Abstract
Description
Technical Field
[0001] This application relates to the field of eye technology, and in particular to an adjustable nose pad and eyeglasses. Background Technology
[0002] Eyeglasses, as a widely used vision correction tool and fashion accessory, consist primarily of a frame, lenses, and temples. To optimize the wearing experience, modern eyeglasses incorporate nose pads in the area where the frame contacts the bridge of the nose. These pads are typically made of flexible materials like silicone, using their deformation properties to distribute pressure and effectively alleviate pressure marks and discomfort on the bridge of the nose caused by prolonged wear. However, traditional eyeglasses usually have fixed nose pads that are not height-adjustable. Since individual differences exist in the shape of the human nose, this results in a poor user experience.
[0003] The existing solution is to adjust the height of the nose pads using a threaded adjustment mechanism, which involves setting a rotatable screw at the connection between the nose pads and the frame to finely adjust the spacing. However, adjusting the height of the nose pads using a threaded adjustment mechanism requires a special adjustment tool, which is inconvenient, and its manufacturing process is relatively complex and has high production costs. Utility Model Content
[0004] This application provides an adjustable nose pad and glasses, aiming to solve the problems in the above-mentioned technical background where adjusting the height of the nose pad via a threaded adjustment mechanism requires the addition of a special adjustment tool, which is inconvenient to disassemble and assemble, and the manufacturing process is relatively complex and the manufacturing cost is high.

[0007] When assembling the nose pad frame and the nose pad, the insertion end is inserted into the limiting hole until the connecting block is between the two limiting blocks, then rotated 90°. At this time, the limiting protrusion and the connecting block form a mechanical stop to prevent the nose pad from coming out along the insertion direction of the nose pad frame.
[0008] Preferably, when the nose pad frame and the nose pad are assembled, the nose pad abuts against the lens rim of the frame, and the pre-tightening force generated by the elastic deformation of the nose pad is used to limit the loosening of the nose pad.

[0026] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.
[0027] This application discloses an adjustable nose pad for use with eyeglasses, including two nose pads 1 and two nose pad frames 2. One side of each nose pad 1 is provided with a connecting block 11 and a limiting hole 12 passing through the connecting block 11. The nose pad frame 2 is elongated, with one end of the nose pad frame 2 being a connecting end 21 and the other end being an insertion end 22. The connecting end 21 is connected to the frame of the eyeglasses. One side of the insertion end 22 is provided with a plurality of spaced limiting protrusions 221 along the length of the nose pad frame 2.
[0028] When assembling the nose pad frame 2 and the nose pad 1, the insertion end 22 is inserted into the limiting hole 12 until the connecting block 11 is located between the two limiting blocks and then rotated 90°. At this time, the limiting protrusion 221 and the connecting block 11 form a mechanical stop to prevent the nose pad 1 from coming out along the insertion direction of the nose pad frame 2.
[0029] Reference Figures 1 to 4The nose pads include two nose pads 1 and two nose pad frames 2. A connecting block 11 is provided on one side of each nose pad 1, and a limiting hole 12 is formed in the connecting block 11. The nose pad frame 2 connects to the eyeglass frame at one end (connecting end 21) and the other end (insertion end 22). Multiple spaced limiting protrusions 221 are provided on one side of the insertion end 22 along the length of the nose pad frame 2. The nose pad frames 2 and nose pads 1 can be made of elastic materials such as plastic or silicone, allowing for controllable elastic deformation during assembly. Specifically, during assembly of the nose pad frames 2 and nose pads 1, the insertion end 22 is first inserted into the limiting hole 12 until the connecting block 11 is positioned between the two limiting blocks, and then rotated 90°. At this time, the two opposite sidewalls of the two limiting protrusions 221 will abut against the connecting block 11, and the nose pad 1 can no longer move along the insertion direction of the nose pad skeleton 2. Furthermore, provided that the distance between the two limiting protrusions 221 is slightly less than the distance between the two end faces of the abutted connecting block 11, the two limiting protrusions 221 can undergo slight elastic deformation to clamp the connecting block 11, thereby providing a certain frictional force to prevent reverse rotation and maintain the stability of the self-locking state, so that the limiting protrusions 221 and the connecting block 11 form a two-way mechanical stop structure.
