DETAILED DESCRIPTION

[0039] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0040] Example 1

[0041] This embodiment is intended to facilitate solving the problem of how to achieve stable positioning of the storage box body 6. Figures 1 to 3 The present invention provides a technical solution: an energy-saving refrigeration system for sample storage and a refrigeration method thereof, comprising a storage box 1 and a docking cabinet door 2, wherein the docking cabinet door 2 is hingedly provided on the side of the storage box 1, and an evaporator 3 is provided on the inner side of the storage box 1;

[0042] Also includes:

[0043] The connecting partition 4 is fixedly connected to the inner wall of the storage box 1, and a limiting mechanism 5 is provided on the side of the connecting partition 4. The limiting mechanism 5 includes a sliding block 501 and a limiting plate 502. The sliding block 501 is embedded in the inner side of the connecting partition 4, and the limiting plate 502 is provided on the outer wall of the sliding block 501. The storage box body 6 is provided on the top of the limiting plate 502. The storage box body 6 has a connecting groove 7 formed inside, and a second spring 8 is provided on the inner side of the storage box body 6. A second ventilation groove 25 is provided on the surface of the connecting partition 4;

[0044] A first blocking plate 9 is provided at the end of the second spring 8, and a first pressing column 10 is provided on one side of the first blocking plate 9, and a first tooth piece 11 is provided at the end of the first pressing column 10, a transmission gear 12 is provided on the side of the first tooth piece 11, and a first groove 13 is provided on the outer side of the first tooth piece 11, and the first groove 13 is provided inside the storage box 1;

[0045] The limiting mechanism 5 further includes a first spring 503, which is disposed at the bottom of the sliding block 501 and is equidistant from the sliding block 501. The sliding block 501 and the limiting plate 502 are integrally formed, and the limiting plate 502 is engaged with the storage box 6. A supporting mechanism 16 is provided on the inner wall of the storage box 6.

[0046] First, use the limit plate 502 set in the connecting partition 4 to position the storage box body 6 on the connecting partition 4, so as to avoid the storage box body 6 from accidentally sliding out and achieve stable positioning of the storage box body 6. Use the bent evaporator 3 to take away the heat inside the storage box body 1 through evaporation, so as to keep the inside of the storage box body at a low temperature at all times. A second ventilation groove 25 is provided on the connecting partition 4, and through grooves are provided on the bottom of the storage box body 6 and the first movable plate 20. The number and size of the through grooves match the number and size of the first ventilation groove 1603 and the second ventilation groove 25, so that cold air can circulate in each storage box body 6, reduce the temperature difference between the storage box bodies 6, and allow the samples stored in the storage box body 6 to be cooled more evenly.

[0047] Example 2

[0048] This embodiment is intended to facilitate solving the problem of how to block the second ventilation groove 25 on the upper and lower connecting partitions 4 when a single storage box body 6 is pulled out. This embodiment is an improvement made on the basis of embodiment 1. For details, please refer to Figures 2 to 7 The first tooth piece 11 is meshed with the transmission gear 12, and the side of the transmission gear 12 is meshed with the second tooth piece 14, and the outer wall of the second tooth piece 14 is provided with a docking column 15, and the supporting mechanism 16 includes a supporting plate 1601, a placement circular hole 1602 and a first ventilation groove 1603, and the surface of the supporting plate 1601 is provided with a placement circular hole 1602, and the side of the placement circular hole 1602 is provided with a first ventilation groove 1603, and the placement circular hole 1602 and the first ventilation groove 1603 are arranged at equal distances;

[0049] The storage box body 6 is provided with a supporting plate 1601 inside, and a plurality of circular holes 1602 for placing are opened on the supporting plate 1601. The arrangement of the circular holes 1602 makes it easy to stably place the sample tubes inside the storage box body 6, and the first ventilation grooves 1603 are opened in the places where the circular holes 1602 are placed, so that the cold air can evenly cool down the samples in the storage box body 6 by using the first ventilation grooves 1603 arranged at equal distances, thereby realizing low-temperature storage. When a single storage box body 6 in the storage case 1 needs to be pulled out, the sliding block 501 on the connecting partition 4 is pulled, and the sliding block 501 drives the limiting plate 502 to slide on the connecting partition 4. When the sliding block 501 moves, it squeezes the first spring 503 at the bottom, so that the limiting plate 502 is separated from the storage box body 6, and the contact locks the storage box body 6;

