Description

Technical Field

[0001] The utility model relates to the technical field of display boards, in particular to a project display board. Background Technique

[0002] Landscape construction refers to creating a landscape space with ornamental, leisure, and entertainment functions within a certain area by using elements such as plants, water bodies, terrain, and buildings according to design plans and aesthetic principles. This process includes design, planning, construction, and post-maintenance. Landscape construction aims to create a beautiful and pleasant environment, improve people's quality of life, and also protect the natural environment and increase ecological functions. During landscape construction, project display boards need to be installed to show the achievements and progress in the landscape design, planning, and construction processes to the public.

[0003] However, the existing project display boards have fixed structures, occupy a large amount of space, are not convenient for storage and transportation, and in order to facilitate people's viewing, the display boards are at a certain height from the ground, resulting in people often needing to use tools such as stools when replacing posters. Standing on a stool to replace posters is somewhat dangerous and there is a risk of falling. Content of the Utility Model

[0004] The purpose of the utility model is to provide a project display board that is convenient for storage and convenient for replacing posters.

[0005] To achieve the above purpose, the technical solution of the utility model is as follows.

[0006] A project display board includes a main display board and a bottom board. Side plates are installed on both side surfaces of the main display board. Threaded holes are provided inside both side plates. Rotating rods are rotatably connected to both sides of the upper surface of the bottom board, and the rotating rods are threadedly connected to the threaded holes, and the bottom of the rotating rods penetrates to the inside of the bottom board. A driving mechanism capable of simultaneously driving the two rotating rods to rotate is provided inside the bottom board. Slots are provided on both side surfaces of the main display board, and auxiliary display boards are slidably installed inside the slots.

[0007] Thus, through the setting of the auxiliary display board, the display area can be expanded. When the auxiliary display board is inserted into the slot, the horizontal length of the display board can be reduced. Due to the setting of the rotating rod and the threaded hole, when the two rotating rods are simultaneously driven to rotate by the driving mechanism, the main display board can be driven to rise and fall. By lowering the main display board to the lowest position, the height of the display board can be reduced, so as to achieve the purpose of reducing the occupied space, being convenient for storage and transportation, and when replacing posters, the main display board can be lowered by the driving mechanism, so that the staff can replace the posters on the main display board and the auxiliary display board while standing on the ground, avoiding the risk of falling due to working at heights.

[0008] Further, the driving mechanism includes a rotating shaft rotatably installed inside the bottom plate. Worms are installed on the outer surfaces of both sides in the length direction of the rotating shaft. Worms are installed on the lower ends of both threaded rods, and the worms are meshed with the worm wheels.

[0009] When the rotating shaft rotates, the two worms on its surface also rotate accordingly. Due to the meshing relationship between the worm and the worm wheel, the worm wheel can drive the threaded rod to rotate, achieving the purpose of driving the main display board to rise and fall. Moreover, the worm and the worm wheel have good self-locking properties, which can ensure the stability of the main display board.

[0010] Further, one end of the rotating shaft penetrates to the outside of the bottom plate and a disc is installed. A handle is connected to a side of the outer surface of the disc far from its center.

[0011] Through the setting of the disc and the handle, it is convenient to rotate the rotating shaft.

[0012] Further, U-shaped plates are installed on both sides of the upper surface of the bottom plate, and the U-shaped plates are arranged outside the threaded rods.

[0013] Through the setting of the U-shaped plates, on the one hand, the inner walls play a limiting role on the side plates, which can improve the stability of the main display board during rising and falling. On the other hand, they can also block the threaded rods, making the overall structure more beautiful.

[0014] Further, limiting grooves are opened on the inner walls of the U-shaped plates, and limiting blocks are installed on the outer surfaces of the side plates, and the limiting blocks are arranged in the limiting grooves.

[0015] Through the setting of the limiting grooves and the limiting blocks, the rising height of the side plates can be restricted, avoiding the risk of the side plates falling off the threaded rods and causing injury.

[0016] Further, a handle is installed on the side surface of the secondary display board, and a fastening bolt for fixing the secondary display board is installed on the rear side surface of the main display board.

[0017] Through the setting of the handle, it is convenient to pull the secondary display board. And by tightening the fastening bolt so that its end abuts against the surface of the secondary display board, the position of the secondary display board can be fixed. BRIEF DESCRIPTION OF THE DRAWINGS
