[0035] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0036] Specific implementation examples are given below.

[0037] Example 1:

[0038] Please see Figures 1 to 5 The present invention provides a reserved sleeve structure for water supply, drainage, heating and ventilation, including: sleeve 1, adjustment component 3, fixing component 4, sealing component 5, and support frame 2 sleeved on the outside of sleeve 1.

[0039] In this embodiment, the position and angle of the sleeve 1 are adjusted by adjusting component 3, so that the position of the sleeve 1 can be adjusted according to the needs of subsequent projects. Then, the sleeve 1 is fixed by fixing component 4 to ensure the stability of the sleeve 1 and prevent the position of the sleeve 1 from shifting when pouring concrete. The sealing component 5 prevents concrete from falling into the sleeve 1 and affecting the subsequent installation of water supply, drainage and heating systems.

[0040] Example 2:

[0041] Based on Embodiment 1, an adjustment component 3 is further disclosed. The adjustment component 3 is installed on the outside of the support frame 2 and is used to adjust the position of the sleeve 1.

[0042] like Figure 1 , Figure 3 , Figure 4 and Figure 5 As shown, the adjustment component 3 includes: an adjustment ring 301 slidably connected to the outer side of the left and right ends of the support frame 2; an adjustment nut 302 threadedly connected to the right side of the adjustment ring 301; a fixing block 303 rotatably connected to the lower end of the adjustment nut 302; a locking ring 304 rotatably connected to the side of the adjustment ring 301 near the central axis; a locking nut 305 threadedly connected to the side of the locking ring 304 near the central axis; a push block 306 rotatably connected to the side of the locking nut 305 away from the central axis; and a locking block 307 abutting the lower end of the push block 306.

[0043] In this embodiment, when the position of the sleeve 1 needs to be adjusted, the adjusting nut 302 is turned, causing the fixing block 303 to slide, thus disengaging the fixing block 303 from the support frame 2 and releasing the lock on the adjusting ring 301. Then, the adjusting ring 301 is slid. As the adjusting ring 301 slides, the locking ring 304 also slides synchronously, thereby causing the sleeve 1 to slide and adjusting the position of the sleeve 1. This facilitates adjusting the position of the sleeve 1 according to project requirements and facilitates subsequent installation of water supply, drainage, and HVAC systems. When the angle of the sleeve 1 needs to be adjusted, the locking ring 301 is released, and the locking nut 305 is turned. The locking nut 305 causes the push block 306 to slide, releasing the lock on the locking block 307 and the lock on the locking ring 304. Then, the adjusting rings 301 on both sides are slid, creating a certain height difference between the two adjusting rings 301. Simultaneously, the locking ring 304 rotates on the adjusting ring 301 and slides on the sleeve 1 to adjust the angle of the sleeve 1. After the angle adjustment is completed, tighten the adjusting nut 302 to drive the fixing block 303 to slide, so that the fixing block 303 fits against the support frame 2, thereby locking the adjusting ring 301. At the same time, tighten the locking nut 305 to drive the push block 306 to slide. The side of the push block 306 away from the central axis and the upper end of the locking block 307 are both designed with a slope. When the push block 306 slides into the locking ring 304, it will squeeze the locking block 307 to slide downward, so that the locking block 307 fits against the sleeve 1, thereby locking the locking ring 304. This improves the stability of the sleeve 1 after the position adjustment, avoids the sleeve from loosening and causing positional deviation, and affects subsequent use. It is convenient to adjust the position and angle of the sleeve 1 according to engineering requirements and is suitable for different usage situations.

[0044] Example 3:

[0045] Based on Embodiment 1, a fixing component 4 is further disclosed. The fixing component 4 is installed at the upper and lower ends of the support frame 2 and is used to support the sleeve 1.

[0046] like Figure 1 and Figure 3 As shown, the fixing component 4 includes: a fixing nut 401 rotatably connected to the middle of the upper and lower ends of the support frame 2; a fixing rod 402 fixedly installed on the front and rear sides of the upper and lower ends of the support frame 2; a fixing plate 403 slidably connected to the outside of the fixing rod 402; and a top plate 404 fixedly installed on the side of the fixing plate 403 near the central axis.

[0047] In this embodiment, after the angle of the sleeve 1 is adjusted, the fixing nut 401 is rotated. The outer side of the fixing nut 401 is threadedly connected to the fixing plate 403. As the fixing nut 401 rotates, the fixing plate 403 slides on the outer side of the fixing rod 402, thereby causing the top plate 404 to slide, so that the top plate 404 is released from the sleeve 1, thus locking the sleeve 1. Two top plates 404 are installed on the fixing plate 403. Even if the angle of the sleeve 1 is adjusted, one top plate 404 can still contact the sleeve 1 to lock the sleeve 1, ensuring the stability of the sleeve 1 and preventing the sleeve 1 from shifting due to impact when the mud is poured in.

[0048] Example 4:

[0049] Based on Embodiment 1, a sealing component 5 is further disclosed. The sealing component 5 is installed inside the sleeve 1 and is used to seal the sleeve 1.

[0050] like Figure 1 and Figure 2 As shown, the sealing component 5 includes: a dust cover 501 overlapping the left and right sides of the sleeve 1; a sealing ring 502 is fixedly installed on the side of the dust cover 501 near the central axis; a locking block 503 is fixedly installed on the left and right sides inside the sleeve 1; a locking groove 504 is formed on the outer side of the sealing ring 502; and a handle 505 is fixedly installed on the side of the dust cover 501 away from the central axis.

[0051] In this embodiment, after fixing the sleeve 1, the sealing ring 502 on the dust cover 501 is inserted into the sleeve 1, and the locking block 503 is locked into the slot 504. Then, the dust cover 501 is rotated, which drives the sealing ring 502 to rotate, so that the locking block 503 is fully locked into the slot 504, thereby locking the dust cover 501 and preventing mud from entering the sleeve 1, causing blockage in the sleeve 1, which would affect the subsequent use of the sleeve 1. At the same time, after the mud has slightly solidified, the dust cover 501 is pulled out by the handle 505 to prevent the mud from solidifying and sticking to the dust cover 501 and the sleeve 1.

[0052] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
