Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of visual training applications, in particular to a visual training flip card with high stability. Background Technique
[0002] Flip card training exercises the eye muscles by constantly switching the line of sight focus, which helps to improve the eye's adjustment ability, control ability, reaction speed and accuracy. This method is particularly suitable for myopic patients. Although it cannot relieve myopia itself, it can enhance the eye's adjustment ability. In the treatment of amblyopia, flip card training also plays an important role. For some amblyopic children with poor adjustment function, the effect of traditional occlusion and visual stimulation training is limited, while the combination of flip card training can significantly improve vision. This is because amblyopia is not only accompanied by reduced vision, but also multiple visual function deficiencies, such as increased sensitivity to crowding phenomenon and unstable fixation ability, and flip card training is one of the effective methods for these problems.
[0003] In the process of using the existing flip card, its base material is generally traditional plastic material. During long-term hand-held use, external bacteria will adhere to the surface of the flip card, resulting in cross-infection of bacteria, and it cannot ensure the cleanliness of the flip card during the training process of children. Moreover, during the continuous adjustment of the flip card, stable positioning and fixation cannot be achieved, reducing the stability during use. Therefore, the utility model proposes a visual training flip card with high stability. Summary of the Utility Model
[0004] The technical problem to be solved by the utility model is to provide a visual training flip card with high stability.

A scale mark 102 is arranged on the front wall of the benchmark 100. The end face of the benchmark 100 is screwed with a fixed lens ring 200. The fixed lens ring 200 includes a fixed sleeve 201. LOGO sticker grooves 202 are symmetrically arranged on the front and rear walls of the fixed sleeve 201. When using the whole device, the relevant information of the product can be known through the LOGO logo inside the LOGO sticker grooves 202. The fixed sleeve 201 is sleeved on the end face of the benchmark 100 through a sleeve groove 203 opened inside, and at the same time, the fixed sleeve 201 is fixed on the end face of the benchmark 100 by screws, and the screw end cap sinks into the inside of a sinking groove 204 opened on the end face of the fixed sleeve 201. First lenses 205 are symmetrically and fixedly connected to the side wall of the fixed sleeve 201. The fixed sleeve 201 is sleeved on the end face of the benchmark 100 through the sleeve groove 203 and locked and fixed with screws to prevent falling off.
[0028] As shown in Figure 1 and Figure 4 As shown in the figure, an adjusting lens ring 300 is slidably connected to the outer wall of the benchmark 100. The adjusting lens ring 300 includes a sliding sleeve 301. A push block 302 with a triangular cross-section is fixedly connected to the front wall of the sliding sleeve 301. A plurality of arc-shaped anti-slip convex blocks 304 are symmetrically and fixedly connected to the two inclined surfaces of the push block 302, and the two groups of anti-slip convex blocks 304 are evenly distributed. When the sliding sleeve 301 is pushed, the anti-slip effect can be realized by using the plurality of anti-slip convex blocks 304 to prevent hand slipping during the pushing process. The sliding sleeve 301 is slidably connected to the outer wall of the benchmark 100 through a through groove 303 opened inside. Card slots 305 are symmetrically arranged in the middle of the side wall of the rear part of the sliding sleeve 301.
