Technical Field

[0001] This utility model relates to the field of building construction, and in particular to a water supply and drainage pipe connection device for the renovation of old residential areas. Background Technology

[0002] Water pipes in older residential areas often leak due to aging and other issues, so it is necessary to renovate the water pipes in these areas. This process involves using connecting devices for water inlets and outlets, which are mainly used to connect new and old pipes or pipes of different materials, thereby achieving the connection and secure sealing of the pipe network system.

[0003] Traditional water pipes are often connected using rubber sealing joints, which are then fixed at both ends with clamps. However, gaps can still appear at the connection between the rubber sealing joint and the water pipe, affecting the sealing performance and causing leaks at the pipe connection. This issue needs to be addressed. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a water pipe connection device for the renovation of old residential areas, which has the effect of improving the sealing of the connection position.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a water supply and drainage pipe connection device for the renovation of old residential areas, comprising: Rubber sleeves, with both ends used to be fitted onto the outer walls of the water inlet and outlet pipes respectively; Clamps are provided at both ends of the rubber sleeve; A sealing tube, with a U-shaped cross-section, is provided at both ends of the rubber sleeve. A sealing groove is provided on the inner wall of the lower end of the sealing tube, and a rubber sheet is embedded in the sealing groove. A sealing ring is threaded to the sealing tube and is used to compress the air inside the sealing tube, causing the rubber sheet to bulge and press against the outer wall of the water pipe.

[0006] In a preferred embodiment, the present invention can be further configured such that a rubber ring is vertically slidably connected inside the sealing tube.

[0007] In a preferred embodiment, the present invention can be further configured such that the inner wall of the sealing tube is disposed above the sealing groove and is a retaining ring that blocks the sealing ring.

[0008] In a preferred embodiment, the present invention can be further configured such that a handwheel is provided at the end of the sealing ring.

[0009] In a preferred embodiment, the present invention can be further configured such that: both sides of the handwheel are provided with a fixing plate extending vertically downward, and the fixing plate is connected horizontally with a locking pin that presses against the outer wall of the sealing tube.

[0010] In a preferred embodiment, the present invention can be further configured such that: a rubber pad is provided on the outer wall of the fixing plate, and the end cap of the locking pin presses against the rubber pad.

[0011] In a preferred embodiment, the present invention can be further configured such that the inner wall of the sealing tube is flush with the inner wall of the rubber sleeve.

[0012] In a preferred embodiment, the present invention can be further configured such that the outer wall of the sealing tube extends to the outside of the rubber sleeve and is used for clamping with the clamp.

[0013] In summary, this utility model has the following beneficial effects: 1. By setting sealing tubes at both ends of the rubber sleeve and setting inflatable rubber sheets inside the sealing tubes, the sealing tubes can form an airbag structure and press against the outer wall of the water inlet and outlet pipes, thereby achieving a double seal between the rubber sleeve and the water inlet and outlet pipes, improving the sealing performance of the connection and preventing water leakage. 2. By setting a secondary locking mechanism on the sealing ring, the sealing ring is prevented from rotating and loosening, thereby ensuring the sealing of the connection position.

[0016] The present invention will be further described in detail below with reference to the accompanying drawings.

[0017] like Figure 1 , Figure 2 As shown, a water pipe connection device for the renovation of old residential areas includes a rubber sleeve 1, a clamp 2, a sealing pipe 3, and a sealing ring 4.

[0018] like Figure 2 , Figure 3As shown, the two ends of the rubber sleeve 1 are used to be fitted onto the outer walls of the water inlet and outlet pipes respectively, and the clamp 2 is set at both ends of the rubber sleeve 1 to tighten the rubber sleeve 1 onto the water inlet and outlet pipes.

[0019] like Figure 2 , Figure 3 As shown, the sealing tube 3 has a U-shaped cross-section and is located at both ends of the rubber sleeve 1. The inner wall of the sealing tube 3 is flush with the inner wall of the rubber sleeve 1, and the outer wall of the sealing tube 3 extends to the outside of the rubber sleeve 1 and is used for clamping by the clamp 2.

