Description
TECHNICAL FIELD
[0001] The present application relates to the field of pipe material, in particular to a pipe anti-disconnection structure and a pipe connection unit. BACKGROUND
[0002] The description in this section is only provided to relate to the background of the present disclosure and does not constitute prior art. Pipe material is a necessary material for construction engineering, and commonly used pipe materials include water supply pipes and drainage pipes. In order to facilitate transportation, the length of each pipe material cannot be too long, and on-site butt joint needs to be performed at the construction site. In the related art, during the process of geological subsidence, the pipe material will be subjected to axial pulling force, forcing the pipe material to axially deviate, and even to be disconnected from the connection, resulting in a decrease in sealing performance. In severe cases, groundwater will be inversely infiltrated into the pipe, causing the pipe network to be paralyzed. SUMMARY
[0003] Therefore, the present application provides a pipe anti-disconnection structure and a pipe connection unit, which can form a clamping structure and effectively prevent the pipe from being disconnected.
[0004] In order to achieve the above-mentioned purpose, the present application realizes the following technical solutions:
[0005] A pipe anti-disconnection structure, characterized in that: comprising a spigot section and a socket section, the socket section can receive the spigot section; one of the spigot section and the socket section is provided with a disconnection prevention groove, and the other is provided with a disconnection prevention protrusion, the disconnection prevention protrusion can extend into the disconnection prevention groove and be clamped therewith.
[0006] The pipe anti-disconnection structure described above can make the disconnection prevention protrusion extend into the disconnection prevention groove and be clamped therewith when the spigot section and the socket section are butt jointed, so that the pipe has a disconnection prevention capability and can effectively prevent the pipe from being disconnected.
[0007] In some embodiments, the disconnection prevention protrusion is connected with the spigot section or the socket section through an elastic universal joint. Through the elastic universal joint, the disconnection prevention protrusion can move in multiple directions relative to the spigot section or the socket section. When the pipe material is connected and buried in the soil, it will be subjected to forces in multiple directions, especially at the bending part of the pipe material or during geological subsidence. In order to offset these forces, the elastic universal joint is arranged on the disconnection prevention protrusion, so that the disconnection prevention protrusion becomes a movable part and plays a certain buffering role, reducing the occurrence of pipe material breakage or separation.
[0008] In some of the modes, the anti-disengagement convex part is pushed into the anti-disengagement groove in a radially expanded manner when the spigot section and the socket section are butted against each other, and the anti-disengagement convex part forms axial abutment in an axial direction. In the butting process, the anti-disengagement convex part is compressed and radially shrunk due to the elastic universal joint, so that the anti-disengagement convex part is smoothly pushed into the anti-disengagement groove, and then the anti-disengagement convex part is elastically expanded and clamped into the anti-disengagement groove. Such a pipeline installation structure is simple to install on site.
[0009] In some embodiments, the anti-disengagement convex part is an anti-disengagement tooth, and the elastic universal joint is an elastic ring connected to the root of the anti-disengagement tooth. The elastic ring includes a plurality of valley rings and peak rings which are arranged alternately and are nested with each other, forming an elastic wave structure.
[0010] Due to the elastic ring connected to the root of the anti-disengagement tooth, the anti-disengagement tooth is compressed and radially shrunk in the butting process, and the valley rings and the peak rings of the elastic ring are flattened. When the anti-disengagement tooth reaches the anti-disengagement groove, the elastic force of the material automatically resets the elastic ring, and the anti-disengagement tooth is radially extended. It should be noted that the elastic ring is a ring structure with multiple rings nested with each other, which can resist pulling force or pressure in multiple directions and play a buffering role. That is, the elastic ring and the spigot section or the socket section can move relative to each other in multiple angles or multiple directions.
[0011] In some embodiments, the number of anti-disengagement teeth is more than two and is arranged in a circumferential direction. Preferably, there are four anti-disengagement teeth.
