[0002] Biomedical cold storage facilities are widely used for the storage of various pharmaceuticals, vaccines, blood, plasma, reagents, semen, stem cells, bone marrow, biological products, and other medical supplies. When storing biomedical supplies, the internal temperature of the cold storage facility generally needs to be below -70 degrees Celsius. As the service life of the insulated door extends, corrosion and rust will appear on the outer surface of the insulated door. When corrosion and rust appear on the insulated door, it will affect the performance of the insulated door and shorten its service life.

[0003] A search revealed a patent document with publication number CN218054323U that discloses a semi-recessed door with good corrosion resistance. This utility model discloses a semi-recessed door with good corrosion resistance, including a door body with a handle on the front. The door body includes a base layer, an insulation layer inside the base layer, a reinforcing layer fixedly connected to the outer surface of the base layer, a fireproof layer fixedly connected to the outer surface of the reinforcing layer, a frost-resistant layer fixedly connected to the outer surface of the fireproof layer, a first anti-corrosion layer fixedly connected to the outer surface of the frost-resistant layer, and a second anti-corrosion layer fixedly connected to the outer surface of the first anti-corrosion layer. This utility model, through the combined use of the door body, base layer, insulation layer, reinforcing layer, fireproof layer, frost-resistant layer, first anti-corrosion layer, second anti-corrosion layer, toughness layer, wear-resistant layer, and handle, solves the problem of existing cold storage semi-recessed doors having poor corrosion resistance, being easily damaged by the environment, resulting in resource waste and property loss, and failing to meet user needs.

[0004] The above-mentioned technical solution lacks a buffer device during use, resulting in poor buffering effect on the cold storage door, making the cold storage door easily damaged and with a short service life.

[0005] Therefore, it is necessary to invent a safety and heat insulation mechanism for biomedical cold storage doors to solve the above problems. Utility Model Content

[0007] To achieve the above objectives, this utility model provides the following technical solution: a safety and heat insulation mechanism for a biomedical cold storage door, comprising an insulated door body, a buffer protection mechanism provided on the surface of the insulated door body, the buffer protection mechanism including a linkage handle hinged to the outer wall of the insulated door body, a threaded rod rotatably connected to the center of the linkage handle, the threaded rod penetrating and extending to the side of the insulated door body away from the linkage handle, a threaded block threadedly connected to the outer wall of the threaded rod, two sets of sliding rods slidably connected inside the threaded block, the sliding rods being fixedly connected to the inner wall of the insulated door body, a telescopic rod fixedly connected to the side of the threaded block away from the linkage handle, a buffer spring sleeved on the outer wall of the telescopic rod, and a buffer sleeve fixedly connected to the side of the telescopic rod and the buffer spring away from the linkage handle, thereby improving the buffering capacity of the structure and preventing damage to the insulated door body through the cooperation of the buffer spring, the telescopic rod, and the buffer sleeve.

The heat insulation capacity of the insulated door body is increased by the composite heat insulation mechanism, and the impact resistance is further improved by the cooperation between the mounting base and the buffer sleeve.

[0009] Preferably, one end of the insulated door is hinged to the cold storage body, the interior of the cold storage body has a door groove, and the mounting base is fixedly connected to the surface of the door groove, providing space for the operation of the buffer protection mechanism through the door groove.

[0010] Preferably, a number of sets of sealing rubber are fixedly connected to the surface of the door groove. The cross-section of the sealing rubber is U-shaped.

