Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of presbyopic glasses, and particularly relates to a presbyopic glasses frame with invisible zoom function. Background Technique
[0002] Presbyopia is a gradual decrease in the accommodation function of the human visual system. This is because the elastic modulus of the lens located directly behind the iris and pupil of the eye increases and grows. The ciliary muscle, a small muscle in the eye, pulls and pushes the lens, thereby adjusting the curvature of the lens. This adjustment of the lens curvature results in an adjustment of the eye's diopter, so that the object is located at the focal point. As an individual ages, the flexibility and elasticity of the eye's lens become poorer, and to a lesser extent, the ciliary muscle becomes weaker. These changes lead to insufficient adjustment of the eye's lens for different distances (i.e., a decrease in accommodation function), which causes objects close to the eye to appear blurred.
[0003] For traditional progressive glasses, due to the fixed pupil height and the fixed posture of the wearer, the wearer can see objects clearly normally. However, traditional progressive glasses rely on the progressive multifocal functionality of the lens itself, and have strict requirements for the production process and technology of the lens. However, errors in production are difficult to completely avoid, and continuous adjustment by wearing offline is required to achieve a satisfactory effect for customers. In addition, most of the presbyopic glasses on the market at present only have a single-direction focusing function and cannot be adjusted arbitrarily, which easily causes visual fatigue.
[0004] Therefore, this solution proposes a presbyopic glasses frame with invisible zoom function, which solves the technical problem of how to conveniently and quickly adjust the pupil height, so that objects at different distances can be seen clearly under different circumstances. Content of the Utility Model
[0005] The purpose of the utility model is to provide a presbyopic glasses frame with invisible zoom function, which solves the technical problem of how to conveniently and quickly adjust the pupil height. The wearer can change the pupil height by adjusting the flexible nose pad, so as to obtain the best wearing experience in different postures, scenarios, wearing habits and directions, and also avoid the high cost caused by relying on the progressive multifocal functionality of the lens itself in the past.
[0006] A presbyopic glasses frame with invisible zoom function includes a frame, lenses fixed on the frame, and two temple arms rotatably connected to both ends of the frame at one end. Fixed parts are respectively and fixedly arranged on both sides of the central axis of the frame. Rotating structures are respectively rotatably arranged on the two fixed parts, and flexible nose pads are detachably sleeved on the outer sides of the rotating structures.
[0007] The fixing part is T-shaped and includes a positioning part, a vertical part vertically connected to one end of the positioning part. An opening groove is provided at the other end of the vertical part. Arc-shaped column grooves are respectively provided on both inner sides of the opening groove, and a buffer groove is provided at the inner bottom end of the opening groove;
[0008] A plurality of card slots are provided on the side surfaces at both ends of the positioning part.
[0009] The rotating structure includes a first rotating part and a second rotating part fixedly connected to the first rotating part. A positioning groove is provided on the outer side of the second rotating part. The two inner end faces of the positioning groove are respectively vertically and fixedly connected to both ends of the clamping column, and two outer end faces parallel to the inner end faces are respectively fixed with protruding parts. A stop block is fixedly arranged on the clamping column;
[0010] Adjusting strips are fixed on the outer sides at both ends of the positioning groove. The two ends of the adjusting strips are respectively vertically connected to the inner end face and the outer end face;
[0011] The clamping column is movably clamped in the arc-shaped column groove, and the adjusting strip is movably switched and connected in a plurality of the card slots.

An embedding groove is provided on the clamping part, and the embedding groove covers the outer sides of the fixing part and the rotating structure.
[0013] There are three card slots.
[0014] The flexible nose pad is made of rubber material.
[0015] The technical effects of the present utility model are as follows:
[0016] (1) For the presbyopic glasses proposed in this solution, the focusing function point is transferred from the lens itself to the frame. The focusing state of the lens can be correspondingly changed by finely adjusting the flexible nose pad (with three gears of far, medium and near), so as to quickly adapt to different scenarios. Therefore, users can finely adjust the best adaptation state by themselves, and the user satisfaction is greatly improved;
[0017] (2) This solution can be fully adapted to various scenarios, and this product can focus 360° in all directions. The focusing direction of the lens can be adjusted by adjusting the flexible nose pad. Brief Description of the Drawings

Detailed implementation manners
[0027] In order to more clearly illustrate the technical features of the present solution, the present solution will be described below through specific implementation manners.
[0028] See Figures 1 - 8 , a presbyopic spectacle frame with invisible zooming, including a frame 1, lenses 2 fixed on the frame 1, and two temples 3 rotatably connected to both ends of the frame 1 at one end. Fixing parts 44 are respectively and fixedly arranged on both sides of the central axis of the frame 1. Rotating structures are respectively rotatably arranged on the two fixing parts 44, and a flexible nose pad 4 is detachably sleeved on the outer side of the rotating structure.