[0012] In some embodiments, a hollow cavity is arranged in the spigot section, the elastic ring is integrally connected to the outer wall of the spigot section, the anti-disengagement tooth is also a hollow structure and communicates with the hollow cavity, and the anti-disengagement groove is arranged on the inner wall of the socket section. The hollow cavity can reduce the material usage of the spigot section.
[0013] In some embodiments, the elastic universal joint is an elastic ring integrally connected to the anti-disengagement convex part, and the elastic ring is arranged alternately in an axial direction by valley and peak. The elastic ring connected to the anti-disengagement convex part can also be flattened and elastically reset, so that the anti-disengagement convex part can move radially and conveniently butt the pipe. Moreover, the elastic ring allows the spigot section to bend in multiple directions at the elastic ring, similar to a straw structure. Furthermore, the elastic ring is located away from the port, and does not affect the sealing performance of the sealing ring when moving.
[0014] In some embodiments, the socket section is provided with a hollow cavity, the telescopic ring is integrally connected to the outer wall of the socket section and located on the side away from the port of the socket section, the anti-disengagement teeth are also hollow structures and communicate with the hollow cavity, and the anti-disengagement groove is arranged on the inner wall of the spigot section.
[0015] In some embodiments, the anti-disengagement protrusions are a plurality of spaced anti-disengagement teeth or an entire circle of anti-disengagement waves.
[0016] In some embodiments, one of the spigot section and the socket section is provided with a sealing installation groove, the sealing installation groove is provided with a sealing ring, the sealing ring is used for sealing connection of the spigot section and the socket section, and the sealing ring is located on the side close to the port of the socket section. The sealing installation groove is used for installing the sealing ring and can prevent the sealing ring from being displaced, and the sealing ring can play a role of pipeline sealing.
[0017] In some embodiments, the spigot section is provided with a sealing installation groove, the sealing installation groove is provided with a sealing ring, the socket section is provided with a sealing part for extrusion sealing with the sealing ring, and the telescopic ring and the sealing part are provided with an annular wave crest or an annular wave trough.
[0018] In some embodiments, the anti-disengagement groove is an entire circle of annular grooves or two or more circumferentially spaced interval grooves.
[0019] The application also provides a pipeline connection unit, characterized in that the pipeline connection unit comprises a body, and the body is provided with the socket section and / or the spigot section. The body can be a pipe material such as a corrugated pipe, or an inspection well. The two ends of the pipe material can be respectively provided with the socket section and the spigot section. Two types of pipe materials can also be provided. The two ends of the first type of pipe material are provided with the socket section, and the two ends of the second type of pipe material are provided with the spigot section, so that the two types of pipe materials can also be butted against each other. The body, the socket section and the spigot section are preferably integrally formed.
[0020] From the above technical solutions, the application has at least the following advantages and positive effects:
[0021] The pipeline anti-disengagement structure of the application can extend the anti-disengagement protrusions into the anti-disengagement groove for clamping when the socket section and the spigot section are butted against each other, so that the pipeline has the anti-disengagement capability and can effectively avoid disengagement of the pipeline.

DETAILED DESCRIPTION
[0031] In order to make the purpose, technical scheme and advantages of the present application more clear, the present application will be further described in detail below with reference to the drawings. The terms used in the embodiment part of the present application are only used to explain the specific embodiments of the present application, and are not intended to limit the present application.
[0032] Embodiment one
[0033] Referring to Figures 1 to 3 , the present embodiment provides a corrugated pipe made of plastic material, such as PP, PVC material. The corrugated pipe comprises a body 8, and a spigot section 1 and a socket section 2 are respectively arranged at both ends of the body 8, and the socket section 2 can receive the spigot section 1 of the adjacent pipe. The inner wall of the socket section 2 is provided with an anti-drop groove 4, and the spigot section 1 is provided with an anti-drop convex part, and when the two pipes are butt-jointed, the anti-drop convex part can be inserted into the anti-drop groove 4 of the other pipe and clamped therewith.
