[0030] The curved side of the rotating column 220 has three sets of annular grooves from top to bottom. Each set of annular grooves consists of four sets of equally spaced slots 221. Therefore, twelve sets of display trays 230 of the same specifications can be installed on the outside of the rotating column 220. The display trays 230 have three types with the same structure but different sizes. Multiple display trays 230 can be used selectively, which greatly improves the flexibility of the expansion component 200 and reduces the space occupied by the expansion component 200.

[0031] A sliding groove 222 is vertically provided above the slot 221, a cavity is provided on the rear side of the sliding groove 222, a push button 300 is provided on the front side of the sliding groove 222, and a locking component is provided inside the cavity.

[0032] The locking assembly includes a movable base 310 for moving the locking lever 320 up and down, and a return spring 330 is fixed above the cavity.

[0033] The movable base 310 has a cylindrical structure, and the shape of the movable base 310 matches the shape of the cavity. The front of the movable base 310 is fixed to the back of the push button 300 by a connecting rod.

[0034] Each set of slots 221 has a display panel 230 installed on its outer side. The display panels 230 have several sets with the same structure but different specifications.

[0035] Example 1: Please refer to Figures 1 to 4 In actual use, the main body 100 of the publicity device is installed on the ground of the display area. The top of the main body 100 of the publicity device is equipped with a rainproof canopy 110, which can protect the main body 100 of the publicity device. A multimedia screen 120 is installed on the upper left side of the front of the main body 100 of the publicity device. The multimedia screen 120 plays publicity and display videos in a loop to achieve the publicity effect (the multimedia screen 120 is existing technology, and its internal structure and working principle will not be described in detail here). An information posting area 130 is provided on the right side of the multimedia screen 120. Paper with the text of the publicity and display information can be pasted on the information posting area 130 to carry out multi-level publicity and display in conjunction with the multimedia screen 120. A self-service opening 140 for publicity materials is welded below the information posting area 130. Participants can take publicity materials from the self-service opening 140 for viewing or carrying.

[0036] Inside the main body 100 of the promotional device, on the right side, are two sets of identical extension components 200. Each extension component 200 includes a rotating column 220 and a display tray 230. The rotating column 220 is mounted on top of a power base 210. The rotating column 220 is driven to rotate at a uniform and slow speed by a motor and shaft inside the power base 210 (the motor is existing technology, and its internal structure and working principle will not be described here). Three sets of annular grooves are sequentially formed on the curved side of the rotating column 220 from top to bottom. Each set of annular grooves consists of four slots 221. A locking rod 320 is installed inside the upper part. A display plate 230 is installed on the outside of each set of slots 221. A plug 231 is provided on the side of the display plate 230 near the center. The top of the plug 231 has a locking hole 232 that mates with the locking rod 320. Through the interlocking connection between the plug 231 and the slot 221 and the interlocking connection between the locking rod 320 and the locking hole 232, the display plate 230 can be installed on the outside of the slot 221. Since there are three sets of annular grooves, twelve sets of display plates 230 of the same specifications can be installed on the outside of the rotating column 220.

[0037] It should be noted that the display tray 230 has several sets with the same structure but different specifications. Specifically, it has three different sizes of display trays 230, the radius lengths of the three display trays 230 are in an arithmetic sequence, and the plugs 231 on the three display trays 230 are exactly the same. Therefore, theoretically, the curved side of the rotating column 220 can be equipped with three different sizes of display trays 230. At the same time, each of the three different sizes of display trays 230 has twelve sets of the same specifications. These display trays 230 are integrated and vertically installed on the outside of the rotating column 220. The rotating column 220 is driven by a motor to rotate at a uniform and slow speed. Therefore, the final effect is to greatly reduce the space occupied by the expansion component 200, while meeting the diverse display needs of the expansion component 200, and significantly improving the flexibility of the expansion component 200.

[0038] Example 2: Please refer to Figure 3 and Figure 4When the display plate 230 needs to be replaced, first locate the push button 300 in front of the sliding groove 222 above the slot 221. Pinch the push button 300 and push it upwards. This will cause the moving base 310 inside the cavity to move upwards along the cavity via the connecting rod, pressing the return spring 330 fixed above the cavity. This will cause the return spring 330 to contract and store force. At the same time, the moving base 310 will cause the locking rod 320 below it to move inwards towards the cavity, causing the bottom of the locking rod 320 to disengage from the locking hole 232. This releases the lock between the locking lever 320 and the insert 231, thereby releasing the lock on the display tray 230. After the display tray 230 is removed, the insert 231 on the back of the new display tray 230 is inserted into the slot 221. Then, the push button 300 is released to allow the return spring 330 to return, pushing the moving base 310 downward to drive the locking lever 320 downward to re-engage with the locking hole 232, thus completing the replacement of the display tray 230. Therefore, the final effect is to greatly improve the efficiency of replacing and maintaining the display tray 230.

[0039] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. 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.
