Description

Technical Field

[0001] The utility model relates to the field of vision training, and more particularly to a pixel board for vision training. Background Art

[0002] The building block pixel board can be nested one by one. The building block particles are set to use two or three of the following colors: blue, green, and red. Other colors can be added to form patterns, such as floral patterns. These can then be paired with red, green, and blue glasses for vision training. Generally, if the pixel particles use red and green as the primary colors, red-green glasses are worn; if red and blue are the primary colors, red-blue glasses are worn. The red lens filters out blue light, allowing only the red building block particles to be seen, while the blue lens filters out red light. By training each eye to see only a subset of specific colors, it can help correct amblyopia.

[0003] During the use of the current pixel board, the pixel board is placed on the desktop, and the user has to keep his head down for amblyopia correction training. After long-term training, the user can clearly feel the discomfort in the neck position, and the overall user experience is poor. Utility Model Content

[0023] See also Figure 1-3 The present invention provides a technical solution: a pixel board for vision training, comprising a board frame 1 and a pixel board body 3, wherein the front of the pixel board body 3 is evenly provided with inlays 301, and building blocks 302 of different colors are movably nested on the outside of the inlays 301, and a slot 2 is provided on the front of the board frame 1 for convenient engagement with the pixel board body 3, and connecting shafts 4 are fixedly connected on both sides of the bottom of the pixel board body 3, and the connecting shafts 4 are rotatably connected to the inner wall of the slot 2, and a handle is fixedly connected to the side of the board frame 1 away from the connecting shaft 4 5. The bottom of the pixel board body 3 is evenly provided with card slots 8. The inner wall of the slot 2 is provided with a second frame 10 for placing the building block particles 302, and the second frame 10 is fixedly connected to the first frame 9 on both sides. The first frame 9 is movably provided with a card pin 11 that is engaged with the card slot 8 at the bottom of the pixel board body 3. The inner wall of the first frame 9 is rotatably connected to a rotating pin 901, and the outer side of the rotating pin 901 is fixedly connected to a rotating rod 902. The rotating rod 902 is accommodated in the first frame 9 and fixedly connected to the card pin 11.

[0024] Based on the above structure, when the device is in use, the staff carries the whole device through the handle 5, and when in use, places the board frame 1 flat on the table, then rotates the connecting shaft 4 to adjust the angle of the pixel board body 3, and synchronously rotates the rotating pin 901 to rotate the rotating rod 902 and the connected latch 11 to adjust the angle, and makes the latch 11 engage in the latch slot 8 at the bottom of the pixel board body 3, completing the angle support and fixation of the pixel board body 3 after the angle adjustment, and then the user takes out the building block particles 302 in the second frame 10 for vision correction training. During the training process, the tilted pixel board body 3 will not cause the user to have neck discomfort due to always lowering the head for vision correction, thereby improving the overall practical effect.

[0025] It should be noted that the installation position of the rotating pin 901 can be selectively set according to the angle adjustment range of the pixel panel body 3, and the installation position of the rotating pin 901 can be changed according to actual usage requirements.

[0026] Among them, the contact surface between the pixel board body 3 and the inner wall of the slot 2 is provided with a rubber pad to increase the sealing effect of the connection, and a buckle groove 303 is also provided on the front of the pixel board body 3 to facilitate inserting a finger into the buckle groove 303 to open the pixel board body 1.

[0027] Among them, the outer side of the handle 5 is movably inserted through a limit pin 6 extending into the interior of the slot 2, and the pixel board body 3 is provided with a limit slot 7 that is engaged with the limit pin 6 on one side of the limit pin 6. The outer end of the limit pin 6 is fixedly connected to a limit block 601, and the limit block 601 is connected to the outer side of the handle 5 through a spring 602. The spring 602 is sleeved on the outer side of the limit pin 6, and the spring 602 is in a contracted state in the default state. When in use, the staff can pull the limit pin 6 through the limit block 601 and simultaneously stretch the spring 602, thereby disengaging the limit pin 6 from the limit slot 7 on the outer side of the pixel board body 3, releasing the limit on the pixel board body 3. At this time, the pixel board body 3 can be rotated and adjusted in angle by the connecting shaft 4 for use, and when the pixel board body 3 is subsequently fixed, the limit pin 6 can still be engaged with the limit slot 7 under the elastic restoring force of the spring 602, so that the pixel board body 3 can be fixed in the slot 2 on the front of the board frame 1, which is convenient for carrying and use.
