Description

Technical Field

[0001] This utility model belongs to the field of drainage pipe installation technology, specifically relating to a water supply and drainage pipe connector. Background Technology

[0002] In modern urban construction and various industrial and civil facilities, water supply and drainage systems play a vital role, acting as the "blood vessels" of the city to ensure the rational transportation and discharge of water resources. As a key component of the water supply and drainage system, the performance of water supply and drainage pipe connectors directly affects the overall system's operational efficiency, reliability, and service life.

[0003] When connecting pipes for drainage or water supply, pipe connectors are required. Existing connectors connect pipes by inserting them into the connector, with the pipe abutting against the inner wall of the connector. However, they can only connect two pipes of the same size. When the pipes at both ends of the connector are of different sizes or cannot abut against the inner wall of the connector, the pipes cannot be connected. To solve this problem, we propose a water supply and drainage pipe connector. Utility Model Content

[0004] The purpose of this utility model is to provide a water supply and drainage pipe connector to solve the problems mentioned in the background art.

[0005] To achieve the above-mentioned technical objectives, the technical solution adopted by this utility model is as follows: A water supply and drainage pipe connector includes a fixed pipe, with connecting sleeves fixed at both ends of the fixed pipe. At least one pipe gasket is provided inside each of the two connecting sleeves, and the pipe gasket is attached to the inner wall of the connecting sleeve. The connecting sleeve sidewall is provided with several stabilizing components. The stabilizing components include a sliding groove opened in the inner wall of the connecting sleeve, an arc-shaped plate slidingly disposed in the sliding groove, a threaded through hole opened in the middle of the sliding groove, a fixing bolt threadedly connected in the threaded through hole, and the end of the fixing bolt being rotatably connected to the arc-shaped plate.

[0006] The arc-shaped plate has an annular groove, and the fixing bolt fixes a rotating block that is rotatably installed in the annular groove.

[0007] The inner side of the tube pad is provided with anti-slip texture.

[0008] The end of the connecting sleeve is provided with a fixing component; The fixing component includes two sets of symmetrically arranged semi-circular clamps. The bottom of the two semi-circular clamps is rotated at the end of the connecting sleeve via a rotating shaft. The upper end of each of the two semi-circular clamps is fixed with an ear piece. Each of the two ear pieces has a mounting hole. A bolt is installed in each of the two mounting holes, and a nut is installed on the bolt.

[0009] The fixed tube has a telescopic section in the middle.

[0010] The telescopic part of the fixed tube is made of plastic material.

[0011] An adjustment assembly is provided between the two connecting sleeves. The adjustment assembly includes a threaded sleeve fixed to one of the connecting sleeves, and a threaded rod threadedly connected to the threaded sleeve is rotatably mounted on the other sleeve. A knob is installed at the end of the threaded rod.

[0012] Multiple sets of telescopic rods are provided between the two connecting sleeves.

[0013] This invention allows for adjustments to the connection structure based on the size of water supply and drainage pipes by increasing or decreasing the number of pipe pads, thus meeting diverse pipe connection needs.

[0014] This utility model uses a rotating fixing bolt to push the arc-shaped plate to slide, so that the multi-layer pipe gasket tightly contacts and clamps the pipe, thereby enhancing the connection stability.

[0015] This utility model adopts a semi-circular clamp structure, and uses bolts and nuts to fix the lugs, further enhancing the connection between the pipe and the connecting sleeve.

[0016] This invention utilizes a threaded sleeve and a threaded rod in conjunction with a knob for adjustment, and a telescopic rod for assistance, to flexibly adjust the distance between the two connecting sleeves and adapt to pipe connections of different lengths.

Detailed Implementation

[0021] To enable those skilled in the art to better understand this utility model, the technical solution of this utility model will be further described below in conjunction with the accompanying drawings and embodiments.

[0022] Example 1: like Figure 1-3 As shown, a water supply and drainage pipe connector of the present invention includes a fixed pipe 1, which serves as the main structure of the connector and is used to connect two water supply and drainage pipes. Both ends of the fixed pipe 1 are fixed with connecting sleeves 11. Each of the two connecting sleeves 11 is provided with at least one pipe pad 12, which is attached to the inner wall of the connecting sleeve 11. The connecting sleeve 11 has several stabilizing components on its side wall. The stabilizing components include a groove 13 on the inner wall of the connecting sleeve 11, an arc plate 14 slidingly disposed in the groove 13, a threaded through hole in the middle of the groove 13, a fixing bolt 15 threadedly connected in the threaded through hole, and the end of the fixing bolt 15 rotatably connected to the arc plate 14.

