[0002] In the field of building engineering, water supply and drainage pipeline systems are important infrastructure of buildings, and the reliability of their connection structure directly affects the operating efficiency and service life of the entire system.

[0003] Traditional water supply and drainage pipe connections mainly use threaded connections and flange connections. While flange connections offer good sealing, they require multiple bolts, and tightening each bolt takes considerable time, resulting in low installation efficiency. Threaded connections, on the other hand, can improve installation efficiency, but they require high precision in thread machining. Insufficient precision can lead to inadequate sealing and leakage. Utility Model Content

[0004] The purpose of this utility model is to provide a building water supply and drainage pipe connection device that can improve installation efficiency to a certain extent, while also improving the sealing performance of the water supply and drainage pipe connection.

[0005] The aforementioned building water supply and drainage pipe connection device includes a connecting pipe, with connecting pipes for connecting water supply and drainage pipes connected to both ends of the connecting pipe.

A compression ring is provided in the connecting groove to guide the locking end of the locking tube to tighten inward.

[0006] Furthermore, a rotating ring is fitted onto the locking tube to facilitate its rotation.

[0007] Furthermore, an anti-slip pad to increase friction is provided on the inner wall of the locking end of the locking tube.

[0008] Furthermore, the cross-section of the extrusion ring is triangular.

[0009] Furthermore, a sealing ring is provided at the bottom of the docking groove.

[0010] Furthermore, the rotating ring has two symmetrically distributed first pin grooves, and the outer wall of the connecting pipe has several second pin grooves distributed along its circumference. Any two second pin grooves and two first pin grooves are provided with the same pin block.

[0011] Furthermore, the locking end of the locking tube has a chamfer that engages with the compression ring to tighten inward.

[0019] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, but this is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention. Example

[0020] This embodiment describes a building water supply and drainage pipe connection device, such as... Figures 1 to 4 As shown, the device includes a connecting pipe 1, with connecting pipes 2 for connecting water supply and drainage pipes at both ends. The connecting pipes 2 communicate internally with the connecting pipe 1. Each end of the connecting pipe 2 has a connecting groove for connecting the water supply and drainage pipes, located between the inner and outer walls of the connecting pipe 2. The connecting groove is annular and lies between the inner and outer walls of the connecting pipe 2. When the water supply and drainage pipe connects to the connecting pipe 2, its end is inserted into the connecting groove, and the inner wall of the water supply and drainage pipe fits against the inner wall of the connecting groove. This allows a sealing ring, made of rubber, to be fitted inside the connecting groove and along its inner wall, thus forming a sealing barrier between the connecting pipe 2 and the water supply and drainage pipe.

[0021] The outer wall of the docking groove is provided with an internal thread, and a locking tube 5 for locking the water supply and drainage pipe is independently installed in the docking groove. The outer wall of the locking tube 5 is provided with an external thread that is threaded to the internal thread. The locking end of the locking tube 5 is provided with several movable grooves that are evenly distributed along its circumference. A compression ring 6 is provided in the docking groove to guide the locking end of the locking tube 5 to tighten inward.

[0022] The wall thickness between the inner and outer walls of the water supply and drainage pipe is less than the distance between the inner and outer walls of the docking groove. In other words, when the water supply and drainage pipe is inserted into the docking groove, there is a gap at one end between the outer wall of the water supply and drainage pipe and the inner wall of the docking groove. The locking tube 5 is fitted onto the water supply and drainage pipe and is located in the docking groove, so it exists at this gap. The external thread on the locking tube 5 is threadedly engaged with the internal thread on the inner wall of the docking groove, so that by rotating the locking tube 5, the locking tube 5 can move in the docking groove.

[0023] A movable groove is formed at the locking end of the locking tube 5 and communicates with the inner and outer walls of the locking tube 5. When the locking end of the locking tube 5 contacts the compression ring 6, as the inner diameter of the compression ring 6 gradually decreases, the inner diameter of the compression ring 6 forces the locking end of the locking tube 5 to tighten inward and clamp onto the water supply and drainage pipe, forming a connection between the connecting pipe 2 and the water supply and drainage pipe. The inner wall of the connecting groove in the water supply and drainage pipe serves as support to prevent the water supply and drainage pipe from deforming due to the clamping of the locking tube 5, thus ensuring a secure connection.

[0024] like Figure 2 As shown, a rotating ring 4 is fitted onto the locking tube 5 to facilitate its rotation. The outer wall of the rotating ring 4 has anti-slip textures to increase friction during rotation. In use, the rotating ring 4 allows for better rotation of the locking tube 5. The locking tube 5 is made of elastic material and possesses good elastic deformation capability.

[0025] like Figure 3 As shown, an anti-slip pad 8, made of silicone, is provided on the inner wall of the locking end of the locking tube 5 to increase friction. When the locking end of the locking tube 5 is clamped onto the water supply and drainage pipe, it can effectively increase the friction between the two, making the connection between the tube and the water supply and drainage pipe more stable, and improving the sealing performance.

[0026] The compression ring 6 has a triangular cross-section. The inner diameter of the compression ring 6 is equivalent to the hypotenuse of the triangle, and its gradually decreasing inner diameter guides the tightening end of the locking tube 5 to tighten inward. The compression ring 6 is fixed at the corner between the bottom of the mating groove and the outer wall.

[0027] like Figure 3 As shown, the locking end of the locking tube 5 has a chamfer that cooperates with the compression ring 6 to tighten inward. This chamfer cooperates with the inner ring of the compression ring 6 to guide the locking tube 5 to tighten inward.

[0028] like Figure 1 As shown, a sealing ring 7 is provided at the bottom of the docking groove; after the water supply and drainage pipe is inserted into the docking groove, its end rests against the sealing ring 7 to improve the sealing performance and prevent drainage leakage. A rubber ring is provided on the inner wall of the locking pipe 5 to fit against the outer wall of the water supply and drainage pipe, which can further improve the sealing performance.

[0029] like Figure 2 and Figure 3 As shown, the rotating ring 4 has two symmetrically distributed first pin grooves, and the outer wall of the connecting pipe 2 has several second pin grooves distributed circumferentially. The same pin block 3 is installed in any two second pin grooves and two first pin grooves. After the locking pipe 5 is locked to the water supply and drainage pipe, the pin block 3 is locked into the first and second pin grooves to restrict the rotation of the rotating ring 4 and prevent slight rotation of the locking pipe 5 due to external interference. After the rotating ring 4 is tightened, the first pin groove is aligned with the second pin groove closest to the locking direction, and then the pin block 3 is driven into the first and second pin grooves.

[0030] like Figure 4 As shown, in actual use, the two water supply and drainage pipes are inserted into the mating grooves of the left and right connecting pipes 2 respectively. Then, the locking pipe 5 is rotated and, with the help of the thread, it is pushed into the mating groove until its locking end engages with the compression ring 6, thus locking the water supply and drainage pipes and completing the connection of the water supply and drainage pipes. The operation is simple and convenient, which can improve the installation efficiency to a certain extent. In addition, the inner and outer walls of the mating groove contact the water supply and drainage pipes, and the sealing performance is improved by a composite seal to prevent drainage leakage.

[0031] This product does not require modification of existing water supply and drainage pipes on the market. It is suitable for various water supply and drainage pipes of matching size. During production, it is only necessary to produce various models that match the various water supply and drainage pipe models on the market to improve the adaptability of the product.
