Detailed Description

The following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present utility model, but not all embodiments.

Example 1

Referring to fig. 1-4, an exhibition stand comprises an annular frame 1 and a base 2, wherein the annular frame 1 is positioned at the outer edge of the upper end of the base 2;

the inner side of the annular frame 1 is provided with a transmission structure which is connected with an external motor, the transmission structure comprises a rotating shaft 8, a worm wheel 7, a worm 11 and a connecting rod 14, the rotating shaft 8 is fixedly arranged at the center of the upper part of the base 2, the connecting rod 14 is connected between the turntable 6 and the worm wheel 7, the worm wheel 7 is rotatably arranged at the top of the rotating shaft 8, the worm wheel 7 and the worm 11 are meshed with each other, the tail end of the worm 11 is connected with an output shaft of the motor,

the bottom of the tray 3 is provided with a limiting rod 9, a positioning hole 10 is formed in the round position of the upper part of the turntable 6, the limiting rod 9 is inserted into the inner side of the positioning hole 10, the size of the limiting rod 9 is matched with that of the positioning hole 10, when the tray is installed, the limiting rod 9 at the lower end of the tray 3 is inserted into the inner side of the positioning hole 10 of the turntable 6 below to position the tray 3, the tray 3 is circularly arranged, the outer edge of the tray 3 is mutually attached to the inner wall of the annular frame 1, the annular frame 1 can also have a limiting effect on the tray 3 in the rotating process of the tray 3, and related products and product introduction which are visually conveyed are displayed to surrounding people in an omnibearing manner along with the rotation of the tray 3;

the upper part of the transmission structure is rotatably provided with a turntable 6, the upper part of the turntable 6 is provided with a plurality of groups of supporting structures, the plurality of groups of supporting structures are distributed on the upper part of the turntable 6 in an annular array, and trays 3 are placed between the upper parts of the plurality of groups of supporting structures;

the supporting structure comprises a supporting block 4, a square groove 5 and a connecting column 12, wherein the square groove 5 is penetratingly arranged on the tray 3, the connecting column 12 is arranged on the inner side of the square groove 5, the supporting block 4 is sleeved on the outer side of the connecting column 12, and the size of the supporting block 4 is matched with the size of the square groove 5.

When the user needs to carefully watch, the user can change the rotating state of the tray 3 into the static state by pressing the tray 3, so that the user can conveniently carefully watch products, and after the tray 3 is static, the lower turntable 6 can still rotate, because when the turntable 6 drives the tray 3 above to rotate, the friction force between the turntable 6 and the tray 3 is relied on, when the external force breaks the balance state maintained by the friction force, the relative rotation condition between the turntable 6 and the tray 3 occurs, and meanwhile, the tray 3 can stop rotating at any time, so that potential danger caused by the fact that the child drags limbs if the tray 3 continues to rotate after the child carelessly contacts with the tray 3 after clothes are blocked can be prevented;

with the help of being a plurality of supporting shoe 4 that fan-shaped set up with tray 3 hold in the palm the up end from carousel 6, in order to prevent that tray 3 from appearing the condition of negative pressure between annular frame 1 inboard and carousel 6, appear the negative pressure, can lead to the tray 3 to hardly follow the inside problem of taking out of annular frame 1, outside motor drive worm 11 rotate, and intermeshing's worm wheel 7 consequently obtains power, and then on the connecting rod 14 through the upper end with kinetic energy transfer to carousel 6, drive carousel 6 and rotate.

Example 2

Referring to fig. 5, the difference between the present embodiment and embodiment 1 is that the height of the upper end surface of the supporting block 4 is higher than that of the upper end surface of the turntable 6, a rubber pad 13 is bonded on the upper end surface of the supporting block 4, the upper end surface of the rubber pad 13 and the lower end surface of the tray 3 are mutually bonded, and the friction force between the supporting block 4 and the tray 3 can be increased by the rubber pad 13 due to the influence of the friction coefficient, meanwhile, the supporting block 4 and the tray 3 can be protected, and after the friction force is increased, an external force is applied to the tray 3, and still the rotation can be stopped.

The working principle of the device is as follows:
