DETAILED DESCRIPTION
[0020] The embodiments of the present invention will be described below with reference to the accompanying drawings.
[0021] Embodiment: A pipe connection device for building water supply and drainage, such as Figure 1-Figure 3As shown, it includes a connecting pipe 1, a pipe head 2, a fixed plate 201, a baffle 3, a first guide rod 302, a first spring 303, a clamping plate 401 and a connecting mechanism. The connecting pipe 1 is provided with a pipe head 2 at one end, and a connecting mechanism is provided on the connecting pipe 1. The connecting pipe 1 is connected to the clamping plate 401 through the connecting mechanism. The connecting pipe 1 is fixedly connected to the fixing plate 201, and the clamping plate 401 is plugged with the fixing plate 201. A plurality of first guide rods 302 are fixedly connected to the connecting pipe 1, and a baffle 3 is slidably connected to the first guide rod 302. The plurality of baffles 3 are enclosed to clamp the pipe head 2 A first spring 303 is wound around the first guide rod 302, and both ends of the first spring 303 are respectively connected to the baffle 3 and the end of the first guide rod 302 away from the connecting tube 1. Here, the connecting mechanism includes a connecting plate 4 and a second guide rod 402. The second guide rod 402 is fixedly connected to the connecting tube 1, and the second guide rod 402 is slidably connected to the connecting plate 4. The end of the connecting plate 4 away from the second guide rod 402 is slidably connected to the clamping plate 401; the baffle 3 is designed as an arc structure, and the baffles 3 are circumferentially distributed on the connecting tube 1, and multiple baffles 3 are surrounded to form a closed annular design structure.
[0022] like Figure 3 As shown, a second spring 403 is wound around the second guide rod 402, and both ends of the second spring 403 are respectively connected to the second guide rod 402 and the connecting plate 4. Here, the second spring 403 is compressed to a certain extent under normal conditions, so that it can exert a force on the connecting plate 4 through its own resilience, and then the connecting plate 4 exerts a force on the clamping plate 401, so that the clamping plate 401 abuts against the fixed plate 201 after being subjected to the force, thereby ensuring the stability of the connection between the clamping plate 401 and the fixed plate 201.
[0023] like Figure 2 As shown, a sealing block 301 is fixedly connected to one side of the baffle plate 3. Here, the sealing block 301 is made of rubber. The design of the sealing block 301 can clamp the pipe head 2 on the baffle plate 3 and seal the gap between the baffle plate 3 and the pipe head 2 by its own deformation, thereby further improving the sealing performance of the device.
[0024] like Figure 2 and Figure 4 As shown, a first valve plate 5 is fixedly connected to the inside of the connecting pipe 1, and the first valve plate 5 is rotatably connected to the second valve plate 502. A motor 501 is installed on the first valve plate 5, and the output shaft of the motor 501 passes through the first valve plate 5 and is connected to the second valve plate 502. Here, the motor 501 is started, and the motor 501 drives the output shaft to rotate. The output shaft of the motor 501 drives the connected second valve plate 502 to rotate until the second valve plate 502 coincides with the first valve plate 5, and the second valve plate 502 no longer blocks the connecting pipe 1, so that the water flow can pass through the connecting pipe 1, thereby achieving the effect of controlling the flow of water.
[0025] The device is used for connecting pipes 1. When in use, the pipe head 2 is matched with the connecting pipe 1, and then the clamping plate 401 is lifted upward, and then one end of the pipe head 2 is inserted into the connecting pipe 1. The pipe head 2 moves to squeeze the baffle 3, so that the baffle 3 moves away from the center of the connecting pipe 1. The baffle 3 no longer blocks the moving path of the pipe head 2. At this time, the first spring 303 is compressed. When the fixed plate 201 on the pipe head 2 corresponds to the clamping plate 401, the clamping plate 401 is released, and the clamping plate 401 is plugged and matched with the fixed plate 201. At the same time, the first spring 303 is restored by its own resilience, so that the first spring 303 applies a thrust to the baffle 3 to push the baffle 3 into the connecting pipe 1. The baffles 3 on the connecting pipe 1 move to the center, causing the baffles 3 on the connecting pipe 1 to approach each other, thereby clamping the pipe head 2, thereby completing the fixing of the pipe head 2. When the baffles 3 clamp the pipe head 2, the baffles 3 are surrounded to form a closed ring and maintain contact with the pipe head 2, thereby blocking the gap between the pipe head 2 and the connecting pipe 1 to achieve a sealing effect. Subsequently, the motor 501 is started, and the motor 501 drives the output shaft to rotate. The output shaft of the motor 501 drives the connected second valve plate 502 to rotate until the second valve plate 502 coincides with the first valve plate 5, and the second valve plate 502 no longer blocks the connecting pipe 1, so that the water flow can pass through the connecting pipe 1 to achieve a circulation effect, and the work is completed.
