Description of the Invention: [Technical Field of the Invention] The present invention relates to a safety helmet frame structure for a double lens. [Prior Art] 1. There is a helmet on the market. As shown in Figure 8, the helmet [14] is equipped with a double lens, a dark lens [12] is in front, and a light lens [13] is behind. The holes of the same position are provided on both sides of each lens. Therefore, after the two lenses are stacked, the holes are also overlapped by air, and then the left and right screws [11] are passed through the two sides of the lens. The holes can be used to lock the two lenses to the sides of the helmet; thus, the user can select the appropriate lens to use depending on the weather conditions. 2. I have previously applied for the "double lens hard hat cap structure", application number: 95116299; its content is as shown in Figure 9, using a cap Zhan [19] and a light-colored lens [18]; The cap is provided with a fixing buckle corresponding to the front upper edge of the hard hat [10], and a hole corresponding to the screw hole of the front upper edge of the female full cap shell, so that the cap can be fixed on the front of the helmet shell. The light-colored lens [18] can be fixed on the brim by using a rotating member [15] (round nail, etc.) or a lens fixing member; the invention is mainly applied to the brim [19] and no dark color is added. The lens [17]' is located in front of the light-colored lens [18], and the dark lens is fixed on the brim by: a. The two sides of the dark lens [17] can each use the rotating element [16] (circle) Nail····etc.) is fixed on both sides of the hat Zhan [19], as shown in Figure 9. b. Both sides of the dark lens and the sides of the light lens can share the rotating elements (round nails ... 5 1294770 v, etc.) fixed on both sides of the cap. C. Both sides of the dark lens may be fixed to both sides of the light-colored lens by means of rotating elements (round nails, etc.). Thereby, a double lens of a front dark color and a rear light color can be formed on the brim. 3. There is a kind of safety helmet on the market. As shown in Figure 10, the frame is composed of a frame panel (1) and a rotating age [2]. The panel is equipped with a corresponding helmet. The upper edge of the mosquito nine 111 set & [4], the age panel can be set to the upper edge of the helmet shell; the two sides of the rotating frame [2] are fixed by the rotating element [5] (round nail) The two sides of the frame [1] enable the rotating frame to be rotated up and down on the frame of the frame. When the lens [9] is fixed on the rotating frame, the upper function of the lens can be formed; the rotating mirror The frame [2] is provided with a lens fixing member [7] (stitching member or fixing button member...) combined with the lens, and the fixing button member is used to disassemble the lens on the rotating frame; the rotating frame can be used as In addition to the joint bracket, the external strength and the fixed strength of the lens can be improved. • Disadvantages: Because there is only one lens, the consumer can only choose one lens, choose light lens or dark lens; light lens can be seen clearly at night, but it feels very strong during the daytime. It is glaring; although the dark lens can withstand the strong sunlight during the day, it will hinder the driving sight at night. SUMMARY OF THE INVENTION A double-lens safety helmet frame structure of the present invention has the disadvantage that the single lens of the conventional frame of the prior art item 3 is not suitable for daytime or nighttime use; the present invention mainly designs the frame panel. A lens can be added to make the frame of the frame have a color tone of 12,947,700. The two lenses are obvious, so that the user can select the function of shading and non-shading depending on the weather conditions. The difference between the present invention and the above prior art items 1 and 2 is as follows: 1. The body is different: Prior art 1: as shown in FIG. 8, it is set on the helmet [14] to set the two lenses with the contrast of shades and shades [12, 13], so the prior art is based on the helmet. Prior Art 2: As shown in Fig. 9, it is set on the brim [19] to set the two lenses [17, 18] with contrasting shades, so the prior art is based on the cap. According to the present invention, the present invention is based on the lens panel [丨], which is provided with two lenses [8, 9] having a lighter shade and contrast. Therefore, the present invention is a frame panel. 2. Different fixing methods: Prior art 1: As shown in Figure 8, the two lenses [12, 13] are directly locked to the outer casing of the helmet [14] by screws (1). Prior Art 2: As shown in Figure 9, the two lenses [17, 18] are fixed on the brim [19], and then the cap is fixed on the outer casing of the helmet [1]; in other words, the two lenses are fixed to the safety through the cap. On the cap shell. The invention: the two lenses [8, 9] of the invention are mounted on the frame of the frame [丨], and then the frame of the frame is fixed on the outer casing of the helmet [10]; for t, the two lenses are through the frame The panel is attached to the helmet shell. 1294770 ♦ 孓 Different types of helmets: Prior art 1: As shown in Figure 8 + Gan 6 No. Female full cap type is a fixed component (screw hole) set δ ten on both sides of the shell of the helmet. The present invention. The helmet of the present invention is a canopy element (10) or a screw hole designed to be a hard hat on the upper front edge of the outer casing. The difference between the Μ and the frame _ : The hat panel of the hat county is solid and can be read * the upper edge of the whole shell, but the two are not related to the object; Fixing "body", that is, fixing the two sides of the lens to the "fixed mediator" by the rotating element _ 'The lens can be rotated up and down on the "fixed mediator" to form the upper gongs, although The peripherals have a fixed edge or a screw hole. The helmet must be equipped with a mirror that can be mounted. (4) 'The upper edge of the helmet shell is covered with a sunshade and rain cap. It is a ready-to-use "fixed mediator". As long as the two sides of the lens are fixed on both sides of the cap layer by using the rotating component, the upper and lower turns of the upper structure can be formed to achieve the dual-use effect; however, the helmet does not have to be equipped with a cap. The upper edge of the helmet shell is provided with a fixed or screw hole, which is to make the user selectable; therefore, the frame panel is a "fixed mediator" designed for the upper lens when the user does not want to wear a cap. "The best difference between the brim and the frame panel" The cap lens of both the cap and the frame panel is removed, and the cap is still a sunshade cap, and the frame panel is only an ineffective panel that is fixed to the upper edge of the helmet, so the frame panel It is an object designed purely for fixed lenses; therefore, the structure of the upper eyelid formed by the brim is different from the structure of the upper lens formed by the frame. 1294770 Advantages of the invention: The manufacturer of the helmet of this type of duck can be seen in the weather conditions.
