DETAILED DESCRIPTION

[0022] The exemplary embodiments of the disclosure will be described clearly and completely in combination with the appended drawings in order to clarify the purposes and advantages of the present disclosure. Apparently the to-be-described exemplary embodiments are only part of the embodiments of the disclosure, and not a complete set of the embodiments. Other embodiments obtained by one skilled in the related art based on the embodiments described in this present disclosure without any creative effort will be included within the protection scope of this disclosure.

[0023] Referring to FIGS. 1-5, the exemplary embodiments employ the following technical solutions. The embodiments of this disclosure are illustrated below in further detail by referring to Figures.

[0024] FIG. 1 is a structure diagram of a novel protective visor 100 according to one embodiment of this disclosure. The novel protective visor 100 includes a headband (5), a face shield (1), protective goggles (6), a light shading screen (4), a light grid (8) and a housing (2).

[0025] The above-described light refraction and transmission device is a light aperture that is processed to have a special shape, e.g., the serrated lattice shutter structure shown as reference sign (8) in FIG. 2, and located at the front and upper end portion of the housing (2). The light aperture has the light shading screen (4) disposed at the outer side of the light aperture. The light shading screen (4) is made of a special material such as polycarbonate, and is dark color and translucent, and thereby effectively shields against harmful glares, ultraviolet (UV) rays, blue rays, etc.

[0026] FIG. 2 is a structural diagram 200 of a light refraction and transmission device and protective goggles of the novel protective visor 100 according to one embodiment of the disclosure. Referring to FIG. 2, the protective goggles (6) have an adjustment guide rail (9) disposed on both sides of the goggles (6) respectively. The upper end of the protective goggles (6) is connected to the light shading screen (4) and the light grid (8) via an adjustment slider (3). After assembly, the adjustment slider (3) and the protective goggles (6) have fixed relative position. In the middle portion of the light shading screen (4), a sliding region for the adjustment slider is set. When the adjustment slider (3) is sliding up and down the sliding region in the middle of the light shading screen, the protective goggles can be driven to move up and down, and thus the adjustment of the position of the protective goggles can be achieved.

[0027] After an operator wears the protective visor correctly according to the wearing method of the traditional head-mounted visor, the face shield (1) can be adjusted to an appropriate angle. The protective goggles (6) can be moved up and down to desired positions according to different needs under different operation environments. When the protective goggles is not needed, the protective goggles can be placed to the top of the face shield by adjusting the adjustment slider (3) of the light refraction and transmission device, thus avoiding to affect the operation vision. In addition, by placing the protective goggles (6) to the top position, the protective goggles (6) can effectively absorb the light passing through the light refraction and transmission device and thus effectively prevent the incidence of the UV rays.

[0028] FIG. 3 is a diagram 300 of an adjustment clip of the novel protective visor according to one embodiment of the disclosure. Referring to FIG. 3, the adjustment clip (7) is disposed along with the adjustment guide rail (9) on either or both sides of the protective goggles (6). The adjustment clip (7) is used to fix the relative position of the protective goggles. For example, when the adjustment slider (3) slides up and down, the protective goggles is driven to move up and down accordingly and once a desired position is determined by the operator, the adjustment clip (7) can be used to fasten the protective goggles to the desired position.

[0029] The protective goggles and their gear device (e.g., the adjustment guide rail, the adjustment slider, and the adjustment clip) in the present disclosure can be equipped optionally according to different users' desires. For example, the protective visor can be made without the protective goggles and the gear device by changing the design of the light shading screen.

[0030] FIG. 4 is a diagram 400 of a face shield of the novel protective visor without the protective goggles and their gear device according to one embodiment of the disclosure. FIG. 5 is a diagram 500 of a ventilation hole (10) of the novel protective visor according to one embodiment of the disclosure. Referring to FIGS. 4 and 5, the sliding structure may be removed from the light shading screen in FIG. 1 and the shape of the light shading screen (4) may be changed to a curved model structure, as shown in FIG. 4. In addition, the ventilation hole (10) may be prepared for the housing, as shown in FIGS. 4 and 5.
