Description

Technical Field

[0001] This utility model relates to the field of advertising machine technology, and in particular to an advertising machine with a rotating structure. Background Technology

[0002] An advertising display machine is a new generation of intelligent device that forms a complete advertising broadcasting and control system through terminal software control, network information transmission, and multimedia terminal display. It can conduct advertising through multimedia materials such as images, text, videos, and widgets (e.g., weather, exchange rates).

[0003] The rotating advertising machine is installed vertically, but a rotating disc is added to the display screen, allowing the screen to be displayed vertically or horizontally, and rotated at multiple angles, making marketing displays more flexible. Since the screen of the rotating advertising machine can be displayed horizontally or vertically, it can be more flexible and perfectly adapted to the display of multimedia content such as videos, pictures, and text, improving the effectiveness of advertising and marketing, and providing a good interactive experience.

[0004] In the process of advertising, users usually need to manually adjust the screen orientation to switch between landscape and portrait display modes. However, in actual operation, when users rotate excessively or adjust unevenly, the screen is prone to unexpected tilting and shifting, resulting in misalignment of the displayed image. Insufficient precision of manual adjustment will directly affect visual continuity. Utility Model Content

[0005] Therefore, it is necessary to provide an advertising machine with a rotating structure to address the problem that, in actual operation, when users rotate the screen excessively or adjust it unevenly, the screen is prone to unexpected tilting and shifting, resulting in misalignment of the displayed image and distortion of text and images. Insufficient precision in manual adjustment will directly affect visual continuity.

[0006] An advertising machine with a rotating structure includes: a support frame, an advertising machine body movably mounted above the support frame, a rotating shaft fixedly connected to the center of one outer wall of the advertising machine body, and one end of the rotating shaft inserted into the interior of the support frame to drive the advertising machine body to rotate.

[0007] The first magnet is located inside the bracket and rotates around the pivot. A plurality of second magnets are arranged in a ring at equal intervals on one side of the pivot. The first magnet is magnetically attracted to the plurality of second magnets to limit the position of the advertising machine body.

[0008] In one embodiment, a bearing ring is fixedly fitted onto the surface of the rotating shaft, and the outer wall of the bearing ring is fixed onto the inner wall of the bracket.

[0009] In one embodiment, a rotating gear is fixedly connected to one end of the rotating shaft, and a damping gear is meshed with one side of the rotating gear. The axis of the damping gear is fixed to the inner wall of the bracket by a fixed shaft.

[0010] In one embodiment, a fixed column is fixedly connected to one end of the rotating gear away from the rotating shaft, a support frame is fixedly connected to one side of the fixed column, and one side of the first magnet is fixed to the support frame.

[0011] In one embodiment, a fixing ring is fixedly connected to the inner wall of one side of the bracket, and a limiting ring is fixedly connected to the outer wall of the fixing ring near the bracket. The limiting ring is sleeved on the surface of a plurality of second magnets with the rotating shaft as the axis.

[0012] In one embodiment, both the rotating gear and the fixed column are located inside the bracket and rotate coaxially with the rotating shaft.

[0013] In one embodiment, a cover plate is fixedly connected to the end of the fixed column away from the rotating gear, and the cover plate is at the same horizontal height as the outer wall of the bracket and the fixed ring.

[0014] In one embodiment, a pin is fixedly connected to one side of the outer wall of the cover plate, and a plurality of limiting blocks are fixedly connected to one side of the outer wall of the fixing ring at equal intervals, the spacing between the plurality of limiting blocks being the same as the spacing between the plurality of second magnets.

[0015] Beneficial effects

[0016] 1. When the user rotates the advertising machine, the first magnet and different second magnets generate magnetic attraction, forming positioning points distributed at equal angles. The magnetic attraction structure achieves stepless adjustment through the magnetic damping effect of the first and second magnets. The user can switch between horizontal and vertical screen modes by simply pushing the advertising machine. The magnetic attraction automatically corrects the offset, avoiding the wear problem of traditional mechanical buckles. It can flexibly adapt to different usage environments, taking into account both smooth rotation and reliable positioning, and significantly improving the advertising display effect.

