Description

Technical Field

[0001] The utility model relates to the field of Chinese language teaching, in particular to a Chinese character teaching aid device. Background Art

[0002] Chinese characters are the foundation of learning the Chinese language. The form and structure of Chinese characters can be divided into four levels: Chinese character, component, stroke, and stroke form. According to the number of components in a Chinese character, Chinese characters can be divided into single-component characters and multi-component characters. Radicals are the character-forming components of multi-component characters. Based on the positional relationship between components, Chinese character structures can be classified into left-right structure, top-bottom structure, left-middle-right structure, top-middle-bottom structure, etc. Some Chinese characters have extremely similar constituent components or share one identical constituent component. To facilitate students to master such Chinese characters proficiently, similar-shaped characters are often taught together during the teaching process to improve teaching quality.

[0003] Chinese Patent No. ZL201420450917.7 discloses a Chinese language teaching device, which combines to form Chinese characters with similar structures through the rotational combination of different cards, realizing the teaching operation of similar Chinese characters; however, its card combination structure can only realize the left-right combination of characters and radicals, and cannot realize the overlapping combination of characters, radicals and strokes, which leads to the situation that many similar Chinese characters cannot be taught in a unified manner; for example, it can realize the combination of "日" and "月" to form "明", but cannot add one stroke to "日" to turn it into Chinese characters such as "白", "申", and "电".

[0004] On the other hand, limited by the volume of the device, the device can only be demonstrated in front of a small number of people. During the teaching operation, students at the back of the classroom cannot see the changes in the Chinese character combination at all, which is not conducive to the progress of teaching work, so it is necessary to improve it. Summary of the Invention

[0005] The purpose of the utility model is to address the above problems and provide a Chinese character teaching aid device with simple structure and convenient use.

[0006] To achieve the above objectives, the technical solution of the utility model is as follows: A Chinese character teaching aid includes a font assembly mechanism.

[0010] Furthermore, the limiting assembly includes a limiting rod, a top seat, and a spring. The top end of the limiting rod is connected to the top seat, and the spring is located between the top seat and the outer wall of the positioning ring. The spring is sleeved on the outside of the limiting rod, with the top end of the spring connected to the top seat and the bottom end of the spring connected to the outer wall of the positioning ring. Under the elastic action of the spring, the bottom end of the limiting rod passes through the positioning through hole and extends into the positioning blind hole.

[0011] Furthermore, the light-gathering mechanism includes a light-gathering housing and a light source. The light-gathering housing is a hollow housing structure with an opening on one side. The opening end of the light-gathering housing is correspondingly provided with a light-gathering clearance opening on the shielding plate. A hinge is fixedly connected to the outer wall of the bottom end of the light-gathering clearance opening on the shielding plate and is rotatably connected to the bottom wall of the opening end of the light-gathering housing through the hinge. A first buckle is provided on both outer walls of the light-gathering clearance opening on the shielding plate and is engaged with a second buckle provided on both side walls of the opening end of the light-gathering housing. A light source is provided on the side of the light-gathering housing away from the opening end. The light emitted by the light source passes through the light-gathering clearance opening, then passes through the rotating disk and the transparent writing board in sequence, and is projected onto the projection screen.

[0012] Furthermore, an adjustment assembly is provided on the side of the light-inlet housing away from the opening end, and is connected to the light source component through the adjustment assembly; the adjustment assembly includes a fixed sleeve and a movable sleeve. A light-inlet mounting port is provided at the center of the side of the light-inlet housing away from the opening end. A fixed sleeve is fixedly connected inside the light-inlet mounting port. The fixed sleeve is open at both ends along its axial direction, and the axial direction of the fixed sleeve is parallel to the axial direction of the rotating disk.

[0014] Furthermore, a placement frame is provided at the bottom of the fixed base, and the top of the placement frame is fixedly connected to the outer wall of the bottom end of the positioning ring.

[0015] Compared with the prior art, the advantages and positive effects of this utility model are: In use, this invention involves first rotating the rotating disk so that the writing clearance opening aligns with the light inlet clearance opening and the transparent writing board. A fixed character is then written on the transparent writing board using a black pen. Next, the rotating disk is rotated again. When the blank area of ​​the rotating disk reaches the outside of the fixed character, strokes or radicals are written on the outer wall of the rotating disk using a black pen. These strokes or radicals overlap and combine with the fixed character to form similar Chinese characters. After writing multiple strokes or radicals, the light inlet mechanism is moved to the position of the light inlet clearance opening. The light emitted by the light source in the light inlet mechanism passes through the light inlet clearance opening, then through the rotating disk and the transparent writing board, and is projected onto the projection screen. The projection screen displays the overlapped and combined Chinese characters. As the rotating disk rotates, different strokes or radicals combine with the fixed character to form different similar Chinese characters, achieving a unified teaching and explanation effect for multiple similar Chinese characters. This invention allows for both left-right combinations of characters, radicals, and strokes, as well as overlapping combinations, expanding the range of similar Chinese characters that can be combined and preventing situations where many similar characters cannot be taught uniformly. Furthermore, by projecting the light onto fixed characters, strokes, and radicals using a light-gathering component, the combined similar characters can be magnified and displayed on a projection screen, facilitating viewing for students at the back of the classroom and ensuring stable teaching. Simultaneously, the projection operation ensures clear display of overlapping characters on the projection screen, avoiding interference from rotating discs, overlapping areas on transparent writing boards, and unclear characters in overlapping areas, which are present when visually viewing overlapping characters, further improving the effectiveness of this invention.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, any modifications, equivalent substitutions, improvements, etc., made by those skilled in the art to all other embodiments obtained without creative effort should be included within the protection scope of the present utility model.

[0019] like Figures 1 to 9 As shown, this embodiment discloses a Chinese character teaching aid device, including a font combination mechanism 4, and a light-gathering mechanism 4 is provided on one side of the font combination mechanism, and the light-gathering mechanism 4 is movably connected to the font combination mechanism; The font assembly mechanism includes a fixed base 1 and a rotating disk 3. A placement frame 2 is fixedly connected to the bottom end of the fixed base 1, and the fixed base 1 and the rotating disk 3 are rotatably connected. The fixed base 1 is integrally formed from a support plate 11, a positioning ring 12, and a shielding plate 13. The support plate 11 and the shielding plate 13 are both circular plates and are arranged parallel to each other. The positioning ring 12 is circular and is disposed between the support plate 11 and the shielding plate 13. One axial side of the positioning ring 12 is connected to the circumferential edge of the support plate 11, and the other axial side of the positioning ring 12 is connected to the circumferential edge of the shielding plate 13. The rotating disk 3 is a transparent circular plate and is sleeved on the positioning ring 1. 2. On the inner side, the rotating disk 3 is disposed between the support plate 11 and the shielding plate 13. The rotating disk 3 and the support plate 11 are coaxially disposed. The center of the rotating disk 3 is provided with a pin hole 34 and is connected to the mounting shaft 112 disposed at the center of the support plate 11 through the pin hole 34. The rotating disk 3 is provided with a writing clearance opening 33 at an eccentric position. The support plate 11 is provided with a mounting opening corresponding to the writing clearance opening 33. A transparent writing board 111 is fixedly connected in the mounting opening. The shielding plate 13 is provided with a light-entry clearance opening 131 corresponding to the mounting opening. A light-entry mechanism 4 is provided on the outside of the light-entry clearance opening 131 and is movably connected to the shielding plate 13.

[0020] The center of the baffle plate 13 is provided with a handle clearance opening 132, and a handle 31 is provided on the side of the rotating disk 3 near the baffle plate 13. The handle 31 is located at an off-center position on the outer wall of the rotating disk 3. One end of the handle 31 is fixedly connected to the outer wall of the rotating disk 3, and the other end of the handle 31 extends out from the handle clearance opening 132. The rotating disk 3 can be easily rotated through the handle 31.

[0021] A plurality of positioning blind holes 32 are arranged at equal intervals along the circumferential direction of the rotating disk 3 on the outer peripheral side wall of the rotating disk 3, and the positioning ring 12 is provided with a positioning through hole 121; when the writing avoidance opening 33 corresponds to the mounting opening, the positioning through hole 121 corresponds to one of the positioning blind holes 32; a limit assembly 5 is arranged in the positioning through hole 121, and the rotation state of the rotating disk 3 is controlled by the limit assembly 5.

[0022] Through the matching design of the limit assembly and the plurality of positioning blind holes, the rotating disk is provided with one avoidance area and a plurality of writing areas, that is, the writing avoidance opening on the rotating disk serves as the avoidance area. When the writing avoidance opening corresponds to the transparent writing board, the limit assembly fixes one positioning blind hole on the rotating disk, which facilitates the font writing operation on the transparent writing board; when the limit assembly fixes the rotating disk through other positioning blind holes, the position on the rotating disk corresponding to the transparent writing board is the writing area, and after positioning, it is convenient to write strokes or radicals in the writing area; at the same time, by positioning the avoidance area and the writing area, it is convenient to realize the precise matching of overlapping fonts in subsequent teaching, avoid the situation of misalignment of strokes and radicals of overlapping fonts, and further improve the use effect of the present utility model.

[0023] as Figure 7 shown, the character "ri" can be written on the transparent writing board through the writing avoidance opening on the rotating disk; strokes such as "丨" and "丿" are written on the writing area on the rotating disk. As the rotating disk continuously rotates, the strokes on the rotating disk will sequentially overlap with the character "ri" to form characters such as "shen", "bai", "jia", "you" and "dian" (as Figure 8 , Figure 9 shown), thereby realizing the teaching effect of combination and display of overlapping fonts.

[0024] The limit assembly 5 includes a limit rod 51, a top seat 52 and a spring 53. The top end of the limit rod 51 is connected to the top seat 52. The spring 53 is located between the top seat 52 and the outer side wall of the positioning ring 12. The spring 53 is sleeved on the outer side of the limit rod 51. The top end of the spring 53 is connected to the top seat 52, and the bottom end of the spring 53 is connected to the outer side wall of the positioning ring 12. Under the elastic force of the spring 53, the bottom end of the limit rod 51 passes through the positioning through hole 121 and then extends into the positioning blind hole 32.

