Description

Technical Field

[0001] This utility model relates to the field of transfer box technology, and in particular to a low-temperature transfer box for biological products. Background Technology

[0002] A cryogenic transport box for biological products is a device specifically designed to maintain the required low-temperature environment for biological products during transportation. It can precisely control the temperature, ensuring that the temperature inside the box remains within the appropriate temperature range for the biological products.

[0003] Currently available biological products have high requirements for stable transportation, but bumps often occur during transportation, and the biological reagent tube placement slots in the transport box themselves do not have a limiting function, making the reagent tubes easily damaged during transportation. Therefore, improvements are needed. Utility Model Content

[0004] The purpose of this invention is to solve the problem that reagent tubes are easily damaged during transportation in the prior art, and to propose a low-temperature transport box for biological products.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a low-temperature transport box for biological products, comprising a box body and a box lid, wherein hinges are symmetrically fixedly installed at the connection between the box body and the box lid, a temperature controller is fixedly installed on one side of the box body, test tube placement slots are symmetrically and evenly opened on the inner surface of the box body, circular grooves are symmetrically and evenly opened on the inner surface of the box body, a first spring is symmetrically fixedly installed on the inner wall of the circular groove, a clamping ring is fixedly installed at one end of the first spring, a threaded rod is threadedly connected to the inside of the box lid, an H-shaped pressure plate is rotatably connected to the bottom end of the threaded rod, a limit rod is symmetrically fixedly installed on the top of the H-shaped pressure plate, a limit block is fixedly installed on the top end of the limit rod, and a rotating handle is fixedly installed on the top end of the threaded rod.

[0006] Preferably, a protective pad is fixedly installed on the inner wall of the clamping ring, and the limiting rod is slidably connected to the box cover.

[0007] Preferably, handles are fixedly installed on both sides of the box.

[0008] Preferably, the box body and the box cover are rotatably connected.

[0009] Preferably, a fixed shell is symmetrically fixedly installed on the bottom of the box body. A limit hole is opened through one side of the fixed shell. A locking block is slidably connected inside the fixed shell. An anti-slip pad is fixedly installed on the bottom of the locking block. A circular hole is opened on one side of the locking block. A connecting piece is fixedly installed on the inner surface of the circular hole. A second spring is fixedly installed on the side of the connecting piece away from the circular hole. A limit pin is fixedly installed on the end of the second spring away from the connecting piece.

[0010] Preferably, the limiting pin is slidably connected to the round hole and the limiting hole.

[0011] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0012] 1. In this utility model, the reagent tube is clamped from both sides by the clamping ring, which realizes the horizontal limitation and prevents the reagent tube from shaking in the horizontal direction. At the same time, after the box cover is closed, the H-shaped pressure plate moves downward to press the top of the reagent tube, which also realizes the vertical limitation and prevents the reagent tube from jumping in the vertical direction. In this way, the reagent tube is fixed from multiple directions, ensuring that the reagent tube is in a stable state in the box and effectively preventing the reagent tube from being easily damaged during transportation.

[0013] 2. In this utility model, when the box is placed on a transport vehicle or other flat surface, the anti-slip pad at the bottom of the block can increase the friction between the box and the surface, preventing the box from sliding. At the same time, when the anti-slip pad is worn, it can be easily and quickly replaced without complicated tools or professional maintenance personnel. Users can easily replace the anti-slip pad by following the operating steps. Attached Figure Description

[0021] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0022] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0023] Example 1: As Figures 1-5 As shown, this utility model provides a technical solution: a low-temperature transport box for biological products, including a box body 1 and a box cover 2. Hinges 3 are symmetrically fixedly installed at the connection between the box body 1 and the box cover 2. A temperature controller 4 is fixedly installed on one side of the box body 1. Test tube placement slots 5 are symmetrically and evenly opened on the inner surface of the box body 1. Circular grooves 6 are symmetrically and evenly opened on the inner surface of the box body 1. A first spring 7 is symmetrically fixedly installed on the inner wall of the circular groove 6. A clamping ring 8 is fixedly installed at one end of the first spring 7. A threaded rod 10 is threadedly connected to the inside of the box cover 2. An H-shaped pressure plate 11 is rotatably connected to the bottom end of the threaded rod 10. A limit rod 12 is symmetrically fixedly installed on the top of the H-shaped pressure plate 11. A limit block 13 is fixedly installed on the top end of the limit rod 12. A rotating handle 14 is fixedly installed on the top end of the threaded rod 10. A protective pad 9 is fixedly installed on the inner wall of the clamping ring 8. The limit rod 12 is slidably connected to the box cover 2. Handles 23 are fixedly installed on both sides of the box body 1. The box body 1 and the box cover 2 are rotatably connected.

