Description

Technical Field

[0001] This utility model relates to the field of building construction technology, and more specifically to a quick connection device for building water supply and drainage pipes. Background Technology

[0002] Building water supply and drainage pipe connection devices are key components used to connect water supply and drainage pipes, ensure the stable operation of the pipe system and the smooth transmission of fluids. Their functions include realizing fixed connections between pipes, sealing and preventing leaks, changing the direction or diameter of pipes, and splitting or merging fluids.

[0003] In existing technologies, traditional water supply and drainage pipe connection methods such as threaded connections, welding, and flange connections generally suffer from problems such as low installation efficiency, complex operation, and high requirements for pipe materials (e.g., welding is only applicable to metal pipes). For example, threaded connections require pre-processing of threads, which is time-consuming and labor-intensive; welding operations pose safety hazards and are difficult to disassemble; flange connections require more accessories and have precise requirements for the installation space between the two pipes. In addition, traditional connection methods are prone to pipe deformation due to compression when dealing with plastic pipes (e.g., through clamp-type clamp sealing), affecting sealing performance and service life. Utility Model Content

[0004] In order to overcome the above-mentioned defects of the prior art, the present invention provides a quick connection device for building water supply and drainage pipes to solve the problems existing in the background art.

[0005] The utility model provides the following technical solution: a quick connection device for building water supply and drainage pipes, including pipe one, pipe two, and a sleeve fitted onto the outer surfaces of pipe one and pipe two. A fixing ring is fixedly connected to the center of the inner wall of the sleeve, and an inner tube is fixedly connected to the inner wall of the fixing ring. Annular grooves are provided at both ends of the inner wall of the sleeve. A silicone ring is fixedly connected inside the annular groove. A sliding rod is laterally slidably connected inside the annular groove. A pressure ring is fixedly connected to the end face of the sliding rod near the silicone ring. A drive assembly is installed at the input end of the sliding rod.

[0006] Furthermore, the drive assembly includes a nut that is threadedly rotatably connected to the outer surface of the sleeve, a sliding groove is provided inside the sleeve, a limit bar is equidistantly and laterally fixed inside the sliding groove, a sliding plate is slidably connected to the outer surface of the limit bar, a positioning post is equidistantly fixed to the outer surface of the sliding plate, a rotating groove is provided on the inner wall of the nut, and the end face of the positioning post away from the limit bar extends into the rotating groove.

[0007] Furthermore, the outer diameter of the inner tube is equal to the inner diameter of pipe one and pipe two, the outer surface of the inner tube is attached to the outer surface of pipe one and pipe two, and both ends of the inner wall of the inner tube are arc-shaped.

[0008] Furthermore, both the outer surface and the inner wall of the silicone ring are arc-shaped, and the inner wall of the silicone ring abuts against the outer surfaces of pipe one and pipe two.

[0009] Furthermore, the outer surface of the sleeve is provided with threads that match the inner walls of pipe one and pipe two, and a steel ball is installed inside the sliding rod near the sliding plate. The steel ball extends to the outside of the sliding rod and rolls onto the surface of the sliding plate.

[0010] Furthermore, the sliding plate is annular, and the sliding plate is laterally slidably connected to the inside of the sliding groove by a limiting rod.

[0011] Furthermore, the end of the positioning post away from the sliding plate extends to the surface of the sleeve, the positioning post is slidably connected to the inside of the sleeve, and ball bearings are equidistantly installed at one end of the positioning post near the rotating groove. The surface of the ball bearings extends to the outer surface of the positioning post and is tumbledly connected to the inside of the rotating groove, which is annular.

[0012] The technical effects and advantages of this utility model are as follows:

[0013] 1. This utility model achieves rapid positioning and initial fixation of the pipeline through the cooperation of the inner tube and the sleeve. The arc-shaped port design of the inner tube reduces the resistance of the internal water flow. The linkage sealing structure of the silicone ring and the pressure ring achieves uniform application of sealing pressure through the mechanical transmission of the drive component. This not only ensures the high sealing performance of the connection parts, but also avoids the damage to the plastic pipe caused by the traditional extrusion method, significantly improving the applicability and reliability of the device.

