Description

Rotary wheel English teaching teaching device

technical field

The utility model relates to the technical field of English teaching appliances.

Background technique

At present, students need to master or memorize a large number of English words to improve their vocabulary. The general method is to recite or memorize these words by combining handwriting, oral reading and memorization. In the process of English teaching, it is often necessary to use teaching Cards and teaching cards are generally hard papers printed in advance, so it is not convenient to demonstrate when combining English words, which increases the difficulty of English teaching. The existing teaching device is slow to replace the teaching content, and cannot combine multiple English cards, especially for the explanation and memory of English words, which cannot meet the needs of fast teaching, and the existing English word memory is generally the teacher’s Explaining on the blackboard is boring and reduces students' interest in learning, thus reducing the quality of teaching.

Contents of the invention

The technical problem to be solved by the utility model is to provide a wheel-type English teaching and teaching device for the above-mentioned technical deficiencies, which can integrate a plurality of teaching cards, which saves space, is simple to operate, and is convenient for demonstration.

The technical solution adopted by the utility model is: provide a wheel-type English teaching and teaching device, including a disc-shaped panel, a panel cover that matches the shape of the panel and is connected by a rotating shaft, and a leg installed at the bottom of the panel; There is a rectangular observation hole on the front side in the horizontal and diameter direction; a lens window is installed on the observation hole; the magnification direction of the lens window is perpendicular to the length direction of the observation hole; a teaching card is connected between the panel and the panel cover through the rotating shaft , the outer edge of the teaching card extends to the outside of the panel; the front surface of the teaching card is evenly distributed with teaching words in the circumferential direction; the compression ratio of the teaching words along the width direction of the lens window matches the enlargement ratio of the lens window.

To further optimize this technical solution, the rotating shaft of the wheel-type English teaching and teaching device is made of transparent material, and a light-emitting diode is installed in the rotating shaft.

To further optimize this technical scheme, the front side of the panel cover of the wheel-type English teaching and teaching device has a rectangular observation hole horizontally and in the diameter direction; a lens window is installed on the observation hole; The length direction is vertical.

To further optimize this technical solution, the legs of the wheel-type English teaching and teaching device are divided into two sections of sleeves that are socketed and positioned by friction in the length direction.

The beneficial effects of the utility model are: 1. Utilize the lens window to amplify the compressed teaching words, reduce the space occupied by the teaching words as a whole, integrate more learning content, just rotate the teaching card during operation, save time.

2. The teaching content can be set on both sides of the teaching card, and the teaching demonstration can also be carried out from the side of the panel cover, which further improves the teaching efficiency and reduces the labor intensity of the teacher.

Detailed ways

Below in conjunction with accompanying drawing and specific embodiment, the utility model is described in further detail.

As shown in Figures 1 and 2, the wheel-type English teaching and teaching device includes a disc-shaped panel 1, a panel cover 2 that is matched with the panel 1 and connected through a rotating shaft 6, and a leg 3 installed at the bottom of the panel 1; The front side of 1 has a rectangular observation hole 4 horizontally and in the diameter direction; a lens window 5 is installed on the observation hole 4; the magnification direction of the lens window 5 is perpendicular to the length direction of the observation hole 4; The teaching card 7 is rotated and connected with the rotating shaft 6, and the outer edge of the teaching card 7 extends to the outside of the panel 1; the front surface of the teaching card 7 is evenly distributed with teaching words 8 in the circumferential direction; the teaching words 8 are arranged along the lens The compression ratio in the width direction of the window 5 matches the enlargement ratio of the lens window 5; the rotating shaft 6 is made of transparent material, and a light-emitting diode 9 is installed in the rotating shaft 6; the front side of the panel cover 2 has a rectangular observation hole horizontally and in the diameter direction 4; a lens window 5 is installed on the observation hole 4; the magnification direction of the lens window 5 is perpendicular to the length direction of the observation hole 4; the legs 3 are divided into two sections of sleeves 10 that are socketed and positioned by friction in the length direction.

The lens window 5 is arranged along the direction of the observation hole 4, and it is a convex lens with a fixed direction in essence. The direction of enlargement is only perpendicular to the length direction of the observation hole 4, and the compression integration of the teaching words 8 is mainly reflected in the circumferential direction. In the radial direction of the panel 1, the teaching words 8 are not compressed, and the lens window 5 has no enlarging effect on this direction. During the demonstration, under the magnification of the lens window 5, the teaching word 8 presents a state of normal proportion.

In addition, the abbreviation 11 of the teaching word 8 is printed on the outer edge of the teaching card 7, so that the position of the corresponding teaching word 8 can be easily corresponded to.

The light emitting diode 9 can improve the brightness between the panel 1 and the panel cover 2, which is beneficial for students to see the teaching content more clearly and brightly.
