Description

Technical Field

[0001] The utility model belongs to the technical field of Chinese language and literature learning, and in particular relates to a text spelling comparison display device. Background Art

[0002] Spelling is writing with phonetic letters according to phonetic rules. The spelling of Chinese characters describes the pronunciation, shape and meaning of Chinese characters, and uses it as the spelling application style of Chinese characters. The pronunciation part describes the pronunciation attributes of words. It spells words according to the provisions of the Pinyin scheme and the basic rules of Pinyin orthography. The shape and meaning feature part describes the attributes of words such as stroke order, radicals, component combination, part of speech or meaning, or the distinguishing features of homophones. The sequence number part describes the arrangement order of words in the same attribute category. It itself is also a language attribute, which makes the attribute description of words certain. This common "universal model" is open, and it can be continuously discarded and absorbed to meet the needs of social informatization.

[0003] In the prior art, a display device is required to place a copybook spelling template when spelling words, so as to perform spelling and display. However, due to its fixed use area, when a wider copybook spelling template is placed on the existing display device, both sides of the copybook fall or bend along the display device, which not only makes it impossible for the user to fully view the copybook, but also causes the user to constantly adjust the copybook spelling position to view and spell, which is time-consuming and laborious, inconvenient to use, and increases the workload of the user. Therefore, we propose a text spelling comparison display device with easy-to-use functions, which is urgently needed to be developed. Utility Model Content

Figure 3 , both sides of the inner cavity of the display table body 11 are provided with moving grooves, the inner cavity of the moving grooves is slidably connected with moving blocks, and the moving blocks are connected to the display table body 11;

[0035] When the user needs to increase the use area of ​​the display table 11, the handle can be manually twisted, the handle drives the worm 22 to rotate, the worm 22 drives the worm wheel 23 to rotate, the worm wheel 23 drives the rotating rod 24 to rotate, the rotating rod 24 drives the rotating plate 25 to rotate, the rotating plate 25 pushes the push plate 26 to move toward the outside of the display table 11, the push plate 26 drives the movable plate 27 to expand toward the outside of the display table 11, at this time, the user can place a longer spelling copybook or a copybook that has been spelled for display, and to further optimize this solution, the user can install a page clip on the surface of the movable plate 27 to clamp the completed copybook, at this time, the user clamps the two sides of the copybook with the page clip and the limit assembly 3 respectively, so as to facilitate the user to display the copybook, and then the movable plate 27 drives the limit assembly 3 to move;

[0036] The top of the display table 11 is attached with a limit assembly 3 , and the movable plate 27 is used in conjunction with the limit assembly 3 .

[0037] like Figures 2 to 8 As shown, the limiting assembly 3 includes a fixing frame 31 which is glued to the display table body 11, wherein the bottom of the fixing frame 31 is connected with a Velcro or other parts which can be glued and installed to the display table body 11, and as a further optimization of the technical solution, the user can open a threaded hole on the top of the display table body 11, and install a bolt adapted to the threaded hole on the surface of the fixing frame 31, and a limiting groove 32 is opened on the top of the fixing frame 31, and a first limiting plate 33 is slidably connected to the inner cavity of the limiting groove 32, and a first running plate 34 is rotatably connected to the top of the first limiting plate 33, and a second limiting plate 35 is connected to the top of the fixing frame 31, and a second running plate 36 is rotatably connected to the top of the second limiting plate 35, and the first running plate 34 and the second running plate 36 are rotatably connected on opposite sides;

[0038] like Figures 5 to 8As shown, the top of the fixing frame 31 is slidably connected with a plurality of guide plates 39, the bottom of the guide plate 39 is provided with a guide groove 310, the inner cavity of the guide groove 310 is slidably connected with a slide bar 37, the surface of the slide bar 37 and the bottom of the guide plate 39 are respectively connected with mounting plates 38, and the two mounting plates 38 are movably connected on opposite sides, the first running plate 34, the second running plate 36 and the surface of the mounting plate 38 are connected with the slide bar 37, and the user can set a plurality of limit assemblies 3 according to actual use, so as to limit the placement of a wider text scroll for easy use , both sides of the top of the guide plate 39 are connected to springs 311, the top of the spring 311 is connected to a pressure plate 312, one side of one of the guide plates 39 is connected to a connecting plate 313, and when the user needs to use the limit assembly 3, the user first manually sticks the fixing frame 31 on the top of the display table 11, and manually screws the connecting plate 313 to the movable plate 27, and when the limit assembly 3 is not needed, it can be manually disassembled to avoid occupying the space of the display table 11. The side of the connecting plate 313 away from the guide plate 39 is screwed to the movable plate 27;

[0039] When the user places a template for spelling, the user can manually lift the pressing plate 312 to move upward. During the process, the pressing plate 312 pulls the spring 311 to stretch. When the height is appropriate, the pressing plate 312 can be loosened and the spring 311 can be used to press down and limit the two sides of the pressed object. When a wider spelling template needs to be placed, the stretching component 2 can be started. When the stretching component 2 is stretched, the connecting plate 313 can be pulled by the moving plate 27 to move synchronously. The connecting plate 313 drives the guide plate 39 to move, and the guide plate 39 pulls the mounting plate 38 to move synchronously. During the process, the guide plate 39 pushes the slide bar through the guide groove 310 37 moves synchronously, the slide bar 37 pulls the mounting plate 38 to move, thereby driving multiple mounting plates 38 to extend, and then the mounting plate 38 drives the second running plate 36 to move, and at the same time pulls the first running plate 34 to extend synchronously, and drives the first limiting plate 33 to slide in the limiting groove 32 through the first running plate 34, so as to avoid damage during the extension process, thereby achieving the purpose of extending the guide plate 39. At this time, the user can place a wider copybook spelling template or other spelling supplies, and then the user can compare the copybook spelling template next to the limiting component 3 for easy use.

[0040] The working principle of a text spelling comparison display device is as follows: when the user needs to expand the use area of ​​the display table 11 and display the spelled text, the user can manually twist the extension component 2 to extend it to both sides of the display table 11, and then during the process, the extendable component 2 can stretch the limiting component 3, so that the user can place copybook spelling templates of different widths for easy use.

[0041] It is understood that the present invention is described by some embodiments, and those skilled in the art are aware that various changes or equivalent substitutions may be made to these features and embodiments without departing from the spirit and scope of the present invention.
