[0029] The movable plate 10 slides on both sides of the movable groove 21, the limit card block 23 is embedded in the limit card slot 24, the caster 3 is installed at the bottom end of the bottom cabinet 1 through the mounting plate 5, the bottom cabinet 1 and the upper cabinet 8 are fixed by the limit card slot 24 and the limit card block 23, and the upper cabinet 8 is provided with two groups, and the two groups of upper cabinets 8 are fixed by the limit card slot 24 and the limit card block 23;

[0030] Specifically, Figure 1 , Figure 3 and Figure 5 As shown, the upper cabinet 8 is placed on the top of the bottom cabinet 1. After placing it, pull the movable plate 10 so that the movable plate 10 squeezes the spring 20 to move closer to the middle, and then place the movable plate 10 inside the movable groove 21. When placing the movable plate 10, align the limit block 23 with the limit groove 24. After alignment, release the movable plate 10, and the spring 20 uses its own elasticity to make the limit block 23 rebound to the inside of the limit groove 24, so that the fixed block 9 can be limited and fixed to prevent the upper cabinet 8 from shaking on the top of the bottom cabinet 1 when the overall movement occurs.

[0031] Embodiment 2: Both sides of the bottom cabinet 1 are fixedly connected with connecting blocks 6, a servo motor 7 is installed on the top of the connecting block 6, a threaded rod 11 is fixedly connected to the output end of the servo motor 7, a threaded sleeve 4 is arranged on the outside of the threaded rod 11, the bottom end of the threaded sleeve 4 is fixedly connected with a limiting plate 2, the bottom end of the limiting plate 2 is arranged with an anti-slip pad 12, the top of the threaded sleeve 4 close to the inner side is fixedly connected with a slider 19, both sides of the bottom cabinet 1 are provided with limiting slide grooves 18, the slider 19 is arranged inside the limiting slide grooves 18, the slider 19 slides up and down inside the limiting slide grooves 18, the limiting plates 2 are arranged on both sides of the bottom end of the bottom cabinet 1, and the threaded rod 11 and the threaded sleeve 4 cooperate with each other;

[0032] Specifically, Figure 1 , Figure 3 and Figure 4 As shown, after the ice cream cabinet is pushed to a suitable position, the servo motor 7 is started, and the servo motor 7 drives the threaded rod 11 to rotate. Since the threaded rod 11 and the threaded sleeve 4 cooperate with each other and the limit plate 2 is fixedly connected to the bottom end of the threaded sleeve 4, the rotation of the threaded rod 11 can make the threaded sleeve 4 drive the limit plate 2 to descend. The descent of the limit plate 2 can limit the caster 3 on the ground to prevent the caster 3 from accidentally driving the ice cream cabinet to move. The limit block 16 can further prevent the caster 3 from accidentally sliding, and the slider 19 can limit the threaded sleeve 4.

[0033] Embodiment 3: A reserved groove 13 is respectively provided on the right side of the rear end of the bottom cabinet 1 and the upper cabinet 8, and a baffle 17 is fixedly connected at the four corners inside the reserved groove 13. A ventilation and heat dissipation plate 15 is arranged inside the reserved groove 13. A movable block 14 is movably hinged on both sides of the upper and lower ends of the reserved groove 13, and a convex block 25 is fixedly connected to the side of the movable block 14 close to the middle.

[0034] Specifically, Figure 3 and Figure 6 As shown, when it is necessary to clean the ventilation and heat dissipation plate 15 or to inspect the components inside the bottom cabinet 1 and the upper cabinet 8, the movable block 14 is rotated to make the protrusion 25 disengage from the inside of the groove 26, so that the ventilation and heat dissipation plate 15 can be unfixed. If the ventilation and heat dissipation plate 15 is unfixed, the ventilation and heat dissipation plate 15 can be disassembled. Disassembling the ventilation and heat dissipation plate 15 can not only clean the ventilation holes inside the ventilation and heat dissipation plate 15, but also facilitate the inspection of the components inside the bottom cabinet 1 and the upper cabinet 8. When it needs to be installed, the ventilation and heat dissipation plate 15 is placed inside the reserved groove 13 again, and then the movable block 14 is flipped over so that the protrusion 25 is embedded in the inside of the groove 26.

[0035] Working principle: When the present invention is in use, the upper cabinet 8 is placed on the top of the bottom cabinet 1. After placing it, the movable plate 10 is pulled to make the movable plate 10 squeeze the spring 20 to move closer to the middle, and then the movable plate 10 is placed inside the movable groove 21. When placing the movable plate 10, the limiting card block 23 is aligned with the limiting card groove 24. After alignment, the movable plate 10 is released, and the spring 20 uses its own elasticity to make the limiting card block 23 rebound to the inside of the limiting card groove 24, so that the fixed block 9 can be limited and fixed to prevent the upper cabinet 8 from shaking at the top of the bottom cabinet 1 when the whole is moved. After fixing, the ice cream cabinet is pushed to move to a suitable position. After moving to a suitable position, the servo motor 7 is started, and the servo motor 7 drives the threaded rod 1 1 is rotated, and the rotation of the threaded rod 11 can make the threaded sleeve 4 drive the limit plate 2 to descend.

The limit block 16 can further prevent the caster 3 from accidentally sliding. When it is necessary to clean the ventilation and heat dissipation plate 15 or to inspect the components inside the bottom cabinet 1 and the upper cabinet 8, the movable block 14 is rotated to make the protrusion 25 disengage from the inside of the groove 26, so that the ventilation and heat dissipation plate 15 loses its fixation. If the ventilation and heat dissipation plate 15 loses its fixation, the ventilation and heat dissipation plate 15 can be disassembled. Disassembling the ventilation and heat dissipation plate 15 can not only clean the ventilation holes inside the ventilation and heat dissipation plate 15, but also facilitate the inspection of the components inside the bottom cabinet 1 and the upper cabinet 8.
