Description

A kind of blackboard for Chinese teacher teaching

technical field

The utility model relates to the technical field of blackboards, in particular to a blackboard for teaching Chinese teachers.

Background technique

The blackboard is a necessary educational tool in our education industry. The blackboard can meet the characteristics of multi-person learning and teaching. When the teaching blackboard in the prior art is in use, more chalk dust is easily produced during the process of erasing the chalk by the blackboard eraser, and the chalk dust is easily inhaled into the human body from the respiratory tract, which is not conducive to the health of the teacher, and the existing blackboard The erasing volume is small, and the erasing area is small, and it is time-consuming and laborious for erasing large-area chalk characters.

For example, the Chinese patent whose application number (patent number) is CN202020431345.3 discloses a blackboard for Chinese teaching. The blackboard for Chinese teaching includes a blackboard frame. The inner wall of the chute is fixedly connected with a first writing board, the inner bottom wall of the installation groove is provided with a chute, and the inner bottom wall of the chute is fixedly connected with a support spring; through the blackboard frame, the installation groove, the first writing board, The supporting spring, the second writing board, the Pzi grid and the positioning bolts are set in coordination. When the teacher needs to teach, he can write directly on the first writing board. If teaching radicals and fonts, he can turn it first. Positioning bolts to release the connection between the blackboard frame and the second writing board, and the second writing board will push the second writing board out of the chute under the action of the support spring, so the teacher does not need to draw the rice grid, and directly Teaching can effectively reduce the workload of teachers and improve work efficiency". However, the blackboard still has the problem that when the blackboard is in use, it is easy to produce more chalk dust, which is not conducive to the health of teachers and students. The removal area is relatively small, and it is more time-consuming and labor-intensive for erasing chalk characters in large areas.

Detailed ways

The following describes the implementation of the utility model through specific examples in conjunction with the accompanying drawings.

Embodiment 1: The utility model provides a blackboard for Chinese teacher teaching, as shown in Fig. 1 to Fig. 4 , comprising: a blackboard main body 1, a wiping board assembly 2, a flexible hose 4 and a dust collection box 3.

Specifically, a frame 11 is provided on the outside of the blackboard main body 1, and a partition 13 is provided in the middle of the frame 11, and the four corners of the frame 11 are provided with mounting holes 6, and the inside of the frame 11 is provided with a chute 12, and the chute The inner side of 12 is connected with a wiper assembly 2, the wiper assembly 2 includes a plate frame 22, and the upper and lower ends of the plate frame 22 are connected with guide wheels 21, and the guide wheels 21 are slidably connected to the inside of the chute 12, and the inside of the plate frame 22 An adsorption chamber 23 is provided, and suction holes 24 are provided on both sides of the adsorption chamber 23, and a blackboard eraser 25 is riveted on the rear side of the plate frame 22, and a handle 26 is welded on the front end of the plate frame 22, and a connection is opened on the front end of the plate frame 22. Hole 27, and connecting hole 27 is positioned at handle 26 lower sides, and the outer end of connecting hole 27 is connected with flexible hose 4, and the outer end of flexible flexible hose 4 is connected with dust collection box 3.

In this embodiment, the blackboard main body 1 is fixed on the wall through the installation hole 6 . The chute 12 on both sides of the dividing plate 13 is not connected, which is convenient for the use of the wiping board assembly 2 in partitions. The flexible hose 4 facilitates the free movement of the wiper assembly 2, and after the wiper assembly 2 is reset to the outside, it shrinks automatically and does not take up space.

As a preferred embodiment, the sliding connection between the guide wheel 21 and the chute 12 makes the wiper assembly 2 move more smoothly and labor-saving, and the wiper assembly 2 is as wide as the writing surface of the blackboard main body 1, which is convenient for one-time wiping. Remove more chalk characters.

A vacuum cleaner is arranged inside the dust collection box 3, and the telescopic hose 4 is connected to the suction port of the vacuum cleaner, and the dust collection box 3 is fixed on the lower end of the frame 11 by bolts. The outer side of the dust collection box 3 is provided with a hinged door body, which is convenient for cleaning the chalk dust inside the vacuum cleaner.

The partition 13 divides the blackboard main body 1 into two halves with the same area, and there are two sets of wiper board assemblies 2 located on both sides of the partition 13 . The partition board 13 facilitates the use of the blackboard main body 1 in partitions, and is suitable for reading explanations and font writing specifications in Chinese teaching.

Second magnets 7 are embedded on both sides of the upper end of the partition 13 , and first magnets 5 are embedded on upper corners of the frame 11 , and the first magnets 5 and the second magnets 7 are located in the same vertical plane as the plate frame 22 . By arranging the first magnet 5 and the second magnet 7, it is convenient for the wiper assembly 2 to move to the side of the middle dividing plate 13, or to move to the side of the frame 11, and all of them will be effectively fixed to prevent the guide wheels 21 of the wiper assembly 2 from moving The inside of the chute 12 slides freely to the writing board surface.
