Description
Technical Field
[0001] This utility model relates to the field of fruit juice preservation technology, and in particular to a fruit juice low-temperature preservation device. Background Technology
[0002] In today's food preservation industry, with consumers' increasing demands for juice quality, low-temperature preservation devices for juice are receiving more and more attention. Juice is rich in various vitamins, minerals, and flavor compounds; however, it is highly susceptible to spoilage due to factors such as temperature, oxygen, and microorganisms, leading to a decline in taste and nutrient loss. Low-temperature preservation technology can effectively mitigate these adverse changes, extend the shelf life of juice, and ensure that consumers can enjoy juice that is close to freshly squeezed. Therefore, related devices play a crucial role in all stages of juice production, storage, transportation, and sales.
[0003] Traditional juice preservation devices mostly employ a relatively simple fixed structure design. For example, common refrigerators typically have multiple fixed shelves inside, welded or bolted to the cabinet, with a fixed spacing between shelves. Technically, they rely on a refrigeration system to maintain a low-temperature environment. A compressor compresses the refrigerant, causing it to vaporize and absorb heat in the evaporator, thus removing heat from the cabinet and controlling the temperature within the suitable range for juice preservation, generally 0-4℃. For sealing, the cabinet door usually uses rubber sealing strips to reduce the entry of hot air and microorganisms from the outside.
[0004] Traditional juice preservation devices cannot adjust the height of the shelf according to the varying heights of the juice bottles, resulting in a limited variety of juices that can be stored. Therefore, a new juice preservation device is proposed to solve this problem. Utility Model Content
[0005] To overcome the above shortcomings, this utility model provides a low-temperature preservation device for fruit juice, which aims to improve the problem in the prior art that the height of the shelf cannot be adjusted according to the height of the fruit juice bottle due to the different heights of the fruit juice bottles, resulting in a limited variety of fruit juices that can be stored.

[0033] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0034] Reference Figure 1 , Figure 2 , Figure 3 and Figure 4 This utility model provides an embodiment of a juice low-temperature preservation device, including a preservation box 1. A door panel 2 is provided on the side wall of the preservation box 1. The door panel 2 ensures the airtightness of the low-temperature environment inside the box when closed, and can also be opened to facilitate operation, maintenance, and juice storage and retrieval by the operator. A handle 3 fixedly connected to the side wall of the door panel 2 provides a convenient point of leverage for opening and closing the door panel 2. A fixed frame 4 fixedly connected inside the preservation box 1 plays a key supporting and structural role. A sliding sleeve 7 slidably connected to the side wall of the fixed frame 4 has flexible displacement characteristics and can slide smoothly along the side wall of the fixed frame 4. An installation sleeve 5 fixedly connected to the side wall of the sliding sleeve 7 acts as a connecting bridge. A shelf 6 slidably connected inside the installation sleeve 5 is a bearing surface that directly contacts the juice, and juice containers of different specifications and sizes can be placed on it. An adjustment component is provided on the side wall of the sliding sleeve 7. The installation plate 8 in the adjustment component is fixedly connected to the side wall of the sliding sleeve 7, providing an installation platform for subsequent components and ensuring the stability of the entire adjustment component. The rotating plate 10, rotatably connected inside the mounting plate 8, can rotate flexibly under manual intervention. A handle 11 is fixedly connected to the lower surface of the rotating plate 10. The operator can easily drive the rotating plate 10 by holding the handle 11 and rotating it. A rotating block 12 is rotatably connected to the upper surface of the rotating plate 10. A pull rope 13 is fixedly connected to the side wall of the rotating block 12. A locking block 15 is fixedly connected to one end of the pull rope 13. A first spring 14 sleeved on the side wall of the pull rope 13 has an elastic reset function. A slot 9 opened inside the fixing frame 4 precisely matches the locking block 15. The slot 9 provides a precise insertion position for the locking block 15. Whether the two are engaged or not determines whether the shelf 6 is in a fixed or adjustable state. The side wall of the locking block 15 is slidably connected inside the mounting plate 8. One end of the first spring 14 is fixedly connected inside the mounting plate 8, and the other end is fixedly connected to the side wall of the locking block 15, providing a reliable elastic driving force for the entire adjustment and locking mechanism. The locking components on the lower surface of the shelf 6 further enhance the stability of the shelf 6 after it is adjusted to the appropriate position, and prevent the shelf 6 from being accidentally shaken or displaced during the operation, transportation or daily use of the device, which could lead to problems such as juice spillage or collision damage, thus ensuring the safety and stability of juice storage.
[0035] When using this device to preserve the freshness of juice and store juice bottles of different sizes, the operator first holds the handle 11 and rotates it. Rotating the handle 11 causes the rotating plate 10 to start rotating. The rotating plate 10 converts the torque applied by the operator into its own rotational motion. The rotation of the rotating plate 10 pulls the pull rope 13, transmitting the rotational effect of the rotating plate 10 to the locking block 15. As the pull rope 13 pulls the locking block 15 to slide out of the locking groove 9, the first spring 14 is compressed and contracts. Under normal conditions, the first spring 14, with its own elastic properties, provides a stable pushing force to the locking block 15 into the locking groove 9 to maintain the fixation of the shelf 6. When compressed by the external force of the pull rope 13, it contracts and accumulates energy to prepare for the subsequent reset action. Once the locking block 15 disengages from the slot 9, the shelf 6 loses its fixing effect. At this point, the sliding sleeve 7 can utilize its flexible movement characteristics. By sliding the sliding sleeve 7 upwards along the side wall of the fixing frame 4, the operator can precisely adjust the spacing between the shelves 6 according to the height requirements of different sized juice bottles, thereby achieving efficient space utilization. Whether it is a large-capacity jug of juice or a small bottle of juice, a suitable placement position can be found. When the appropriate position is reached, the handle 11 is released. At this time, the first spring 14 rebounds, and with the elastic potential energy accumulated earlier, pushes the locking block 15 back into the slot 9. The engagement of the locking block 15 and the slot 9 fixes the shelf 6 in place again.
