Description

Technical Field

[0001] This utility model belongs to the field of water pipes, specifically relating to a quick-release water pipe connector. Background Technology

[0002] Quick-release water pipe connectors are widely used in agricultural irrigation, industrial water supply, and domestic water supply due to their convenient installation and rapid disassembly. Their sealing performance mainly depends on the stable fixation of the sealing ring in the connecting groove.

[0003] In traditional designs, the sealing ring is usually directly embedded into the sealing groove of the connector using a simple snap-fit, relying on the elastic deformation of the rubber material for initial positioning. It is fixed solely by the frictional resistance between the sealing ring and the groove. Under long-term scouring by high-pressure water or frequent disassembly and assembly, the sealing ring is prone to radial displacement or circumferential rotation, leading to seal failure and leakage. When the water pressure fluctuates, such as during start-up and shutdown due to the water hammer effect, the sealing ring may be dislodged from its initial position by the instantaneous impact force. This problem is particularly prominent in water transmission scenarios with large pipe diameters and high flow rates. In existing improvement solutions, some designs use adhesive bonding or metal snap rings for auxiliary fixation. However, the former makes it difficult to replace the sealing ring, while the latter increases structural complexity and manufacturing costs. Utility Model Content

[0004] To overcome the problem that the sealing ring of the water pipe connector does not fix well during use, which can easily affect the sealing effect of the water pipe, a quick-release water pipe connector is proposed.

[0005] The technical solution of this utility model is as follows: a quick-release water pipe connector, including a pipe structure, the pipe structure including upper and lower symmetrical fixed pipes, a connecting pipe fixedly connected to the two fixed pipes at their close ends, a groove opened at the edge of the two connecting pipes at their close ends, a sealing structure installed in the two grooves, the sealing structure including a sealing ring located in the groove, a number of equidistantly arranged fixed posts fixedly connected to the two sealing rings at their far ends, and equidistantly arranged groove holes opened on the inner wall of the two grooves at their far ends, the groove holes corresponding one-to-one with the fixed posts, the fixed posts and the groove holes being interference fit, the far ends of the fixed posts passing through the groove holes and fixedly connected with limit balls, the outer diameter of the limit balls being larger than the inner diameter of the groove holes.

[0006] Furthermore, the height of the sealing ring is greater than the depth of the groove, and the sealing ring, fixing post, and limit ball are all made of rubber.

[0007] Furthermore, the two sealing rings are fitted together at their closest ends, and four reinforcing ribs are fixed to the outer wall of the connecting pipe at equal intervals.

[0008] Furthermore, a connecting structure is installed on the outer wall of the connecting pipe, which includes a first fixing block and a second fixing block.

[0009] Furthermore, the outer wall of the connecting pipe located on the upper side is fixed with symmetrically distributed first fixing blocks, and the outer walls of the two first fixing blocks are fixed with first locking blocks extending clockwise, with the ends of the first locking blocks close to each other fixed to the outer wall of the connecting pipe on the upper side.

[0010] Furthermore, the outer wall of the connecting pipe located on the lower side is fixed with symmetrically distributed second fixing blocks, and the outer walls of the two second fixing blocks are fixed with second locking blocks extending counterclockwise, with the ends of the second locking blocks close to each other fixed to the outer wall of the connecting pipe on the lower side.

[0011] Furthermore, a first slot is provided at one end of the first fixing block that is close to each other, and the first slot is adapted to the second fixing block. A second slot is provided at one end of the second fixing block that is close to each other, and the second slot is adapted to the first fixing block.

[0012] The beneficial effects of this utility model are as follows: the groove can limit and fix the sealing ring; the equidistantly distributed fixing posts, in conjunction with the groove holes, can prevent the sealing ring from rotating and improve the stability of the sealing ring fixation; the diameter of the limiting ball is larger than the inner diameter of the groove hole, making it difficult for the limiting ball to pass through the groove hole, further improving the stability of the fixing posts. Compared with existing water pipe connectors, the added fixing post and limiting ball structure can improve the fixing effect of the sealing ring, prevent the sealing ring from loosening and rotating, and the limiting ball can improve the fixing effect of the fixing post, prevent the fixing post from retracting, ensure the sealing of the connected pipe, and facilitate the disassembly of the sealing ring.

[0020] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0021] Please see Figures 1-6 This utility model provides an embodiment: a quick-release water pipe connector, including a pipe structure 1, the pipe structure 1 including two symmetrical fixed pipes 101, each fixed pipe 101 having a connecting pipe 102 fixedly connected to one end close to the other, each connecting pipe 102 having a groove 104 at one edge close to the other, each groove 104 having a sealing structure 3 installed inside, each sealing structure 3 including a sealing ring 301 located inside the groove 104, each sealing ring 301 having a plurality of equidistantly arranged fixed posts 302 fixedly connected to one end far from the other, each groove 104 having equidistantly arranged slot holes 105 on the inner wall of one end far from the other, each slot hole 105 corresponding to one fixed post 302, the fixed post 302 and the slot hole 105 having an interference fit, the far end of the fixed post 302 passing through the slot hole 105 and fixedly connected to a limiting ball 303, the outer diameter of the limiting ball 303 being larger than the inner diameter of the slot hole 105.

