Technical Field

[0001] This utility model relates to the field of eyeglass clips, specifically to an adjustable eyeglass clip. Background Technology

[0002] As nearsighted people age, they also encounter presbyopia, making it difficult to see both near and far distances simultaneously, which is very inconvenient. With the rapid development of technology and the continuous improvement of people's living standards, clip-on reading lenses have begun to appear on the market.

[0003] For example, Chinese patent CN220820408U discloses a flip-up clip-on reading glasses, including: two lenses, with a bracket fixedly connected between the two lenses; the clamping mechanism includes a stationary clamp and a movable clamp, the bracket is rotatably connected to the front side of the stationary clamp and has two fixed states: flipping up and flipping down, a hinge seat is fixedly connected to the rear side of the stationary clamp, the movable clamp has a hinge shaft in the middle, the hinge shaft is connected to the hinge seat, and a torsion spring and a pressure handle are provided on the hinge shaft; wherein, the lower ends of both the movable and stationary clamps are fitted with flexible protective sleeves, the side of the flexible protective sleeve at the end of the movable clamp facing the stationary clamp is provided with an upwardly inclined first oblique tooth, and the side of the flexible protective sleeve at the end of the stationary clamp facing the movable clamp is provided with an upwardly inclined second oblique tooth or multiple suction cups.

[0004] Although the aforementioned existing technology can be clipped onto the existing glasses of nearsighted people, it cannot be adapted to clipping onto existing glasses of different frame sizes because the original frame sizes of nearsighted people are different, and some nearsighted people may have two or three pairs of glasses with different frame sizes. The adaptability is low and it is inconvenient to use.

[0005] Therefore, there is an urgent need for an adjustable clip-on eyeglasses lens to solve the aforementioned technical problems of existing technologies. Utility Model Content

[0030] To make the objectives, technical solutions, and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this utility model.

[0031] To address the problems existing in the prior art, this utility model provides an adjustable eyeglass clip, which will be described in detail below with reference to the accompanying drawings.

[0032] Example 1

[0033] See Figures 1-7 As shown, the technical solution adopted in this specific embodiment is: an adjustable eyeglass clip, specifically including a lens 1 and a support and fixing frame 2.

[0034] The support and fixing frame 2 specifically includes a clamping part a and a connecting part b. The clamping part a has a clamp structure with a torsion spring sleeved in the middle, which clamps the adjustable eyeglass clip onto the existing eyeglasses. It should be emphasized that the specific structure of the clamping part a can be a common clip structure found on eyeglass clips on the market; this type of clip structure is a well-known technology and will not be described in detail here.

[0035] It should be specifically noted that the connecting part b has a U-shaped structure. The connecting part b specifically includes a horizontal rod 21 hinged to the clamping part a and mounting adjustment arms 22 for mounting the lens 1 located on the left and right sides of the horizontal rod 21. There is a certain angle between the mounting adjustment arms 22 and the vertical line, so that the two mounting adjustment arms 22 are arranged in a figure-eight shape.

[0036] Specifically, the mounting adjustment arm 22 includes a fixed arm 221 and a telescopic arm 222. One end of the telescopic arm 222 is telescopically disposed within the fixed arm 221, and the other end is fixedly connected to the lens 1. The fixed arm 221 is a hollow rod body with a closed upper end and an open lower end. The upper hollow part of the fixed arm 221 is a telescopic adjustment groove 2211, and the lower hollow part is a telescopic channel 2212 through which the telescopic arm 222 slides up and down. A limiting protrusion 2213 is provided on the inner wall of the telescopic adjustment groove 2211, and the limiting protrusion 2213 is integrally formed with the telescopic adjustment groove 2211. The upper side wall of the telescopic arm 222 is provided with multiple position adjustment grooves 2221 along its length direction, which can engage with the limiting protrusions 2213 to form multiple adjustment positions. The upper part of the telescopic arm 222 extends into the telescopic adjustment groove 2211 and slides up and down to extend and retract. It should be noted that when the telescopic arm 222 is fully retracted, a certain space should be reserved between the upper end of the gear adjustment part of the telescopic adjustment groove 2211 and the top wall of the telescopic adjustment groove 2211, and between the lower end of the telescopic arm 222 and the bottom wall of the telescopic adjustment groove 2211.

