Description

Technical Field

[0001] This utility model relates to the field of eyeglasses technology, and in particular to a detachable nose pad structure. Background Technology

[0002] Eyeglasses are an indispensable part of daily life. They come in various types, including prescription glasses, sunglasses, and 3D glasses, and are especially essential for people with nearsightedness. Eyeglasses consist of a frame, temples at both ends of the frame, and lenses set within the frame. The two frames are connected by a bridge, below which is a nose pad. The nose pad is the component that supports the eyeglasses on the bridge of the nose; in other words, the part that supports the frame and keeps it in place is called the nose pad.

[0003] Chinese utility model patent number 2021227797107 discloses a pair of glasses with detachable nose pads, including a main frame of glasses, which includes two frames connected by a bridge. The bridge is provided with a detachable nose pad assembly. The advantage is that because the nose pad is detachably connected to the bridge, it is easy to remove and replace the nose pad assembly when it gets dirty or even peels off due to contact with sweat and oil on the surface of the nose during use, thus affecting the wearing feel.

[0004] However, the nose pad structure described above is unstable when installed on the bridge of the glasses, and the installation is not very secure. On the other hand, its nose pad structure is also a relatively common type of nose pad, which results in low wearing comfort. Therefore, improvements are needed. Summary of the Invention

[0008] Preferably, the snap-fit ​​assembly further includes a through hole through the upper and lower connecting plates, the snap-fit ​​block is fixed on one side wall of the through hole, and the lower end of the snap-fit ​​block protrudes from the through hole and is exposed on the lower surface of the connecting plate.

[0009] Preferably, the longitudinal section of the card block is "L" shaped, with one end fixed to the side wall of the through hole away from the mirror bridge, and the other end exposed downwards below the connecting plate. The horizontal height of the upper surface of the card block is lower than the height of the upper surface of the connecting plate.

[0010] Preferably, the lower surface of the card block is provided with an inclined slope on the side away from the two leaflets, and the horizontal height of the inclined slope gradually decreases from the side away from the leaflets to the other side.

[0011] Preferably, guide blocks are respectively provided on the upper surface of the connecting plate and on both sides of the through hole, and two guide grooves are correspondingly provided on the upper groove wall of the slot for the two guide blocks to slide into.

[0012] Preferably, the stipule consists of a base layer and a covering layer from the inside out.

[0013] Preferably, the substrate layer is made of TR, PPSU, PC, titanium sheet, or stainless steel, and the covering layer is an adhesive coating.

[0014] Preferably, an air bladder chamber is provided on the opposite sides of the two stipules and between the covering layer and the base layer.

[0015] The above-mentioned detachable nose pad structure uses a connecting plate to fix the upper ends of the two nose pads together. The bridge of the eye has a slot for inserting the connecting plate. The connecting plate is snapped into the slot by a snap-fit ​​component. The two nose pads are snapped in and can be installed simultaneously and are detachable.

[0025] The embodiments of this application will be described in detail below with reference to the accompanying drawings and specific examples and application scenarios.

[0026] Example 1:

[0027] like Figures 1-6 As shown, a detachable nose pad structure includes a bridge 1 for connecting two eyeglass frames. In a specific embodiment of this utility model, a nose pad assembly is detachably provided on the bridge 1. The nose pad assembly includes two pad leaves 2, the upper ends of which are fixedly connected to each other by a connecting plate 3. A slot 4 is provided on the bridge 1 for the connecting plate 3 to be inserted, and the connecting plate 3 is snapped into the slot 4 by a snap-fit ​​assembly.

[0028] The above-mentioned detachable nose pad structure is adopted, with the upper ends of the two nose pads 2 fixedly connected to each other by a connecting plate 3. The bridge 1 is provided with a slot 4 for the connecting plate 3 to be inserted. The connecting plate 3 is snapped into the slot 4 by a snap-fit ​​component. The two nose pads 2 are snapped in and can be installed and removed at the same time, which is convenient for installation, reduces the need for multiple screws in conventional one-piece nose pads, and improves the stability after installation compared with the prior art.

[0029] In a specific embodiment of this utility model, the snap-fit ​​assembly includes a snap-fit ​​block 5 fixedly connected to the connecting plate 3. The lower end of the snap-fit ​​block 5 is horizontally lower than the lower surface of the connecting plate 3. The lower surface of the mirror bridge 1 is provided with a positioning hole 10 that communicates with the lower wall of the slot 4.

[0030] During installation, align the connecting plate 3 with the slot 4 and insert it. Because the lower end of the locking block 5 connected to the connecting plate 3 protrudes downwards, the lower wall of the slot 4 will be slightly deformed when inserted. Then, the locking block 5 will engage in the positioning hole 10 to limit the connection plate 3. When disassembly is required, simply push the locking block 5 upwards from below the positioning hole 10 while pulling the two support leaves 2 outwards to make the connecting plate 3 come out of the slot 4.

