Referring to fig. 1 to 4, the present invention provides a glasses pivot positioning structure 10, the glasses pivot positioning structure 10 includes: a frame 100, a temple 200, and a shaft 300. The frame 100 is rotatably coupled to the temples 200 by the rotation shaft 300. The end of the mirror holder 100 extends to form a limiting protrusion 110, and the limiting protrusion 110 is provided with a first connection hole 111. The end of the temple 200 is opened with a rotation receiving groove 210, the rotation receiving groove 210 includes a rotation space 212 and a receiving space 213 communicated with each other, and the temple 200 is opened with a second connecting hole 211 at the rotation space 212. The limiting protrusion 110 is accommodated in the rotating space 212, the rotating shaft 300 is inserted into the first connecting hole 111 and the second connecting hole 211, and the rotating shaft 300 is rotatably connected with the limiting protrusion 110 and the ends of the temples 200 respectively. The end of the temple 200 is integrally provided with an abutting limiting part 220, the abutting limiting part 220 is located at the edge of the accommodating space 213 and is adjacent to the spectacle frame 100, the end face of the abutting limiting part 220 facing the rotating space 212 abuts against the bottom of the limiting protrusion 110, and the side of the abutting limiting part 220 facing the spectacle frame 100 abuts against the end of the spectacle frame 100. The abutment limiting portion 220 is used for limiting the limiting protrusion 110 from leaving the rotating space 212. The top of the limiting bulge 110 is integrally provided with an arc-shaped limiting part 112, and the arc-shaped limiting part 112 is provided with a abdicating notch 113; the side wall of the rotating accommodating groove 210 is integrally provided with a limiting block 230, the limiting block 230 is located in the rotating space 212, and the limiting block 230 is embedded into the abdicating notch 113 and abuts against the arc-shaped limiting part 112. The stopper 230 is used to restrict the rotation of the stopper protrusion 110 toward the receiving space 213.

The above-mentioned rotation shaft positioning structure 10 of glasses realizes the rotation connection relationship between the glasses frame 100 and the glasses legs 200 through the rotation shaft 300. The limit part 220 is abutted against the side wall of the limit protrusion 110 and the end face of the spectacle frame 100 where the limit protrusion 110 is located, so that the limit protrusion 110 is limited to leave the rotating space 212, that is, the spectacle frame 200 is limited to rotate towards the outside, and the spectacle frame 200 is prevented from swinging excessively towards the outside, so that the spectacle frame 200 is prevented from being accidentally broken. The limit protrusion 110 is limited to rotate towards the accommodating space 213 side, namely, the glasses legs 200 are limited to rotate towards the inner side through the abutting relation of the limit block 230 and the arc-shaped limit part 112, so that the unfolding state of the glasses is maintained, and the opening and closing stability is ensured. Because the temple 200 and the frame 100 have a certain deformability, the temple 200 is pushed inward to be away from the arc-shaped limiting part 112, so that the limiting block 230 and the arc-shaped limiting part 112 lose the abutting relationship, and the temple 200 can be swung inward to fold the glasses. The rotating shaft positioning structure 10 of the glasses is simple in structure and low in production cost. When the glasses are in the unfolded state, the glasses legs 200 are limited to swing randomly, and the opening and closing stability of the glasses is improved.

Frame 100 is adapted to receive lenses and temple 200 rests on the back of the user's ear to support frame 100. The rotation shaft 300 plays a role of connecting the glasses frame 100 and the glasses legs 200, and realizes a rotational connection relationship between the glasses frame 100 and the glasses legs 200, thereby facilitating folding and storage of glasses.

The mirror holder 100 is connected to the temple 200 through the stopper protrusion 110, the stopper protrusion 110 is received in the rotation space 212 defined in the temple 200, the rotation shaft 300 is mounted through the first connection hole 111 and the second connection hole 211, and the rotation connection relationship between the mirror holder 100 and the temple 200 is realized through the rotation shaft 300. In order to avoid the hole wall of the limiting protrusion 110 at the first connection hole 111 from cracking after long-term use, in one embodiment, the first connection hole 111 is opened in a middle region of the limiting protrusion 110. Therefore, the limit wall of the limit protrusion 110 at the first connection hole 111 is prevented from being too thin, and cracking is prevented, so that the holding and fixing effect on the rotating shaft 300 is enhanced. Further, in one embodiment, the second coupling hole 211 is located at a middle region of the rotation space 212. Thus, the side wall of the temple 200 at the second coupling hole 211 is prevented from being too thin, preventing cracks, and thus enhancing the holding function of the rotary shaft 300.

