Description

Technical Field

[0001] This utility model relates to the field of refrigeration equipment technology, and in particular to a refrigerant diversion device for cold storage refrigeration equipment. Background Technology

[0002] With increasing awareness of environmental protection, cold storage refrigeration systems are placing greater emphasis on the environmental friendliness of refrigerants. Traditional refrigerants, such as Freon, are gradually being replaced by environmentally friendly refrigerants. This requires refrigerant distribution devices to be able to adapt to different types of refrigerants, ensuring that the equipment can still maintain efficient distribution and control capabilities when using environmentally friendly refrigerants. Therefore, refrigerant distribution devices must not only meet the requirements of efficient and precise distribution, but also have good adaptability and be compatible with a variety of environmentally friendly refrigerants.

[0003] Existing technologies, such as the utility model patent with publication number CN216557794U, disclose a refrigerant distribution device for cold storage refrigeration equipment. This patent includes an upper connecting pipe that communicates with a distribution cylinder. A lower base is snapped into the lower side of the distribution cylinder, and a side fixing ring is provided on the upper side of the lower base. The outer wall of the side fixing ring is in contact with the inner wall of the distribution cylinder. A fixing structure is provided on the outer side of the distribution cylinder, passing through the distribution cylinder and engaging with a recessed hole on the side fixing ring. When the side fixing ring on the upper side of the lower base extends into the distribution cylinder, its surface directly acts on the engaging pyramid. This engaging pyramid causes a moving column to extend into the fixed cylinder, compressing and deforming a return spring. After the side fixing ring is engaged in the appropriate position, under the action of the return spring, the moving column drives the engaging column to extend out of the fixed cylinder, thus engaging the engaging pyramid with the recessed hole on the side fixing ring. This makes the fixing of the distribution cylinder and the lower base more convenient and quick.

[0004] The inventors discovered in daily use that existing shunt devices are usually integrated units, with a few parts fixed by screws. However, using screws for fixing is cumbersome and time-consuming, which greatly reduces the efficiency of shunt device maintenance.

[0005] This application provides another technical solution to this technical problem, aiming to provide those skilled in the art with multiple options for solving the problem. Utility Model Content

[0006] The purpose of this utility model is to address the shortcomings of existing technologies where refrigerant distribution devices are typically integrated units with a few parts fixed by screws. However, using screws for fixing is cumbersome and time-consuming, greatly reducing the efficiency of maintenance and repair of the refrigerant distribution device.

[0008] The effect achieved by the above components is that the diverter and base can be easily and quickly fixed and installed by setting the adjustment structure, so that personnel can inspect and maintain the inside, greatly increasing its service life and avoiding the cumbersome and time-consuming installation by using screws.

[0009] Preferably, the arc surface of the rotating ring is provided with anti-slip texture, and the anti-slip texture is evenly distributed on the rotating ring.

[0010] The effect achieved by the above components is that the anti-slip texture increases the friction of the rotating ring, preventing the hands from slipping when the ring is rotated.

[0014] The effect achieved by the above components is that the ball bearings can reduce the friction of the connecting block, making the connecting block move more smoothly in the groove.

[0015] Preferably, a pulley is rotatably connected to one side of the fixed block, and the arc surface of the pulley is slidably connected to the push block.

[0016] The effect achieved by the above components is that the pulley can reduce the friction between the fixed block and the push block, thereby allowing the fixed block to move better.

[0017] Preferably, the arc surface of the spring is fitted with a bellows, and the two ends of the bellows are fixedly connected to the diverter and the positioning block, respectively.

[0018] The effect achieved by the above components is that the bellows can protect the spring and prevent foreign objects from getting stuck in the spring and affecting its use.

[0019] Preferably, a guide block is fixedly connected to the other side of the fixing block.

[0020] The effect achieved by the above components is that, due to the small size of the guide block, the fixing block can be better inserted into the interior of the connecting block.

[0021] In summary, the beneficial effects of this utility model are as follows:

[0022] In this invention, by setting an adjustment structure, the diverter cylinder can be conveniently and quickly fixedly installed to the base, thereby facilitating internal inspection and maintenance by staff, significantly extending the service life of the equipment, and avoiding the cumbersome process of fixing with screws, improving installation efficiency and reducing maintenance time.

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.

[0029] Reference Figure 1 As shown, this utility model provides a technical solution: a refrigerant diversion device for a cold storage refrigeration equipment, including a fixed pipe 1, a diversion cylinder 2, a base 3, a diversion pipe 4, and an adjustment structure 5. The diversion cylinder 2 is installed on the lower surface of the fixed pipe 1. The arc surface of the diversion cylinder 2 is fixed by means of the adjustment structure 5 and the base 3. A plurality of diversion pipes 4 are installed on the lower surface of the base 3. The arc surface of the diversion cylinder 2 is provided with the adjustment structure 5.

