For example, "connected" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0025] like Figures 1-4As shown, a pre-installed sleeve device for water supply, drainage, heating and ventilation includes a pre-installed sleeve body 1 and a conical cover 2. The conical cover 2 is disposed on the top surface of the pre-installed sleeve body 1. A support tube 3 is movably sleeved on the inner circular wall of the conical cover 2. The outer circular wall of the support tube 3 is threaded and threaded with a threaded ring 7. A fixing hole 8 is opened on the bottom surface of the support tube 3. A screw 9 is movably sleeved on the inner circular wall of the fixing hole 8. A hexagonal column 12 is fixedly disposed above the screw 9. A connecting column 10 is movably sleeved on the inner circular wall of the support tube 3. A first hexagonal groove 11 is opened on the bottom surface of the connecting column 10.

[0026] Specifically, the conical cover 2 is placed on top of the pre-reserved sleeve body 1. Its hollow circular wall is movably fitted with the support tube 3, allowing the conical cover 2 to move up and down relative to each other. The support tube 3 is located inside the conical cover 2, and its outer circular wall is threaded, connecting with the threaded ring 7 via a threaded engagement. A fixing hole 8 is opened on its bottom surface, and its hollow circular wall is movably fitted with the connecting post 10. The connecting post 10 is located inside the support tube 3 and movably fitted with the inner circular wall of the support tube 3. A first hexagonal groove 11 is opened on its bottom surface for movably fitting with the hexagonal post 12. When using this device, first place the bottom of the support tube 3 at the installation center point of the template, then insert the connecting post 10 into the support tube 3, so that the first hexagonal groove 11 on the bottom surface of the connecting post 10 fits with the hexagonal post 12 above the screw 9. Using a tool, the connecting column 10 is tightened. Since the connecting column 10 is fitted with the hexagonal column 12, it causes the hexagonal column 12 and the screw 9 fixed thereto to rotate. The screw 9 is screwed into the template, thus fixing the support pipe 3 onto the template, achieving initial support and positioning of the entire device. By tightening the threaded ring 7, which is threaded to the outer wall of the support pipe 3, the threaded ring 7 moves downward along the outer wall of the support pipe 3. Because the support pipe 3 is movably fitted with the conical cap 2, the downward pressing action of the threaded ring 7 indirectly applies pressure to the top surface of the reserved sleeve body 1 by the conical cap 2, firmly limiting the reserved sleeve body 1 onto the template and preventing displacement of the reserved sleeve body 1 during subsequent construction, ensuring accurate positioning of the reserved sleeve. By setting the screw 9, it is movably fitted into the fixing hole 8 on the bottom surface of the support pipe 3, causing the screw 9 to rotate and drill into the template, thus fixing the support pipe 3 firmly onto the template, providing a reliable support foundation for the entire device. By setting up a support tube 3, a threaded ring 7, and a conical cover 2, rotating the threaded ring 7 drives the conical cover 2 to move downward, thus firmly limiting the reserved sleeve body 1 on the template; the overall structure of the device is simple, thereby reducing costs, making it less prone to damage, and easy to operate.

[0027] like Figure 2 , 3As shown in Figure 4, the outer circular wall of the support tube 3 is provided with a plurality of limiting holes 4, and a connecting frame 6 is movably sleeved inside the limiting holes 4. A limiting plate 5 is fixedly installed on the top surface of the conical cover 2. The limiting plate 5 is movably sleeved with the support tube 3, and the limiting plate 5 is fixedly installed with the connecting frame 6.

[0028] Specifically, the limiting hole 4 on the outer circular wall of the support pipe 3 is movably connected to the connecting frame 6, while the connecting frame 6 is fixedly installed to the limiting plate 5 fixed on the top surface of the conical cover 2. This connection method tightly connects the conical cover 2 and the support pipe 3 together. When the device is subjected to external forces, such as the impact force during concrete pouring, the components can work together to bear the force, avoiding instability of the overall structure due to loose connections between components, and greatly enhancing the stability of the entire reserved sleeve device.

[0029] like Figure 4 As shown, a gasket 16 is provided on the bottom surface of the threaded ring 7. The gasket 16 is movably sleeved with the support tube 3 to prevent the threaded connection from loosening and to ensure that it remains in a tight state.

[0030] like Figure 2 , 4 As shown, several rotating plates 15 are fixedly installed on the outer circular wall of the threaded ring 7.

[0031] Specifically, in this embodiment, four rotating plates 15 are provided. The rotating plates 15 provide operators with more convenient points of force application. By holding the rotating plates 15, torque can be applied more easily to rotate the threaded ring 7, which not only reduces the difficulty of operation but also improves work efficiency.

[0032] like Figure 2 As shown, the outer circular wall of the limiting plate 5 is threaded with a protective cover 13.

[0033] Specifically, the protective cover 13 can effectively block external pollutants such as dust and debris from entering the device, ensuring normal movement between components and preventing jamming or wear.

[0034] like Figure 3 As shown, several conical heads 14 are fixedly installed on the bottom surface of the support tube 3.

[0035] Specifically, the special shape of the conical head 14 makes its contact with the template not a smooth planar contact, which can significantly increase the friction of the support tube 3 on the template, effectively prevent the support tube 3 from sliding or shifting, ensure the positional stability of the entire device, and help to accurately install the reserved sleeve body 1.

[0036] The above-described embodiments of this utility model achieve the following technical effects: When the user needs to install and fix the pre-reserved sleeve body 1, firstly, the center point of the installation position of the pre-reserved sleeve body 1 on the template is determined, and the pre-reserved sleeve body 1 is placed at the center point of the template. Then, the support pipe 3 is placed inside the pre-reserved sleeve body 1, and its bottom surface is placed on the template to be poured concrete, with the bottom at the installation center point. Next, the connecting column 10 is inserted into the support pipe 3 and passes downward through the connecting frame 6 so that the first hexagonal groove 11 engages with the hexagonal column 12. Using a tool, the connecting column 10 is turned, causing the connecting column 10 to rotate, which in turn rotates the bottom hexagonal column 12 and the screw 9, causing the rotating screw 9 to rotate and insert into the interior of the template. The screw 9 fixes the support pipe 3, and the conical head 14 increases the friction between the support pipe 3 and the template. Force is applied, and then the rotating plate 15 is turned to drive the threaded ring 7 to rotate downward outside the support pipe 3, pressing down the limiting plate 5. This causes the conical cover 2 to press down on the top surface of the reserved sleeve body 1, thus limiting the reserved sleeve body 1 by pressing down on it. This prevents the reserved sleeve body 1 from being pushed or displaced during concrete pouring, ensuring the accurate position of the reserved sleeve body 1. The protective cover 13 is screwed onto the outer wall of the limiting plate 5 for protection. After use, the protective cover 13 is removed, and the connecting column 10 is turned to rotate the screw 9 out of the template to remove the conical cover 2. The screw 9 is inserted into the template to fix the support pipe 3 and the conical cover 2. The threaded ring 7 is turned down to fix the reserved sleeve body 1. Disassembly is done by reversing the operation. This reduces structural complexity, thereby reducing costs, making it less prone to damage, convenient to use, and quite practical.

[0037] 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 claims.
