[0002] PVC drainage pipes are currently the most widely used drainage pipes. They have been unanimously praised by the engineering community for their light weight, corrosion resistance, high compressive strength, safety and convenience. PVC drainage pipes are widely used in residential buildings. In current high-rise and super-high-rise residential buildings, bathrooms, kitchens and other areas are generally PVC pipes that run through the upper and lower areas. Since there are many residences in the building and people are using the kitchen or bathroom all the time, PVC drainage pipes will continuously generate noise, especially at night. The noise generated when water is drained from high floors to low seriously affects people's rest and the tranquility of the room.

[0003] Therefore, Chinese Patent Publication No. CN219082484U proposes a PVC silent drainage pipe, which includes a first PVC pipe, a second PVC pipe, and a third PVC pipe. The first PVC pipe, the second PVC pipe, and the third PVC pipe are coaxially arranged with increasing diameters.

A first support member is provided in the vibration-damping layer, and a second support member is provided in the sound insulation layer. The PVC silent drainage pipe of the utility model has a simple structure, a reasonable design, and is easy to produce, achieving excellent quietness of the PVC drainage pipe.

[0004] However, when this type of PVC silent drainage pipe is in use, the pipe connections are generally fixed by bolts. When the pipes are disassembled and assembled, tools such as wrenches are needed to disassemble the pipes, which is time-consuming and troublesome, resulting in defects in the use of the device. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the present invention provides a PVC silent drainage pipe to solve the problems raised in the above background technology:

[0006] When this type of PVC silent drainage pipe is in use, the general pipe connection is fixed by bolts. When the pipe is disassembled and assembled, it is necessary to use tools such as wrenches to disassemble the pipes, which consumes a long time and is more troublesome.

[0007] In order to achieve the above objectives, the present invention is implemented through the following technical solutions:

[0008] A PVC silent drainage pipe comprises a pipe body, wherein the inner wall surface of the pipe body is provided with multiple groups of protrusions, one end of the pipe body is fixedly connected to a threaded sleeve, and the end of the threaded sleeve away from the pipe body is rotatably connected to a fixing ring, and two groups of fixing rings are provided, and the two groups of fixing rings are detachably connected by bolts, one end of the bolt is fixedly connected to a connecting plate, and the side of the connecting plate away from the bolt is fixedly connected to a fixing block, the interior of the fixing block is rotatably connected to a connecting shaft, one end of the connecting shaft passes through one side of the fixing block and is rotatably connected to the connecting plate, the interior of the fixing block is rotatably connected to a pawl, and the outer side of the connecting shaft is fixedly connected to a ratchet, and the ratchet is used in conjunction with the pawl.

[0009] Preferably, a fixing plate is fixedly connected to the interior of the fixing block, and a spring is provided between one side of the fixing plate and the pawl.

[0010] Preferably, one end of the connecting shaft away from the connecting plate passes through one side of the fixing block and is fixedly connected to a connecting rod.

[0015] The utility model provides a PVC silent drainage pipe. Compared with the existing technology, it has the following advantages:

[0016] 1. This PVC silent drainage pipe has spiral protrusions on the inner wall of the pipe body, which causes turbulence when the water flows through the pipe, thereby breaking up the continuity of the water flow and reducing the noise generated by the water flow impacting the inner wall of the pipe, achieving a silent effect. At the same time, the grooves formed by the protrusions can increase the contact area between the water flow and the air, further reducing noise. In addition, this structure will not affect the drainage efficiency, is easy to install, and has good practicality and economy.

[0017] 2. The PVC silent drainage pipe realizes the function of quick installation and disassembly of the pipe body by arranging a threaded sleeve, an external thread, a fixing ring, a bolt, a fixing block, a connecting plate, a pawl, a fixing plate, a spring, a connecting plate, a connecting shaft and a connecting rod. When connecting two sets of pipe bodies, you only need to rotate the connecting rod to control the tightness of the fixing ring, so that the two sets of pipe bodies can be easily installed and disassembled without looking for tools such as wrenches for operation, which makes the pipe connection quick and improves the effect of pipe disassembly and assembly.

