However, the reserved holes generally have various defects and are not convenient for the installation of the pipes. Therefore, people often use the method of pre-buried sleeves to reserve positions for pipe installation.

In order to prevent debris from falling into the sleeves and clogging them during construction, the ports of the sleeves are generally blocked. The current sleeves are directly blocked with paper, foam, etc., which is unstable and difficult to remove the blocking materials at a later stage. Utility Model Content

[0007] As a preferred embodiment of the above technical solution, the upper pressure driving mechanism includes a movable ring slidably sleeved on the outer wall of the sleeve, and a top block is fixedly connected in an array on the outer wall of the movable ring. The cross-sections of multiple top blocks are all right-angled trapezoidal structures, and the top blocks are narrow at the top and wide at the bottom. A fixed supporting mechanism for supporting the movable ring is provided on the outer wall of the mounting ring.

[0008] In the above solution, the lower auxiliary wheel is pushed by the provided top block, thereby causing the linkage rod to rotate.

DETAILED DESCRIPTION

[0024] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention. Embodiment 1

[0025] like Figure 1 and Figure 4 As shown, the utility model provides a technical solution: a pre-buried casing for building water supply and drainage, including a casing 10, a mounting ring 11 is fixedly sleeved on the outer side of the bottom of the casing 10, a sealing cover 12 is provided on the top cover of the casing 10, a fixing ring 13 is fixedly installed on the outer wall of the top of the casing 10, and the fixing ring 13 is detachably fixed to the casing 10 by screws, so that the fixing ring 13 will not affect the normal use of the casing 10 in the later stage, and a fixing frame 14 is fixedly connected to the outer wall of the fixing ring 13, and a rotating shaft 15 is rotatably connected to the fixing frame 14, and a linkage rod 16 is fixedly connected to the outer wall of the rotating shaft 15, and the top of the linkage rod 16 is rotatably connected to an upper auxiliary wheel 17, and the bottom of the linkage rod 16 is The lower auxiliary wheels 18 are rotatably connected, and an upward pressure driving mechanism for driving the linkage rod 16 to rotate is arranged below the multiple lower auxiliary wheels 18. During specific use, the lower auxiliary wheels 18 are pushed vertically upward by the arranged upward pressure driving mechanism, so that the linkage rod 16 rotates with the rotating shaft 15 as the center, and the upper auxiliary wheels 17 at the top are close to each other, and the distance between the upper auxiliary wheels 17 and the sealing cover 12 is gradually reduced until the upper auxiliary wheels 17 contact the sealing cover 12, so that the sealing cover 12 can be fixed to the sleeve 10 through the upper auxiliary wheels 17. When the sleeve 10 is in use, the fixing ring 13 and the upward pressure driving mechanism can be disassembled without causing a significant impact on the surface of the sleeve 10.

[0026] As an implementation method in this embodiment, Figure 1As shown, the upper pressure driving mechanism includes a movable ring 20 that is slidably sleeved on the outer wall of the sleeve 10, and a top block 21 is fixedly connected in an array on the outer wall of the movable ring 20. The cross-sections of the multiple top blocks 21 are all right-angled trapezoidal structures, and the top blocks 21 are narrow at the top and wide at the bottom. A fixed supporting mechanism for supporting the movable ring 20 is provided on the outer wall of the mounting ring 11. During specific use, the movable ring 20 is manually pushed upward so that the top block 21 on the movable ring 20 contacts the lower auxiliary wheel 18. When the movable ring 20 continues to move upward, the linkage rod 16 rotates with the rotating shaft 15 as the center of the circle, so that the upper auxiliary wheel 17 contacts the sealing cover 12, and the sealing cover 12 is limited and fixed by the upper auxiliary wheel 17. It should be noted that the movable ring 20 is first sleeved on the sleeve 10, and then the fixed ring 13 is sleeved.

[0027] As an implementation method in this embodiment, Figure 1 and Figure 2 As shown, the fixed support mechanism includes an upper limit frame 30 fixed on the outer wall of the movable ring 20 in an annular array and a lower limit frame 31 fixed on the upper end surface of the mounting ring 11 in an annular array, and a support plate 32 is arranged between the upper limit frame 30 and the lower limit frame 31. During specific use, after the upper auxiliary wheel 17 contacts the sealing cover 12, the movable ring 20 no longer moves, and the support plate 32 is inserted between the upper limit frame 30 and the lower limit frame 31 to fix them. This structure can quickly disassemble the sealing cover 12 without causing a significant impact on the outer wall of the sleeve 10.

[0028] As an implementation method in this embodiment, Figure 3 As shown, a plurality of reinforcing plates 40 are fixed in an array on the upper and lower end surfaces of the mounting ring 11, and one side of the plurality of reinforcing plates 40 is fixedly connected to the outer wall of the sleeve 10. The reinforcing effect of the reinforcing plates 40 is transmitted to the entire sleeve 10 structure, effectively enhancing the structural strength of the embedded sleeve 10, and further improving the stability and durability of the entire embedded sleeve 10 system.

[0029] As an implementation method in this embodiment, Figure 3 As shown, a plurality of connecting holes 111 are provided in a circular array on the mounting ring 11. During the installation process, the mounting ring 11 is connected with other fixing devices. By passing bolts, nuts or other fasteners through these connecting holes 111, the mounting ring 11 can be firmly fixed in a predetermined position to ensure that the sleeve 10 will not move or be misplaced.

[0030] Working principle: When in use, first manually push the movable ring 20 upward, so that the top block 21 on the movable ring 20 contacts the lower auxiliary wheel 18. When the movable ring 20 continues to move upward, the linkage rod 16 rotates with the rotating shaft 15 as the center, so that the upper auxiliary wheel 17 contacts the sealing cover 12. The sealing cover 12 is limited and fixed by the upper auxiliary wheel 17. When the sleeve 10 is in use, the fixed ring 13 and the upper pressure drive mechanism can be disassembled without causing a significant impact on the surface of the sleeve 10.

[0031] The above embodiments are only used to illustrate the technical solution of the present invention, but not to limit it.
