Description

Technical Field

[0001] This utility model relates to the technical field of food preservation, specifically to a low-temperature food preservation and storage device. Background Technology

[0002] In the field of low-temperature food preservation and storage, refrigerated display cases have become a common equipment for food preservation due to their controllable temperature and humidity environment and parameter monitoring functions. They are mostly used to achieve food classification and storage through stacked storage boxes.

[0003] However, the storage boxes in existing refrigerated display cases still have obvious defects during storage and retrieval: when placed in, the storage boxes are prone to direct collision with the inner wall of the cabinet, lacking an effective stable buffer protection structure. Especially for fragile foods such as eggs and fruits, the impact can easily cause the food to break or the storage boxes to deform.

[0004] Therefore, those skilled in the art have provided a food low-temperature preservation and storage device to solve the problems mentioned above. Utility Model Content

[0005] To address the aforementioned problems, this utility model provides a food low-temperature preservation and storage device.

[0006] To achieve the above objectives, the technical solution of this utility model is as follows:

[0007] A food low-temperature preservation and storage device, comprising:

[0008] A refrigerated display case has an open storage compartment with multiple storage boxes stacked inside. The top of each storage box is wider than its middle and lower parts. The middle and lower parts of each storage box form a gap between them and the inner walls of the two sides of the storage compartment. Multiple support parts are provided along the height direction on both sides of the storage compartment to support the top of the storage boxes.

[0009] Two rotating plates are rotatably arranged on opposite sides of the open side of the storage chamber;

[0010] A flexible strip, the two ends of which are respectively connected to one end of the two rotating plates;

[0011] An even number of elastic rings are symmetrically arranged on one side of the flexible strip, and the outer diameter of the elastic rings decreases from the middle to both sides.

[0012] The drive unit is slidably disposed along the length of the support unit and is used to drive the rotating plate away from one end of the flexible strip toward the open side away from the storage chamber;

[0013] When the storage box is placed in, the lower part of the storage box squeezes the elastic ring until the soft strip reaches the innermost end of its travel. The soft strip then tightens and forms an arc shape, and multiple elastic rings come into contact with each other, with the edges of the contact rings with the storage box on the same plane.

[0014] Preferably, the distance from the connecting end of the rotating plate and the flexible strip to the rotation point is greater than the distance from the other end to the rotation point. When the flexible strip is at the outermost end of the stroke, there is a gap between the other end of the rotating plate and the opposite side of the open side of the storage chamber.

[0015] Preferably, a cross is provided inside the elastic ring, and when the multiple elastic rings are in contact, the gap area between the multiple crosses faces the storage box.

[0016] Preferably, the width of the support portion is less than or equal to the height difference between the top and lower middle parts of one side of the storage box, and a gap is left between two adjacent storage boxes.

[0017] Preferably, the horizontal cross-section of the drive unit is T-shaped, and the contact end between the drive unit and the rotating plate is cylindrical.

[0018] In summary, this utility model has the following beneficial technical effects:

[0019] When the elastic ring in the lower part of the storage box is squeezed until the soft strip reaches the innermost end of its travel, the soft strip tightens and forms an arc shape. The arc structure can further enhance the cushioning effect and disperse the impact force when the food is placed in the box. At the same time, it forms a double cushioning protection with the elastic ring. Furthermore, multiple elastic rings come into contact with each other, and the edges of the contact with the storage box are on the same plane, ensuring that the cushioning force of each elastic ring is evenly transmitted. The cushioning effect of multiple elastic rings is consistent, avoiding direct collision with the inner wall and effectively protecting the food. Attached Figure Description

[0026] It is readily understood that, based on the technical solution of this utility model, those skilled in the art can propose various interchangeable structural methods and implementations without altering the essential spirit of this utility model. Therefore, the following detailed embodiments and accompanying drawings are merely illustrative descriptions of the technical solution of this utility model and should not be considered as the entirety of this utility model or as limitations or restrictions on the technical solution of this utility model.

[0027] A food low-temperature preservation and storage device, referring to Figure 1-4 ,include:

[0028] The refrigerator 1 has an open storage compartment 11 with a door at the opening. The temperature and humidity inside can be controlled to keep food fresh at low temperatures. The refrigerator 1 is equipped with a display screen that supports real-time display of key parameters such as temperature, humidity, and storage time. It also has an alarm function for abnormal parameters, so that users can intuitively grasp the preservation status and adjust the settings in time.

[0029] Multiple storage boxes 12 are stacked inside the storage chamber 11. The top width of the storage box 12 is greater than the width of the middle and lower part. The middle and lower part of the storage box 12 forms an interval area with the inner walls of both sides of the storage chamber 11. Multiple support parts 13 are provided on both sides of the storage chamber 11 along the height direction to support the top of the storage box 12. The upper surface of the support part 13 can be set as a plane. The support part 13 is located in the interval area. The width of the interval area can accommodate a palm to be inserted vertically. This size design fully considers ergonomics, allowing users to easily reach in and operate with their bare hands without the aid of tools, which is convenient for subsequent squeezing of the drive unit 5.

