Description

Technical Field

[0001] This utility model relates to the field of water supply pipeline technology, specifically to a seepage-proof structure for a rubber ring on a municipal water supply pipeline joint. Background Technology

[0002] Prestressed steel cylinder concrete refers to a water pipe made by winding circumferential prestressed steel wires around a high-strength concrete core with a steel cylinder, and then spraying a dense cement mortar protective layer on it. It is commonly used in water conservancy pipelines. However, current technology has revealed at least the following technical problems during implementation: During rapid connection and installation, it is difficult to ensure that the sealing rings of the pipe can fit tightly. In addition, with long-term use, the pressure on the inner wall of the pipe will continuously impact the sealing rings, which can easily lead to damage to the sealing rings. In this case, the water inside the pipe will flow out and seep into the outside of the pipe, affecting the safety of use.

[0003] To address the aforementioned technical issues, Chinese Patent No. CN220551650U discloses a PCCP pipe joint rubber ring anti-leakage structure, comprising a fixedly installed pipe body, a first arc-shaped plate movably installed at the side end of the pipe body, a second arc-shaped plate movably installed at the bottom end of the first arc-shaped plate, two second clamping blocks fixedly installed on the surface of the second arc-shaped plate, and an annular groove formed at the side end of the pipe body.

[0004] Although the existing technical solution described above can replace either the first or second arc plate individually, reducing maintenance and replacement costs, it requires workers to rotate each set of handles one turn at a time to allow the threaded rod to rotate with the thread in order to complete the disassembly and assembly operation when locking or disassembling the first or second arc plate.

[0021] Example:

[0022] Please see Figures 1-3 This utility model provides a technical solution:

[0023] A leak-proof structure for a municipal water supply pipe joint includes a pipe body 1. A sealing groove is provided at the end of the pipe body 1. Two sets of first sealing sleeves 2 are engaged and connected inside the sealing groove. A connecting plate is installed on one side of each first sealing sleeve 2, and a second sealing sleeve 4 is installed on the other end of the connecting plate. An installation frame 3 is installed on the outside of each second sealing sleeve 4. The two sets of installation frames 3 are locked together by a pressing mechanism. The pressing mechanism includes a docking component, a rotary pressing component, an abutting component, and a protective component. The docking component is used to initially dock the two sets of installation frames 3. The rotary pressing component is used to cooperate with the docking component to unlock the positions of the two sets of installation frames 3. The connecting component is used to lock the positions of the two sets of mounting frames 3 in conjunction with the rotating component. The protective component is used to cover the operating end of the rotating extrusion component for protection. When using this device, the two sets of mounting frames 3 can be initially connected by the connecting component. The rotating extrusion component unlocks the positions of the two sets of mounting frames 3 in conjunction with the connecting component. The abutting component locks the positions of the two sets of mounting frames 3 in conjunction with the rotating component. The protective component covers the operating end of the rotating extrusion component for protection. The structure is simple and the operation is convenient. The operator can quickly disassemble and assemble the device by pressing and twisting, which reduces the workload of the operator and improves the efficiency of replacement and maintenance.

[0024] In this embodiment, as Figure 1 , Figure 2 and Figure 3As shown, the docking assembly includes a fixed seat 6 installed on one side of the outer wall of one set of mounting frames 3. A movable rod is slidably connected inside the fixed seat 6. A rotating groove is opened inside the fixed seat 6 on the outside of the movable rod. A rotating plate 5 is slidably connected inside the rotating groove. The rotating plate 5 is rotatably connected to the movable rod. A first spring is installed between the two ends of one side of the rotating plate 5 and the inner wall of the rotating groove. A retraction groove is opened at the bottom of the fixed seat 6 on the outside of the movable rod. A locking block 7 is installed at one end of the movable rod. An mounting seat 20 is installed on one side of the outer wall of the other set of mounting frames 3. A docking groove 8 is opened at the top of the mounting seat 20. The docking groove 8 is a cross groove. A locking block 7 is installed at one end of the movable rod. The horizontal opening and the vertical opening of the docking groove 8 are slidably connected to the locking block 7. First, after the two sets of mounting frames 3 are attached, the first sealing sleeve 2 is inserted into the inner side of the sealing groove, so that the inner side of the second sealing sleeve 4 is attached to the outer wall of the pipe joint. At the same time, the pull ring 18 can be fastened to drive the movable rod to move down, thereby driving the rotating plate 5 to stretch the first spring.