To facilitate the attachment of the frame 100 to the temple arms 200, in one embodiment, the rotational receptacle 210 is open on the top surface of the end of the temple arms 200. That is, the position limiting protrusion 110 is mounted on the top surface of the end of the temple 200, and the rotation shaft 300 is inserted into the first connection hole 111 and the second connection hole 211 in sequence from the top down. Thus, the user can conveniently install the glasses frame 100 and the glasses legs 200, and the assembling convenience of the rotating shaft positioning structure of the glasses is improved.

The arc-shaped limiting part 112 is used for abutting against the limiting block 230 so as to stop the glasses legs 200. The arc-shaped limiting portion 112 is provided with an abdicating notch 113 so that the limiting block 230 can be embedded into the arc-shaped limiting portion, and therefore the movement of the limiting block 230 can be limited. In order to facilitate the function of stopping the side swing of the limiting protrusion 110 to the temple 200, in one embodiment, the limiting block 230 is a quarter-circle structure, and the linear side wall of the limiting block 230 abuts against the arc-shaped limiting part 112 at the abdicating notch 113. That is, when the arc-shaped limiting portion 112 abuts against the limiting block 230, the linear side wall of the limiting block 230 is located in the receding notch 113. When the glasses are in a fully unfolded state, the straight side wall of the limiting block 230 is abutted to the arc limiting part 112 in the abdicating notch 113, and the arc limiting part 112 stops the movement of the limiting block 230, so that the glasses legs 200 are limited to swing towards the inner side. It should be noted that the limiting block 230 is a quarter-circle structure, which can be understood as the limiting block 230 is similar to a moon-shaped structure and has an arc edge and a straight edge. Further, when the glasses are in the process of being folded and turned to the unfolded state, in order to improve the swing smoothness of the glasses legs 200, the arc-shaped edge of the limiting block 230 is matched with the arc-shaped edge of the arc-shaped limiting part 112, and the arc-shaped edge wall of the limiting block 230 is used for being in sliding abutment with the arc-shaped edge wall of the arc-shaped limiting part 112. Thus, in the rotating process, the arc edge of the arc-shaped limiting part 112 abuts against and slides relative to the arc edge of the limiting block 230, so that the rotating process of the glasses legs 200 is smooth. When the glasses need to be converted from the fully unfolded state to the folded state, the glasses legs 200 are pushed and retracted by applying force inwards, so that the limit blocks 230 and the arc-shaped limit parts 112 lose the abutting relation, and at the moment, the glasses legs 200 can be swung inwards to fold the glasses. It should be noted that the spectacle frame 100 and the spectacle legs 200 may be made of resin, plastic or flexible metal, and both the spectacle legs 200 and the spectacle frame 100 have certain deformability and elastic recovery performance, so that the arc-shaped limiting part 112 and the limiting block 230 can be deformed to send a dislocation, thereby losing the abutting relationship and ensuring the stable unfolding and folding actions of the spectacles.

The abutment stopper 220 is used to restrict excessive outward swinging of the temple 200. In the present embodiment, the abutment limit part 220 is located at an outer corner of the end of the temple 200. Further, the abutting limiting portion 220 is a strip structure. The limit part 220 is abutted against the side wall of the limit protrusion 110 and against the end face of the spectacle frame 100 where the limit protrusion 110 is located, so that the spectacle frame 200 is limited from rotating towards the outside, the spectacle frame 200 is prevented from excessively swinging towards the outside, and the spectacle frame 200 is prevented from being accidentally broken.

To give the abutment stop 220 sufficient space, in one embodiment, the stop projection 110 is located adjacent the inside of the end face of the frame 100. Like this, further reduce the requirement to spacing 220 size of butt to promoted spacing 220 of butt and realized the stability of its function, when glasses were in the state of developing completely, ensured that spacing 220 of butt can effectively take place the butt with mirror holder 100, thereby avoid mirror leg 200 to swing excessively towards the outside, in order to prevent mirror leg 200 unexpected rupture. Therefore, the structure safety performance of the rotating shaft positioning structure of the glasses is improved.

In order to prevent the inner side corner of the end of the temple 200 from colliding and wearing with the lens holder 100 during the inward swing of the temple 200, in one embodiment, the inner side corner of the end of the temple 200 is rounded. The inside corner structure of the ends of temples 200 are prevented from colliding with frame 100 by providing rounded corners. Therefore, the structure safety performance of the rotating shaft positioning structure of the glasses is improved.

The technical features of the embodiments described above may be arbitrarily combined, and for the sake of brevity, all possible combinations of the technical features in the embodiments described above are not described, but should be considered as being within the scope of the present specification as long as there is no contradiction between the combinations of the technical features.
