Description

a teaching blackboard

technical field

The utility model relates to the technical field of teaching supplies, in particular to a teaching blackboard.

Background technique

Teaching is a human-specific talent cultivation activity composed of teachers' teaching and students' learning. Through such activities, teachers guide students to actively and consciously learn and accelerate the mastery of basic cultural and scientific knowledge and basic skills with a purpose, in a planned and organized manner, and promote the comprehensive improvement of students' various qualities, so that they can become the people needed by society. The concept of teaching is abstracted and generalized from teaching phenomena and teaching practice, and the connotation of teaching also develops with the development of history.

The blackboard does not specifically refer to the black board surface. In the traditional sense, it is a plane that can be written repeatedly. The board surface is hard and is mostly used for teaching. The blackboard is indispensable in the teaching process. When the existing blackboard needs to be pushed and pulled after writing, the blackboard eraser is generally used to push and pull it. This requires teachers or students to push and pull the blackboard many times. This is not only labor-intensive, but also low efficiency. , At the same time, the dust generated in the process of pushing and pulling will cause harm to the teacher or the student's body.

Utility model content

The purpose of the utility model is to provide a teaching blackboard in order to overcome the deficiencies of the prior art.

The utility model is realized through the following technical solutions:

A teaching blackboard, comprising a blackboard body in a rectangular structure, on which a vertically arranged push-pull plate is arranged, the upper end of the push-pull plate is connected with a slider arranged on the upper side of the blackboard body, and the slider is connected to the upper side of the blackboard body. Horizontally arranged drive screws are connected, one end of the drive screw is connected to the drive motor, the lower end of the push-pull plate is provided with at least two guide wheels, the guide wheels are located in the chute on the lower side of the blackboard body, and the push-pull plate A wiping board is provided on the surface near the blackboard body, and a wiping cloth is provided on the wiping surface of the wiping board.

As a preferred technical solution of the utility model, the driving motor is a bidirectional motor.

As a preferred technical solution of the utility model, the wiping plate and the push-pull plate are fixedly connected.

As a preferred technical solution of the utility model, the wiping cloth and the wiping board are connected by sticking.

Compared with the existing technology, the beneficial effects of the utility model are: the utility model is simple in structure and reasonable in design. The utility model is provided with a push-pull plate, a slider, a drive screw and a drive motor, so that when wiping is required, the drive motor Realize the rotation of the driving screw, move the slider to one side, and move the push-pull plate to one side to wipe the blackboard with the wiping cloth, so that the wiping speed is fast, the effect is good, and the labor intensity is small, and at the same time, dust generated during the wiping process is avoided bodily harm to teachers or students.

Detailed ways

In order to make the purpose, technical solution and advantages of the utility model clearer, the utility model will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model, and are not intended to limit the utility model.

Please refer to Fig. 1 and Fig. 2, Fig. 1 is a schematic structural diagram of the utility model; Fig. 2 is a schematic diagram of the wiping structure in Fig. 1 .

A teaching blackboard, comprising a blackboard body 1 in a rectangular structure, on which a vertically arranged push-pull plate 2 is arranged, and the upper end of the push-pull plate 2 is connected with a slider 3 arranged on the upper side of the blackboard body 1 , the slider 3 is connected to a horizontally arranged driving screw 4, and one end of the driving screw 4 is connected to a driving motor 5, wherein the driving motor 5 is a bidirectional motor, so that rotation in two directions is realized.

The lower end of the push-pull plate 2 is provided with at least two guide wheels 6, the guide wheels 6 are located in the chute 101 on the lower side of the blackboard body 1, and the surface of the side of the push-pull plate 2 close to the blackboard body 1 is provided with a wiping plate 7, wherein the wiping plate 7 is fixedly connected to the push-pull plate 2. The wiping surface of the wiping board 7 is provided with a wiping cloth 8, wherein the wiping cloth 8 and the wiping board 7 are glued together, so that the wiping cloth 8 can be cleaned or replaced. When needing to wipe like this, drive motor 5 realizes the rotation of driving screw rod 4, realizes slide block 4 to move to one side, push-pull plate 2 is moved to one side and realizes wiping cloth 8 to wipe blackboard, and wiping speed is fast like this, and effect is good, At the same time, the labor intensity is small, and the dust generated in the wiping process is avoided from injuring teachers or students.

The above descriptions are only preferred embodiments of the present utility model, and are not intended to limit the present utility model.
