Description

A support frame for visual communication

Technical Field

The utility model relates to the technical field of visual communication, in particular to a support frame for visual communication.

Background technique

Visual communication design is a design that is expressed and communicated to the audience through visual media, reflecting the era characteristics of design, graphic design and rich connotations. With the continuous development of the times, visual communication has gradually entered people's lives, but visual communication is very unfamiliar to most people, so the support frame used to display visual communication is very important. The existing support frame or display device usually only adjusts the angle of the displayed work so that people can watch it from multiple angles.

For example, the Chinese patent with publication number CN216494565U, entitled "A multi-angle display device for visual communication design", allows the display stand to rotate smoothly through the coordination between the base, connecting shaft, gearbox, drive motor and support frame, and finally adjusts the angle of the work, which to a certain extent avoids the situation where people need to rotate around the exhibits when viewing the exhibits, and people fall due to crowding. However, when the display device of this patent is in use, the work is placed on the display stand and cannot be adjusted horizontally. In addition, the size of the display stand is limited. When visitors around the display board need to view the work up close, they can only crowd around the display stand. Therefore, there are still problems of crowding and people falling.

The technical solution of the utility model is further described below through the accompanying drawings and embodiments.

In conjunction with Figures 1 to 3, the utility model provides a support frame for visual communication, including a base 1, a fixed frame 2 is provided on the base 1, a display stand 3 is rotatably connected to the fixed frame 2, the display stand 3 is a hollow quadrangular platform structure, and a display cover 4 is provided on the four outer sides of the display stand 3. The inner cavity of the display stand 3 is provided with a driving motor 5, and the output end of the driving motor 5 is connected to a first screw rod 6 through a transmission mechanism 15, and the end of the first screw rod 6 away from the driving motor 5 is connected to a first bevel gear 7, and the two sides of the first bevel gear 7 are respectively meshed with a second bevel gear 8 and a third bevel gear 9, and the second bevel gear 8 and the third bevel gear 9 are jointly meshed with a fourth bevel gear 10, and the second bevel gear 8, the third bevel gear 9 and the fourth bevel gear 10 are all connected to a second screw rod 11, and the first screw rod 6 and the three second screw rods 11 are all threadedly connected to a moving block 12, and a connecting rod 13 is fixedly provided on the top of the moving block 12, and the other end of the connecting rod 13 passes through the side wall of the display stand 3 and is fixedly connected to the display cover 4.

In this embodiment, the connecting rod 13 is an L-shaped rod. When working, the driving motor 5 drives the first screw rod 6 to rotate through the transmission mechanism, and the first screw rod 6 drives the first bevel gear 7 to rotate. The first bevel gear 7 rotates while driving the second bevel gear 8 and the third bevel gear 9 meshed therewith to rotate. The second bevel gear 8 and the third bevel gear 9 rotate while driving the fourth bevel gear 10 meshed therewith to rotate, and finally the first screw rod and the three second screw rods rotate together, and the four screw rods rotate while driving the four moving blocks 12 to move horizontally. When the moving blocks 12 move horizontally, they drive the display cover 4 connected to the connecting rod 13 to move horizontally, so that the displayed works can be moved away from the display stand, and the display range of the works is expanded, avoiding the problem that people can only crowd around the display stand to watch due to the limited size of the display stand, resulting in crowding and people falling.
