The inner wall of the half-toothed sleeve 316 is fixedly connected with an arc plate 317, and the front side of the arc plate 317 is fixedly connected with a connecting plate 318. The front side of the connecting plate 318 is provided with a mounting slot 319. The center points of the left and right ends of the half-toothed sleeve 316 are fixedly connected with a rotating rod 310. The outer wall of the rotating rod 310 is movably connected to the inner wall of the support sleeve 313. The disassembly component 32 includes a sunshade transparent plate 321. By turning the plum blossom knob 314, the worm 315 rotates, thereby driving the half-toothed sleeve 316 to rotate. Since the half-toothed sleeve 316 is fixedly connected to the arc plate 317, the arc plate 317 and the connecting plate 318 rotate accordingly, and the rotating rod 310 rotates on the inner wall of the support sleeve 313, realizing The sunshade transparent plate 321 is adjusted up and down, and the front, left and right sides of the outer wall of the sunshade transparent plate 321 are movably connected with concave grooves 322, and the rear sides of the left and right concave grooves 322 are fixedly connected to the front side of the connecting plate 318, and the left and right sides of the front concave groove 322 are fixedly connected with blocks 323, and the outer walls of the two blocks 323 are movably connected to the front sides of the inner walls of the left and right concave grooves 322. A circular through hole 324 is provided on the top of the block 323 and passes through to the bottom. An internal threaded hole 325 is provided on the top front side of the left and right concave grooves 322 and passes through to the inside. The inner wall of the internal threaded hole 325 is threadedly connected with a threaded column 326, and the bottom of the threaded column 326 is fixedly connected with a rod 327. The outer wall is movably connected to the inner wall of the circular through hole 324, and the top of the threaded column 326 is fixedly connected with an anti-slip knob 328. When the sunshade transparent plate 321 needs to be disassembled, the anti-slip knob 328 can be rotated so that the anti-slip knob 328 drives the threaded column 326 to rotate on the inner wall of the internal threaded hole 325, thereby pulling the insertion rod 327 out of the circular through hole 324 of the block 323, and then pulling out the concave groove 322 in front, and then pulling the sunshade transparent plate 321 outward, thereby realizing the rapid disassembly and replacement of the sunshade transparent plate 321. The position of the sunshade transparent plate 321 can be adjusted according to actual needs to adapt to different lighting conditions to ensure the best sun protection effect during outdoor activities.

[0029] See also Figure 6-7The sun protection structure 2 4 includes a sunshade cloth 41, and two fixed sleeves 42 are fixedly connected to the middle position of the top of the sunshade cloth 41. The inner wall of the fixed sleeve 42 is movably connected to a hanging rod 43, and the front end of the hanging rod 43 is fixedly connected to the outer wall of the safety helmet 1. The ends of the top of the sunshade cloth 41 away from each other are fixedly connected to a rectangular frame 44, and the inner wall of the rectangular frame 44 is movably connected to a limiting component 45. The limiting component 45 includes a fixing plate 451, and the front side of the fixing plate 451 is fixedly connected to a connecting plate 2 452. A limiting slot 453 is provided on the front upper side of the connecting plate 2 452. The left and right sides above the front side of the fixing plate 451 are fixedly connected to limiting columns 454. The outer wall front side of the limiting column 454 is covered with a spring 455. The outer wall rear side of the limiting column 454 is movably connected to a movable sleeve 456. The two movable sleeves 456 are fixedly connected to a concave plate 457 on the side close to each other. The front side of the concave plate 457 is fixedly connected to a connecting plate 3 458. The bottom is fixedly connected with an extension plate 459, and the rear side of the extension plate 1 459 is fixedly connected with the extension plate 2 450. The rear lower part of the extension plate 2 450 is fixedly connected with a rectangular plug 4501. The outer wall of the rectangular plug 4501 is movably connected to the inner wall of the limiting slot 453. The rear side of the fixed plate 451 is fixedly connected to the outer wall of the safety helmet 1. By pulling the concave plate 457 outward, the movable sleeve 456 is driven to slide on the outer wall of the limiting column 454 and squeeze the spring 455, thereby driving the connecting plate 3 458, the extension plate 1 459, the extension plate 2 450, and the rectangular plug 4501 to move, so that the rectangular plug 4501 is pulled out of the limiting slot 453, and then the rectangular frame 44 is moved out of the outer wall of the connecting plate 2 452, and the fixed sleeve 42 is moved out of the outer wall of the hanging rod 43, thereby releasing the fixed state of the sunshade cloth 41, enhancing the sun protection effect of outdoor workers, and facilitating the cleaning and replacement of the sunshade cloth 41.

[0030] When the visor 321 is in the upright position, the worm gear 315 is rotated to rotate, thereby driving the half gear sleeve 316 to rotate. Since the half gear sleeve 316 is fixedly connected to the curved plate 317, the curved plate 317 and the connecting plate 318 rotate accordingly, and the rotating rod 310 rotates on the inner wall of the supporting sleeve 313 to achieve the up and down adjustment of the transparent sunshade plate 321. When the transparent sunshade plate 321 needs to be removed, the anti-slip knob 328 can be rotated to make the anti-slip knob 328 drive the threaded column 326 to rotate on the inner wall of the internal threaded hole 325, thereby making the insertion rod 327 move out of the circular through hole 324 of the stopper 323, and then the concave groove 322 in the front is pulled out, and the transparent sunshade plate 321 is pulled outward, thereby achieving the quick removal and replacement of the transparent sunshade plate 321. The position of the transparent sunshade plate 321 can be adjusted according to actual needs to adapt to different lighting conditions, ensuring the best sun protection effect during outdoor activities.

[0031] By pulling the concave plate 457 outward, the movable sleeve 456 is driven to slide on the outer wall of the limiting column 454, and the spring 455 is squeezed, thereby driving the connecting plate three 458, the extension plate one 459, the extension plate two 450, and the rectangular plug block 4501 to move, so that the rectangular plug block 4501 is pulled out from the limiting slot 453, and then the rectangular frame 44 is moved out of the outer wall of the connecting plate two 452, and the fixed sleeve 42 is moved out of the outer wall of the hanging rod 43, thereby releasing the fixed state of the sunshade cloth 41, enhancing the sun protection effect of outdoor workers, and facilitating the cleaning and replacement of the sunshade cloth 41.

[0032] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