[0014] 2. In this utility model, the drive component adopts a threaded transmission design of nut and positioning column. The pressure ring can be driven synchronously by rotating the nut. The operation process is simple and quick, which greatly shortens the construction time of pipeline connection. The guiding structure of sliding plate and limit bar ensures the stability of pressure ring movement.

[0020] The present invention will be further described below with reference to specific embodiments. However, those skilled in the art should understand that the detailed description given here with reference to the accompanying drawings is for better explanation. The structure of the present invention may exceed the limited embodiments described herein. Some equivalent alternatives or common means will not be described in detail here, but they still fall within the protection scope of this application.

[0021] Figures 1-4 This is the preferred embodiment of the present invention, which is described below in conjunction with the appendix. Figures 1-4 The present invention will be further described below.

[0022] A quick connection device for building water supply and drainage pipes includes a pipe 1, a pipe 2, and a sleeve 3 fitted onto the outer surfaces of the pipe 1 and the pipe 2. A fixing ring 4 is fixedly connected to the center of the inner wall of the sleeve 3. An inner tube 5 is fixedly connected to the inner wall of the fixing ring 4. Annular grooves 6 are provided at both ends of the inner wall of the sleeve 3. A silicone ring 7 is fixedly connected inside the annular groove 6. A sliding rod 9 is laterally slidably connected inside the annular groove 6. A pressure ring 8 is fixedly connected to the end face of the sliding rod 9 near the silicone ring 7. A drive assembly 10 is installed at the input end of the sliding rod 9.

[0023] The drive assembly 10 includes a nut 101 that is threadedly rotatably connected to the outer surface of the sleeve 3. A sliding groove 102 is provided inside the sleeve 3. A limit bar 103 is equidistantly and laterally fixed inside the sliding groove 102. A sliding plate 104 is slidably connected to the outer surface of the limit bar 103. A positioning post 105 is equidistantly fixed to the outer surface of the sliding plate 104. A rotating groove 106 is provided on the inner wall of the nut 101. The end face of the positioning post 105 away from the limit bar 103 extends into the rotating groove 106.

[0024] In this embodiment, when the nut 101 is rotated, the sliding plate 104 slides laterally along the limiting rod 103 through the rolling engagement of the rotating groove 106 and the positioning column 105, thereby pushing the sliding rod 9 to move. The rolling connection of the steel ball and the ball reduces the transmission resistance, realizes the uniform application of sealing pressure, and is simple and quick to operate, shortening the construction time. The detachable structure of the device, such as the sliding connection between the positioning column 105 and the sleeve 3 and the threaded connection of the nut 101, facilitates maintenance and reuse, which is in line with the concept of green construction.

[0025] Specifically, the outer diameter of the inner tube 5 is equal to the inner diameter of pipe 1 and pipe 2. The outer surface of the inner tube 5 is attached to the outer surface of pipe 1 and pipe 2. Both ends of the inner wall of the inner tube 5 are arc-shaped.

[0026] In this implementation scheme, the inner tube 5 is fitted with the inner walls of pipe 1 and pipe 2. After being connected by the sleeve 3, the pipes can be quickly aligned and initially fixed, reducing the alignment time during installation. The arc design at both ends of the inner wall of the inner tube 5 optimizes the flow channel inside the pipe, reduces the resistance when water flows through the connection part, and improves the fluid transmission efficiency.

[0027] Specifically, the outer surface and inner wall of the silicone ring 7 are both arc-shaped, and the inner wall of the silicone ring 7 abuts against the outer surface of pipe 1 and pipe 2.

[0028] In this embodiment, the arc-shaped structure of the silicone ring 7 allows it to fit tightly against the outer surfaces of pipe 1 and pipe 2. After being squeezed by the pressure ring 8, it deforms to form a flexible sealing layer, avoiding the deformation and damage to plastic pipes caused by traditional rigid extrusion. It is suitable for pipes of various materials. In its initial state, the silicone ring 7 is against the outer surface of the pipe. During the sliding process of the sleeve 3, it can flexibly adapt to the changes in the distance between pipe 1 and pipe 2, improving the compatibility of the device.

