[0002] A refrigeration pipe is a tool for refrigerating by compressing air. Its working principle is to adjust the gas flow by adjusting the valve at the hot gas end, thereby controlling the temperature at the cold gas end. The refrigeration coefficient is the volume percentage of the cold air released at the cold gas end of the refrigeration pipe in the total volume of the input compressed air, and this coefficient can be adjusted as needed. The refrigeration pipe has the characteristics of reliable performance, safety, convenient installation and disassembly, and simple maintenance.
[0003] When installing the existing refrigeration pipes, it is usually necessary to connect them with bent pipes. Currently, when connecting refrigeration pipes, it is usually through welding. Although welding can achieve a good sealing effect for the refrigeration pipes, during welding, it is very easy to cause damage to the refrigeration pipes, and when there are certain problems with the welding, it is not convenient to disassemble the refrigeration pipes either.

[0023] The embodiments of the present invention will be described in detail below. The examples of the embodiments are shown in the drawings, where the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below by referring to the drawings are exemplary and are only used to explain the present invention and should not be construed as a limitation of the present invention.
[0024] Please refer to Figures 1-4 , a refrigeration pipe connecting device of the present invention includes a refrigeration pipe body 1 and an elbow pipe 11. The refrigeration pipe body 1 is the main body of the refrigeration pipe, and the elbow pipe 11 is the connecting structure of the refrigeration pipe. That is, the device connects the refrigeration pipe and the elbow pipe 11. There are two connecting sleeves 12 at the connection between the refrigeration pipe and the elbow pipe 11. The connecting sleeve 12 is the main body structure of the device and is used to connect the refrigeration pipe and the elbow pipe 11. A first connecting pipe 13 is arranged inside the front of the connecting sleeve 12, and a second connecting pipe 14 is arranged inside the rear of the connecting sleeve 12. By inserting the first connecting pipe 13 into the inside of the refrigeration pipe and the second connecting pipe 14 into the inside of the elbow pipe 11, the refrigeration pipe and the elbow pipe 11 are installed on both sides of the connecting sleeve 12, and the connecting sleeve 12 is sleeved outside the elbow pipe 11. Semi-circular sleeves 41 are arranged on the upper and lower sides in front of the connecting sleeve 12, and the semi-circular sleeves 41 are located outside the refrigeration pipe.
[0025] On one side of each of the two connecting sleeves 12, a connecting pipe 2 and a connecting rod 22 are respectively arranged. The connecting pipe 2 and the connecting rod 22 are in sliding connection. When the radius of the bent pipe 11 is enlarged, that is, the connecting pipe 2 slides on the connecting rod 22, so as to change the distance between the two connecting sleeves 12, and thus bent pipes 11 with different radii can be installed. On the upper and lower sides inside the connecting pipe 2, limiting rails 21 are arranged. On the upper and lower sides of the top of the connecting rod 22, limiting blocks 23 are arranged. The limiting blocks 23 and the limiting rails 21 are in sliding connection. That is, the limiting rails 21 limit the limiting blocks 23, so that the connecting rod 22 slides stably in the connecting pipe 2 and the connecting rod 22 is prevented from sliding out of the connecting pipe 2. On one side of the connecting pipe 2, a first screw thread 3 is arranged. Inside the first screw thread 3, a first bolt 33 is arranged. The first bolt 33 and the first screw thread 3 are in threaded connection. On the top of the first bolt 33, a clamping block 32 is arranged. On one side of the connecting rod 22, a plurality of clamping openings 31 are arranged. The clamping block 32 is disassembled and assembled on the clamping openings 31. After the distance between the two connecting sleeves 12 is adjusted, that is, the first bolt 33 is rotated on the first screw thread 3, so that the clamping block 32 is inserted into one of the clamping openings 31, and thus the two connecting sleeves 12 on both sides are fixed.
[0026] Sealing rings 4 are arranged on the front and rear sides of the connecting sleeve 12. The two sealing rings 4 are respectively attached to the refrigeration pipe and the bent pipe 11. Thus, when installing, the refrigeration pipe and the bent pipe 11 can achieve a sealing effect. On the bottom of the rear side of the connecting sleeve 12, a second screw thread 24 is arranged. Inside the second screw thread 24, a second bolt 34 is arranged. The second bolt 34 and the second screw thread 24 are in threaded connection. After the refrigeration pipe and the bent pipe 11 are installed, by rotating the second bolt 34 on the second screw thread 24, the second bolt 34 abuts against the bent pipe 11, so that the connection between the bent pipe 11 and the connecting sleeve 12 is more fixed. On the outer side of the semi-circular sleeve 41, a threaded strip 42 is arranged. The semi-circular sleeve 41 is relatively flexible. On the outer side of the threaded strip 42, a threaded sleeve 44 is arranged. The threaded sleeve 44 and the threaded strip 42 are in threaded connection. The threaded sleeve 44 is frustum-shaped, and the thread inside the threaded sleeve 44 is in a gradient form, that is, the radius inside the threaded sleeve 44 gradually becomes smaller. On the inner side of the semi-circular sleeve 41, an anti-slip rubber strip 43 is arranged. By rotating the threaded sleeve 44 on the threaded strip 42, the upper and lower semi-circular sleeves 41 are gradually pressed on the refrigeration pipe, and it is pressed and anti-slip through the anti-slip rubber strip 43, so that the refrigeration pipe is installed on the connecting sleeve 12, and vice versa for disassembly.
[0027] The working principle of the present utility model is as follows: When the device is in use, the first connecting pipe 13 is inserted into the interior of the refrigeration pipe, and the second connecting pipe 14 is inserted into the interior of the elbow pipe 11, so that the refrigeration pipe and the elbow pipe 11 are installed on both sides of the connecting sleeve 12, and the connecting sleeve 12 is sleeved on the outer side of the elbow pipe 11, and the semi-circular sleeve 41 is sleeved on the outer side of the refrigeration pipe. The sealing rings 4 on both sides are respectively attached to the refrigeration pipe and the elbow pipe 11. Thus, when installing, the refrigeration pipe and the elbow pipe 11 can achieve a sealing effect. By rotating the second bolt 34 in the second screw port 24, the second bolt 34 abuts against the elbow pipe 11, so that the connection between the elbow pipe 11 and the connecting sleeve 12 is more fixed. By rotating the threaded sleeve 44 on the threaded bar 42, the semi-circular sleeves 41 on the upper and lower sides are gradually pressed against the refrigeration pipe, and the anti-slip rubber strip 43 is used to press and prevent slipping, so that the refrigeration pipe is installed on the connecting sleeve 12. Conversely, for disassembly, by sliding the connecting pipe 2 on the connecting rod 22, and the limit rail 21 limits the limit block 23, the distance between the two connecting sleeves 12 is changed, and elbows 11 with different radii can be installed. When the distance between the two connecting sleeves 12 is adjusted, by rotating the first bolt 33 in the first screw port 3, the clamping block 32 is inserted into one of the clamping ports 31, that is, the two connecting sleeves 12 are fixed.
[0028] Although the embodiments of the present utility model have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present utility model. The scope of the present utility model is defined by the claims and their equivalents.