[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0024] See also Figure 1-4The utility model provides a technical solution: a PVC silent drainage pipe, including a pipe body 1, the inner wall surface of the pipe body 1 is provided with multiple groups of protrusions 5. Due to the presence of the protrusions 5, the water flow is broken up into turbulence, reducing the direct impact of the water flow on the inner wall of the pipe, thereby reducing noise. One end of the pipe body 1 is fixedly connected with a threaded sleeve 2, and the end of the threaded sleeve 2 away from the pipe body 1 is rotatably connected with a fixing ring 4, which can better fix and connect multiple groups of pipe bodies 1. The fixing ring 4 is provided with two groups, and the two groups of fixing rings 4 are rotatably connected. The two groups of fixing rings 4 are detachably connected by bolts 6, further strengthening the connection between the multiple groups of pipe bodies 1. One end of the bolt 6 is fixedly connected with a connecting plate 14, and the connecting plate 14 rotates with the bolt 6, and the side of the connecting plate 14 away from the bolt 6 is fixed. The fixed block 7 is fixedly connected, and the fixed block 7 rotates with the connecting plate 14. The internal rotation of the fixed block 7 is connected to the connecting shaft 8. One end of the connecting shaft 8 passes through one side of the fixed block 7 and is rotatably connected to the connecting plate 14. The internal rotation of the fixed block 7 is connected to the pawl 11. The outer side of the connecting shaft 8 is fixedly connected to the ratchet 10. The ratchet 10 and the pawl 11 are used in conjunction with the pawl 11. The pawl 11 limits the rotation direction of the ratchet 10. When the ratchet 10 rotates forward, the pawl 11 limits the rotation of the ratchet 10, so that the connecting shaft 8 rotates while rotating with the fixed block 7. The fixed block 7 rotates with the bolt 6 through the connecting plate 14. When the ratchet 10 rotates forward, the pawl 11 will not limit the rotation of the ratchet 10. The connecting rod 9 rotates with the connecting shaft 8 to adjust the position of the connecting rod 9.

[0025] Furthermore, a fixing plate 12 is fixedly connected to the interior of the fixing block 7, and a spring 13 is provided between one side of the fixing plate 12 and the pawl 11. The ratchet 10 rotates in the opposite direction to squeeze the pawl 11, and the pawl 11 moves with the spring 13. The spring 13 is pulled to generate elastic force. When the spring 13 loses its tension, the spring 13 brings the pawl 11 back to its original position under the action of the elastic force.

[0026] Furthermore, one end of the connecting shaft 8 away from the connecting plate 14 passes through one side of the fixing block 7 and is fixedly connected to a connecting rod 9 , and the connecting rod 9 rotates to rotate the connecting shaft 8 .

[0027] Furthermore, an external thread 3 is provided on the outer side of one end of the pipe body 1 away from the threaded sleeve 2. The external thread 3 at one end of one group of pipe bodies 1 can be screwed into the threaded sleeve 2 of another group of pipe bodies 1 to connect the two groups of pipe bodies 1.

[0028] Furthermore, the bumps 5 are distributed in a spiral shape, breaking up the water flow into turbulent flow, reducing the direct impact of the water flow on the inner wall of the pipe, and thus reducing noise.

[0029] Furthermore, grooves are formed between adjacent protrusions 5, which increases the contact area between water flow and air and further absorbs noise.

[0030] Furthermore, the material of the protrusion 5 and the material of the pipe body 1 are both PVC materials.

[0031] During use, when water flows through the pipe body 1, due to the presence of the protrusions 5, the water flow is broken up into turbulence, reducing the direct impact of the water flow on the inner wall of the pipe, thereby reducing noise. At the same time, the grooves formed between the protrusions 5 increase the contact area between the water flow and the air, further absorbing noise. Therefore, the pipe body 1 can effectively reduce the noise generated during drainage and improve the living environment. When connecting and installing two sets of pipe bodies 1, screw the external thread 3 at one end of one set of pipe bodies 1 into the threaded sleeve 2 of the other set of pipe bodies 1, and then rotate the connecting rod 9. The connecting rod 9 rotates with the connecting shaft 8, and the connecting shaft 8 rotates with the ratchet 10. When the ratchet 10 rotates in the forward direction, the pawl 11 limits the rotation of the ratchet 10, so that the ratchet 10 rotates and drives the connecting plate 14 to rotate through the pawl 11. The connecting plate 14 rotates and drives the bolt 6 to rotate, fixing the two sets of fixing rings 4. When the bolt 6 is tightened, During the tightening process, the existence of an object below restricts the rotation of the connecting rod 9, so that the rotation range of the connecting rod 9 is limited to the top. When the connecting rod 9 is rotated forward, the connecting rod 9 rotates with the connecting shaft 8 and the ratchet 10. When the ratchet 10 is rotated reversely, the pawl 11 will not restrict the rotation of the ratchet 10. The rotation of the ratchet 10 squeezes the pawl 11, and the pawl 11 moves due to the squeezing. The movement of the pawl 11 moves with the spring 13. When the pawl 11 loses the squeezing force, the pawl 11 returns to its original position under the action of the elastic force. When the connecting rod 9 is rotated in the reverse direction to the starting position, the connecting rod 9 can be continued to be rotated forward to tighten the bolt 6. The two sets of fixing rings 4 can be fixed without using tools.