[0022] The sealing ring 301 can be limited and fixed by the groove 104. The equally spaced fixing posts 302, in conjunction with the groove 105, can prevent the sealing ring 301 from rotating and improve the stability of the sealing ring 301. The diameter of the limiting ball 303 is larger than the inner diameter of the groove 105, making it difficult for the limiting ball 303 to pass through the groove 105, further improving the stability of the fixing posts 302. Thus, while facilitating the disassembly and replacement of the sealing ring 301, the stability of the sealing ring 301 is improved, thereby ensuring the sealing performance of the pipeline structure 1.

[0023] Please see Figure 3In this embodiment, the height of the sealing ring 301 is greater than the depth of the groove 104. The sealing ring 301, the fixing post 302, and the limiting ball 303 are all made of rubber. During use, the sealing ring 301 is higher than the groove 104, which allows the upper and lower connecting pipes 102 to form an interference fit, improving the sealing performance. The rubber sealing ring 301, fixing post 302, and limiting ball 303 can fit tightly against the groove 104 and the slot 105, and are easy to disassemble. The two sealing rings 301 are attached to each other at their closest ends. The outer wall of the connecting pipe 102 is fixed with four equidistant reinforcing ribs 103. During use, the sealing rings 301 fit together to ensure the sealing performance of the pipe structure 1. The reinforcing ribs 103 can improve the strength of the connecting pipe 102 and prevent it from being damaged by the pipe.

[0024] Please see Figures 4-5 In this embodiment, a connecting structure 2 is also installed on the outer wall of the connecting pipe 102. The connecting structure 2 includes a first fixing block 201 and a second fixing block 202. In use, the connecting structure 2 can connect the upper and lower connecting pipes 102 and facilitate the separation of the connecting pipes 102. The outer wall of the upper connecting pipe 102 is fixed with symmetrically distributed first fixing blocks 201. The outer walls of the two first fixing blocks 201 are fixed with clockwise extending first locking blocks 205. The ends of the first locking blocks 205 that are close to each other are fixed to the outer wall of the upper connecting pipe 102. In use, the first fixing blocks 201 can support the first locking blocks 205.

[0025] Please see Figures 4-6 In this embodiment, symmetrically distributed second fixing blocks 202 are fixed to the outer wall of the lower connecting pipe 102. Each of the two second fixing blocks 202 has a counter-clockwise extending second locking block 206 fixed to its outer wall. The ends of the second locking blocks 206 that are close to each other are fixed to the outer wall of the lower connecting pipe 102. In use, the second fixing blocks 202 can support the second locking blocks 206. The counter-clockwise distribution of the second locking blocks 206 avoids conflict with the clockwise extending first locking blocks 205. The ends of the first fixing blocks 201 that are close to each other are opened... There is a first slot 203, which is adapted to the second slot 206. The second fixing block 202 has a second slot 204 at one end that is close to each other, which is adapted to the first slot 205. In use, the connecting pipe 102 can be connected by the first slot 203 cooperating with the second slot 206 and the second slot 204 cooperating with the first slot 205. By rotating the connecting pipe 102, the first slot 203 slides out of the second slot 206 and the second slot 204 slides out of the first slot 205, and the connecting pipe 102 can be separated.

[0026] During operation, firstly, fix the two fixed pipes 101 to the two ends of the water pipe to be connected. Then, fit the two connecting pipes 102 together so that the sealing ring 301 fits tightly. Next, align the opening of the first slot 203 with one end of the second slot 206 and the opening of the second slot 204 with one end of the first slot 205. Rotate the connecting pipe 102 so that the first slot 203 engages with the second slot 206 and the second slot 204 engages with the first slot 205, thus completing the connection of the pipe. When the sealing ring 301 needs to be replaced, use a tool to cut the limiting ball 303 and pull out the sealing ring 301 directly. When the sealing ring 301 needs to be installed, align the fixing post 302 with the opening of the slot 105, press the sealing ring 301 to insert the fixing post 302 into the slot 105, and then fix the limiting ball 303 to the end of the fixing post 302 that extends out of the slot 105 with glue.

[0027] Through the above steps, the groove 104 can limit and fix the sealing ring 301. The equidistantly distributed fixing posts 302, in conjunction with the groove 105, can prevent the sealing ring 301 from rotating and improve the stability of the sealing ring 301. The diameter of the limiting ball 303 is larger than the inner diameter of the groove 105, making it difficult for the limiting ball 303 to pass through the groove 105, further improving the stability of the fixing posts 302. This solves the problem that the sealing gasket fixation effect is poor when the water pipe connector is used, which easily affects the sealing effect of the water pipe.
