A nose pad is installed inside each of the two positioning blocks. An adjusting assembly is provided between the two adjusting rods and the eyeglass frame for adjusting the position of the adjusting rods. Through the cooperation of the spherical locking block and the fixing block, the position and angle of the adjusting rods can be freely adjusted. The core wear area is concentrated on the contact surface between the spherical locking block and the fixing block.

Description

Technical Field

[0001] This utility model relates to the field of eyeglasses technology, specifically to an adjustable, non-slip nose pad eyeglass frame. Background Technology

[0002] Traditional eyeglasses mainly consist of frames and lenses. Both frames have nose pads positioned in the middle to support the frame on the wearer's nose, ensuring a stable fit. Currently, most eyeglass frames on the market use simple wire bends or plastic clips for the nose pads. For better fit, the nose pads of traditional wire-frame glasses need to be manually adjusted in position and angle using tools during the fitting process.

[0003] However, during use, over time, the position and angle of the nose pads will gradually change due to factors such as daily wearing, taking them off, and external impacts. This will affect the comfort and stability of wearing glasses, causing discomfort to the wearer. If the glasses are adjusted repeatedly, the metal wires may break, causing the nose pads to lose their proper fixation and adjustment function. This will greatly shorten the lifespan of the glasses frame and increase the user's cost and inconvenience. Utility Model Content

[0004] (a) Technical problems to be solved

[0005] To address the shortcomings of existing technologies, this invention provides an adjustable, non-slip nose pad eyeglass frame, solving the problems mentioned in the background section.

[0006] (II) Technical Solution

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] An adjustable, non-slip nose pad eyeglass frame includes an eyeglass frame, with an adjustment rod provided in the middle of each of the two eyeglass rings on the eyeglass frame. A positioning block is fixedly installed at the end of each of the two adjustment rods away from the eyeglass frame, and a nose pad is installed inside each of the two positioning blocks. An adjustment assembly is provided between the two adjustment rods and the eyeglass frame for adjusting the position of the adjustment rods.

[0009] Optionally, a spherical locking block is fixedly installed at one end of the two adjustment rods near the eyeglass frame. A fixing block is engaged with the outer periphery of the spherical locking block. A fixing bolt is threaded onto the outer periphery of the fixing block. The fixing bolt passes through and extends to the surface of the spherical locking block. A scale ring is fixedly installed at one end of the fixing block near the eyeglass frame, and the side of the scale ring away from the fixing block is fixedly installed on the eyeglass frame.

[0010] Optionally, the spherical locking block and the fixing bolt are combined to form a ball joint structure.

[0011] Optionally, the scale ring is fixedly mounted on the eyeglass frame, and a buffer pad is provided at the fixing point between the scale ring and the fixing block.

[0012] Optionally, the nose pad consists of an mounting block, an elastic airbag, a positioning mounting hole, a memory foam support layer, anti-slip protrusions, and ventilation holes. The mounting block is located on the side of the elastic airbag, the positioning mounting hole is formed on the surface of the mounting block, the outer surface of the elastic airbag is fitted with a memory foam support layer, the surface of the memory foam support layer is provided with anti-slip protrusions, and the end of the elastic airbag is provided with ventilation holes.

[0013] Optionally, the anti-slip protrusions are evenly distributed on the surface of the memory foam support layer.

[0014] This invention provides an adjustable, non-slip nose pad eyeglass frame, which has the following advantages compared with the prior art:

[0015] By using the spherical locking block and the fixed block together, the position and angle of the adjustment rod can be freely adjusted. The core wear part is concentrated on the contact surface between the spherical locking block and the fixed block. Compared with the rigid bending adjustment of the traditional one-piece metal frame (which is prone to fatigue fracture of the frame), this structure achieves angle adjustment through the relative rotation of the parts, avoiding plastic deformation of the metal material, reducing the overall wear of the adjustment rod and the eyeglass frame and improving its service life.

[0020] 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.

[0021] Please see Figures 1 to 3 This utility model provides a technical solution: an adjustable anti-slip nose pad eyeglass frame, including an eyeglass frame 1, with an adjustment rod 2 in the middle of each of the two eyeglass rings on the eyeglass frame 1, and a positioning block 3 fixedly installed at the end of each of the two adjustment rods 2 away from the eyeglass frame 1, with a nose pad 4 installed inside each of the two positioning blocks 3, and an adjustment component between the two adjustment rods 2 and the eyeglass frame 1 for adjusting the position of the adjustment rods 2. The overall structure composed of the eyeglass frame 1, adjustment rods 2, etc., can provide basic support for the eyeglasses, and the adjustment component can flexibly adjust the position of the adjustment rods 2 to adapt to different nose bridge shapes of wearers. The nose pad 4 improves wearing comfort and stability, and all components work together to ensure the fit and practicality of the eyeglasses.

