[0030] Referring to Figures 1 to 6 , the outside of the two sliding rods 4 is fixedly connected with fixed ring 5, in the moving process of the sliding rod 4, the fixed ring 5 stably slides along the track in the inside of the mirror frame 1, and is connected with one end of the spring 6, and the elastic force of the spring 6 is transmitted, so as to control the position and state of the sliding rod 4. The outside of the fixed ring 5 is slidably connected in the inside of the mirror frame 1, the outside of the two sliding rods 4 is sleeved with the spring 6, and the fixed ring 5 is used to limit the displacement range of the sliding rod 4, and cooperates with the spring 6. One end of the spring 6 is fixedly connected at the bottom of the fixed ring 5, the other end of the spring 6 is fixedly connected in the inside of the mirror frame 1, the bottom of the two sliding rods 4 is fixedly connected with pull plate 7, and the pull plate 7 is the component directly interacted by the user and the quick release mechanism. For example Figure 5As shown, the inner part of the two guide blocks 3 is provided with a clamping groove 8, when pulling the pull plate 7 to drive the sliding rod 4 to move, the spring 6 will be compressed, storing elastic potential energy; when the external force is released, the spring 6 restores the fixed ring 5 and the sliding rod 4 to the original position by its own elastic restoring force, so that the sliding rod 4 re-slides into the inner part of the clamping groove 8, completing the fixation of the lens 2.

[0031] Referring to Figures 2 to 4 , the outer part of the sliding rod 4 is slidingly connected in the inner part of the clamping groove 8, when the sliding rod 4 slides into the inner part of the clamping groove 8, through the limiting action of the clamping groove 8, the fixation of the lens 2 is realized, preventing the lens 2 from shifting or falling off during normal use. The inner part of the rear side of the frame 1 is provided with two guide grooves 9, which provide accurate sliding guidance for the guide blocks 3, so that the lens 2 can move stably along the guide grooves 9 during installation and disassembly, ensuring that the lens 2 can be accurately installed to the predetermined position inside the frame 1, and ensuring the relative position accuracy between the lens 2 and the frame 1, which is beneficial to improve the overall performance and protection effect of the goggles. The outer part of the lens 2 is provided with a sealing groove 10, and the rear side of the frame 1 is fixedly connected with a close pad 11, the inner part of the close pad 11 is provided with two guide grooves 9 on the left and right sides, and the outer part of the guide block 3 is slidingly connected in the inner part of the guide groove 9.

[0032] Referring to Figure 2 , Figure 3 and Figure 5 , the outer part of the lens 2 is slidingly connected in the inner part of the close pad 11, the material of the close pad 11 is silica gel material, the surface of the close pad 11 contacts with the human face, and its shape is designed according to the human face contour, which can closely fit on the facial skin, reducing the gap when wearing, improving the sealing performance and comfort of the goggles. The inner part of the frame 1 is fixedly connected with a sealing strip 19, when the lens 2 is installed in the inner part of the frame 1, the sealing strip 19 can be closely embedded in the sealing groove 10, forming a continuous sealing interface, effectively preventing dust, water vapor and other impurities from entering the inner part of the frame 1, protecting the optical performance of the lens 2, prolonging the service life of the lens 2, and ensuring the cleanliness and dryness of the inner part of the goggles, providing a clear view for the user.

[0033] Referring to Figure 1 , Figure 2 and Figure 6The fixing mechanism comprises two connecting blocks 13, the front sides of the two connecting blocks 13 are fixedly connected to the rear sides of the two connecting plates 12 respectively, the rear sides of the two connecting blocks 13 are fixedly connected with connecting bands 14, the connecting blocks 13 tightly connect the connecting plates 12 and the connecting bands 14 together, and the fixing function of the goggles on the head of the user can be effectively realized. The material of the connecting bands 14 is rubber material, the connecting bands 14 have a certain pre-tightening force in the normal state, and the goggles can be stably worn on the head. When the head size of the user is large or small, the connecting bands 14 can be stretched or contracted through the elastic deformation of the connecting bands 14, so that the appropriate wearing tightness can be always maintained;

[0034] The right side of one of the connecting bands 14 is fixedly connected with a female buckle 15, the left side of the other connecting band 14 is fixedly connected with a male buckle 16, the outer part of the male buckle 16 is slidably connected in the inner part of the female buckle 15, the inner structure of the female buckle 15 is designed with a groove matched with the male buckle 16, and the outer shape of the male buckle 16 can be smoothly slid into the inner part of the female buckle 15 and fixedly clamped. The front side of the female buckle 15 is fixedly connected with a gasket one 17, and the front side of the male buckle 16 is fixedly connected with a gasket two 18. The material of the gasket one 17 and the gasket two 18 is memory cotton material, the gasket one 17 and the gasket two 18 can also contact the facial skin during wearing of the goggles, the comfort of wearing is further improved, the goggles can better adapt to the head shape of the staff, and the compression feeling caused by long-time wearing on the head and face is reduced.

[0035] Working principle: when the lens 2 needs to be quickly installed and disassembled, the pull plate 7 is pulled, the slide rod 4 is driven to displace through the pull plate 7, at this time, the fixing ring 5 slides in the inner part of the lens frame 1, and the spring 6 is compressed, so that the slide rod 4 is separated from the inner part of the guide block 3, at this time, the lens 2 can be slid out of the inner part of the lens frame 1, so that the lens 2 can be quickly disassembled. When installing, the guide block 3 is aligned to the inner part of the guide groove 9 and slid to the inner part, until the sealing strip 19 enters the inner part of the sealing groove 10, so that dust and water vapor can be prevented from entering the inner part of the lens frame 1. Then, the slide rod 4 is reset by the rebound force of the spring 6, and then it can be slid into the clamping groove 8, so that the fixing of the guide block 3 can be completed, and the installation of the lens 2 can be completed. In the use process, the elastic properties of the connecting bands 14 can adapt to different staff with different head circumferences, the stability of the goggles can be ensured by the female buckle 15 and the male buckle 16, and the head shape of the staff can be better adapted by the gasket one 17 and the gasket two 18, so that the comfort of wearing can be ensured.

[0036] Finally, it should be noted that: the above only for the preferred embodiments of the present application, and is not intended to limit the present application, although the foregoing embodiments of the present application has been described in detail, for the skilled in the art, it still can be modified, or for part of the technical features of the equivalent replacement, the spirit and principles of the present application, made any modification, equivalent replacement, improvement, etc., should be included within the scope of the present application.
