Description

Technical Field

[0001] This utility model relates to the field of pipeline sealing technology, and in particular to a municipal pipeline sealing structure. Background Technology

[0002] Municipal pipelines refer to pipelines used in urban infrastructure to transport various fluids, including water supply pipelines for transporting domestic and industrial water, drainage pipelines for collecting and discharging rainwater and domestic sewage, and pipelines for transporting natural gas and liquefied petroleum gas, which have extremely high safety requirements. Their characteristics include being difficult to detect and being concealed. They should be able to reliably meet the needs of urban development, including the reliability of possible future expansion and renovation, and have good corrosion resistance, pressure resistance and wear resistance.

[0003] A search revealed Chinese Patent Publication No. CN213177155U, which discloses a municipal pipeline sealing structure, relating to the technical field of municipal engineering. This structure addresses the problem of difficult pipeline sealing construction. It includes a sealing ring and a metal ring. The sealing ring is elastic and fixedly installed at the connection point of the inner walls of two adjacent pipelines. The sealing ring has an inclined surface with a gradually decreasing diameter along the water flow direction on the side closest to the pipeline axis. The outer wall of the metal ring fits against the inclined surface, and the inner wall of the metal ring has a force-bearing surface with a gradually decreasing diameter along the water flow direction. The minimum diameter of the inclined surface is smaller than the minimum diameter of the force-bearing surface. This application can reduce the difficulty of pipeline sealing construction, solving the problem of reducing the difficulty of pipeline sealing construction. However, after the municipal pipeline is connected and sealed, if there are differences in elevation or subsequent geological changes, the connection point will be stretched, leading to a reduced service life and decreased practicality. Furthermore, when connecting and sealing pipelines of different diameters, different models of connection structures are required, increasing construction costs and reducing construction efficiency. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a municipal pipeline sealing structure, which aims to improve the problem that if there are differences in elevation or subsequent geological changes after the municipal pipeline is connected and sealed, the connection will be stretched, resulting in a reduced service life and decreased practicality.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a municipal pipeline sealing structure, comprising a first docking ring, wherein multiple arc grooves are provided on the right side of the first docking ring, a guide groove is provided on the inner wall of the arc groove, a guide rod is slidably connected to the inner wall of the guide groove, a second docking ring is fixedly connected to the left end of the guide rod, a positioning block 1 is fixedly connected to the top of both the second and first docking rings, a sliding block 1 is provided on the outer wall of the positioning block 1, a positioning block 2 is fixedly connected to the bottom of both the second and first docking rings, a sliding block 2 is provided on the outer wall of the positioning block 2, multiple screws 1 are threadedly connected to the inner walls of both the sliding block 2 and the sliding block 1, and an installation structure is fixedly connected to the opposite side of both the first and second docking rings, the installation structure being used to dock pipes of different sizes.

A second limiting sleeve is provided on the outer wall of the rotating plate. A first limiting sleeve is provided at the bottom of the second limiting sleeve. First fixing blocks are fixedly connected to the front and rear sides of the second limiting sleeve. Second fixing blocks are fixedly connected to the front and rear sides of the first limiting sleeve. A moving block is fixedly connected to the top of the second fixing block. A lead screw is threadedly connected to the inner wall of the moving block. A limiting plate is fixedly connected to the bottom end of the lead screw.

[0009] Through the above technical solution: the rotating shaft is used to support the rotating plate so that it can rotate along the rotating shaft, and the rotating plate can clamp the pipe that is slidably connected to its inner wall under the dynamic limitation of the second limiting sleeve and the first limiting sleeve. The screw can rotate, driving the moving block to move up and down, thereby pulling the second fixed block and the first limiting sleeve to move up and down.

[0011] Rubber pads are fixedly connected to adjacent sides of the plurality of rotating plates, and rubber rings are fixedly connected to the inner walls of the first limiting sleeve and the second limiting sleeve.

[0012] The above technical solution uses a rubber pad to cushion objects that come into contact with the rotating plate, preventing wear during clamping.

[0013] As a further description of the above technical solution:

[0014] A rotating disk is fixedly connected to the top of the lead screw, and multiple lead screws are threaded together at the same horizontal height.

[0017] The outer wall of the screw is provided with a washer, and the outer walls of the first and second mating rings are both provided with mounting grooves, and the inner wall of the mounting groove is slidably connected with a handle.