[0030] There are two rotating plates 2 located on opposite sides of the open side of the storage chamber 11. Specifically, the rotating plates 2 can be rotated via a bracket and a rotating shaft.

[0031] The flexible strip 3 has two ends that are rotatably connected to one end of each of the two rotating plates 2. It has a certain degree of elasticity and can be deformed, but it cannot be stretched. It is made of food-grade elastic silicone material, which has excellent low-temperature resistance and can maintain good flexibility in low-temperature environments. It does not release any odor and will not contaminate food. At the same time, its non-stretchable characteristic ensures the accuracy of power transmission.

[0032] An even number of elastic rings 4 are symmetrically arranged on one side of the soft strip 3, with at least four. The outer diameter of the elastic rings 4 decreases from the middle to both sides. This gradient size design allows the elastic rings 4 to fit fully with the lower part of the storage box 12, avoiding the tilting of the storage box 12 caused by uneven local force.

[0033] Multiple drive units 5 are provided and are slidably arranged along the length direction of the support unit 13. The support unit 13 is provided with a groove for guiding the drive unit 5 to slide, and is used to drive the rotating plate 2 away from the soft strip 3 on the open side away from the storage chamber 11.

[0034] When the two drive units 5 at the same height are pushed simultaneously and the soft strip 3 is driven to the outermost end of the stroke by the rotating plate 2, the soft strip 3 is parallel to the opposite side of the open side of the storage chamber 11, and there is a gap between the multiple elastic rings 4. This state is the state of the storage box 12 being taken out. In this state, the drive unit 5 will move outward a certain distance. The reserved stroke can prevent the drive unit 5 from being damaged due to excessive compression. At the same time, it forms obvious operation feedback, allowing the user to clearly perceive the state of taking out. It is convenient to continue pressing the drive unit 5 when the storage box 12 needs to be taken out next time. During this process, the multiple elastic rings 4 move outward and simultaneously to both sides. The multi-point synchronous pushing structure can make the storage box 12 be subjected to balanced force, avoid jamming or tilting when taking out, and make the pushing speed stable and controllable. It prevents the food from falling due to inertia and can slowly push out the storage box 12.

[0035] When the storage box 12 is placed inside, the lower part of the storage box 12 compresses the elastic ring 4 until the soft strip 3 reaches the innermost end of its travel. The soft strip 3 then tightens and forms an arc shape. The arc structure further enhances the cushioning effect and disperses the impact force when the box is placed inside. At the same time, it forms a double cushioning protection with the elastic ring 4. The multiple elastic rings 4 are close to each other and their contact edges with the storage box 12 are on the same plane. The flush contact surface design ensures that the cushioning force of each elastic ring 4 is evenly transmitted, avoiding excessive local pressure that could cause the storage box 12 to deform or damage the food. When the box is placed inside, it can provide cushioning and prevent direct collision with the inner wall. The cushioning effect of the multiple elastic rings 4 is consistent, effectively protecting fragile food (such as eggs and fruits) and the storage box 12 itself.

[0036] The distance from the connecting end of the rotating plate 2 and the soft strip 3 to the rotation point is greater than the distance from the other end to the rotation point. When the soft strip 3 is at the outermost end of the stroke, there is a gap between the other end of the rotating plate 2 and the opposite side of the open side of the storage chamber 11. The reserved gap prevents the rotating plate 2 from colliding and wearing with the cabinet, while providing sufficient space for the rotating plate 2 to rotate, ensuring smooth operation of the mechanism. Using the lever principle, the storage box 12 can slide out easily.

[0037] A cross 41 is provided inside the elastic ring 4. The cross 41 is integrally molded from high-strength engineering plastic, which can enhance the structural stability of the elastic ring 4 and prevent permanent deformation caused by long-term compression, while not affecting its elastic cushioning performance. When multiple elastic rings 4 are in contact, the gap area between multiple crosses 41 is aligned with the storage box 12. The gap area and the elastic deformation area of ​​the elastic ring 4 complement each other, which can provide stable support and ensure the cushioning effect. This prevents the storage box 12 from shaking excessively when placed in, and also prevents it from being impacted due to insufficient cushioning. It can provide relatively stable cushioning. At the same time, the contact point of adjacent elastic rings 4 is also the corresponding gap area of ​​cross 41. This staggered contact design avoids stress concentration when the elastic rings 4 are in contact, extends their service life, and makes the overall cushioning performance more balanced, with better stability and optimal elasticity.

[0038] The width of the support part 13 is less than or equal to the height difference between the top and lower middle parts of one side of the storage box 12, and there is a gap between two adjacent storage boxes 12 to avoid excessive friction between two adjacent storage boxes 12, which can reduce the difficulty of sliding out and allow the lower storage box 12 to be taken out directly.

[0039] The horizontal cross-section of the drive unit 5 is T-shaped, which makes it easy for a hand to reach into the interval area and squeeze the drive unit 5 directly and quickly. The contact end between the drive unit 5 and the rotating plate 2 is cylindrical, which can reduce the friction at the contact point.

[0040] The technical scope of this utility model is not limited to the content described above. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this utility model, and all such modifications and variations should fall within the protection scope of this utility model.
