Compared with the sealing connection of the straight section, the sealing effect is better in this way.

[0011] In some embodiments, a conical guiding wall is further provided on the inner wall of the blocking ring. The conical guiding wall is a conical structure with a larger inner diameter near the port side. The conical guiding wall is provided to facilitate the insertion of the inserting pipe.

[0012] From the above technical solutions, it can be seen that the present application has at least the following advantages and positive effects:

[0013] For an anti - detachment pipe of the present application, an anti - detachment groove and a blocking ring are provided on the receiving pipe, and an anti - detachment wave is provided on the inserting pipe. When the inserting pipe is butted with the receiving pipe of another pipe, the anti - detachment wave can push open the blocking ring so that the anti - detachment wave enters the anti - detachment groove to form a clamping connection. The butt - joint of the pipe is convenient and has an axial anti - detachment function. And the pipe is an integral structure, and the anti - detachment function can be realized without adding extra accessories, which is convenient for processing and has good economic benefits.

[0021] In order to make the purpose, technical solution and advantages of the present application clearer, the present application will be further described in detail below in conjunction with the accompanying drawings.

[0022] See also Figures 1 to 4 The embodiment of the present application provides an anti-slipping pipe, including a pipe body 1, at both ends of which are integrally connected a receiving pipe 2 and a plug-in pipe 3, respectively, the receiving pipe 2 can receive the plug-in pipe 3 of another pipe; the plug-in pipe 3 is provided with an anti-slipping wave 31 protruding radially outwardly of the pipe, the anti-slipping wave 31 is annular in shape, the receiving pipe 2 is provided with an anti-slipping groove 231 for accommodating the anti-slipping wave 31, the receiving pipe 2 is integrally provided with a blocking ring 232 protruding radially inwardly of the pipe at the front end of the anti-slipping groove 231, When the anti-slip wave 31 is in the anti-slip groove 231, the blocking ring 232 limits the axial outward movement of the anti-slip wave 31 in the form of a clamping connection; the inner pipe opening of the blocking ring 232 is a square, and the four corners of the square are chamfered. The anti-slip wave 31 is elastic, and the maximum outer circumference of the anti-slip wave 31 is smaller than the circumference of the minimum inner pipe opening of the blocking ring 232. Therefore, when the receiving pipe 2 and the plug-in pipe 3 are docked, the blocking ring 232 is squeezed by the anti-slip wave 31, and the expansion deformation can make the anti-slip wave 31 enter the anti-slip groove 231 and form a clamping connection. The tube body can be as follows Figure 1 Circular bellows shown.

[0023] See also Figure 3 When the blocking ring 232 is squeezed by the anti-falling wave 31, the blocking ring 232 will Figure 3In the shown manner, the chamfered part deforms radially inward into the pipe, and the straight part deforms radially outward from the pipe, so that the blocking ring 232 can enter the position of the anti-disengagement groove 231. Subsequently, the blocking ring 232 resets to form a clamping structure. The blocking ring is a whole-ring structure with excellent anti-disengagement performance.

[0024] For this anti-disengagement pipe, an anti-disengagement groove 231 and a blocking ring 232 are provided on the receiving pipe 2, and an anti-disengagement wave 31 is provided on the inserted pipe 3. When the inserted pipe 3 is docked with the receiving pipe 2 of another pipe, the anti-disengagement wave 31 can push open the blocking ring 232 to enable the anti-disengagement wave 31 to enter the anti-disengagement groove 231 to form a clamp. The docking of this pipe is convenient and has an axial anti-disengagement function. Moreover, this pipe is an integral structure, and the anti-disengagement function can be realized without adding additional accessories, which is convenient for processing and has good economic benefits.

[0025] The outer shape of the receiving pipe 2 at the anti-disengagement groove 231 is also a square structure. The outer shape at the anti-disengagement groove 231 is a square structure. Compared with a circular structure, the pipe is not easy to roll when placed, which is convenient for transportation.

[0026] The receiving pipe 2 further includes a sealing section 22. The inserted pipe 3 is a corrugated pipe with alternating circular wave crests and wave troughs. A sealing ring 4 is installed in a wave trough of the inserted pipe 3, and the sealing ring 4 is hermetically connected to the sealing section 22 of the receiving pipe 2. The sealing ring 4 is provided to ensure the sealing between pipes.

The transition section 21 is integrally connected to the pipe body 1, the sealing section 22 is integrally connected to the transition section 21, the anti-disengagement section 23 is integrally connected to the sealing section 22. The inner wall of the sealing section 22 is a conical structure with a larger inner diameter near the port side. The anti-disengagement groove 231 and the blocking ring 232 are both provided on the sealing section 22. The sealing ring 4 is hermetically sealed by extrusion with the sealing section 22, and the anti-disengagement wave 31 is always tightly pressed against the blocking ring 232. Among them, the sealing section 22 is a conical structure. When the sealing ring 4 is pressed inward, an axial resilience force will be generated. By always tightly pressing the anti-disengagement wave 31 through the blocking ring 232, the axial resilience of the sealing ring 4 is restricted. Compared with the sealing connection of a straight section, the sealing effect is better in this way.

[0028] A conical guiding wall 2321 is further provided on the inner wall of the blocking ring 232. The conical guiding wall 2321 is a conical structure with a larger inner diameter near the port side. The conical guiding wall 2321 is provided for facilitating the insertion of the inserted pipe 3.

[0029] Refer to Figures 1 to 4 , the pipe body 1 is also a corrugated pipe with alternating circular wave crests and wave troughs. The wave crest of the inserted pipe 3 is smaller than that of the pipe body 1, and the size of the anti-disengagement wave 31 is between the wave crest of the pipe body 1 and the wave crest of the inserted pipe 3.

[0030] In another embodiment, referring to Figures 5 to 6 , the anti - detachment wave 31 has the same size as the wave crest of the tube body 1, and the anti - detachment wave 31 can be directly selected from a wave crest on the corrugated tube. In this way, the change in the pipe material is smaller.
