Problems solved by technology

[0003] The function of the teaching board in the prior art is comparatively simple, can only realize the function of writing, but can not realize other functions, and this has just caused the teacher to have more inconvenience in the teaching process, such as: when the teacher writes on the blackboard in the classroom Finally, the chalk on the blackboard needs to be erased. If a traditional blackboard eraser is used, the workload will be larger and more precious time in the classroom will be wasted; the angle of the existing teaching board cannot be adjusted, and its use effect is poor; in addition, when needed When displaying some albums to students, the existing teaching board is very inconvenient to hang; due to the large font on the blackboard, the content displayed on the teaching board at the same time is less, and it is difficult to store if the teaching board is enlarged; in the prior art, teaching The height of the board is generally adjusted through the limit hole. The adjustment is graded and cannot be stopped at any desired height at will, which has certain limitations.

Abstract

A teaching board for teaching with a height locking function, comprising a support board, the underside of which is provided with a height locking device; As for the hinge, the rear side of the support plate is provided with a second hinge, the second hinge is fixedly connected with a threaded sleeve, the threaded sleeve is arranged obliquely, and the internal thread of the threaded sleeve is connected with a screw rod. The beneficial effect of the present invention is that the height locking device is used to lock the rotating shaft, so that the height of the support plate is kept at the required height and the use effect is improved; when the screw is rotated, the screw pulls or pushes the plate body backward or forward , so that the board rotates around the shaft, changing the inclination angle of the board, which is convenient to use, and can also solve the problem of unclear fonts caused by the reflection of the board; pull out the hidden board when using it, and you can continue to write on the hidden board , When not in use, push the hidden board in, reducing the overall volume of the teaching board.

Description

technical field [0001] The invention relates to the technical field of teaching boards, in particular to a teaching board with a height locking function. Background technique [0002] Teaching board, that is, the utensils used for writing demonstrations in the education industry. Usually, teaching boards are boards placed in classrooms or conference rooms. The content is written with chalk or water-based pens to play the role of explaining and demonstrating. Therefore, the importance of teaching boards in the classroom is self-evident. [0003] The function of the teaching board in the prior art is comparatively simple, can only realize the function of writing, but can not realize other functions, and this has just caused the teacher to have more inconvenience in the teaching process, such as: when the teacher writes on the blackboard in the classroom Finally, the chalk on the blackboard needs to be erased. If a traditional blackboard eraser is used, the workload will be la...
