Specific implementation manner
[0021] The present utility model will be further described in detail below with reference to the accompanying drawings.
[0022] Please refer to Figures 1 to 5 , to achieve the above object, the present utility model provides the following technical solution: A wall-piercing sleeve cover structure for air-conditioning assembly, including a substrate 1, wherein the substrate 1 serves as the basic structure of the entire wall-piercing sleeve cover. There is a mounting hole 2 in the middle of the substrate 1 for accommodating the air-conditioning pipe 3 to pass through; an activity slot 4 communicating with the mounting hole 2 is opened on the side of the substrate 1, and the activity slot 4 is used to accommodate a fixed block 5 adapted thereto. The fixed block 5 in the activity slot 4 can move along the activity slot 4 as needed to adjust its position relative to the substrate 1; a first semi-circular sleeve position 6 is provided at the rear end of the substrate 1, wherein one end of the first semi-circular sleeve 6 is fixedly connected to the substrate 1, and the inner diameter of the first semi-circular sleeve 6 is equivalent to the aperture of the mounting hole 2; the first semi-circular sleeve 6 is used to wrap a part of the air-conditioning pipe 3 to provide a preliminary fixing and sealing effect; the second semi-circular sleeve 7 is arranged on the side of the fixed block 5 close to the first semi-circular sleeve 6 and above the opening of the first semi-circular sleeve 6, and the second semi-circular sleeve 7 is fixedly connected to the first semi-circular sleeve 6. When the two are combined, they jointly form a complete circular sleeve for more tightly wrapping the air-conditioning pipe 3 to enhance the fixing and sealing effects; several positioning card boards 8 are provided on the side of the substrate 1 close to the first semi-circular sleeve 6, and these positioning card boards 8 are distributed in a ring with the mounting hole 2 as the center. The positioning card boards 8 are used to provide accurate positioning during the installation process to ensure that the wall-piercing sleeve cover can be accurately placed in the wall hole and fit tightly with the wall hole.
[0023] During installation, first pass the air-conditioning duct 3 through the wall hole and place it in the installation hole 2 of the base plate 1. According to the diameter of the air-conditioning duct 3 and the size of the wall hole, adjust the distance between the second semi-circular collar 7 and the first semi-circular collar 6 by moving the position of the fixing block 5 in the movable slot 4 to ensure that they can tightly wrap around the air-conditioning duct 3. Fix the adjusted fixing block 5, second semi-circular collar 7 and the first semi-circular collar 6 to form a complete circular collar that tightly wraps around the air-conditioning duct 3. Using the positioning card board 8 as a guide, accurately place the wall-piercing sleeve cover in the wall hole to ensure that the collar fits tightly with the air-conditioning duct 3, and the positioning card board 8 contacts the edge of the wall hole to provide additional fixing effect. Finally, check whether the installation of the wall-piercing sleeve cover is firm to ensure that there is no loosening or falling off, effectively preventing the air-conditioning duct 3 from falling out of the wall hole, while ensuring the indoor and outdoor sealing performance to prevent outdoor wind from flowing back and small animals from invading.
[0024] Please refer to Figure 3 、 Figure 4 As an embodiment of the present utility model, a guiding slider 9 is provided on the inner side wall of the movable slot 4, and sliding grooves 10 adapted to the guiding slider 9 are formed on both sides of the fixing block 5.
[0025] In the above-mentioned solution, the guiding slider 9 plays a role of guiding and positioning. The design of the guiding slider 9 should ensure that the fixing block 5 can maintain stability during sliding to prevent it from shifting or tilting. The sliding grooves 10 are formed on both sides of the fixing block 5, and their shapes and sizes match those of the guiding slider 9. The design of the sliding grooves 10 allows the fixing block 5 to slide smoothly along the guiding slider 9, thereby achieving precise adjustment.
[0026] When it is necessary to adjust the position of the fixing block 5 to adapt to air-conditioning ducts 3 with different diameters, the user can manually push the fixing block 5 to slide along the movable slot 4. During the sliding process, the sliding grooves 10 on both sides of the fixing block 5 will closely cooperate with the guiding slider 9 to ensure that the fixing block 5 remains stable during sliding without shifting or tilting. The user can slide the fixing block 5 to a suitable position according to needs so that the second semi-circular collar 7 can closely cooperate with the first semi-circular collar 6 and wrap around the air-conditioning duct 3. After the installation is completed, the combination of the guiding slider 9 and the sliding grooves 10 will ensure that the fixing block 5 remains in the correct position and provides a stable fixing effect for the wall-piercing sleeve cover.
[0027] Please refer to Figures 2 to 5, as an embodiment of the present utility model, the inner diameter of the second semi-circular ring 7 is equivalent to that of the first semi-circular ring 6. The two sides of the open end below the second semi-circular ring 7 are respectively provided with limit card slots 11, and the depth of the limit card slots 11 is equivalent to the thickness of the first semi-circular ring 6. The upper end of the first semi-circular ring 6 is arranged in the limit card slots 11, and the outer wall of the first semi-circular ring 6 is in close fit with the inner wall of the limit card slots 11.
[0028] In the above-mentioned solution, the inner diameter of the second semi-circular ring 7 is equivalent to that of the first semi-circular ring 6, which means that when the two are combined, they can jointly form a complete circular ring, the inner diameter of which matches the diameter of the air-conditioning duct 3. By respectively arranging limit card slots 11 on both sides of the open end below the second semi-circular ring 7, the depth of the limit card slots 11 is designed to be equivalent to the thickness of the first semi-circular ring 6 to ensure that the first semi-circular ring 6 can be completely embedded therein.
