Description

Technical Field

[0001] This utility model belongs to the field of eyeglasses manufacturing technology and relates to an eyeglasses nose pad support. Background Technology

[0002] In everyday eyewear use, the nose pads, as a core component, play a decisive role in the wearing experience. However, traditional nose pads have significant shortcomings. Their height and angle are fixed. For example, the nose pad mounting structure described in Chinese patent number "202421241169.1" involves aligning a snap-fit ​​connector with a mounting hole and applying external force to force the connector through the hole, thus embedding the nose pad into the mounting groove and securing it to the mounting base. However, the height and shape of the nose vary greatly from person to person. Fixed-specification and fixed-installation nose pads simply cannot accommodate such diverse nose shapes and fail to meet the wearing needs of different individuals. This leads to frequent slippage of the glasses during prolonged use, requiring frequent manual adjustment and disrupting normal activity. Furthermore, the persistent discomfort can easily cause localized pressure and pain on the bridge of the nose, severely reducing wearing comfort. Utility Model Content

[0003] The purpose of this invention is to address the aforementioned problems in the existing technology by providing a height- and angle-adjustable nose pad support for eyeglasses.

[0004] The objective of this utility model can be achieved through the following technical solution: a nose pad support for eyeglasses, comprising a support body and a nose pad, wherein the support body includes a housing and a first folding slider and a second folding slider respectively hinged to both ends of the housing, the end of the first folding slider being connected to the nose pad via a universal joint, and the end of the second folding slider being fixed to the eyeglass frame, wherein an elastic element is provided inside the housing, the two ends of the elastic element being connected to the first folding slider and the second folding slider respectively, wherein when the first folding slider or the second folding slider rotates relative to the housing, the elastic element deforms; when the support body is in a folded state or a fully extended state, the elastic element returns to its original shape.

[0005] In the aforementioned eyeglass nose pad support, the side of the housing has two arc-shaped, oppositely arranged guide grooves. Both ends of the elastic element are bent to form insertion rods. The first and second folding sliders have corresponding insertion holes. The insertion rod is inserted into the insertion hole. The part of the insertion rod that passes through the insertion hole is a guide block. The two guide blocks are respectively movably located in the two guide grooves. When the support body is in a folded state or a fully extended state, the two guide blocks are respectively located at the ends of the two guide grooves on different sides.

[0006] In the aforementioned eyeglass nose pad bracket, the housing includes a first side plate, a second side plate, and a first limiting plate and a second limiting plate located at both ends of the first side plate. The guide groove is located on the first side plate. When the first folding slider and the second folding slider rotate to contact the first limiting plate or the second limiting plate, the first folding slider and the second folding slider stop rotating.

[0007] In the aforementioned eyeglass nose pad bracket, when the bracket body is in a folded state, the first folding slider is in contact with the second limiting plate, and the second folding slider is in contact with the first limiting plate.

[0008] In the aforementioned eyeglass nose pad bracket, when the first folding slider is pulled outwards alone, the guide block connected to the first folding slider moves synchronously, causing the guide block to move to the other end of the guide groove, that is, the two guide blocks are respectively located at the same side end of the guide groove, the elastic element deforms, and the end of the first folding slider contacts the first limiting plate, which is the first stretched state of the bracket body.

[0009] In the aforementioned eyeglass nose pad bracket, when the second folding slider is pulled outwards alone, the guide block connected to the second folding slider moves synchronously, causing the guide block to move to the other end of the guide groove, that is, the two guide blocks are respectively located at the same side end of the guide groove, the elastic element deforms, and the end of the second folding slider contacts the second limiting plate, which is the second pulled-up state of the bracket body.

[0010] In the aforementioned eyeglass nose pad support, both the first and second folding sliders are pulled outwards, causing the elastic element to move and deform accordingly. The two guide blocks move to the other end of the guide groove, i.e., the two guide blocks are located at the ends of the two guide grooves on different sides. The end of the first folding slider contacts the first limiting plate, and the end of the second folding slider contacts the second limiting plate. At this time, the support body is in a fully extended state.

