Description

Technical Field

[0001] The utility model relates to the technical field of drainage pipes, and particularly relates to a spliced water supply and drainage pipe. Background Technique

[0002] Drainage pipe projects are divided into two types: outdoor pipe projects and indoor pipe projects. Generally, cast iron pipes are used for pipes, but steel pipes or reinforced concrete pipes are also used. The function of drainage pipes is to discharge the dirt and sewage of sanitary equipment outside the building. In order to facilitate maintenance when the pipe is blocked, inspection openings, cleaning openings, etc. are generally provided on the main pipe of the drainage pipe.

[0003] For example, in the Chinese published patent: CN218267769U, a spliced water supply and drainage pipe, which relates to the technical field of drainage pipes, includes an outer water pipe layer A. One end of the outer water pipe layer A is provided with an outer water pipe layer B. Inner water pipe layers are arranged inside both the outer water pipe layer A and the outer water pipe layer B. An annular block A is fixedly installed at one end of the outer water pipe layer A close to the outer water pipe layer B. An annular block B is fixedly installed at one end of the outer water pipe layer B close to the outer water pipe layer A. An annular fixing sleeve is sleeved on the surfaces of the annular block A and the annular block B. A groove is opened on the inner wall of the annular fixing sleeve. In the utility model, through the setting of the annular fixing sleeve, when splicing and installing two drainage pipes, only need to sleeve the annular fixing sleeve on the annular block A and the annular block B, rotate the threaded rod, so that the annular fixing sleeve contracts inward, and the two drainage pipes can be fixed, avoiding the phenomenon of cutting the drainage pipe when repairing the drainage pipe, and making the splicing of the drainage pipe more convenient.

[0004] Although through the coordinated use of the above devices, the problem of cutting the drainage pipe during the maintenance of the drainage pipe can be avoided, but through the installation method of the annular fixing sleeve and the threaded rod, specific tools are required, and the threaded rod needs to be rotated to a corresponding number of turns to achieve installation and disassembly. While the operation is cumbersome, it will also reduce the maintenance efficiency. Therefore, we propose a spliced water supply and drainage pipe. Content of the Utility Model

[0005] The purpose of the utility model is to provide a drainage pipe with convenient installation and disassembly.

[0006] To achieve the above purpose, the utility model provides the following technical solution: It includes a first pipe and a second pipe. An extension pipe inserted into the inner wall of the first pipe is fixedly connected to the side wall of the second pipe. A plug connector is fixedly connected to the side wall of the second pipe. A plug-in slot for the plug connector to be inserted is opened on the side wall of the first pipe. A clamping block is slidably connected to the inner wall of the plug connector. A clamping groove for the clamping block to be clamped is opened on the inner wall of the plug-in slot.

[0007] The outer wall of the first pipe is rotatably connected with a rotating ring, and the inner wall of the rotating ring is slidably connected with a push rod for pushing the clamping block.

[0008] When the first pipe and the second pipe are connected and installed, by slidingly inserting the extension pipe fixedly installed on the outer wall of the second pipe into the inner wall of the first pipe, the connection between the first pipe and the second pipe can be completed. At the same time, the plug connector can be driven to engage with the insertion slot opened on the side wall of the first pipe. By clamping the clamping block sliding on the inner wall of the plug connector with the clamping slot in the inner cavity of the insertion slot, the current positions of the first pipe and the second pipe can be fixed, realizing the installation between the first pipe and the second pipe. The rotating ring can rotate along the outer wall of the first pipe under the influence of the acting force. By driving the push rod to rotate to the directly above the clamping block through the rotating ring and applying a downward acting force to the push rod, the clamping between the clamping block and the clamping slot can be released, and the disassembly between the first pipe and the second pipe can be realized.

[0009] Preferably, a clamping ring is fixedly connected to the inner wall of the rotating ring, and a rotating slot for the clamping ring to slide is opened on the outer wall of the first pipe. The rotating slot communicates with the inner cavity of the insertion slot. When the rotating ring rotates along the outer wall of the first pipe, the clamping ring will rotate along the inner wall of the rotating slot at this time, which can limit the rotation trajectory of the rotating ring.

[0010] Preferably, a limiting slot for the clamping ring to be clamped is opened on the outer wall of the plug connector. Since the rotating slot communicates with the inner cavity of the insertion slot, when the plug connector is inserted into the insertion slot opened on the side wall of the first pipe, the clamping ring can further limit the limiting slot opened on the outer wall of the plug connector, achieving the effect of secondary fixation of the plug connector and improving the stability when the first pipe and the second pipe are connected.

