[0046] like Figure 2 and Fig.10 As shown, the display stand body 1 is provided with a moving assembly for moving equipment, and the moving assembly includes three universal wheels 51 rotatably connected to the bottom of the display stand body 1, and three electric telescopic rods 52 are fixedly connected inside the display stand body 1, and the telescopic shafts of the electric telescopic rods 52 extend to the bottom of the display stand body 1, and the bottom of the output shaft of the electric telescopic rod 52 is hinged with a support plate 53, and the bottom of the support plate 53 is set to be made of rubber material.

[0047] It should be noted that the support plate 53 and the electric telescopic rod 52 are specifically connected by a universal joint, and can be rotated at any angle, and can support the display stand body 1 in accordance with the shape of different ground or table tops;

[0048] The control method of the motor 2 42 can be to install a Bluetooth module, a wireless module or a voice control module in the circuit of the motor 2 42 in the prior art to control the driving of the click 2 42, which is not limited here.

[0049] In combination with the above preferred embodiments, the following is the entire working process and working principle of the above embodiments:

[0050] The initial state is:

[0051] The movable shell 34 is at the end of the threaded rod 1 33 closest to the motor 1 32. At this time, the lifting frame 35 is at the lowest position inside the movable shell 34. The lifting frame 35 drives the sliding rod 310 to the bottom of the inclined groove at one end of the guide groove 311 close to the motor 1 32 through the connecting rod 37. The spring 39 is not compressed. The triangular plate 43 is at the lowest position of the threaded rod 2 42. The lifting rod 44 connected to the triangular plate 43 and the support 45 are also at the lowest position. At this time, the upper surface of the support 45 The counterweight 415 is flush with the bottom of the inner side of the storage box 22. At this time, the counterweight 415 is in contact with the top of the threaded rod 42. The counterweight 415 makes the slider 48 on the side of the slide groove 47 away from the magnetic generator 46 through the pull rod 414. The counterweight 415 makes the movable tube 416 contact with the bottom of the magnetic generator 46. The pushing plate 49 is not tilted, and the torsion spring 410 is not tightened. The pushing plate 411 is not pushed, and the torsion spring 412 is not tightened. For ease of understanding, please refer to Figure 2 The internal structure of this cross-section diagram is the initial state.

[0052] Storage components hold multiple display items:

[0053] The staff places the items to be displayed on the inclined surface of the placement table 24, and under the action of the inclined surface of the placement table 24, the display items slide downward and collide with the limit block on it, and then pull the storage box 22 out of the storage slot 21 by holding the handle. Then the staff places the magnetic levitation table 23 in the storage box 22, and finally inserts the storage box 22 into the storage slot 21. After each magnetic levitation table 23 with display items is placed on the storage box 22 and all are inserted into the storage slot 21, the storage of multiple display items is realized, which can provide certain physical protection for the items to be displayed, and can also prevent unauthorized personnel from contacting and taking away the display items, prevent the display items from being accidentally lost, and can also facilitate the staff to take inventory. The internal environment of the storage box 22 is relatively stable, which can prevent the display items from being exposed to the air for a long time and being affected by factors such as dust and moisture.

[0054] The mobile assembly facilitates the movement and support of the display stand body 1:

[0055] The staff can push the display stand body 1, and the display stand body 1 can be easily moved by rolling the universal wheels 51 on the ground. When the display stand body 1 is pushed to the specified position, the staff can control the electric telescopic rod 52 to start through the controller. After the telescopic shaft of the electric telescopic rod 52 is extended, the support plate 53 moves downward synchronously. When the support plate 53 moves downward and hits the ground, the display stand body 1 is supported by the electric telescopic rod 52 to avoid displacement after the display stand body 1 is moved to the specified position. The rubber material used at the bottom of the support plate 53 is used as a footrest to play an anti-slip role. In addition, the staff can also lift it to a desktop or other platform, and support the display stand body 1 through the support plate 53 and the electric telescopic rod 52. At the same time, the continuous extension of the telescopic shaft of the electric telescopic rod 52 can also play a role in lifting the display stand body 1, thereby increasing the display height and improving the display effect.

[0056] The feeding assembly moves the corresponding display items to the tray 45:

[0057] When it is necessary to display an item, the electric control button 312 on the corresponding display item is pressed. The electric control button 312 electrically controls the motor 1 32, so that the motor 1 32 drives the threaded rod 1 33 to rotate. During the rotation of the threaded rod 1 33, the movable shell 34 moves in the lifting cavity 31 toward the middle of the display stand body 1, and the movable shell 34 drives the lifting frame 35 to move synchronously in the horizontal direction. At this time, the sliding rod 310 connected to the side of the lifting frame 35 by the connecting rod 37 and the fixed pipe 38 will move along the guide groove 311, and under the action of the spring 39 inside the fixed pipe 38, the sliding rod 310 will enter the deeper inclined groove in the guide groove 311 and move obliquely upward along the oblique groove of the guide groove 311. The oblique upward movement of the sliding rod 310 will cause the fixed pipe 38 to drive the lifting frame 35 to move upward in the movable shell 34 through the connecting rod 37. Due to the structural design of the movable shell 34, the vertical movement of the lifting frame 35 will not conflict with the horizontal movement performed by the movable shell 34. After the lifting frame 35 moves upward, it will drive the magnet 36 to move upward. At this time, the magnet 36 will pass through the bar groove and the slot 221 to move toward the placed magnetic suspension platform 23, and attract the bottom of the magnetic suspension platform 23. The magnetic suspension platform 23 can be temporarily fixed by the magnetic attraction between the magnet 36 and the magnetic suspension platform 23, so as to prevent the display items from falling off the placement platform 24 due to the skewness of the magnetic suspension platform 23 during the movement, thereby ensuring the stability of the mobile display items and ensuring that the display items can be effectively moved to the support platform 45.

