[0002] Display cabinets are a type of props, mainly used in shopping malls, supermarkets, museums and other places to display and collect exhibits. In exhibition activities, display cabinets are an important tool for displaying products and attracting audiences.

[0003] However, most of the existing display cabinets are fixed in design and difficult to move, which cannot meet the needs of frequent replacement of booths in exhibitions. In addition, when exhibits are displayed, since the exhibits are directly placed on the partition board, the exhibits may fall due to the centrifugal force during the rotation of the partition board, and may also fall due to accidental touch, resulting in damage to the exhibits. Therefore, a mobile display cabinet applied to exhibition booths is proposed to solve the above problems.

[0004] The above information disclosed in the background technology is only used to increase the understanding of the background technology of the present application, and therefore, it may include information that does not constitute the prior art known to ordinary technicians in the field.

The bottom end of the lifting frame 103 passes through the mobile base 1, and a lifting plate 104 is welded to the outer wall of the bottom middle section of the lifting frame 103. The middle inner walls of the upper and lower sides of the mobile base 1 are rotatably connected with threaded rods 105, and the lifting plate 104 is threadedly connected to the outer wall of the threaded rod 105. A reducer 106 is fixedly installed on the top inner wall of the mobile base 1. A servo motor 107 is also fixedly installed on the top inner wall of the mobile base 1. The output shaft of the servo motor 107 is connected to the input end of the reducer 106, and the output end of the reducer 106 is fixedly connected to the top of the threaded rod 105.

[0023] The inner wall of the display rack 2 is fixedly connected with a plurality of display boards 3, the outer walls of the plurality of display boards 3 are rotatably connected with a rotating gear disc 6, the middle top outer wall of the rotating gear disc 6 is fixedly connected with a placement rack 7 for placing exhibits, and the outer wall of the rotating gear disc 6 is installed with a fixed exhibit clamping mechanism.

[0024] The clamping mechanism includes a U-shaped fixing frame 601 fixedly connected to the outer wall of the middle section of the top of the rotating gear disk 6, the inner wall of the U-shaped fixing frame 601 is rotatably connected to a bidirectional screw rod 602, the outer wall of the bidirectional screw rod 602 is symmetrically threadedly connected to two clamping plates 603, and the top ends of the two clamping plates 603 are both located above the placement rack 7.

[0025] The clamping mechanism also includes two limit rods 604 fixedly connected to the inner wall of the U-shaped fixing frame 601, the bidirectional screw rod 602 is located between the two limit rods 604, and the two limit rods 604 pass through the two clamping plates 603, and one end of the bidirectional screw rod 602 passes through the U-shaped fixing frame 601 and is fixedly connected to a knob 605.

[0026] The inner walls of the upper and lower sides of the display rack 2 are rotatably connected with a rotating shaft 301, which passes through multiple display boards 3. The outer wall of the rotating shaft 301 is fixedly connected with multiple gears 302, which are located above the display boards 3, and the multiple gears 302 are meshed with multiple rotating gear plates 6.

[0027] A driving motor 303 is fixedly mounted on the top outer wall of the display rack 2 , and the output shaft end of the driving motor 303 passes through the top of the display rack 2 and is fixedly connected to the top of the rotating shaft 301 .

[0028] The implementation principle of a mobile display cabinet used in an exhibition booth of the present application is as follows: when in use, the exhibits are placed on a plurality of placement racks 7, and then the knob 605 is turned through the clamping mechanism, and the knob 605 drives the bidirectional screw rod 602 to rotate, so that the bidirectional screw rod 602 is threadedly rotated on the inner surface of the bottom end of the two clamping plates 603. Since the threads of the bidirectional screw rod 602 and the two clamping plates 603 are symmetrically arranged in opposite directions, the two clamping plates 603 are relatively moved, and the two clamping plates 603 are relatively moved and gradually approach the exhibits until the exhibits are clamped and fixed;

[0029] It is worth noting that when the two clamping plates 603 move relative to or away from each other, they will slide on the outer walls of the two limiting rods 604. The limiting rods 604 limit the clamping plates 603. On the one hand, they can increase the stability of the movement of the clamping plates 603, and on the other hand, they can prevent the clamping plates 603 from rotating due to the rotation of the bidirectional screw rod 602.

[0030] Then, the mobile base 1 needs to be moved to a suitable position, and the servo motor 107 is started through the lifting mechanism. The output shaft of the servo motor 107 inputs power into the reducer 106, and the output end of the reducer 106 drives the threaded rod 105 to rotate, thereby causing the threaded rod 105 to rotate on the inner surface of the middle of the lifting plate 104. At this time, the threaded rod 105 drives the lifting plate 104 to slide up and down. When the lifting plate 104 slides upward, it will drive the lifting frame 103 to rise, and the lifting frame 103 will drive the multiple support columns 5 to retract into the mobile base 1, so that the multiple universal wheels 4 are in contact with the ground. At this time, the mobile base 1 can be pushed to make the multiple universal wheels 4 roll on the ground, which is convenient for the movement of the mobile base 1;

[0031] It is worth noting that when the lifting frame 103 is lifted up and down, it will drive multiple sliders 102 to slide on the outer wall of the guide rail 101, which plays a limiting role, so that the lifting frame 103 always moves linearly when sliding up and down, and will not tilt, which effectively increases the lifting stability;

[0032] When the mobile base 1 moves to a suitable position, the servo motor 107 drives the threaded rod 105 to rotate in the opposite direction through the reducer 106. Similarly, the threaded rod 105 drives the lifting plate 104 to descend. At this time, the lifting plate 104 drives the lifting frame 103 to descend, and the lifting frame 103 drives the multiple support columns 5 to extend out of the mobile base 1 until the multiple universal wheels 4 are lifted up to support the mobile base 1 instead of the universal wheels 4, so that the mobile base 1 can be fixed;

[0033] During display, the drive motor 303 is started, and the output shaft of the drive motor 303 drives the rotating shaft 301 to rotate, and the rotating shaft 301 drives the multiple gears 302 to rotate, and the multiple gears 302 drive the rotating toothed disk 6 meshing therewith to rotate, so that the rotating toothed disk 6 can drive the exhibit to rotate, which is convenient for displaying the exhibit at multiple angles.
