[0026] Reference Figure 1 - Figure 4 The utility model provides an embodiment: a hinge structure for glasses, comprising a card block 1, the outer wall of the card block 1 is fixedly connected with an elastic fixing sheet 2, the outer wall of the card block 1 is provided with a card slot 3, the inner wall of the card block 1 is fitted with a first sheet-shaped card shaft 4, the inner wall of the card block 1 is fitted with a second sheet-shaped card shaft 5, the inner wall of the first sheet-shaped card shaft 4 is rotatably connected with a first card shaft 6, the lower surface of the first card shaft 6 is fixedly connected with a connecting block 7, the lower surface of the connecting block 7 is fixedly connected with a second card shaft 8, the outer wall of the second card shaft 8 is slidably connected to the inner wall of the second sheet-shaped card shaft 5, the outer wall of the connecting block 7 is fixedly connected with a temple 9, and the outer wall of the card block 1 is provided with a fixing component;
[0027] Specifically, rotating the temple 9 drives the connecting block 7 to rotate, which in turn drives the first clamping shaft 6 to rotate on the inner wall of the first sheet-shaped clamping shaft 4, and also causes the second clamping shaft 8 fixedly connected to the lower surface of the connecting block 7 to rotate on the inner wall of the second sheet-shaped clamping shaft 5. The first sheet-shaped clamping shaft 4 and the second sheet-shaped clamping shaft 5 are respectively fitted with the inner walls of the clamping block 1. When the connecting block 7 rotates, the elastic fixing plate 2 will be elastically deformed.
[0028] Reference Figure 1 and Figure 2 The fixing assembly includes a fixing buckle 11, the outer wall of the fixing buckle 11 is slidably connected to the inner wall of the card slot 3, the outer wall of the elastic fixing sheet 2 is fitted with the outer wall of the fixing buckle 11, and the outer wall of the card block 1 is fitted with the outer wall of the fixing buckle 11;
[0029] Specifically, due to the fixing effect of the fixing buckle 11, the temple 9 will not cause the connecting block 7 to be detached when rotating.
[0030] Reference Figure 1 The outer wall of the temple 9 is fixedly connected with a leg support 14;
[0031] Specifically, the leg support 14 helps keep the glasses in the correct position by supporting and fixing the ears of the glasses.
[0032] Reference Figure 1 The outer wall of the card block 1 is fixedly connected to the outer frame 12; the inner wall of the outer frame 12 is fixedly connected to the inner frame 10;
[0033] Specifically, the double-frame design can increase the layering and three-dimensional sense of the glasses, making the glasses look more fashionable and personalized, suitable for different aesthetic needs.
[0034] Reference Figure 1 , the inner wall of the inner frame 10 is provided with a lens 13, and the material of the lens 13 is glass;
[0035] Specifically, the glass 13 lenses have high optical clarity and scratch resistance.
[0036] Reference Figure 5 , the elastic fixing sheet 2 is made of a highly elastic stainless steel sheet;

[0038] Reference Figure 1 , the material of the leg support 14 is plastic;
[0039] Specifically, plastic is generally lighter than metal frames and comes in more color and texture options.
[0040] Working principle: rotating the temple 9 drives the connecting block 7 to rotate, thereby driving the first clamping shaft 6 to rotate on the inner wall of the first sheet-shaped clamping shaft 4, and also driving the second clamping shaft 8 fixedly connected to the lower surface of the connecting block 7 to rotate on the inner wall of the second sheet-shaped clamping shaft 5, wherein the first sheet-shaped clamping shaft 4 and the second sheet-shaped clamping shaft 5 here are respectively fitted with the inner wall of the clamping block 1, and when the connecting block 7 is rotated, the elastic fixing plate 2 will be elastically deformed, but due to the fixing effect of the fixing buckle 11, the temple 9 will not drive the connecting block 7 to disengage when rotating, thereby realizing a screwless rotating shaft hinge design, which is simple, firm, and not easy to loosen, thereby improving the stability and durability of the glasses. When the structure needs to be assembled, first slide the first sheet-shaped clamping shaft 4 and the second sheet-shaped clamping shaft 5 on the outer walls of the first clamping shaft 6 and the second clamping shaft 8 respectively, Then, the first sheet-shaped card axis 4 and the second sheet-shaped card axis 5 are engaged with the inner wall of the card block 1, and finally the fixing buckle 11 is slid on the inner wall of the card slot 3 opened on the outer wall of the card block 1 to fix the elastic fixing plate 2, thereby completing the assembly of the hinge structure. The design of the elastic assembly and fixing of the hinge structure can be repeatedly precisely assembled, thereby achieving the effect of repeated precise assembly, thereby ensuring that the hinge structure of each pair of glasses has consistent assembly quality and performance, which helps to ensure the quality stability of the glasses. The hinge structure can not only realize the screwless rotating shaft hinge design, which is simple, firm, and not easy to loosen, thereby improving the stability and durability of the glasses, but also can achieve the effect of repeated precise assembly, thereby ensuring that the hinge structure of each pair of glasses has consistent assembly quality and performance, which helps to ensure the quality stability of the glasses.
