Abstract
Description
Technical Field
[0001] This utility model relates to the field of vision care, and in particular to a continuously adjustable slit-type vision care device. Background Technology
[0002] In modern society, prolonged use of electronic devices and poor lifestyle habits lead to fatigue, tension, and spasms in the eye's accommodative system, resulting in various vision problems. The current conventional method of vision correction is wearing glasses. However, glasses primarily correct vision and slow the progression of myopia; they do not relieve fatigue, tension, or spasms in the eye's accommodative system, nor do they offer any health benefits for eyesight. Furthermore, the prescription for glasses increases with the years of wear. Deteriorating vision is caused by unhealthy eye habits, weakening the eye muscles' ability to adjust and adapt quickly to changes in scenery. While exercising the eye muscles could offer some health benefits, currently there are no devices specifically designed to train these muscles. Utility Model Content
[0003] To solve the above-mentioned technical problems, this utility model provides a continuously adjustable slit-type vision care device. By rotating the positive and negative threaded rods, the first and second baffles can be controlled to move closer or further apart. The change in the slit between the first and second baffles achieves depth-of-focus adjustment of the eye's image, induces eye muscle accommodation, and thus relieves fatigue, tension, spasm, etc. of the eye's accommodation system, achieving the effect of vision care.
[0004] The technical solution adopted by this utility model to solve its technical problem is: a continuously adjustable slit-type vision care device, including a frame and a window assembly;
[0005] The frame includes a lens frame corresponding to the eyes and temples on both sides of the lens frame;
[0006] The window component is disposed on the mirror frame;
[0007] The window assembly includes a positive and negative threaded rod, a first baffle, a second baffle, and a slide rod;
[0008] The positive and negative threaded rods are rotatably fitted to the mirror frame. The inner edges of the first and second baffles are arranged side by side, and one end of the first and second baffles is threadedly fitted to the positive and negative threaded rods respectively.
[0009] The slide bar is arranged parallel to the screw, and the first baffle and the second baffle are respectively slidably engaged with the slide bar.
[0010] Since the first and second baffles are threadedly adapted to the positive and negative threaded rods respectively, and the first and second baffles slide in cooperation with the slide rod respectively, rotating the positive and negative threaded rods can control the first and second baffles to move closer or further apart. The strip gap between the first and second baffles is used for the user to observe the outside world. The change in the gap realizes the depth of focus adjustment of the eye's image. The continuous change of vision from blurry to clear and from clear to blurry induces eye muscle adjustment, thereby relieving fatigue, tension, spasm, etc. of the eye's accommodation system, mobilizing eye muscle movement, and achieving the effect of maintaining eyesight.
[0011] Preferably, a sliding rod is provided at each end of the first and second baffles. This improves the stability of the sliding of the two baffles.
[0012] Preferably, adjusting knobs are provided at both ends of the positive and negative threaded rods to facilitate control of the rotation of the positive and negative threaded rods.
[0013] Preferably, the device includes a drive rod that rotates relative to the frame. The first end of the drive rod extends outward and is equipped with an adjustment knob. The second end of the drive rod is equipped with a driving bevel gear. A driven bevel gear is located in the middle of the threaded rod, and the driven bevel gear meshes with the driving bevel gear. The drive rod can be rotated from the side, causing the threaded rod to rotate.
[0014] Preferably, the frame has a front baffle and a rear baffle, with the viewing window assembly located between the front and rear baffles. The front and rear baffles each have corresponding strip-shaped windows, and the inner sides of the first and second baffles correspond to these strip-shaped windows. The cooperation of the front and rear baffles and the frame allows the viewing window assembly to be enclosed while leaving only the strip-shaped windows, thus focusing the viewer's eye on them and preventing interference from ambient light.
[0015] Preferably, the slits between the first baffle and the second baffle are horizontally distributed. This better conforms to the viewing angle of the human eye.
[0016] Preferably, the frame has a nose pad positioned downwards in the middle to provide support for the middle of the frame.
[0017] Preferably, an adjustment bracket is provided between the eyeglass frame and the nose pad. The adjustment bracket consists of an adjustment cylinder and a support rod. A screw hole is vertically provided in the middle of the eyeglass frame, and the adjustment cylinder is threaded into the screw hole. The upper end of the support rod rotates from the lower end of the adjustment cylinder and engages with the inside of the adjustment cylinder. By rotating the adjustment cylinder, the vertical position of the adjustment cylinder in the screw hole can be changed, thereby changing the vertical position of the support rod relative to the crossbar. The rotational engagement of the crossbar relative to the adjustment cylinder ensures that the nose pad always engages with the bridge of the nose.
[0018] Preferably, an adjusting head is provided at the upper end of the adjusting cylinder to facilitate rotation of the adjusting cylinder.
