Description

Technical Field

[0001] This utility model relates to the field of PE water supply pipe technology, and in particular to a socket connection structure for PE water supply pipe. Background Technology

[0002] The socket-type connection structure of PE water supply pipes is a common and widely used pipe connection method, mainly used in water supply, drainage, and agricultural irrigation. Polyethylene (PE) pipes have become the preferred material for many urban water supply and water conservancy projects due to their advantages such as corrosion resistance, wear resistance, lightweight, and ease of installation. The socket-type connection simplifies the installation process and improves construction efficiency by inserting the pipe spigot into the socket and using a sealing ring to ensure water tightness. Its advantages include easy installation, reliable sealing, strong seismic resistance, good corrosion resistance, high disassembly capability, and strong adaptability, especially maintaining connection stability under earthquakes or external forces. Socket-type connections are widely used in urban water supply networks, pipeline renovation, and rural drinking water projects, especially suitable for small and medium diameter PE pipe systems. Due to their low cost, convenient construction, and simple maintenance, they have become an indispensable and important component of modern water supply pipeline systems.

[0003] However, in actual use of existing solutions, the connection structure typically uses bolts to tighten the clamps. This requires specialized tools (such as wrenches) to ensure the bolts are secure, and the bolts need to be rotated each time the pipeline is disassembled or reassembled. This increases the equipment requirements during construction and may also increase construction costs and resource consumption.

[0004] Therefore, this utility model provides a socket connection structure for PE water supply pipes. Utility Model Content

[0005] The purpose of this utility model is to solve the problem that in the existing technology, the clamps are tightened by bolts, and tools are needed to rotate the bolts every time the pipe is disassembled or assembled. This increases the equipment requirements during construction and may also increase construction costs and resource consumption. Therefore, a socket connection structure for PE water supply pipes is proposed.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A socket connection structure for a PE water supply pipe includes a clamp, a first support base is fixedly connected to the front side of the top of the clamp, a fixing frame is fixedly connected to the top of the first support base, a second support base is fixedly connected to the rear side of the top of the clamp, and a locking component is provided at the top of the second support base.

[0008] Preferably, the engaging assembly includes a limiting frame, the limiting frame is fixedly connected to the top of the second support base, a transmission frame is rotatably connected to the front side of the top of the limiting frame, a transmission rod is rotatably connected to the inner side of the bottom of the transmission frame, an engaging rod is slidably connected to the inner side of the transmission rod, and a bolt with opposite bolts is threaded to the outer rear side of the engaging rod, and the engaging rod is engaged with the fixed frame.

[0009] Preferably, the inner side of the clamp is fixedly connected with left and right opposing sealing rings.

[0010] Preferably, a fixing ring is fixedly connected to one end of the inner side of the clamp, and a connecting pipe is fixedly connected to the inner side of the fixing ring.

[0011] Preferably, a sealing groove is provided at the outer end of the connecting pipe, and an inner liner is fixedly connected to the inner end of the connecting pipe.

[0012] Preferably, an outer ball is fixedly connected to the right side of the connecting tube on the left, and an inner ball is rotatably connected to the inner side of the outer ball, and the inner ball is fixedly connected to the connecting tube on the right.

[0013] Compared with the prior art, this utility model provides a socket connection structure for PE water supply pipes, which has the following advantages:

[0014] This utility model discloses a socket-type connection structure for PE water supply pipes. By pre-adjusting the position of the bolts, the diameter of the clamp can be adjusted, thereby improving the applicability of the device. At the same time, by opening a sealing groove and cooperating with the sealing ring, the clamp and the PE pipe are sealed. Simultaneously, the fixing frame is locked by the locking rod, and the two sides of the clamp are tightened to complete the fixation. After one adjustment, the PE pipe can be fixed simply by pulling the transmission frame.

[0015] This utility model discloses a socket-type connection structure for PE water supply pipes. The adjustable angle between the outer and inner spheres allows for adaptation to pipe layout requirements in different directions and angles, particularly in complex pipe installation environments. Adjusting the angle facilitates efficient pipe arrangement without the need for additional elbows or connectors, simplifying construction design. It also effectively avoids unnecessary bending and stress concentration, especially where pipe direction changes are required. This reduces fluid friction loss due to excessive bending and lowers the risk of cracking or damage at pipe connections caused by stress concentration. Attached Figure Description

All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model. Example

[0024] Reference Figure 1-5 A socket connection structure for a PE water supply pipe includes a clamp 1. A first support seat 12 is fixedly connected to the front top of the clamp 1, and the clamp 1 supports and fixes the first support seat 12. A fixing frame 13 is fixedly connected to the top of the first support seat 12, and the first support seat 12 supports and fixes the fixing frame 13, thereby providing a stress point on one right end of the clamp 1. A second support seat 14 is fixedly connected to the rear top of the clamp 1, and the clamp 1 supports and fixes the second support seat 14. A locking component is provided at the top of the second support seat 14.