[0025] By pulling the top seat upward, the bottom end of the limit rod can be separated from the positioning blind hole. At this time, the rotating disk can be rotated. When rotated to the position of the next positioning blind hole, the top seat is released, and the limit rod can be inserted into the positioning blind hole under the action of the spring, so as to realize the positioning operation of the rotating disk.

[0026] The light-gathering mechanism 4 includes a light-gathering housing 41 and a light source 45. The light-gathering housing 41 is a hollow housing structure with an opening on one side. The opening end of the light-gathering housing 41 is correspondingly set with the light-gathering clearance opening 131 on the baffle plate 13. A hinge 42 is fixedly connected to the outer wall of the bottom end of the light-gathering clearance opening 131 on the baffle plate 13, and the hinge 42 is rotatably connected to the bottom wall of the opening end of the light-gathering housing 41. The outer walls of both sides of the light-gathering clearance opening 131 on the baffle plate 13 are provided with a first buckle 133, and the first buckle 133 is engaged with the second buckle provided on the side walls of both sides of the opening end of the light-gathering housing 41. The light source 45 is set on the side of the light-gathering housing 41 away from the opening end. The light emitted by the light source 45 passes through the light-gathering clearance opening 131, passes through the rotating disk 3 and the transparent writing board 111 in sequence, and is projected onto the projection screen installed on the classroom wall.

[0027] When writing is required on the transparent writing board and the rotating disk, open the latches on both sides of the light-inlet housing, flip the light-inlet housing downwards to expose the light-inlet obstruction opening on the shielding plate, and then write. After writing, flip the light-inlet housing upwards to connect the two sides of the light-inlet housing with the shielding plate latches, allowing the light from the light source to shine through the light-inlet obstruction opening onto the writing area and the projection screen, achieving the projection display effect of overlapping characters. Furthermore, the shielding plate design prevents students from seeing the radicals and strokes behind the overlapping characters on the rotating disk, facilitating the sequential conduct of teaching. It also prevents the light emitted by the light source from spreading, improving the projection effect of overlapping characters.

[0028] An adjustment assembly is provided on the side of the light-inlet housing 41 away from the opening end, and is connected to the light source component through the adjustment assembly. The adjustment assembly includes a fixed sleeve 43 and a movable sleeve 44. A light-inlet mounting port is provided at the center of the side of the light-inlet housing 41 away from the opening end. The fixed sleeve 43 is fixedly connected inside the light-inlet mounting port. The fixed sleeve 43 is open at both ends in the axial direction, and the axial direction of the fixed sleeve 43 is parallel to the axial direction of the rotating disk 3. The movable sleeve 44 is open at one end in the axial direction and the open end faces the rotating disk 3. The movable sleeve 44 is sleeved inside the fixed sleeve 43 and the outer wall of the movable sleeve 44 is threaded to the inner wall of the fixed sleeve 43. A light-emitting light source component 45 is fixedly connected inside the movable sleeve 44.

[0029] The distance between the light source and the rotating disk can be adjusted by rotating the movable sleeve, thereby adjusting the size of the projection area. This makes it convenient to project overlapping text onto the projection screen at an appropriate size during teaching, thus improving the ease of operation of this invention.

[0030] In use, this invention involves first rotating the rotating disk so that the writing clearance opening aligns with the light inlet clearance opening and the transparent writing board. A fixed character is then written on the transparent writing board using a black pen. Next, the rotating disk is rotated again. When the blank area of ​​the rotating disk reaches the outside of the fixed character, strokes or radicals are written on the outer wall of the rotating disk using a black pen. These strokes or radicals overlap and combine with the fixed character to form similar Chinese characters. After writing multiple strokes or radicals, the light inlet mechanism is moved to the position of the light inlet clearance opening. The light emitted by the light source in the light inlet mechanism passes through the light inlet clearance opening, then through the rotating disk and the transparent writing board, and is projected onto the projection screen. The projection screen displays the overlapped and combined Chinese characters. As the rotating disk rotates, different strokes or radicals combine with the fixed character to form different similar Chinese characters, achieving a unified teaching and explanation effect for multiple similar Chinese characters. This invention allows for both left-right combinations of characters, radicals, and strokes, as well as overlapping combinations, expanding the range of similar Chinese characters that can be combined and preventing situations where many similar characters cannot be taught uniformly. Furthermore, by projecting the light onto fixed characters, strokes, and radicals using a light-gathering component, the combined similar characters can be magnified and displayed on a projection screen, facilitating viewing for students at the back of the classroom and ensuring stable teaching. Simultaneously, the projection operation ensures clear display of overlapping characters on the projection screen, avoiding interference from rotating discs, overlapping areas on transparent writing boards, and unclear characters in overlapping areas, which are present when visually viewing overlapping characters, further improving the effectiveness of this invention.
