The purpose of this utility model is achieved in the following way: an English learning teaching aid, the key of which is to include a blackboard body and a card inserting device arranged on the top of the blackboard body for inserting English cards. ”-shaped card frame, light tube, electromagnet and magnetic English card slot, the light tube is fixedly installed on the vertical inner wall of the card frame, and the magnetic English card slot is symmetrically arranged on the plug On the upper wall and the lower wall inside the card frame, the magnetic English card slot is arranged parallel to the inner wall of the card insertion frame, and the electromagnet is located at the end of the magnetic English card slot.

With the above-mentioned structure, English cards can be inserted into the English card inserting device, which is convenient for students to learn English words and sentences intuitively, and the English words or sentences on the cards can be further explained and learned on the blackboard body, so as to improve English High learning efficiency, by controlling the positive and negative poles of the electromagnet, the automatic receipt and ejection of cards can be realized.

The above-mentioned blackboard body is provided with a placement groove, and the top and bottom of the placement groove are provided with horizontal rotating shafts, one of which is connected to the output shaft of the motor, the two rotating shafts are arranged in parallel, and a rolling shaft is set between the two rotating shafts. As for the writing tape, the lower part of the placement groove is fixed with a brush, the outer side of the brush is close to the rolling writing tape, and the bottom of the placement groove is provided with a chalk dust leakage hole.

With the above structure, the writing tape can be written with chalk, and the motor can control the rotation of the writing tape to continuously expose the clean writing tape for writing. At the same time, the internal brush can effectively clean the chalk dust on the writing tape. The chalk dust leaks through the chalk dust leakage hole, automatically cleaning the blackboard.

The bottom of the above-mentioned blackboard body is provided with a detachable chalk dust collection box, and the dust inlet of the collection box is arranged directly opposite to the chalk dust leakage hole.

By adopting the structure, the chalk dust can be collected to prevent the dust from polluting the environment and affecting the teaching efficiency.

There is a dust outlet on the front of the above-mentioned chalk dust collection box, and a door panel is arranged at the dust outlet, and one side of the door panel is hinged with the lower or upper edge of the dust outlet. By adopting the structure, it is convenient to clean up the chalk dust.

A backing plate is provided between the two rotating shafts, the two ends of the backing plate are respectively fixedly connected to the left and right side walls of the placement groove, and one side of the backing plate is outwardly parallel to the rolling writing tape. With the above-mentioned structure, the rolling writing tape is relatively soft, and the backing plate can provide supporting force, which facilitates stable writing with chalk.

Beneficial effect:

The utility model relates to an English learning teaching aid, which is effectively combined with a blackboard, has high teaching efficiency, high automation and is convenient to use.