[0017] 2. The rigid connection between the fixed column and the rotating gear ensures that the first magnet rotates synchronously with the shaft, maintaining the magnetic alignment accuracy with the second magnet. The inner wall of the limiting ring is made of a low-friction coefficient material, which allows the second magnet to rotate smoothly and prevents the magnet assembly from shifting axially due to centrifugal force through the ring-shaped wrapping structure. The dual constraint of the support frame and the limiting ring ensures that the magnetic attraction structure maintains its positioning stability under rotation or external impact. In addition, the fixed ring, as a reinforcing structure of the support, can disperse the stress when the shaft rotates and extend the service life of the overall mechanism.

Detailed Implementation

[0026] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0027] The following is combined Figures 1-5 This invention describes an advertising machine with a rotating structure.

[0028] In one embodiment, an advertising machine with a rotating structure includes: a support 100 and a first magnet 204. An advertising machine body 200 is movably disposed above the support 100. A rotating shaft 201 is fixedly connected to the center of one side outer wall of the advertising machine body 200. One end of the rotating shaft 201 is inserted into the interior of the support 100 to drive the advertising machine body 200 to rotate. The first magnet 204 is disposed inside the support 100 and rotates around the rotating shaft 201. A plurality of second magnets 207 are arranged equidistantly in a ring on one side of the rotating shaft 201. The first magnet 204 is magnetically attracted to the plurality of second magnets 207 respectively to limit the position of the advertising machine body 200.

[0029] In this embodiment, the advertising machine body 200 is connected to the bracket 100 via a rotating shaft 201. One end of the rotating shaft 201 is inserted into the bracket 100 and serves as the rotation axis. A first magnet 204 is fixed inside the bracket 100, and its installation position is coaxial with the rotating shaft 201 to ensure that the magnetic attraction direction is stable during rotation. Multiple second magnets 207 are arranged equidistantly in a ring on the side wall of the rotating shaft 201. When the user rotates the advertising machine, the first magnet 204 and different second magnets 207 generate a magnetic attraction effect, forming positioning points distributed at equal angles.

[0030] The magnetic structure achieves stepless adjustment through the magnetic damping effect of the first magnet 204 and the second magnet 207. Users can switch between horizontal and vertical screen modes simply by pushing the advertising machine. The magnetic attraction automatically corrects the offset, avoiding the wear and tear problems of traditional mechanical buckles. The spacing between the multiple second magnets 207 can be adjusted according to the usage scenario. For example, a 15°-30° interval is used in shopping mall wayfinding screens to accommodate viewing from multiple directions, while a 45°-90° interval is used in conference display screens to improve the accuracy of horizontal and vertical screen switching.

[0031] It should be noted that the magnetic strength of the first magnet 204 and the second magnet 207 can be optimized by replacing the magnets with different specifications or by adjusting the distance between the first magnet 204 and the rotating shaft 201. This design takes into account both rotational flexibility and display stability, significantly improving the dissemination effect of advertising content and user experience.

[0032] like Figure 1 , Figure 2 and Figure 3 As shown, a bearing ring 202 is fixedly sleeved on the surface of the rotating shaft 201. The outer wall of the bearing ring 202 is fixed on the inner wall of the bracket 100. A rotating gear 203 is fixedly connected to one end of the rotating shaft 201. A damping gear 400 is meshed on one side of the rotating gear 203. The axis of the damping gear 400 is fixed on the inner wall of the bracket 100 through a fixed shaft.

[0033] In this embodiment, the rolling friction of the bearing ring 202 replaces the sliding friction, which significantly reduces the resistance when the rotating shaft 201 rotates, ensuring that the advertising machine body 200 rotates more smoothly. The damping gear 400 is embedded with a high friction coefficient material, and the damping gear 400 is a relatively mature product in the prior art. The appropriate model can be selected according to the actual use. When the user rotates the advertising machine body 200, the rotating gear 203 drives the damping gear 400 to rotate. The meshing between the gears generates reverse resistance, forming a stepless damping effect.

[0034] The shaft of the damping gear 400 is fixed to the inner wall of the bracket 100 via a fixed shaft to ensure stable operation of the damping system. This design combines magnetic positioning and mechanical damping for dual control. The magnetic system achieves precise angle positioning, while the damping gear 400 prevents the advertising machine from rotating unexpectedly due to external forces. By adjusting the thickness of the friction material of the damping gear 400 or replacing the rotating gear 203 with a different gear ratio, the rotation feel and positioning force can be flexibly adjusted to meet the diverse needs of different usage scenarios.

