Description

Technical Field

[0001] This utility model relates to the field of exhaust pipe technology, and in particular to an exhaust pipe for refrigeration equipment. Background Technology

[0002] The exhaust pipe of refrigeration equipment is a pipeline component used to transport high-temperature and high-pressure refrigerant gas from the compressor to the condenser. It is usually made of high-pressure resistant and corrosion-resistant copper or steel pipes.

[0003] Existing technologies, such as the utility model patent with publication number CN222732337U, disclose an exhaust pipe for a refrigeration device. The key technical points are: it includes a first pipe and a second pipe, with a connecting pipe between them; first annular grooves are formed at the ends of the first and second pipes that are close to each other, and first annular sealing gaskets are placed in the grooves; the two ends of the connecting pipe are sequentially and tightly fitted to the ends of the first and second pipes. The key feature is that the outer circumferences of the ends of the first and second pipes that are close to each other are respectively threaded, and internally threaded pipes are threadedly installed in these grooves. Several sliders are fixedly installed on the inner circumference of the internally threaded pipes. First annular grooves are formed on the outer circumferences of the connecting pipes corresponding to the sliders, and the sliders are slidably installed in the corresponding first annular grooves. Even after the first and second pipes are installed, the connecting pipe can still be removed between them for easy disassembly, meeting market demands and making it suitable for widespread application.

[0004] Regarding the above-mentioned issues, the following technical defects have been found: In the existing technology, when the exhaust pipe of the refrigeration equipment is in use, because the structure of the exhaust pipe is relatively fixed, the personnel cannot adjust the exhaust direction of the exhaust pipe, and therefore cannot adjust the exhaust direction according to the space limitations of the installation site. This can easily lead to interference between the pipe and other components, and can also easily cause the discharged high-temperature exhaust gas to be re-inhaled by the equipment. Utility Model Content

[0005] The purpose of this utility model is to solve the problem that in the existing technology, the exhaust pipe of refrigeration equipment cannot be adjusted by personnel because the structure of the exhaust pipe is relatively fixed. Therefore, this utility model proposes an exhaust pipe for refrigeration equipment.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a refrigeration equipment exhaust pipe, comprising a refrigeration body, a connecting pipe, and an adjusting structure. The connecting pipe is fixedly connected to one side of the refrigeration body, and the adjusting structure is located on the connecting pipe. The adjusting structure includes a support plate, which is fixed to the outer wall of the connecting pipe. An arc-shaped shell is fixedly connected to the upper surface of the support plate. The cross-section of the arc-shaped shell is greater than half a semicircle. A ball bearing is movably connected to the inner wall of the arc-shaped shell. A pressure rod is threaded through the outer wall of the arc-shaped shell. A lead screw is rotatably connected to the arc surface of the ball bearing. An ear plate is threaded to the arc surface of the lead screw. An exhaust pipe is fixedly connected to one side of the ear plate. A corrugated pipe is fixedly connected to the exhaust pipe and the connecting pipe close to each other.

[0007] The effect achieved by the above components is as follows: by setting the adjustment structure, the exhaust direction of the refrigeration equipment exhaust pipe can be easily adjusted during use, so as to adjust the exhaust direction according to the space constraints of the installation site, avoid interference between the pipe and other components, and prevent the exhaust high-temperature exhaust gas from being re-inhaled by the equipment by adjusting the direction.

[0008] Preferably, a guide rod is slidably provided on the side of the ear plate, and one end of the guide rod is fixedly connected to the arc surface of the ball.

[0009] The effect achieved by the above components is that when the lead screw drives the ear plate to move, the guide rod can guide and position the ear plate, thereby preventing rotational deviation during the movement of the ear plate.

[0010] Preferably, one end of the pressure rod is fixedly connected to a rubber pad, and one side of the rubber pad abuts against the arc surface of the ball.

[0011] The effect achieved by the above components is that the rubber pad can increase the friction at the end of the pressure rod near the ball, thereby improving the limiting effect of the pressure rod on the ball.

[0012] Preferably, a plurality of rotating plates are fixedly connected to one end of the lead screw, and the rotating plates are evenly distributed at one end of the lead screw.

[0013] The effect achieved by the above components is that rotating the rotating plate can drive the lead screw to rotate, thus achieving the effect of conveniently controlling the rotation of the lead screw.

