Description

Technical Field

[0001] The utility model relates to the technical field of pipe connection, in particular to a socket-and-spigot structure of a pipe. Background Art

[0002] In the field of pipeline engineering, the connection method of pipes is crucial to the stability, sealing, and reliability of the pipeline system. As a common pipe connection method, the socket-and-spigot structure is widely used in various types of pipeline systems due to its advantages such as quick installation, good sealing, low material cost, and wide application range. Therefore, it is necessary to use this structure.

[0003] The existing pipe socket structure is designed through the shape of the socket and the spigot. The socket is usually designed as a cylindrical structure with a certain depth and inner diameter, and the spigot is designed as a cylindrical structure that matches the socket. When the spigot is inserted into the socket, the protrusion and the groove cooperate with each other to connect the socket and the spigot. In order to ensure the sealing of the socket connection, an anti-slip sealing structure is usually set in the socket.

[0004] The existing technology has the problem that an anti-slip sealing structure needs to be set in the socket, which results in relatively large sliding resistance, low connection operation efficiency, inconvenient operation during socket insertion, and a long time consumption. In addition, the existing technology is prone to loosening of the pipe after socket insertion, and the socket interface is not tight, which causes the pipe to fall off easily after use for a period of time. Utility Model Content

[0005] In order to make up for the above deficiencies, the utility model provides a socket-and-spigot structure for pipes, aiming to improve the problems of low connection efficiency of pipes during socket-and-spigot connection and easy loosening of pipes after socket-and-spigot connection.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a socket structure of a pipe, comprising a socket pipe, the socket pipe is fixedly connected with a plug plate, the plug plate is slidably connected with a plug block 2, one end of the plug block 2 is fixedly connected with the socket pipe, the inner wall of the socket pipe is provided with a socket component, the outer wall of the socket pipe is provided with a limiting component, the socket component comprises a plug block 1, the outer wall of the plug block 1 at one end is fixedly connected to the inner wall of the socket pipe, the plug block 1, the outer wall of the socket pipe is fixedly connected with a slot block, the outer wall of the socket pipe is fixedly connected with a fixing block, the outer wall of the fixing block is slidably connected with a slide, one end of the slide is provided with a spring 1, a steel ball is provided inside the socket pipe, the outer wall of the steel ball is slidably connected to the inside of the socket pipe, the outer wall of the socket pipe is provided with a slot, and the outer wall of the plug block 1 is slidably connected to the inner wall of the slot.

[0007] Furthermore, the limiting assembly includes a limiting ring, and the inner wall of the limiting ring is fixedly connected to the outer wall of the socket pipe.

[0008] Furthermore, the inner wall of the socket pipe is fixedly connected to a sealing ring 1, the outer wall of the plug pipe is provided with a sealing assembly, the sealing assembly includes a sealing ring 2, the inner wall of the sealing ring 2 is fixedly connected to the outer wall of the plug pipe, the outer wall of the plug pipe is fixedly connected to a connecting block, and the outer wall of the socket pipe is fixedly connected to a base 1.

[0009] Furthermore, the base one is slidably connected to the base two, the base two is provided with a spring two, the base two is provided with a steel ball, the outer wall of the steel ball is slidably connected to the base one, the outer wall of the base two is fixedly connected to the sealing ring three, and the inner wall of the sealing ring three is slidably connected to the socket pipe.

[0010] Furthermore, one end of the spring is fixedly connected to the inner wall of the slide plate, and the other end of the spring is fixedly connected to one side of the outer wall of the fixed block.

[0011] Furthermore, the outer wall of the spigot pipe is fixedly connected to the inner wall of the socket pipe.

[0012] Furthermore, one side of the inner wall of the slide plate is slidably connected to the outer wall of the socket pipe.

[0013] Furthermore, one end of the second spring is fixedly connected to the outer wall of the steel ball, and the other end of the second spring is fixedly connected to the inside of the second base.

[0014] Furthermore, an inner wall of the sealing ring is slidably connected to the outer wall of the socket pipe.

[0015] Furthermore, the second outer wall of the sealing ring is slidably connected to the inner wall of the socket pipe.

