Abstract
Description
Technical Field
[0001] This utility model belongs to the field of ultra-low temperature cold storage technology, and more specifically, it relates to an insulated storage structure for an ultra-low temperature cold storage. Background Technology
[0002] Ultra-low temperature cold storage is a type of cold storage specifically designed to maintain an extremely low temperature storage environment, typically reaching -40°C or even lower. This type of cold storage is mainly used to store items with extremely strict temperature requirements, such as pharmaceutical products (vaccines, blood products), certain foods (such as ice cream, frozen foods), and for scientific research purposes (such as sample storage).
[0003] When ultra-low temperature cold storage is in use, if staff need to frequently access items inside, high temperatures and humidity from the outside can easily enter the cold storage, causing increased temperature fluctuations inside the cold storage and making it easier for moisture to condense inside, thus affecting the lifespan and insulation performance of the cold storage.
[0004] Therefore, in view of this, we have studied and improved the existing structure and its shortcomings, and provided an insulated storage structure for ultra-low temperature cold storage, in order to achieve a more practical purpose. Utility Model Content
[0005] To solve the above-mentioned technical problems, this utility model provides an insulated storage structure for an ultra-low temperature cold storage, achieved through the following specific technical means:
[0006] An insulated structure for an ultra-low temperature cold storage includes a cold storage body. A door is installed on one side of the cold storage body, and a first sealing gasket is installed on the side of the door closest to the cold storage body. An edge sealing assembly is installed on one side inside the cold storage body. A pair of mounting plates are symmetrically installed on one side inside the cold storage body. Each pair of mounting plates has a first sliding groove on its opposite side. A first isolation plate and a second isolation plate are respectively installed in the pair of first sliding grooves. A groove is provided on one side of the first isolation plate, and a protrusion is provided on one side of the second isolation plate. A driving assembly is installed between the pair of first sliding grooves.
[0007] Furthermore, the edge sealing assembly includes a frame installed inside the cold storage body on the side near the door, and the frame has a second groove on the side near the door, in which a second sealing gasket is slidably installed.
[0008] Furthermore, the second sealing gasket has several compression springs installed on one side located within the second groove, and the other end of the compression springs is connected to one side of the second groove.
[0009] Furthermore, the drive assembly includes a bidirectional screw, which is rotatably mounted between a pair of first sliding grooves, and the bidirectional screw passes through the left and right sides of the first and second isolation plates and is threadedly connected to the first and second isolation plates. A driven bevel gear is mounted on one side of the bidirectional screw.
[0010] Furthermore, a motor is mounted on one side of one of the pair of mounting plates, and a driving bevel gear is mounted on one side of the motor output end via a coupling, and the driving bevel gear is meshed with the driven bevel gear.
[0011] Furthermore, both of the mounting plates, the first isolation plate, and the second isolation plate are insulation plates.
[0012] Compared with the prior art, the present invention has the following beneficial effects:
[0013] The insulation structure of the ultra-low temperature cold storage in this utility model, through the coordinated use of the cold storage body, door, first sealing gasket, mounting plate, first slide groove, first isolation plate, second isolation plate, groove, protrusion, frame, second slide groove, second sealing gasket, compression spring, bidirectional screw, driven bevel gear, motor, and driving bevel gear, facilitates the isolation of the cold storage body from the outside world through the door, mounting plate, first isolation plate, and second isolation plate. This creates a buffer zone between the door and the pair of mounting plates when items inside the cold storage need to be stored or retrieved, preventing high temperatures and moisture from directly entering the interior of the cold storage body. This improves the insulation effect of the -60°C ultra-low temperature cold storage and extends its service life. Attached Figure Description

[0023] Example:
[0024] As attached Figure 1 To be continued Figure 4 As shown:
[0025] This utility model provides an insulated structure for an ultra-low temperature cold storage, including a cold storage body 1. A door 2 is installed on one side of the cold storage body 1. A first sealing gasket 3 is installed on the side of the door 2 closest to the cold storage body 1. An edge sealing assembly is installed on one side inside the cold storage body 1. A pair of mounting plates 4 are symmetrically installed on one side inside the cold storage body 1. Each pair of mounting plates 4 has a first sliding groove 5 on its opposite side. A first isolation plate 6 and a second isolation plate 7 are respectively installed in the pair of first sliding grooves 5. A groove 8 is provided on one side of the first isolation plate 6, and a protrusion 9 is provided on one side of the second isolation plate 7. A driving assembly is installed between the pair of first sliding grooves 5. The position and size of the groove 8 match the position and size of the protrusion 9. The engagement between the groove 8 and the protrusion 9 reduces the occurrence of thermal bridging. At the same time, a buffer area is formed between the door 2 and the pair of mounting plates 4 to prevent the air inside the cold storage body 1 from directly contacting the outside air.
