For ordinary technicians in this field, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances. The following is an explanation of its embodiments based on the overall structure of the present utility model.

[0023] A DC refrigeration and freezing unit device comprises: a freezing unit 1, a hollow bin 2 is fixed at the bottom of the freezing unit 1, a support column 3 is fixed inside the hollow bin 2, a cylinder 4 is fixed on the top of the support column 3, a first support plate 5 is fixed inside the hollow bin 2, a first movable gear rod 6 is arranged inside the first support plate 5, an output end of the cylinder 4 is fixedly connected to one end of the first gear rod 6, and the output end of the cylinder 4 retracts to drive the first gear rod 6 to retreat.

[0024] Furthermore, a second support plate 7 is fixed inside the hollow bin 2, and a rotating shaft 8 is rotatably connected inside the second support plate 7. First gears 9 are fixed at both ends of the rotating shaft 8, and a second gear 10 is arranged in the middle of the rotating shaft 8. The first gear rod 6 is meshed with the second gear 10.

[0025] Next, a hollow column 11 is fixed inside the hollow bin 2, a second gear rod 12 is slidably connected inside the hollow column 11, a universal wheel 13 is provided at the bottom of the second gear rod 12, an arc-shaped opening 14 is provided on the hollow column 11, and the first gear 9 is meshed with the second gear rod 12 at the position of the arc-shaped opening 14.

[0026] At this time, when the first gear rod 6 retreats, it will drive the shaft 8 to rotate through the second gear 10, and the rotation of the shaft 8 will drive the first gear 9 to rotate. When the first gear 9 rotates, it will drive the second gear rod 12 to descend at the position of the arc-shaped opening 14. The descent of the second gear rod 12 causes the universal wheel 13 to move from the inside of the hollow column 11, and then the universal wheel 13 descends to the bottom of the hollow bin 2 through the through slot 22, which is conducive to the movement of the refrigeration unit 1.

[0027] Furthermore, one end of the first gear rod 6 can extend out of the hollow chamber 2, and a first inclined block 15 is fixed to one end of the first gear rod 6. When the first gear rod 6 moves, the first inclined block 15 is driven to move.

[0028] It should be explained that a vertical slot 16 is provided on the side wall of the hollow bin 2, and a connecting rod 17 is slidably connected to the inside of the vertical slot 16 in the vertical direction, a spring 18 is fixed to the bottom of the vertical slot 16, and the top of the spring 18 is fixedly connected to the bottom of the connecting rod 17, a vertical shaft 19 is fixed to one end of the connecting rod 17, a second inclined block 20 cooperating with the first inclined block 15 is fixed to the top of the vertical shaft 19, a suction cup 21 is fixed to the bottom of the vertical shaft 19, a through slot 22 is passed through the bottom of the hollow bin 2, the through slot 22 and the universal wheel 13 are located on the same straight line, and the inner diameter of the through slot 22 is larger than the diameter of the universal wheel 13, when the refrigeration unit 1 needs to move, the output end of the cylinder 4 retracts to drive the first gear rod 6 to retreat, and the retreat of the first gear rod 6 drives the first inclined block 15 to retreat, and then the pressure of the first inclined block 15 on the second inclined block 20 disappears, and at this time the spring 18 resets to drive the connecting rod 17 to rise and then drives the suction cup 21 to rise for the next movement.

[0029] Working principle: in the initial state, the second inclined block 20 is pressed by the first inclined block 15, the connecting rod 17 compresses the spring 18, and the suction cup 21 is adsorbed on the ground to achieve stability when the refrigeration unit 1 is placed. When the refrigeration unit 1 needs to move, the output end of the cylinder 4 retracts to drive the first gear rod 6 to retreat, and the retreat of the first gear rod 6 drives the first inclined block 15 to retreat, and then the pressure of the first inclined block 15 on the second inclined block 20 disappears. At this time, the spring 18 resets to drive the connecting rod 17 to rise and then drives the suction cup 21 to rise for the next movement. At the same time, when the first gear rod 6 retreats, it will drive the shaft 8 to rotate through the second gear 10, and the rotation of the shaft 8 drives The first gear 9 is driven to rotate. When the first gear 9 rotates, it will drive the second gear rod 12 to descend at the position of the arc-shaped mouth 14. The descent of the second gear rod 12 causes the universal wheel 13 to move from the inside of the hollow column 11, and then the universal wheel 13 descends to the bottom of the hollow bin 2 through the through groove 22, which is conducive to the movement of the refrigeration unit 1. After moving to the specified position, the output end of the cylinder 4 extends out to drive the universal wheel 13 back to the inside of the hollow column 11. Because if the universal wheel 13 is directly set at the bottom of the refrigeration unit 1, it may cause the refrigeration unit 1 to shift, so the refrigeration unit 1 automatically extends when moving and automatically retracts after reaching the destination.

[0030] The above are only preferred specific implementation methods of the utility model, but the protection scope of the utility model is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the utility model, who makes equivalent replacements or changes based on the technical scheme and utility model concept of the utility model, should be covered by the protection scope of the utility model.
