Description

Technical Field

[0001] The present application relates to the field of pipes, and in particular to a pipe anti-drop structure and a pipe connection unit. Background Art

[0002] The descriptions in this section only provide background information related to the present disclosure and do not constitute prior art. Pipes are essential materials for construction projects, and commonly used ones include water supply pipes, drainage pipes, etc. For the convenience of transportation, the length of each section of pipe will not be too long, and it is necessary to connect them on site. In the related art, during the geological settlement process, the pipe will generate axial pulling force on the pipe, forcing the pipe to deviate axially or even detach from the connection, resulting in a decrease in sealing performance. In severe cases, groundwater will infiltrate into the pipeline, causing the pipeline network to be paralyzed. Summary of the invention

[0003] In view of this, the present application provides a pipeline anti-detachment structure and a pipeline connecting unit, which can form a clamping structure to effectively prevent the pipeline from detaching.

[0004] In order to achieve the above objectives, this application is implemented through the following technical solutions:

[0005] A pipeline anti-slip structure, characterized in that it includes a plug section and a socket section, the socket section can receive the plug section; one of the plug section and the socket section is provided with an anti-slip groove, and the other is provided with an anti-slip protrusion, and the anti-slip protrusion can extend into the anti-slip groove and clamp therewith.

[0006] The above-mentioned pipeline anti-drop structure of the present application has an anti-drop protrusion that can extend into the anti-drop groove and snap into engagement with the anti-drop groove when the spigot section and the socket section are butt-jointed, so that the pipeline has an anti-drop capability and can effectively prevent the pipeline from falling off.

[0007] In some embodiments, an elastic universal joint is connected between the anti-slip protrusion and the socket section or the socket section, and the anti-slip protrusion can move in multiple directions relative to the socket section or the socket section through the elastic universal joint. When the pipe is buried in the soil after docking, it will be subject to forces in multiple directions, especially at the bend of the pipe or when geological settlement occurs, the forces are particularly obvious. In order to offset these forces, an elastic universal joint is provided on the anti-slip protrusion, so that the anti-slip protrusion can become a movable part, play a certain buffering role, and reduce the occurrence of breaking the pipe or separation of the pipe.

[0008] In some of the above methods, when the socket section and the bell section are butted against each other, the anti-slip protrusion is pressed and pushed to the position of the anti-slip groove in a radially contracted manner, and the anti-slip protrusion enters the anti-slip groove in a radially expanded manner to form an axial contact limit. When the socket section and the bell section are butted against each other, since the anti-slip protrusion has an elastic universal joint, the anti-slip protrusion is pressed and can shrink radially, so that the anti-slip part can be smoothly pushed to the position of the anti-slip groove, and then the anti-slip protrusion is elastically expanded and stuck in the anti-slip groove. Such a pipeline installation structure is simple to install on site.

[0009] In some embodiments, the anti-slip protrusion is an anti-slip tooth, and the elastic universal joint is a telescopic ring integrally connected to the root of the anti-slip tooth. The telescopic ring includes a plurality of trough rings and peak rings sleeved on the outer periphery of the anti-slip tooth. The trough rings and peak rings are alternately arranged with concave and convex shapes and are sleeved on each other to form a telescopic corrugated structure.

[0010] Since the root of the anti-slip tooth is connected with a telescopic ring, when the spigot section and the socket section are connected, the anti-slip tooth is compressed and radially contracts, and the trough ring and the peak ring of the telescopic ring will be flattened. When the anti-slip tooth reaches the anti-slip groove, the elastic force of the material will drive the telescopic ring to automatically reset, and the anti-slip tooth will extend radially. Another point that needs to be explained is that the telescopic ring is a ring structure with multiple circles interconnected, which can resist tension or pressure in multiple directions and play a buffering role. That is, the telescopic ring and the spigot section or the socket section can perform relative movement at multiple angles or in multiple directions.

[0011] In some embodiments, the number of the anti-slip teeth is two or more and they are arranged at intervals along the circumferential direction. Preferably, there are four anti-slip teeth.

[0012] In some embodiments, a hollow cavity is provided in the socket section, the expansion ring is integrally connected to the outer wall of the socket section, the anti-slip teeth are also hollow structures communicating with the hollow cavity, and the anti-slip grooves are provided on the inner wall of the socket section. The hollow cavity can reduce the material used in the socket section.

[0013] In some embodiments, the elastic universal joint is a telescopic ring integrally connected to the anti-slip convex part, and the telescopic ring is formed by wave troughs and wave crests arranged alternately in the axial direction. The anti-slip convex part is connected to a telescopic ring, which can also be flattened and elastically reset, so that the anti-slip convex part can move radially and telescopically, which is convenient for pipe docking. Moreover, the telescopic ring allows the socket section to bend in multiple directions at the telescopic ring, similar to the structure of a straw. And the telescopic ring is located on the side away from the port, and will not affect the sealing of the sealing ring when it is moving.

