However, the power of existing chemical storage boxes is limited, and the storage cavity of existing storage boxes is relatively large to accommodate reagent tubes of different sizes. This results in some smaller reagent tubes only occupying part of the space in the storage cavity when placed in the storage cavity, but the entire storage cavity needs to be maintained at a suitable temperature, which greatly increases the power consumption of the storage box and poses a serious challenge to the battery life of the storage box. Furthermore, when the existing storage box is opened and closed to take out the reagent tube, each storage cavity will come into contact with the outside world, causing the cold air in the storage cavity to be lost, greatly increasing the power consumption of the equipment. Summary of the invention

[0014] The present invention has the following advantages: the first airbag is driven to move downward by the multi-stage electric push rod, and then the middle part of the first airbag contacts the upper end of the reagent tube, and the upper and lower ends of the reagent tube are clamped in cooperation with the sponge pad; thus, reagent tubes of different sizes are fixed in the storage cavity; at the same time, the storage cavity is divided into upper and lower parts by the first fixing block and the first airbag, so only the area below the first fixing block storing the reagent tube needs to be refrigerated and temperature controlled; the refrigeration space is greatly reduced, thereby reducing the power consumption of the equipment and increasing the battery life of the equipment; At the same time, the air pump in the storage box is used to inflate the third airbag, which is squeezed upward and then pushes the reagent tube upward and out.

[0021] It also includes a second connecting tube 107 and a second airbag 108; the second airbag 108 is fixedly connected to the outer side of the first fixed block 102; the second airbag 108 is connected to the air pump in the storage box 1 via a second connecting tube 107, and the second connecting tube 107 is an elastic tube. In the initial state, the second airbag 108 is in a contracted state, and at this time, the second airbag 108 does not fit the inner wall of the storage cavity 1002; therefore, the first fixed block 102 does not contact the inner wall of the storage cavity 1002.

[0022] The lifting assembly includes a sponge pad 201 and a third airbag 202 ; the third airbag 202 is fixedly connected to the bottom of the storage cavity 1002 ; the third airbag 202 is connected to the air pump in the storage box 1 ; and the sponge pad 201 is fixedly connected to the upper side of the third airbag 202 .

[0023] It also includes a sealing curtain 109; a sealing curtain 109 is fixedly connected between each second fixed block 203 and the corresponding first fixed block 102 and the corresponding sponge pad 201, and the sliding groove 1003 and the storage cavity 1002 are separated by the sealing curtain 109, so as to further reduce the refrigeration space and improve the battery life.

[0024] The second fixing block 203 is provided with four through slots 20301 .

[0025] It also includes a limiting block 105 ; the upper side of each storage cavity 1002 is fixedly connected to the limiting block 105 .

[0026] A sealing ring 205 is also included; the sealing ring 205 is arranged on the cover plate of the storage box 1.