[0011] In the aforementioned eyeglass nose pad bracket, the universal joint includes two opposing first connecting plates and two opposing second connecting plates. The included angle between the first connecting plate and the second connecting plate is >90°. The first connecting plate is vertically arranged, and the second connecting plate is horizontally arranged. A first hinge shaft for hinged to the first folding slider is passed through the two first connecting plates laterally, and a second hinge shaft for hinged to the nose pad is passed through the two second connecting plates longitudinally.

[0012] In the aforementioned eyeglass nose pad support, the elastic element is an elastic steel wire.

[0013] In the aforementioned eyeglass nose pad support, the nose pad is circular, and the side of the nose pad is curved.

[0014] In the aforementioned eyeglass nose pad support, the radius of curvature of the arc-shaped surface is 10-15mm, the thickness of the nose pad is 1-2mm, and the material of the nose pad is titanium alloy.

[0015] Compared with existing technologies, this glasses nose pad holder has the advantages of height adjustment and free angle change, improving the comfort of wearing glasses and significantly reducing the pressure on the bridge of the nose. Users can easily adjust the height of the nose pad holder by rotating the first folding slider and / or the second folding slider according to their actual needs, so that the holder body is raised, fully covering the subtle differences in the height of the bridge of the nose of different people. The nose pad is mounted on the first folding slider through a universal joint, so that the nose pad can rotate relative to the first folding slider. The nose pad can automatically and flexibly adjust to the optimal fitting angle, automatically conforming to different nose shapes, improving the wearing fit, ensuring that the glasses always fit firmly on the bridge of the nose, and fundamentally eliminating the problem of glasses slipping.

Detailed Implementation

[0021] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0022] like Figure 1-4As shown, this eyeglass nose pad support includes a support body and a nose pad 5. The support body includes a housing 1 and a first folding slider 2 and a second folding slider 3 respectively hinged to both ends of the housing 1. The end of the first folding slider 2 is connected to the nose pad 5 via a universal joint 4, and the end of the second folding slider 3 is fixed to the eyeglass frame. An elastic element 6 is provided inside the housing 1. The two ends of the elastic element 6 are connected to the first folding slider 2 and the second folding slider 3 respectively. When the first folding slider 2 or the second folding slider 3 rotates relative to the housing 1, the elastic element 6 deforms; until the support body is in a folded state or a fully extended state, the elastic element 6 returns to its original shape. The folded state described in this invention specifically refers to the initial state before extension, such as... Figure 1 As shown.

[0023] In the above technical solution: Two arc-shaped, opposing guide grooves 11 are formed on the side of the housing 1. Both ends of the elastic element 6 are bent to form insertion rods. The first folding slider 2 and the second folding slider 3 are respectively provided with insertion holes. The insertion rods are inserted into the insertion holes, connecting the elastic element 6 with the first folding slider 2 and the second folding slider 3. The portion of the insertion rod that passes through the insertion hole is a guide block 61. The two guide blocks 61 are movably located within the two guide grooves 11. When the bracket body is in a folded state or a fully extended state, the two guide blocks 61 are located at the ends of the two guide grooves 11 on different sides. Specifically, in the folded state, one guide block 61 is located at the rightmost end of the guide groove 11, and the other guide block 61 is located at the leftmost end of the guide groove 11, as shown below. Figure 1 As shown; in the fully extended state, one guide block 61 is located at the leftmost end of the guide groove 11, and the other guide block 61 is located at the rightmost end of the guide groove 11, as shown. Figure 3 As shown.

[0024] In the above technical solution: the housing 1 includes a first side plate 12, a second side plate 13, and a first limiting plate 14 and a second limiting plate 15 located at both ends of the first side plate 12. The guide groove 11 is located on the first side plate 12. When the first folding slider 2 and the second folding slider 3 rotate to contact the first limiting plate 14 or the second limiting plate 15, the first folding slider 2 and the second folding slider 3 stop rotating.

