Both sides of the added rotating frame can be fixed to both sides of the original rotating frame by rotating elements (round nails, etc.). Β· As shown in Figure 3, a frame panel [8] that fits the front upper edge of the helmet shell and a light-colored lens [3] are used; the frame panel is provided with a corresponding upper edge of the helmet shell.

[New content] This creation is to provide another implementation of the above prior art; this creation uses the combination of colored lenses to deepen the color, the shading effect will strengthen the principle, the transparency (visual transmittance) • the same or similar At least two colored lenses (each color lens, dyed lens, color film lens, sunshade lens, etc.) are fixed on the fixed base of the helmet according to the overlapping manner, so that the user can "gradually" according to the weather conditions. The mode adjusts the required shading strength; the above-mentioned helmet fixing base can be: helmet shell, helmet cap, helmet frame, helmet lens, .... The difference between this creation and the above-mentioned prior art items 1, 2, and 3: Pre-technical: a. The contrast between the two lenses is obvious, which can be distinguished by the naked eye, that is, the transparency of the two lenses (visual transmittance) Larger. b. The position of the two lenses must be shallow before and after, in order to have the essence of adjusting the shading for 8 M317181. c•Because of the large difference in transparency between the two lenses, the difference between light and dark is large when the single or double film is used in combination. The color of the two lenses is the same or similar, and it is difficult to distinguish with the naked eye, that is, the transparency (visual transmittance) of the two lenses is the same or similar. b. The two lenses have the same or similar shades, so there is no problem with the front and rear positions. C• The transparency of the two lenses is similar or similar, so when used in single or double-chip phase, it provides a more average “gradual” shading effect. Advantages of this creation ··· This creation provides a more average “gradual” shading effect, allowing users to adjust the appropriate transparency and increase vehicle safety. 2. The color process of lens production can be singular, that is to say, one color can be adjusted. Example description: 1. As shown in Figure 4, use the helmet shell (1) with two colored lenses [9, 10] of the same or similar transparency; the two sides of the helmet shell are provided with screw holes to make the two lenses available. The left and right screws [2] are fixed on the helmet and have the function of opening and closing the upper and lower rotations; thereby, when the sunlight is strong during the day, the two lenses [9, 1] can be closed downward. Make the opacity stronger and block the glare; when the evening or the weather is dark, the lens [1()] can be lifted up, the lens [9] is downward, so that the lens can reduce the opacity of the bribe; 'The two lenses [9, 10] can be lifted up to improve the night vision. 2. As shown in Figure 5, 'one-hard hat (four) [5] two colored lenses with the same or similar transparency 9 M317181 [9,10]; the helmet cap is provided with a corresponding upper edge fixing element of the helmet shell (fixed Fastening element of the buckle and screw hole [6] (fixing buckle, hole----), so that the helmet cap can be fixed on the upper edge of the helmet shell; the two sides of the two lenses [9, 10] can be rotated The component [7] (round nail, screw, etc.) is fixed to both sides of the helmet cap, so that it has the function of opening and closing the upper and lower rotation; the method of use is the same as the first item of the above description. 3. As shown in Figure 6, a helmet lens panel [8] is used with two colored lenses [9' 10] of the same or similar transparency; the helmet frame is provided with a corresponding upper edge of the helmet shell. Fixing element [6] (fixed, hole----), so that the helmet frame can be fixed to the upper edge of the helmet shell; the two lenses [9, 10] Both sides can be fixed on both sides of the helmet frame by using rotating elements [7] (round nails, screws, etc.), so that they have the function of opening and closing the upper and lower rotation; The example description is the same as item 1. 4. As shown in Figure 7, use a safety cap 檐 [5] (or helmet shell or helmet frame), two colored lenses with the same or similar transparency [9, 10]; first lens [9] Fixed on the helmet cap '' and then the lens [10] is fixed to the lens [9] by using the snap element [11, 12] or the rotating component or the like; that is, fixing the front lens [1] In the way of the rear lens [9]; when the daytime sunlight is strong, the two lenses [9, 1〇] can be closed downwards to enhance the opacity and block the glare; when the evening or the weather is dark, The lens [1〇] can be removed or moved down or lifted up to reduce the transparency and reduce the opacity; when the night light is dim, both lenses [9, 10] can be lifted up to improve the night vision. Attached to the main 1 · This creation is to use the same or similar transparency (visual transmittance) of at least two colored lenses fixed on the fixed base of the helmet; the word "same" is the confirmation statement, but the M317181 is in production It is often the same as the transparency of the two lenses due to temperature changes, machine operation, lens thickness, quality control, etc., which leads to controversy in the data; the meaning of "similar" is *light statement, which refers to What is the miscellaneous? It is also very controversial; therefore, this creation must have a transparency data to define its scope. This creation uses a range that is not immediately distinguishable by the average human eye as the "same and similar" range, which is about the difference in transparency between the two lenses. Within the range of 25%; the range of transparency difference between the two lenses exceeds 25%. The contrast between the shades of the shades is obvious. Generally, the average human eye can immediately divide the notes. 2: The mirror (4) is not limited to the above examples. The manner of explanation can be implemented by referring to the "prior art". Note 3: The fixed base of the helmet related to the present invention may be an assembly, which may be a combination of a helmet shell and a helmet cap, a combination of a helmet shell and a helmet frame, etc. Therefore, at least two lenses of the present invention can be respectively fixed on the components of the assembly, for example, one of the two lenses can be fixed on the helmet shell, and the other lens can be fixed on the helmet cap. Attached to $Main 4 · When the lens is two >; or three or more, the lens at the last side can be a transparent lens, so that when the instrument is dimly lit, the user can use a transparent lens. [Embodiment] The lens structure of a safety helmet of the present invention is improved by using a helmet to fix the base and at least two colored lenses fixed on the base (color lenses, dyed lenses, color film lenses, sunshade lenses... .. etc.); The creation of the present is: · The at least two colored mirror-like fineness is compared with each other at a 25% _; thereby, the safety _ wire base is formed with at least two 11 M317181 colored lenses of the same or similar transparency, Adjust the required shading intensity in a gradual manner to achieve visual weather conditions.
