Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0033] Reference Figure 1 - Figure 3 The present invention provides an embodiment of a movable display cabinet, comprising a display cabinet body 1, a movable mechanism provided inside the display cabinet body 1, the movable mechanism including a lifting component 2 and a protective component 3, the lifting component 2 including a support plate 21, the support plate 21 being slidably connected to the inner wall of the display cabinet body 1, and a universal wheel 22 being fixedly installed on the lower surface of the support plate 21, the universal wheel 22 being able to contact or detach from the ground by sliding the support plate 21, so as to move or fix the display cabinet body 1.

[0034] Reference Figure 3 - Figure 4 A crankshaft 23 is rotatably connected to the inner wall of the display case body 1. A connecting rod 24 is hinged to the outer wall of the crankshaft 23. The end of the connecting rod 24 away from the crankshaft 23 is hinged to the upper surface of the support plate 21. The rotation of the crankshaft 23, in conjunction with the connecting rod 24, can drive the support plate 21 to slide on the inner wall of the display case body 1. The sliding of the support plate 21 can drive the caster wheel 22 to move up and down. A worm gear 25 is fixedly installed on the outer wall of the crankshaft 23. A motor 26 is fixedly installed on the inner wall of the display case body 1. A worm 27 is fixedly installed on the output end of the motor 26. The worm 27 meshes with the worm gear 25. When the motor 26 drives the worm 27 to rotate, it can drive the crankshaft 23 to rotate on the inner wall of the display case body 1 in conjunction with the worm gear 25.

[0035] Reference Figure 5 - Figure 6 The protective component 3 includes a baffle 31, which is hinged to the outer wall of the display case body 1. When the baffle 31 is rotated to a horizontal position, it will not affect the display effect of the items inside the display case body 1. When the baffle 31 is rotated to a vertical position, it can protect the items inside the display case body 1 and prevent them from sliding off. A limit groove 32 is provided on the right side of the baffle 31. A sliding frame 34 is slidably connected to the outer wall of the display case body 1. A through groove 35 is provided on the sliding frame 34. A column 36 is fixedly installed on the top of the sliding frame 34. While the sliding frame 34 slides on the outer wall of the display case body 1, it can drive the pin 38 to move synchronously with the column 36. An L-rod 37 is fixedly installed on the outer wall of the crankshaft 23. The outer wall of the L-rod 37 fits against the inner wall of the through groove 35. During the rotation of the crankshaft 23, it can drive the sliding frame 34 to slide on the outer wall of the display case body 1 in conjunction with the L-rod 37 and the through groove 35. The inner wall of the column 36 is penetrated and slides through the crankshaft 23. A pin 38 is connected, with one end of the pin 38 fitting against the inner wall of the limiting groove 32, and a limiting block 39 fixedly installed at the other end of the pin 38. When the sliding frame 34 slides on the outer wall of the display cabinet body 1, it can drive the baffle 31 to rotate on the outer wall of the display cabinet body 1 in conjunction with the column 36, the pin 38, and the limiting groove 32. A spring 310 is fixedly installed on the left side of the limiting block 39, and the end of the spring 310 away from the limiting block 39 is fixedly installed on the outer wall of the column 36, pulling the limiting block. 39 stretches the spring 310 and drives the pin 38 to slide on the inner wall of the column 36, causing the pin 38 to slide out of the limiting groove 32. When the pin 38 slides out of the limiting groove 32, it will release the limitation on the baffle 31. A torsion spring 33 is provided at the hinge between the baffle 31 and the display cabinet body 1. When the pin 38 releases the limitation on the baffle 31, the elasticity of the torsion spring 33 can drive the baffle 31 to flip upward and reset. At this time, the baffle 31 can protect the items inside the display cabinet body 1.

[0036] Working principle: When the display case body 1 needs to be moved, the starter motor 26 drives the worm gear 27 to rotate. Simultaneously, the worm gear 27 rotates, causing the meshing worm wheel 25 to rotate. The worm wheel 25 then drives the crankshaft 23 to rotate on the inner wall of the display case body 1. The crankshaft 23, in turn, pushes the connecting rod 24 downwards, causing the connecting rod 24 to push the support plate 21 downwards. The support plate 21 then slides downwards on the inner wall of the display case body 1. During this downward sliding, the support plate 21 drives the casters 22 to move downwards synchronously. When the casters 22 contact the ground, they support the display case body 1, allowing the bottom of the display case body 1 to lift off the ground. At this point, the display case body 1 can be pushed, allowing the casters 22 to remain on the ground. The display case body 1 can be moved by rolling, without having to unlock multiple sets of casters 22 one by one, making operation simpler and more convenient. Conversely, when the motor 26 drives the worm gear 27 to rotate, the worm gear 27 drives the worm wheel 25 meshing with it to rotate in reverse. The worm wheel 25 will drive the crankshaft 23 to rotate. At this time, the crankshaft 23 will pull the connecting rod 24 upward, so that the connecting rod 24 will pull the support plate 21 upward. At this time, the support plate 21 will slide upward on the inner wall of the display case body 1. During the upward sliding of the support plate 21, the casters 22 will move upward in sync. When the bottom of the display case body 1 contacts the ground during the upward movement of the casters 22, the position of the display case body 1 can be fixed.

[0037] As the crankshaft 23 rotates and pushes the connecting rod 24 downward, it drives the L-rod 37 to rotate around the worm gear 25. At this time, the L-rod 37 moves against the inner wall of the through groove 35, and simultaneously pushes the sliding frame 34 upward, causing it to slide upward on the outer wall of the display cabinet body 1. As the sliding frame 34 slides upward, it drives the upright 36 to move upward simultaneously. Simultaneously, the upright 36 moves upward, driving the pin 38 to move upward. At the same time, as the pin 38 moves upward, it moves against the inner wall of the limiting groove 32 and pushes the baffle 31 upward, causing the baffle 31 to move upward within the display cabinet body 1. When the outer wall of the display cabinet flips upward, the baffle 31 forms a partition around the display cabinet body 1 to prevent items from sliding off the display cabinet body 1 during movement, thus protecting the items displayed on the display cabinet body 1 and preventing property damage. Conversely, when the crankshaft 23 rotates and pulls the connecting rod 24 upward, it can drive the baffle 31 to flip downward on the outer wall of the display cabinet body 1 in conjunction with the L rod 37, through groove 35, sliding frame 34, column 36, pin 38 and limiting groove 32, so that the baffle 31 can be flipped to a horizontal state without affecting the display effect of the items inside the display cabinet body 1.

[0038] When the display case body 1 is placed on the ground to display items, the limit block 39 is pulled to stretch the spring 310 and drive the pin 38 to slide on the inner wall of the column 36, so that the pin 38 slides out of the limit groove 32. When the pin 38 slides out of the limit groove 32, it will release the limit on the baffle 31. At this time, under the elastic action of the torsion spring 33, the baffle 31 will be driven to flip upward and reset. At this time, the baffle 31 can protect the items inside the display case body 1 and prevent some round items from rolling off the display case body 1 during the display process.

[0039] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