[0024] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0025] This utility model provides, for example Figure 1-5 The diagram illustrates a safety and heat insulation mechanism for a biomedical cold storage door, comprising an insulated door body 1. A buffer protection mechanism 2 is provided on the surface of the insulated door body 1. The buffer protection mechanism 2 includes a linkage handle 201 hinged to the outer wall of the insulated door body 1. A threaded rod 202 is rotatably connected to the center of the linkage handle 201. The threaded rod 202 penetrates and extends to the side of the insulated door body 1 away from the linkage handle 201. A threaded block 204 is threadedly connected to the outer wall of the threaded rod 202. Two sets of sliding rods 203 are slidably connected inside the threaded block 204. The sliding rods 203 are fixedly connected to the inner wall of the insulated door body 1. A telescopic rod 20 is fixedly connected to the side of the threaded block 204 away from the linkage handle 201. 5. A buffer spring 210 is sleeved on the outer wall of the telescopic rod 205. A buffer sleeve 206 is fixedly connected to the side of the telescopic rod 205 and the buffer spring 210 away from the linkage handle 201. The buffer spring 210, the telescopic rod 205 and the buffer sleeve 206 work together to improve the buffering capacity of the structure and prevent damage to the insulated door 1. A composite heat insulation mechanism 101 is fixedly connected to the inner wall of the insulated door 1. The composite heat insulation mechanism 101 has multiple layers of composite heat insulation, including a vacuum layer, aerogel and high-density polyurethane foam. A top contact rod 207 is provided on one side of the buffer sleeve 206. The side of the top contact rod 207 away from the buffer sleeve 206 is fixedly connected to... The insulated door 1 has a mounting base 208, which increases the insulation capacity of the insulated door 1 through the composite insulation mechanism 101, and further improves the impact resistance through the cooperation of the mounting base 208 and the buffer sleeve 206. A cold storage body 5 is hinged to one end of the insulated door 1. A door groove 102 is provided inside the cold storage body 5. The mounting base 208 is fixedly connected to the surface of the door groove 102, providing space for the buffer protection mechanism 2 to operate. Several sets of sealing rubber 209 are fixedly connected to the surface of the door groove 102. The sealing rubber 209 has a U-shaped cross-section. As the insulated door 1 closes, the air inside the U-shaped structure of the sealing rubber 209 is squeezed out, and the sealing rubber 209 and the insulated door 1... A vacuum is formed between the sealing rubber 209 and the insulated door body 1, which is firmly adsorbed to the bottom surface of the insulated door body 1 to improve the sealing performance, avoid cold leakage, and save energy. The cooperation between the sealing rubber 209 and the insulated door body 1 improves the sealing performance of the insulated door body 1 and avoids cold leakage. Through the cooperation between the insulated door body 1 and the buffer protection mechanism 2, the rotation of the linkage handle 201 realizes the rotation of the threaded rod 202, which in turn cooperates with the sliding rod 203 to realize the movement of the threaded block 204. The threaded block 204 is used to adjust the range of motion of the telescopic rod 205 and the buffer sleeve 206. The cooperation between the top contact rod 207 and the buffer sleeve 206 prevents the sealing rubber 209 and other parts from being damaged by collision, thereby improving the service life of the insulated door body 1.

[0026] Refer to the instruction manual appendix Figure 1-5 A lock box 3 is fixedly connected to the surface of the insulated door 1, and a heating element 9 is fixedly connected to the top of the lock box 3. A threaded rotating rod 6 is threadedly connected inside the lock box 3. A limit rod 7 is rotatably connected to the inner end of the threaded rotating rod 6. The heating element 9 prevents the threaded rotating rod 6 from freezing. A reinforcing box 4 is provided on one side of the limit rod 7 and is fixedly connected to the surface of the cold storage body 5. An extrusion block 8 is fixedly connected inside the reinforcing box 4. The shape of the extrusion block 8 corresponds to that of the reinforcing box 4. The sealing performance is improved by the cooperation between the limit rod 7 and the extrusion block 8. Through the cooperation of the lock box 3, the reinforcing box 4 and other parts, the threaded rotating rod 6 is rotated to slide the limit rod 7. Through the cooperation between the limit rod 7 and the reinforcing box 4, the limit rod 7 enters the interior of the reinforcing box 4 and is squeezed by the extrusion block 8. The sealing performance between the insulated door 1 and the cold storage body 5 is improved by the joint limiting of the threaded rotating rod 6 and the extrusion block 8.

[0027] The working principle of this practical application is as follows:

[0028] Refer to the instruction manual appendix Figure 1-5 When it is necessary to close the cold storage for biomedical supplies with an operating temperature of -70 degrees Celsius, rotate the insulated door 1 so that it rotates along the connection between the insulated door 1 and the lock box 3. During the rotation, the top contact rod 207 contacts the top contact rod 207. The elastic force of the buffer spring 210, combined with the extension and retraction of the telescopic rod 205, prevents the insulated door 1 from directly contacting the door groove 102, thereby preventing the impact on the surface of the insulated door 1 from damaging the sealing rubber 209 and the internal parts of the insulated door 1. Then, rotate the linkage handle 201 so that the threaded rod 202 rotates and drives the threaded block 204 to gradually retract along the sliding rod 203, thereby gradually closing the insulated door. The gap between body 1 and door groove 102, and when telescopic rod 205 and threaded block 204 return to the origin, rotate threaded rotating rod 6 to realize the sliding of limit rod 7. Through the cooperation of limit rod 7 and reinforcement box 4, limit rod 7 enters the interior of reinforcement box 4 and is squeezed by compression block 8. The joint limiting of threaded rotating rod 6 and compression block 8 improves the sealing performance between insulation door body 1 and cold storage body 5. When it is necessary to open insulation door body 1, the above operation is repeated in reverse. The pressure is slowly released by the elastic force of buffer spring 210 to reduce impact, thereby ensuring that the cold storage can maintain a state of minus seventy degrees and avoid damage to biomedical products due to structural damage to the cold storage and the resulting cold leakage.

[0029] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