[0050] When the storage box body 6 is pulled out, the storage box body 6 will release the pressure on the docking column 15. At this time, the restoring elastic force of the second spring 8 in the compressed state in the connecting partition 4 will drive the first blocking plate 9 and the first pressing column 10 to slide in the connecting groove 7. By utilizing the first blocking plates 9 above and below the storage box body 6 to move at the same time, the second ventilation grooves 25 on the upper and lower connecting partitions 4 of the storage box body 6 are staggered and blocked, so as to prevent the cold air on the upper and lower sides from directly contacting the outside when the storage box body 6 is pulled out, thereby effectively reducing the loss of cold air in the storage box body 1, thereby achieving energy-saving effect. When the first pressing column 10 moves, it will also drive the first tooth piece 11 to move, and the second tooth piece 11 will move. A tooth piece 11 is connected to the second tooth piece 14 through a transmission gear 12, thereby realizing the relative movement of the first tooth piece 11 and the second tooth piece 14. When the second tooth piece 14 moves, it will drive the docking column 15 to move, so that when the storage box body 6 is placed in the storage box body 1 again later, the first blocking plate 9 is automatically driven to slide by pressing the docking column 15, opening the circulation of the second ventilation groove 25 on the connecting partition 4, and utilizing the second spring 8 set in a compressed state on the side of the first blocking plate 9, when contacting the lock of the storage box body 6, the reset elastic force of the second spring 8 will drive the storage box body 6 to automatically slide outward a certain distance, so as to facilitate the removal of the storage box body 6.

[0051] Example 3

[0052] This embodiment is intended to facilitate solving the problem of how to reduce the convection between the internal cold air and the external ambient air during the process of extracting the storage box 6. This embodiment is an improvement made on the basis of embodiment 1. For details, please refer to Figure 2 、 Figure 5 and Figure 7 , the supporting plate 1601 is fixedly connected to the storage box body 6, and a first air bag 17 is provided inside the storage box body 6, and a second blocking plate 18 is fitted on the side of the first air bag 17, and a second pressure column 19 is provided on the outer wall of the second blocking plate 18, and a first movable plate 20 is provided on the top of the supporting plate 1601, and an elastic strip 21 is fitted on the surface of the first movable plate 20, and the elastic strip 21 is adhesively connected to the storage box body 6, and a third pressure column 22 passes through the interior of the first movable plate 20, and a third blocking plate 23 is fixedly connected to the end of the third pressure column 22, and a second air bag 24 is provided on the side of the third blocking plate 23, and a through groove is provided on the surface of the third blocking plate 23 and the first movable plate 20, and the first movable plate 20 is slidably connected to the storage box body 6, and a second groove 26 is provided on the inner side of the storage box body 6, and a docking rod 27 is provided on the side of the storage box body 6;

[0053] When the storage box body 6 is being pulled out, the second pressure post 19 on the storage box body 6 and the third pressure post 22 on the first movable plate 20 will separate from the storage box body 1, and the contact will squeeze the second pressure post 19 and the third pressure post 22. At this time, the first airbag 17 in the compressed state in the storage box body 6 will drive the second blocking plate 18 to move, so that the second blocking plate 18 will offset and block the through groove that is identical to the second ventilation groove 25 on the bottom of the storage box body 6. The restoring elastic force of the second airbag 24 in the first movable plate 20 will drive the third blocking plate 23 to slide inside the first movable plate 20, and the through groove that is identical to the second ventilation groove on the first movable plate 20 will be offset and blocked by the third blocking plate 23, so as to seal the storage box body 6 and reduce convection with the outside air.

[0054] When it is necessary to take out the sample tube in the storage box body 6, the first movable plate 20 is pushed to slide the first movable plate 20 in the storage box body 6, making it more convenient to take out and place the sample tube. An elastic strip 21 is provided between the first movable plate 20 and the storage box body 6. The elastic strip 21 is used to increase the tightness of the connection to prevent the first movable plate 20 from accidentally slipping off. When the storage box body 6 is inserted into the storage box body 1, the second pressure column 19 and the third pressure column 22 will be squeezed at the same time, thereby driving the second blocking plate 18 and the third blocking plate 23 at the same time to open the cold air circulation channel.

