Description

TECHNICAL FIELD

[0001] The utility model relates to water pipe connecting technical field especially relates to a sleeve type water supply and drainage pipe connecting structure of anti -settlement. BACKGROUND

[0002] The sleeve is usually made of metal material, such as ductile cast iron or stainless steel, and has high strength and corrosion resistance. Its shape is a hollow cylinder, and its inner diameter is slightly larger than the outer diameter of the water supply and drainage pipe, so that it can be fitted on the pipe. The length of the sleeve is determined according to actual needs to provide sufficient connection and protection area. At the connection with the water supply and drainage pipe, a sealing rubber ring is provided. The rubber ring has good elasticity and aging resistance, such as EPDM. The cross-sectional shape of the rubber ring is usually circular or rectangular. Its inner diameter closely matches the outer diameter of the pipe, and its outer diameter matches the inner diameter of the sleeve. By extruding and deforming the rubber ring, the pipe and the sleeve are sealed to prevent water leakage.

[0003] When the pipe settles, the sealing rubber ring between the sleeve and the pipe first acts as a buffer. The elastic deformation of the rubber ring can absorb part of the displacement and stress caused by settlement, avoiding rigid collision and damage between the pipe and the sleeve. At the same time, the sleeve and the pipe are not completely fixed, but allow a certain relative sliding and rotation. However, without the existing disassembly design, when the water supply and drainage pipe has problems such as blockage, rupture or leakage, it is difficult to directly contact the problem area for inspection and repair because the sleeve type connecting structure cannot be disassembled. This makes it difficult to accurately find the leakage point by disassembling the connecting structure. It may be necessary to excavate a larger range of soil around the pipe to check, increasing the maintenance cost and time. SUMMARY

[0004] To make up for the above shortcomings, the utility model provides a sleeve type water supply and drainage pipe connecting structure with anti-settlement function, which aims to improve the problem that in the prior art, without the existing disassembly design, when the water supply and drainage pipe has problems such as blockage, rupture or leakage, it is difficult to directly contact the problem area for inspection and repair because the sleeve type connecting structure cannot be disassembled.

Two external threads 12 are provided on the left and right sides of the outer wall of the connecting pipe 11, and a waterproof strip 1 is provided on the outer wall of the external threads 12. 3. The outer wall of the external thread 12 is connected to the inner thread of the corresponding internal thread 15. Holes 10 are opened around the inner sides of the flange 1 and the C-shaped protective strip 8. High-leg bolts 9 are installed inside the holes 10. Nuts 3 are threaded to the right side of the outer wall of the high-leg bolts 9.

Sealing rings 14 are fixedly connected to the left and right sides of the outer wall of the connecting pipe 11. The outer wall of the sealing ring 14 is in contact with the outer side of the corresponding column water pipe 16 and the column water pipe 2.

[0032] Specifically, it is connected to flange 25 via a connector. Similarly, the middle left side of column water pipe 217 is also connected to flange 11 via a connector. Both column water pipes, namely column water pipe 16 and column water pipe 217, have internal threads 15 on one side to facilitate threaded connection with other components. A connecting pipe 11 is installed at the adjacent positions of column water pipe 16 and column water pipe 17. Two external threads 12 are opened on the left and right sides of the outer wall of the connecting pipe 11. In order to ensure the sealing of the connection, a waterproof strip 13 is specially provided on the outer wall of the external thread 12. The external thread 12 of the connecting pipe 11 is threadedly connected to the internal thread 15 of column water pipe 16 and column water pipe 17 to ensure the firmness of the connection. Holes 10 are opened on the inner sides of flange 1 and C-shaped protective strip 8. High-leg bolts 9 are installed on the inner side of these holes 10. Nuts 3 are threadedly connected to the right side of the outer wall of the high-leg bolts 9 to facilitate the fastening of the connecting parts. In order to enhance the stability of the structure, anti-crack mechanism 2 is provided on the outer wall of column water pipe 16 and column water pipe 17 to prevent cracking or damage during use.