[0020] like Figure 2 , Figure 3 As shown, the sealing tube 3 is made of rigid plastic, and a sealing groove 31 is provided on the inner wall of the lower end of the sealing tube 3, and a rubber sheet 32 ​​is embedded in the sealing groove 31.

[0021] like Figure 2 , Figure 3 As shown, the sealing ring 4 is threadedly connected to the sealing tube 3 and is used to compress the air inside the sealing tube 3, causing the rubber sheet 32 ​​to bulge and press against the outer wall of the upper and lower water pipes. A rubber ring 5 is vertically slidably connected inside the sealing tube 3, and a retaining ring 6 is located above the sealing groove 31 and blocks the sealing ring 4 on the inner wall of the sealing tube 3.

[0022] like Figure 2 , Figure 3 As shown, a handwheel 7 is provided at the end of the sealing ring 4 for easy control of the rotation of the sealing ring 4. A fixing plate 8 extends vertically downwards on both sides of the handwheel 7, and a locking pin 9, which presses against the outer wall of the sealing tube 3, is horizontally threaded onto the fixing plate 8. A rubber pad 81 is provided on the outer wall of the fixing plate 8, and the end cap of the locking pin 9 presses against the rubber pad 81.

[0023] When it is necessary to connect the water supply and drainage pipes, first put the sealing ring 4 on the water supply and drainage pipes, then put the rubber ring 5 on the water supply and drainage pipes, and finally put both ends of the rubber sleeve 1 on the outer wall of the water supply and drainage pipes respectively, and make the sealing tube 3 wrap around the water supply and drainage pipes.

[0024] Then, the clamp 2 is fixed to both ends of the rubber sleeve 1, so that the clamp 2 tightens both ends of the rubber sleeve 1 onto the water inlet and outlet pipes, and the clamp 2 is snapped into the sealing pipe 3, thereby positioning the clamp 2 and realizing the quick installation and fixing of the rubber sleeve 1.

[0025] Then, insert the rubber ring 5 into the sealing tube 3 and control the handwheel 7 to rotate, so that the sealing ring 4 is screwed into the sealing tube 3. At this time, as the sealing ring 4 is continuously screwed in, it will press the rubber ring 5 to move vertically, and the rubber ring 5 will compress the air in the sealing tube 3.

[0026] Until the rubber ring 5 contacts the retaining ring 6 inside the sealing tube 3, the sealing ring 4 presses the rubber ring 5, compresses the air inside the sealing tube 3, and at the same time presses the rubber sheet 32 ​​to bulge and press against the outer wall of the water pipe, thus completing the secondary seal between the rubber sleeve 1 and the water pipe.

[0027] Finally, tighten the locking pin 9 so that it presses against the outer wall of the sealing tube 3. At the same time, the end cap of the locking pin 9 is pressed and embedded in the rubber pad 81 to prevent the locking pin 9 from loosening. This also locks and fixes the sealing ring 4, preventing gas leakage from the sealing tube 3 and ensuring that the rubber sheet 32 ​​is tightly clamped to the outer wall of the water pipe.

[0028] Therefore, by setting sealing tubes 3 at both ends of the rubber sleeve 1, and installing inflatable rubber sheets 32 inside the sealing tubes 3, the sealing tubes 3 can form an airbag structure and press against the outer wall of the water pipes, achieving a double seal between the rubber sleeve 1 and the water pipes, improving the sealing performance at the connection point and preventing leakage. This also serves as an emergency sealing method, further helping to prevent leakage at pipe connections.

[0029] The specific embodiments are merely explanations of this utility model and are not intended to limit it. After reading this specification, those skilled in the art can make modifications to these embodiments without contributing any inventive step, but such modifications are protected by patent law as long as they fall within the scope of the claims of this utility model.