[0011] Preferably, a receiving slot for the clamping block to slide is opened on the inner wall of the plug connector. The bottom end of the clamping block is fixedly connected with a return spring, and the other end of the return spring is fixedly connected with the inner wall of the receiving slot. One end of the clamping block away from the second pipe is set as an inclined surface. When the second pipe is connected to the first pipe, the side wall of the first pipe can press the clamping block arranged on the inclined surface. When the clamping block is pressed, the return spring will deform and store elastic potential energy, and contract into the inner cavity of the plug connector. When the clamping block slides into the inner cavity of the clamping slot, the return spring can release the elastic potential energy to push the clamping block out into the inner cavity of the clamping slot to complete the fixation.

[0012] Preferably, one end of the push rod extends out of the outer wall of the rotating ring and is fixedly connected with a pressing block. The bottom end of the pressing block is fixedly connected with a top pressure spring, and the top pressure spring is fixedly connected with the inner wall of the rotating ring. By applying an acting force to the pressing block, the push rod can be driven to slide synchronously. When the push rod pushes the clamping block back into the inner cavity of the receiving slot, the top pressure spring deforms and stores elastic potential energy at this time. When the push rod no longer receives the acting force, the top pressure spring releases the elastic potential energy to reset the push rod.

[0013] Preferably, positioning holes are provided on both the outer wall of the rotating ring and the second pipe. The clamping ring is provided with a notch directly below the positioning hole. When the first pipe is connected to the second pipe, the insertion joint needs to be inserted into the insertion slot. By aligning the positioning hole provided at the top of the rotating ring with the positioning hole of the second pipe, the notch provided in the clamping ring will not block the insertion joint at this time. Until the clamping block pops out from the inner cavity of the insertion joint and engages with the clamping slot, the installation between the first pipe and the second pipe can be completed. By rotating the rotating ring, the clamping ring further clamps the insertion joint to improve the connection stability. At this time, the push rod cannot push the clamping block. When disassembly is required, the positioning hole provided at the top of the rotating ring needs to be aligned with the positioning hole at the top of the second pipe. At this time, the push rod is directly above the clamping slot. By pressing down the push rod, the engagement between the clamping block and the clamping slot can be released for disassembly.

[0014] Preferably, a sealing ring is fixedly installed on the outer wall of the extension pipe. The sealing ring can improve the sealing performance when the first pipe is connected to the second pipe.

[0015] Compared with the prior art, the beneficial effects of the present utility model are:

[0016] The present utility model connects the first pipe and the second pipe, inserts the insertion joint into the insertion slot, and completes the installation of the first pipe and the second pipe by engaging the clamping block with the clamping slot provided on the inner wall of the insertion slot. By using the push rod to release the engagement between the clamping block and the clamping slot, the pipe can be disassembled, which is convenient for maintaining the first pipe and the second pipe.

[0025] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention. Embodiment 1

[0026] Please refer to Figure 1-7 , a spliced water supply and drainage pipeline shown in the figure, includes a first pipeline 1 and a second pipeline 2. An extension pipe 3 fixedly connected to the side wall of the second pipeline 2 is inserted into the inner wall of the first pipeline 1. A plug connector 7 is fixedly connected to the side wall of the second pipeline 2. An insertion slot 11 for the plug connector 7 to be inserted is opened on the side wall of the first pipeline 1. A block 9 is slidably connected to the inner wall of the plug connector 7, and a clamping groove for the block 9 to be clamped is opened on the inner wall of the insertion slot 11.

[0027] The outer wall of the first pipeline 1 is rotatably connected with a rotating ring 5, and a push rod 6 for pushing the block 9 is slidably connected to the inner wall of the rotating ring 5.

[0028] In this embodiment: When the first pipeline 1 and the second pipeline 2 are connected and installed, by sliding and inserting the extension pipe 3 fixedly installed on the outer wall of the second pipeline 2 into the inner wall of the first pipeline 1, the connection between the first pipeline 1 and the second pipeline 2 can be completed. At the same time, the plug connector 7 can be driven to be engaged with the insertion slot 11 opened on the side wall of the first pipeline 1. By clamping the block 9 sliding on the inner wall of the plug connector 7 with the clamping groove in the inner cavity of the insertion slot 11, the current positions of the first pipeline 1 and the second pipeline 2 can be fixed, realizing the installation between the first pipeline 1 and the second pipeline 2. The rotating ring 5 can rotate along the outer wall of the first pipeline 1 under the influence of force. By driving the push rod 6 to rotate to the directly above the block 9 through the rotating ring 5 and applying a downward force to the push rod 6, the engagement between the block 9 and the clamping groove can be released, and the disassembly between the first pipeline 1 and the second pipeline 2 can be realized.

