Abstract

The invention discloses a teaching appliance capable of performing multi-degree-of-freedom adjustment on a board frame. The teaching appliance comprises a writing panel and a multi-degree-of-freedom adjusting bracket matched with the writing panel for use. The multi-degree-of-freedom adjusting support comprises a base, a lifting adjusting device and a supporting rod. A moving device is mounted atthe bottom of the base; the lifting adjusting device is mounted on the base; the supporting rod is rotatably and adjustably arranged on the lifting adjusting device through the rotating device; and the writing panel is arranged on the supporting rod in a universal adjusting mode through the universal adjusting device. Specifically, the lifting adjusting device comprises a lifting supporting base,a lifting movable plate and a driving assembly. The rotating device comprises a clamping base and a rotating plate. The writing panel comprises a panel device and a cleaning device matched with the panel device. By means of the teaching appliance capable of conducting multi-degree-of-freedom adjustment on the plate frame, adverse effects of environmental factors in the teaching process are weakened, and a better teaching effect is achieved.

Description

technical field [0001] The invention relates to the field of teaching appliances, in particular to a teaching appliance capable of multi-degree-of-freedom adjustment of a board frame. Background technique [0002] In the traditional teaching mode, teaching tools for writing are indispensable. Traditional writing utensils are often fixed on the wall, such as a traditional classroom blackboard. During use, such writing utensils are often affected by environmental factors, such as the writing panel is reflected by light, the writing panel is too inclined relative to the user's viewing angle due to space constraints, and the like. These phenomena will hinder the normal use of users and affect the teaching effect. Therefore, how to design a teaching tool capable of multi-degree-of-freedom adjustment to the board frame, weaken the impact of the teaching tool from environmental factors, and achieve a better teaching effect is a technical problem that technicians in this field nee...
