[0026] The exhaust pipe is a part of the refrigeration equipment. The exhaust pipe discharges the gas in the refrigeration equipment to the outside. The existing exhaust pipe uses a fixed ring to connect the two exhaust pipes during use, so that the exhaust pipe can be easily replaced when a failure occurs. The fixed ring uses bolts and nuts to fix the two exhaust pipes during the process of fixing the exhaust pipe. Although it has a good fixing effect, the bolts are small in size during installation and are not convenient to take and fix during installation. For some high-altitude installation environments, the installer may need to hold the bolts while fixing them with the help of fixing equipment. The fixing method is more troublesome.

[0027] like Figures 1 to 4As shown, the utility model provides an exhaust pipe for refrigeration equipment, including: a first exhaust pipe 1 and a second exhaust pipe 2, a connecting component 3 for convenient plugging of the first exhaust pipe 1 and the second exhaust pipe 2 and a limiting component 4 for fixing the first exhaust pipe 1 and the second exhaust pipe 2 are arranged between the first exhaust pipe 1 and the second exhaust pipe 2, the connecting component 3 includes a connecting protrusion 301 connected to one side of the second exhaust pipe 2 and a limiting slot 302 opened in the first exhaust pipe 1, the connecting protrusion 301 and the limiting slot 302 are adapted to each other, the connecting protrusion 301 is plugged into the limiting slot 302, the limiting component 4 includes a first fixing ring 401 and a second fixing ring 402 used in conjunction with the first fixing ring 401, the first fixing ring 401 and the second fixing ring 402 are used in conjunction with each other to form a closed ring, the first fixing ring 401 is connected to a mounting block 403, one end of the mounting block 403 is plugged into the second fixing ring 402, and the second fixing ring 402 is opened There is a cavity for the connection of the mounting block 403, and a limit block 404 is slidably provided in the second fixing ring 402 for clamping the mounting block 403. In order to facilitate the limit block 404 to limit the mounting block 403, chamfers can be set on the mounting block 403 and the limit block 404, so that the mounting block 403 can push the limit block 404 to move due to the chamfer during the plug-in process, thereby facilitating the positioning of the first fixing ring 401 and the second fixing ring 402. One side of the limit block 404 is connected with a connecting Connecting rod 405, one end of connecting rod 405 extends to the outside of the second fixing ring 402. In order to facilitate the force to pull the connecting rod 405 to move horizontally, one end of connecting rod 405 extends to the outside of the second fixing ring 402 and is connected to a force plate 8. An anti-slip sleeve is sleeved on the force plate 8, and the anti-slip sleeve has anti-slip patterns integrally formed thereon. A compression spring 406 is sleeved on the connecting rod 405, and one end of the compression spring 406 is connected to the limit block 404, and the other end is connected to the second fixing ring 402.

[0028] By inserting the connecting protrusion 301 connected to one side of the second exhaust pipe 2 into the limiting slot 302 opened on one side of the first exhaust pipe 1, it is convenient to perform a preliminary fixed connection between the first exhaust pipe 1 and the second exhaust pipe 2, and then the first fixing ring 401 and the second fixing ring 402 are clamped at the connection between the first exhaust pipe 1 and the second exhaust pipe 2. During the clamping process of the first fixing ring 401 and the second fixing ring 402, the mounting block 403 connected to the first fixing ring 401 can be inserted into the second fixing ring 402. During the insertion of the second fixing ring 402, the mounting block 403 can push the limiting block 404 to move horizontally. When the limiting block 404 moves to no longer contact the mounting block 403, the limiting block 404 is clamped on the mounting block 403 by the elastic force of the compression spring 406 to limit the mounting block 403. The first exhaust pipe 1 and the second exhaust pipe 2 can be quickly connected by using the provided connecting component 3 and the limiting component 4. Compared with the fixing direction of bolts and nuts in the prior art, the fixing efficiency is higher and the operation is more convenient.

[0029] For details, please continue to refer to Figure 4 A telescopic spring 5 is connected inside the second fixing ring 402, and the other end of the telescopic spring 5 is connected to a push plate 6. The position of the push plate 6 corresponds to the mounting block 403. The telescopic spring 5 and the push plate 6 can be used together. When the limit block 404 no longer conflicts with the mounting block 403, the elastic force of the telescopic spring 5 can push the push plate 6 to move vertically upward, and then push the mounting block 403 to move upward, which is convenient for releasing the first fixing ring 401 and the second fixing ring 402 from the first exhaust pipe 1 and the second exhaust pipe 2, and facilitating the disassembly and maintenance of the first exhaust pipe 1 and the second exhaust pipe 2.

[0030] For details, please refer to Figure 4 A guide block 7 is connected to one side of the limit block 404, and the other end of the guide block 7 is slidably connected to the second fixed ring 402. A connecting groove adapted to the guide block 7 is provided in the second fixed ring 402. This setting can limit and guide the sliding of the limit block 404, further improving the stability of the limit block 404 during the sliding process.

[0031] For details, please refer to Figure 4 In order to avoid the situation where the connecting rod 405 may not move accidentally due to insufficient elastic force of the compression spring 406, a rotating block 9 is rotatably connected to one side of the second fixed ring 402, and a positioning groove 10 adapted to the rotating block 9 is opened on the force plate 8. Anti-slip particles are integrally formed in the positioning groove 10. When the limit block 404 has completed the positioning of the mounting block 403, the rotating block 9 is rotated so that the rotating block 9 is inserted into the positioning groove 10 to restrain the movement of the connecting rod 405, thereby avoiding the situation where the connecting rod 405 may move accidentally, and the anti-slip particles increase the friction.

[0032] Working principle: When the first exhaust pipe 1 and the second exhaust pipe 2 fail and need to be replaced:

[0033] By inserting the connecting protrusion 301 connected to one side of the second exhaust pipe 2 into the limiting slot 302 opened on one side of the first exhaust pipe 1, it is convenient to perform a preliminary fixed connection between the first exhaust pipe 1 and the second exhaust pipe 2, and then the first fixing ring 401 and the second fixing ring 402 are clamped at the connection between the first exhaust pipe 1 and the second exhaust pipe 2. During the clamping process of the first fixing ring 401 and the second fixing ring 402, the mounting block 403 connected to the first fixing ring 401 can be inserted into the second fixing ring 402. During the insertion of the second fixing ring 402, the mounting block 403 can push the limiting block 404 to move horizontally. When the limiting block 404 moves to no longer contact the mounting block 403, the limiting block 404 is clamped on the mounting block 403 by the elastic force of the compression spring 406 to limit the mounting block 403. The first exhaust pipe 1 and the second exhaust pipe 2 can be quickly connected by using the provided connecting component 3 and the limiting component 4. Compared with the fixing direction of bolts and nuts in the prior art, the fixing efficiency is higher and the operation is more convenient.
