Description

A Chinese-Korean bilingual teaching device

technical field

The utility model relates to the field of teaching appliances, in particular to a Chinese-Korean bilingual teaching device.

Background technique

At present, Korean teaching is a combination of Chinese and Korean bilingual teaching. Usually, teachers write Korean and Korean corresponding Chinese meanings on the teaching board for explanation. When teachers test the classroom teaching effect, they usually need to cover up the Chinese meanings. Test students' newly learned Korean results. However, Korean and Chinese are located on the same teaching board, and the teaching board has a large area, so it is difficult to block. In addition, teachers are all holding microphones to explain, which brings inconvenience to teaching work. This is the weak point of prior art.

Invention content:

The technical problem to be solved by the utility model is to provide a Chinese-Korean bilingual teaching device, which can write Korean and Chinese on different writing boards, which is convenient for teaching, and realizes that the microphone can follow the teacher to move at any time.

The utility model adopts following technical scheme to realize the object of the invention:

A Chinese-Korean bilingual teaching device, comprising a support frame, characterized in that: one side of the support frame is connected with a set of connecting rods, one end of a writing board is hinged on each of the connecting rods, and the other end of the writing board A groove is provided, and a cooperating bump is arranged in the groove, the bump is connected to the telescopic shaft, the telescopic shaft passes through the support frame, and compression springs are arranged on the upper and lower sides of the telescopic shaft, The top of the compression spring just bears against the protrusion.

As a further limitation to the technical solution, the underside of the support frame is provided with a gear guide rail, and the gear guide rail is engaged with a rolling gear, and the rolling gear is connected to the output shaft of the mobile motor, and the mobile motor is connected to the universal tube , the universal tube connects the microphone.

As a further limitation to the technical solution, the bump is a cuboid.

As a further limitation to the technical solution, one end of the telescopic shaft is connected to a pull block.

Compared with the prior art, the advantages and positive effects of the utility model are: the support frame of the utility model is used to support the writing board, the writing board is hinged on the connecting rod, and can rotate around the connecting rod, that is, one side of the writing board can be hidden The content of the writing board can also be used on both sides. The protrusion can be nested into the groove to realize the fixing of the writing board. Pull the telescopic shaft, and the protrusion is pulled out of the groove to realize the rotation of the writing board. At this time, the compression When the spring is in a compressed state, the telescopic shaft is released, and the projection is pressed into the groove under the action of the elastic force of the compressed spring, so as to realize the fixing of the writing board. The moving motor can move left and right along the gear guide rail, thereby driving the microphone to move left and right, which is convenient for adjusting the position of the microphone according to the position of the teacher. The universal tube can adjust the orientation and height of the microphone at will, which is convenient for teachers to use. The utility model has a novel concept, can realize Chinese and Korean bilingual teaching, and can also realize random adjustment of the microphone according to the position of the teacher, thereby reducing the teaching burden of the teacher.

Detailed ways:

Below in conjunction with embodiment, further illustrate the utility model.

Referring to Fig. 1, the utility model comprises support frame 1, and one side of described support frame 1 is connected with a group of connecting rods 2, and one end of a writing board 3 is hinged on each connecting rod 2, and each writing board 3 The other end of the groove 13 is provided with a groove 13, and the protrusion 4 is arranged in the groove 13, and the protrusion 4 is connected to the telescopic shaft 5, and the telescopic shaft 5 passes through the support frame 1, and the telescopic shaft 5 passes through the support frame 1. Compression springs 6 are arranged on the upper and lower sides of the shaft 5 , and the top of the compression spring 6 just bears against the protrusion 4 .

The lower side of the support frame 1 is provided with a gear guide rail 7, and the gear guide rail 7 is meshed with a rolling gear 8, and the rolling gear 8 is connected to the output shaft of the mobile motor 9, and the mobile motor 9 is connected to the universal pipe 10 , the universal tube 10 is connected to the microphone 11 . The cooperation of the gear guide rail 7, the rolling gear 14 and the moving motor 9 is all prior art, so it is not repeated here. The universal pipe 10 is also made of materials with certain hardness and flexibility, such as flexible steel pipes, etc., which will not be repeated here.

The bump 4 is a cuboid.

One end of the telescopic shaft 5 is connected with a pull block 12 .

The support frame of the utility model is used to support the writing board 3, the writing board 3 is hinged on the connecting rod 2, and can rotate around the hinged connecting rod 2, when writing, Korean can be written on a writing board 3, and the corresponding Chinese meaning Write on another writing board 3. During the test, just reverse the writing board 3 with Chinese meaning to the back, that is, the content on one side of the writing board 3 can be hidden, and the double-sided use of the writing board 3 can also be realized. The block 4 can be nested into the groove 13 to fix the writing board 3, pull the telescopic shaft 5, and the protrusion 4 is pulled out of the groove 13 to realize the rotation of the writing board 3. At this time, the compression spring 6 is in a compressed state. Loosen the telescopic shaft 5, and the projection 4 is pressed into the groove 13 under the elastic force of the compression spring 6, so as to realize the fixing of the writing board 3. By controlling the rotation direction of the mobile motor 9, the mobile motor 9 can move left and right along the gear guide rail 7, thereby driving the microphone 11 to move left and right, which is convenient for adjusting the position of the microphone 11 according to the position of the teacher. The universal tube 10 can adjust the orientation and height of the microphone 11 at will. It is convenient for teachers to use.

Of course, the above descriptions are not limitations of the present utility model, and the present utility model is not limited to the above-mentioned examples. Changes, modifications, additions or replacements made by those of ordinary skill in the art within the essential scope of the present utility model also belong to Protection scope of the present utility model.
