DETAILED DESCRIPTION

[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0021] Reference Figure 1-Figure 5 Figure 1-Figure 5 , a multi-angle display stand for exhibition halls, includes a base 1 provided with moving wheels, and a support 4 and a display board 17 are provided on the base 1. A bearing (not shown in the attached drawings of the specification) is fixedly installed inside the base 1, and the base 1 is rotatably connected to a rotating shaft 2 through the bearing. The support 4 is provided on the rotating shaft 2. The rotating shaft 2 is vertically arranged, and a gear 3 is fixedly installed on the rotating shaft 2. A sleeve 5 is rotatably installed on the base 1, and an annular rack 6 engaged with the gear 3 is integrally connected inside the sleeve 5. A handle is fixedly installed on the sleeve 5;

[0022] By pulling the handle, the rotating shaft 2 can drive the support 4 and the display board 17 to rotate, so as to adjust the display orientation of the display items;

[0023] An upper card slot and a lower card slot are respectively opened on the support 4. The support 4 is of a U-shaped structure, and the upper card slot and the lower card slot are horizontally opened from top to bottom. A first motor 7 is fixedly installed in the upper card slot, and the output end of the first motor 7 is fixedly connected to a first lead screw 9. A first nut 11 that matches is slidably sleeved on the first lead screw 9;

[0024] It should be noted that the initial state of the connecting rod 14 and the display board 17 is a vertical state;

[0025] A second motor 8 is fixedly installed in the lower card slot, and the output end of the second motor 8 is fixedly connected to a second lead screw 10. A second nut 12 that matches is slidably sleeved on the second lead screw 10;

[0026] Two guide grooves 18 communicating with the upper card slot and the lower card slot are opened on the support 4, and guide blocks 19 extending into the guide grooves 18 are fixedly installed on the first nut 11 and the second nut 12. The mutual cooperation of the guide grooves 18 and the guide blocks 19 can limit the moving directions of the first nut 11 and the second nut 12;

[0027] A bracket 13 is movably installed on the first nut 11, and a connecting rod 14 connected to the second nut 12 is slidably sleeved inside the bracket 13. The first lead screw 9 and the second lead screw 10 are horizontally arranged, and one end of the bracket 13 away from the connecting rod 14 is pin-connected to the first nut 11;

[0028] A guide plate 15 cooperating with the bracket 13 is fixedly installed on the connecting rod 14. The display board 17 is arranged on the connecting rod 14. A guide long hole 16 for guiding the guide plate 15 is opened on the bracket 13, and one end of the connecting rod 14 away from the guide plate 15 is pin-connected to the second nut 12. The guide long hole 16 plays a role in guiding the guide plate 15;

[0029] When the first nut 11 is driven by the first motor 7 to slide to the left, it drives the bracket 13 to move. When the bracket 13 moves, it pulls the connecting rod 14 to deflect with the pin point as the fulcrum, so that the angle between the connecting rod 14 and the display board 17 is in a top view state;

[0030] When the nut 12 slides to the left side through the drive of the motor 8, the traction connecting rod 14 is deflected, so that the upper end of the connecting rod 14 slides in the bracket 13, so that the angle between the connecting rod 14 and the display board 17 is in an upward state;

[0031] By adjusting the display angles of the connecting rod 14 and the display board 17, the display board 17 can display the exhibits from different angles, so that people around can view the exhibits from the best angle;

[0032] It should be noted that the specific models and specifications of motor 1 7 and motor 2 8 need to be selected and determined according to the actual specifications of the device, and the specific selection calculation method adopts the existing technology in this field, so it is not repeated here.

[0033] The functional principle of the utility model can be explained through the following operation modes:

[0034] The base 1 is moved to a designated position by the moving wheels, and the displayed items are fixed by the display board 17;

[0035] When the angle of the display board 17 needs to be adjusted;

[0036] When the angle of the exhibit needs to be adjusted to be viewed from above;

[0037] The output end of the second motor 8 drives the second screw rod 10 to rotate. The second screw rod 10 drives the second nut 12 to slide to the left when rotating. The second nut 12 is guided by the guide block 19 and the guide groove 18. When the second nut 12 moves, it pulls the connecting rod 14 to deflect, so that the connecting rod 14 drives the display board 17 to deflect synchronously when deflecting.

[0038] At the same time, the position difference generated by the deflection of the connecting rod 14 pulls the guide plate 15, so that when the guide plate 15 slides in the guide slot 16, the pulling bracket 13 deflects with the pin point as the fulcrum, thereby adjusting the display board 17 and the display item to be viewed from above;

[0039] When the angle of the exhibit needs to be adjusted to a top-down view;

[0040] The output end of the motor 7 drives the screw rod 9 to rotate, and the screw rod 9 drives the nut 11 to slide to the left when rotating. The nut 11 is guided by the guide block 19 and the guide groove 18. When the nut 11 moves, it drives the bracket 13 to move synchronously. When the bracket 13 moves, the connecting rod 14 and the guide plate 15 slide in the bracket 13 and the guide long hole 16. When the bracket 13 drives the upper end of the connecting rod 14 to slide to the left, the connecting rod 14 deflects with the nut 2 12 as the fulcrum, so that the connecting rod 14 drives the display board 17 to present a top-down angle;

[0041] When the orientation of the display board 17 needs to be adjusted;

[0042] The traction handle is rotated, so that the handle drives the sleeve 5 and the annular rack 6 to move. When the annular rack 6 rotates, it drives the meshing gear 3 to rotate, so that the gear 3 drives the rotating shaft 2 to rotate on the base 1. When the rotating shaft 2 rotates, it can drive the support 4 and the display board 17 to rotate, so that the exhibits can be displayed in multiple directions.

[0043] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