[0015] The effect achieved by the above components is that, by setting up an auxiliary structure, when the refrigeration equipment is not in use, the sealing cover can be easily adjusted to seal the exhaust port of the exhaust pipe, thereby preventing external dust and other dirt from entering the interior of the refrigeration unit through the exhaust pipe.

[0016] Preferably, a positioning rod is slidably inserted through the arc surface of the slide rod, the positioning rod is fixed to the inner wall of the slide hole, and a coil spring is sleeved on the arc surface of the positioning rod, with both ends of the coil spring being fixedly connected to the slide hole and the slide rod, respectively.

[0017] The effect achieved by the above components is that after the rotating adjusting ring separates from the fixed seat, the coil spring can drive the sealing cover to move quickly away from the exhaust pipe, thus achieving the effect of quickly opening the sealing cover.

[0018] Preferably, a handle is fixedly connected to the arc surface of the sealing cap, and the handle has a "U" shaped cross-section.

[0019] The effect achieved by the above components is that the moving handle can drive the sealing cover, thus achieving the effect of convenient control of the sealing cover.

[0020] In summary, the beneficial effects of this utility model are as follows:

[0021] In this utility model, by setting an adjustment structure, the exhaust direction of the refrigeration equipment exhaust pipe can be easily adjusted during use. This allows the exhaust direction to be adjusted according to the space limitations of the installation site, avoiding interference between the pipe and other components. Furthermore, by adjusting the direction, the high-temperature exhaust gas can be prevented from being re-inhaled by the equipment.

[0022] In this invention, by setting an auxiliary structure, when the refrigeration equipment is not in use, the sealing cover can be easily adjusted to seal the exhaust port of the exhaust pipe, thereby preventing external dust and other dirt from entering the interior of the refrigeration unit through the exhaust pipe.

It should be understood that these embodiments are for illustrative purposes only and are not intended to limit the scope of the present invention. Furthermore, it should be understood that after reading the teachings of this invention, those skilled in the art can make various alterations or modifications to the present invention, and these equivalent forms also fall within the scope defined by the appended claims.

[0030] Reference Figure 1 As shown, this utility model provides a technical solution: a refrigeration equipment exhaust pipe, including a refrigeration body 1, a connecting pipe 2 and an adjustment structure 3, wherein the connecting pipe 2 is fixedly connected to one side of the refrigeration body 1.

[0031] Among them, the adjustment structure 3 is located on the connecting pipe 2, and the outer wall of the exhaust pipe 306 is provided with an auxiliary structure 4.

[0032] The specific settings and functions of its adjustment structure 3 and auxiliary structure 4 will be discussed below.

[0033] Reference Figure 2 and Figure 3As shown in this embodiment: the adjustment structure 3 includes a support plate 301, which is fixed to the outer wall of the connecting pipe 2. An arc-shaped shell 311 is fixedly connected to the upper surface of the support plate 301. The cross-section of the arc-shaped shell 311 is greater than half a semicircle. A ball bearing 302 is movably connected to the inner wall of the arc-shaped shell 311. A pressure rod 303 is threaded through the outer wall of the arc-shaped shell 311. A lead screw 304 is rotatably connected to the arc surface of the ball bearing 302. An ear plate 305 is threaded to the arc surface of the lead screw 304. An exhaust pipe 306 is fixedly connected to one side of the ear plate 305. A corrugated pipe 307 is fixedly connected to the exhaust pipe 306 and the connecting pipe 2, close to each other. By setting the adjustment structure 3, the exhaust direction of the refrigeration equipment exhaust pipe 306 can be easily adjusted during use. This allows for adjustment of the exhaust direction according to the space limitations of the installation site, avoiding interference between the pipe and other components. Furthermore, by adjusting the direction, it can prevent the discharged high-temperature exhaust gas from being re-inhaled by the equipment. A guide rod 309 is slidably inserted through the side of the ear plate 305, and one end of the guide rod 309 is fixedly connected to the arc surface of the ball 302. When the lead screw 304 drives the ear plate 305 to move, the guide rod 309 can guide and position the ear plate 305, thereby preventing rotational deviation during the movement of the ear plate 305. A rubber pad 310 is fixedly connected to one end of the pressure rod 303, and one side of the rubber pad 310 abuts against the arc surface of the ball 302. The rubber pad 310 can increase the friction of the end of the pressure rod 303 near the ball 302, thereby improving the limiting effect of the pressure rod 303 on the ball 302. Several rotating plates 308 are fixedly connected to one end of the lead screw 304, and the rotating plates 308 are evenly distributed at one end of the lead screw 304. Rotating the rotating plates 308 can drive the lead screw 304 to rotate, achieving the effect of conveniently controlling the rotation of the lead screw 304.