[0027] The working principle of the above embodiment is as follows: First, Figure 1 The side where the storage box 1 is marked is the right side. First, the worker opens the cover of the storage box 1, and then puts the reagent tube 555 containing the chemical agent into the storage cavity 1002. In this process, Figure 2-Figure 6As shown: in the initial state; the first airbag 103 is in a contracted state, so the through groove in the middle of the first airbag 103 is larger, so the worker can smoothly pass the reagent tube 555 through the first airbag 103 and then insert it into the storage cavity 1002. It should be noted that in the initial state, the multi-stage electric push rod 101 is in an extended state. At this time, the first fixing block 102 is located on the upper side of the storage cavity 1002, so the worker needs to completely insert the reagent tube 555 into the lower side of the first airbag 103. During this process, the reagent tube 555 will pass through the clamping ring 204 made of silicone rubber; the clamping ring 204 will be squeezed and contracted by the outer wall of the reagent tube 555, and at the same time, the clamping ring 204 will generate an expansion restoring force to clamp the reagent tube 555, and then fix the reagent tube 555 through the clamping ring 204; when the reagent tube 555 is inserted into the lower side of the first airbag 103, At this time, the bottom of the longest reagent tube 555 just touches the upper part of the sponge pad 201; the bottoms of the reagent tubes 555 of other lengths will not touch the sponge pad 201; then the worker starts the control system in the storage box 1 through the control panel 1001, controls the air pump in the storage box 1 to inject gas into the corresponding first connecting pipe 106, and then injects the gas into the first airbag 103 through the first connecting pipe 106; then the first airbag 103 is inflated, and the middle groove is truncated. At this time, the upper side diameter of the middle groove of the first airbag 103 is smaller than the diameter of the reagent tube 555; then the multi-stage electric push rod 101 will drive the first fixed block 102 and the second fixed block 203 to move downward, and then drive the reagent tube 555 to move downward, so that the bottoms of the reagent tubes 555 of different lengths can contact the sponge pad 201; After the reagent tube 555 contacts the sponge pad 201, the third airbag 202 is in a contracted state in the initial state and can no longer contract, so the sponge pad 201 cannot move downward. Therefore, as the telescopic end of the multi-stage electric push rod 101 contracts, the reagent tube 555 cannot move downward at this time, and the first fixed block 102 and the second fixed block 203 will continue to move downward, thereby driving the first airbag 103 to move downward, and then the middle part of the first airbag 103 will contact the upper end of the reagent tube 555, and cooperate with the sponge pad 201 to clamp the upper and lower ends of the reagent tube 555; thereby fixing the reagent tubes 555 of different sizes in the storage cavity 1002; After the above operation, the first fixed block 102 will divide the storage cavity 1002 into two parts, the upper and lower parts, and the reagent tube 555 is fixed under the first fixed block 102; then the temperature control device in the storage box 1 is started, and the cold air enters the storage cavity 1002 through the air inlet pipe 3 to cool the reagent tube 555 fixed under the first fixed block 102, and at the same time, the exhaust fan in the storage box 1 is started to discharge the hot air generated during the heat exchange under each first fixed block 102; thereby realizing the circulation of cold air; improving the refrigeration storage effect, at the same time, the worker can control the control system in the storage box 1 through the control panel 1001 to adjust the refrigeration temperature in each storage cavity 1002 respectively, and then adjust the storage cavity 1002 to a suitable storage temperature according to the different chemical properties of the medicine; greatly improving the storage effect of the equipment; and the first fixed block 102 divides the storage cavity 1002 into two parts, the upper and lower parts, so it is only necessary to refrigerate and control the temperature of the area below the first fixed block 102; greatly reducing the refrigeration space, thereby reducing the power consumption of the equipment and increasing the battery life of the equipment; when When the worker needs to open the storage box 1 to take the reagent tube 555, the air pump in the storage box 1 is controlled to inhale air into the corresponding first connecting tube 106, and then the first airbag 103 contracts, thereby releasing the clamping of the upper end of the reagent tube 555; then the air pump in the storage box 1 inflates the third airbag 202, and the third airbag 202 squeezes upward to squeeze and push out the reagent tube 555, and at the same time, the corresponding multi-stage electric push rod 101 is also pushed upward to reset, thereby driving the first fixed block 102 and the second fixed block 203 to move upward to reset. ; Then the corresponding reagent tube 555 is pushed out through the first airbag 103, and the worker can take out the reagent tube 555. During this process, the first fixed block 102 in the remaining storage cavity 1002 continues to seal the storage cavity 1002; the first airbag 103 continues to clamp the reagent tube 555, and thus will not affect the storage of the remaining reagent tubes 555, and when the first fixed block 102 moves upward and resets, the first fixed block 102 is limited by the limit block 105 to prevent the first fixed block 102 from extending upward from the storage cavity 1002.