[0026] The edge sealing assembly includes a frame 10, which is installed inside the cold storage body 1 on the side near the door 2. The frame 10 has a second groove 11 on the side near the door 2, and a second sealing gasket 12 is slidably installed in the second groove 11.
[0027] The second sealing gasket 12 has several compression springs 13 installed on one side inside the second slide groove 11, and the other end of the compression spring 13 is connected to one side of the second slide groove 11. Through the rebound of the compression spring 13, the second sealing gasket 12 is always in close contact with the door 2 and the first sealing gasket 3, thereby reducing the entry of heat and moisture from the gap between the door 2 and the cold storage body 1.
[0028] The drive assembly includes a bidirectional screw 14, which is rotatably mounted between a pair of first sliding grooves 5. The bidirectional screw 14 passes through the left and right sides of the first isolation plate 6 and the second isolation plate 7 and is threadedly connected to the first isolation plate 6 and the second isolation plate 7. A driven bevel gear 15 is installed on one side of the bidirectional screw 14. Through the rotation of the bidirectional screw 14, under the limiting action of the first sliding grooves 5, the first isolation plate 6 and the second isolation plate 7 move towards each other or move away from each other simultaneously.
[0029] One of the pair of mounting plates 4 has a motor 16 mounted on one side. The output end of the motor 16 is connected to a drive bevel gear 17 via a coupling. The drive bevel gear 17 is meshed with the driven bevel gear 15. The motor 16 drives the drive bevel gear 17 to rotate. Since the drive bevel gear 17 is meshed with the driven bevel gear 15, the driven bevel gear 15 rotates together and drives the bidirectional screw 14 to rotate, thereby driving the first isolation plate 6 and the second isolation plate 7 to move.
[0030] Among them, the pair of mounting plates 4, the first isolation plate 6, and the second isolation plate 7 are all insulation boards. The insulation boards can be made of materials such as polyurethane, which have good thermal insulation performance, sealing performance, and water resistance.
[0031] The working principle of this embodiment is as follows: During use, the groove 8 on one side of the first isolation plate 6 engages with the protrusion 9 on one side of the second isolation plate 7, reducing heat exchange between the two sides of the first isolation plate 6 and the second isolation plate 7. Simultaneously, the rebound of the compression spring 13 ensures that the second sealing gasket 12 remains tightly pressed against the door 2 and the first sealing gasket 3, thereby reducing the entry of heat and moisture through the gap between the door 2 and the cold storage body 1. This ensures the stability of the internal temperature of the cold storage body 1 at -60 degrees Celsius. When it is necessary to retrieve or place items inside the cold storage body 1... The staff first opens the door 2, and after entering the cold storage body 1, closes the door 2. Then, they turn on the motor 16, which drives the driving bevel gear 17 to rotate. Since the driving bevel gear 17 is meshed with the driven bevel gear 15, the driven bevel gear 15 rotates together and drives the bidirectional screw 14 to rotate, which in turn drives the first isolation plate 6 and the second isolation plate 7 to move in opposite directions. At this time, the staff can enter the cold storage body 1 to retrieve and place items. After the items are retrieved and placed, the staff turns on the motor 16 again, so that the pair of isolation plates can be re-engaged and the door 2 can be opened to leave.
[0032] The embodiments of this utility model are given for illustrative and descriptive purposes only, and are not intended to be exhaustive or to limit the utility model to the forms disclosed. Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described in order to better illustrate the principles and practical applications of this utility model, and to enable those skilled in the art to understand this utility model and design various embodiments with various modifications suitable for a particular purpose.
