Description

Technical Field

[0001] The utility model relates to the technical field of copper tubes for aircraft air conditioners, in particular to a connection structure for copper tubes for aircraft air conditioners. Background Art

[0002] Crane, overhead crane and crown crane are the common names for cranes. Overhead crane air conditioner is the air conditioner used on the crane, which is mainly used to cool the overhead crane cab so that the overhead crane operator does not have to work in a harsh environment and is used to improve the working environment. Moreover, the air-conditioning copper pipe is one of the important components of the overhead crane air conditioner, which is mainly responsible for transmitting the refrigerant and ensuring the normal circulation of the refrigerant in the air-conditioning system. During the laying of the air-conditioning copper pipe, in order to ensure the transmission of the refrigerant between different copper pipes, the air-conditioning copper pipes need to be connected through a connecting structure; in the prior art, when the air-conditioning copper pipes are connected, the position between the air-conditioning copper pipes is restricted by the cooperation of the copper nut and the connecting pipe, and the connection between the air-conditioning copper pipes is realized by plugging one connecting pipe with two air-conditioning copper pipes at the same time. However, during the use of some air-conditioning copper pipes, the pressure of the fluid flowing inside them is relatively high. Affected by the fluid pressure, it is easy to cause the sealing effect of the connecting parts to be reduced, and the probability of leakage at the connection gap of the air-conditioning copper pipe is relatively high.

The opposite inner end faces of the two connecting pipes are provided with a conical top ring, and a bellows is provided between the two conical top rings.

[0007] Furthermore, the connecting mechanism also includes a spring and a slip ring. The slip rings are respectively arranged on the outer arc surface of the connecting pipe. A spring is respectively provided between the two slip rings to limit the distance between the two connecting pipes.

[0008] Furthermore, the connecting mechanism also includes a cylinder, which is respectively arranged between the left and right inner walls of the sleeve.

DETAILED DESCRIPTION

[0020] 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.

[0021] See also Figure 1-4 ,This embodiment provides a technical solution: a connection structure of copper tubes for aircraft air conditioning, comprising a copper tube 1 and a connection mechanism 3;

[0022] Copper tubes 1: There are two and they are distributed on the left and right. The opposite inner end faces of the two copper tubes 1 are both provided with tapered rings 2 to facilitate the connection between the copper tubes 1 and the connecting mechanism 3. The outer arc surface of the copper tubes 1 is movably sleeved with copper nuts 4. When the connecting mechanism 3 and the copper nuts 4 are connected, the inner arc surface of the copper tubes 1 contacts the outer arc surface of the tapered rings 2, limiting the position of the copper tubes 1.

[0023] Connecting mechanism 3: It includes a connecting pipe 31, a conical insert ring 32, a conical top ring 33, a bellows 34 and a sleeve 35. The sleeve 35 is arranged between the two copper nuts 4. The left and right ends of the sleeve 35 are horizontally slidably connected with the connecting pipe 31. The outer arc end of the connecting pipe 31 is provided with a conical insert ring 32. The conical insert ring 32 is installed in conjunction with the conical ring 2. The opposite inner end faces of the two connecting pipes 31 are provided with a conical top ring 33. When the high-pressure fluid circulates in the copper pipe of the aircraft air conditioner, the pressure of the fluid is increased. The force will act on the inner arc surface of the conical top ring 33, pushing the two conical top rings 33 apart, making the conical insert ring 32 fit more closely with the conical ring 2, and improving the connection effect of the aircraft air-conditioning copper tube. A bellows 34 is provided between the two conical top rings 33 to seal the two conical top rings 33. The connecting mechanism 3 also includes a spring 37 and a slip ring 39. The slip rings 39 are respectively provided on the outer arc surface of the connecting tube 31. A spring 37 is provided between the two slip rings 39. Under the elastic force of the spring 37, The spacing between the two conical top rings 33 is limited so that the conical insert ring 32 fits tightly with the conical ring 2 to ensure the connection effect. The connecting mechanism 3 also includes a cylinder 36, which is respectively arranged between the left and right inner walls of the sleeve 35. The cylinder 36 passes through the circular hole on the surface of the slip ring 39 and the inside of the adjacent spring 37 to provide guide support for the expansion and contraction of the spring 37 and the sliding of the slip ring 39. The connecting mechanism 3 also includes an external threaded ring 38, which is respectively arranged at the left and right ends of the sleeve 35. The rings 38 are respectively threadedly connected to the adjacent copper nuts 4 to facilitate the connection between the sleeve 35 and the two copper nuts 4. The conical outer arc surface of the conical plug ring 32 is provided with a conical rubber pad 5 to seal the conical plug ring 32 and the conical ring 2. The left and right ends of the inner arc surface of the sleeve 35 are provided with annular rubber pads 6. The inner arc surface of the annular rubber pad 6 fits with the outer arc surface of the adjacent connecting pipe 31 to seal the sleeve 35 and the connecting pipe 31. The outer arc surface of the sleeve 35 is provided with a hexagonal ring 7 to facilitate the rotation of the sleeve 35.

[0024] The working principle of the connection structure of the copper tube of an aircraft air conditioner provided by the present utility model is as follows: when connecting the copper tube of the aircraft air conditioner, it is only necessary to limit the position between the sleeve 35 and the two copper tubes 1 through the threaded connection of the external threaded ring 38 and the copper nut 4. As the external threaded ring 38 and the copper nut 4 rotate relative to each other, the sleeve 35 and the copper tube 1 gradually approach each other. When the tapered plug ring 32 contacts the tapered ring 2, as the sleeve 35 and the copper tube 1 continue to approach each other, the elastic force of the spring 37 will be overcome, and the two connecting tubes 31 will be pushed closer to each other. Under the elastic force of the spring 37, the tapered plug ring 32 and the tapered ring 2 are tightly fitted to ensure the connection effect. When high-pressure fluid circulates in the copper tube of the aircraft air conditioner, the pressure of the fluid will act on the inner arc surface of the tapered top ring 33, pushing the two tapered top rings 33 apart relative to each other, making the tapered plug ring 32 fit more tightly with the tapered ring 2, thereby improving the connection effect of the copper tube of the aircraft air conditioner.

Any equivalent structure or equivalent process transformation made using the contents of the present invention specification and drawings, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