[0014] In some embodiments, a hollow cavity is provided in the socket section, the telescopic ring is integrally connected to the outer wall of the socket section and is located on the side of the port away from the socket section, the anti-slip teeth are also hollow structures communicating with the hollow cavity, and the anti-slip groove is provided on the inner wall of the socket section.

[0015] In some embodiments, the anti-slip protrusion is a plurality of anti-slip teeth arranged at intervals or a full circle of anti-slip waves.

[0016] In some embodiments, one of the bell section and the spigot section is provided with a sealing installation groove, in which a sealing ring is provided, and the sealing ring is used to seal and connect the bell section and the spigot section, and the sealing ring is located on the side of the port close to the spigot section. The sealing installation groove is used to install the sealing ring, and can prevent the sealing ring from shifting, and the sealing ring can play a role in sealing the pipeline.

[0017] In some embodiments, a sealing installation groove is provided on the socket section, a sealing ring is provided in the sealing installation groove, a sealing portion for extrusion sealing with the sealing ring is provided on the plug section, and an annular wave crest or annular wave trough is provided between the telescopic ring and the sealing portion.

[0018] In some embodiments, the anti-slip groove is a full-circle annular groove or two or more circumferentially spaced grooves.

[0019] The present application also provides a pipeline connection unit, characterized in that it includes a main body, on which the above-mentioned socket section and / or socket section are provided. The main body can be a pipe, such as a corrugated pipe, or a manhole. The two ends of the pipe can be provided with a socket section and a socket section respectively. Two types of pipes can also be provided. Both ends of the first type of pipe are provided with a socket section, while both ends of the second type of pipe are provided with a socket section, so that the two types of pipes can also be connected to each other. The main body, the socket section and the socket section are preferably formed in one piece.

[0020] It can be seen from the above technical solution that the present application has at least the following advantages and positive effects:

[0021] The present application provides a pipeline anti-dropout structure. When the spigot section and the socket section are butt-jointed, the anti-dropout protrusion can extend into the anti-dropout groove and snap into place with the groove, so that the pipeline has an anti-dropout capability and can effectively prevent the pipeline from being dropped out.

[0031] 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. The terms used in the implementation method 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 1

[0033] See also Figures 1 to 3 The present embodiment provides a corrugated pipe, which is made of plastic material, such as PP, PVC material. The corrugated pipe includes a body 8, and a socket section 1 and a bell section 2 are respectively provided at both ends of the body 8, and the bell section 2 can receive the socket section 1 of the adjacent pipe. The inner wall of the bell section 2 is provided with an anti-slip groove 4, and the socket section 1 is provided with an anti-slip convex portion. When two pipes are butt-jointed, the anti-slip convex portion can extend into the anti-slip groove 4 of the other pipe to be clamped therewith.

[0034] The anti-dropout protrusion is an elastic outward extension structure that can be radially expanded and contracted. When the socket section 1 and the socket section 2 are butted against each other, the anti-dropout protrusion is pressed and pushed to the position of the anti-dropout groove 4 in a radially contracted manner, and the anti-dropout protrusion enters the anti-dropout groove 4 in a radially expanded manner to form an axial contact limit. When the socket section 1 and the socket section 2 are butted against each other, the anti-dropout protrusion is first pressed and radially contracted, so that the anti-dropout part can be smoothly pushed to the position of the anti-dropout groove 4, and then the anti-dropout protrusion is elastically expanded and stuck in the anti-dropout groove 4. Such a pipeline installation structure is simple to install on site.

[0035] The anti-slip protrusion is an anti-slip tooth 3, and a telescopic ring 5 connected to the socket section 1 is integrally connected to the root of the anti-slip tooth 3. The telescopic ring 5 includes a plurality of trough rings 51 and crest rings 52 which are sleeved on the outer periphery of the anti-slip tooth 3. The trough rings 51 and the crest rings 52 are alternately arranged in concave and convex shapes and are sleeved one on the other, thereby forming a corrugated structure.

[0036] Since the root of the anti-slip teeth 3 is connected with a telescopic ring 5, when the socket section 1 and the socket section 2 are connected, the anti-slip teeth 3 are squeezed by the inner wall of the socket section 2 and radially contracted, and the trough ring 51 and the peak ring 52 of the telescopic ring 5 will be flattened. When the anti-slip teeth 3 reach the anti-slip groove 4, the elastic force of the material will drive the telescopic ring 5 to automatically reset, and the anti-slip teeth 3 will extend radially. The telescopic ring 5 is a multi-circle annular structure that is mutually sleeved, which can resist tension or pressure in multiple directions, play a buffering role, thereby protecting the pipe material, and can also reduce the occurrence of pipeline detachment. The pipeline is subjected to forces from multiple directions in the soil, especially at bends and during geological settlement. The pipeline structure with the telescopic ring 5 is particularly suitable for the above two situations.