[0019] The beneficial effects of this utility model are:
[0020] This solution, by rotating the positive and negative threaded rods, can control the relative proximity or distance between the first and second baffles. The change in the strip gap between the first and second baffles achieves depth-of-focus adjustment of the image formed by the eye. The continuous change in vision from blurry to clear and from clear to blurry induces eye muscle adjustment, thereby relieving fatigue, tension, and spasms in the eye's accommodation system, mobilizing eye muscle movement, and achieving the effect of maintaining eye health.

[0025] To enhance understanding of this utility model, it will be described in further detail below with reference to the accompanying drawings and embodiments. These embodiments are only used to explain this utility model and do not limit the scope of protection of this utility model. Example
[0026] like Figure 1As shown, a continuously adjustable slit-type vision care device includes a frame and a window assembly. The frame includes a lens frame 13 corresponding to the eye and temples 14 on both sides of the lens frame 13. The window assembly is disposed on the lens frame 13. The window assembly includes a threaded rod 1, a first baffle 6, a second baffle 7, and a sliding rod 8. The threaded rod 1 is rotatably engaged with the lens frame 13. The inner edges of the first baffle 6 and the second baffle 7 are arranged side by side, and one end of the first baffle 6 and the second baffle 7 are respectively threaded into the threaded rod. The sliding rod 8 is arranged parallel to the threaded rod, and the first baffle 6 and the second baffle 7 are respectively slidably engaged with the sliding rod 8.
[0027] Since the first baffle 6 and the second baffle 7 are respectively threadedly adapted to the positive and negative threaded rod 1, and the first baffle 6 and the second baffle 7 are respectively slidably engaged with the slide rod 8, rotating the positive and negative threaded rod 1 can control the first baffle 6 and the second baffle 7 to move closer or further apart. The strip gap between the first baffle 6 and the second baffle 7 is used for the user to observe the outside world. The change of the gap realizes the depth of focus adjustment of the eye image. The continuous change of vision from blurry to clear and from clear to blurry induces eye muscle adjustment, thereby relieving fatigue, tension, spasm, etc. of the eye accommodation system, mobilizing eye muscle movement, and achieving the effect of maintaining eyesight.
[0028] A sliding rod 8 is provided at each end of the first baffle 6 and the second baffle 7. This improves the stability of the sliding of the two baffles.
[0029] Adjustment knobs 4 are provided at both ends of the positive and negative threaded rod 1 to facilitate control of the rotation of the positive and negative threaded rod 1.
[0030] The system includes a drive rod 5, which rotates relative to the frame 13. The first end of the drive rod 5 extends outward and is equipped with an adjustment knob 4. The second end of the drive rod 5 is equipped with a driving bevel gear 3. A driven bevel gear 2 is located in the middle of the threaded rod 1, and the driven bevel gear 2 meshes with the driving bevel gear 3. The drive rod 5 can be rotated from the side, causing the threaded rod 1 to rotate.
[0031] The frame 13 has a front baffle 16 and a rear baffle 15 respectively. The viewing window assembly is located between the front baffle 16 and the rear baffle 15. The front baffle 16 and the rear baffle 15 are provided with corresponding strip windows 17. The inner sides of the first baffle 6 and the second baffle 7 are respectively positioned corresponding to the strip windows 17. The cooperation of the front baffle 16, the rear baffle 15 and the frame 13 can, on the one hand, enclose the viewing window assembly inside, and on the other hand, leave only the strip window 17, which can focus the viewer's eye on it and avoid interference from the surrounding light.
[0032] The slits between the first baffle 6 and the second baffle 7 are horizontally distributed, which better conforms to the viewing angle of the human eye.
[0033] A nose pad 12 is provided downward in the middle of the frame to provide support for the middle of the frame 13.
[0034] An adjustment frame is provided between the eyeglass frame 13 and the nose pad 12. The adjustment frame consists of an adjustment cylinder 9 and a support rod 11. A screw hole is vertically provided in the middle of the eyeglass frame 13, and the adjustment cylinder 9 is threaded into the screw hole. The upper end of the support rod 11 rotates from the lower end of the adjustment cylinder 9 and engages with the inside of the adjustment cylinder 9. By rotating the adjustment cylinder 9, the vertical position of the adjustment cylinder 9 in the screw hole can be changed, thereby changing the vertical position of the support rod 11 relative to the crossbar. The rotational engagement of the crossbar relative to the adjustment cylinder 9 ensures that the nose pad 12 always engages with the bridge of the nose.
[0035] An adjusting head 10 is provided at the upper end of the adjusting cylinder 9 to facilitate rotation of the adjusting cylinder 9.
[0036] The beneficial effects of this utility model are:
[0037] This solution, by rotating the positive and negative threaded rod 1, can control the relative proximity or distance between the first baffle 6 and the second baffle 7. The change in the strip gap between the first baffle 6 and the second baffle 7 achieves the adjustment of the depth of focus of the eye's image. The continuous change of vision from blurry to clear and from clear to blurry induces eye muscle adjustment, thereby relieving fatigue, tension, spasm, etc. of the eye's accommodation system, mobilizing eye muscle movement, and achieving the effect of maintaining eye health.
[0038] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
