Description

Technical Field

[0001] This utility model relates to the field of eyeglass frame technology, specifically to an eyeglass frame with a hinge screw front and back structure. Background Technology

[0002] Eyeglasses are a combination of lenses and frames, used to improve vision, protect the eyes, or for decorative purposes. Eyeglasses can correct various vision problems, including nearsightedness, farsightedness, astigmatism, presbyopia, strabismus, or amblyopia.

[0003] The frame may include a bezel surrounding the lenses; a forehead bridge; a bridging element connecting the inner ends of the bezel; and two temples connecting to the outer ends of the bezel for easy wearing. Typically, lenses are mounted to the frame using screws or other fastening devices that secure them within the bezel.

[0004] However, currently the pins and the lead screws are connected using the same type of screw, but because the lead screws on the left and right ends of the frame rotate in different directions, it is easy for the screw on one end to come loose, causing the lead screw to fall off. Utility Model Content

[0005] The technical problem solved by this utility model is to provide a mirror frame with a hinge screw front and back structure, so as to solve the problems mentioned in the background art.

[0006] The technical problem solved by this utility model is achieved by the following technical solution: a mirror frame with a hinge screw front and back structure, comprising: a lens frame, wherein the lens frame is provided with lead screw connecting pins at both ends, the lead screw connecting pin at one end of the lens frame is installed on the right lead screw through a right lead screw connector, and the lead screw connecting pin at the other end of the lens frame is installed on the left lead screw through a left lead screw connector, the right lead screw connector includes a straight thread screw, the straight thread screw is tightened in the direction of the right lead screw, and the left lead screw connector includes a reverse thread screw, the reverse thread screw is tightened in the direction of the left lead screw.

[0007] Furthermore, the positive thread screw and the negative thread screw are installed on the upper side of the lead screw connection post, and the lead screw connection post is provided with screw holes corresponding to the positive thread screw and the negative thread screw.

[0008] Furthermore, the positive thread screw and the negative thread screw are installed on the lower side of the lead screw connection head, and the upper side of the lead screw connection head is provided with a screw seat corresponding to the positive thread screw and the negative thread screw.

[0009] Furthermore, the lens frame has a central crossbeam in the middle, and nose pads are provided on the lens frame at both ends of the central crossbeam.

[0010] Furthermore, the nose pad is mounted on the nose pad mounting bracket by fixing screws, and the nose pad mounting bracket is fixedly mounted on the lens frame.

[0011] Furthermore, the lens frame is provided with a lens mounting base, and the spectacle lens is fixedly mounted on the lens mounting base.

[0012] Compared with the prior art, the beneficial effects of this utility model are: the tightening direction of the positive thread screw is aligned with the right side thread position, and the tightening direction of the negative thread screw is aligned with the left side thread position, which can prevent the pin from loosening when rotating the thread and improve the overall stability of the frame.