[0029] During assembly, the user slides the fixing block 5 along the movable slot 4 to a suitable position so that the second semi-circular ring 7 can be aligned with the first semi-circular ring 6. After the second semi-circular ring 7 is aligned with the first semi-circular ring 6, it is convenient for the upper end part of the first semi-circular ring 6 to be embedded into the limit card slots 11 below the second semi-circular ring 7. When the upper end of the first semi-circular ring 6 is completely embedded in the limit card slots 11, its outer wall will be in close fit with the inner wall of the limit card slots 11. This close fit not only ensures the overall stability and strength of the ring, but also enhances the sealing performance between the ring and the air-conditioning duct 3. Since the fixing block 5 can slide in the movable slot 4, the user can adjust the position of the second semi-circular ring 7 as needed to adapt to air-conditioning ducts 3 with different diameters. Once adjusted to a suitable position, the close fit between the second semi-circular ring 7 and the first semi-circular ring 6 will ensure that they can stably wrap around the air-conditioning duct 3 and prevent it from falling off from the wall hole.
[0030] Please refer to Figure 4 、 Figure 5 , as an embodiment of the present utility model, a rubber pad 12 is provided on the inner wall of the limit card slots 11, and anti-slip lines 13 are provided on the surface of the rubber pad 12.
[0031] In the above-described solution, by providing a rubber pad 12 on the inner wall of the limit card slot 11, the rubber pad 12, as a material with good flexibility and wear resistance, can adapt to slight dimensional changes while providing additional sealing and friction; the surface of the rubber pad 12 is designed with anti-slip lines 13, where the anti-slip lines 13 can increase the friction between the rubber pad 12 and the first semi-circular collar 6, thereby preventing the first semi-circular collar 6 from accidentally sliding or falling off during use; the elasticity of the rubber pad 12 can fill the tiny gaps that may exist between the first semi-circular collar 6 and the limit card slot 11, thereby providing a tighter fit and better sealing effect, which helps prevent dust, moisture, or other debris from entering the wall hole and keeps the indoor environment clean and dry.
[0032] Furthermore, the design of the anti-slip lines 13 on the surface of the rubber pad 12 can increase the friction with the first semi-circular collar 6. When the first semi-circular collar 6 is inserted into the limit card slot 11, the anti-slip lines 13 can ensure a stable connection between the two, preventing loosening or falling off caused by vibration, temperature changes, or other factors; moreover, the flexibility and elasticity of the rubber pad 12 enable it to adapt to a certain degree of dimensional changes; for example, when the air-conditioning duct 3 expands or contracts slightly due to temperature changes, the rubber pad 12 can accommodate these changes to ensure that the wall-piercing sleeve cover can still tightly wrap around the air-conditioning duct 3; the design of the rubber pad 12 also makes the installation and adjustment process of the wall-piercing sleeve cover more convenient. The user only needs to insert the first semi-circular collar 6 into the limit card slot 11, and the elasticity and anti-slip lines 13 of the rubber pad 12 will automatically complete the positioning and fixing work without additional tools or fasteners.
[0033] Please refer to Figure 2 、 Figure 3 As an embodiment of the present utility model, one end of the positioning card plate 8 is fixedly connected to the substrate 1, and a wedge-shaped block 14 is provided at the other end of the positioning card plate 8.
[0034] In the above-described solution, the main function of the positioning card board 8 is to provide additional support and positioning functions. One end of the positioning card board 8 is fixedly connected to the base plate 1, and a wedge-shaped block 14 is provided at the other end of the positioning card board 8; the wedge-shaped block 14 is usually in an inclined plane shape and can generate a self-locking effect when inserted into the wall hole; during use, by aligning the wedge-shaped block 14 with the hole in the wall and inserting the wedge-shaped block 14 into the hole with force, due to the inclined plane design of the wedge-shaped block 14, an inward pressure will be generated during the insertion process, thereby ensuring that the entire sleeve structure is firmly fixed to the wall. After inserting the wedge-shaped block 14, it is necessary to check the stability of the entire structure. The stability can be checked by gently shaking the wall-piercing sleeve cover to see if there is any looseness or shaking. If an unstable situation is found, it is necessary to reinstall the positioning card board 8 or adjust the position of the wedge-shaped block 14 until a stable effect is achieved; through the combined use of the positioning card board 8 and the wedge-shaped block 14, a simple and effective way is provided to ensure the stable installation and precise positioning of the wall-piercing sleeve cover or other structures. At the same time, due to the self-locking effect of the wedge-shaped block 14, this design can also resist the impact and vibration of external forces to a certain extent, thereby improving the stability and safety of the entire structure.
[0035] Please refer to Figure 2 、 Figure 3 As an embodiment of the present invention, an annular rubber strip 15 is provided along the circumference of the rear end of the base plate 1.
[0036] In the above-described solution, the annular rubber strip 15 is a flexible sealing element provided along the circumference of the rear end of the base plate 1. The annular rubber strip 15 is usually made of a rubber material that is wear-resistant, aging-resistant, and has good elasticity; the inner diameter and outer diameter of the annular rubber strip 15 are determined according to the design and requirements of the base plate 1 to ensure that it can closely fit between the rear end of the base plate 1 and the wall hole to be sealed; the main function of the annular rubber strip 15 is to provide a sealing effect to prevent liquids, gases, or other media from leaking through the gap between the rear end of the base plate 1 and the sealed object. Due to the elasticity of the rubber material, the annular rubber strip 15 can adapt to a certain degree of size change and shape difference to ensure good sealing performance under various working conditions.
[0037] Although the specific embodiments of the present invention have been described above, those skilled in the art should understand that these are only examples. The protection scope of the present invention is defined by the appended claims. Without departing from the principles and essence of the present invention, those skilled in the art can make various changes or modifications to these embodiments, but these changes and modifications all fall within the protection scope of the present invention.