[0025] like Figure 1The diagram shows the folded state of the bracket body. The first folding slider 2 is in contact with the second limiting plate 15, and the second folding slider 3 is in contact with the first limiting plate 14. When the first folding slider 2 is pulled outward alone, the guide block 61 connected to the first folding slider 2 moves synchronously, causing the guide block 61 to move to the other end of the guide groove 11. That is, the two guide blocks 61 are located on the same side of the guide groove 11 (both are located at the left end of the guide groove 11). The elastic element 6 deforms, and the end of the first folding slider 2 contacts the first limiting plate 14. This is the first pulled-up state of the bracket body. When the second folding slider 3 is pulled outward alone, the guide block 61 connected to the second folding slider 3 moves synchronously, causing the guide block 61 to move to the other end of the guide groove 11. That is, the two guide blocks 61 are located on the same side of the guide groove 11 (both are located at the right end of the guide groove 11). The elastic element 6 deforms, and the end of the second folding slider 3 contacts the second limiting plate 15. This is the second pulled-up state of the bracket body. Both the first folding slider 2 and the second folding slider 3 are pulled outwards, causing the elastic element 6 to move and deform. The two guide blocks 61 move to the other end of their respective guide grooves 11, meaning the two guide blocks 61 are located at the ends of the two guide grooves 11 on different sides. The end of the first folding slider 2 contacts the first limiting plate 14, and the end of the second folding slider 3 contacts the second limiting plate 15. At this point, the bracket body is in a fully extended state. Figure 3 As shown. The traction force of the elastic element 6 allows the first folding slider 2 and the second folding slider 2 to be positioned in the folded state, the first extended state, the second extended state, and the fully extended state, realizing four-level height adjustment of the nose pad. It has a wide range of applications and meets the adjustment needs of different users for the nose pad height.

[0026] In the above technical solution: the universal joint 4 includes two opposing first connecting plates 41 and two opposing second connecting plates 42, with an included angle greater than 90° between the first connecting plates 41 and the second connecting plates 42. The first connecting plates 41 are vertically arranged, and the second connecting plates 42 are horizontally arranged. A first hinge shaft 43 for hinged connection of the first folding slider 2 passes horizontally through the two first connecting plates 41, and a second hinge shaft 44 for hinged connection of the nose pad 5 passes vertically through the two second connecting plates 42.

[0027] In the above technical solution: the elastic element 6 is an elastic steel wire, specifically a high-elasticity spring steel wire with a diameter of 0.4mm, which ensures that when it is subjected to the force of the first folding slider 2 and the second folding slider 3, it can bend and deform smoothly and return to its original shape stably, thus meeting the needs of long-term and frequent adjustment.

[0028] In the above technical solution: the second folding slider 3 is fixed to the frame by welding, so that the frame body becomes part of the glasses.

[0029] In the above technical solution: the nose pad 5 is circular, and the side of the nose pad 5 is an arc-shaped surface 51. The radius of curvature of the arc-shaped surface 51 is 10-15mm, and the thickness of the nose pad 5 is 1-2mm, which improves the fit and comfort between the nose pad 5 and the bridge of the nose when worn. The nose pad 5 is made of titanium alloy, which is lightweight, biocompatible, and can reduce the burden on the bridge of the nose and reduce the risk of allergies.

[0030] This nose pad holder for glasses features adjustable height and freely adjustable angle, enhancing wearing comfort and significantly reducing pressure on the bridge of the nose. Users can easily adjust the height of the nose pad holder by rotating the first folding slider 2 and / or the second folding slider 3, raising the holder to accommodate subtle differences in nose bridge height among different individuals. The nose pad 5 is mounted on the first folding slider 2 via a universal joint 4, allowing it to rotate relative to the slider 2. The nose pad 5 automatically and flexibly adjusts to the optimal fitting angle, automatically conforming to different nose shapes, improving the fit, and ensuring the glasses always stay firmly on the bridge of the nose, fundamentally preventing the glasses from slipping down.