[0024] In this embodiment, the reagent tube is clamped from both sides by the clamping ring 8, which achieves horizontal limitation and prevents the reagent tube from shaking in the horizontal direction. At the same time, after the box cover 2 is closed, the H-shaped pressure plate 11 moves downward to press the top of the reagent tube, which also achieves vertical limitation and prevents the reagent tube from jumping in the vertical direction. In this way, the reagent tube is fixed from multiple directions, ensuring that the reagent tube is in a stable state inside the box 1, and effectively preventing the reagent tube from being easily damaged during transportation.

[0025] Example 2: Figures 5-6As shown, a fixed shell 15 is symmetrically fixedly installed on the bottom of the housing 1. A limit hole 16 is opened through one side of the fixed shell 15. A locking block 17 is slidably connected inside the fixed shell 15. An anti-slip pad 18 is fixedly installed on the bottom of the locking block 17. A round hole 19 is opened on one side of the locking block 17. A connecting piece 20 is fixedly installed on the inner surface of the round hole 19. A second spring 21 is fixedly installed on the side of the connecting piece 20 away from the round hole 19. A limit pin 22 is fixedly installed on the end of the second spring 21 away from the connecting piece 20. The limit pin 22 is slidably connected to the round hole 19 and the limit hole 16.

[0026] In this embodiment, when the box 1 is placed on a transport vehicle or other flat surface, the anti-slip pad 18 at the bottom of the locking block 17 can increase the friction between the pad and the surface, preventing the box 1 from sliding. At the same time, when the anti-slip pad 18 is worn, it can be easily and quickly replaced without the need for complicated tools or professional maintenance personnel. Users can easily replace the anti-slip pad 18 by following the operating steps.

[0027] The working principle of this embodiment is as follows: When the reagent tube is placed in the test tube placement slot 5, the first spring 7 in the circular slot 6 pushes the clamping ring 8 to move towards the reagent tube. The clamping ring 8 clamps the reagent tube from both sides. The protective pad 9 on the inner wall of the clamping ring 8 can increase the friction between the reagent tube and the test tube, further preventing the reagent tube from shaking. On the other hand, it can avoid scratching or other damage to the reagent tube. After clamping from both sides, the threaded rod 10 is rotated by rotating the handle 14. Since the threaded rod 10 is threadedly connected to the box cover 2, and the limiting rod 12 on the H-shaped pressure plate 11 is slidably connected to the box cover 2, the threaded rod 10 can drive the H-shaped pressure plate 11 to move up and down during the rotation. When the box cover 2 is closed, the threaded rod 10 is rotated downwards, causing the H-shaped pressure plate 11 to move towards the reagent tube and press the top of the reagent tube to prevent the reagent tube from jumping in the vertical direction. When the box 1 is placed on a transport vehicle or other flat surface, the anti-slip pad 18 at the bottom of the locking block 17 increases the friction between the locking block 1 and the surface, preventing the box 1 from sliding. When the anti-slip pad 18 is worn and needs to be replaced, first press the limiting pin 22 to make the limiting pin 22 overcome the elastic force of the second spring 21 and move into the round hole 19. When the limiting pin 22 is completely returned to the round hole 19 and no longer in contact with the limiting hole 16, the locking block 17 is released. After release, the locking block 17 with the worn anti-slip pad 18 can be pulled out from the bottom of the fixed shell 15. After pulling it out, align the new locking block 17 with the anti-slip pad 18 with the bottom of the fixed shell 15. After alignment, press the limiting pin 22 into the round hole 19. After pressing, the locking block 17 can be inserted into the fixed shell 15. After the insertion reaches the limit distance, the rebound force of the second spring 21 will push the limiting pin 22 into the limiting hole 16. After it is pushed in, the replacement is complete.

[0028] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
