Description

Technical Field

[0001] The present invention relates to the technical field of wall-piercing bushing assemblies, and particularly relates to a wall-piercing bushing assembly for air conditioner installation. Background Art

[0002] During the use of an air conditioner, the air duct system of the indoor unit and the refrigeration system of the outdoor unit of the air conditioner are usually connected to each other by a conveying pipeline. The outdoor unit of the air conditioner is installed on the outer side of the wall. Therefore, the conveying pipeline between the outdoor unit and the indoor unit needs to pass through the wall. During the installation of the air conditioner, a hole needs to be drilled in the wall to place the bushing, and then the connecting lines such as the condensate water pipe, power line, and communication line between the indoor and outdoor units are passed through the wall and protected;

[0003] The inventor found that at least the following problems in the prior art have not been solved: 1. The bushing in the existing wall-piercing bushing assembly is often a hollow structure. Although it is convenient to insert pipelines, it lacks compressive resistance. During transportation, handling, or use, once it is deformed under pressure, it will cause compression to the pipelines, resulting in damage to the pipelines; 2. During the use of the existing wall-piercing bushing assembly, two bushings are often set, and the adjustment of the entire bushing length is carried out through threaded connection. However, the connection part of the two bushings lacks dust-proof measures, and it is easy for dust and the like to enter the connection part, resulting in unsmooth rotation adjustment. Therefore, we propose a wall-piercing bushing assembly for air conditioner installation. Summary of the Invention

[0004] The main purpose of the present invention is to provide a wall-piercing bushing assembly for air conditioner installation, which can effectively solve the problems in the background art.

[0005] To achieve the above purpose, the technical solution adopted by the present invention is as follows:

[0006] A wall-piercing bushing assembly for air conditioner installation, including a first bushing. The rear end of the first bushing is movably connected to a second bushing. A dust-proof device is fixedly connected to the front part of the outer surface of the second bushing. The dust-proof device is located between the first bushing and the second bushing. The rear end of the second bushing is fixedly connected to a first connection structure. The front end of the first bushing is fixedly connected to a second connection mechanism. The structure of the second connection mechanism is the same as that of the first connection structure. The diameter of the first bushing is smaller than that of the second bushing.

[0007] As a further improvement of the above solution, the dust-proof device includes a connection part. The front end of the connection part is fixedly connected to an extension part. A sealing ring is fixedly connected to the front part of the inner wall of the extension part.

[0008] As a further improvement of the above solution, the connection part is fixedly connected to the front part of the outer surface of the second bushing. The extension part is located on the outer surface of the first bushing. The sealing ring is in contact with the outer surface of the first bushing. There is no contact between the extension part and the first bushing.

[0009] By adopting the above technical solution: The connecting part is located on the outer surface of the second sleeve, and the extending part extends to the outer surface of the first sleeve. The extending part cooperates with the sealing ring to block the connecting gap between the first sleeve and the second sleeve, thereby preventing dust, sundries, etc. from entering the gap between the first sleeve and the second sleeve.

[0010] As a further improvement of the above solution, a first cavity penetrating through from front to back is opened at the front end of the first sleeve, and an external thread is provided at the rear part of the outer surface of the first sleeve.

[0011] As a further improvement of the above solution, a first inner tube is arranged inside the first sleeve. A first notch penetrating through from front to back is opened at the front end of the first inner tube, and six first support partition plates are fixedly connected to the outer surface of the first inner tube.

[0012] As a further improvement of the above solution, two of the six first support partition plates form a group. All six first support partition plates are of arc-shaped structures. The three groups of first support partition plates are annularly distributed at equal distances. One end of the six first support partition plates far away from the first inner tube is fixedly connected to the first sleeve.

[0013] As a further improvement of the above solution, a second cavity penetrating through from front to back is opened at the front end of the second sleeve, and an internal thread is provided at the front part of the inner wall of the second cavity.

[0014] As a further improvement of the above solution, a second inner tube is arranged inside the second sleeve. A second notch penetrating through from front to back is opened inside the second inner tube. Six second support partition plates are fixedly connected to the outer surface of the second inner tube. Two of the six second support partition plates form a group. The three groups of second support partition plates are annularly and equally spaced. All six second support partition plates are of arc-shaped structures. All six second support partition plates are inserted and slidably connected to the second sleeve. The second sleeve is threadedly connected to the first sleeve through the internal thread.

[0015] By adopting the above technical solution: The first inner tube inside the first sleeve cooperates with several first support partition plates to support the first sleeve, preventing the first sleeve from deforming after being compressed. The several second support partition plates inside the second sleeve cooperate with the second inner tube to support the second sleeve, preventing the second sleeve from deforming after being compressed. Since the second inner tube and several second support partition plates are inserted into the second sleeve, it is convenient for the pipeline to penetrate into the first sleeve and then into the second sleeve.

