Description

Technical Field

[0001] The utility model relates to the technical field of preservation devices, in particular to a low-temperature preservation device for crab roe. Background Art

[0002] Crab roe is mainly tissues such as ovaries and digestive glands in female crabs, showing orange-yellow or yellow color, rich in nutrients such as protein, phospholipids, and oils, with a unique flavor and delicious taste. During the storage of crab roe, low-temperature preservation is required. On the one hand, crab roe is rich in nutrients such as protein and fat, and is prone to breed bacteria and microorganisms at room temperature, thus deteriorating. Low temperature can effectively inhibit the growth and reproduction of bacteria, thereby extending the shelf life of crab roe. On the other hand, high temperature will promote the rapid oxidation of oils in crab roe, producing peculiar smells and harmful substances, affecting the taste and quality. Low temperature can slow down the oxidation rate of oils and maintain its freshness. In addition, low-temperature preservation also helps to maintain the color and texture of crab roe.

[0003] Existing low-temperature preservation of crab roe usually uses a freezer or a refrigerator for storage. However, since many freezers have a long depth, and in order to improve storage efficiency, the internal space layout of the freezer is generally relatively compact, and crab roe is generally put into containers in batches for low-temperature preservation. When it is necessary to take out the batch of crab roe at a deeper position inside, it is generally quite difficult. It is necessary to take out all the outer ones before touching the internal crab roe. This process is time-consuming and laborious, increasing the complexity and inconvenience of the operation, and resulting in a reduction in work efficiency. Summary of the Utility Model

[0004] The purpose of the utility model is to solve the problem that when the above-mentioned equipment is used, due to the long depth of the freezer for low-temperature preservation of crab roe and the compact internal space for improving storage efficiency during use, and the crab roe is put into containers in batches for low-temperature preservation, it is difficult to take out the batch of crab roe at a deeper position inside, and it is necessary to move the outer ones to touch it, resulting in a reduction in work efficiency.

Specific embodiments

[0021] In order to more clearly understand the above objects, features and advantages of the present utility model, the following further describes the present utility model with reference to the accompanying drawings and embodiments. It should be noted that, without conflict, the embodiments of the present application and the features in the embodiments can be combined with each other.

[0022] In the following description, many specific details are set forth in order to fully understand the present utility model. However, the present utility model can also be implemented in other ways different from those described herein. Therefore, the present utility model is not limited by the specific embodiments disclosed in the following specification.

[0023] Embodiment 1, as Figures 1-4 shown, the present utility model provides a low-temperature preservation device for crab roe, including a refrigerator 1. Two mounting holes 2 are opened on the outer surface of the refrigerator 1. Bearings 3 are fixedly inserted into the inner surfaces of the two mounting holes 2. A threaded rod 4 is fixedly inserted between the two bearings 3. A threaded block 5 is threadedly connected to the outer surface of the threaded rod 4. A motor 6 is fixedly connected to one side of the outer wall of the threaded rod 4. Four mounting plates 7 are fixedly installed on the inner surface of the refrigerator 1. First chutes 8 are opened on one side of the outer walls of the four mounting plates 7. First sliders 9 are slidably embedded in the inner surfaces of the four first chutes 8. Two slide rails 10 are fixedly installed on the inner surface of the refrigerator 1. Second sliders 11 are movably sleeved on the outer surfaces of the two slide rails 10. A fixed frame 12 is fixedly connected between the tops of the two second sliders 11. And the outer surfaces of the four first sliders 9 are fixedly connected to the outer surface of the fixed frame 12.

[0024] The effect achieved by the entire Embodiment 1 is that when it is necessary to take out the crab roe deep inside the freezer 1, first start the motor 6. The output end of the motor 6 is connected to the threaded rod 4, and its rotational motion drives the threaded rod 4 to rotate. Since the outer wall of the threaded rod 4 is tightly connected to the inner wall of the threaded block 5 through threads, when the threaded rod 4 rotates, it will drive the threaded block 5 to move back and forth along the horizontal direction. As the threaded block 5 moves, it further pulls the fixed frame 12 connected to it to move back and forth. Seven placement plates 17 are installed on the fixed frame 12, and these placement plates 17 are used to store the crab roe. Therefore, when the fixed frame 12 is removed from the inside of the freezer 1, the placement plates 17 and the crab roe on their tops are also taken out, which greatly facilitates the staff to take the crab roe. This process not only improves work efficiency, but also reduces the number of times the staff enters the inside of the freezer 1 to operate, and also reduces the labor intensity of the staff.