[0030] In this application, when the nose pad frame 2 and the nose pad 1 rotate relative to each other, they undergo a certain amount of elastic deformation. After rotating 90°, they return to their elastic deformation. Under normal wearing conditions without sufficient external force, the nose pad frame 2 and the nose pad 1 will not rotate. In addition, during the assembly process of the nose pad frame 2 and the nose pad 1, when the insertion end 22 rotates to 90°, the connecting block 11 can fully engage with the limiting protrusion 221. During this rotation process, the user can clearly feel the rotational resistance increasing and then decreasing, which serves as a certain indication to the user whether the operation has been completed.
[0031] Through the above technical solution, the nose pad forms a two-way mechanical stop structure with the limiting protrusion 221 of the nose pad frame 2 and the connecting block 11 of the nose pad pad 1. Users can select different positions of the limiting protrusion 221 according to the height difference of their own nose bridge to adjust the height of the nose pad. In addition, the nose pad adopts a pure mechanical connection method of insertion and rotation, which can be assembled and disassembled without additional fasteners or tools. It is convenient to assemble and disassemble, easy to maintain, and compared with the traditional screw connection method, its manufacturing process is simple and the production cost is low.
[0032] In one specific embodiment, when the nose pad frame 2 and the nose pad 1 are assembled, the nose pad 1 abuts against the lens rim of the eyeglass frame, and the pre-tightening force generated by the elastic deformation of the nose pad 1 is used to limit the loosening of the nose pad 1.
[0033] Reference Figure 1 and Figure 2When the nose pad frame 2 and nose pad 1 are assembled, one end face of the nose pad 1 will directly abut against one side of the lens ring of the frame. Since the nose pad 1 is made of elastic materials such as plastic or silicone, the nose pad 1 and the lens ring are essentially an interference fit. At this time, the pre-tightening force generated by the elastic deformation of the nose pad 1 will restrict the loosening of the nose pad 1, thereby further strengthening the connection stability between the nose pad 1 and the nose pad frame 2. In addition, when the nose pad frame 2 and nose pad 1 are assembled, the fact that one end face of the nose pad 1 directly abuts against one side of the lens ring of the frame also serves as a notification to the user that the assembly or adjustment has been completed.
[0034] Provided that the limiting protrusion 221 of the nose pad frame 2 and the limiting hole 12 of the nose pad pad 1 form the bidirectional mechanical stop structure described in the above technical solution, the cross-sections of the insertion end 22 of the nose pad frame 2 and the limiting hole 12 can be circular, elliptical, square, or other shapes. To further ensure the correct connection between the nose pad pad 1 and the nose pad frame 2, in a specific embodiment, the cross-sections of the insertion end 22 and the limiting hole 12 are rectangular. The specific implementation is as follows: the cross-section of the insertion end 22 perpendicular to the insertion direction is rectangular, and the cross-section of the limiting hole 12 perpendicular to the insertion direction is rectangular.
[0035] The rectangular cross-section has clearly defined length and width directions. When the insertion end 22 is inserted into the limiting hole 12 and rotated 90° to connect the nose pad 1, the long and short sides of the rectangle form a natural foolproof guiding structure, ensuring that the connecting block 11 can only enter between the limiting protrusions 221 in a preset orientation. This avoids directional errors during assembly, allowing the insertion end 22 and the limiting hole 12 to achieve precise directional engagement during assembly, thus ensuring the correct connection between the nose pad 1 and the nose pad frame 2. Simultaneously, the symmetrical design of the rectangular cross-section simplifies the assembly process, allowing users to more easily install and remove the nose pad. Furthermore, the planar contact of the rectangular cross-section provides a larger contact area compared to a circular cross-section, resulting in a more uniform distribution of frictional resistance between the limiting protrusions 221 and the connecting block 11, effectively improving the torsional stiffness of the mechanical stop structure.
[0036] In one specific embodiment, four sets of limiting protrusions 221 are distributed along the length direction of the insertion end 22, and each set consists of two limiting protrusions 221 that are mirror-symmetrically distributed along the direction in which the insertion end 22 is inserted into the limiting hole 12.