[0025] The engaging assembly includes a limiting frame 15. The limiting frame 15 is fixedly connected to the top of the second support base 14, which supports and fixes the limiting frame 15. A transmission frame 16 is rotatably connected to the front side of the top of the limiting frame 15, which limits the middle front side of the transmission frame 16, allowing the transmission frame 16 to rotate around the connection point between the transmission frame 16 and the limiting frame 15. A transmission rod 17 is rotatably connected to the inner side of the bottom of the transmission frame 16, which limits the transmission rod 17. An engaging rod 18 is slidably connected to the inner side of the transmission rod 17, which limits both ends of the engaging rod 18. The outer rear end of the engaging rod 18 is threaded with opposing bolts 19, which are fixed to both sides of the engaging rod 18, thus fixing the relative position between the engaging rod 18 and the transmission rod 17. The engaging rod 18 is engaged with the fixing frame 13, and the height of the transmission rod 17 is lower than the connection point between the limiting frame 15 and the transmission frame 16.

[0026] The inner side of the clamp 1 is fixedly connected with left and right opposing sealing rings 11. The clamp 1 fixes the sealing rings 11, and the sealing rings 11 can seal the clamp 1 and the PE pipe to prevent leakage between the PE pipe and the connection structure.

[0027] A fixing ring 25 is fixedly connected to the inner side of the clamp 1. The clamp 1 fixes the fixing ring 25. A connecting pipe 2 is fixedly connected to the inner side of the fixing ring 25. The fixing ring 25 fixes the connecting pipe 2. The clamp 1 and the connecting pipe 2 are connected through the fixing ring 25. A quarter-inch notch is provided on the front side of the top of the fixing ring 25.

[0028] A sealing groove 21 is provided at the outer end of the connecting pipe 2. The PE pipe can be engaged through the sealing groove 21, thereby connecting the connecting pipe 2 and the PE pipe and increasing the sealing performance. An inner liner 22 is fixedly connected to the inner end of the outer side of the connecting pipe 2. The inner liner 22 is fixed through the connecting pipe 2. The inner liner 22 is inserted into the PE pipe to provide support for the PE pipe. This avoids deformation of the PE pipe due to the tightening of the clamp 1 when fixing the PE pipe, and provides support and stress for the PE pipe.

[0029] An outer ball 24 is fixedly connected to the right side of the left connecting pipe 2. An inner ball 23 is rotatably connected to the inner side of the outer ball 24. The inner ball 23 is fixedly connected to the right connecting pipe 2. The inner ball 23 and the outer ball 24 are fixedly connected to the same connecting pipe 2, and the outer side of the connecting pipe 2 is provided with the same structure. The outer ball 24 can rotate outside the inner ball 23, thereby adjusting the angle between the two connecting pipes 2 to improve the applicability of the device.

[0030] Working principle:

[0031] This utility model discloses a socket-type connection structure for PE water supply pipes. In use: First, insert the PE pipe into the clamp 1 and then insert the inner liner 22 into the PE pipe. Next, move the PE pipe inwards until it engages with the sealing groove 21, thus completing the connection between the connecting pipe 2 and the PE pipe. Then, by rotating the connecting pipe 2, the inner ball 23 can rotate inside the outer ball 24, thereby adjusting the angle of the connecting pipes 2 at both ends. Then, insert the inner liner 22 at the other end into the PE pipe on the other side, engaging the PE pipe with the sealing groove 21. After the connecting pipes 2 and PE pipes on both sides are fixed, rotate the transmission frame 16 backwards, allowing the transmission frame 16 to rotate around the limit... The connection point between the mounting brackets 15 is rotated, thereby driving the transmission rod 17 to move obliquely upward through the transmission bracket 16, and driving the locking rod 18 to move synchronously, thus canceling the engagement with the fixed bracket 13. Then, the bolts 19 on both sides are rotated and adjusted to the corresponding positions. The locking rod 18 is then re-sleeved onto the outside of the fixed bracket 13. Then, the transmission bracket 16 is pulled forward and obliquely downward, while the transmission rod 17 moves synchronously through the transmission bracket 16, and the locking rod 18 moves obliquely downward through the transmission rod 17, thereby engaging the locking rod 18 with the fixed bracket 13, thus tightening both sides of the clamp 1. At the same time, the top front side of the clamp 1 is moved backward, thus completing the fixation and sealing between the clamp 1 and the PE pipe.

[0032] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
