Description

Technical Field

[0001] This utility model relates to the field of eyeglasses technology, specifically to an adjustable nose pad structure. Background Technology

[0002] As a common tool for correcting vision or protecting the eyes, the comfort and stability of eyeglasses are of paramount importance. The nose pads, as the core component of the eyeglass frame that comes into contact with the bridge of the nose, directly affect the distribution of the eyeglasses' center of gravity and the wearing experience. Because of individual differences in nose bridge height and shape among users, fixed-height nose pads often cannot meet the needs of all users, easily leading to problems such as glasses slipping down, pressure on the bridge of the nose, or a poor fit.

[0003] Existing technologies include several adjustable nose pad solutions, such as those using threaded connections or screw fastening, where height adjustment is achieved by rotating the nose pad or tightening the screw. However, these adjustment methods have significant drawbacks: First, the adjustment process usually requires specialized tools (such as screwdrivers), making it cumbersome and resulting in a poor user experience; second, the threaded structure is prone to loosening due to wear or stripping after prolonged use, leading to poor reliability and stability of the adjustment; and third, there is a risk of losing small parts such as screws. Utility Model Content

[0004] The purpose of this invention is to provide an adjustable nose pad structure that is simple in structure, easy to adjust, reliable in fixation, and can quickly achieve height adjustment without the aid of tools, in order to solve the above-mentioned problems.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: An adjustable nose pad structure includes a frame body and a nose pad. The frame body is provided with a nose pad support rod. The wall of the nose pad support rod has a plurality of slots along its length. The top side of the nose pad has an insertion groove for the bottom end of the nose pad support rod to be inserted and move up and down. The side wall of the insertion groove is fitted with a snap-fit ​​element. The snap-fit ​​element has snap-fit ​​teeth that are adapted to the slots. By snapping the snap-fit ​​teeth into the slots at different heights, the installation height of the nose pad on the frame body can be adjusted.

[0006] Preferably, a plurality of the slots cooperate with the wall of the nose support rod to form a wave-shaped structure, with a smooth transition zone in the shape of a line at the peak of the wave and at the connection between two adjacent slots. The slot teeth are V-shaped structures adapted to the slots and have an arc-shaped rounded corner structure at their bottom ends.

[0007] Preferably, the insertion groove has an upper anti-detachment part at the groove opening, and the nose support rod has a lower anti-detachment part on its rod wall below the slot. The side wall of the lower anti-detachment part slides and fits against the groove wall of the insertion groove, and the outer diameter of the lower anti-detachment part is larger than the inner diameter at the groove opening of the insertion groove.

[0008] Preferably, a clearance groove is provided on the side wall of the insertion groove and below the upper anti-detachment part, the snap-fit ​​member is embedded in the clearance groove, the top side wall of the snap-fit ​​member is provided with a protrusion flush with the side wall of the upper anti-detachment part, the side wall of the protrusion is slidably fitted with the rod wall of the nose support rod, and the snap-fit ​​teeth are fixed on the protrusion.

[0009] Preferably, the bottom end of the nose support rod is provided with a connector, the outer diameter of the connector decreases from top to bottom, and the bottom outer diameter of the connector is smaller than the inner diameter of the slot of the connector groove.

[0010] Preferably, the frame body has a riveting groove, and the top side wall of the nose pad support is provided with a riveting joint, which is inserted into the riveting groove by interference fit.

[0011] Preferably, the nose support rod and the snap-fit ​​connector are made of metal, and the nose pad is made of rubber.

[0012] By adopting the above technical solution, this utility model has the following advantages compared with the prior art: 1. This utility model provides an adjustable nose pad structure. By cooperating with the slot on the nose pad support rod and the teeth on the inner clip of the nose pad, the user only needs to apply a certain force to push and pull the nose pad to switch the teeth between slots of different heights, thereby realizing multi-level adjustment of the nose pad installation height. When disassembling, only a certain force needs to be applied to pull the nose pad to remove it for replacement. The whole process can be completed by hand without any auxiliary tools, which greatly improves the user experience and adjustment efficiency.

[0013] 2. This utility model provides an adjustable nose pad structure. The locking teeth and the locking slots form a mechanical self-locking structure. Once locked in place, it is not easy to loosen or slip off under normal wearing conditions, ensuring that the nose pad can maintain a stable position after adjustment for a long time, effectively avoiding the problem of glasses slipping due to loose nose pads.

It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0016] It should be noted that in this utility model, the terms "upper", "lower", "left", "right", "vertical", "horizontal", "inner", and "outer" are 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 are not intended to indicate or imply that the device or element of this utility model must have a specific orientation, and therefore should not be construed as a limitation of this utility model. Example

[0017] Please refer to Figures 1 to 3 As shown, this utility model discloses an adjustable nose pad structure, including a frame body 1, a nose pad support rod 2, and a nose pad 3. The frame body 1 has a riveting groove 11 at a position corresponding to the wearer's bridge of the nose. The nose pad support rod 2 is made of stainless steel or other metal materials, and its top sidewall is integrally formed or has a riveting joint 21. The riveting joint 21 is pressed into the riveting groove 11 by an interference fit, thereby achieving a firm and reliable connection between the nose pad support rod 2 and the frame body 1. The nose pad 3 is made of silicone or TR90 or other flexible rubber materials to provide a comfortable wearing experience.

