Description

Technical Field

[0001] This utility model relates to the field of demonstration device technology, specifically a novel demonstration device for teaching. Background Technology

[0002] Chinese, the traditional language of the Han Chinese, is the common language of China and one of the international languages. It is mainly spoken in China and Southeast Asian countries such as Singapore, Malaysia, Myanmar, and Thailand, as well as in Chinese communities in countries such as the United States, Canada, Australia, New Zealand, and Japan. The new type of demonstrator used for Chinese language teaching is a specially designed teaching aid that aims to improve the efficiency and interactivity of Chinese language teaching through a combination of various functions and structures.

[0003] However, existing new demonstrators used for teaching have the following drawbacks:

[0004] (1) Existing new demonstration devices for teaching have weak space-saving functions. Traditional demonstration devices have a fixed writing area and occupy a large space, making them difficult to fold and store, resulting in limitations of the device and reduced space utilization efficiency.

[0005] (2) Existing new demonstration devices used for teaching have weak functions in improving teaching efficiency. Because the traditional demonstration device teaching process is monotonous, it is difficult to stimulate students' learning interest, resulting in reduced device efficiency and decreased teaching quality. Utility Model Content

[0006] The purpose of this invention is to provide a novel demonstrator for teaching, in order to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a novel demonstrator for teaching, comprising: a demonstration board, an extension component, and a spelling component. A limiting slider is fixedly connected to the inner side wall of the demonstration board, and an extension board is slidably connected to the outer surface of the limiting slider. A limiting groove is formed on the side of the extension board, a handle is fixedly connected to one side of the extension board, and a placement slot is formed at the bottom of one side of the extension board. A cover plate is rotatably connected to the top of the placement slot.

[0008] A slide rail is fixedly connected to one side of the demonstration board. An adjustment groove is provided at the top of the slide rail. An adjustment slider is slidably connected inside the adjustment groove. A spelling card is fixedly connected to the top of the adjustment slider. A magnetic block is fixedly connected to one side of the spelling card. A retrieval groove is provided on the side of the spelling card. A retaining ring is fixedly connected to the bottom of the demonstration board. A connecting ring is provided on the inner side wall of the retaining ring. A storage box is fixedly connected to the bottom of the connecting ring. A partition is slidably connected to the inner side wall of the storage box.

[0009] Optionally, a support rod is fixedly connected to the bottom of the demonstration board, a base plate is fixedly connected to the bottom of the support rod, and a caster wheel is fixedly connected to the bottom of the base plate. The support rod supports and fixes the demonstration board, and the base plate connects the support rod and the caster wheel. The rotation of the caster wheel drives the device to move.

[0010] Optionally, the number of support rods is four, and the number of casters is four. The arrangement of four support rods and four casters can improve the stability of the device's movement.

[0011] Optionally, the number of slide rails is three, and the spacing between the three slide rails is the same. The spelling cards placed on the top slide rail contain tones, the spelling cards placed on the middle slide rail contain pinyin, and the spelling cards placed on the bottom slide rail contain Chinese characters.

[0012] Optionally, the demonstration board is made of iron blackboard, and the extension board is made of metallic paint. Metallic paint is sturdy and durable, has a smooth surface, is easy to write on and erase, and is magnetic, making it suitable for use with magnetic accessories.

[0013] The number of the optional retaining rings is two, and the number of the connecting rings is two. The arrangement of two retaining rings and two connecting rings can improve the stability of the storage box.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. This novel demonstration device for teaching, through the setting of the extension component, allows the extended plate to slide when held by the handle, while the limiting slider slides inside the limiting groove and limits the sliding position of the extended plate. After being pulled to a certain position, the limiting slider stabilizes the position of the extended plate. The cover is opened to take out the writing pen placed in the slot and write on the surface of the extended plate. Sliding the extended plate in the opposite direction can overlap the extended plate with the device, reducing the space occupied and achieving the effect of improving the flexibility of the device. This avoids the situation of traditional demonstration devices with fixed writing area and large space occupation, which are difficult to fold and store, resulting in the limitation of the device and reduced space utilization efficiency.

[0016] 2. This novel teaching demonstrator, through its spelling component, allows users to slide spelling cards to the top of the slide rail while simultaneously adjusting the slider within the adjustment groove. Once the spelling card is in the desired position, a magnetic block adheres to one side of the demonstration board, stabilizing the card's position. A retrieval groove facilitates easy card removal. Inserting the connecting ring into the retaining ring stabilizes the storage box, which stores the spelling cards. The divider allows for adjustment of the internal space within the storage box, enhancing the device's practicality and avoiding the limitations of traditional demonstrators that are monotonous in their teaching process, failing to stimulate student interest, and resulting in reduced device efficiency and lower teaching quality.