[0029] Specifically, the outer surface of the sleeve 3 is provided with threads that match the inner walls of pipe 1 and pipe 2. A steel ball is installed inside the sliding rod 9 at one end near the sliding plate 104. The steel ball extends to the outside of the sliding rod 9 and rolls onto the surface of the sliding plate 104.

[0030] In this embodiment, the threads on the outer surface of the sleeve 3 are engaged with the threads on the inner walls of pipe 1 and pipe 2. The initial fixing of the sleeve 3 and the pipe can be achieved through threaded connection in the early stage of installation to prevent displacement. The sliding rod 9 and the sliding plate 104 are connected by rolling steel balls, which converts sliding friction into rolling friction, greatly reducing the resistance of the drive component 10 during transmission and making operation more labor-saving.

[0031] Specifically, the sliding plate 104 is annular and is laterally slidably connected to the inside of the sliding groove 102 by the limiting rod 103.

[0032] In this embodiment, the annular sliding plate 104 slides laterally in the sliding groove 102 via the limiting rod 103, ensuring that the sliding plate 104 remains horizontal when moving and avoiding tilting, thereby driving multiple sliding rods 9 to move synchronously, ensuring that the pressure ring 8 uniformly compresses the silicone ring 7 and improving the sealing reliability.

[0033] Specifically, the end of the positioning post 105 away from the sliding plate 104 extends to the surface of the sleeve 3. The positioning post 105 is slidably connected inside the sleeve 3. Ball bearings are equidistantly installed inside the positioning post 105 near the end of the rotating groove 106. The surface of the ball bearings extends to the outer surface of the positioning post 105 and is slidably connected inside the rotating groove 106. The rotating groove 106 is annular.

[0034] In this embodiment, when the nut 101 rotates, the rotational motion is converted into axial sliding of the positioning column 105 through the rolling contact between the rotating groove 106 and the ball at the end of the positioning column 105. The ball design reduces frictional resistance, making the nut 101 rotate more smoothly and can be operated with one hand, which greatly shortens the construction time. The structure of the sliding connection between the positioning column 105 and the sleeve 3 and the threaded connection between the nut 101 and the sleeve 3 allows the drive assembly 10 to be quickly disassembled, which is convenient for pipeline system maintenance or reuse and conforms to the concept of green construction.

[0035] The working principle and usage process of this utility model are as follows: In use, the sleeve 3 is fitted onto the outer surfaces of pipe 1 and pipe 2, and the outer surface of the inner tube 5 is attached to the inner walls of pipe 1 and pipe 2. Since pipe 1 and pipe 2 can slide within the space between the sleeve 3 and the inner tube 5, the spacing between pipe 1 and pipe 2 can be flexibly adjusted. After the surfaces of the silicone rings 7 on both sides inside the sleeve 3 are against the surfaces of pipe 1 and pipe 2, the nut 101 is rotated clockwise using a wrench. The nut 101 abuts against the positioning post 105 through the rotating groove 106, causing the positioning post 105 to slide closer to the sliding rod 9. The positioning post 105 is then moved by the sliding plate... 104 drives the sliding rod 9 and the pressure ring 8 to slide, and makes the surface of the pressure ring 8 tightly abut against the surface of the silicone ring 7, causing the silicone ring 7 to deform. The silicone ring 7 becomes thinner, and the outer diameter of the silicone ring 7 increases while the inner diameter decreases. That is, the inner wall of the silicone ring 7 is tightly attached to the outer surface of pipe 1 and pipe 2. Since the inner walls of pipe 1 and pipe 2 are abutted by the inner tube 5, pipe 1 and pipe 2 can be quickly assembled. When the silicone ring 7 squeezes the surface of pipe 1 and pipe 2, it will not cause compression deformation of pipe 1 and pipe 2. Therefore, it can be used for pipe 1 and pipe 2 made of plastic material. Moreover, the connection device is easy to disassemble and reassemble and can be reused.

[0036] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model in any other way. Any person skilled in the art may make changes or modifications to the disclosed technical content to create equivalent embodiments. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of this utility model without departing from its technical solution shall still fall within the protection scope of this utility model.