[0016] As a further improvement of the above solution, the second connecting mechanism includes a connecting plate. Four protruding parts are fixedly connected to the outer surface of the connecting plate. The four protruding parts are evenly distributed in a ring at equal distances. Installation holes penetrating through the front and back are opened at the front ends of the four protruding parts. Four clamping parts are fixedly connected to the front end of the connecting plate. A tightening strap is inserted and movably connected to the four clamping parts together.

[0017] As a further improvement of the above solution, the four clamping parts are all of a structure that is narrow in the front and wide in the rear. Limiting grooves are opened on the outer surfaces of the four clamping parts. The connecting plate is fixedly connected to the first sleeve.

[0018] By adopting the above technical solution: the pipeline passes through the connecting plate and then penetrates into the first sleeve. The tightening strap is wound around the four clamping parts at the same time. The tightening strap is tightened, so that the tightening strap clamps the four clamping parts. After the four clamping parts are deformed, the pipeline is clamped at the same time, avoiding the shaking and displacement of the pipeline.

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] 1. In the present invention, by setting a dust-proof device, since the connecting part is fixedly connected to the outer surface of the second sleeve, the extending part at the front end of the connecting part is located at the connecting part of the first sleeve and the second sleeve. Since a sealing ring is fixedly connected in the extending part and the sealing ring contacts the outer surface of the first sleeve, dust and other sundries can be avoided from entering the connecting part of the first sleeve and the second sleeve during use, thereby improving the smoothness of adjustment.

[0021] 2. In the present invention, by arranging a first inner tube in the first sleeve, and six first support partitions are fixed on the outer surface of the first inner tube. The six first support partitions cooperate with the first inner tube to support the inner wall of the first sleeve, improving the strength of the first sleeve and avoiding the deformation of the first sleeve. By arranging a second inner tube in the second sleeve, and six second support partitions are fixed on the outer surface of the second inner tube. The six second support partitions cooperate with the second inner tube to support the second sleeve, so that the second sleeve can be prevented from deforming and pressing the pipeline. Since the second inner tube and the six second support partitions are inserted into the second sleeve, they can be flexibly removed and inserted.

[0022] 3. In the present invention, by setting a second connecting mechanism, four clamping parts evenly distributed are fixedly connected to the front end of the connecting plate. The tightening strap is clamped into the limiting grooves opened on the four clamping parts. The tightening strap is tightened, so that the tightening strap tightens the clamping parts at the same time, thereby restraining and limiting the pipeline inserted into the connecting plate and avoiding the shaking of the pipeline.

[0037] As Figure 1-8 shown, a wall-piercing sleeve assembly for air conditioner installation includes a first sleeve 1. The rear end of the first sleeve 1 is movably connected to a second sleeve 3. A dust-proof device 2 is fixedly connected to the front part of the outer surface of the second sleeve 3. The dust-proof device 2 is located between the first sleeve 1 and the second sleeve 3. The rear end of the second sleeve 3 is fixedly connected to a first connection structure 4. The front end of the first sleeve 1 is fixedly connected to a second connection mechanism 5. The structure of the second connection mechanism 5 is the same as that of the first connection structure 4. The diameter of the first sleeve 1 is smaller than that of the second sleeve 3.

[0038] The dust-proof device 2 includes a connecting part 21. The front end of the connecting part 21 is fixedly connected to an extending part 23. A sealing ring 22 is fixedly connected to the front part of the inner wall of the extending part 23. The connecting part 21 is fixedly connected to the front part of the outer surface of the second sleeve 3. The extending part 23 is located on the outer surface of the first sleeve 1. The sealing ring 22 is in contact with the outer surface of the first sleeve 1. There is no contact between the extending part 23 and the first sleeve 1.

[0039] Through the above solution: The connecting part 21 is located on the outer surface of the second sleeve 3. The extending part 23 extends to the outer surface of the first sleeve 1. The extending part 23 cooperates with the sealing ring 22 to block the connection gap between the first sleeve 1 and the second sleeve 3, thereby preventing dust, sundries, etc. from entering the gap between the first sleeve 1 and the second sleeve 3.

