Description

Technical Field

[0001] The utility model relates to the technical field of controlled atmosphere storage, in particular to a food freezing controlled atmosphere storage. Background Technique

[0002] A controlled atmosphere storage, also known as a controlled atmosphere storage library, is the most advanced method for storing and preserving fruits and vegetables today. On the basis of refrigeration, it adds gas composition regulation. By controlling conditions such as temperature, humidity, carbon dioxide, oxygen concentration, and ethylene concentration in the storage environment, it inhibits the respiration of fruits and vegetables, delays their metabolic process, better maintains the freshness and commerciality of fruits and vegetables, and extends the storage period and freshness preservation period (sales shelf life) of fruits and vegetables. Generally, controlled atmosphere storage can extend the storage period by 0.5 - 1 times compared with ordinary refrigeration. The fruits and vegetables stored in the controlled atmosphere storage wake up from the dormant state first after leaving the warehouse, which enables the freshness preservation period (sales shelf life) of the fruits and vegetables to be extended by 21 - 28 days after leaving the warehouse, which is 4 - 5 times that of an ordinary refrigerated warehouse.

[0003] The existing patent (publication number: CN211084567U) discloses a food freezing controlled atmosphere storage, the structure of which includes a library body, a convenient explosion-proof door, a protective shell, a control cabinet, a pressure gauge, a base, a reflux pump, a condenser, a coil pipe, a blower, a drain valve, and a power cord. The utility model sets a convenient explosion-proof door on the left side of the front end of the library body, fits the door frame with the front end of the library body, bolts and locks the explosion-proof door to the door frame through a hinge. When the explosion-proof door needs to be opened, press the button in the control cabinet to start the heating wire for preheating for 5 minutes, causing the ice around the explosion-proof door to melt. Open the explosion-proof door through the handle to an appropriate angle, then rotate the knob to drive the gear disk to rotate, and the gear disk drives the rack to slowly move down until the support pad fits firmly with the bottom end surface of the library body, so as to prevent the explosion-proof door from sliding randomly, achieving the beneficial effect of melting the ice around the explosion-proof door and avoiding noise generated by the collision between the explosion-proof door and the door frame. The inventor found the following problems in the process of implementing the present utility model: 1. The traditional controlled atmosphere storage is large in volume and inconvenient to move. When the position of the controlled atmosphere storage needs to be moved and replaced, multiple workers are required to carry and move the controlled atmosphere storage at the same time, greatly increasing the labor intensity of the workers and thus greatly reducing the work efficiency; 2. The traditional controlled atmosphere storage lacks a buffer device during the moving process. When the controlled atmosphere storage moves to a bumpy section of the road, due to the bumps on the ground, it is easy for the parts inside the controlled atmosphere storage to become loose or fall off, thus increasing the maintenance cost of the controlled atmosphere storage. Content of the Utility Model

Limiting blocks 18 are arranged on both sides of the four pressure plates 17. Guide posts 19 are arranged at the bottom ends of the four pressure plates 17. Universal wheels 20 are arranged at the bottom ends of the four guide posts 19. Chute grooves 21 are provided on the inner walls of both sides inside the four grooves 8.

[0022] In this embodiment, as Figure 1 shown, the housing assembly 1 includes a base 101. An atmosphere-controlled storage main body 102 is arranged at the top end of the base 101. Support legs 103 are arranged at the four corners outside the bottom end of the base 101. A motor 104 is arranged on one side of the base 101.

[0023] In this embodiment, as Figure 1 shown, the central axis of the motor 104 is consistent with the central axis of the connecting shaft 3; enabling the four threaded sleeves 11 to move synchronously, thereby greatly improving the convenience of the atmosphere-controlled storage during movement.

[0024] In this embodiment, as Figure 4 shown, the main bevel gears 4 and the double-headed gear 7 are both meshed with the sub-bevel gears 10; realizing the rapid movement and replacement of the position of the atmosphere-controlled storage main body 102 according to the needs of the user, greatly improving the convenience of the atmosphere-controlled storage main body 102 during movement, thereby reducing the labor intensity of the staff and greatly improving the working efficiency of the food freezing and controlled atmosphere storage during movement.

[0027] In this embodiment, Figure 3 As shown, the outer dimensions of the limit block 18 are consistent with the inner dimensions of the limit slot 15, so that the moving direction of the guide column 19 is single, avoiding the guide column 19 from tilting during movement, thereby greatly improving the stability of the guide column 19 during movement.

[0028] The use method and advantages of the utility model: When the food refrigeration and air conditioning storage is in use, the working process is as follows:

[0029] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, first, when the main body 102 of the gas conditioning storage needs to be moved, the motor 104 is started to drive the connecting shaft 3 to rotate, and the connecting shaft 3 drives the two sets of main bevel gears 4 to rotate. At this time, the two main bevel gears 4 are respectively engaged to drive the two sets of double-headed gears 7 to rotate, and the two double-headed gears 7 are engaged to drive the two sets of secondary bevel gears 10 to rotate. At this time, the two secondary bevel gears 10 drive the screw rod 9 to rotate, and the screw rod 9 drives the threaded sleeve 11 to move downward under the cooperation of the slider 12 and the slide groove 21. At the same time, the threaded sleeve 11 drives the universal wheel 20 to move downward synchronously through the mounting plate 13 and the sleeve 14, so that the universal wheel 20 contacts the ground together, until the universal wheel 20 drives the supporting leg 103 to break away from the contact with the ground through the base 101, and then pushes the base 101, so that the base 101 passes through the universal wheel 20 It drives the main body 102 of the controlled atmosphere storage to move, and realizes the rapid movement and replacement of the position of the main body 102 of the controlled atmosphere storage according to the needs of the user, which greatly improves the convenience of the main body 102 of the controlled atmosphere storage during movement, thereby reducing the labor intensity of the staff and greatly improving the work efficiency of the food refrigeration controlled atmosphere storage during movement. When the main body 102 of the controlled atmosphere storage moves to a bumpy section, the guide column 19 will drive the pressure plate 17 to move toward the inside of the sleeve 14 with the cooperation of the limit block 18 and the limit groove 15. At the same time, the pressure plate 17 compresses the spring 16 to achieve the buffering effect of the main body 102 of the controlled atmosphere storage during movement, and solves the problem of loosening or falling off of parts inside the controlled atmosphere storage due to the bumps of the ground, thereby greatly reducing the maintenance cost of the main body 102 of the controlled atmosphere storage, and thus meeting the needs of food refrigeration controlled atmosphere storage.
