[0034] Currently, frame glasses that are convenient to wear based on ergonomics generally have nose pads. The nose pads are used to abut against the bridge of the user's nose and support the spectacle frame with the bridge of the user's nose as the support point. Research shows that when the nose pad is located in the middle of the bridge of the nose, it can not only meet the requirement of stable support for the spectacle frame but also meet the requirements of comfort and fit during wearing. However, since the shape of each person's bridge of the nose is different, and because the nose pads on the existing spectacle frames cannot be adjusted, the spectacle frame is supported at the starting end of the bridge of the nose when the user wears it. In this way, the spectacle frame will slide down when worn. The slid-down spectacle frame will cause the correction area of the lens to deviate from the macula area of the eyeball. Over time, it will cause the user's vision to decline. Moreover, since the starting end of the bridge of the nose is not significantly convex, when the nose pad supports at the starting end of the bridge of the nose, it will cause discomfort to the user.

[0035] The present utility model provides a spectacle frame with a nose pad 40 adjustment function, which includes a spectacle frame body 100, a nose pad body 40, and an adjustment device 50. Among them, the spectacle frame body 100 includes a first spectacle frame 10, a second spectacle frame 20, and a connecting beam 30. The connecting beam 30 is used to connect the first spectacle frame 10 and the second spectacle frame 20; the nose pad body 40 is arranged on the connecting beam 30 and is used to fit and abut against the bridge of the nose; and the adjustment device 50 is arranged on the connecting beam 30 and is used to adjust the nose pad body 40 to move along the direction from the bridge of the nose to the tip of the nose, so that the nose pad body 40 is located in the middle of the bridge of the nose.

[0036] Please refer to Figures 1 to 2 , in an embodiment of the present utility model, the spectacle frame with a nose pad 40 adjustment function includes a spectacle frame body 100, a nose pad body 40, and an adjustment device 50. Among them, the spectacle frame body includes a first spectacle frame 10, a second spectacle frame 20, a connecting beam 30, and a temple bracket 60. The connecting beam 30 is used to connect the first spectacle frame 10 and the second spectacle frame 20, and the temple bracket 60 is rotatably arranged on the sides of the first spectacle frame 10 and the second spectacle frame 20 away from the connecting beam 30, and two temple brackets 60 at different positions are at the same height. The nose pad body 40 is arranged at the lower part of the connecting beam 30, and the adjustment device 50 is also arranged on the connecting beam 30. The adjustment device 50 can adjust the position of the nose pad body 40 between the first spectacle frame 10 and the second spectacle frame 20, so that when the spectacle frame body 100 is put into use, the user can adjust the position of the nose pad body 40 according to the shape of his own bridge of the nose, so that the nose pad body 40 can move and adjust along the direction from the user's bridge of the nose to the tip of the nose, so that the nose pad body 40 can fit and abut against the middle position of the user's bridge of the nose, thereby achieving the purpose of stably supporting the spectacle frame body 100 and improving the comfort of the user wearing the spectacle frame body 100. By such a setting, the spectacle frame body 100 can be adapted to users with different-shaped bridges of the nose, and thus the adaptability of the spectacle frame body 100 is greatly improved.

[0037] In this embodiment, as Figure 2 or Figure 4 shown, an installation groove 31 is provided in the connecting beam 30, and the adjustment device 50 is arranged in the installation groove 31. In order to reduce the excessive space occupied by the adjustment device 50, therefore, in this embodiment, an installation groove 31 is provided in the connecting beam 30, and the installation groove 31 is opened towards the nose pad body 40. The adjustment device 50 is arranged in the installation groove 31. By such a setting, not only can the problem of the adjustment device 50 occupying too much space be solved, but also the weight burden of the connecting beam 30 on the spectacle frame body 100 can be reduced while maintaining the original strength of the connecting beam 30.

[0038] Specifically, in this embodiment, the adjusting device 50 includes a driving part 51 and a transmission part 52, and the driving part 51 is in transmission connection with the transmission part 52; an operation opening 32 is formed on one side of the connecting beam 30 away from the nose pad body 40, and the operation opening 32 is used for a part of the driving part 51 to protrude so as to operate the driving part 51. In this embodiment, the adjusting device 50 includes a driving part 51 and a transmission part 52, wherein the driving part 51 and the transmission part 52 are in transmission connection, and the driving part 51 drives the transmission part 52 to move to achieve the purpose of adjusting the position of the nose pad body 40 on the user's nose bridge. For the convenience of operating the driving part 51, therefore, in this embodiment, an operation opening 32 is formed on one side of the connecting beam 30 away from the nose pad body 40, that is, an operation opening 32 is formed at the bottom of the above-mentioned installation groove 31. The operation opening 32 is used for a part of the driving part 51 to extend out of the installation groove 31, so that the user can conveniently operate the driving part 51 through the operation opening 32, thereby achieving the purpose of operating the adjusting device 50.