[0033] Please see the appendix Figure 2 - Appendix Figure 4 Arc-shaped protective plates 203 are fixedly connected to the outer walls of column water pipe 16 and column water pipe 27. Arc-shaped grooves 206 are opened on the outer side of the outer wall of the arc-shaped protective plates 203. Spring steel 202 is engaged on the inner side of the arc-shaped grooves 206. Locking holes 205 are opened on the bottom of the outer wall of the spring steel 202. Hollow column 204 is fixedly connected to one end of the spring steel 202. A knob 201 is threaded on the inner side of the hollow column 204. The outer wall of the knob 201 fits against the inner side of the locking hole 205. The multiple locking holes 205 adopt an elongated design.

[0034] Specifically, these arc-shaped protective plates 203 are provided with arc-shaped grooves 206 to achieve their specific functions. Spring steel 202 is engaged on the inner side of these arc-shaped grooves 206 to provide the necessary elasticity and support, enhancing the stability and reliability of the structure. In addition, this can effectively transmit force and maintain the stability of the overall structure. For user convenience, the user can adjust the state of the device by rotating the knob 201. The outer wall of the knob 201 fits against the inner side of the locking port 205, ensuring the precise position of the knob 201 and the ease of operation. To adapt to different needs, a greater adjustment range and flexibility are provided. Through this design, the entire device is not only structurally stable but also easy to operate, meeting the needs of various practical applications.

[0035] Please see the appendix Figure 3 - Appendix Figure 5Both column water pipe 16 and column water pipe 17 have a circular strip 7 fixedly connected to the outer side of their outer walls. The multiple circular strips 7 are designed symmetrically. Both flange 1 and flange 2 are fixedly connected to the top of their outer walls. The multiple C-shaped protective strips 8 are set at the same horizontal height. The middle of the outer wall of the connecting pipe 11 has multiple anti-slip grooves 4. The multiple anti-slip grooves 4 are designed in a diamond shape. Both column water pipe 16 and column water pipe 17 have a circular strip 6 fixedly connected to the outer side of their outer walls. The multiple circular strips 6 are designed symmetrically.

[0036] Specifically, the design of these circular strips 7 is carefully considered to ensure the stability and safety of the structure. Multiple circular strips 7 employ a symmetrical design, meaning they are structurally uniformly distributed, ensuring overall balance and even stress distribution. This also enhances reliability and durability in practical applications, preventing accidental collisions or scratches during use. The uniform distribution of the protective strips throughout the device provides consistent protection at the corresponding height, contributing to improved overall safety. The symmetrical design of the multiple circular strips 6 not only improves the overall structure but also ensures stability and reliability in practical applications. This symmetrical design effectively disperses external forces, reduces localized stress concentration, and extends the device's service life.

[0037] Working principle: When water pipes need to be connected, firstly, the waterproof strip 13 is evenly wrapped around the outer wall of the external thread 12. Then, the first column water pipe 16 and the second column water pipe 17 are fixed to the first flange 1 and the second flange 5 respectively. At this time, the first flange 1 and the second flange 5 are twisted to the inside of the internal thread 15 to connect the water pipes. Then, the sealing rings 14 on both sides are used to seal the connection. Finally, the corresponding high bolt 9 is picked up and passed through the inside of the hole 10. Then, the nut 3 is used to twist it to limit the high bolt 9 and ensure that the first flange 1 and the second flange 5 cannot move. Therefore, the design of the connector makes the installation and disassembly of water pipes more convenient and quick, reduces maintenance costs, and meets the daily use needs of operators.

[0038] Afterwards, flange 1 and flange 2 are installed on the outer walls of column water pipe 16 and column water pipe 27. Then, spring steel 202 is picked up and fitted along the inner side of arc groove 206. Then, by turning knob 201 on hollow column 204 and rotating it along the inner side of locking port 205, spring steel 202 is slowly tightened, which enhances the surface strength of column water pipe 16 and column water pipe 27. This strengthens the surface strength of the water pipe, prevents cracking, and improves the service life of the water pipe.

[0039] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
