[0001] The utility model relates to the technical field of propaganda frame, specifically is a kind of exhibition propaganda frame. BACKGROUND

[0002] With the rapid development of exhibition industry, the demand and application scene of propaganda frame as important information dissemination medium are also growing. Although the traditional propaganda frame meets the basic display requirements to some extent, there are obvious limitations in flexibility and adaptability, especially for the scene needing frequent size adjustment to adapt to different display space or content change, the existing propaganda frame mostly adopts fixed structure design, cannot be flexibly adjusted according to actual demand, which limits the display environment of propaganda frame. SUMMARY

[0003] The technical problem to be solved by the utility model is how to make the exhibition propaganda frame can be flexibly adjusted according to propaganda poster to meet the needs of different display environment and content.

[0004] The technical scheme employed by the utility model is: an exhibition propaganda frame, including chuck and first support rod, the chuck is internally provided with first rotating shaft, the first rotating shaft is rotatably connected with first rotating lever and second rotating lever, one side of the chuck is provided with first through hole and second rotating shaft, wherein the first through hole is connected with first locking knob, and one end of the first locking knob is rotatably connected with the first rotating shaft, the first rotating shaft is installed with locking disc for locking the side wall of the first rotating lever and the second rotating lever, the locking disc is pushed by the first locking knob, the second rotating shaft is rotatably connected with first rotating piece, the first rotating lever and the second rotating lever and the first rotating piece are connected with the first support rod.

[0005] After adopting the above structure, the following beneficial effects are obtained:

[0006] (1) by setting first rotating shaft in chuck, and making first rotating lever and second rotating lever rotatably connected with first rotating shaft, the exhibition propaganda frame can be flexibly adjusted according to actual display requirement Angle of propaganda material, and different types of propaganda material are used, effectively guarantee that the exhibition propaganda frame is adjusted according to different display requirements Flexibility, greatly expand the use range of exhibition propaganda frame.

[0007] (2) The first through hole is connected with the first locking knob. When the first locking knob is rotated, the locking disc installed on the first rotating shaft is pushed. With the continuous pushing of the locking disc by the first locking knob, the locking disc finally tightly fits with the side wall of the first rotating rod and the second rotating rod, so that the first rotating rod and the second rotating rod are locked, ensuring that the advertising rack can maintain the set angle unchanged even if there is slight external force, and enhancing the reliability of use.

[0008] (3) The locking part of the first rotating rod and the second rotating rod is designed in the interior of the chuck, which is compact in structure and does not occupy extra space, and is simple and intuitive to operate. Only the first locking knob needs to be rotated to complete the angle adjustment and locking, without the need for complex tools, thereby improving the use convenience of the exhibition advertising rack.

[0009] As a preferred, one side of the chuck is provided with a second through hole, the second through hole is slidably connected with a locking bolt, the locking bolt passes through the first rotating part, and the locking bolt is connected with a second locking knob for locking the first rotating part.

[0010] By providing a second through hole on one side of the chuck and slidably connecting a through hole with the first rotating part, the first rotating part can linearly move within a certain range, so that the exhibition advertising rack can be adjusted according to specific display requirements. The second locking knob connected with the locking bolt can fix the locking bolt at the current position by rotating the second locking knob after the adjustment of the first rotating part is completed, so as to ensure that the first rotating part will not be displaced due to external force. This design can quickly adjust the first rotating part, and also makes the overall structure of the exhibition advertising rack more flexible.

[0011] As a preferred, one side of the chuck away from the first locking knob is provided with a boss, the boss is rotatably connected with a second rotating part, and the boss is provided with a third locking knob passing through the boss and the second rotating part.
