Description

Technical Field

[0001] The utility model relates to the technical field, in particular to a flip racket. Background Art

[0002] In recent years, with the acceleration of the pace of society and the popularization of electronic products, people are exposed to electronic screens for longer and longer periods of time. Long-term close viewing of electronic screens can easily cause visual fatigue, which in turn leads to the occurrence of myopia. Especially among young people, the number of myopia patients is increasing year by year.

[0003] The vision training flip racket is a commonly used visual training tool, which is mainly used to improve the eye's accommodation function and convergence function. The flip racket trains the eye's accommodation ability by alternating between positive and negative lenses. The flip racket provides different visual stimuli to promote the training of the eye's accommodation muscles, improve the accommodation sensitivity and amplitude, and improve the visual quality. It has a positive effect on myopia prevention and control and visual fatigue relief.

[0004] However, when the existing flip-up racket is in use, it is usually composed of two lenses with different refractive powers, a positive lens and a negative lens, which are installed on an easily flippable device. The device is automatically flipped to alternately observe the sight mark through the positive lens and the negative lens for training. However, in this flipping method, the lenses are mostly folded and flipped at 90 degrees, and the degree is changed by the combination of two lenses. This mode structure is relatively complex, resulting in a large number of parts driving the alternation of lenses. It is impossible to use a simple structure to achieve the alternation between the lenses, thereby increasing the cost required for production. Utility Model Content

[0005] The utility model aims to solve the problem that the existing flip racket cannot realize the switching between lenses by using a simple structure when in use, thus causing the increase of production cost.

The two groups of mirror holes accommodate different lenses, namely the first lens 5 and the second lens 11. The first lens 5 is a positive lens and the second lens 11 is a negative lens. The frame 4 moves vertically following the frame 3.

[0040] The adjusting device further comprises: a movable tooth plate 10 , a spur gear 9 , a reduction box 8 and a driving motor 7 .

[0041] Specifically, the movable tooth plate 10 is composed of a rack and a movable plate. The surface of the movable plate is fixedly connected to the rack, and the top of the movable plate is fixedly connected to the mirror frame 3 by bolts, and the mirror frame 3 can be disassembled by bolts; the spur gear 9 is meshingly connected to the movable tooth plate 10, and when the spur gear 9 rotates, the movable tooth plate 10 will move vertically; the output end of the reduction gear 8 is fixedly connected to the axis of the spur gear 9, and the output end of the reduction gear 8 can drive the spur gear 9 to rotate. The reduction gear 8 is used to reduce the rotation speed of the drive motor 7. The reduction gear 8 is a prior art and will not be described in detail here; the output end of the drive motor 7 is fixedly connected to the input end of the reduction gear 8. The model of the drive motor 7 is selected according to actual needs and meets the working conditions.

[0042] The flip racket also includes: a shell 1; a processor and a contact sensor are arranged inside the shell 1, and the processor is electrically connected to the contact sensor; the processor is electrically connected to the drive motor 7, and is used to control the start and stop of the drive motor 7. The processor can generate a drive signal in response to the sensor signal sent by the contact sensor to make the drive motor 7 run.

[0043] The flip racket also includes: a contact 14; the contact 14 is arranged at the bottom end of the movable tooth plate 10, and the contact 14 can be fitted with the contact sensor to trigger the contact sensor. When the contact 14 moves to the highest position and the lowest position, the contact sensor will be triggered. Figure 4 The position shown is the lowest position of the contact 14 . When the second lens 11 replaces the first lens 5 , the contact 14 is at the highest position.

[0044] The flip racket also includes: a rotating member 6; the rotating member 6 is composed of a baffle and a rotating shaft, one end of the rotating shaft is fixedly connected to the baffle, and the other end of the rotating shaft passes through the corresponding position of the shell 1 and is rotatably connected to the shell 1. The rotating member 6 can block one of the lens hole positions for single-eye training.

[0045] A slideway is provided at the connection between the mirror frame 4 and the mirror frame 3, and the mirror frame 4 is slidably connected to the mirror frame 3 via the slideway.

[0046] In this embodiment, the mirror frames 4 may also be divided into two groups, and the distance between the two groups of mirror frames 4 can be adjusted by a slide.

[0047] The flip racket also includes: two groups of limit blocks 12; each group of limit blocks 12 is set on the frame 4, and a baffle is set in the middle of the two sides of the frame 3, and the baffle cooperates with the limit blocks 12 to limit the position of the frame 4. By pulling the frame 4 outward, the distance between the two groups of frames 4 can be adjusted to suit the distance between the eyes of different users.

[0048] The flip racket also includes: one or more groups of prism marks 13, which are rectangular plates; each group of prism marks 13 is set on the frame 4 and located at the edge of the lens hole, which is used for positioning when installing the prism. A mark is also set on the prism, and the mark on the prism is aligned with the prism mark 13 to achieve the installation of the prism.

[0049] Working principle:

[0050] When the flip racket is in use, the user first installs the first lens 5 of the positive lens and the second lens 11 of the negative lens to the lens hole position on the frame 4, and then pulls the frame 3 outward according to the distance between the user's eyes so that the lens hole is aligned with the user's eyes. The user's eyes look at the eye chart through the first lens 5 to perform strength training, and then presses the trigger button 2, and starts the drive motor 7 through the processor. The output speed of the drive motor 7 drives the spur gear 9 to rotate after being decelerated by the reduction box 8. The spur gear 9 makes the moving gear plate 10 move vertically upward, and the moving gear plate 10 drives the first lens 5 through the frame 4. The plate 5 and the second lens 11 move simultaneously, so that the second lens 11 moves to the position of the first lens 5, completing the replacement of different lenses. At the same time, moving the tooth plate 10 will drive the contact 14 to move. When the second lens 11 moves to the position of the first lens 5, the contact 14 will trigger the contact sensor, thereby stopping the drive motor 7 and accurately moving the second lens 11 to the position of the first lens 5. Pressing the trigger button 2 again can make the drive motor 7 turn over and rotate, thereby moving the first lens 5 back to its original position. After multiple lens exchanges, the user's eyes are trained and the use of this device is completed.
