Combined type teaching plate

Abstract

The invention discloses a combined type teaching plate which comprises a writing device and a supporting device, wherein the writing device comprises a supporting plate and a base plate; clamping buckles are arranged at center positions of the upper, lower, left and right ends of the front end face of the supporting plate; a writing board is arranged on the front side face of the supporting plateand is clamped with the supporting plate through the clamping buckles; the supporting device comprises two cylindrical telescopic rods and two landing legs; the two telescopic rods are arranged on therear side face of the supporting plate; the two landing legs are arranged at the bottom ends of the two telescopic rods; and an angle adjusting device is arranged between the telescopic rods and thesupporting plate. The combined type teaching plate is simple in structure and convenient to mount and carry; and height and inclination angle of the teaching plate can be adjusted according to demandsof the actual situation, so that the combined type teaching plate is comfortable in writing, simple and convenient to move and deserves popularization.

Description

technical field [0001] The invention relates to the technical field of teaching tools, in particular to a combined teaching board. Background technique [0002] The teaching board is an appliance used for writing demonstrations in the education industry. The teaching board was originally a blackboard. The traditional blackboard is to apply simple black paint on the surface of a hard object such as a flat wooden board or cement board, and use it after the black paint dries. Chalk writing, although the cost of the blackboard is low, the corrosion resistance of the blackboard is poor. Long-term use will cause the surface of the blackboard to be uneven, and it is difficult to repair after damage. Moreover, the surface of the blackboard is very reflective and easy to fade. It needs to be repainted after a period of time; the traditional blackboard for teaching is gradually being eliminated and replaced, and the product after the rise of new materials is the whiteboard, which is u...

[0002] The teaching board is an appliance used for writing demonstrations in the education industry. The teaching board was originally a blackboard. The traditional blackboard is to apply simple black paint on the surface of a hard object such as a flat wooden board or cement board, and use it after the black paint dries. Chalk writing, although the cost of the blackboard is low, the corrosion resistance of the blackboard is poor. Long-term use will cause the surface of the blackboard to be uneven, and it is difficult to repair after damage. Moreover, the surface of the blackboard is very reflective and easy to fade. It needs to be repainted after a period of time; the traditional blackboard for teaching is gradually being eliminated and replaced, and the product after the rise of new materials is the whiteboard, which is usually used in conference rooms and multimedia teaching rooms. The frequency of use in the actual teaching work environment is relatively low, mainly due to the following problems in the use of whiteboards: 1. The existing whiteboards for teaching are usually fixed on the wall and cannot be moved arbitrarily during use. The angle of the whiteboard cannot be changed at will according to the demand, and due to the reason of light, the content in some ranges on the whiteboard often cannot be seen clearly by the students, so the available space on the whiteboard is greatly reduced; With an integrated structural design, often the height of the whiteboard cannot be adjusted after it is set on the wall of the classroom, and the height of each teacher is different. Half part is used for writing, which also greatly reduces the available space of the whiteboard; 3. The existing whiteboard for teaching has a stand-type whiteboard, but the existing stand-type whiteboard is usually an integrated structure, which is inconvenient to install and disassemble. This brings a lot of trouble to the carrying and transportation of the teaching board