[0030] The specific settings and functions of its adjustment structure 5 will be explained in detail below.

[0031] Reference Figures 2 to 4As shown in this embodiment: the adjusting structure 5 includes an auxiliary ring 501, which is fixedly connected to the diverter cylinder 2. Two grooves 502 are formed on the arc surface of the auxiliary ring 501. Connecting blocks 503 are slidably connected to the inner walls of the grooves 502. Push blocks 504 are fixedly connected to one side of the connecting blocks 503. The upper surfaces of the two push blocks 504 are rotatably connected to the same rotating ring 505. The rotating ring 505 and the auxiliary ring 501 are threaded together. Two fixing blocks 506 are slidably connected to the inner wall of the diverter cylinder 2. Positioning blocks 507 are fixedly connected to the lower surface of the fixing blocks 506. A telescopic rod 508 is fixedly connected to one side of the positioning block 507. The telescopic rod 508... The other end is fixedly connected to the diverter cylinder 2. A spring 509 is fitted on the arc surface of the telescopic rod 508. The two ends of the spring 509 are fixedly connected to the diverter cylinder 2 and the positioning block 507, respectively. Two connecting blocks 510 are fixedly connected to the upper surface of the base 3. The connecting blocks 510 and the fixing block 506 are slidably connected. By setting the adjustment structure 5, the diverter cylinder 2 and the base 3 can be fixedly installed conveniently and quickly, so that personnel can inspect and maintain the inside, greatly increasing its service life and avoiding the cumbersome and time-consuming installation using screws. The arc surface of the rotating ring 505 is provided with anti-slip texture 511. The anti-slip texture 511 is evenly distributed on the rotating ring 505 to prevent slippage. The texture 511 increases the friction of the rotating ring 505, preventing hand slippage when rotating the ring 505. A limit rod 512 is fixedly connected to the inner wall of the slide groove 502. The limit rod 512 is slidably connected to the connecting block 503, limiting the connection block 503 and preventing it from shifting during movement. Ball bearings 513 are fixedly connected to both sides of the connecting block 503. The ball bearings 513 have a circular cross-section and reduce the friction of the connecting block 503, allowing it to move more smoothly within the slide groove 502. A pulley 5 is rotatably connected to one side of the fixed block 506. 15. The arc surface of pulley 515 is slidably connected to push block 504. Pulley 515 can reduce the friction between fixed block 506 and push block 504, thereby allowing fixed block 506 to move better. The arc surface of spring 509 is fitted with bellows 516. The two ends of bellows 516 are fixedly connected to diverter 2 and positioning block 507 respectively. Bellows 516 can protect spring 509 and prevent spring 509 from getting stuck with foreign objects and affecting its use. The other side of fixed block 506 is fixedly connected to guide block 514. Since guide block 514 is small in size, fixed block 506 can be better inserted into the interior of connecting block 510.

[0032] Detailed Instructions for Use: By setting the adjustment structure 5, first move the fixed tube 1 to move the diverter cylinder 2, placing the diverter cylinder 2 on the base 3 of the diverter tube 4. Then, rotate the rotating ring 505 with the help of the anti-slip texture 511. When the rotating ring 505 rotates, it will drive the push block 504 to move. The push block 504 will then drive the connecting block 503 to move within the groove 502 of the auxiliary ring 501, causing the push block 504 to push the fixed block 506 to move inside the diverter cylinder 2. When the fixed block 506 moves, the positioning block 507 will move. At the same time, the positioning block 507 will drive the spring 509 and the telescopic rod 508 to retract until the fixed block 506 is inserted into the connecting block 510. At this point, the diverter cylinder 2 and the base 3 are fixed. The anti-slip texture 511 can increase the stability of the diverter cylinder 2. The friction of the rotating ring 505 is increased to prevent the hand from slipping when the ring 505 is rotated. The limit rod 512 can limit the connecting block 503 to prevent the connecting block 503 from deviating during movement. The ball bearing 513 can reduce the friction of the connecting block 503, making the connecting block 503 move more smoothly in the slide groove 502. The pulley 515 can reduce the friction between the fixed block 506 and the push block 504, thereby allowing the fixed block 506 to move better. The bellows 516 can protect the spring 509 to prevent the spring 509 from getting stuck and affecting its use. Due to the small size of the guide block 514, the fixed block 506 can be better inserted into the interior of the connecting block 510.