[0035] like Figure 2 , Figure 3 and Figure 4 As shown, a fixed post 205 is fixedly connected to one end of the rotating gear 203 away from the rotating shaft 201. A support frame 206 is fixedly connected to one side of the fixed post 205. One side of the first magnet 204 is fixed to the support frame 206. A fixed ring 300 is fixedly connected to the inner wall of one side of the bracket 100. A limit ring 301 is fixedly connected to the outer wall of the fixed ring 300 near the bracket 100. The limit ring 301 is sleeved on the surface of multiple second magnets 207 with the rotating shaft 201 as the axis.

[0036] In this embodiment, the rigid connection between the fixed column 205 and the rotating gear 203 ensures that the first magnet 204 rotates synchronously with the rotating shaft 201, maintaining the magnetic alignment accuracy with the second magnet 207. The inner wall of the limiting ring 301 is made of a low-friction coefficient material, which allows the second magnet 207 to rotate smoothly, and prevents the magnet assembly from shifting axially due to centrifugal force through the annular wrapping structure. The dual constraint of the support frame 206 and the limiting ring 301 ensures that the magnetic attraction structure maintains its positioning stability under rotation or external impact. In addition, the fixed ring 300, as a reinforcing structure of the bracket 100, can disperse the stress when the rotating shaft 201 rotates and extend the service life of the overall mechanism.

[0037] like Figure 3 , Figure 4 and Figure 5As shown, the rotating gear 203 and the fixed column 205 are both located inside the bracket 100 and rotate coaxially with the rotating shaft 201. A cover plate 500 is fixedly connected to the end of the fixed column 205 away from the rotating gear 203. The cover plate 500 is at the same horizontal height as the outer wall of the bracket 100 and the fixed ring 300. A pin 501 is fixedly connected to one side of the outer wall of the cover plate 500. Multiple limiting blocks 302 are fixedly connected to one side of the outer wall of the fixed ring 300 at equal intervals. The spacing between the multiple limiting blocks 302 is the same as the spacing between the multiple second magnets 207.

[0038] In this embodiment, the cover plate 500, the bracket 100, and the outer wall of the fixing ring 300 are at the same horizontal level, forming an integrated protective structure. This not only prevents dust from entering the internal mechanical area, but also enhances the aesthetics of the equipment through the integrated design. When the advertising machine body 200 rotates to a preset angle, the pin 501 is inserted between the adjacent limiting blocks 302 to form a mechanical hard limit, which, together with the magnetic positioning, provides double protection. The pin 501 and the limiting block 302 prevent unexpected rotation caused by external force, increasing safety.

[0039] Working principle: When the user rotates the advertising machine body 200, the rotating shaft 201 drives the bearing ring 202 to rotate within the bracket 100. The rotational resistance is reduced by rolling friction. The rotating gear 203 at the end of the rotating shaft 201 rotates synchronously, driving the meshing damping gear 400 to rotate. The high friction material inside the damping gear 400 generates reverse resistance, forming a stepless damping effect, avoiding unexpected rotation caused by external force interference.

[0040] The first magnet 204, fixed on the support frame 206, rotates synchronously with the rotating shaft 201. When it approaches the multiple second magnets 207 on the side wall of the rotating shaft 201, the magnetic attraction causes the first magnet 204 to align with the specific second magnet 207, forming positioning points distributed at equal angles, thus achieving precise angle locking. The limiting ring 301 wraps around the second magnet 207 through its inner wall to prevent axial displacement caused by centrifugal force and ensure magnetic attraction stability.

[0041] When the advertising machine body 200 rotates to the preset angle, the pin 501 on the cover plate 500 is inserted between the limiting blocks 302 of the fixing ring 300 to form a mechanical hard limit, which, together with the magnetic attraction structure, forms a double guarantee. By adjusting the spacing between multiple second magnets 207 or changing the friction material of the damping gear 400, it can be flexibly adapted to different usage environments. This design takes into account both the smoothness of rotation and the reliability of positioning, and significantly improves the advertising display effect.

[0042] It should be noted that the advertising machine body 200 and other components mentioned above are all devices with relatively mature existing technologies. The specific model can be selected according to actual needs. At the same time, the advertising machine body 200 can be powered by a built-in power supply or by AC power. The specific power supply method should be selected according to the situation, which will not be elaborated here.

[0043] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
