Screwless frame

This creation relates to a screwless spectacle frame, especially a screwless spectacle frame that is easy to assemble and disassemble.

Conventional glasses generally use screws to lock the frame and the temples, and adjust the strength of the rotation of the temples by increasing or decreasing the strength of the screws. The disadvantage of this type of arrangement is that after the glasses are folded/unfolded for many times, the screws will gradually loosen and the temples cannot be firmly connected to the frame, or even the temples can swing with gravity. When the problem occurs, the user must re-tighten the screw through the tool, which is inconvenient to use.

In order to overcome the above problems, the present invention, such as the Republic of China Announcement No. M463361, is convenient for assembling the glasses of the frame, that is, providing a screwless eyeglass. The patent mainly uses a snap member to penetrate one end of the frame, and has two pivots formed on the buckle member, and then pivots the pivot shaft to the corresponding pivot hole on the temple, so that the buckle can be opposite The pivot hole pivots to achieve the purpose of bending the frame. Since the pivot and the pivot hole can be set to an appropriate tightness during manufacture, the problem of looseness of the screw can be overcome. However, the engagement of the snap member and the frame is very tight. Once installed, the frame and the temple are difficult to disassemble. When the temple is damaged or the user wants to replace the temple style, the patent office The eyeglass structure provided cannot meet its needs. Therefore, how to improve the lack of prior technology is indeed an issue that the industry wants to overcome.

In order to achieve the above object, the present invention provides a screwless spectacle frame comprising a mirror surface, a ring frame disposed on the periphery of the mirror surface, and two mirror frames respectively connected to the two ends of the lens frame, the sides of the mirror surface being defined as the front and the back The screwless spectacle frame includes two first connecting portions respectively disposed at opposite ends of the frame, and two second connecting portions respectively disposed at one ends of each of the mirror legs. Each of the first connecting portions includes a first body disposed toward the rear surface of the mirror, a cavity recessed from the first body and facing the mirror surface, and a pivoting groove that communicates with the cavity and faces the mirror surface. a sliding slot disposed at one end of the pivoting slot and facing the mirror surface obliquely, and a positioning slot located at an end of the pivoting slot away from the sliding slot. Each of the second connecting portions includes a second body, a protrusion extending outward from the second body and corresponding to the receiving groove, and a pivot connecting the protruding block and corresponding to the pivoting groove and the positioning groove a rotating shaft, and a slider disposed at one end of the bump and having a larger radius than the pivot axis and corresponding to the chute setting. The pivoting shaft can sequentially enter the sliding slot, the pivoting slot and the positioning slot, and when the pivoting shaft abuts against the bottom end of the positioning slot, the second connecting portion can pivot corresponding to the first connecting portion.

Further, each of the first connecting portions includes a guide rail that communicates with the sliding slot, the guiding rail has a smaller width than the sliding block, and the guiding rail is obliquely open from the sliding slot facing the mirror surface.

Further, each of the positioning slots is in a snapped configuration with each of the pivoting shafts.

Therefore, this creation has the following beneficial effects compared to the prior art:

In the screwless frame of the present invention, since each of the guide rails is inclined obliquely to the mirror surface, each of the first connecting portions and each of the second connections does not occur when the glasses are folded or unfolded. The department has problems such as looseness. The user only needs to remove the temples by a simple alignment action, thereby achieving the purpose of replacing the user's preferences.
