CONCRETE IMPLEMENTING METHOD

[0020] The technical scheme in the embodiments of the utility model will be clearly and completely described in combination with the drawings in the embodiments of the utility model, and obviously, the described embodiments only are a part of the embodiments of the utility model, not all the embodiments.

[0021] REFER Figures 1-4The utility model provides a protective glasses, including glasses frame 100, the bandage 101 and two layer glasses 102 are installed on glasses frame 100, fixedly installed on glasses frame 100 there is lens mounting frame 200, fixedly installed on the inner wall of lens mounting frame 200 there is rubber pad 203, and the replaceable lens 201 is arranged between lens mounting frame 200 and rubber pad 203, slidingly installed movable block 300 on glasses frame 100, rotatably installed transmission rod 301 on movable block 300, rotatably installed positioning pressure block 302 on the other end of transmission rod 301, and positioning pressure block 302 is in contact with replaceable lens 201, and the multilayer resin film piece 400 is arranged on two layer glasses 102, and the replaceable lens 201 position fixed effect of positioning pressure block 302 and rubber pad 203 cooperation is adopted, thereby realizing the replaceable operation of replaceable lens 201, and the replaceable lens 201 of appearing abrasion is quickly replaced with new replaceable lens 201, and the effect of prolonging the service life of protective glasses is realized.

[0022] When the replaceable lens 201 in the interior is damaged, movable block 300 can be moved, and the two ends of movable block 300 drive positioning pressure block 302 to move in movable hole 202 through transmission rod 301 and transmission shaft 307, so that the limiting and fixing of replaceable lens 201 by positioning pressure block 302 and rubber pad 203 are released, at this time, the replaceable lens 201 that is abraded can be replaced with a new replaceable lens 201, since movable block 300 will compress buffer spring 306 when moving, so that when movable block 300 is loosened, buffer spring 306 will pop movable block 300 back to the original position, realizing the re-fixing of the new replaceable lens 201, the replacement process is convenient and fast, and the effect of prolonging the service life of protective glasses is achieved.

[0023] The lens mounting frame 200 is provided with a movable hole 202, and the positioning pressure block 302 is slidably installed in the movable hole 202.

[0024] The glasses frame 100 is fixedly provided with a fixed block 303, the fixed block 303 is provided with a sliding hole 304, a sliding rod 305 is slidably installed in the sliding hole 304, and the sliding rod 305 is fixedly installed on the movable block 300. The movable block 300 is limited by the sliding hole 304 of the fixed block 303 and can only move within a fixed range.

[0025] Both ends of the transmission rod 301 are rotatably installed with transmission shafts 307, and the two transmission shafts 307 are fixedly installed on the movable block 300 and the positioning pressing block 302 respectively. The two ends of the movable block 300 drive the positioning pressing block 302 to move in the movable hole 202 through the transmission rod 301 and the transmission shaft 307, so as to release the limiting and fixing of the positioning pressing block 302 and the rubber pad 203 on the replaceable lens 201. At this time, the replaceable lens 201 that is worn out can be replaced with a new replaceable lens 201.

[0026] The sliding rod 305 is movably sleeved with a buffer spring 306, one end of the buffer spring 306 is fixedly installed on the fixed block 303, and the other end of the buffer spring 306 is fixedly installed on the movable block 300. When the movable block 300 is moved, the buffer spring 306 is compressed, so that when the movable block 300 is loosened, the buffer spring 306 will pop the movable block 300 back to the original position, realizing the re-fixing of the new replaceable lens 201, the replacement process is convenient and fast, and the service life of the protective glasses is prolonged.

[0027] A plurality of the resin film pieces 400 are fixedly installed with tear strips 401, the specifications of the resin film pieces 400 gradually decrease, and epoxy resin is arranged between the resin film pieces 400. When the user's second layer of glasses 102 has too much dust attached, the outer resin film piece 400 is directly torn off using the tear strip 401, so as to achieve quick and clear vision, and the resin film pieces 400 are connected using resin, the stable bonding effect can avoid accidental falling of the resin film pieces 400, and does not affect the user's tearing.

[0028] Working principle:

[0029] In use of the device, the user needs to wear the glasses frame 100 on the head by using the bandage 101, and then combine the two layers of glasses 102, when the user's two layers of glasses 102 are too much attached with dust, directly tear off the outer resin film sheet 400 by using the tear strip 401, so as to achieve the clear vision, at the same time, the resin film sheet 400 is connected by using the resin, the adhesive effect is stable, the accidental falling of the resin film sheet 400 can be avoided, and the user can tear off, when the inner replaceable lens 201 is damaged, the movable block 300 can be moved, the two ends of the movable block 300 drive the positioning pressing block 302 to move in the movable hole 202 through the transmission rod 301 and the transmission shaft 307, so as to release the limiting and fixing of the replaceable lens 201 by the positioning pressing block 302 and the rubber pad 203, at this time, the replaceable lens 201 that is worn can be replaced by the new replaceable lens 201, since the movable block 300 will compress the buffer spring 306 when moving, the buffer spring 306 will pop back the movable block 300 to the original position when the movable block 300 is loosened, the new replaceable lens 201 is re-fixed, the replacement process is convenient and fast, and the service life of the protective glasses is prolonged.

[0030] The above is only the preferred specific implementation of the present application, but the protection scope of the present application is not limited to this, any skilled person in the art can make equivalent replacement or change according to the technical scheme and the inventive concept of the present application within the technical range disclosed by the present application, which should be covered in the protection scope of the present application.