[0029] The fixing part 44 is in a T shape and includes a positioning part and a vertical part vertically connected to one end of the positioning part. An opening groove is arranged at the other end of the vertical part. Arc-shaped column grooves 45 are respectively arranged on both sides inside the opening groove, and a buffer groove 451 is arranged at the bottom end inside the opening groove;
[0030] A plurality of clamping grooves 46 are formed on both side surfaces at both ends of the positioning part.
[0031] The rotating structure includes a first rotating part 41 and a second rotating part 42 fixedly connected to the first rotating part 41. A positioning groove is formed on the outer side of the second rotating part 42. The two inner end faces of the positioning groove are perpendicularly and fixedly connected to both ends of a clamping column 431, and two outer end faces parallel to the inner end faces are respectively fixed with protruding parts 43. A stop block 433 is fixedly arranged on the clamping column 431;
[0032] Adjusting strips 432 are fixed on the outer sides of both ends of the positioning groove. Both ends of the adjusting strips 432 are perpendicularly connected to the inner end faces and the outer end faces respectively;
[0033] The clamping column 431 is movably clamped in an arc-shaped column groove 45, and the adjusting strips 432 are movably and switchably connected in a plurality of clamping grooves 46.
[0034] Among them, the stop block 433 is located at the outer port position of the opening groove. The stop block 433 can switch and contact the two inner sides of the outer port of the opening groove to achieve the limiting effect and prevent the rotating structure from rotating too much and causing detachment; the setting of the protruding parts 43 enables the protruding parts 43 to be more firmly clamped in the embedding groove 40 to avoid the phenomenon of detachment.
[0035] The flexible nose pad 4 includes two clamping parts 7, a supporting part 5 connected to the clamping parts 7, and a connecting part 6 connected to the two clamping parts 7. An embedding groove 40 is formed on the clamping part 7, and the embedding groove 40 covers the outside of the fixing part 44 and the rotating structure.
[0036] There are three clamping grooves 46.
[0037] It should be noted that the internal structure of the embedding groove 40 is the same as or slightly larger than the external structures and dimensions of the fixing part 44 and the rotating structure to facilitate accommodation. Since the flexible nose pad 4 is integrally made of a flexible material (such as rubber), there is no big problem for the embedding groove 40 to accommodate the fixing part 44 and the rotating structure; the protruding parts 43 designed on the rotating structure are embedded in the embedding groove 40, making the positioning of the flexible nose pad 4 more stable.
[0038] The flexible nose pad 4 is made of rubber.
[0039] The specific working process of the present utility model:
[0040] For the specific shapes and structures of the fixing part 44, the vertical part, the first rotating part 41, the second rotating part 42, the protruding parts 43, the clamping parts 7, the supporting part 5, and the connecting part 6 in this solution, they shall be subject to the markings in the drawings of this solution, but they may not be limited to the structural shapes provided in this solution. The principle is that they shall achieve the functional purpose.
[0041] The card slots 46 in this solution are arranged in sequence from left to right, and there are three of them. By bending the rotating part 1 41 and the rotating part 2 42, the adjustment bar 432 switches back and forth between different adjacent card slots 46, and the card column 431 is also rotated and adjusted at a small angle in the arc column groove 45, so that the rotating structure is rotated and adjusted as a whole, so that the position of the support part 5 in the flexible nose pad 4 can be changed to different gears, that is, adjusted left and right to adjust the focus state, and can be adjusted according to the actual application scenario, so that people can see objects at different distances clearly. Figures 6 - 8 The direction indicated by the arrow in the figure is the direction of the gear position, which is also the direction of the rotating structure. When the two rotating structures are close to each other, it is suitable for close-up observation. When the two rotating structures are far away from each other, it is suitable for long-distance observation. When the two rotating structures are in the middle gear, it is suitable for observing scenes at a moderate distance. As for the observation distance for the long-distance, close-up, and middle area, it depends on the specific lens power, because lenses of different powers will have different observation distances, which will not be elaborated here.
[0042] The buffer groove 451 is designed so that the upper and lower parts of the opening groove become elastic, that is, the vertical part is easy to be slightly deformed, thereby facilitating the rotation adjustment of the second rotating part 42 on the fixed part 44.
[0043] Technical features not described in the present invention can be achieved through or by adopting existing technologies, and will not be elaborated here. Of course, the above description is not a limitation of the present invention, and the present invention is not limited to the above examples. Changes, modifications, additions or substitutions made by ordinary technicians in this technical field within the essential scope of the present invention should also fall within the scope of protection of the present invention.
