Description

Technical Field

[0001] This utility model relates to the technical field of drainage pipe connection equipment, specifically a building water supply and drainage pipe connection device. Background Technology

[0002] Building water supply and drainage pipes are widely used in buildings, including domestic water systems and natural rainwater systems. Building water supply and drainage pipes are made of various materials, such as steel drainage pipes and plastic drainage pipes. During installation, it is sometimes necessary to make transitional connections between the two types of pipes to facilitate future replacement and maintenance. The connection between the two can be achieved through relevant connection devices.

[0003] According to a public notice (Announcement No.: CN221402239U), the aforementioned application includes a protective cover installed on the outside of the connecting pipe to reinforce and protect the connection of the drainage pipe. The protective cover also includes a foam sleeve and edge-filled foam sleeve inside, which, through the elasticity of a spring, contact the surface of the connecting pipe and the connection between the connecting pipe and the first and second connecting pipes, facilitating the absorption of vibrations generated by the drainage pipe. The lower protective cover also includes a bottom connecting plate to facilitate fixing the connecting device to the wall, further reducing vibrations of the drainage pipe and extending its service life.

[0004] However, in actual use, the above-mentioned equipment can only be used to connect drainage pipes whose dimensions match the dimensions of the first and second connecting pipes. Its application range is small and its flexibility is poor, making it unable to meet the actual needs of various building environments. In view of this, we propose a building water supply and drainage pipe connection device. Utility Model Content

This building water supply and drainage pipe connection device features a connection mechanism that, in conjunction with a rotary knob, drives a connecting rod and a rotating gear, causing a fixed toothed plate and connecting block to slide within the installation groove, enabling flexible adjustment of the connecting block's position. The linkage between the threaded rod and the threaded knob allows for precise control of the radial clamping force of the clamping plate on the pipe. The curved design of the clamping plate and the rubber pad increase the contact area and friction, forming a double seal when combined with the silicone panel inside the connector.

Its arc-shaped design and silicone pad provide continuous flexible compensation clamping force after the initial fixing force is applied to the clamping main plate, effectively absorbing minor displacements caused by pipe vibration or thermal expansion and contraction. A protective sleeve encloses the expansion assembly, isolating it from external impurities and preventing excessive spring deformation. This design not only enhances connection reliability under different operating conditions but also reduces vibration noise and mechanical wear, extending the device's service life.

[0024] like Figures 1-5As shown, this utility model provides a technical solution: a building water supply and drainage pipe connection device, including a connecting pipe 1, a connector 11 fixedly connected to the end of the connecting pipe 1, the end of the connector 11 near the connecting pipe 1 is an output port 12, the end away from the connecting pipe 1 is a receiving port 13, and a connecting mechanism 2 is provided at the end of the connector 11 away from the connecting pipe 1. The connecting mechanism 2 includes: an installation groove 21, a connecting block 22, a rotating knob 23, a connecting rod 24, a rotating gear 25, a fixed toothed plate 26, a threaded rod 27, a threaded knob 28, a clamping plate 29, and a fixing plate 210.

[0025] In one embodiment of this utility model, an installation groove 21 is formed at the end of the connector 11 away from the connecting pipe 1. A connecting block 22 is slidably connected to the inner wall of the installation groove 21. A fixing toothed plate 26 is fixedly connected to the inner side wall of the connecting block 22. A rotating gear 25 is meshed with the tooth ends of the fixing toothed plate 26. A connecting rod 24 is fixedly connected to the end of the rotating gear 25 away from the connecting block 22. A rotating knob 23 is fixedly connected to the end of the connecting rod 24 away from the fixing toothed plate 26. The operator can rotate the rotating knob 23 to make the connecting rod 24 drive the rotating gear 25 to rotate. Furthermore, the connecting block 22 fixedly connected to the fixed end of the fixing toothed plate 26 can be moved. A threaded groove is formed on the outer surface of the connecting block 22. A threaded rod 27 is threadedly connected to the inner surface of the threaded groove. A cover plate is fixedly connected to the end of the threaded rod 27 away from the connecting block 22. The threaded rod 27 is threaded on the outer surface. The connecting block 22 is connected to a threaded knob 28. A clamping plate 29 is fixedly connected to the end of the threaded rod 27 away from the cover plate. By rotating the threaded knob 28, the threaded rod 27 can be moved vertically, and the relative position of the clamping plate 29 can be adjusted. At the same time, the end of the threaded rod 27 away from the clamping plate 29 is fixedly connected to the cover plate, which can limit the threaded rod 27. A fixing plate 210 is fixedly connected to the side wall of the connecting block 22. There are multiple sets of fixing plates 210, which are fixedly connected between the side walls of every two adjacent sets of connecting blocks 22. The length of the mounting groove 21 matches the length of the fixing tooth plate 26, and the length of the connecting block 22 is greater than the length of the mounting groove 21. A circular groove matching the size of the connecting rod 24 is opened on the outer surface of the connecting part 11, which can provide stable support for the rotation of the connecting rod 24. The outer wall of the connecting rod 24 abuts against the inner wall of the circular groove.