[0028] Furthermore, in order to prevent the loss of cold air under the first fixed block 102, the first fixed block 102 must be in contact with the inner wall of the storage chamber 1002 to seal the storage chamber 1002. However, after the first fixed block 102 is in contact with the inner wall of the storage chamber 1002, it is difficult for the multi-stage electric push rod 101 to drive the first fixed block 102 to move up and down, and the first fixed block 102 will also produce friction with the inner wall of the storage chamber 1002 during the movement, resulting in the subsequent first fixed block 102 being unable to fit with the inner wall of the storage chamber 1002, affecting the sealing of the storage chamber 1002 by the first fixed block 102. Therefore, in the initial state, the second airbag 108 is in a contracted state, and the second airbag 108 is not in contact with the inner wall of the storage chamber 1002. The push rod 101 can drive the first fixed block 102 to move up and down; when the air inlet pipe 3 inputs cold air to the storage chamber 1002, the air pump in the storage box 1 is used to inflate the second connecting pipe 107, and then the second air bag 108 is inflated. After the second air bag 108 is inflated, it will fit with the inner wall of the storage chamber 1002, and then the storage chamber 1002 is sealed. Then, through this method, when the first fixed block 102 moves, the second air bag 108 does not contact the inner wall of the storage chamber 1002, so that the first fixed block 102 can move up and down normally; when the first fixed block 102 needs to be sealed; the second air bag 108 will fit with the inner wall of the storage chamber 1002 to seal the storage chamber 1002, and the first fixed block 102 is made of heat-insulating material, which can effectively prevent the loss of cold air under the first fixed block 102; Furthermore, although the second fixed block 203 is matched with the inner wall gap of the storage cavity 1002, the cold air can pass through the second fixed block 203; however, in order to improve the cooling effect, four through grooves 20301 are opened on the second fixed block 203. The cold air entering the lower part of the second fixed block 203 can reach the upper side of the second fixed block 203 through the through grooves 20301, and then quickly cool the space below the first fixed block 102, thereby improving the cooling effect and making the temperature of the storage cavity 1002 more stable and uniform.

[0029] On the basis of the above technical effects, the present invention also has the following advantages: The clamping ring 204 is hollow and made of flexible silicone material with good elasticity. After being squeezed by the reagent tube 555 and contracted, it will generate a restoring stretching force to clamp the reagent tube 555. The flexible silicone has good high and low temperature resistance and a long service life. The cover plate of the storage box 1 is provided with a sealing ring 205; the sealing effect of the cover plate is improved by the sealing ring 205 The sliding groove 1003 and the storage cavity 1002 are separated by the sealing curtain 109, so as to further reduce the refrigeration space and improve the battery life.

[0030] Example 2 On the basis of Example 1, Figure 1 and Figure 2 As shown, a rubber pad 206 is also included; the rubber pad 206 is fixedly connected to the bottom of the storage box 1.

[0031] The storage box 1 also includes a shoulder strap 207 ; the shoulder strap 207 is fixedly connected to the storage box 1 .

[0032] The working principle of the above embodiment is as follows: Because the storage box 1 is provided with many parts such as a control system, an air pump, a temperature control device and an exhaust fan, the storage box 1 is heavy. Therefore, when the worker places the storage box 1, the storage box 1 will generate a large impact force when it falls to the ground, causing the reagent tube 555 in the storage box 1 to be at risk of rupture. Therefore, a rubber pad 206 is provided at the bottom of the storage box 1; when the worker puts down the storage box 1, the rubber pad 206 reduces the impact force when the storage box 1 falls to the ground, thereby protecting the reagent tube 555 in the storage box 1; and because the storage box 1 is heavy, a shoulder strap 207 is provided on the storage box 1. When the worker is too tired to carry it by hand, the storage box 1 can be carried on the shoulder through the shoulder strap 207, so that the worker can walk with the storage box 1.

[0033] The embodiments of the present invention are described in detail above with reference to the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made within the knowledge scope of those skilled in the art without departing from the spirit of the present invention.
