Description

Technical Field

[0001] The utility model belongs to the technical field of display boards, and particularly relates to a display board. Background Art

[0002] Educational display boards are visual tools in the field of education. Through a picture-and-text design, they intuitively display knowledge, information, and teaching concepts. They are commonly used in classrooms, science popularization venues, etc. to promote teaching interaction, enrich learning content, and stimulate students' interest, which is an effective means to improve the educational effect.

[0003] For example, a Chinese patent with the publication number CN220627368U discloses a display board, which includes a first frame board, a second frame board, and a third frame board. The front end of one side of the first frame board is connected to the second frame board through a hinge, and the rear end of one side of the second frame board is connected to the third frame board through a hinge. Universal wheels are installed at both ends below the first frame board, the second frame board, and the third frame board. Installation blocks are fixedly installed at the right end above the first frame board, at the left and right ends above the second frame board, and at the left end above the third frame board, and threaded holes are provided in the middle of the installation blocks. Outer grooves are provided on the surfaces of both ends of the first frame board, and inner grooves are provided on the inner side surface of the first frame board. This display board can be conveniently expanded by using three groups of foldable and retractable frame boards in cooperation with support rods, so as to paste and display quotation sheets of multiple different schemes. At the same time, it also cooperates with the use of installation screws to facilitate the folding and storage of the frame boards.

[0004] The above patent has the following problems:

[0005] There are some disadvantages when using this patent. For example, when using the above device on open land, heavy objects need to be used to press down the base. If the heavy objects are not selected properly or fixed firmly, the overall device may be blown down by the wind. At the same time, the above device may be maliciously damaged during use, resulting in damage to the displayed content and a decrease in clarity, thereby affecting its aesthetics and the effectiveness of information transmission. In view of this, we propose a display board. Summary of the Utility Model
