Technical realization elements:

4.1. Technical problems to be solved

5. In view of the problems in the prior art, the purpose of the present utility model is to provide an ultra-low temperature refrigerator sealing device, which can be directly replaced and disassembled when the sealing mechanism is damaged, improving work efficiency, and keeping it after replacement The original tightness.

6.2. Technical solution

7. In order to solve the above problems, the present utility model adopts the following technical solutions.

8. A sealing device for an ultra-low temperature refrigerator, comprising a box body, the upper right end of the box body is rotatably connected with a rotating shaft, the outer end of the rotating shaft is fixedly connected with a plurality of evenly distributed sealed doors, and the outer ends of the plurality of sealed doors are all fixedly connected There is a display, a plurality of evenly distributed placement grooves are excavated in the box body, a storage box is slidably connected in the placement groove, the sealed door is located on the outside of the storage box, and two sliding grooves are cut out at the left end of the sealed door, A sealing mechanism is slidably connected to the sliding groove, the sealing mechanism is connected with the storage box, a groove is cut at the outer end of the sealing mechanism, a rotating rod is rotatably connected in the groove, and the right end of the rotating rod is fixedly connected There is a handle, the outer end of the sealed door is cut with a buckle groove, and a buckle is fixedly connected to the buckle groove. The buckle is matched with the handle. Replacement and disassembly can improve work efficiency and maintain the original sealability after replacement.

9. Further, the outer end of the sealed door is fixedly connected with a handle, the handle is located on the left side of the display, and the surface of the handle is provided with anti-skid patterns. When the sealed door is pulled, the handle can be used to increase the friction when pulling. To make it more convenient.

10. Further, a slot is excavated at the left end of the sealing door, the slot is located on the lower side of the sliding groove, and a fastening plate is inserted in the slot, and the fastening plate is in contact with the sealing mechanism. After the sealing mechanism is slid into the sliding groove, the sealing mechanism can be fastened by inserting the fastening plate into the slot.

11. Further, a spring is fixedly connected to the slot, and the spring is fixedly connected to the fastening plate. When the fastening plate is inserted into the slot, the sealing door may be loosened due to the opening and closing of the sealing door. Therefore, the elasticity of the spring makes the spring tight. The fixed plate further tightens the sealing mechanism, and at the same time makes the spring not easy to loosen.

12. Further, a first magnetic block is fixedly connected to the right end of the storage box, a second magnetic block is fixedly connected in the sealing mechanism, and the second magnetic block is attracted to the first magnetic block. When the box is in contact and the box is sealed, the first magnetic block and the second magnetic block can attract each other to increase the tightness between the two.

13.3. Beneficial effects

14. Compared with the prior art, the advantages of this utility model are:

15. (1) This solution can realize that when the sealing mechanism is damaged, it can be directly replaced and disassembled, which improves work efficiency and maintains the original sealing performance after replacement.

16. (2) The outer end of the sealed door is fixedly connected with a handle. The handle is located on the left side of the display. The surface of the handle is provided with anti-skid patterns. When the sealed door is pulled, the handle can be used to increase the friction during pulling, making it more convenient.

17.(3) A slot is excavated at the left end of the sealing door. The slot is located on the lower side of the chute. A fastening plate is inserted in the slot. The fastening plate is in contact with the sealing mechanism. After the sealing mechanism slides into the chute , The sealing mechanism can be fastened by inserting the fastening plate into the slot.

18.(4) A spring is fixedly connected in the slot, and the spring is fixedly connected to the fastening plate. When the fastening plate is inserted into the slot, it may loosen when opening and closing the sealed door. Therefore, the elasticity of the spring makes the fastening plate to seal The mechanism is further tightened, and at the same time, the spring is not easy to loosen.

19. (5) A first magnetic block is fixedly connected to the right end of the storage box, and a second magnetic block is fixedly connected to the sealing mechanism. The second magnetic block is attracted to the first magnetic block. When the body is sealed, the first magnetic block and the second magnetic block can attract each other to increase the tightness between the two.