[0018] The nose support rod 2 has multiple continuous slots 22 machined along its length. These slots 22 and the rod wall of the nose support rod 2 together form a continuous wave-shaped structure. The troughs of the wave-shaped structure form the slots 22, and at the crest, that is, at the connection between two adjacent slots 22, a straight transition area 23 is provided. This smooth transition area 23 makes the top of the wave-shaped structure form a brief plane or an arc surface with a large radius of curvature, rather than a sharp apex.

[0019] The top side of the nose pad 3 is provided with a insertion groove 31 for the bottom end of the nose pad support rod 2 to be inserted. The groove opening of the insertion groove 31 protrudes inward to form an upper anti-slip part 32.

[0020] The side wall of the insertion slot 31 is also provided with a clearance groove, and a snap-fit ​​part 4 is fixedly embedded in the clearance groove. The snap-fit ​​part 4 is made of metal (such as spring steel). The top side wall of the snap-fit ​​part 4 has a protrusion 41. When the snap-fit ​​part 4 is installed in place, the side wall of the protrusion 41 is flush with the side wall of the upper anti-dislodgement part 32 and slides against the wall of the nose support rod 2. The snap-fit ​​part 4 has a snap tooth 42 integrally stamped on it facing the nose support rod 2. The snap tooth 42 is a V-shaped structure adapted to the wave-shaped slot 22, and its bottom end (i.e. the tip of the V) adopts an arc-shaped rounded corner structure.

[0021] The nose support rod 2 has a lower anti-detachment part 24 located on the rod wall below the lowest slot 22. The side wall of the lower anti-detachment part 24 slides and fits against the groove wall of the insertion groove 31. The maximum outer diameter of the lower anti-detachment part 24 is larger than the inner diameter at the groove opening of the insertion groove 31 (i.e., the minimum inner diameter formed by the upper anti-detachment part 32), thereby preventing the nose support rod 2 from falling directly out of the insertion groove 31 of the nose pad 3.

[0022] The bottom end of the nose support rod 2 is provided with a connector 25. The outer diameter of the connector 25 decreases from top to bottom and is conical or wedge-shaped. The outer diameter of its bottom end is smaller than the inner diameter of the groove of the connector 31.

[0023] Working principle and adjustment process: During initial assembly, the nose support rod 2 can be easily guided and inserted into the insertion slot 31 of the nose support rod 3 using the tapered connector 25 at the bottom end. Because the nose support rod 2, which uses a rubber material for mounting the snap-fit ​​component 4, has deformable properties, the snap-fit ​​teeth 42 on the snap-fit ​​component 4 have a certain degree of elasticity. When sufficient force is applied, the snap-fit ​​teeth 42 are pressed down by the rod wall of the nose support rod 2, allowing the nose support rod 2 to continue being inserted until the lower anti-detachment part 24 passes through the slot formed by the snap-fit ​​teeth 42 and the upper anti-detachment part 32. At this point, the snap-fit ​​teeth 42, under their own elastic force, engage in a specific slot 22, completing the initial installation.

[0024] When the nose pad height needs to be adjusted, the user holds the nose pad 3 and applies a pushing or pulling force along the axial direction of the nose pad support rod 2. The applied force causes the V-shaped inclined surface of the locking tooth 42 to interact with the inclined surface of the locking groove 22, forcing the elastic locking member 4 to undergo radial elastic deformation (receding outward into the relief groove 33), thereby disengaging the locking tooth 42 from the current locking groove 22.

[0025] As the user continues to push or pull the nose pad 3, the locking teeth 42 slide along the wall of the nose pad support 2. During the sliding process, when passing through the smooth transition zone 23 at the crest, the contact area between the locking teeth 42 and the wall is relatively stable, and the sliding resistance changes gradually, providing a smooth transition. When the locking teeth 42 slides to the next target slot 22, the elastic force of the locking element 4 will drive the locking teeth 42 to quickly engage in the slot 22, accompanied by a crisp "click" sound, giving the user clear feedback that the adjustment is in place. At this time, the nose pad 3 is reliably fixed at the new height position.

[0026] By setting the upper anti-detachment part 32 and the lower anti-detachment part 24, the nose pad 3 is restricted to move within the stroke between the two. The outer diameter of the lower anti-detachment part 24 is larger than the inner diameter of the groove, which prevents the nose pad 3 from completely falling off the nose pad support rod 2 when it is adjusted downward. The upper anti-detachment part 32 works together with the protrusion 41 of the snap fastener 4 to limit the nose pad support rod 2 from extending too far upward, and works in conjunction with the lower anti-detachment part 24 to ensure that the nose pad 3 and the nose pad support rod 2 are always a whole part and will not be easily separated and lost.

[0027] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the scope of protection of this utility model. Therefore, the scope of protection of this utility model should be determined by the scope of the claims.
