Description

Technical Field

[0001] This utility model relates to the field of eyeglasses technology, specifically to a progressive lens frame. Background Technology

[0002] Progressive lenses are lenses with multiple optical zones within the same lens. They can simultaneously provide different powers for distance, intermediate distance, and near distance. When wearing progressive lenses, a suitable frame is required.

[0003] When wearing progressive lenses, the wearer usually needs to adapt to the corresponding far, intermediate, and near views (top, middle, and bottom) of the lens to find the optimal wearing position. However, existing frames use a fixed structure for the nose support, making it impossible to adjust the wearing height above the nose. This results in an inability to adjust to the optimal wearing height, reducing the wearing experience. To address this, we have proposed a progressive lens frame. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technology where the wearing height of eyeglass frames above the nose cannot be adjusted, and to propose a progressive lens eyeglass frame.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a progressive lens frame, including a lens ring, a progressive lens fixedly disposed within the lens ring, temples connected to both sides of the lens ring via hinges, a central beam disposed in the middle of the lens ring, an adjustable nose wing support with an arch structure passing through the central beam, and nose pads movably connected to the bottom ends of the adjustable nose wing support; through holes for the adjustable nose wing support to pass through are provided on both sides of the central beam, a blind hole is provided on one side of the through hole, and a positioning component for limiting the adjustable nose wing support is provided in the blind hole.

[0006] Furthermore, the top of the adjustable nose wing support forms an integral handle portion.

[0007] Furthermore, the support leaf is movably connected to the end of the adjustable nasal wing support via a shaft connection, and the support leaves on both sides are symmetrically arranged on both sides of the adjustable nasal wing support, forming an inward V-shape structure.

[0008] Furthermore, the inner diameter of the through hole is adapted to the outer diameter of the columns on both sides of the adjustable nose wing support.

[0009] Furthermore, the positioning component includes a ball plunger inserted into the blind hole, a spring provided between the bottom of the blind hole and the ball plunger, and the ball protrusion of the ball plunger facing outward and tightly abutting against the adjustable nose wing support.

[0010] Furthermore, the adjustable nasal wing support has multiple positioning grooves on the uprights on both sides corresponding to the ball head plunger, and the positioning grooves are adapted to the size of the ball head plunger.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: This utility model sets an adjustable nose wing support that can be adjusted up and down on the central bridge of the frame. It can be flexibly adjusted according to the nose wing height of different wearers, so that progressive lens wearers can adjust to an optimal wearing height according to the different positions of the upper, middle and lower light intensity of the progressive lens, making the progressive lens more comfortable to wear. In addition, the adjustable nose wing support and the nose pads form an integrated arch structure, which is simple in structure, easy to adjust, and does not affect the aesthetics of the frame.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Please see Figures 1-5This utility model provides a technical solution: a progressive lens frame, including a lens ring 1, a progressive lens fixedly disposed inside the lens ring 1, temples 2 connected to both sides of the lens ring 1 by hinges 11, a central beam 3 disposed in the middle of the lens ring 1, the lens ring 1 and the central beam 3 being an integral structure, made of metal or plastic, an adjustable nose wing support 4 with an arch structure passing through the central beam 3, the top of the adjustable nose wing support 4 forming an integral handle 41, and nose pads 5 movably connected to both ends of the bottom of the adjustable nose wing support 4, the nose pads 5 being connected by a shaft. The adjustable nose wing support 4 is connected to the end of the adjustable nose wing support 4. The height of the nose pad 5 can be adjusted by lifting or pressing the adjustable nose wing support 4 through the handle part 41. It can be flexibly adjusted according to the nose wing height of different wearers, so that the wearer of progressive lenses can adjust to an optimal wearing height according to the position of different diopter levels of the progressive lenses, making the progressive lenses more comfortable to wear. The nose pads 5 are symmetrically arranged on both sides of the adjustable nose wing support 4, forming an inward V-shape structure. This arrangement can be consistent with the traditional nose pad support 5.

[0020] The central beam 3 has through holes 31 on both sides for the adjustable nasal wing support 4 to pass through. The inner diameter of the through holes 31 is adapted to the outer diameter of the uprights on both sides of the adjustable nasal wing support 4. This design ensures that the adjustable nasal wing support 4 can move stably up and down within the through holes 31. To fix the adjustable nasal wing support 4, a blind hole 32 is provided on one side of the through holes 31. A positioning component for limiting the adjustable nasal wing support 4 is provided in the blind hole 32. The positioning component includes a ball plunger 33, which is inserted into the blind hole 32. A spring 34 is provided between the bottom of the blind hole 32 and the ball plunger 33. The ball-head plunger 33 has its ball protrusion facing outward and pressing tightly against the adjustable nasal wing support 4. To further improve the stability of the limiting position, multiple positioning grooves 42 are provided on the columns on both sides of the adjustable nasal wing support 4. The positioning grooves 42 correspond to one side of the ball-head plunger 33, and the size of the positioning grooves 42 is adapted to the ball protrusion of the ball-head plunger 33. After adjustment, the ball protrusion of the ball-head plunger 33 will be stuck in the positioning groove 42. Only after applying a certain force upward or downward to the adjustable nasal wing support 4 can the adjustable nasal wing support 4 be moved, effectively ensuring the stability of the adjustable nasal wing support 4 after limiting position, making it less prone to loosening or sliding.

[0021] The progressive lens frame of this utility model has an adjustable nose wing support 4 and a nose pad 5 forming an integrated arch structure. The structure is simple, easy to adjust, and does not affect the aesthetics of the frame. It can be flexibly adjusted according to the nose wing height of different wearers, so that the wearer of progressive lenses can adjust to an optimal wearing height according to the different positions of the upper, middle and lower light intensity of the progressive lens, thereby improving the comfort of wearing progressive lenses.

[0022] Specifically, during use, by moving the adjustable nose wing support 4 up or down, the distance between the nose pad 5 and the wearer's nose wing is adjusted, thereby adjusting the support height of the nose pad 5 on the lens ring 1. After adjustment, the positioning component will effectively limit the adjustable nose wing support 4. Specifically, through the ball plunger 33 inside the positioning component and the spring 34, the ball protrusion of the ball plunger 33 is locked in the positioning groove 42 on the adjustable nose wing support 4, thereby temporarily fixing the adjustable nose wing support 4 and effectively preventing the adjustable nose wing support 4 from loosening or sliding.