[0040] The front end of the first sleeve 1 is provided with a first cavity 12 that penetrates through from front to back, and an external thread 11 is arranged at the rear part of the outer surface of the first sleeve 1; a first inner tube 13 is arranged inside the first sleeve 1, the front end of the first inner tube 13 is provided with a first notch 15 that penetrates through from front to back, and six first support partitions 14 are fixedly connected to the outer surface of the first inner tube 13; two of the six first support partitions 14 form a group, the six first support partitions 14 are all arc-shaped structures, the three groups of first support partitions 14 are annularly distributed at equal distances, and one end of the six first support partitions 14 far from the first inner tube 13 is fixedly connected to the first sleeve 1; the front end of the second sleeve 3 is provided with a second cavity 31 that penetrates through from front to back, and an internal thread 32 is arranged at the front part of the inner wall of the second cavity 31; a second inner tube 34 is arranged inside the second sleeve 3, a second notch 35 that penetrates through from front to back is formed inside the second inner tube 34, and six second support partitions 33 are fixedly connected to the outer surface of the second inner tube 34, two of the six second support partitions 33 form a group, the three groups of second support partitions 33 are annularly and equidistantly distributed, the six second support partitions 33 are all arc-shaped structures, the six second support partitions 33 are all inserted and slidably connected with the second sleeve 3, and the second sleeve 3 is threadedly connected with the first sleeve 1 through the internal thread 32.

[0041] Through the above solution: the first inner tube 13 inside the first sleeve 1 cooperates with several first support partitions 14 to support the first sleeve 1, avoiding deformation of the first sleeve 1 after being pressed, and several second support partitions 33 inside the second sleeve 3 cooperate with the second inner tube 34 to support the second sleeve 3, avoiding deformation of the second sleeve 3 after being pressed. Since the second inner tube 34 and several second support partitions 33 are inserted into the second sleeve 3, it is convenient for the pipeline to penetrate into the first sleeve 1 and then into the second sleeve 3.

[0042] The second connection mechanism 5 includes a connecting plate 51, four protruding parts 53 are fixedly connected to the outer surface of the connecting plate 51, the four protruding parts 53 are annularly and equidistantly distributed, mounting holes 55 that penetrate through from front to back are formed at the front ends of the four protruding parts 53, four clamping parts 54 are fixedly connected to the front end of the connecting plate 51, and a tightening strap 52 is jointly inserted and movably connected to the four clamping parts 54; the four clamping parts 54 are all structures that are narrow in the front and wide in the back, limiting grooves 541 are formed on the outer surfaces of the four clamping parts 54, and the connecting plate 51 is fixedly connected to the first sleeve 1.

[0043] Through the above solution: the pipeline passes through the connecting plate 51 and then penetrates into the first sleeve 1. The tightening strap 52 is wound around the four clamping parts 54 at the same time, and the tightening strap 52 is tightened, so that the tightening strap 52 clamps the four clamping parts 54. After the four clamping parts 54 are deformed, the pipeline is clamped at the same time, avoiding the shaking and displacement of the pipeline.

[0044] In summary, during the use of the present invention, first, the first sleeve 1 and the second sleeve 3 are aligned from both sides of the wall and respectively inserted into the reserved holes in the wall. The length adjustment between the first sleeve 1 and the second sleeve 3 is achieved through a threaded connection method, which facilitates flexible adjustment of the total length of the sleeve according to actual installation requirements. During the adjustment process, the connecting part 21 is fixedly connected and closely combined with the outer surface of the second sleeve 3 to ensure that there is no loosening or dislocation during adjustment. The extension part 23 at the front end of the connecting part 21 forms an effective protective barrier in the connection area between the first sleeve 1 and the second sleeve 3. The sealing ring 22 fixedly installed inside the extension part 23 ensures a tight fit with the outer surface of the first sleeve 1, effectively blocking dust and other sundries from entering the connecting part, thus maintaining the smooth operation of the adjustment and extending the service life of the sleeve. To further enhance the structural strength and stability of the sleeve, a first inner tube 13 is configured inside the first sleeve 1, and six first support partition plates 14 are uniformly fixed on its outer surface. These support partition plates work together with the first inner tube 13 to provide solid internal support for the first sleeve 1, effectively preventing the sleeve from deforming due to external forces and ensuring the safety and smoothness of the pipeline passing through. Similarly, a second inner tube 34 and six matching second support partition plates 33 are provided inside the second sleeve 3. Such a double support structure enables the second sleeve 3 to also have excellent anti-deformation ability, avoiding unnecessary crushing or damage to the pipeline due to sleeve deformation. The support partition plates 33 can be easily taken out or put into the second sleeve 3, improving the flexibility of use. After the pipeline is successfully inserted into the first sleeve 1 and the second sleeve 3, to ensure the stability and safety of the pipeline, since there are four clamping parts 54 uniformly distributed at the front end of the connecting plate 51, and a limiting groove 541 is opened on each clamping part, by tightening the tightening strap 52, the four clamping parts 54 are synchronously tightened, thereby achieving a firm restraint and limitation on the pipeline inserted into the connecting plate 51, effectively reducing the shaking of the pipeline during use and enhancing the stability and safety of the entire installation system.