[0025] Embodiment 2 is as Figures 2-4 shown. A plurality of positioning grooves 13 are formed on the outer wall of the fixed frame 12. The inner walls of seven of the plurality of positioning grooves 13 are all movably inserted with positioning rods 14. A third slider 15 is fixedly connected to one side of the outer walls of the seven positioning rods 14. A spring 16 is fixedly connected to one side of the outer walls of the seven third sliders 15. A placement plate 17 is movably sleeved between the outer walls of the seven third sliders 15. A set of second chutes 18 are formed at the bottoms of the seven placement plates 17, and the outer walls of the seven third sliders 15 are movably embedded in the interiors of the four second chutes 18. A pull plate 19 is fixedly connected between the bottoms of the seven third sliders 15. Two hinges 20 are fixedly installed on one side of the outer wall of the freezer 1. A cabinet door 21 is fixedly connected between the rotating ends of the two hinges 20. A handle 22 is fixedly installed on one side of the outer wall of the cabinet door 21.

[0026] The effect achieved by the entire Embodiment 2 is that by pulling the two pull plates 19 at the bottom of the placement plate 17, the two pull plates 19 drive the four third sliders 15 on their tops to smoothly move in the corresponding second chutes 18. This action causes the four positioning rods 14 to disengage from the corresponding positioning grooves 13, thus realizing the quick disassembly and installation of the placement plate 17. By providing a plurality of positioning grooves 13 on the outer wall of the fixed frame 12, it allows the staff to flexibly adjust the spacing between the placement plates 17 according to the actual size of the crab roe packaging, ensuring the safety and stability of the crab roe storage, while maximizing the utilization of the internal space of the freezer 1, improving the storage efficiency and flexibility, and further meeting different storage requirements.

[0027] Working principle: During the operation, in response to the convenient extraction requirement of the crab roe deep in the freezer 1, the motor 6 is first started, and its power output directly drives the threaded rod 4 to perform a rotational motion. Since the outer wall of the threaded rod 4 is threadedly connected to the inner wall of the threaded block 5, this rotational action is then converted into a linear motion of the threaded block 5 in the horizontal direction. The threaded block 5, as a transmission medium, pulls the fixed frame 12 and the seven placement plates 17 carried thereon to move forward synchronously, effectively extending the crab roe storage area to the outside of the freezer 1, greatly facilitating the access operation of the operator. To ensure the smoothness and precision of the moving process, a sliding fit structure of four groups of first chutes 8 and first sliders 9, as well as a stable support system of double rails 10 and second sliders 11, are adopted. The two work together not only to enhance the stability of the fixed frame 12 during movement but also to ensure the smoothness of the entire moving process without obstruction. In addition, by pulling the two pull plates 19 at the bottom of the placement plate 17 towards each other, the two pull plates 19 then drive the four third sliders 15 to smoothly move inside the corresponding second chutes 18. During this process, the two third sliders 15 drive the four positioning rods 14 to disengage from the corresponding positioning grooves 13 and simultaneously compress the four springs 16 to store elastic potential energy. When the placement plate 17 is adjusted to the required height, by releasing the two pull plates 19, the four springs 16 release energy, pushing the positioning rods 14 to automatically reset into the corresponding positioning grooves 13, realizing the quick locking or release of the placement plate 17. This mechanism not only simplifies the operation process but also ensures the stable installation of the placement plate 17 at different heights and spacings. Moreover, multiple groups of positioning grooves 13 are provided on the outer wall of the fixed frame 12, providing great flexibility for the diversified storage of crab roe packaging. The operator can flexibly adjust the spacing between the placement plates 17 according to the actual packaging size to maximize the utilization of space.

[0028] The above is only a preferred embodiment of the present invention, and it is not a limitation of the present invention in other forms. Any person skilled in the art may use the disclosed technical content to make changes or modifications into equivalent embodiments with equivalent changes and apply them to other fields. However, as long as it does not depart from the technical solution content of the present invention, any simple modification, equivalent change, and modification made to the above embodiments based on the technical essence of the present invention still fall within the protection scope of the technical solution of the present invention.