[0018] The above technical solution involves using a washer to increase the friction between the screw and the mounting surface, thereby preventing the screw from loosening after long-term use.

[0019] As a further description of the above technical solution:

[0020] Two screws are threadedly connected to the opposite side of the handle, and an anti-slip sleeve is fixedly connected to the outer wall of the handle.

[0021] The above technical solution utilizes the friction of the outer wall of the anti-slip sleeve to prevent the user from slipping out of their hand.

[0022] As a further description of the above technical solution:

[0023] The inner wall of the first docking ring is slidably connected to a connecting pipe, and a sealing ring is fixedly connected to the inner wall of the first docking ring near its edge.

[0024] Through the above technical solution, the second sealing ring is used to increase the sealing performance of the inner wall of the first mating ring.

[0025] As a further description of the above technical solution:

[0026] The inner wall of the second docking ring is slidably connected to a connecting pipe two, and a sealing ring one is fixedly connected to the inner wall of the second docking ring near the edge.

[0027] The above technical solution serves two purposes: firstly, to increase the friction of the inner wall of the second mating ring.

[0028] This utility model has the following beneficial effects:

[0029] 1. In this utility model, by inserting into the arc groove, and then rotating the second docking ring to make it slide into the guide groove, while aligning the sliding block 2 on the outer wall of the first docking ring with the sliding block 2 on the outer wall of the second docking ring, and finally twisting the shim to fix it, when the pipe is installed at different heights, the guide rod can slide up and down along the guide groove, while the first sliding block slides in the first positioning block, which achieves the purpose of buffering when there is a height difference at the pipe connection seal, extending the service life and improving practicality.

[0030] 2. In this utility model, by rotating the lead screw, the moving block is driven to pull the second fixed block up and down, which in turn works with the second limiting sleeve to squeeze the rotating plate, so that it can rotate along the rotating shaft, thereby achieving the purpose of connecting pipes of different diameters, speeding up construction efficiency and reducing construction costs.

A second docking ring 3 is fixedly connected to the left end of the guide rod 4. The guide grooves 5 and arc grooves 6 jointly guide the sliding of the guide rod 4. The second docking ring 3 and the first docking ring 1 can cooperate to connect the pipeline. Positioning blocks 8 are fixedly connected to the top of both the second docking ring 3 and the first docking ring 1. The outer wall of the positioning blocks 8 is provided with… There is a sliding block 9, and the bottom of the second docking ring 3 and the first docking ring 1 are fixedly connected to the positioning block 11. The positioning block 8 is used to guide the sliding block 9. The outer wall of the positioning block 11 is provided with a sliding block 10. The inner walls of the sliding block 10 and the sliding block 9 are threaded with multiple screws 7. The positioning block 11 is used to guide the sliding block 10. The opposite sides of the first docking ring 1 and the second docking ring 3 are fixedly connected to the mounting structure 2. The mounting structure 2 is used to dock pipes of different sizes. The screws 7 are used to connect the multiple sliding blocks 10 and the sliding block 9.

[0041] Specifically, the installation structure 2 can adapt to municipal pipes of different sizes and connect them. The arc groove 6 is used to ensure the sliding direction of the guide rod 4, so that it can slide into the guide groove 5 as the second docking ring 3 rotates. The sliding block 9 at the top of the second docking ring 3 and the first docking ring 1 can be aligned and fitted when the guide rod 4 enters the guide groove 5. At the same time, the sliding block 10 at the bottom of the guide rod 4 is aligned and fitted. At this time, the screw 7 can be used to fix them in pairs, thereby fixing the second docking ring 3 and the first docking ring 1 in place, ensuring the stability during installation, and also providing a buffer range for the structure after installation.

[0042] Please see the appendix Figure 2 - Appendix Figure 4 The mounting structure 2 includes a connecting ring 201, the outer wall of which is fixedly connected to the outer wall of the first mating ring 1. Multiple rotating shafts 202 are rotatably connected to the opposite side of the connecting ring 201. The connecting ring 201 provides a fulcrum for the installation of the rotating shafts 202. A rotating plate 208 is rotatably connected to the outer wall of the rotating shaft 202. A second limiting sleeve 210 is provided on the outer wall of the rotating plate 208, and a first limiting sleeve 207 is provided at the bottom of the second limiting sleeve 210.