[0026] In addition, an auxiliary mechanism 3 is provided inside the fixed plate 210. The auxiliary mechanism 3 includes a telescopic rod 31. A groove is opened in the inner wall of the fixed plate 210. The bottom end of the groove is fixedly connected to the fixed end of the telescopic rod 31. A telescopic spring 32 is sleeved on the outer surface of the telescopic rod 31. A clamping sub-plate 34 is fixedly connected to the side of the telescopic spring 32 away from the bottom end of the groove. A protective sleeve 33 is fixedly connected to one end of the clamping sub-plate 34 near the telescopic rod 31. The other end of the protective sleeve 33 is fixedly connected to the bottom surface of the groove. By setting up the auxiliary mechanism 3, the clamping sub-plate 34 can adaptively expand and contract radially along the pipeline through the elastic cooperation between the telescopic spring 32 and the telescopic rod 31. Its arc-shaped design and silicone pad provide continuous flexible compensation clamping force after the clamping plate 29 applies the initial fixing force, effectively absorbing the small displacement caused by pipeline vibration or thermal expansion and contraction. The protective sleeve 33 wraps the expansion component, isolating it from external impurities and preventing excessive deformation of the spring. This design not only enhances the connection reliability under different working conditions, but also reduces vibration noise and mechanical wear, and extends the service life of the device.

[0027] In this embodiment of the invention, the connector 11 is narrow near the connecting pipe 1 and wide away from the connecting pipe 1. A silicone panel is fixedly connected to the inner surface of the connector 11. The tapered interior of the connector 11 allows for the use of pipes of different diameters. The silicone panel effectively seals and waterproofs the connection. The clamping plate 29 is arc-shaped at the end away from the threaded rod 27, and a rubber pad is fixedly connected to the end of the clamping plate 29 away from the threaded rod 27. The arc-shaped clamping plate 29 better adapts to the outer wall of the connecting pipe, and the rubber pad enhances friction while protecting the outer wall of the pipe, providing a certain shock absorption effect. Two sets of connectors 11 are provided, and the two sets of connectors 11 are mirror-symmetrically distributed at the end of the connecting pipe 1. The arrangement of the two sets of connectors 11 allows for the connection of pipes of different diameters to both ends of the connecting pipe 1. The connector 11 is fixedly connected to one end of the connecting pipe 1, and the other end of the fixing bracket is fixedly connected to the outer surface of the connecting pipe 1. By setting the fixing bracket, the stable operation of the connection can be more stably guaranteed. The lower surface of the rotary knob 23 and the upper surface of the threaded knob 28 are both fixedly connected to the locking block 4. The setting of the locking block 4 allows the operator to lock the position after adjusting it to achieve a better fixing effect and prevent the connection from being unstable due to excessive water pressure or external vibration. The clamping sub-plate 34 is set in an arc shape, and a silicone pad is fixedly connected to the side of the clamping sub-plate 34 away from the fixing plate 210. The arc-shaped clamping sub-plate 34 can make the clamping sub-plate 34 fit the outer wall of the pipe more closely. The length of the telescopic rod 31 and the telescopic spring 32 is set to be greater than that of common standard connecting pipes to provide a better clamping effect.

[0028] In this invention, during use, at the receiving interfaces 13 of the connectors 11 symmetrically arranged at both ends of the connecting pipe 1, the operator first rotates the rotary knob 23, causing the connecting rod 24 and the rotating gear 25 to rotate. The rotating gear 25 meshes with the fixed toothed plate 26 fixed on the sliding connecting block 22, thereby driving the connecting block 22 to slide within the mounting groove 21 for initial position adjustment. Subsequently, rotating the threaded knob 28 pushes the threaded rod 27 and its end arc-shaped clamping plate 29 towards the pipe to be connected, performing rigid clamping and fixing. Simultaneously, the auxiliary mechanism 3 located inside the fixed plate 210 provides elastic support and auxiliary clamping force during the clamping process, enhancing the stability and sealing of the connection. The entire device combines coarse positioning through gear and rack adjustment with fine clamping through threaded top pressure, supplemented by elastic elements, to achieve rapid and reliable pipe connection.

[0029] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