[0055] Example 4

[0056] This embodiment is intended to facilitate the solution of the problem of how to recover the cold air in the storage box 6. This embodiment is an improvement made on the basis of embodiment 1. For details, please refer to Figure 2 and Figures 8 to 10 A blocking piece 28 is provided at the end of the docking rod 27, and the blocking piece 28 is arranged in the center of a circle, and a third spring 29 is provided on the side of the blocking piece 28, and a suction airbag 30 is provided on the outside of the third spring 29, and an elastic ring 31 is provided on the outer wall of the suction airbag 30, and the outer surface of the elastic ring 31 is in contact with the outer surface of the storage box body 6, and a docking piece 32 is provided on the outer wall of the suction airbag 30, and the end of the docking piece 32 is fixedly connected to the second movable plate 33, and a positioning block 34 is provided on the outer wall of the second movable plate 33, and a fourth spring 35 is provided on the side of the second movable plate 33;

[0057] When the storage box body 6 is installed inside the storage box body 1, the storage box body 6 will squeeze the docking rod 27 and the suction airbag 30, so that the suction airbag 30 is in a compressed state, and the left and right sides of the suction airbag 30 are both made of hard disc-shaped material (it should be noted that the hard disc material can be made by adhering hard material at both ends of an ordinary airbag to form an integral process, and the hard material can be selected according to actual needs), so that the suction airbag 30 can slide normally in the storage box body 1, and the suction airbag 30 and the storage box body 1 are fixedly connected, so that the suction airbag 30 can move normally, and an elastic ring 31 is provided on the top of the suction airbag 30, and the elastic ring 31 is made of elastic material to make the connection between the two more tightly, and when the two are docked, the storage box body 6 will squeeze the docking rod 27, and the docking rod 27 drives the blocking piece 28 to slide in the suction airbag 30, thereby opening the flow channel of the suction airbag 30, so that the gas in the storage box body 6 can enter the suction airbag 30 through the second groove 26;

[0058] When the storage box body 6 is drawn out, the fourth spring 35 in the compressed state in the storage box body 1 drives the second movable plate 33 and the positioning block 34 to slide in the storage box body 1. The fourth spring 35 is used to make the elastic ring 31 of the suction airbag 30 tightly connected to the storage box body 6. At this time, the compressed suction airbag 30 will reset to suck the cold air in the storage box body 6, so as to recover the cold air in the storage box body 6. The suction airbag 30 is provided with multiple pieces to improve the cold air recovery effect. As the storage box body 6 continues to move, the storage box body 6 will be separated from the elastic ring 31. At this time, the third spring 29 drives the blocking piece 28 to move, blocking the outlet of the suction airbag 30 to prevent the gas in the suction airbag 30 from accidentally flowing out.

[0059] When the storage box body 6 is placed into the storage box body 1, the storage box body 6 will squeeze the docking rod 27, drive the blocking piece 28 to move, and open the circulation channel of the suction airbag 30. As the storage box body 6 moves inward, the suction airbag 30 and the fourth spring 35 will be squeezed again, and the gas inside the suction airbag 30 will flow back into the storage box body 6 again, further improving its energy-saving effect.

[0060] Example 5

[0061] For this example, please refer to Figures 1 to 10 , including the following steps:

[0062] S1: First, the cold air generated by the evaporator 3 in the storage box 1 is used to maintain the storage box 1 at a low temperature, so as to store the test tubes placed in the storage box 6 at a low temperature;

[0063] S2: The storage box body 6 is provided with a circular hole 1602 for positioning the test tubes, and there are multiple circular holes 1602, which are convenient for separating and stably placing multiple test tubes;

[0064] S3: A first ventilation groove 1603 is provided on the side of the circular hole 1602, and a second ventilation groove 25 is provided on the connecting partition 4. The first ventilation groove 1603 and the second ventilation groove 25 allow the cold air in the storage box 1 to circulate between the various storage boxes 6, so that the test tubes in the storage boxes 6 are cooled more evenly.

[0065] S4: When a single storage box 6 is pulled out from the connecting partition 4, the restoring elastic force of the first airbag 17 in the storage box 6 drives the second blocking plate 18 to move, and the restoring elastic force of the second airbag 24 drives the third blocking plate 23 to move, thereby sealing the pulled-out single storage box 6 and utilizing the suction airbag 30 to extract the cold air in the storage box 6. This facilitates the subsequent reinsertion of the storage box 6 into the storage box 1 by squeezing the suction airbag 30, allowing the cold air in the suction airbag 30 to re-enter the storage box 1, thereby achieving an energy-saving effect.

[0066] S5: When the storage box body 6 is separated from the connecting partition 4, the first spring 503 in the upper and lower connecting partitions 4 drives the reset elastic force to drive the first blocking plate 9 to move, blocking the second ventilation groove 25 opened on the connecting partition 4, reducing the loss of cold air in the storage box body 6 that has not been pulled out, and further achieving the energy-saving effect.
