[0025] The following will be combined with the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] Example 1

[0027] A preferred embodiment of a portable blood storage device provided by the utility model is as follows Figures 1 to 5 As shown: A portable blood storage device, including a refrigerator 1, the top of the refrigerator 1 is connected to a box cover 2 by a hinge, the top of the box cover 2 is fixedly connected to a handle 3, the surface of the refrigerator 1 is provided with a display screen 4, the back of the display screen 4 is connected to a temperature sensor 5, the inner wall of the refrigerator 1 is provided with a test tube groove 6, the bottom of the refrigerator 1 is fixedly connected to a support leg 7, the bottom of the refrigerator 1 is provided with a moving mechanism 8 on the side of the support leg 7, the back of the refrigerator 1 is fixedly connected to an adjusting rod 9, the inner wall of the adjusting rod 9 is fitted with a handle 10, and the side of the handle 10 is penetrated by bolts and nuts 11.

[0028] When the staff adjusts the height to a suitable level, the bolt and nut 11 can be passed through the adjustment holes on the handle 10 and the adjustment holes on the side of the adjustment rod 9, and the bolt and nut 11 can be tightened to fix the handle 10 at the current position, thereby achieving the purpose of adjusting the height of the handle 10.

[0029] Example 2

[0030] Based on Example 1, a preferred embodiment of a portable blood storage device provided by the present invention is as follows: Figures 1 to 5 As shown: the moving mechanism 8 includes a screw rod 81, a slider 82, a transmission plate 83, a lifting plate 84 and a roller 85. The bottom of the refrigerator 1 is located on the side of the support leg 7 and is rotatably connected to the screw rod 81. The surface of the screw rod 81 is threadedly connected to the slider 82. The surface of the slider 82 is rotatably connected to the transmission plate 83. The surface of the transmission plate 83 is rotatably connected to the lifting plate 84. The bottom of the lifting plate 84 is fixedly connected to the roller 85.

[0031] In this embodiment, the surface of the screw rod 81 is provided with two sets of threads in opposite directions, and the two sets of threaded surfaces of the screw rod 81 are meshed with sliders 82. Since the surface of the screw rod 81 is provided with two sets of threads in opposite directions, and the two sets of sliders 82 are respectively meshed with them, when the screw rod 81 rotates, it will drive the two sets of sliders 82 to slide relative to each other and move away from each other.

[0032] In this embodiment, four groups of transmission plates 83 are provided, and the four groups of transmission plates 83 are all inclined. Because the four groups of transmission plates 83 are respectively rotationally connected to the two groups of sliders 82, and the four groups of transmission plates 83 are inclined, when the sliders 82 slide, thrust is applied to the four groups of transmission plates 83, causing the four groups of transmission plates 83 to swing downward.

[0033] In this embodiment, two groups of lifting plates 84 are provided, and two groups of rollers 85 are fixedly connected to the bottom of each group of lifting plates 84. Because the two groups of lifting plates 84 are respectively rotatably connected to the four groups of transmission plates 83, when the transmission plates 83 swing, the two groups of lifting plates 84 will slide downward along the surface of the support legs 7. At this time, the four groups of rollers 85 fixedly connected to the two groups of lifting plates 84 will drop accordingly. When the rollers 85 drop to contact the ground and lift the support legs 7, the cold storage box 1 can be pulled by the handle 10. At this time, the cold storage box 1 will move through the rollers 85, thereby achieving the purpose of easy carrying.

[0034] In this embodiment, a circular groove matching the support foot 7 is provided on the top of the lifting plate 84, and the support foot 7 passes through the circular groove on the top of the lifting plate 84 and is slidably connected with the lifting plate 84. Because the support foot 7 passes through the circular groove on the top of the lifting plate 84, when the lifting plate 84 is lifted or lowered, it will be lifted or lowered along the surface of the support foot 7. At this time, the support foot 7 will play a certain limiting role on the lifting plate 84, so that the lifting plate 84 can be lifted or lowered vertically.

[0035] The working principle and use process of the utility model are as follows: first, put the blood sample test tube into the test tube slot 6, then close the box cover 2 and lock it, then the refrigerator can be carried by the handle 3. By setting the temperature sensor 5 and the display screen 4, the temperature sensor 5 will monitor the temperature inside the refrigerator 1 at any time and display it on the display screen 4. When it is inconvenient to carry it by the handle 3, the screw rod 81 can be manually rotated counterclockwise. Since the surface of the screw rod 81 is provided with two sets of threads in opposite directions, and the two sets of sliders 82 are respectively engaged with it, when the screw rod 81 rotates, the two sets of sliders 82 will slide relative to each other and move away from each other. Because the four sets of transmission plates 83 are respectively engaged with the two sets of transmission plates 83, the four sets of transmission plates 83 are respectively engaged with the two sets of transmission plates 83. The sliders 82 are rotatably connected, and the four transmission plates 83 are inclined, so when the sliders 82 slide, thrust is applied to the four transmission plates 83, causing the four transmission plates 83 to swing downward. Because the two lifting plates 84 are rotatably connected to the four transmission plates 83, respectively, when the transmission plates 83 swing, the two lifting plates 84 are driven to slide downward along the surface of the support legs 7. At this time, the four rollers 85 fixedly connected to the two lifting plates 84 will drop accordingly. When the rollers 85 drop to contact the ground and lift the support legs 7, the refrigerator 1 can be pulled by the handle 10. At this time, the refrigerator 1 will move through the rollers 85, thereby achieving the purpose of being easy to carry.

[0036] When the height of the handle 10 needs to be adjusted, Mark loosens and removes the bolt and nut 11. Because there are multiple groups of adjustment holes on the side of the adjusting rod 9 and one group of adjustment holes on the side of the handle 10, the adjustment holes on the side of the handle 10 can be aligned with the adjustment holes on the side of the adjusting rod 9. When the adjustment holes on the side of the handle 10 correspond to the adjustment holes at the bottom of the side of the adjusting rod 9, the height of the handle 10 is the lowest at this time. When the adjustment holes on the side of the handle 10 correspond to the adjustment holes at the top of the side of the adjusting rod 9, the height of the handle 10 is the highest at this time. After the staff adjusts to the appropriate height, the bolt and nut 11 can be passed through the adjustment holes on the side of the handle 10 and the adjusting rod 9, and the bolt and nut 11 can be tightened to fix the handle 10 at the current position, thereby achieving the purpose of adjusting the height of the handle 10.

[0037] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