[0034] The anti-drop convex part is an elastic outward expansion structure that can change radially, and when the spigot section 1 and the socket section 2 are butt-jointed, the anti-drop convex part is pushed to the position of the anti-drop groove 4 in a radially contracted manner under pressure, and the anti-drop convex part enters the anti-drop groove 4 in a radially expanded manner to form an axial abutting limit. Wherein when the spigot section 1 and the socket section 2 are butt-jointed, the anti-drop convex part is first pressed and radially contracted, so that the anti-drop part can be smoothly pushed to the position of the anti-drop groove 4, and then the anti-drop convex part is elastically expanded and clamped into the anti-drop groove 4. Such a pipe installation structure is simple to install on site.
[0035] The anti-disengagement protrusion is an anti-disengagement tooth 3, and a telescopic ring 5 connected with the spigot section 1 is integrally connected at the root of the anti-disengagement tooth 3. The telescopic ring 5 comprises a plurality of valley rings 51 and crest rings 52 which are alternately arranged and sleeved with each other, thereby forming a corrugated structure.
[0036] Since the telescopic ring 5 is connected with the root of the anti-disengagement tooth 3, when the spigot section 1 and the socket section 2 are butted, the anti-disengagement tooth 3 is radially contracted by the extrusion of the inner wall of the socket section 2, and the valley rings 51 and the crest rings 52 of the telescopic ring 5 are flattened. When the anti-disengagement tooth 3 reaches the anti-disengagement groove 4, the elastic force of the material will drive the telescopic ring 5 to automatically reset, and the anti-disengagement tooth 3 is radially extended. The telescopic ring 5 is a ring structure of multiple rings which are sleeved with each other, and can resist the pulling force or pressure in multiple directions, thereby playing a buffering role to protect the pipe and reducing the disengagement of the pipeline. The force on the pipeline in the soil comes from multiple directions, especially in the bending and geological subsidence processes. The pipeline structure with the telescopic ring 5 is particularly suitable for the above two cases.
[0037] The number of the anti-disengagement tooth 3 is two or more and is arranged in the circumferential direction. Preferably, the number of the anti-disengagement tooth 3 is four.
[0038] The spigot section 1 is provided with a hollow cavity 11, the telescopic ring 5 is integrally connected to the outer wall of the spigot section 1, and the anti-disengagement tooth 3 is also a hollow structure which is communicated with the hollow cavity 11. The hollow cavity 11 can reduce the material usage of the spigot section 1.
[0039] One of the socket section 2 and the spigot section 1 is provided with a sealing installation groove 6, the sealing installation groove 6 is provided with a sealing ring 7, and the sealing ring 7 is used for sealing and connecting the socket section 2 and the spigot section 1. The sealing installation groove 6 is used for installing the sealing ring 7 and can prevent the displacement of the sealing ring 7. The sealing ring 7 can play a role of sealing the pipeline.
[0040] The anti-disengagement groove 4 is an annular groove or a plurality of spaced grooves which are arranged in the circumferential direction.
[0041] The working process and the use method of the corrugated pipe are briefly described as follows:
[0042] First, the sealing ring 7 is installed in the sealing installation groove 6. When the two corrugated pipes are butted, the spigot section 1 is aligned with the socket section 2 and is inserted into the socket section 2. The anti-disengagement tooth 3 is radially sunk and contracted by the extrusion of the inner wall of the socket section 2, and the telescopic ring 5 is flattened. When the anti-disengagement tooth 3 reaches the position of the anti-disengagement groove 4, the anti-disengagement tooth 3 is automatically reset and is clamped into the anti-disengagement groove 4 to form a clamping connection. The sealing ring 7 is extruded by the inner wall of the socket section 2 and the outer wall of the spigot section 1, thereby sealing the two pipes. When the pipeline is butted and buried in the soil, the anti-disengagement tooth 3 is a movable part which will relatively move the spigot section 1 when subjected to an external force, thereby offsetting the external force.
