DETAILED DESCRIPTION

[0026] The following will be described in detail with reference to the accompanying drawings Figures 1-5Further details of the application are described below.

[0027] The nose pad of the present application is detachably connected with the glasses, and comprises a pad box 1, a pad support 2 and a pad 3 for abutting against the surface of the nose. The pad support 2 is an axisymmetric one-piece structure, and the left and right ends of the pad support 2 are connected with one pad box 1 respectively. The middle part of the pad support 2 is detachably connected with the bridge 4 of the glasses. The pad box 1 has a cavity inside, and the two inner walls of the cavity are respectively provided with rotating shaft cores 11. The two rotating shaft cores 11 are symmetrically arranged. One side of the pad 3 is provided with a connecting boss 31, and the two side walls of the connecting boss 31 are provided with assembly holes 311. The connecting boss 31 is detachably embedded in the cavity of the pad box 1, and the two rotating shaft cores 11 are respectively embedded in the two assembly holes 311.

[0028] Specifically, referring to Figures 1 to 4 , the nose pad comprises a pad box 1, a pad support 2 and a pad 3 for abutting against the surface of the nose. The pad support 2 is an axisymmetric one-piece structure, and the left and right ends of the pad support 2 are connected with one pad box 1 respectively. The middle part of the pad support 2 is detachably connected with the bridge 4 of the glasses, for example, the middle part and the bridge 4 of the glasses can be detachably connected by using one of the following methods, such as screws, buckles, fasteners and the like. The inside of each of the two pad boxes 1 has a cavity, and the two opposite sides of the cavity are provided with rotating shaft cores 11. Correspondingly, the pad 3 is provided with a connecting boss 31, and the two side walls of the connecting boss 31 are provided with assembly holes 311. The connecting boss 31 is embedded in the inner cavity of the pad box 1, and the two rotating shaft cores 11 are embedded in the corresponding assembly holes 311, thereby completing the connection between the pad 3 and the pad box 1. The shapes of the rotating shaft cores 11 and the assembly holes 311 are both cylindrical, and the diameter of the assembly holes 311 is slightly larger than the diameter of the rotating shaft cores 11. When the pad 3 is connected with the pad box 1, a certain gap is left between the rotating shaft cores 11 and the assembly holes 311, so that the pad 3 can rotate around the rotating shaft cores 11. Therefore, when the nose pad is used, the angle between the pad 3 and the pad box 1 can be automatically adjusted according to the user's nose bridge to adapt to different nose shapes.

[0029] Through the above technical solution, the pad 3 and the pad box 1 of the nose pad are designed by the gap cooperation of the cylindrical rotating shaft cores 11 and the assembly holes 311, which not only ensures the rotation flexibility, but also avoids the friction and wear caused by rigid contact. The connection is stable and durable, and the pad can rotate freely around the rotating shaft cores 11, which can automatically adjust to the best fitting angle according to the user's nose bridge, so that the pad fully fits the nose bridge and the wearing comfort is high. In addition, compared with the traditional screw-connected nose pad, the nose pad proposed in the present application does not need special equipment for disassembly and assembly, and is easy to maintain.

[0030] In a specific embodiment, the two side walls of the connecting boss 31 are respectively provided with a guide groove 312 along the direction of embedding into the cavity of the lug box 1, and the guide groove 312 and the assembly hole 311 on the same side wall of the connecting boss 31 are communicated.

[0031] Specifically, referring to Figure 3 , in order to quickly and accurately embed the rotating shaft core 11 into the assembly hole 311 when the connecting boss 31 is embedded into the cavity of the lug box 1, the two side walls of the connecting boss 31 are respectively provided with a guide groove 312 along the direction of embedding into the cavity of the lug box 1, and the guide groove 312 and the assembly hole 311 are communicated. During the embedding process of the connecting boss 31 into the cavity of the lug box 1, the rotating shaft core 11 will slide along the guide groove 312 until it is embedded into the assembly hole 311,

[0032] Through the above technical solution, the groove-hole transition mode of the guide groove 312 and the assembly hole 311 has the effects of guiding and automatic alignment, and only a single push-in operation is required during installation to complete the reliable connection of the lug 3 and the lug box 1, simplifying the installation process.

[0033] In a specific embodiment, the two assembly holes 311 are communicated to form a channel through the connecting boss 31.

[0034] Specifically, referring to Figure 3 , the two assembly holes 311 are communicated to form a channel through the connecting boss 31. Compared with the non-through solution, the through assembly hole 311 is simpler in mold manufacturing process during production, thereby reducing production cost, and when demolding, the through hole allows the core to be directly separated from one end, the demolding resistance is smaller, the product jamming risk is reduced, and the production yield and efficiency are improved.

[0035] When the user wears glasses, the lug 3 is in close contact with the surface skin of the user's nose, and the sweat or oil produced by the user is easy to accumulate at the position where the lug 3 contacts with the surface skin of the user's nose. Since the lug 3 is not ventilated, it will cause irritation to the skin of the human body and make the user feel uncomfortable. In order to discharge the sweat or oil on the user's nose in time and improve the comfort when the lug 3 contacts with the surface skin of the nose, the application adopts the following implementation manner: a drainage groove 32 is arranged on the side of the lug 3 facing the user's alae nasi in the use state.