[0039] More specifically, in this embodiment, the driving part 51 is a double-headed threaded rod, and the double-headed threaded rod includes a first threaded section 511, a second threaded section 513 and an operation section 512. The operation section 512 is used to connect the first threaded section 511 and the second threaded section 513. Spiral grooves are respectively arranged on the outer peripheries of the first threaded section 511 and the second threaded section 513, and the orientations of the two spiral grooves are opposite; the operation section 512 protrudes from the operation opening 32. In this embodiment, the driving part 51 is specifically a double-headed threaded rod, which includes a first threaded section 511, a second threaded section 513 and an operation section 512. The operation section 512 is used to connect the first threaded section 511 and the second threaded section 513. Spiral grooves are respectively arranged on the outer peripheries of the first threaded section 511 and the second threaded section 513, and the spiral groove on the first threaded section 511 and the spiral groove on the second threaded section 513 are opposite in orientation, that is to say, when the driving part 51 rotates, the moving directions of the first threaded section 511 and the second threaded section 513 for driving the transmission part 52 are opposite. In other embodiments, the first threaded section 511, the operation section 512 and the second threaded section 513 may be integrally provided, and no more limitations are made here.

[0040] Further, in this embodiment, the transmission part 52 includes a sliding member 521 and a transmission member 522. The sliding member 521 is used for driving connection with the driving part 51, and the sliding member 521 is rotationally connected to the transmission member 522. There are two sliding members 521, and the two sliding members 521 are respectively arranged on the outer circumferences of the first thread section 511 and the second thread section 513. There are two transmission members 522. One ends of the two transmission members 522 are respectively rotationally connected to the two sliding members 521, and the other ends are rotationally connected to the nose pad body 40. In this embodiment, the transmission part 52 includes a sliding member 521 and a transmission member 522, wherein the sliding member 521 is in driving connection with the driving part 51, and there are two sliding members 521 and two transmission members 522 respectively. That is, the two sliding members 521 are respectively arranged on the outer circumferences of the first thread section 511 or the second thread section 513, and the two transmission members 522 are respectively rotationally connected to the two sliding members 521. Among them, the end of the transmission member 522 far from the sliding member 521 is rotationally connected to the nose pad body 40. When the user operates the driving part 51 to rotate through the operation section 512, the two sliding members 521 will be threadedly connected to the first thread section 511 and the second thread section 513, and are connected to the nose pad body 40 through the transmission members 522. Therefore, when the first thread section 511 and the second thread section 513 rotate, the sliding members 521 will be driven to move along the extending directions of the first thread section 511 and the second thread section 513. Also, because the thread grooves on the outer circumferences of the first thread section 511 and the second thread section 513 face opposite directions, the two sliding members 521 will move in opposite directions. Assuming that the two sliding members 521 move towards the operation section 512 at the same time, then the angle between the sliding member 521 and the transmission member 522 will change, and the nose pad body 40 will be simultaneously pushed downward, so as to achieve the purpose of adjusting the position of the nose pad body 40.