[0034] Reference Figure 4 and Figure 5As shown in this embodiment: the auxiliary structure 4 includes a fixed base 401, which is fixedly connected to the outer wall of the exhaust pipe 306. A connecting plate 402 is rotatably connected to the inner wall of the fixed base 401. A sealing cover 403 is fixedly connected to one side of the connecting plate 402. A sliding hole 405 is provided on one side of the fixed base 401. The cross-section of the sliding hole 405 is arc-shaped, and the center of the sliding hole 405 is coaxial with the axis of rotation of the connecting plate 402. A sliding rod 406 is slidably connected to the inner wall of the sliding hole 405. An adjusting ring 407 is threadedly connected to the arc surface of the sliding rod 406. One side of the adjusting ring 407 abuts against the fixed base 401. By setting the auxiliary structure 4, when the refrigeration equipment is not in use, the sealing cover 403 can be easily adjusted to seal the outlet of the exhaust pipe 306, thereby preventing external dust and other dirt from entering the interior of the refrigeration unit 1 through the exhaust pipe 306. A positioning rod 408 slides through the arc surface of the slide rod 406. The positioning rod 408 is fixed to the inner wall of the slide hole 405. A coil spring 409 is sleeved on the arc surface of the positioning rod 408, and both ends of the coil spring 409 are fixedly connected to the slide hole 405 and the slide rod 406, respectively. After the rotating adjusting ring 407 separates from the fixed seat 401, the coil spring 409 can drive the sealing cover 403 to move quickly away from the exhaust pipe 306, achieving the effect of quickly opening the sealing cover 403. A handle 404 is fixedly connected to the arc surface of the sealing cover 403. The cross-section of the handle 404 is "U". Moving the handle 404 can drive the sealing cover 403, achieving the effect of conveniently controlling the sealing cover 403.

[0035] Detailed Instructions for Use: When adjusting the exhaust direction of exhaust pipe 306, first rotate the rotating plate 308 to drive the lead screw 304 to rotate. The lead screw 304 drives the ear plate 305, causing the ear plate 305 to move along the arc surface of the lead screw 304 under the guidance of the guide rod 309. The ear plate 305 drives the exhaust pipe 306 to move horizontally. The bellows 307 can connect the connecting pipe 2 to the exhaust pipe 306. When the exhaust pipe 306 has moved to the appropriate position, stop rotating the lead screw 304. Then rotate the pressure rod 303 to separate the rubber pad 310 from the ball bearing 302, releasing the limit on the ball bearing 302. Then rotate the exhaust pipe 306. During the rotation of the exhaust pipe 306, the ball bearing 302 will move along the inside of the arc shell 311. When the exhaust pipe 306 rotates to the appropriate position, the pressure rod 303 is rotated to drive the rubber pad 310 to abut against the arc surface of the ball bearing 302, thereby locking the exhaust pipe 306. When the screw 304 is rotated to drive the ear plate 305 to move, the guide rod 309 can guide and position the ear plate 305, thereby preventing the ear plate 305 from rotating and deviating during its movement. In addition, the rubber pad 310 can increase the friction of the pressure rod 303 near the end of the ball bearing 302, thereby improving the limiting effect of the pressure rod 303 on the ball bearing 302.

[0036] When the refrigeration equipment is not in use and the exhaust pipe 306 needs to be sealed, first move the handle 404 to rotate the sealing cover 403. During the rotation of the sealing cover 403, the connecting plate 402 will rotate along the inner wall of the fixed base 401. At the same time, the slide rod 406 fixed on the connecting plate 402 will slide along the inner wall of the sliding hole 405. After the sealing cover 403 blocks the outlet of the exhaust pipe 306, rotate the adjusting ring 407 to abut against the fixed base 401 to lock the sealing cover 403 and seal the exhaust pipe 306. When it is necessary to open the sealing cover 403 to use the refrigeration equipment, first rotate the adjusting ring 407 to separate it from the fixed base 401 and release the lock on the slide rod 406. At this time, the coil spring 409 can drive the sealing cover 403 to move quickly away from the exhaust pipe 306, achieving the effect of quickly opening the sealing cover 403.
