Description

Technical Field

[0001] This utility model relates to the field of eyeglass frame technology, and in particular to a folding beam structure for eyeglass frames. Background Technology

[0002] Eyeglass frames are an important component of eyeglasses, primarily serving to support the lenses. Aesthetically pleasing frames also contribute to their appearance. Materials include metal, plastic or resin, and natural materials. Based on style, they can be categorized as full-rim, semi-rimless, and rimless. Eyeglass frames can have both temples folded inwards to reduce space usage. Currently, most eyeglass frames can also fold inwards to overlap the frames on both sides for easier carrying. However, most folding frames have an unsightly appearance due to the obvious fold. Therefore, a new folding bridge design is needed. Utility Model Content

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] The purpose of this invention is to provide a folding beam structure for eyeglass frames to solve the problems existing in the prior art. The folded metal frame is not visible from the front, making it more aesthetically pleasing and achieving a combination of metal and plastic.

[0019] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0020] like Figures 1-3As shown, this utility model provides a folding beam structure for a mirror frame, including a top plate 1 and two hinge plates. One end of each of the two hinge plates is hinged to both ends of the top plate 1. The beam of the mirror frame is divided into two halves, and the connecting end of the beam is provided with a slot. The other ends of the two hinge plates are respectively assembled into the slots of the two beams on both sides.

[0021] In one embodiment, the slots on both sides of the central beam are symmetrically arranged, and the length of the slots on both sides is greater than or equal to the sum of the lengths of the top plate 1 and the two hinge plates; the width of the slots on both sides of the central beam is greater than or equal to the width of the top plate 1 and the hinge plates. The top plate 1 and the hinge plates are both made of metal, and the frame is made of plastic; this allows the top plate 1 and the hinge plates to be embedded in the slots, so that the folding position and the folding metal parts are not visible from the front (i.e., the outside) of the frame, achieving a combination of metal and plastic, and making the appearance more aesthetically pleasing.

[0022] In one embodiment, the hinge plate includes a plate body 2 and a spring 3. The spring 3 has a Z-shaped structure. One end of the spring 3 is hinged to the plate body 2, and the other end of the spring 3 is rotatably installed in the rotation groove (slot) of the top plate 1 through a rotating shaft 4. The hinged ends of the plate body 2 and the spring 3 are installed in the slot by bolts.

[0023] In one embodiment, when the frame is in the open state, the ends of the two side panels 2 are joined together without gaps.

[0024] In one embodiment, a limiting plate is provided on the inner side of the top plate 1. The limiting plate is essentially the plate between the slots on both sides, and the hinge plates on both sides abut against the limiting plate after being folded.

[0025] like Figure 1 and Figure 2 As shown, in the folding beam structure of the mirror frame of this utility model, firstly, the hinged ends of the plate 2 and the spring 3 are connected, and then the end is fixed to the slot of the beam with screws. Then, the beams on both sides are joined together, and the two ends of the top plate 1 are respectively connected to the beams on both sides with bolts to realize the connection of the beams on both sides. Finally, the rotating end of the spring 3 is assembled into the rotating slot of the top plate 1 through the rotating shaft 4 to realize the installation of the entire folding beam structure of the mirror frame.

[0026] When the center beam needs to be folded, manually press and rotate the spring plates 3 on both sides. The spring plates 3 rotate around the rotating groove as the rotation axis 4, causing the plate 2 and the center beam to move inward, thus folding the center beam. Figure 3As shown, the limiting plate on the top plate 1 restricts the rotational position of the hinge plates on both sides. When the middle beam needs to be opened, the rotating end of the spring 3 is rotated in the opposite direction, causing the plate 2 and the middle beam to open outward until the two middle beams are in a straight line, and the middle beam is fully opened. In the folding middle beam structure of the mirror frame in this utility model, for the sake of aesthetics, the entire plate 2 is embedded in the slot of the middle beam. When the middle beam is in the open state, the internal folding structure is not visible from the outside.

[0027] It should be noted that, for those skilled in the art, it is obvious that this utility model is not limited to the details of the above exemplary embodiments, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this utility model.
