Description

Technical Field

[0001] The utility model relates to the technical field of drainage pipes, in particular to an embedded water supply and drainage pipe. Background Art

[0002] Embedded plumbing systems embed plumbing into building structures or the ground to reduce exposed piping, achieving aesthetic appeal, space savings, and improved system safety. This design is commonly used in modern buildings, particularly high-rises, underground projects, and industrial facilities, which require a rationally designed and efficiently operated plumbing system.

[0003] The existing patent with publication number CN221422139U proposes an embedded water supply and drainage pipe. The sewage entering the discharge pipe is filtered through the filter structure 1 installed on the top of the discharge pipe to filter the impurities in the sewage. The filtered impurities fall into the C-shaped external pipe and are drained through the filter structure 2, thereby avoiding drainage blockage, ensuring the drainage efficiency of the embedded water supply and drainage pipe, and being easy to maintain and highly practical.

[0004] However, after the pipeline is installed, the sealing sleeve is welded, which makes it impossible to quickly remove the filter component, making it difficult to install or replace it later. Utility Model Content

[0010] Preferably, a fixing plate is provided on one side of the mounting member, a second bolt is provided inside the fixing plate, and an output end of the second bolt passes through a thread of the fixing plate and enters into the interior of the mounting member.

[0011] Preferably, a soft cushion is fixedly provided on the upper end of the filter seat.

[0012] Compared with the prior art, the beneficial effects of the present invention are:

[0013] 1) By providing a docking structure, when the mounting part needs to be removed from between the first component and the second component for replacement, the extrusion rod is pressed to move the movable inner tube downward in a sealed manner, thereby achieving quick lateral removal, speeding up installation and reducing operational difficulty.

[0014] 2) By providing the docking block, docking groove, first bolt and locking hole, the filter seat can be installed in a guided and fixed manner, thereby ensuring the stability of the filter seat after installation and facilitating the removal of the filter seat at a later time.

DETAILED DESCRIPTION

[0021] 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.

[0022] Example 1

[0023] Combine Figure 1-Figure 5 , an embedded water supply and drainage pipe, comprising a first component 1 and a second component 2, a mounting part 3 is provided between the first component 1 and the second component 2, a fixed pipe 4 is fixedly provided inside the mounting part 3, and a docking structure 6 is provided between the upper and lower ends of the fixed pipe 4 and the first component 1 and the second component 2, the docking structure 6 includes a movable inner tube 5 movably arranged on the inner wall of the fixed tube 4, a movable cavity 8 is opened on both sides of the mounting part 3, an extrusion rod 7 is fixedly provided on both sides of the movable inner tube 5, a vertical rod 9 is fixedly provided inside the movable cavity 8, one end of the extrusion rod 7 enters the movable cavity 8 and is movably sleeved on the outer wall of the vertical rod 9, a spring 10 is sleeved on the outer wall of the vertical rod 9 at the lower end of the extrusion rod 7, a sealing ring 11 is fixedly provided on the outer wall of the movable inner tube 5, the outer wall of the sealing ring 11 is fitted with the inner wall of the fixed tube 4, and a filter seat 14 is fixedly provided on the inner wall of the fixed tube 4, and a card groove 12 is opened on one end of the first component 1 and the second component 2 close to the fixed tube 4.

[0024] See Figure 1 and Figure 5 , it is further obtained that a docking groove 16 is provided on one side of the mounting member 3, a docking block 15 is fixedly provided on one side of the lower end of the filter seat 14, a first bolt 18 is provided with an internal thread of the docking block 15, a locking hole 17 is provided at the bottom end of the docking groove 16, the first bolt 18 enters the interior of the locking hole 17, a pull rod is fixedly provided on one side of the filter seat 14, a fixing plate 20 is provided on one side of the mounting member 3, a second bolt 21 is provided inside the fixing plate 20, the output end of the second bolt 21 passes through the fixing plate 20 and threads into the interior of the mounting member 3, and a soft pad 19 is fixedly provided on the upper end of the filter seat 14.

[0025] Specifically, the docking groove 16 facilitates the installation of the docking block 15. After the first bolt 18 enters the locking hole 17, the filter seat 14 is securely installed. After the first bolt 18 is removed, the pull rod can speed up the pulling out of the filter seat 14. The second bolt 21 is used to fix the fixing plate 20 to the mounting member 3.

[0026] Example 2

[0027] See Figure 3 On the basis of the first embodiment, it is further obtained that a sealing gasket 13 is fixedly provided on the upper end of the inner wall of the card slot 12 , and the upper end of the movable inner tube 5 contacts the lower end of the sealing gasket 13 .

[0028] Specifically, the sealing gasket 13 ensures the sealing between the upper end of the movable inner tube 5 and the upper end of the clamping groove 12 , thereby preventing water from leaking from the contact point between the first component 1 and the movable inner tube 5 .

[0029] During actual operation, water flows downward through the first component 1 and then through the filter seat 14 to the second component 2. When the mounting member 3 needs to be removed, both hands simultaneously press the extrusion rod 7 inward, so that the extrusion rod 7 drives the movable inner tube 5 to hide inside the fixed tube 4. At this time, the movable inner tube 5 drives the sealing ring 11 downward, so that one end of the movable inner tube 5 moves out of the slot 12. After moving out, the mounting member 3 is pulled horizontally, so that the mounting member 3 is separated from between the first component 1 and the second component 2.

[0030] After separation, remove the second bolt 21, so that the second bolt 21 is separated from one side of the mounting member 3, remove the first bolt 18 again, so as to realize the removal of the first bolt 18, pull the pull rod, so as to realize the separation of the filter seat 14, and clean the impurities inside the filter seat 14 after separation.