[0043] Embodiment Two
[0044] Referring to Figure 4 Another embodiment of the present application is shown, which is mainly different from the above-mentioned embodiments in that the anti-disengagement convex part is arranged on the socket section 2.
[0045] Specifically, it is a corrugated pipe, which comprises a body 8, a spigot section 1 and a socket section 2 are arranged at both ends of the body 8 respectively, and the socket section 2 can receive the spigot section 1 of an adjacent pipe. The socket section 2 is provided with an anti-disengagement convex part, and the outer wall of the spigot section 1 is provided with an anti-disengagement groove 4. When the two pipes are connected, the anti-disengagement convex part can extend into the anti-disengagement groove 4 of the other pipe and be clamped therewith.
[0046] The anti-disengagement convex part is an anti-disengagement tooth 3, and a flexible ring 5 connected with the socket section 2 is integrally connected at the root of the anti-disengagement tooth 3. The flexible ring 5 comprises a plurality of valley rings 51 and peak rings 52 which are sleeved on the outer periphery of the anti-disengagement tooth 3, and the valley rings 51 and the peak rings 52 are alternately arranged in concave-convex and ring-in-ring, thereby forming a corrugated structure.
[0047] The number of anti-disengagement teeth 3 is two or more and is arranged in a circumferential direction. Preferably, there are four anti-disengagement teeth 3.
[0048] One of the socket section 2 and the spigot section 1 is provided with a sealing installation groove 6, and a sealing ring 7 is arranged in the sealing installation groove 6. The sealing ring 7 is used for sealing the connection between the socket section 2 and the spigot section 1. The sealing installation groove 6 is used for installing the sealing ring 7 and can prevent the sealing ring 7 from moving. The sealing ring 7 can play the role of pipeline sealing.
[0049] The anti-disengagement groove 4 is an annular groove or two or more circumferentially spaced apart interval grooves.

[0051] Referring to Figures 5 to 6 Another embodiment of the present application is shown, which is mainly different from the first embodiment in that the flexible ring is replaced by a flexible ring, and the anti-disengagement part is an anti-disengagement wave.
[0052] Specifically, it is a corrugated pipe, which comprises a body 8, a spigot section 1 and a socket section 2 are arranged at both ends of the body 8 respectively, and the socket section 2 can receive the spigot section 1 of an adjacent pipe. The socket section 2 is provided with an anti-disengagement convex part, and the outer wall of the spigot section 1 is provided with an anti-disengagement groove 4. When the two pipes are connected, the anti-disengagement convex part can extend into the anti-disengagement groove 4 of the other pipe and be clamped therewith.
[0053] The anti-disengagement convex part is connected with the spigot section 1 or the socket section 2 through an elastic universal joint. Through the elastic universal joint, the anti-disengagement convex part can move in multiple directions relative to the spigot section 1 or the socket section 2.
[0054] The elastic universal joint is a telescopic ring 9 connected with the root of the anti-off convex part. The telescopic ring 9 is arranged alternately in the axial direction by valleys and peaks. The telescopic ring 9 connected with the anti-off convex part can also be flattened and elastically reset, so that the anti-off convex part can also be radially telescopic, facilitating the butt joint of the pipe. Moreover, the telescopic ring 9 can allow the spigot section 1 to be bent in multiple directions at the telescopic ring 9, similar to a straw structure. Moreover, the telescopic ring 9 is located away from the port side, and will not affect the sealing performance of the sealing ring 7 when moving.
[0055] The telescopic ring 9 is connected with the outer wall of the spigot section 1 and located away from the port side of the spigot section 1. The anti-off tooth is also a hollow structure and communicates with the hollow cavity 11. The anti-off groove 4 is arranged on the inner wall of the bell section 2.

The annular wave crest or the annular wave trough 13 can strengthen the circumferential compressive strength of this place, because this place is originally close to the sealing ring, and the spigot is long and hollow. The extrusion of the sealing ring can cause the flat part to be inwardly concave.
