A plurality of first limit slots 13 matching the first limit protrusion 51 are provided on the side surface of the first hinged pile 11 at intervals. A mounting cavity 24 connected to the sliding groove 23 is provided in the middle beam 2, and a limit top block 6 with a T-shaped cross section matching the mounting cavity 24 is provided in the mounting cavity 24. The limit top block 6 is located between the two limit sliders 5, and a spring 7 is provided in the mounting cavity 24 between the large head end of the limit top block 6 and the side wall of the mounting cavity 24. The small head end of the limit top block 6 extends out of the mounting cavity 24 under the action of the spring 7 and is located on the inner side of the middle beam 2.
[0024] Specifically, the limit top block 6 and the spring 7 are installed in the installation cavity 24: the installation cavity 24 passes through the middle beam 2 to the outside of the middle beam 2, and a fixing cover 8 is fixedly connected to the outer surface of the middle beam 2 by screws. The spring 7 is located between the large head end of the limit top block 6 and the inner wall of the fixing cover 8. The above structure facilitates the assembly of the sliding top block.
[0025] Specifically, the rear temple 4 is foldably connected to the front temple 3: a second hinged post 41 is formed at the end of the rear temple 4, a second clamping protrusion 42 is formed at the upper and lower ends of the second hinged post 41, a second hinge groove 31 matching the second hinged post 41 is formed at the end of the front temple 3, a second clamping groove 32 matching the clamping protrusion is formed on the top wall and the bottom wall of the second hinged groove 31, the second hinged post 41 is placed in the second hinged groove 31 so that the second clamping protrusion 42 is clamped into the second clamping groove 32, thereby realizing the hinge connection between the rear temple 4 and the front temple 3.
[0026] In the above embodiment, the folding frame unit 1, the front temple 3 and the rear temple 4 are swung to make the glasses in the following manner: Figure 1When in the wearing state shown, the spring 7 pushes the limiting top block 6 to slide in the installation cavity 24 so that the large end of the limiting top block 6 is stuck between the two limiting sliding blocks 5, so that the limiting top block 6 pushes the two limiting sliding blocks 5 to slide in the sliding groove 23 toward the first hinge pile 11, and after the limiting top block 6 slides into place, the limiting sliding block 5 is pushed to slide until the first limiting protrusion 51 at its side end is stuck in the first limiting groove 13, and the limiting top block 6 applies a limit to the sliding of the limiting sliding block 5 so that the first limiting protrusion 51 is kept in the first limiting groove 13, and the rotation of the first hinge pile 11 in the first hinge groove 21 is limited, thereby applying a limit to the swing of the frame unit 1 relative to the middle beam 2, so that the frame is maintained in a wearing state flush with the middle beam 2, ensuring the stability of the glasses when worn, and the temples 4, the front temples 3 and the frame unit 1 are swung and folded to make the glasses be in a state as shown in the figure. Figure 6 When in the storage state shown in the figure, the rear temple 4 is swung inwardly relative to the front temple 3 and folded onto the front temple 3, and then the rear temple 4 and the front temple 3 are swung and folded onto the frame unit 1 relative to the frame unit 1, and then the limiting top block 6 is pressed to make the large end of the limiting top block 6 slide away from between the two limiting sliders 5 and squeeze the spring 7. At this time, the frame unit 1 is swung relative to the middle beam 2 so that the first hinged pile 11 pushes the limiting slider 5 to slide inwardly in the sliding groove 23, so that the first limiting protrusion 51 leaves the first limiting groove 13, so that the first limiting protrusion 51 releases the limiting effect on the first hinged pile 11, so that the frame unit 1 can swing freely on the middle beam 2. In the process of swinging the frame unit 1, the limiting top block 6 slides under the action of the spring 7 to reset, and the first limiting protrusion 51 at the side end of the limiting slider 5 is always against the first hinged pile 11, and when the frame unit 1 is swung to the Figure 6 When the lens frame unit 1 is in a vertical position relative to the middle beam 2 as shown, the first limiting protrusion 51 is inserted into another first limiting groove 13 to limit the rotation of the first hinged pile 11, thereby limiting the swing of the lens frame unit 1 relative to the middle beam 2, so that the lens frame unit 1 is kept in the position shown in FIG. Figure 6 The storage state shown in the figure makes the glasses more stably maintained in the storage state, which is convenient for the storage of the glasses. Through the above-mentioned structure and method, when the glasses are in the wearing state or the storage state, the limiting structure composed of the first limiting protrusion 51, the first limiting groove 13, the limiting slider 5, the limiting top block 6 and the spring 7 makes the frame and the middle beam 2 remain stable, thereby facilitating the wearing and storage of the glasses. The limiting structure is reliable and durable, which improves the user experience of the glasses when wearing or storing.
[0027] Preferably, a first limiting pile 81 is formed on the inner wall of the fixed cover 8, and a second limiting pile 61 opposite to the first limiting pile 81 is formed on the large end surface of the limiting top block 6, and the two ends of the spring 7 are respectively mounted on the first limiting pile 81 and the second limiting pile 61. The first limiting pile 81 and the second limiting pile 61 cooperate to make the spring 7 more stably maintained between the limiting top block 6 and the fixed cover 8, so as to play the role of pushing the limiting top block 6, thereby enhancing the stability when applying the limiting effect on the swing of the mirror frame.
[0028] Preferably, a second limiting protrusion 25 is formed on the outer surface of the central beam 2, and a second limiting portion 14 is formed on the side end of the frame unit 1. A second limiting groove 15 matching the first limiting protrusion 51 is opened on the inner surface of the second limiting portion 14. When the swinging frame unit 1 is swung to be flush with the central beam 2 and is in a wearing state, the second limiting portion 14 swings to the side of the second limiting protrusion 25 with the frame unit 1 so that the second limiting protrusion 25 is inserted into the second limiting groove 15, and a limit is imposed on the swing of the frame unit 1 relative to the central beam 2, so that the glasses can be more stably maintained in the wearing state, thereby improving the user experience when wearing.
[0029] Preferably, a third limiting protrusion 33 is formed at the end of the outer side surface of the front temple 3, and a third limiting portion 43 is formed at the end of the temple. A third limiting groove 44 matching the third limiting protrusion 33 is formed on the inner side surface of the third limiting portion 43. When the rear temple 4 is swung to be flush with the front temple 3 and in a wearing state, the third limiting portion 43 then swings the temple 4 to the side of the third limiting protrusion 33 so that the third limiting protrusion 33 is stuck in the third limiting groove 44, and the swing of the rear temple 4 relative to the front temple 3 is limited, so that the glasses can be more stably maintained in the wearing state, thereby improving the user experience when wearing.
[0030] Preferably, a first magnet 34 is embedded on the inner side surface of the front temple 3, and a second magnet 45 matching the first magnet 34 is embedded on the inner side surface of the rear temple 4. When the rear temple 4 is swung to fit with the front temple 3 in the storage state, the first magnet 34 and the second magnet 45 are attracted to keep the rear temple 4 and the front temple 3 in contact, so that the glasses can be more stably kept in the storage state, thereby improving the user experience when stored.
[0031] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