[0036] Specifically, referring to Figure 4 , the lug 3 is provided with a drainage groove 32, and the drainage groove 32 is in the shape of Y as a whole. In the use state, the sweat or oil on the user's nose will be discharged along the inner wall surface of the drainage groove, so that the skin of the nose is kept more refreshing and the wearing is more comfortable.

[0037] Because of the high strength and good durability of metal materials, and the low cost, most of the current temple supports 2 and temple boxes 1 are still mainly metal materials. With the improvement of the quality of life, people have higher and higher requirements for glasses. In some specific scenarios, more and more temple supports 2 and temple boxes 1 begin to use alloy materials. For example: users who are allergic to metal and users who require the overall weight of glasses to be relatively light, the temple supports 2 and the temple boxes 1 use alloy materials such as titanium alloy or aluminum alloy. However, compared with metal materials, alloy materials have higher costs, and the prices are much higher for ordinary users.

[0038] In the embodiments of the present application, the temple support 2 and the temple box 1 are plastic materials. Compared with metal materials, the weight of glasses when the temple support 2 and the temple box 1 are plastic materials is lighter, and is more friendly to users with metal allergies. Compared with alloy materials, the production cost of the temple support 2 and the temple box 1 made of plastic materials is lower, and can better meet the consumer demand of users.

[0039] Unlike the temple support 2 and the temple box 1, most of the current temple pads 3 are made of soft and skin-friendly, moderately elastic and biocompatible silicone materials.

[0040] In the embodiments of the present application, the temple pad 3 includes a main body of a plastic material and a buffer coating layer of a silicone material, and the buffer coating layer is combined with a side surface of the main body facing the user's nasal ala in a use state. Because the buffer coating layer of the temple pad 3 needs to be in close contact with the surface skin of the user's nose for a long time, and part of the weight of the glasses will also be applied to the surface skin of the nose through the buffer coating layer, it is more appropriate to use soft and skin-friendly, moderately elastic and biocompatible silicone materials. The main body of the temple pad 3 mainly needs to play a supporting and connecting role, and it is more appropriate to use plastic with greater structural strength. In addition, the nose pad proposed in the embodiments can be formed by low-cost forming methods such as stamping and injection molding, and the gap fit also does not require high-precision tolerance control, further reducing the production cost.

[0041] The embodiments of the present application also disclose a pair of glasses, which comprises a frame and two temples, the two temples are respectively connected to the two sides of the frame, the frame comprises two rims, a glasses bridge 4 connecting the two rims, and the above-mentioned nose pad, the glasses bridge 4 is provided with an insertion slot 41 and a fixing slot 42, the fixing slot 42 is a longitudinal slot with an opening on the top wall of the glasses bridge 4, the insertion slot 41 is a transverse slot with an opening on the side wall of the glasses bridge, and the glasses bridge 4 is further provided with a through hole 43 communicating with the bottom of the fixing slot 42 and the insertion slot 41, and the through hole 43 longitudinally penetrates through the entire glasses bridge 4;

[0042] The middle part of the support 2 is an insertion part 21, which is provided with a fixing hole 22, and the nose pad further comprises a fixing buckle 5, which comprises a connecting beam 51 and a connecting rod cap 52 with their center lines perpendicular to each other, when the nose pad is connected with the bridge 4, the insertion part 21 is inserted into the insertion slot 41, the connecting rod cap 52 is embedded into the fixing slot 42, and the connecting beam 51 penetrates through the fixing hole 22 and two corresponding through holes 43.

[0043] With reference to Figure 5 , the bridge 4 is provided with an insertion slot 41 for connecting the support 2, and the insertion slot 41 is provided with two through holes 43 on the opposite side walls, and the through hole 43 on the upper side wall of the insertion slot 41 and the through hole 43 on the lower side wall of the insertion slot 41 are in one-to-one correspondence, that is, every two corresponding through holes 43 are a group of through holes 43 penetrating through the bridge 4.

[0044] With reference to Figure 2 , the nose pad further comprises a fixing buckle 5, which comprises a connecting beam 51 and a connecting rod cap 52 connected integrally. The middle part of the support 2 is an insertion part 21, which is provided with a fixing hole 22 corresponding to the connecting beam 51.

[0045] With reference to Figure 1 , when the nose pad is connected with the bridge 4, the insertion part 21 is first inserted into the insertion slot 41, and then the connecting beam 51 is sequentially embedded into the through hole 43 on the upper side of the bridge 4, the fixing hole 22, and the through hole 43 on the lower side of the bridge 4, until the connecting rod cap 52 is arranged in the fixing slot 42, so as to realize the connection of the nose pad and the bridge 4.

[0046] Through the above technical scheme, the direct insertion of the insertion part 21 and the insertion slot 41 realizes the rapid positioning and preliminary connection of the nose pad and the bridge 4, and then the fixing buckle 5 is used to realize the rapid fixing through the penetrating assembly of “fixing slot→upper side through hole→fixing hole→lower side through hole”. Compared with the traditional screw connection, the connection mode of the present application is convenient to disassemble and assemble, the production process is simple, and the production cost is low.

[0047] It should be noted that the upper, lower, top, bottom, and middle directions mentioned in the embodiments of the present application are based on the directions when the glasses are naturally worn in the upright state of the human body or based on the front view direction, for example, “upper” refers to the direction close to the hairline of the human body (the top of the middle frame), and “lower” refers to the direction close to the lower jaw of the human body (the bottom of the middle frame).
