Description

Technical Field

[0001] The utility model relates to the technical field of copper-aluminum joints, in particular to a copper-aluminum joint with a dustproof structure. Background Art

[0002] As we all know, my country is a country with relatively scarce copper resources and relatively abundant aluminum resources. For the air-conditioning industry, its refrigeration pipes mostly use copper. In order to reduce costs, it is feasible to use aluminum pipes on some pipe sections. However, since the melting point difference between copper pipes and aluminum pipes is about 400℃, copper-aluminum joints are often required at the joints between copper pipes and aluminum pipes to achieve pipe connections between different pipes.

[0003] However, when the existing copper-aluminum joints are not in use and need to be stored after leaving the factory, due to the poor dustproof effect, external dust particles can easily enter the inner wall of the copper-aluminum joints, causing wear on the inner wall of the copper-aluminum joints, thereby easily reducing the service life of the copper-aluminum joints.

[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

The body 1 includes a copper joint 2, an aluminum joint 3 and a fixed block 4. The copper joint 2 is connected to the aluminum joint 3 through the fixed block 4. The interior of the body 1 is through-connected. The sealing mechanism 5 includes a T-slot 6, a T-block 7, a connecting block 8, a connecting plate 9, a sealing block 10, a slide 11, a slider 12, a limit block 13, a through slot 14, a telescopic rod 15 and a damping block 16. The T-slot 6 is opened on the fixed block 4, one end of the T-block 7 extends into the T-slot 6, and the other end of the T-block 7 extends into the T-slot 6. One end is connected to one end of the connecting block 8, the other end of the connecting block 8 is connected to one end of the connecting plate 9, the other end of the connecting plate 9 is connected to one end of the sealing block 10, the sealing block 10 extends into the main body 1, the slide groove 11 is provided on the fixed block 4, one end of the slider 12 is slidably connected to the slide groove 11, the other end of the slider 12 is connected to one end of the limit block 13, the other end of the limit block 13 extends into the T-slot 6 and abuts against the T-block 7, the through groove 14 is provided on the T-block 7, and the sealing mechanism 5 is provided with two.

[0023] When in use, first pull the telescopic rod 15 so that the telescopic rod 15 drives the damping block 16 to separate from the fixed block 4. The damping block 16 has a damping effect and needs to be pulled hard.
