Two sets of sealing ring gaskets 6 are fixedly installed on the inner side of the inner support end seat 4 and the outer support end seat 5 respectively. The threaded fastening force between the inner support sleeve 1 and the telescopic sleeve 3 can provide clamping and fastening force for the installation of the sleeve. With the contact sealing of the sealing ring gaskets 6 on the inner side of the inner support end seat 4 and the outer support end seat 5, the contact support stability and waterproof sealing of the sleeve installation side can be effectively improved, which is conducive to improving the working installation stability and sealing protection of the sleeve.

[0028] The telescopic sleeve 3 serves as a telescopic connection structure between the inner support sleeve 1 and the outer support sleeve 2. The front end of the telescopic sleeve 3 is threaded to the end of the inner support sleeve 1, as detailed in the attached diagram. Figure 5 As shown, to achieve threaded installation, mating threads are provided on the inner circumference of the rear part of the inner support sleeve 1 and the outer circumference of the front part of the telescopic sleeve 3. The front end of the telescopic sleeve 3 is connected to the threaded rear inner cavity of the inner support sleeve 1 through the mating threads. To achieve telescopic mating installation, as shown in the attached figure... Figure 3 As shown, a fitting positioning block 7 is provided at the rear of the telescopic sleeve 3. Four fitting positioning blocks 7 are provided, evenly distributed in a circular pattern and fixedly installed on the outer rear circumference of the telescopic sleeve 3. For proper installation, as shown in the attached diagram... Figure 4As shown, an engagement guide groove 8 is provided on the inner circumference of the outer support sleeve 2. The engagement guide groove 8 is located on the inner circumference of the outer support sleeve 2 and is adapted to the engagement positioning block 7. During installation, the engagement positioning block 7 and the outer support sleeve 2 are slidably engaged. The rear end of the telescopic sleeve 3 is movably inserted into the inner cavity of the outer support sleeve 2 through the sliding guidance of the engagement positioning block 7 and the engagement guide groove 8. A telescopic installation structure is adopted. A telescopic sleeve 3 is provided between the inner support sleeve 1 and the outer support sleeve 2. The telescopic sleeve 3 is movably installed with the engagement guide groove 8 on the inner side of the outer support sleeve 2 through the engagement positioning block 7 at its end. The overall installation length of the sleeve can be conveniently and flexibly adjusted by telescopic adjustment, so that the through-wall protective sleeve can meet the through-wall installation requirements of walls of different thicknesses without the need for pipe cutting.

The telescopic sleeve 3, after telescopic adjustment, is engaged by the slot. The bolts are tightened to lock and limit the movement. Axial extension and contraction are limited by the engagement of the fitting positioning block 7 and the side positioning slot 9 of the fitting guide groove 8 at the inner telescopic end. Multiple positioning slots 9 are provided, allowing for multi-segment length control and adjustment through alignment and engagement. Combined with the threaded tightening and pushing of the inner support sleeve 1 at the end side, stable locking and limiting between the adjusted telescopic sleeve 3 and the outer support sleeve 2 can be achieved. The structure is simple and easy to install. For convenient screwing operation of the outer support sleeve 2, see attached... Figure 5 As shown, an auxiliary recess 10 is provided on the outer end side of the inner support end seat 4. There are four auxiliary recesses 10, which are evenly distributed in a circular shape on the outer end side of the inner support end seat 4. When the outer support sleeve 2 is locked and installed, the rotational force is achieved by inserting the auxiliary recesses 10 into the two sets of locking pins at the end of the special tool, which can facilitate the rotational locking operation of the outer support sleeve 2.

[0030] Working principle or structural principle: During installation, firstly, a wall drilling tool is used to create the perforation. Then, the inside and edges of the perforation are cleaned to remove dust and debris. The outer support sleeve 2 is installed inside the perforation in the cavity wall and secured by hand. Next, the telescopic sleeve 3 is installed on the end of the inner support sleeve 1. Then, the fitting positioning block 7 on the end of the telescopic sleeve 3 is aligned with the fitting guide groove 8 on the end of the outer support sleeve 2. The fitting positioning block 7 and fitting guide groove 8 are aligned and fitted, and the installation position of the telescopic sleeve 3 is adjusted by sliding and telescopic movement. This telescopic adjustment allows for convenient and flexible adjustment of the overall installation length of the sleeve, enabling the through-wall sleeve to meet the installation needs of walls of different thicknesses without the need for pipe cutting, thus avoiding material waste. To effectively reduce the difficulty of sleeve construction and installation, a gap of about one finger is left between the inner support end seat 4 and the inner wall. The corresponding positioning slot 9 is found by telescopic adjustment. Then, the fitting positioning block 7 is fitted and locked with the positioning slot 9 by rotating the pin clockwise. Then, the inner support end seat 4 is rotated and the inner support sleeve 1 is tightened with bolts to bring the inner support end seat 4 close to the inner wall. Then, the inner support end seat 4 is tightened and locked with the auxiliary concave hole 10 and a special tool with double locking posts. After installation, the inner sides of the inner support end seat 4 and the outer support end seat 5 are pressed against the wall by the sealing ring gasket 6. After the installation is completed, the entire sleeve is fixed and limited, and the installation work is completed. Then, a protective cotton sleeve is added to the inside of the sleeve and the air conditioning pipe is connected and installed. Finally, the inner and outer end holes of the sleeve are sealed to complete the pipe installation work.

[0031] In summary, this through-wall sleeve adopts a telescopic installation structure. A telescopic sleeve 3 is installed between the inner support sleeve 1 and the outer support sleeve 2. The telescopic sleeve 3 is movably installed with the inner side of the outer support sleeve 2 via the fitting positioning block 7 at its end. The overall installation length of the sleeve can be easily and flexibly adjusted by telescopic adjustment, so that the through-wall sleeve can meet the through-wall installation requirements of walls of different thicknesses without the need for pipe cutting. This avoids material waste and effectively reduces the difficulty of sleeve construction and installation. After telescopic adjustment, the telescopic sleeve 3 is locked and limited by the slotted hole clamping and bolt fastening clamp. The inner telescopic end is connected to the fitting guide groove 8 via the fitting positioning block 7. The side positioning slot 9 is used for axial telescopic limit by interlocking. The positioning slot 9 is provided with multiple slots that can control and adjust the length of the sleeve in multiple sections by interlocking. With the threaded fastening and pushing of the inner support sleeve 1, the telescopic sleeve 3 and the outer support sleeve 2 can be stably locked and limited after adjustment. The structure is simple and easy to install. In addition, the threaded fastening force between the inner support sleeve 1 and the telescopic sleeve 3 can also provide clamping and fastening force for the installation of the sleeve. With the contact sealing of the inner support end seat 4 and the inner side sealing ring gasket 6 of the outer support end seat 5, the contact support stability and waterproof sealing of the sleeve installation side can be effectively improved, which is conducive to improving the working installation stability and sealing protection of the sleeve.
