Description

Technical Field

[0001] This invention relates to the field of foreign language oral practice, specifically to an interactive teaching aid for foreign language oral practice. Background Technology

[0002] Because English is a language subject, there are very few teaching aids available, especially when English teachers are writing on the blackboard. Often, the four-line grid they draw is not level, resulting in messy and illegible English letters, which affects the quality of teaching. Therefore, a tool that can quickly draw the four-line grid on the blackboard is essential. Summary of the Invention

[0003] The purpose of this invention is to provide an interactive teaching aid for foreign language oral practice, so as to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, the present invention provides the following technical solution: an interactive teaching aid for foreign language oral practice, comprising a front support, a rear support, screws, screw sleeves, a fixing rod, and chalk sleeves. The bottom end of the front support is connected to a front wheel, and the top end of the front support is connected to the top end of the rear support via a hinge. The bottom end of the rear support is connected to the rear wheel. The front support and the rear support are respectively connected to two screws via hinges, and the two screws are connected via screw sleeves. A fixing rod is placed on the outside of the rear support, and four chalk sleeves are fixedly installed on the outside of the fixing rod. The chalk sleeves have a hollow structure, and the top of the chalk sleeves is connected to a spring cap via threads.

[0005] Preferably, a rotary wrench is fixedly mounted on the screw sleeve housing.

[0006] Preferably, the four chalk tip sleeves are spaced equally apart and arranged in the same direction as the rear support.

[0007] Preferably, the internal cavity size of the chalk sleeve is adapted to the size of the chalk.

[0008] Preferably, a spring is fixedly placed at the center of the inside of the spring cover.

[0009] The beneficial effects of this invention are: by replacing the action of drawing lines by hand with the linear rolling of the cart, and with four chalk sleeves fixedly installed at the back of the cart, it is convenient to draw quarter lines directly while the cart is rolling, which not only saves the time of drawing lines by hand and classroom teaching time, but also improves the teaching quality. Attached Figure Description

[0010] Figure 1 This is a schematic diagram of the present invention; In the picture: 1 front bracket, 2 front wheel, 3 rear bracket, 4 rear wheel, 5 screw, 6 screw sleeve, 7 fixing rod, 8 chalk shell, 9 spring cover. Detailed Implementation

[0011] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0012] This invention provides, for example Figure 1 The illustrated interactive teaching aid for foreign language oral practice includes a front support 1, a rear support 3, screws 5, screw sleeves 6, a fixing rod 7, and chalk sleeves 8. The bottom of the front support 1 is connected to a front wheel 2, and the top of the front support 1 is connected to the top of the rear support 3 via a hinge. The bottom of the rear support 3 is connected to a rear wheel 4. The front support 1 and the rear support 3 are each connected to two screws 5 via hinges, and the two screws 5 are connected by screw sleeves 6. A fixing rod 7 is placed on the outside of the rear support 3, and four chalk sleeves 8 are fixedly installed on the outside of the fixing rod 7. The chalk sleeves 8 have a hollow structure, and the top of the chalk sleeves 8 is connected to a spring cap 9 via threads.

[0013] Furthermore, a rotary wrench is fixedly mounted on the outer shell of the screw sleeve 6.

[0014] Furthermore, the four chalk tip sleeves 8 are spaced equally apart and arranged in the same direction as the rear support 3.

[0015] Furthermore, the internal cavity size of the chalk sleeve 8 is adapted to the size of the chalk.

[0016] Furthermore, a spring is fixedly installed at the center of the inside of the spring cover 9.

[0017] When using the chalk, simply adjust the screw sleeve 6 according to the chalk's hardness to ensure the angle between the front bracket 1 and the rear bracket 3 is appropriate, preventing the chalk from breaking during use. Then, insert the chalk into the chalk sleeve 8 and manually push the cart to draw quarter lines on the blackboard for English writing. Simultaneously, the spring cover 9 continuously pushes the chalk outwards during use to meet the needs of line drawing. This eliminates the cumbersome process of drawing lines with a ruler and chalk in the past.

[0018] Finally, it should be noted that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