[0023] The arc plate 14 has an annular groove 141, and the fixing bolt 15 fixes a rotating block 151 that is rotatably installed in the annular groove 141; the rotating block 151 rotates in the annular groove 141 to achieve a rotatable connection between the end of the fixing bolt 15 and the arc plate 14.

[0024] The inner side of the pipe gasket 12 is provided with anti-slip texture. Each of the two connecting sleeves 11 has at least one layer of pipe gasket 12 inside. The pipe gasket 12 is attached to the inner wall of the connecting sleeve 11. The anti-slip texture on the inner side of the pipe gasket 12 can increase the friction with the outer wall of the pipe, prevent the pipe from sliding, and at the same time play a certain sealing role. The number of pipe gaskets 12 can be adjusted according to the size of the water supply and drainage pipes to be connected, so as to accommodate pipe connections of different sizes. By rotating the fixing bolts 15, the arc plate 14 can be pushed to slide in the groove 13, so that the multi-layer pipe gaskets 12 are in tight contact, enhancing the sealing performance, and thereby clamping the pipe inserted into the connecting sleeve 11, enhancing the stability of the connection.

[0025] How to use: Depending on the size of the pipe, at least one pipe gasket 12 is fitted and installed on the inner wall of the connecting sleeve 11, ensuring that the anti-slip texture on the inner side of the pipe gasket 12 faces the pipe insertion direction.

[0026] Insert the water supply and drainage pipes that need to be connected into the connecting sleeves 11 at both ends of the fixed pipe 1, so that the pipes are in close contact with the pipe gasket 12.

[0027] Rotate the fixing bolt 15 to push the arc plate 14 to slide towards the pipe until the arc plate 14 clamps the pipe, ensuring that the pipe is firmly connected to the connecting sleeve 11.

[0028] Example 2: like Figure 4-5 As shown, a fixing component is provided at the end of the connecting sleeve 11; The fixing component includes two sets of symmetrically arranged semi-circular clamps 2. The bottom of the two semi-circular clamps 2 is rotated at the end of the connecting sleeve 11 via a rotating shaft. The upper end of each of the two semi-circular clamps 2 is fixed with a lug 21. Each lug 21 has a mounting hole. A bolt 23 is installed in each of the two mounting holes. A nut 24 is installed in each bolt 23.

[0029] The two semi-circular clamps 2 are closed to wrap around the pipe, and the lugs 21 are fixed by bolts 23 and nuts 24, which further enhances the connection between the pipe and the connecting sleeve 11.

[0030] How to use: Insert the water supply and drainage pipe into the connecting sleeve 11, close the two semi-circular clamps 2, and align the mounting holes on the ear pieces 21.

[0031] Pass the bolt 23 through the two mounting holes and screw on the nut 24. Gradually tighten the nut 24 so that the semi-circular clamp 2 tightly wraps around the pipe, enhancing the connection stability.

[0032] Example 3: like Figure 6 As shown, a telescopic section 03 is provided in the middle of the fixed pipe 1. The telescopic section 03 allows the fixed pipe 1 to expand and contract within a certain range to accommodate the slight deformation of the pipe caused by factors such as temperature changes and pressure fluctuations, and to avoid damage to the connector or pipe due to stress concentration.

[0033] The telescopic part 03 of the fixed tube 1 is made of plastic material.

[0034] An adjustment assembly is provided between the two connecting sleeves 11. The adjustment assembly includes a threaded sleeve 3 fixed to one of the connecting sleeves 11, and a threaded rod 31 threadedly connected to the threaded sleeve 3 is rotatably mounted on the other sleeve 11. A knob 32 is installed at the end of the threaded rod 31.

[0035] Multiple sets of telescopic rods 33 are provided between the two connecting sleeves 11.

[0036] By rotating the knob 32, the threaded rod 31 can be rotated within the threaded sleeve 3, thereby adjusting the distance between the two connecting sleeves 11 to accommodate pipe connection requirements of different lengths. Furthermore, multiple sets of telescopic rods 33 are provided between the two connecting sleeves 11. These telescopic rods 33 provide auxiliary support and stability, ensuring the overall stability of the connector during adjustment.

[0037] How to use: Depending on the required pipe length, rotate knob 32 to rotate threaded rod 31 within threaded sleeve 3, adjusting the distance between the two connecting sleeves 11 until the appropriate length is achieved. During adjustment, telescopic rod 33 extends and retracts accordingly, ensuring the overall stability of the connector.

[0038] Following the method of Embodiment 1 or Embodiment 2, the water supply and drainage pipes are respectively inserted into the two connecting sleeves 11, and the pipes are securely fixed by the stabilizing and fixing components, thus completing the connection of the water supply and drainage pipes. The above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit this utility model. Any person skilled in the art can modify or change the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or changes made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