[0041] In another embodiment, as Figures 3 to 4As shown in the figure, on one side of the first frame 10 and / or the second frame 20 facing the connecting beam 30, there is a sliding groove 11; at least one transmission part 52 is provided, and the transmission part 52 is threadedly connected to one end of the driving part 51 close to the sliding groove 11. On the side of the transmission part 52 away from the driving part 51, there is a protruding insertion column 523. A limiting hole 33 is opened on the side wall of the connecting beam 30. The limiting hole 33 is used for the insertion column 523 to pass through and limits the flipping of the insertion column 523 and the transmission part 52. In this embodiment, different from the above embodiment, in this embodiment, the connecting beam 30 is fixedly connected to the nose pad body 40, and by adjusting the position between the connecting beam 30, the first frame 10 and the second frame 20, the purpose of adjusting the position of the nose pad body 40 is achieved. In this embodiment, the connecting beam 30 can move between the first frame 10 and the second frame 20. To make the movement of the connecting beam 30 smoother, a sliding groove 11 can be provided on one side of the first frame 10 and / or the second frame 20 facing the connecting beam 30. In this embodiment, two sliding grooves 11 are provided, which are respectively arranged on the sides of the first frame 10 and the second frame 20 close to the connecting beam 30. Since an installation groove 31 is provided in the connecting beam 30 and the adjusting device 50 is still arranged in the installation groove 31, however, in this embodiment, the transmission part 52 of the adjusting device 50 includes an insertion column 523, and the insertion column 523 is arranged on the side of the transmission part 52 away from the driving part 51. A limiting hole 33 for the insertion column 523 to penetrate is opened on the side wall of the installation groove 31, and the limiting hole 33 can also be used to limit the rotation of the insertion column 523 and the transmission part 52 along with the driving part 51, so that the driving part 51 can smoothly drive the insertion column 523 of the transmission part 52 to reciprocate along the extending direction of the driving part 51. When the position of the nose pad body 40 needs to be adjusted, the driving part 51 can be rotated to drive the transmission part 52 to move close to the driving part 51, so that the insertion column 523 of the transmission part 52 loses the abutting function with the bottom of the sliding groove 11, and the connecting beam 30 can slide between the first frame 10 and the second frame 20 along the sliding groove 11. Since the nose pad body 40 is fixedly connected to the connecting beam 30, the position between the nose pad body 40 and the user's nose bridge can also be adjusted accordingly. After the nose pad body 40 moves to the middle position of the user's nose bridge, the driving part 51 can be driven to push the transmission part 52 to move in the direction away from the driving part 51, so that the insertion column 523 is in close contact with the bottom of the sliding groove 11, achieving a fixed effect.

[0042] In one embodiment, in this embodiment, the limiting hole 33 is a polygonal hole or an irregular hole. To prevent the transmission part 52 from rotating synchronously with the driving part 51, therefore, in this embodiment, the limiting hole 33 is a polygonal hole or an irregular hole. Of course, the hole shape of the insertion column 523 and the limiting hole 33 can be the same or different, as long as the limiting hole 33 has the effect of restricting the flipping of the insertion column 523, and no more limitations are made here.

[0043] In another embodiment, asFigure 4 As shown, at least one limiting groove 5231 is provided in the limiting hole 33, and at least one limiting protrusion 331 protrudes from the inserting column 523. The limiting protrusion 331 is inserted into the limiting groove 5231 to limit the flipping of the inserting column 523 and the transmission part 52, so that the inserting column 523 moves along the opening direction of the limiting hole 33 under the drive of the driving part 51 and abuts against the bottom of the sliding groove 11. In this embodiment, the limiting hole 33 is a conventional hole. To limit the inserting column 523, therefore, the limiting groove 5231 is provided on the inner wall of the limiting hole 33, and at the same time, the limiting protrusion 331 is protrudingly provided on the part of the inserting column 523 inserted into the limiting hole 33. The limiting protrusion 331 is in plug-in fit with the limiting groove 5231, and the limiting effect on the inserting column 523 is achieved in this way.

[0044] In one embodiment, an anti-slip layer is provided on the outer periphery of the operation section 512. In this embodiment, the operation section 512 protrudes from the above-mentioned operation port 32. To enable the user to easily operate the driving part 51 through the operation section 512, therefore, anti-slip lines are provided on the outer periphery of the operation section 512.

[0045] The present utility model also provides an optical glasses, which includes an optical lens and a spectacle frame having the nose pad 40 adjustment function as described in any of the above embodiments. The specific structure of the optical glasses refers to the above embodiments. Since the optical glasses adopt all the technical solutions of the above embodiments, it has at least all the beneficial effects brought by the technical solutions of the above embodiments, which will not be elaborated here one by one. Among them, the optical lens is arranged in the first spectacle frame 10 and the second spectacle frame 20, and the optical lens can be a protective lens, a myopia correction lens, or a hyperopia correction lens, which is not limited here too much.

[0046] The above is only an exemplary embodiment of the present utility model, and does not limit the patent scope of the present utility model. Any equivalent structural transformation made under the technical concept of the present utility model by using the content of the specification and drawings of the present utility model, or directly / indirectly applied in other related technical fields is included in the patent protection scope of the present utility model.
