[0021] The present disclosure is further described in detail below in conjunction with the accompanying drawings and specific embodiments.
[0022] like Figures 1 to 6As shown, a pair of goggles comprises a half-frame frame 1, two temples 2 and a binocular integrated lens 3, the temples 2 are hinged to the frame 1, and the lens 3 is connected to the frame 1 via a quick-release and quick-install lens fixing structure.
[0023] The lens fixing structure involves a frame 1, a lens 3, two pressing blocks 4, two fixing members 5 and two elastic members 6. The lens 3 is clamped between the frame 1 and the pressing block 4. The frame 1 has a first limiting portion 11 and a second limiting portion 12. The second limiting portion 12 is located on the side of the first limiting portion 11 that is close to the pressing block 4. The fixing member 5 has a third limiting portion 51 and a connecting portion 52. The connecting portion 52 is located on the side of the third limiting portion 51 that is close to the pressing block 4. Two ends of the elastic member 6 respectively abut against the second limiting portion 12 and the third limiting portion 51. The first limiting portion 11 is used to cooperate with the third limiting portion 51 to limit the farthest distance that the fixing member 5 moves from the frame 1 to the pressing block 4. The connecting portion 52 is connected to the pressing block 4. The elastic member 6 is used to enable the fixing member 5 to apply a pulling force to the pressing block 4 to pull the pressing block 4 toward the frame 1 through the connecting portion 52, so that the pressing block 4 applies pressure to the lens 3, presses the lens 3 toward the frame 1, and fixes the lens 3.
[0024] By pulling the pressing block 4 away from the frame 1, the fixing of the lens 3 by the pressing block 4 can be loosened, and the lens 3 can be removed; first pull the pressing block 4, then insert the lens 3 between the pressing block 4 and the frame 1, release the pressing block 4, and the pressing block 4 presses the lens 3 on the frame 1 to fix the lens 3. The above-mentioned lens fixing structure can also be used in glasses of other structures, such as single-eye glasses or binocular glasses with separate lenses.
[0025] See also Figure 5 and 6 , a through hole is provided on the frame 1 corresponding to the fixing member 5, and the through hole is a three-level stepped hole, including a first-level hole, a second-level hole and a third-level hole with successively decreasing sizes, a first step is between the first-level hole and the second-level hole, and a second step is between the second-level hole and the third-level hole, and the first step and the second step are respectively used as the first limiting portion 11 and the second limiting portion 12. In other embodiments, the first limiting portion 11 and the second limiting portion 12 may also be other structures.
[0026] The fixing member 5 is a "T"-shaped structure, including a rod and a head. The radial dimension of the head is larger than that of the rod. The head serves as a third limiting portion 51. A groove is provided at the end of the rod away from the head. The groove serves as a connecting portion 52. A shaft 41 is fixedly provided on the pressing block 4. The shaft 41 is located in the groove. The radial dimension of the rod matches the third-level hole, and the radial dimension of the head matches the first-level hole. The elastic member 6 is a compression spring sleeved on the fixing member 5. The radial dimension of the elastic member 6 matches the second-level hole. A clearance groove 42 is provided on the pressing block 4 corresponding to the connecting portion 52. The clearance groove 42 is provided on the side of the pressing block 4 close to the frame 1, and the shaft 41 passes through the clearance groove 42.
[0027] The pressing block 4 is provided with a convex portion 43 on the side close to the frame 1, the lens 3 is provided with a plug hole 31 corresponding to the convex portion 43, and the frame 1 is provided with a slot 13 corresponding to the convex portion 43, and the convex portion 43 is inserted into the plug hole 31 and the slot 13 in sequence, thereby preventing the lens 3 and the pressing block 4 from moving relative to the frame 1. In other embodiments, the connection structure between the fixing member 5 and the pressing block 4 can also be other structures, and the elastic member 6 can also be other structures.
[0028] The pressing block 4 and the frame 1 are also provided with limiting step surfaces corresponding to the two ends of the lens 3, so as to prevent the lens 3 from moving relative to the frame 1 and improve the stability of the lens 3.
[0029] The above description is only a preferred embodiment of the present disclosure and is not intended to limit the present disclosure. It should be noted that any modification, equivalent replacement, improvement, etc. made by a person skilled in the art within the spirit and principle of the present disclosure after reading this specification should be included in the protection scope of the present disclosure.
