Technical Field

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

[0002] Display boards are usually used to describe a flat or three-dimensional structure used to display information, pictures, artwork or other visual materials. Display boards can be used in a variety of occasions and environments, such as schools, offices, exhibition halls, shops, etc.

[0003] The patent network announcement number CN213634979U discloses a teaching display board. The purpose of this utility model is that it has a simple structure, is easy to use, can be used on both sides, and can also fine-tune the left and right angles to avoid direct sunlight.

[0004] However, the above-mentioned display board is not easy to disassemble and assemble during the teaching process. When it needs to be stored and transported, it needs to be stored and transported over a large area as a whole. A large area is temporarily used during storage and it is not easy to transport. Therefore, improvement is needed. Utility Model Content

[0013] Preferably, a notch is provided at the bottom of the second U-shaped clamping plate corresponding to the stabilizing rod, and the second U-shaped clamping plate is slidably connected to the surface of the stabilizing rod through the notch.

[0014] Compared with the prior art, the utility model provides a teaching display board, which has the following beneficial effects:

[0015] 1. The teaching display board, through the fastening mechanism provided, drives the rotation of the worm by rotating the fastening button. The rotating worm, in cooperation with the worm wheel, can rotate the rotating rod, so that the gear can drive the first rack and the second rack to approach and move away from each other. When the first rack and the second rack are close to each other, the first clamping piece and the second clamping piece can be driven to approach each other to clamp the board body, so as to achieve the purpose of rapid installation. When the first rack and the second rack are in principle with each other, on the contrary, the first clamping piece and the second clamping piece are driven to move away from each other to contact the board body in a clamping state, so as to achieve the purpose of rapid disassembly.