[0036] Reference Figure 3 and Figure 5The locking assembly includes a locking plate 17, the upper surface of which is fixedly connected to the lower surface of the shelf 6, providing a point of force for subsequent locking actions. An mounting block 16 is fixedly connected inside the mounting sleeve 5, with a hook 24 on its lower surface that precisely engages with the locking plate 17, firmly fixing the shelf 6 in its current position. This effectively prevents displacement of the shelf 6 due to vibration, shaking, or other external forces during device operation, handling, or daily use. A sliding block 18 is slidably connected inside the mounting block 16. A second spring 19 is installed inside the mounting block 16, with one end fixedly connected inside the mounting block 16 and the other end fixedly connected to the side wall of the sliding block 18. A rotating bar 20 is rotatably connected to the upper surface of the mounting block 16, and its side wall is slidably connected inside the sliding block 18. By manually operating the rotating bar 20, the operator can precisely transmit external force to the sliding block 18, causing displacement changes in the sliding block 18, thereby controlling the state of the hook 24. The connecting rod 21, which is fixedly connected to the side wall of the sliding block 18, has one end attached to the side wall of the shelf 6. It can not only move with the sliding block 18 and play a linkage role, but also provide auxiliary support and limit function for the side of the shelf 6 to a certain extent, preventing unnecessary deviation of the shelf 6 in the horizontal direction. The fixed plate 23, which is fixedly connected to the lower surface of the sliding block 18, provides stable sliding track support for the hook 24. The side wall of the hook 24 is slidably connected inside the fixed plate 23, ensuring that the hook 24 always moves along the predetermined trajectory during the movement, avoiding problems such as jamming or skew that affect the locking effect. The bottom of the mounting block 16 is fixedly connected to the second fixed frame 22. The side wall of the hook 24 is rotatably connected inside the second fixed frame 22, so that the hook 24 can rotate flexibly around the second fixed frame 22 as the axis during the process of engaging and disengaging with the plate 17, optimizing the convenience of engaging and unlocking operations.
[0037] When it is necessary to retrieve the juice from the inner part, push the shelf 6 inward. The movement of the shelf 6 causes the connecting rod 21 to be pushed. One end of the connecting rod 21 is attached to the side wall of the shelf 6, and the inward pushing force on the shelf 6 is transmitted to the sliding block 18, which in turn causes the sliding block 18 to slide backward. The backward sliding of the sliding block 18 compresses the second spring 19. The second spring 19, due to its elastic properties, provides stable support for the sliding block 18 and its connected components under normal operating conditions, maintaining the locked state of the hook 24 and the locking plate 17, thus ensuring the fixation of the shelf 6. When compressed, it accumulates energy through contraction. As the sliding block 18 slides, the rotating bar 20 slides and locks inside the sliding block 18. The upper surface of the rotating bar 20 is rotatably connected to the mounting block 16, and its sidewall cooperates with the sliding block 18. Through its sliding and locking actions, it changes the motion state of the sliding block 18 and related components. Simultaneously, the sliding of the sliding block 18 causes the fixing plate 23 to move. The lower surface of the fixing plate 23 is fixedly connected to the lower surface of the sliding block 18, providing a stable sliding support track for the hook 24, causing the hook 24 to rotate as the fixing plate 23 moves. The rotation of the hook 24 directly releases the lock between it and the locking plate 17, breaking the fixed constraint of the shelf 6. At this point, the shelf 6 loses its fixing effect and can be pulled outwards, making it easy to take out the juice. This greatly improves the convenience and efficiency of taking out items in the low-temperature preservation device, meeting the needs of taking out items in actual use.
[0038] Working principle: When using this device to preserve the freshness of juice and storing juice bottles of different sizes, first, rotate the handle 11 to make the rotating plate 10 rotate, which in turn causes the pull rope 13 to pull the locking block 15 to slide out of the locking groove 9. This causes the first spring 14 to be compressed and contracted, thus disengaging the locking block 15 from the locking groove 9. At this time, the shelf 6 loses its fixing effect. By sliding the sliding sleeve 7 upward, the spacing between the shelf 6 can be adjusted. When the appropriate position is reached, release the handle 11 to allow the first spring 14 to rebound and push. The locking block 15 re-enters the slot 9 to complete the adjustment. When it is necessary to take out the juice from the inside, the shelf 6 is pushed inward, causing the connecting rod 21 to slide backward under the force, which in turn squeezes the second spring 19, causing the rotating bar 20 to slide and lock inside the sliding block 18. At the same time, the sliding of the sliding block 18 will drive the fixed plate 23 to move, causing the hook 24 to start to rotate due to the movement of the fixed plate 23, thereby releasing the lock between it and the locking plate 17. At this time, the shelf 6 loses its fixing effect and can be pulled out to make it easier to take out the juice.
[0039] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
