Description

Technical Field

[0001] The utility model relates to the technical field of vision correction glasses, in particular to a pair of vision correction glasses with detachable and exchangeable lenses. Background Art

[0002] Vision correction glasses usually refer to myopia glasses, hyperopia glasses or astigmatism glasses. They refer to the eyes with refractive problems that can correct vision to normal levels after wearing them. Traditional frame glasses and orthokeratology lenses, which are now gradually used more in clinical practice, are all vision correction glasses. Orthokeratology lenses can better control the speed of myopia development than traditional frame glasses. However, since they are in direct contact with the eyeball, the corresponding risks when worn will also increase. The installation of vision correction glasses is to use assembly technology to firmly combine the frame and the lens to form a pair of usable glasses. Installation of all-plastic frames: Inlay the lens into the frame from the bottom of the frame, and make the lens not loose, there is no gap between the frame pieces, and the frame has no assembly quality defects; Assembly operation of frameless frames: Since frameless frames are made by drilling holes in the lens and then combining the frame with the lens, when assembling such glasses, first drill the screw holes for fixing the frame on the lens and mill the small holes, and second, use screws to combine the lens with the frame.

[0003] When the wearer performs strenuous exercise, the glasses may fall or be hit. Since the strength of the frame is generally higher than that of the lens, the probability of the lens being damaged is higher. It is a waste to replace the entire glasses. However, under the above-mentioned lens and frame installation method, the lens replacement and installation process is relatively cumbersome and inconvenient to operate. Utility Model Content

[0032] In this solution, the locking mechanism and the supporting assembly can cooperate with each other so that the lens 3 is firmly fixed in the frame 1. When the lens 3 is damaged, the lens 3 can be quickly disassembled and installed through the locking mechanism, avoiding the cumbersome process of the traditional lens 3 installation method, and making it more convenient for people to operate. Among them, the groove 4 is used to accommodate the locking mechanism on the one hand, and on the other hand, it can limit the turning of the locking mechanism without external force; the temple 2 is used to match the ear; the lens 3 is used for vision correction.

[0033] As a further solution of the utility model, the support assembly includes a support frame 5 fixedly arranged on the inner wall of the frame 1, and the rear side wall of the lens 3 is fitted with the front side wall of the support frame 5; the inner wall of the frame 1 is fixedly connected with an elastic support sheet 6, and the front side wall of one end of the lens 3 is fitted with the rear side wall of the elastic support sheet 6.

[0034] In this embodiment, the support frame 5 is used to fix and support the rear side wall of the lens 3 , and the elastic support sheet 6 can cooperate with the support frame 5 to clamp and fix one end of the lens 3 .

[0035] As a further solution of the utility model, the locking mechanism includes a first disc 7 fixedly arranged inside the groove 4 and a second disc 8 movably arranged inside the groove 4, the front side wall of the first disc 7 is fixedly provided with a plurality of first teeth 9, the plurality of first teeth 9 form a circle of spur gear ring, the rear side wall of the second disc 8 is fixedly provided with a plurality of second teeth 10, and forms a circle of reverse gear ring; wherein the spur gear ring and the reverse gear ring are meshed with each other.

[0036] In this embodiment, when the spur gear ring and the reverse gear ring are engaged with each other, due to the action of the first teeth 9 and the second teeth 10, the second disc 8 can overcome the elastic force and rotate clockwise relative to the first disc 7, but cannot rotate counterclockwise. However, under the limiting effect of the groove 4, the second disc 8 cannot rotate clockwise. Therefore, the second disc 8 cannot rotate when the spur gear ring and the reverse gear ring are engaged with each other.

[0037] As a further solution of the utility model, the shape of the first tooth 9 is set to be vertical on one side and inclined on the other side, and the shape of the second tooth 10 is also set to be vertical on one side and inclined on the other side, wherein the inclined surface of the first tooth 9 is parallel to the inclined surface of the second tooth 10.

[0038] In this embodiment, in the absence of external force, since the inclined surface of the first tooth 9 fits with the inclined surface of the second tooth 10, and the straight surface of the first tooth 9 fits with the straight surface of the second tooth 10, when the second disk 8 rotates counterclockwise relative to the first disk 7, the straight surfaces of the multiple first teeth 9 will be locked with the straight surfaces of the multiple second teeth 10, thereby preventing the second disk 8 from rotating counterclockwise.

[0039] As a further solution of the utility model, a bracket 11 is fixedly provided inside the groove 4, and a moving rod 12 is movably connected inside the bracket 11, and a spring 13 is sleeved on the outer wall of the moving rod 12, and the two ends of the spring 13 are respectively abutted against the front side wall of the second disk 8 and the rear side wall of the bracket 11, wherein the spring 13 and the bracket 11 cooperate with each other so that the first tooth 9 and the second tooth 10 maintain a occlusal state without being subjected to external force; the front end of the moving rod 12 is fixedly connected to a rotating plate 14, and the rear side wall of the rotating plate 14 is fixedly connected to a connecting column 15, and the rear end of the connecting column 15 is fixedly connected to a fixing plate 16, and the rear side wall of the fixing plate 16 abuts against the front side wall of the other end of the lens 3, thereby cooperating with the support frame 5 and the elastic support plate 6 to fix the lens 3 inside the frame 1.

[0040] In this embodiment, due to the existence of the first spring 13 and the first spring 13 being kept in a compressed state, the elastic force of the first spring 13 can drive the second disk 8, the moving rod 12, the rotating plate 14, the connecting column 15 and the fixing plate 16 to always have an elastic force close to the first disk 7; thereby ensuring that the first teeth 9 and the second teeth 10 remain in an engaged state without being subjected to external force; since the fixing plate 16 abuts against the front side wall of the other end of the lens 3, the other end of the lens 3 is clamped and fixed by the supporting frame 5; when it is necessary to release the engagement relationship between the first teeth 9 and the second teeth 10, that is, to disassemble the lens 3, the rotating plate 14 is pulled by external force to overcome the elastic force of the first spring 13 and drive the second disk 8 away from the first disk 7, the fixing plate 16 is separated from the lens 3, and then the rotating plate 14 is rotated counterclockwise so that the fixing plate 16 rotates to the inside of the groove 4 to avoid the disassembly of the lens 3, and finally the lens 3 is removed from the inside of the frame 1.

[0041] As a further solution of the present invention, a nose pad 17 is fixedly provided on the rear side wall of the frame 1 , and the temple 2 is movably connected to the rear side wall of the frame 1 via a hinge 18 .
