Problems solved by technology
[0003] There are currently movable teaching boards on the market. The usual structure is to fix the teaching board on a movable base to realize the moving function of the teaching board. However, the existing mobile bases usually do not have the shock absorption function. When the teaching board During the process of moving and using the teaching, vibration will occur, which not only affects the stability of the teaching board, but also affects the teaching effect during use
The structure of most teaching boards is a common board structure, and the adjustment of the teaching board cannot be realized, thus limiting the practicability of the teaching board and affecting the teaching efficiency

The invention discloses an adjustable combined type movable teaching board convenient for operation and demonstration and belongs to the technical field of teaching appliances. The adjustable combinedtype movable teaching board convenient for operation and demonstration comprises a base; a teaching board rotating mechanism is arranged on the upper side of base; a cavity is formed in the base andthe inner cavity is internally provided with a drive mechanism for driving the teaching board rotating mechanism to rotate; and shock absorption movable devices are arranged around the lower side of the base. A shock absorption function on the whole teaching board in a moving process can be realized, a shocking phenomenon caused in the moving and using process can be avoided efficiently, the teaching effect is ensured, the teaching efficiency is increased efficiently as six expandable teaching boards arranged in a hexagonal manner can be rotated in the teaching process, the height of each expandable teaching board can be changed flexibly by upwards pulling inner boards, and accordingly the adjustable combined type movable teaching board convenient for operation and demonstration is adaptive to teaching materials or tools different in size and the practicability is greatly improved.
Description
technical field [0001] The invention relates to the technical field of teaching equipment, in particular to an adjustable and combined mobile teaching board which is convenient for operation demonstration. Background technique [0002] The teaching board is the utensil used for writing demonstrations in the education industry. Usually, the teaching board is a board placed in a classroom or a meeting room, and the content is written with chalk or water-based pen to play the role of explaining and demonstrating. Teaching aids are the general term for all kinds of utensils used by students to intuitively and visually understand the teaching content and the utensils used by teachers in teaching, referred to as teaching aids. Teaching aids can improve students' interest in learning, enrich perceptual knowledge, help form clear concepts, and develop students' observation and thinking skills. [0003] There are currently movable teaching boards on the market. The usual structure i...
