DETAILED DESCRIPTION

[0015] The following is a specific embodiment of the present application combined with the drawings, which further describes the technical scheme of the present application, but the present application is not limited to these embodiments.

[0016] As Figures 1-4As shown, the rotating positioning structure of the glasses leg includes an elastic piece 2 on the glasses leg body 1, a connecting block 3, and a mounting block 5 on the glasses frame 4. The connecting block 3 is provided with a plurality of arc-shaped hooks 32. The elastic piece 2 includes a fixed part 21 and an elastic part 22. The fixed part 21 is fixed in the mounting groove 11, and the elastic part 22 is arranged obliquely relative to the fixed part 21 and has an active gap between the elastic part 22 and the groove bottom of the mounting groove 11. The elastic part 22 is provided with a plurality of active holes 24, and the mounting block 5 is provided with a plurality of connecting holes 51. The end of the arc-shaped hook 32 penetrates through the active hole 24 and is embedded in the connecting hole 51, and the mounting block 5 and the arc-shaped hook 32 can rotate relative to each other. The glasses frame 4 is connected with the glasses leg body 1 through the arc-shaped hook 32 and the connecting hole 51 on the mounting block 5. When it is needed to separate the glasses frame 4 and the glasses leg body 1, the arc-shaped hook 21 is directly separated from the connecting hole 51, and the glasses frame 4 and the glasses leg body 1 are separated simply and conveniently.

[0017] In the above technical solution, the end of the mounting block 5 forms an abutting part 52. When the glasses leg body 1 is in the open state, the elastic part 22 is in a relaxed oblique state, as shown in Figure 2 When the glasses leg body 1 rotates from the open state to the folded state, the arc-shaped hook 32 and the elastic part 22 rotate relative to the mounting block 5, the abutting part 52 extrudes the elastic part 22, and the elastic part 22 moves in the direction of the glasses leg body 1; when the elastic part 22 rotates to contact the groove bottom of the mounting groove 11, the glasses leg body 1 is in the folded state, as shown in Figure 3 .

[0018] The arc-shaped hook 32 is embedded in the connecting hole 51 on the mounting block 5 to realize the rotating connection between the glasses frame 4 and the glasses leg body 1, and the friction of the above rotating connection mode is greater than that of the common hinge mode in the prior art, so that the glasses leg body 1 needs to exert an external force to rotate relative to the glasses frame 4, preventing the glasses leg body 1 from rotating accidentally and ensuring the convenience of use. At the same time, the obliquely arranged elastic part 22 positions the glasses leg body 1 in the open state, and when the glasses leg body 1 rotates from the open state to the folded state, force must be applied to resist the elasticity of the elastic part 22, thereby further preventing the glasses leg body 1 from rotating automatically in the open state and ensuring the comfort of the user's wearing experience. When the glasses leg body 1 continues to rotate outward in the open state by applying force, the mounting block 5 moves the elastic part 22 in the direction of the glasses leg body 1 until the elastic part 22 contacts the groove bottom of the mounting groove 11; the gap between the elastic part 22 and the mounting groove 11 enables the glasses leg body 1 to continue to rotate outward in the open state, facilitating people to open the glasses to a larger angle when wearing the glasses, and facilitating wearing; at the same time, the opening degree of the glasses leg body 1 is limited, preventing the glasses leg body 1 from being opened too much and affecting use.

[0019] The connecting block 3 is further provided with a clamping hook 31, and the fixing portion 21 is provided with a plurality of fixing holes 23, the clamping hook 31 passes through the fixing hole 23 and is clamped and installed on the temple body 1. When the elastic member 2 needs to be disassembled, the arc-shaped hook 21 is separated from the movable hole 24, and the clamping hook 31 is separated from the fixing hole 23, so that the elastic member 2 and the temple body 1 are conveniently disassembled, and the elastic member 2 is conveniently repaired and replaced.

[0020] In the above technical solution, the temple body 1 is provided with a plurality of insertion grooves which are in communication with the installation groove 11. The plurality of connecting blocks 3 are parallel to each other, and the connecting block 3 comprises an insertion plate 33 which is embedded in the insertion groove, so that the connecting block 3 is fixed on the temple body 1. The number of the connecting block 3 can be two, that is, two arc-shaped hooks 32, two clamping hooks 31 and two insertion plates 33, as shown in Figure 2 、 Figure 3 As shown in Figure 4 , the number of the connecting block 3 can also be three, that is, three arc-shaped hooks 32, three clamping hooks 31 and three insertion plates 33, as shown in

[0021] The arc-shaped hook 32 of the rotating positioning structure of the glasses temple is embedded in the connecting hole 51 of the mounting block 5, so as to realize the rotating connection between the frame 4 and the temple body 1, and the friction of the above rotating connection mode is large, so that the temple body 1 needs to exert an external force to rotate relative to the frame 4, thereby preventing the temple body 1 from rotating accidentally. At the same time, the elastic portion 22 arranged obliquely positions the temple body 1 in the open state, and when the temple body 1 rotates from the open state to the folded state, a force must be exerted to resist the elasticity of the elastic portion 22, thereby further preventing the temple body 1 from rotating automatically in the open state, and ensuring the comfort of the user's wearing experience. The gap between the elastic portion 22 and the installation groove 11 enables the temple body 1 to continue to rotate outward after being opened, which is convenient for people to wear glasses at a larger angle, and is convenient for wearing. At the same time, the opening degree of the temple body 1 is limited, so as to prevent the temple body 1 from being opened too much and affecting the use. When the elastic member 2 needs to be disassembled, the arc-shaped hook 21 is separated from the movable hole 24, and the clamping hook 31 is separated from the fixing hole 23, so that the elastic member 2 and the temple body 1 are conveniently disassembled, and the elastic member 2 is conveniently repaired and replaced.