[0029] Working principle: Connect the first pipe 1 with the second pipe 2, so that the plug connector 7 is inserted into the insertion slot 11 opened on the inner wall of the first pipe 1. The clamping block 9 sliding on the inner wall of the plug connector 7 is engaged with the clamping slot opened on the inner wall of the insertion slot 11, and the installation of the first pipe 1 and the second pipe 2 can be completed. By pushing the push rod 6 to release the engagement between the clamping block 9 and the clamping slot, the pipe can be disassembled, which is convenient for maintaining the first pipe 1 and the second pipe 2. Embodiment 2

[0030] Please refer to Figure 1-7 , this embodiment further illustrates Embodiment 1. In the figure, a clamping ring 8 is fixedly connected to the inner wall of the rotating ring 5, and a rotating groove for the clamping ring 8 to slide is opened on the outer wall of the first pipe 1. The rotating groove is communicated with the inner cavity of the insertion slot 11.

[0031] In this embodiment: When the rotating ring 5 rotates along the outer wall of the first pipe 1, the clamping ring 8 will rotate along the inner wall of the rotating groove at this time, and the rotation trajectory of the rotating ring 5 can be limited.

[0032] Please refer to Figure 1-7 , in the figure, a limiting groove for the clamping ring 8 to be clamped is opened on the outer wall of the plug connector 7.

[0033] In this embodiment: Since the rotating groove is communicated with the inner cavity of the insertion slot 11, when the plug connector 7 is inserted into the insertion slot 11 opened on the side wall of the first pipe 1, the clamping ring 8 can be used to further limit the limiting groove opened on the outer wall of the plug connector 7, achieving the effect of secondary fixation on the plug connector 7 and improving the stability when the first pipe 1 and the second pipe 2 are connected.

[0034] Please refer to Figure 1-7 , in the figure, a receiving groove for the clamping block 9 to slide is opened on the inner wall of the plug connector 7. The bottom end of the clamping block 9 is fixedly connected with a return spring 10, and the other end of the return spring 10 is fixedly connected with the inner wall of the receiving groove.

[0035] In this embodiment: One end of the clamping block 9 away from the second pipe 2 is set as an inclined surface. When the second pipe 2 is connected to the first pipe 1, the side wall of the first pipe 1 can press the clamping block 9 with the inclined surface set. The clamping block 9 is pressed to cause the return spring 10 to deform and store elastic potential energy, and contract into the inner cavity of the plug connector 7. When the clamping block 9 slides into the inner cavity of the clamping slot, the return spring 10 can release the elastic potential energy to push the clamping block 9 out into the inner cavity of the clamping slot to complete the fixation.

[0036] Please refer to Figure 1-7 , in the figure, one end of the push rod 6 extends out of the outer wall of the rotating ring 5 and is fixedly connected with a pressing block. The bottom end of the pressing block is fixedly connected with a top pressure spring 12, and the top pressure spring 12 is fixedly connected with the inner wall of the rotating ring 5.

[0037] In this embodiment: By applying a force to the pressing block, the push rod 6 can be driven to slide synchronously. When the push rod 6 pushes the clamping block 9 back into the inner cavity of the receiving groove, the top pressure spring 12 deforms at this time to store elastic potential energy. When the push rod 6 is no longer subjected to a force, the top pressure spring 12 releases the elastic potential energy to reset the push rod 6.

[0038] Please refer to Figure 1-7 , in the figure, positioning holes are provided on the outer walls of both the rotating ring 5 and the second pipe 2, and a notch is provided in the clamping ring 8 directly below the positioning hole.

[0039] In this embodiment: When the first pipe 1 is connected to the second pipe 2, the socket 7 needs to be inserted into the socket groove 11. By aligning the positioning hole provided at the top of the rotating ring 5 with the positioning hole of the second pipe 2, the notch provided in the clamping ring 8 will not block the socket 7 at this time. Until the clamping block 9 pops out from the inner cavity of the socket 7 and engages with the card slot, the installation between the first pipe 1 and the second pipe 2 can be completed. By rotating the rotating ring 5, the clamping ring 8 further clamps the socket 7 to improve the connection stability. At this time, the push rod 6 cannot push the clamping block 9. When disassembly is required, the positioning hole provided at the top of the rotating ring 5 needs to be aligned with the positioning hole at the top of the second pipe 2. At this time, the push rod 6 is directly above the card slot. By pressing the push rod 6 downward, the engagement between the clamping block 9 and the card slot can be released for disassembly.

[0040] Please refer to Figure 1-7 , in the figure, a sealing ring 4 is fixedly installed on the outer wall of the extension pipe 3.

[0041] In this embodiment: The sealing ring 4 can improve the sealing performance when the first pipe 1 is connected to the second pipe 2.