The second limiting sleeve 210 and the first limiting sleeve 207 can limit the rotation angle of the multiple rotating plates 208. The moving block 205 can move up and down with the rotation of the lead screw 203, thereby pulling the second fixed block 209, which can drag the first limiting sleeve 207 up and down, thereby cooperating with the second limiting sleeve 210 to adjust the limiting of the rotating plate 208. The limiting plate 206 is used to prevent the first limiting sleeve 207 from exceeding its stroke and slipping off the lead screw 203, causing structural failure.

[0044] Please see the appendix Figure 3 - Appendix Figure 5Rubber pads 18 are fixedly connected to adjacent sides of multiple rotating plates 208. The rubber pads 18 are used to buffer the rotating plates 208 and the clamped objects. Rubber rings 17 are fixedly connected to the inner walls of the first limiting sleeve 207 and the second limiting sleeve 210. The rubber pads 18 are used to prevent the clamping of the rotating plates 208 from damaging the pipe. A screw 22 is threadedly connected to the opposite side of the handle 21. The screw 22 is used to fix the handle 21. An anti-slip sleeve 20 is fixedly connected to the outer wall of the handle 21. The handle 21 is used to help the user install the sealing structure and can be disassembled after completion. A washer 16 is provided on the outer wall of the screw 7. The washer 16 is used to increase the friction between the screw 7 and the contact surface. The outer walls of the first mating ring 1 and the second mating ring 3 are provided with mounting grooves 23. The inner wall of the mounting groove 23 is slidably connected to the handle 21. The mounting groove 23 is used to install the handle 21.

[0045] Specifically, the rubber pad 18 is used to prevent wear on the pipe when the rotating plate 208 clamps it, the rubber ring 17 is used to buffer the contact between the first limiting sleeve 207 and the second limiting sleeve 210 and the outer wall of the rotating plate 208, so that the first limiting sleeve 207 and the second limiting sleeve 210 will not damage the rotating plate 208 when limiting it, and the gasket 16 can reduce the friction between the screw 7 and the contact surface, thereby preventing the screw 7 from loosening after long-term use.

[0046] Please see the appendix Figure 4 - Appendix Figure 6 A rotating disk 19 is fixedly connected to the top of the lead screw 203. Multiple lead screws 203 are threaded together at the same horizontal height. A connecting pipe 2 13 is slidably connected to the inner wall of the second docking ring 3. A sealing ring 14 is fixedly connected to the inner wall of the second docking ring 3 near the edge. A connecting pipe 12 is slidably connected to the inner wall of the first docking ring 1. A sealing ring 2 15 is fixedly connected to the inner wall of the first docking ring 1 near the edge.

[0047] Specifically, the rotating disc 19 is used to help the user rotate the screw 203, the sealing ring 14 is used to increase the friction in the second docking ring 3, and the sealing ring 2 15 is used to increase the friction in the first docking ring 1. The connecting pipe 2 13 and the connecting pipe 1 12 are both municipal pipes used for connection.

[0048] Working principle: When connecting pipes, firstly, insert connecting pipe 12 and connecting pipe 2 13 into the first mating ring 1 and the second mating ring 3 respectively, and make them fit with sealing ring 2 15 and sealing ring 14 respectively. Then, insert the guide rod 4 into the arc groove 6, and then rotate the second mating ring 3 so that the guide rod 4 can slide into the guide groove 5. At the same time, the arc groove 6 and sliding block 2 10 on the upper and lower sides of the first mating ring 1 and the second mating ring 3 are aligned respectively. Then, turn screw 1 7 to fix them together. When the pipe is placed in an uneven buried pipe trench, with one side higher than the other, the guide rod 4 slides in the guide groove 5, while the arc groove 6 slides in the positioning block 1 8, and the sliding block 2 10 slides in the positioning block 2 11, which provides buffering and avoids loosening of the connection due to long-term installation.

[0049] When pipes of different diameters need to be connected, they are first inserted into the connecting ring 201 at one end. Then, the screw 203 is rotated so that the moving block 205 on its outer wall can move on it, thereby pulling the second fixed block 209 and the first limiting sleeve 207 to move up and down. By squeezing the rotating plate 208, it is made to rotate along the rotating shaft 202, thereby installing pipes of different diameters.