[0025] In this embodiment, as Figure 1 , Figure 2 and Figure 3 As shown, the rotary extrusion assembly includes a mounting groove located inside the mounting base 20 on one side of the docking groove 8. A base 9 is rotatably connected to the inside of the mounting groove. A second spring is installed at both ends of the top of the base 9. A docking plate 10 is installed at the top of the second spring. A positioning block 11 is installed at the top of the docking plate 10. A positioning groove that engages with the positioning block 11 is opened at the bottom of the locking block 7. The abutment assembly includes abutment grooves 12 located inside the mounting base 20 on both sides of the mounting groove. A third spring is installed inside the abutment groove 12. An abutment block 13 is installed at one end of the third spring. The abutment block 13 is engaged with the abutment groove 12. A fixing block is installed at both ends of the top of the locking block 7. The bottom end of the fixing block 14 and the abutment block 13 has a fixing groove that engages with the fixing block 14. Then, the two ends of the locking block 7 contact the abutment blocks 13 on both sides, and the inclined surfaces of the two contacts each other. The abutment block 13 is squeezed back and drives the third spring to retract. After the locking block 7 and the fixing block 14 installed on it continue to move downward and offset the abutment block 13, the abutment block 13 is popped out by the third spring. At this time, the positioning block 11 is locked into the positioning groove. After continuing to move downward, it compresses the second spring of the mating plate 10 and retracts. Then it is pulled back a distance, and the fixing block 14 is locked into the inside of the fixing groove. The abutment block 13 and the mating plate 10 press the locking block 7 together, thus completing the position locking of the two sets of mounting frames 3.

[0026] In this embodiment, as Figure 1 , Figure 2 and Figure 3As shown, the interior of the fixed base 6 has an extension groove on one side of the rotating groove. The movable rod extends to one end of the extension groove and is rotatably connected to a pull ring 18. Both ends of the locking block 7 and the opposite ends of the two sets of abutment blocks 13 are provided with inclined surfaces. The side cross section of the locking block 7 is T-shaped. The two sets of inclined surfaces fit together. Furthermore, by holding the pull ring 18 and pushing it down again, in conjunction with the positioning block 11 and the positioning groove, the mating plate 10 and the first spring can be moved down together again. Then, in conjunction with the base 9, it rotates and after the abutment block 13 is displaced, the pull ring 18 is loosened back. The locking block 7 can then be pulled out along the transverse opening of the mating groove 8 and moved to the inside of the retraction groove. At this time, by holding the outside of the fixed base 6 and pulling it out, the two sets of fitting mounting frames 3 can be separated, allowing old or damaged parts to be replaced or maintained. The mating groove 8 is a cross groove, and the mounting grooves are all circular grooves.

[0027] In this embodiment, as Figure 1 , Figure 2 and Figure 3 As shown, the protective assembly includes a closed groove 15 located on the top of the fixed base 6 on one side of the extension groove. A closed plate 16 is slidably connected to the inside of the closed groove 15. A snap-pull groove is provided on one side of the closed plate 16. A limiting groove extending to the inner wall of the extension groove is provided on one side of the inner wall of the closed groove 15. A limiting block 17 slidably connected to the limiting groove is installed on one side of the closed plate 16. A first fixing member 19 is embedded in one end of the closed plate 16. A second fixing member corresponding to the first fixing member 19 is embedded in the inner wall of the closed groove 15. One of the first fixing member 19 and the second fixing member is a first magnet, and the other of the first fixing member 19 and the second fixing member is a second magnet. The magnetic poles of the first magnet and the second magnet are opposite and attract each other. Furthermore, the snap-pull groove allows the limiting block 17 to move the closed plate 16 along the limiting groove inside the closed groove 15 until it moves to the inside of the extension groove, so that the first fixing member 19 and the second fixing member are attracted to each other and cover the pull ring 18, so as to prevent the component from being loosened by personnel accidentally touching it after assembly.

[0028] The implementation principle of the anti-seepage structure of the rubber ring of the municipal water supply pipe joint in this application embodiment is as follows: After the two sets of mounting frames 3 are attached, the first sealing sleeve 2 is inserted into the inner side of the sealing groove, and the inner side of the second sealing sleeve 4 is attached to the outer wall of the pipe joint. At the same time, the pull ring 18 can be fastened to drive the movable rod to move down, which drives the rotating plate 5 to stretch the first spring. The two ends of the locking block 7 contact the abutment blocks 13 on both sides. The inclined surfaces of the two contact each other, and the abutment block 13 is squeezed back and drives the third spring to retract. After the locking block 7 and the fixed block 14 installed on it continue to move down and offset the abutment block 13, the abutment block 13 is popped out by the third spring. At this time, the positioning block 11 is inserted into the positioning groove. After continuing to move down, it compresses the second spring of the docking plate 10 and retracts. Then it is pulled back a distance, and the fixed block 14 is inserted into the inner side of the fixing groove. The abutment block 13 and the docking plate 10 press the locking block 7 tightly. The positions of the two sets of mounting frames 3 are locked. The pull ring 18 is pulled down again. With the help of the positioning block 11 and the positioning groove, the mating plate 10 and the first spring can be moved down together again. Then, with the help of the base 9, the pull ring 18 is loosened back after the abutment block 13 is offset. The locking block 7 can then be pulled out along the horizontal opening of the mating groove 8 and moved to the inside of the retraction groove. At this time, the outside of the fixing seat 6 is held and pulled to separate the two sets of mating mounting frames 3. Old or damaged parts can be replaced or maintained. The mating groove 8 is a cross groove, and the mounting grooves are all circular grooves. The locking groove allows the limiting block 17 to drive the closing plate 16 to move along the limiting groove inside the closing groove 15 until it moves to the inside of the extension groove. This allows the first fixing part 19 and the second fixing part to be attracted and cover the pull ring 18 to prevent the parts from being loosened by personnel accidentally touching them after assembly.

[0029] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