[0031] Example 2:

[0032] The difference from Embodiment 1 is that, in addition to including the structural features of the aforementioned embodiments, in this specific embodiment of the present invention, the snap-fit ​​assembly further includes a through hole 6 that passes through the upper and lower connecting plates 3, the snap-fit ​​block 5 is fixed on one side wall of the through hole 6, and the lower end of the snap-fit ​​block 5 protrudes through the through hole 6 and is exposed on the lower surface of the connecting plate 3.

[0033] In order to reduce the force on the mirror bridge 1 during installation and increase the number of times the entire assembly can be disassembled and installed, the locking block 5 is fixed on one side wall of the through hole 6, and the lower end of the locking block 5 protrudes through the through hole 6 and exposes the lower surface of the connecting plate 3. During installation, the connecting plate 3 is inserted into the slot 4, and the lower end of the locking block 5 deforms upward. As the installation of the connecting plate 3 is completed, the locking block 5 returns downward and is locked into the positioning hole 10 to limit the connection plate 3. The opening of the through hole 6 provides space for the installation and deformation of the locking block 5.

[0034] Example 3:

[0035] The difference from Embodiment 2 is that, in addition to including the structural features of the aforementioned embodiments, in this specific embodiment of the utility model, the longitudinal section of the card block 5 is "L" shaped, with one end fixed to the side wall of the through hole 6 away from the mirror bridge 1, and the other end exposed downwards below the connecting plate 3. The horizontal height of the upper surface of the card block 5 is lower than the height of the upper surface of the connecting plate 3.

[0036] The longitudinal section of the locking block 5 is "L" shaped. This structure facilitates its upward deformation during the installation of the connecting plate 3. At the same time, it further facilitates its stress. One end of the locking block 5 is fixed to the side wall of the through hole 6 away from the mirror bridge 1, and the other end protrudes downward below the connecting plate 3. The horizontal height of the upper surface of the locking block 5 is lower than the height of the upper surface of the connecting plate 3. This is to facilitate the upward deformation of the locking block 5 without it protruding from the upper surface of the connecting plate 3, so as not to affect the insertion of the connecting plate 3.

[0037] In a specific embodiment of this utility model, an inclined slope 7 is provided on the side of the lower surface of the card block 5 away from the two leaflets 2, and the horizontal height of the inclined slope 7 gradually decreases from the side away from the leaflets 2 to the other side.

[0038] The inclined slope 7 is designed to assist the locking block 5 in bending upward smoothly along the inclined slope 7 when it touches the mirror bridge 1, thereby reducing the wear on the mirror bridge 1.

[0039] In a specific embodiment of this utility model, guide blocks 8 are respectively provided on the upper surface of the connecting plate 3 and on both sides of the through hole 6, and two guide grooves 9 are correspondingly provided on the upper groove wall of the slot 4 for the two guide blocks 8 to slide into.

[0040] To further improve the stability of the connecting plate 3 when installed in the slot 4, guide blocks 8 are respectively provided on the upper surface of the connecting plate 3 and on both sides of the through hole 6. Two guide grooves 9 are correspondingly provided on the upper wall of the slot 4 for the two guide blocks 8 to slide into. The two cooperate with each other, which on the one hand facilitates the accuracy of pushing the connecting plate 3 into the slot 4, and on the other hand, makes the connecting plate 3 more stable after installation.

[0041] Example 4:

[0042] The difference from Embodiment 1 is that, in addition to including the structural features of the aforementioned embodiments, in this specific embodiment of the present invention, in order to improve the comfort of using the support leaf 2, the support leaf 2 consists of a base layer 11 and a covering layer 12 from the inside out.

[0043] In a specific embodiment of this utility model, the base layer 11 is made of TR, PPSU, PC, titanium sheet, or stainless steel, and the covering layer 12 is coated with adhesive. In a specific embodiment of this utility model, an airbag chamber 100 is provided on opposite sides of the two leaflets 2 and between the covering layer 12 and the base layer 11.

[0044] The nose pad 2 of this structure is integrally coated with adhesive on the outside of the base layer 11. The base layer 11 serves as a base, and its hardness is greater than that of the covering layer 12. The base layer 11 also has a wide range of material options, including TR, PPSU, PC, titanium sheet, or stainless steel. The adhesive contact surface is soft, and an air bladder chamber 100 is provided between the covering layer 12 and the base layer 11 to further improve the comfort of the nose pad 2 as a support for the nose.