[0037] The number of the anti-slip teeth 3 is two or more and they are arranged at intervals in the circumferential direction. Preferably, there are four anti-slip teeth 3 .

[0038] A hollow cavity 11 is provided in the socket section 1, the expansion ring 5 is integrally connected to the outer wall of the socket section 1, and the anti-slip teeth 3 are also hollow structures communicating with the hollow cavity 11. The hollow cavity 11 can reduce the material used in the socket section 1.

[0039] One of the socket section 2 and the spigot section 1 is provided with a sealing installation groove 6, in which a sealing ring 7 is provided, and the sealing ring 7 is used to seal and connect the socket section 2 and the spigot section 1. The sealing installation groove 6 is used to install the sealing ring 7, and can prevent the sealing ring 7 from shifting, and the sealing ring 7 can play a role in pipeline sealing.

[0040] The anti-slip groove 4 is a full-circle annular groove or two or more circumferentially spaced grooves.

[0041] The following briefly describes the working process and use method of a bellows in the above embodiment:

[0042] First, install the sealing ring 7 in the sealing installation groove 6. When the two corrugated pipes are butt-jointed, align the socket section 1 with the socket section 2 and insert it therein. The anti-slip teeth 3 are squeezed by the inner wall of the socket section 2, and the anti-slip teeth 3 radially sink and shrink, and the expansion ring 5 is flattened. When the anti-slip teeth 3 reach the position of the anti-slip groove 4, the anti-slip teeth 3 automatically reset and snap into the anti-slip groove 4 to form a snap connection. The sealing ring 7 is squeezed by the inner wall of the socket section 2 and the outer wall of the socket section 1 to seal the two pipes. When the pipelines are butt-jointed and buried in the soil, the anti-slip teeth 3 are a movable part. When subjected to a force, the socket section 1 will move relative to each other, thereby offsetting the external force.

[0043] Embodiment 2

[0044] See also Figure 4 Another embodiment of the present application is shown, and the main difference between this embodiment and the above embodiment is that the anti-dropping protrusion is arranged on the socket section 2.

[0045] Specifically, it is a corrugated pipe, including a body 8, with a spigot section 1 and a socket section 2 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 socket section 2 is provided with an anti-slip convex portion, and the outer wall of the spigot section 1 is provided with an anti-slip groove 4. When two pipes are butt-jointed, the anti-slip convex portion can extend into the anti-slip groove 4 of the other pipe to be clamped therewith.

[0046] The anti-slip protrusion is an anti-slip tooth 3, and a telescopic ring 5 connected to the socket section 2 is integrally connected to the root of the anti-slip tooth 3. The telescopic ring 5 includes a plurality of trough rings 51 and crest rings 52 which are sleeved on the outer periphery of the anti-slip tooth 3. The trough rings 51 and the crest rings 52 are alternately arranged in concave and convex shapes and are sleeved one on the other, thereby forming a corrugated structure.

[0047] The number of the anti-slip teeth 3 is two or more and they are arranged at intervals in the circumferential direction. Preferably, there are four anti-slip teeth 3 .

[0048] One of the socket section 2 and the spigot section 1 is provided with a sealing installation groove 6, in which a sealing ring 7 is provided, and the sealing ring 7 is used to seal and connect the socket section 2 and the spigot section 1. The sealing installation groove 6 is used to install the sealing ring 7, and can prevent the sealing ring 7 from shifting, and the sealing ring 7 can play a role in pipeline sealing.

[0049] The anti-slip groove 4 is a full-circle annular groove or two or more circumferentially spaced grooves.

[0050] Embodiment 3

[0051] See also Figures 5 and 6 Another embodiment of the present application is shown. The main difference between this embodiment and the first embodiment is that the telescopic ring is replaced by a telescopic ring, and the anti-slip component is a full-circle anti-slip wave.

[0053] An elastic universal joint is connected between the anti-slip protrusion and the socket section 1 or the socket section 2, and the anti-slip protrusion can move in multiple directions relative to the socket section 1 or the socket section 2 through the elastic universal joint.

[0054] The elastic universal joint is a telescopic ring 9 integrally connected to the root of the anti-slip convex part, and the telescopic ring 9 is formed by wave troughs and wave peaks arranged alternately in the axial direction. The anti-slip convex part is connected to the telescopic ring 9, which can also be flattened and elastically reset, so that the anti-slip convex part can move radially and telescopically, which is convenient for pipe docking. Moreover, the telescopic ring 9 can allow the socket section 1 to bend in multiple directions at the telescopic ring 9, similar to the straw structure. Moreover, the telescopic ring 9 is located on the side away from the port, and will not affect the sealing of the sealing ring 7 when it is active.
