Description

A writing whiteboard for education and training

Technical Field

The utility model belongs to the technical field of writing whiteboards, in particular to a writing whiteboard for education and training.

Background Art

A writing whiteboard is a writing surface, usually made of white metal plate material. The function of a whiteboard is similar to that of a blackboard. It is a repeatedly erasable writing tool, usually used for teaching, conference discussions, or personal and family notes. Because whiteboards are easy to move and clean, they are widely used in teaching and training. Usually, writing whiteboards are placed in classrooms or conference rooms, and content is written with whiteboard pens to serve as explanations and demonstrations.

At present, the existing writing whiteboard has a relatively simple structure and is mostly a fixed structure. The height of the writing whiteboard cannot be flexibly adjusted according to actual usage. During the education and training process, it is easy for people sitting in the back row to not be able to see the writing on the whiteboard, affecting the teaching and training effect. At the same time, when the content on the writing whiteboard is explained, the training personnel need to manually erase the writing on the whiteboard with the help of an eraser, which is relatively laborious and has a poor use effect.

In view of the above problems, we propose a writing whiteboard for education and training.

The screw rod 5 cooperates with the thread of the support block 4 on the left side to facilitate the up and down movement of the support block 4 on the left side, thereby driving the up and down movement of the first writing board 2 to achieve the purpose of adjusting the height of the first writing board 2 and adapt to different places of use. When the first writing board 2 is adjusted to move up to the highest point, the second writing board 10 is exposed, which effectively increases the writing area. There is no need to frequently erase the written content, which is convenient for use. At the same time, under the action of the electric push rod 7, it is convenient to push the mounting plate 8 to move backward, thereby driving the whiteboard eraser 9 to move backward close to the first writing board 2. In the process of adjusting the first writing board 2 to move up and down, the content written on the first writing board 2 is erased without manual erasing, which is convenient for use.

A shell 11 is provided at the bottom of the fixed plate 1, and a plurality of partitions 12 are fixed inside the shell 11. A shell door 15 is movably installed at the front port of the shell 11 through a hinge. The plurality of partitions 12 can be used to divide the inner cavity of the shell 11 into a plurality of cavities, so as to facilitate the placement and storage of writing pens, whiteboard erasers and whiteboard vacuum cleaners, and facilitate their use.

A first motor 13 is installed on the left side inside the shell 11. The output shaft of the first motor 13 passes through the shell 11 and the fixed plate 1 and is fixedly connected to the lower end of the screw rod 5. A sliding rod 14 is arranged inside the movable groove 3 on the right side. The sliding rod 14 passes through the support block 4 on the right side, and the support block 4 on the right side slides with the sliding rod 14.

Brackets 16 are fixed to the left and right surfaces of the fixed plate 1, a base 17 is fixed to the bottom of the bracket 16, a plurality of self-locking universal wheels 18 are installed on the lower surface of the base 17, a handle 19 is fixed to the upper side of the side of the bracket 16 away from the fixed plate 1, and an anti-slip cover is provided on the handle 19, through the joint action of the handle 19, the bracket 16, the base 17 and the self-locking universal wheels 18, the overall movement of the writing whiteboard is facilitated.

The adjusting mechanism includes a slide groove 20, a screw rod 21, a second motor 22 and a guide rod 23. The two slide grooves 20 are relatively opened on the front sides of the left and right surfaces inside the groove. The screw rod 21 is arranged inside the slide groove 20 on the left side, and the guide rod 23 is arranged inside the slide groove 20 on the right side. A slider is threadedly arranged on the screw rod 21, and a guide block is slidingly sleeved on the guide rod 23. The slider and the guide block are relatively fixed on the left and right surfaces of the support frame 6. The second motor 22 is arranged on the front side of the first motor 13, and the output shaft of the second motor 22 is connected to the lower end of the screw rod 21.

Example:

When in use, first, under the joint action of the handle 19, the bracket 16, the base 17 and the self-locking universal wheel 18, the writing whiteboard is adjusted to move to a suitable position and fixed. During the education and training process, the educational content is written and displayed through the first writing board 2;

When the height of the first writing board 2 needs to be adjusted, the first motor 13 is started to drive the screw rod 5 to rotate. Under the thread cooperation between the screw rod 5 and the left support block 4, combined with the sliding cooperation between the right support block 4 and the slide rod 14, the first writing board 2 is driven to move upward to a suitable height to adapt to the actual use place, which solves the problem that most existing writing whiteboards are fixed structures and the height of the writing whiteboard cannot be adjusted according to the actual use situation. During the education and training process, it is easy to cause the people sitting in the back row to be unable to see the writing content on the whiteboard, affecting the teaching and training effect;

When the first writing board 2 is adjusted to move up to the highest position, the second writing board 10 is exposed, which effectively increases the writing area and facilitates use;

When erasing the written content on the second writing board 10, the electric push rod 7 is started, and under the action of the mounting plate 8, the whiteboard eraser 9 is pushed to move backward until it contacts the second writing board 10, and at the same time, the second motor 22 is driven to drive the screw 21 to rotate. Under the thread cooperation between the screw 21 and the slider, combined with the sliding cooperation between the guide block and the guide rod 23, the support frame 6 is driven to move up and down stably, and then the whiteboard eraser 9 is driven to move up and down close to the second writing board 10 to erase the written content on the second writing board 10;

When erasing the written content on the first writing board 2, the electric push rod 7 and the mounting plate 8 cooperate with each other to adjust the whiteboard eraser 9 to contact the front surface of the first writing board 2, and at the same time drive the first motor 13 to rotate in the opposite direction, drive the first writing board 2 to move downward, and then erase the written content on the surface of the first writing board 2 by the whiteboard eraser 9, which solves the problem in the prior art that after the content on the writing whiteboard is explained, the training personnel need to manually erase the handwriting on the whiteboard with the help of the eraser, which is quite laborious;

When part of the written content needs to be erased, the educator can use an eraser to manually erase it.

It should be further explained that the installation structure, connection method or setting method of each component in the utility model are all common mechanical methods, and they can be implemented as long as they can achieve their beneficial effects. At the same time, the electric push rod 7, the first motor 13 and the second motor 22 in the utility model are all purchased on the market, and technical personnel in this field can install and use them as required.

All technical features in this embodiment can be freely combined according to actual needs.
