Description

Technical Field

[0001] The utility model relates to the technical field of air conditioner copper tube connection structures, and specifically relates to a leak-proof sealing structure for air conditioner copper tube connection. Background Technique

[0002] Air conditioner copper tubes are pipes used to connect and transfer refrigerant, and they are usually made of copper. The main function of the copper tubes is to connect the evaporator, compressor and condenser to enable the refrigerant to circulate in the system. The connection between the copper tubes of the outdoor unit of the air conditioner and the pipeline is completed through matching bolts and nuts. Due to the strong vibration generated during the operation of the air conditioner, the vibration will cause the connection between the bolts and nuts to loosen, thus easily leading to leakage at the connection of the copper tubes. Therefore, the connection of the copper tubes needs to be sealed to prevent leakage.

[0003] For the existing copper tube sealing devices, waterproof tapes are mostly bundled or sealants are applied at the connection of the copper tubes. However, the waterproof tapes will age and break after long-term use. On the one hand, the sealant is prone to clogging the pipeline, and on the other hand, the sealant loses its activity after a long time, resulting in leakage still occurring at the connection of the copper tubes.

[0004] Therefore, the utility model provides a leak-proof sealing structure for air conditioner copper tube connection, and fixes the position of the fixing nut through the screw rod between the fixing piece and the fixing nut to solve the above problems. Content of the Utility Model

[0008] Preferably, the connecting component further includes a first sealing ring sleeved inside the threaded clamping pipe, and the first sealing ring is clamped at the port position of the T-shaped copper pipe body.

Specific implementation mode

[0022] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0023] Embodiment 1:

[0024] Please refer to Figures 1-6, A leak - proof sealing structure for the connection of air - conditioner copper pipes, including an air - conditioner outdoor unit 1. One side of the air - conditioner outdoor unit 1 is fixedly connected with a side plate 2. The outer end of the side plate 2 is fixedly connected with a T - shaped copper pipe body 3. The outer end of the T - shaped copper pipe body 3 is provided with a connection assembly 4. The connection assembly 4 includes a threaded clamping pipe 401 sleeved at the port position of the T - shaped copper pipe body 3. The outer end of the threaded clamping pipe 401 is threadedly connected with a fixing nut 403. The outer end of the T - shaped copper pipe body 3 is fixedly connected with a fixing piece 404. A screw rod 405 is threadedly connected between the fixing nut 403 and the fixing piece 404. A rotating connection pipe 402 is rotatably connected inside the threaded clamping pipe 401. One end of the rotating connection pipe 402 is threadedly connected with a connecting nut 406. The outer end of the connecting nut 406 is fixedly connected with a connecting pipe 407. Three groups of retaining plates are provided at the outer ends of both the fixing nut 403 and the fixing piece 404 and are arranged in a triangular shape. There are three screw rods 405. The inner ring of the fixing piece 404 is made of rubber material. The purpose of this setting is that when assembling the T - shaped copper pipe body 3 and the external pipeline, first, the fixing piece 404 is fixedly installed at the outer end of the T - shaped copper pipe body 3. Then, the threaded clamping pipe 401 is clamped at the port position of the T - shaped copper pipe body 3, and the fixing nut 403 is used to fix the threaded clamping pipe 401. After the threaded clamping pipe 401 is fixed at the port position of the T - shaped copper pipe body 3, the three screw rods 405 are threadedly connected in place between the retaining plates at the outer ends of the fixing nut 403 and the fixing piece 404. At the same time, the fixing piece 404 with a rubber - material inner ring increases the friction force between it and the T - shaped copper pipe body 3, preventing the T - shaped copper pipe body 3 from loosening from the fixing piece 404. This connection method makes it difficult for the connection between the fixing nut 403 and the T - shaped copper pipe body 3 to become loose when the T - shaped copper pipe body 3 vibrates, thus avoiding the leakage phenomenon at the connection of the T - shaped copper pipe body 3. At the same time, the deflection angle of the rotating connection pipe 402 can be freely adjusted, facilitating the installation of external pipelines at different positions.

[0025] Preferably, the connection assembly 4 further includes a first sealing ring 408 sleeved inside the threaded clamping pipe 401. The first sealing ring 408 is clamped at the port position of the T - shaped copper pipe body 3. The purpose of this setting is that the provided first sealing ring 408 enhances the sealing performance at the connection between the T - shaped copper pipe body 3 and the threaded clamping pipe 401.

[0026] Preferably, a clamping ring 5 is fixedly connected to the outer end of the rotating connection pipe 402. The connecting nut 406 is rotatably connected inside the clamping ring 5. A sealing gasket 6 is provided between the connecting nut 406 and the clamping ring 5. The purpose of this setting is that the provided sealing gasket 6 enhances the sealing performance at the connection between the clamping ring 5 and the connecting nut 406.

[0027] Embodiment Two:

[0028] Please refer to Figures 1-6, on the basis of the first embodiment, this embodiment provides a leak-proof sealing structure technical solution for the connection of air-conditioning copper pipes: special-shaped clamping plates 7 are symmetrically clamped at the outer ends of the snap ring 5 and the adapter nut 406. The two ends of the special-shaped clamping plate 7 are respectively clamped with the outer ends of the adapter pipe 402 and the connecting pipe 407. A screw 8 is threadedly connected between the two groups of special-shaped clamping plates 7. The purpose of this setting is that the special-shaped clamping plate 7 provided enhances the sealing performance between the snap ring 5 and the adapter nut 406, and prevents leakage at the connection between the adapter pipe 402 and the adapter nut 406.

[0029] Preferably, annular grooves are provided at both ends of the special-shaped clamping plate 7, and second sealing rings 9 are clamped inside the arc grooves. The two second sealing rings 9 are respectively sleeved on the outer ends of the adapter pipe 402 and the connecting pipe 407. The purpose of this setting is that the second sealing rings 9 provided enhance the sealing performance when the two groups of special-shaped clamping plates 7 are clamped, and prevent leakage at the connection between the T-shaped copper pipe body 3 and the connecting pipe 407.