[0058] During the movement of the magnetic levitation platform 23, the magnetic levitation platform 23 will contact the pushing plate 2 411, and the magnetic levitation platform 23 will push the pushing plate 2 411, so that the pushing plate 2 411 rotates to the side away from the limiting plate 413 with the connection with the pushing plate 1 49 as the axis, so that the torsion spring 2 412 is elastically tightened. At this time, the pushing plate 2 411 will not affect the movement of the display items on the placement table 24 driven by the magnetic levitation platform 23. When the magnetic levitation platform 23 passes through the pushing plate 2 411, the magnetic levitation platform 23 no longer conflicts with the pushing plate 2 411. At this time, under the elastic resetting action of the torsion spring 2 412, the pushing plate 2 411 rotates to the side close to the limiting plate 413 and conflicts with the limiting plate 413.

[0059] After the slide bar 310 slides from the horizontal groove at the top of the inclined groove of the guide groove 311, it continues to move and reaches the top of another inclined groove in the guide groove 311. At this time, the magnet 36 has moved the magnetic levitation platform 23 to the top of the support platform 45. The slide bar 310 that continues to move will move obliquely downward under the guidance of the other inclined groove of the guide groove 311. The slide bar 310 drives the lifting frame 35 to move downward inside the movable shell 34 through the fixed tube 38. The downward movement of the lifting frame 35 will drive the magnet 36 to move downward synchronously, and then the magnet 36 passes through the moving groove of the support platform 45 and moves to the bottom of the support platform 45. At this time, the magnetic levitation platform 23 is in contact with the upper surface of the support platform 45, and thus cannot move downward synchronously with the magnet 36, so that the magnetic levitation platform 23 and the magnet 36 are disconnected from the magnetic attraction relationship.

[0060] By moving the items to be displayed onto the support 45 as described above, the effect of automatic movement is achieved, thereby reducing the time required for manual selection from the storage area, and the items to be displayed are moved inside the display stand body 1, avoiding the risk of damage to the displayed items due to dropping when manually picking them up.

[0061] Center the displayed items when the positioning component is raised or lowered:

[0062] At this time, the staff can start the motor 2 41 through the controller, the motor 2 41 drives the threaded rod 2 42 to rotate, the threaded rod 2 42 drives the triangular plate 43 to move upward, and the triangular plate 43 drives the support 45 to move vertically upward inside the display stand body 1 through the lifting rod 44. During the upward movement of the support 45, the counterweight 415 will remain in place due to its own gravity, and the pull rod 414 connected to the counterweight 415 will pull the slider 48 to move inside the slide slot 47 to the side close to the magnetic generator 46, that is, to the support 45 moves in the middle, and in the process of the slider 48 moving toward the middle, it will drive the pushing plate 1 49 to move toward the middle of the support platform 45 synchronously, and the movement of the pushing plate 1 49 will drive the pushing plate 2 411 to move toward the middle synchronously. In the process of the pushing plate 2 411 moving toward the middle of the support platform 45, the pushing plate 2 411 hits the magnetic levitation platform 23. Due to the limitation of the limiting plate 413, the pushing plate 2 411 will not rotate toward the side close to the limiting plate 413, so that the pushing plate 2 411 will push the magnetic levitation platform 23 to move toward the middle of the support platform 45.

[0063] In the above process, the limit rod 417 is fixedly connected to the bottom of the magnetic generator 46, and the movable tube 416 is fixedly connected to the counterweight 415, and the two can slide relative to each other. Therefore, due to the upward movement of the support 45, the support 45 drives the limit rod 417 to move upward synchronously inside the movable tube 416 through the magnetic generator 46. When the bottom end of the limit rod 417 moves to the top of the movable tube 416, the slider 48 has been pulled by the pull rod 414 to the side of the slide groove 47 closest to the magnetic generator 46. If the support 45 continues to move upward at this time, the limit rod 417 will cooperate with the movable tube 416 to pull the counterweight 415 to move upward synchronously, thereby ensuring that the pushing plate 1 49 and the pushing plate 2 411 push the magnetic levitation platform 23 to move to the middle to reach the farthest distance, and will remain fixed thereafter.

[0064] The magnetic levitation platform 23 is pushed toward the middle by the pushing plate 1 49 and the pushing plate 2 411, so that the display items on the placement table 24 can be centered, which can ensure that the magnetic generator 46 can effectively suspend the magnetic levitation platform 23 after magnetic repulsion, and can also ensure that the display items remain in the middle after the support platform 45 rises to the highest position, avoiding misalignment of the display items and affecting the display effect.

[0065] After the support platform 45 moves upward, the support platform 45 drives the slider 48 to move upward through the slide groove 47. At this time, the bending part of the top of the pushing plate 1 49 will conflict with the bottom of the top cover 418. After the pushing plate 1 49 conflicts with the top cover 418, it will tilt and rotate outward with the connection between the pushing plate 1 49 and the slider 48 as the axis, and the pushing plate 1 49 will drive the pushing plate 2 411 to tilt and rotate outward synchronously, so that the slider 48 and the pushing plates 1 49 and 411 are hidden at the bottom of the top cover 418, avoiding the pushing plates 2 411 and 49 from blocking the display of the display items, thereby ensuring that the display items can be effectively displayed outward.

[0066] At this time, the magnetic generator 46 is restarted. After being started, the magnetic generator 46 will generate magnetic poles that are the same as the magnetic poles at the bottom of the magnetic levitation platform 23. The magnetic generator 46 exerts a repulsive force on the magnetic levitation platform 23 to achieve a levitation effect on the magnetic levitation platform 23, thereby making the display items on the placement table 24 suspend for display, thereby improving the effect of the display items.

[0067] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
