All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0021] Embodiment 1

[0022] Please refer to Figures 1 - 4 , a construction operation protection accessory shown in the figure, including goggles 101 and an elastic band 102 disposed on the side of the goggles 101 close to the face of the construction worker, and further including an adjustment component disposed on the goggles 101 for adjusting the elastic force of the elastic band 102;

[0023] The adjustment component includes an adjustment frame 201 fixedly connected to one side of the goggles 101. An adjustment rod 202 is rotatably connected in the adjustment frame 201. One end of the elastic band 102 is connected to the adjustment rod 202, and the other end of the elastic band 102 is connected to the side of the goggles 101 away from the adjustment frame 201. The adjustment frame 201 is provided with a driving component for driving the adjustment rod 202;

[0024] It should be noted here that: through the setting of the adjustment component, the elastic band 102 maintains a relatively comfortable squeezing force on the head of the construction worker, thereby improving the anti-detachment property of wearing the goggles 101 and being applicable to construction workers with different head sizes while improving the comfort of wearing the goggles 101.

[0025] Please refer to Figure 2 and Figure 3 , the driving component shown in the figure includes two symmetrically arranged fixing plates 301 fixedly connected to one side of the adjustment frame 201. The other ends of the two fixing plates 301 are fixedly connected with a fixing ring 302. A driving rod 303 is sleeved on the fixing ring 302. One end of the driving rod 303 close to the elastic band 102 is connected to the adjustment rod 202 through a connection component. The fixing ring 302 is provided with a limiting component for limiting the driving rod 303. The end of the driving rod 303 away from the adjustment frame 201 is fixedly connected with a rotating handle 304;

[0026] It should be noted here that: through the setting of the driving component, it is convenient to rotate the adjustment rod 202.

[0027] Please refer to Figure 2 and Figure 3, in the illustrated connection component, a connection hole 401 is provided in a section of the adjusting rod 202 close to the driving rod 303. A connecting plate 402 is slidably connected to the connection hole 401. A spline rod 403 is fixedly connected to a side of the connecting plate 402 close to the driving rod 303. A spline tube 404 is rotatably connected to a side of the adjusting frame 201 close to the fixed ring 302. The spline tube 404 is arranged to match the spline rod 403. One end of the driving rod 303 away from the rotating handle 304 penetrates through the spline tube 404 and is connected to the spline rod 403;

[0028] It should be noted here that: through the setting of the connection component, while the limit on the adjusting rod 202 is released, the spline tube 404 and the spline rod 403 remain connected. Thus, under the connection action of the spline tube 404 and the spline rod 403, it is convenient to rotate the adjusting rod 202.

[0029] Please refer to Figure 2 and Figure 3 , a spring 5 is fixedly connected to the bottom wall of the connection hole 401 in the illustration, and the other end of the spring 5 is connected to the connecting plate 402;

[0030] It should be noted here that: through the setting of the spring 5, after the step of the elastic band 102 is completed, the elastic force of the spring 5 is used to push the driving rod 303 to move away from the adjusting frame 201. Thus, the limit on the driving rod 303 is realized again by the limit component, and the adjusting rod 202 is further limited, thereby ensuring the use stability of the elastic band 102 after adjustment.

[0031] Working principle: When the goggles 101 are in use, first, the construction worker stretches the elastic band 102 according to the size of their own head shape, so that the elastic band 102 can be more conveniently put on the head. When stretching the elastic band 102, the rotating handle 304 is pushed to move close to the adjusting frame 201. At this time, the limit on the driving rod 303 is released, and further the limit on the adjusting rod 202 is released. At this time, the elastic band 102 can be stretched;

[0032] After the elastic band 102 is stretched to a certain length, the elastic band 102 can be sleeved on the head, and the goggles 101 can be worn at the eye position. After the position of the goggles 101 is placed, the rotating handle 304 is rotated to wind the excess elastic band 102 around the side wall of the adjusting rod 202, so that the elastic band 102 is close to the head of the construction worker. Thus, the elastic band 102 maintains a relatively comfortable pressing force on the head of the construction worker, thereby improving the anti - detachment property of wearing the goggles 101 and being applicable to construction workers with different head sizes, while improving the comfort of wearing the goggles 101.

A plurality of limiting holes 603 are formed in one side of the fixed ring 302 close to the limiting rod 602;

[0035] It should be noted here that: through the setting of the limiting component, by inserting the limiting rod 602 into the limiting hole 603, the limiting of the driving rod 303 is realized, and further the limiting of the adjusting rod 202 is realized.