[0037] The telescopic arm 222 has a through hole 2222 laterally through it at the position corresponding to the gear adjustment groove 2221, thereby forming an adjustment gap with deformation capability. The side of the telescopic arm 222 facing away from the gear adjustment groove 2221 slides in cooperation with the side of the telescopic adjustment groove 2211 with the limiting protrusion 2213. Specifically, the side of the telescopic arm 222 facing away from the gear adjustment groove 2221 is a smooth plane, and a sliding cooperation is formed between the smooth plane and the opposite side of the telescopic adjustment groove 2211 with the limiting protrusion 2213.

[0038] It should be specifically noted that the concave wall surface of the gear adjustment groove 2221 matches the convex wall surface of the limiting protrusion 2213.

[0039] Furthermore, an elastic locking piece 3 is fixedly installed in the gear adjustment groove 2221. The elastic locking piece 3 is used to enhance the locking between the limiting protrusion 2213 and the gear adjustment groove 2221. When the telescopic arm 222 extends or retracts in the telescopic adjustment groove 2211, the limiting protrusion 2213 will be engaged in one of the gear adjustment grooves 2221, which will serve to fix the telescopic arm 222. The elastic locking piece 3 can provide additional elastic force to ensure the stability of the limiting protrusion 2213 in the gear adjustment groove 2221.

[0040] The elastic locking piece 3 is a thin sheet structure with a certain degree of elasticity. The lower end of the elastic locking piece 3 is fixed to the opening of the gear adjustment groove 2221, and the other end is a free end that extends upward. One side of the elastic locking piece 3 is adapted to the concave wall surface of the gear adjustment groove 2221, and the other side of the elastic locking piece 3 is adapted to the convex wall surface of the limiting protrusion 2213. When the elastic locking piece 3 is not in contact with the limiting protrusion 2213, a certain elastic adjustment space 4 is formed between the elastic locking piece 3 and the gear adjustment groove 2221.

[0041] It should be specifically noted that the telescopic channel 2212 has a first limiting boss 2214 at one end near the telescopic adjustment groove 2211, and the telescopic arm 222 forms a second limiting boss 2224 on the side corresponding to the first limiting boss 2214.

[0042] The telescopic arm 222 is provided with a limit block 2225 at the lower opening of the telescopic channel 2212.

[0043] This utility model proposes an adjustable eyeglass clip that can be telescopically adapted and clipped onto existing eyeglasses between 30mm and 50mm from position B on the frame. Position B refers to the lens height, i.e., the distance between the upper and lower outer horizontal lines of the existing eyeglass lens 1.

[0044] Example 2

[0045] See Figures 6-7 As shown, the difference between this embodiment and embodiment 1 is that a certain gap 5 is formed between the side of the telescopic arm 222 that is away from the gear adjustment groove 2221 and the telescopic adjustment groove 2211. A plurality of balls 2223 are embedded on the side of the telescopic arm 222 that is away from the gear adjustment groove 2221. The telescopic arm 222 slides in cooperation with the opposite side of the telescopic adjustment groove 2211 with the limiting protrusion 2213 through the balls 2223.

[0046] This utility model proposes an adjustable clip-on eyeglasses lens for reading glasses. For customers who already wear myopia glasses, optical shops can use this clip-on lens as a testing lens, solving the problem of the current inconvenient and inaccurate methods of testing presbyopia using optometry machines. Furthermore, many myopic people develop presbyopia as they age, requiring a separate pair of myopia and presbyopia lenses, which is expensive, uncomfortable for users, and difficult to focus, making it very inconvenient. Finally, most myopic glasses wear two to three pairs of frames of varying sizes; this clip-on lens can accommodate frames of various sizes.

[0047] In the description of this utility model, unless otherwise stated, "a plurality of" means two or more; the terms "upper," "lower," "left," "right," "inner," "outer," "front end," "rear end," "head," "tail," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. In addition, the terms "first," "second," "third," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0048] The above description is only used to illustrate the technical solution of this utility model and is not intended to limit it. Any other modifications or equivalent substitutions made by those skilled in the art to the technical solution of this utility model, as long as they do not depart from the spirit and scope of the technical solution of this utility model, should be covered within the scope of the claims of this utility model.