[0016] The utility model has the following beneficial effects:

[0017] 1. In the utility model, the sliding slide compresses spring 1, so that the steel ball expands outward, the socket pipe is inserted into the socket pipe, and the plug block 2 is inserted into the plug plate inside the socket pipe. At the same time, the plug block 1 in the socket pipe is inserted into the internal slot of the plug pipe to realize the rapid connection between the socket pipe and the socket pipe, thereby improving the connection efficiency. When the slide is released, spring 1 is reset to make the slide squeeze the steel ball, so that the steel ball shrinks to the inside of the socket pipe and clamps the slot block, thereby making the connection between the socket pipe and the socket pipe more precise, improving the stability of the pipe connection, and avoiding the problem of pipe falling off due to long-term use.

[0018] 2. In the utility model, a sealing ring 1 is provided inside the socket pipe. Since the diameter of the front end of the plug pipe is smaller than the diameter of the sealing ring 1, compared with the prior art, the plug pipe can pass through the sealing ring 1 smoothly while the inside of the pipe can be sealed, thereby improving the tightness of the pipe connection. During the insertion of the plug pipe into the socket pipe, the base 2 is inserted into the base 1, and the steel ball is squeezed and contracted by the base 1, compressing the spring 2. When the steel ball moves to the internal groove of the base 1, the spring 2 is reset, and the steel ball is stuck in the groove of the base 1. At the same time, the sealing ring 3 seals the interface between the socket pipe and the connecting block, thereby preventing sand, gravel and dust from entering the socket of the pipe during the connection process.

[0027] Reference Figures 1-4The inner wall of the socket pipe 1 is fixedly connected with a sealing ring 13, which is used to seal the inside of the pipe. The outer wall of the spigot pipe 10 is provided with a sealing component, which includes a sealing ring 2 14. The sealing ring 2 14 further improves the sealing performance of the inside of the pipe. The inner wall of the sealing ring 2 14 is fixedly connected to the outer wall of the spigot pipe 10.

[0028] Working principle: When it is necessary to connect the pipes, first slide the slide plate 4 to compress the spring 15 so that the steel ball 9 expands to the outside of the socket pipe 1, then insert the socket pipe 10 into the socket pipe 1, and connect it with the plug plate 2 inside the socket pipe 1 through the plug block 2, and at the same time insert the plug block 16 inside the socket pipe 1 into the slot 12 inside the plug pipe 10. In this way, the socket pipe 1 and the socket pipe 10 are quickly connected, which improves the connection efficiency. Then release the slide plate 4 to reset the spring 15, drive the slide plate 4 to slide downward to squeeze the steel ball 9, so that the steel ball 9 expands to the socket pipe The inner part of the pipe 1 shrinks and is stuck in the card slot block 8. In this way, the tightness of the connection between the socket pipe 1 and the spigot pipe 10 is increased to avoid falling off due to long-term use of the pipe. A sealing ring 13 is set inside the socket pipe 1 to increase the sealing inside the pipe. Since the diameter of the front end of the spigot pipe 10 is smaller than the diameter of the sealing ring 13, the spigot pipe 10 can easily pass through the sealing ring 13, so that the resistance during the socket and plugging is small. Similarly, a sealing ring 2 14 is set on the outer wall of the spigot pipe 10 to further increase the sealing inside the pipe after the socket and plugging. The diameter of the socket pipe 1 is larger than the diameter of the sealing ring 2 14 and slightly smaller than the outer diameter of the sealing ring 2 14, so the resistance encountered during the socket is also relatively small, and the tightness of the pipe interior is further increased while reducing the resistance. In the process of inserting the spigot pipe 10 into the socket pipe 1, the base 2 17 is inserted into the base 1 16, and the steel ball 19 inside the base 2 17 is squeezed and contracted by the inner wall of the base 16, compressing the spring 2 18. When the steel ball 19 moves to the slot of the base 16, the spring 2 18 resets, so that the steel ball 19 is stuck in the slot of the base 16, and at the same time the sealing ring 3 20 presses the socket pipe 1 is sealed at the interface with the connecting block 15. In this way, the sealing of the interface is achieved to prevent sand, gravel and dust from entering the socket of the pipe during the connection process. Similarly, when disassembly is required, the steel ball 19 is pressed to make the steel ball 19 shrink toward the inside of the base 2 17, and the steel ball 19 is separated from the slot of the base 1 16. At the same time, the sliding slide 4 compresses the spring 1 5, so that the steel ball 9 is separated from the slot block 8 and expands toward the outside of the socket pipe 1. Then, the connecting block 15 is pulled to separate the socket pipe 10 from the socket pipe 1, and the base 2 17 is separated from the base 1 16. In this way, the pipe can be quickly disassembled.
