[0027] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0028] The incidence rate of myopia in my country is getting higher and higher, and the age of onset of myopia is getting lower and lower. With the increase of age and the duration of bad eye habits, the proportion of myopia patients among college students is higher, and the proportion of high myopia has also increased significantly. It is difficult for students to maintain correct posture and eye habits during the learning process. Once bad eye habits are formed, it is very likely to lead to the occurrence of myopia.

[0029] Please refer to Figure 1-Figure 4In order to correct students' bad sitting posture during learning and develop good eye habits, the present embodiment adopts a half-reflective half-mirror plus a concave mirror to ensure that users can clearly see the words on the book and maintain a good sitting posture. By adjusting the lifting height, it can match the sitting posture size requirements of students from elementary school to high school, and the imaging distance can be further away or closer to a certain extent, thereby relaxing the tension of the ciliary muscles of the eyes and preventing myopia. It is foldable and easy to carry. The present embodiment provides a foldable eye protection zoom instrument. The size of the fixed table 1 can place an opened 16-page book. An adjustment component 2 for adjusting the height is installed on the fixed table 1. A function control component 3 for controlling the eye protection function adjustment by buttons is also installed on the fixed table 1. An imaging component 4 for correcting the sitting posture is installed on the adjustment component 2; the imaging component 4 includes an imaging support frame 401, and a rotating connection on the imaging support frame 401 There is a lens cover 402, which can be folded up when not in use for easy carrying. A lens groove is provided on the lens cover 402, in which a half-reflective half-mirror 403 for generating a first mirror image 405 is arranged, and a reflector 404 for generating a second mirror image 406 according to the first mirror image 405 is installed in the imaging support frame 401. The distance between the top of the half-reflective half-mirror 403 and the reflector 404 is greater than 50mm, and the height of the bottom of the half-reflective half-mirror 403 from the top is 260mm. The half-reflective half-mirror 403 and the reflector 404 need to make the content of the book on the fixed table 1 visible as a whole, so the size of the half-reflective half-mirror 403 and the reflector 404 is 368*260mm, and the height of the bottom of the half-reflective half-mirror 403 from the top is set to 260mm, so that the content of the book on the fixed table 1 can be completely imaged, and the reflector 404 is a concave mirror. The imaging magnification of the second mirror image 406 is 1.2, such as Figure 3 and Figure 4 As shown, the half-reflective half-mirror 403 generates a first mirror image 405, which is then imaged by the reflector 404 to generate a second mirror image 406. The image size can be magnified by 1.2 times by utilizing the concave mirror characteristics of the reflector 404, and the distance of the image can be about 3m (i.e., within the range of 2m-4m, relative to Figure 3 The center of the second mirror image 406 is 390 mm to 550 mm from the fixed table top 1. As the height of the product users covers a wide range, the visual position varies within the range of 390 mm to 550 mm from the table top height. The center of the second mirror image 406 is also the center of the imaging.

[0030] The imaging assembly 4 also includes an upper cover plate 407, a left page turning plate 408, and a right page turning plate 409 which are rotatably connected to the imaging support frame 401. The left page turning plate 408, the right page turning plate 409, and the bottom inner sides of the lens cover plate 402 are all provided with lighting lamps. By providing the lighting lamps, the contents of the book placed on the fixed table 1 can be clearly imaged. The lens cover plate 402 is provided with left and right push plates and lock tongues. The left and right push plates push the lock tongues into the left page turning plate 408 and the right page turning plate 409 respectively to fix the lens cover plate 402. The bottom of the imaging support frame 401 is rotatably connected with a baffle plate 410, and the height of the baffle plate 410 is greater than 200 mm. The upper cover plate 407 is respectively connected to the left page turning plate 408 and the right page turning plate 409 through buckles. The lens cover plate 402 is respectively connected to the left page turning plate 408 and the right page turning plate 409 through buckles. The right page turning plate 409 is connected by a locking tongue, and the book is spread out and placed on the fixed table 1. In order to reserve space for turning the pages of the book, the space separated by the baffle 410 can ensure the normal turning of the pages of the book and prevent the imaging component 4 from falling too low and affecting the turning of the pages. When it is not needed, the baffle 410 can be flipped toward the fixed table 1, and the upper cover 407 can be flipped upward to release the buckles locked on the left page turning plate 408 and the right page turning plate 409. After pushing the left and right push plates to retract the locking tongue, the lens cover 402 is unlocked, and the left page turning plate 408 and the right page turning plate 409 are closed first, and then the unlocked lens cover 402 is flipped downward, and the lens cover 402 is fixed in the imaging support frame 401 by the locking tongue to prevent the mirror from being damaged by collision, and finally the upper cover 407 is flipped downward and the baffle 410 is flipped upward.

[0031] As a preferred technical solution of this embodiment, the adjustment component 2 includes a sleeve 21 that is slidably sleeved on both sides of the imaging support frame 401, the bottom of the sleeve 21 is fixedly connected to a fixed cylinder, a knob is provided on the fixed cylinder, one side of the knob is fixedly connected to the same support rod 22 that passes through the fixed cylinder, both ends of the support rod 22 are provided with first bevel teeth, the first bevel teeth are engaged with second bevel teeth, a side vertical shaft 23 is fixedly connected to the second bevel teeth, a slider 24 that is fixedly connected to the inner wall of the imaging support frame 401 is slidably sleeved on the side vertical shaft 23 through a thread, and the fixed cylinder and The fixed table top 1 is fixedly connected, and by turning the knob (the knob can also be replaced with a motor drive), the knob synchronously drives the first bevel gear on the support rod 22 to rotate, and the first bevel gear drives the second bevel gear to rotate, and the side vertical axis 23 on the second bevel gear rotates and drives the slider 24 to slide up and down through the thread, so that the imaging support frame 401 can be lifted up and down, which can meet the sitting size requirements of 90% of students from elementary school to high school. Secondly, its up and down lifting can extend or close the imaging distance to a certain extent, thereby relaxing the tension of the ciliary muscle of the eye and preventing myopia.

[0032] As the preferred technical solution of this embodiment, the function control component 3 includes a shell 31 fixedly connected to the fixed table top 1, and a plurality of fans 32 and a negative ion generator 33 are installed in the shell 31. The shell 31 is provided with an alarm setting button, a negative ion switch button, a time display button, a display screen, a dial button, a confirmation button, a light switch key, a light brightness and color temperature switch key, a timer button and a main control board. The shell 31 is provided with a negative ion outlet, and the shell 31 is fixedly connected to the fixed tube.