[0037] Specifically, refer to Figure 2 and Figure 4In this embodiment, four sets of limiting protrusions 221 are provided. Each set of limiting protrusions 221 consists of two limiting protrusions 221 that are mirror-symmetrically distributed along the direction of insertion of the insertion end 22 into the limiting hole 12. Each pair of adjacent sets forms a latch, with a total of three latches, corresponding to three preset heights for selection. Furthermore, the spacing of the latches is calculated ergonomically to ensure a stable fit after each adjustment, avoiding frequent fine-tuning. In addition, the connecting end 21 of the last set of limiting protrusions 221 along the insertion direction is integrally formed and is integrally connected to the central beam of the frame.
[0038] In one specific embodiment, the end face of the insertion end 22 is an arc-shaped surface.
[0039] Specifically, refer to Figure 4 The end face of the insertion end 22 is an arc-shaped surface. The arc-shaped end face forms a progressive contact with the edge of the limiting hole 12, which reduces frictional resistance. Furthermore, the arc-shaped surface can effectively disperse stress concentration during the assembly process, thereby extending the service life of the nose pad.
[0040] In one specific embodiment, the nose pad 1 includes a connecting block 11 and a buffer sleeve 13, the buffer sleeve 13 being provided with a groove 14, and the connecting block 11 being embedded in the groove 14.
[0041] Specifically, refer to Figure 5 The nose pad 1 includes a connecting block 11 and a cushioning sleeve 13. The cushioning sleeve 13 has a groove 14, and a blocking part extends integrally from one side edge of the groove 14. In addition to the four end faces and the bottom end face, the groove 14 also has a top end face that is parallel to the bottom end face and smaller than the bottom end face. The six end faces form a semi-closed groove 14. The connecting block 11 is made of elastic material. When the connecting block 11 is embedded in the cushioning sleeve 13, it will undergo a certain elastic deformation. Therefore, in addition to being tightly abutted against the four end faces and the bottom end face of the groove 14, the connecting block 11 will also be tightly abutted against the top end face of the groove. When the cushioning sleeve 13 ages or deforms due to long-term use, the user does not need to replace the entire nose pad assembly, but only the sleeve, which can reduce maintenance costs.
[0042] In one specific embodiment, the connecting block 11 is made of plastic and the buffer sleeve 13 is made of silicone.
[0043] The connecting block 11, made of plastic, possesses high rigidity, good formability, and a certain degree of elasticity, enabling it to withstand torsional torques during daily use and maintain the stable connection between the nose pad 1 and the nose frame 2. Simultaneously, the plastic material is easy to process and mold, meeting the complex structural design requirements of the connecting block 11. The silicone cushioning sleeve 13, with its excellent softness, elasticity, and biocompatibility, allows it to closely conform to the physiological curve of the bridge of the nose, effectively distributing pressure on the bridge, reducing indentations, and improving wearing comfort.
[0044] Through the above technical solution, the combination of the plastic connecting block 11 and the silicone cushioning sleeve 13 achieves a perfect balance between rigidity and flexibility. The plastic material provides stable support, ensuring the stability of the nose pad 1; while the silicone material provides a soft contact surface, improving wearing comfort. The two work together to ensure that the nose pad maintains stable performance while providing a comfortable wearing experience.
[0045] In one specific embodiment, the nose bridge frame 2 is made of plastic.
[0046] Compared to traditional nose pad frames made of metal, nose pad frames made of plastic have a certain degree of elastic deformation capability, allowing them to deform under external force and better adapt to different nose bridge shapes. This elastic deformation not only improves the fit between the nose pad 1 and the nose bridge but also enhances the stability of the nose pad frame 2, reducing shaking or loosening during wear.
[0047] This application also discloses an eyeglass, including a frame and two temples. The frame includes two lens rings, a central bridge connecting the two lens rings, and the aforementioned nose pads. The nose pad frame 2 and the central bridge are integrally connected. The nose pad pad 1 abuts against the lens rings. The two temples are respectively connected to the two sides of the frame.
[0048] Specifically, refer to Figure 1 and Figure 2 The present application discloses a pair of glasses, including the nose pads in any of the above embodiments. The frame of the glasses and the nose pad frame 2 are integrally connected. The specific nose pad structure has been disclosed in the foregoing embodiments and will not be repeated here.
[0049] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