[0022] Furthermore, spherical locking blocks 5 are fixedly installed at the ends of the two adjusting rods 2 near the eyeglass frame 1. A fixing block 6 is engaged with the outer periphery of the spherical locking block 5, and a fixing bolt 7 is threaded onto the outer periphery of the fixing block 6. The fixing bolt 7 penetrates and extends to the surface of the spherical locking block 5. A scale ring 8 is fixedly installed at the end of the fixing block 6 near the eyeglass frame 1, and the side of the scale ring 8 away from the fixing block 6 is fixedly installed on the eyeglass frame 1. The combination of the spherical locking block 5, the fixing block 6, and the fixing bolt 7 constitutes the adjustment and fixing structure of the adjusting rods 2. The scale ring 8 helps to ensure... The symmetrical angles of the two adjustment levers 2 improve adjustment accuracy and ensure balanced eyeglass wear. Furthermore, during use, the wearer only needs to record the corresponding scale value. If the nose pads become loose due to frequent removal or impact during daily use, the adjustment lever 2 can be quickly reset to the appropriate angle by referring to the scale, without relying on professional tools or going to the optician, greatly improving the convenience of adjustment. This adjustment method adopts a split design of "spherical locking block 5 + fixing block 6 + fixing bolt 7," with the core wear area concentrated on the contact surface between the spherical locking block 5 and the fixing block 6. Compared to the rigid bending adjustment of traditional one-piece metal frames (which easily leads to frame fatigue and breakage), this structure achieves angle adjustment through the relative rotation of components, avoiding plastic deformation of the metal material and reducing the overall wear and tear on the adjustment lever 2 and the eyeglass frame 1.

[0023] Furthermore, the spherical locking block 5 and the fixing bolt 7 combine to form a ball joint structure. The ball joint structure formed by the spherical locking block 5 and the fixing bolt 7 allows the adjusting rod 2 to rotate flexibly at multiple angles, meeting the adjustment needs in different directions and making the nose pad 4 fit the bridge of the nose more closely.

[0024] Furthermore, the scale ring 8 is fixedly installed on the eyeglass frame 1. A buffer pad 9 is provided at the fixing point between the scale ring 8 and the fixing block 6. The buffer pad 9 between the scale ring 8 and the fixing block 6 can buffer the vibration and pressure during wearing, reduce the pressure on the bridge of the nose, and improve wearing comfort.

[0025] Furthermore, the nose pad 4 is composed of a mounting block 41, an elastic airbag 42, a positioning mounting hole 43, a memory foam support layer 44, anti-slip protrusions 45, and ventilation holes 46. The mounting block 41 is located on the side of the elastic airbag 42, and the positioning mounting hole 43 is opened on the surface of the mounting block 41. The outer surface of the elastic airbag 42 is attached to the memory foam support layer 44. Each component of the nose pad 4 has a clear function. The mounting block 41 and the positioning mounting hole 43 are easy to fix with the positioning block 3. The elastic airbag 42 adapts to the deformation of the pressure. The memory foam support layer 44 can enhance the fit between the bridge of the nose and the nose pad 4. The two work together to distribute the pressure on the bridge of the nose and reduce pressure marks from long-term wear. The anti-slip protrusions 45 increase friction and effectively improve anti-slip performance, keeping the glasses stable even when sweating or exercising. The elastic airbag 42 and the memory foam support layer 44 enhance the fit and softness. The anti-slip protrusions 45 prevent slipping. The ventilation holes 46 ensure breathability, thus improving the overall wearing comfort, stability, and breathability.

[0026] Furthermore, the anti-slip protrusions 45 are evenly distributed on the surface of the memory foam support layer 44. The even distribution of the anti-slip protrusions 45 can evenly distribute the pressure, enhance the friction with the bridge of the nose, avoid local slippage, and further improve the anti-slip effect of the nose pad 4.

[0027] Working principle: Before using this adjustable anti-slip nose pad eyeglass frame, a buffer pad 9 can be placed between the fixing block 6 and the scale ring 8, and then fixed by threads. The spherical locking block 5 at one end of the adjusting rod 2 is then inserted into the fixing block 6, and the fixing bolt 7 is screwed in so that its end contacts the surface of the spherical locking block 5 but is not yet locked. Next, the mounting block 41 of the nose pad 4 is fixed to the positioning block 3 through the positioning mounting hole 43 using bolts. After the overall assembly is completed, when the user is getting glasses, the optician can observe the wearer's nose bridge shape and wearing condition, loosen the fixing bolt 7, and thus rotate the adjusting rod 2 to move the nose pad. 4. After adjusting the position and angle to fit the wearer's nose bridge, tighten the fixing bolt 7 so that the end of the bolt fits tightly with the spherical locking block 5. The angle is locked by friction to fix the position of the adjusting rod 2. During this process, not only can the symmetry of the angles on both sides be ensured by observing the scale on the scale ring 8, but after the adjustment is completed, the wearer can be informed of the corresponding scale on the scale ring 8 when the adjusting rod 2 is rotated. This allows the wearer to easily reset the rod to the original scale if it becomes loose, without having to go to the optician for adjustment. This method takes into account both fit and ease of use, enhances wearing comfort and anti-slip effect, and improves the user experience of the glasses.

[0028] The standard parts used in this embodiment can be purchased directly from the market, while the non-standard structural parts described in the specification and drawings can be processed without any doubt based on existing technical common sense. At the same time, the connection methods of each component adopt mature conventional methods in the existing technology, and the machinery, parts and equipment all adopt conventional models in the existing technology, so they will not be described in detail here.

[0029] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
