New description: [New technical field] This creation department is about a safety helmet. [Prior Art] The female full cap can be worn by the user when riding the locomotive, and the user can wear a transparent lens on the front side of the helmet for blocking the strong wind. In addition, in order to avoid the daytime sunlight The glare causes the user to dazzle, and the lens is also set as a sunglass lens, which can block strong winds and excessively strong light at the same time. However, when the helmet is used at night, it is easy to block the light and cause poor line of sight, forming a safety. The hidden worry. [New Content] The main purpose of this creation is to provide a helmet that helps block light when the ambient light is too strong, and keeps the line of sight clear when the light is dim. In order to achieve the above object, the present invention provides a safety helmet including a cap and a first lens, and an accommodating space is formed in the cap, and a sliding groove is formed in the cap. The first lens is provided with a protruding post. The protrusion is slidably disposed in the sliding slot to be slidable between the first position and the second position, and when the protrusion slides to the first position, the first lens is accommodated in the accommodating space, and when the protruding column is slid Moving to the second position, a portion of the first lens is exposed outside the accommodating space, and the end of the stud extends beyond the accommodating space of the cap. By using the helmet provided by the author, the user can switch the 3 M383315 to use the first lens. The first lens can be pre-installed as a sunglass lens. When the light is strong, the manufacturer can move the convex (four) to The second position is such that the first lens blocks the front of the user's line of sight and provides the use effect of the sunglasses. When the light is dim, the user can slide the stud to the first position, so that the first lens does not cover the user. Sight 'to keep the line of sight clear. [Embodiment] The technical means of the present invention will be described below by way of example only, and the technical scope of the present invention is limited. Referring to Figures 1 and 2, the present invention provides a helmet comprising a cap 10, a first lens 20 and a second lens 3〇. The cap 10 has an accommodating space therein. The cap encloses an opening that communicates with the accommodating space. The cap 10 can be fixed with a buckle n or other fasteners to make the cap available. Wear it on the head and use a buckle to bypass the chin or neck to prevent the cap from falling off the head. A sliding slot 12 is defined in the cap 1 , and an ear portion is defined on each side of the periphery of the cap. The two ears 13 are respectively provided with a joint portion 14 . In other embodiments (not shown) Illustratively, the ends of the two ear portions may be extended and connected to each other to form a full-cover type safety helmet, or the cover may be only semi-spherical to form a half-cover type safety helmet without two ear portions. 'At this time, it is still possible to have a gentleman's part on both sides of the circumference of the cap. The first lens 20 is provided with a protrusion 21, and the protrusion 21 is slidably disposed in the sliding slot 12, so that a portion of the first lens is received in the accommodating space, and the first 4 lens 20 is fixedly mounted thereon. a cap 10, the free end of the stud 21 is exposed from the sliding groove 12 to the surface of the cap 10 and a switching member 22 is mounted on the free end of the stud 21. However, the chute 12 and the stud 21 The number of settings should not be limited to one. It is also possible to open a plurality of chutes in the cap shell, and set a corresponding number of studs on the first lens, and slide the respective studs in each chute, and single or multiple The switching member is coupled to the free end of the stud so that the switching member can move the stud and the first lens to move. In order to further secure the first lens to the cap, the first lens 20 can be pivoted on the two joints n such that the first lens can be pivoted about the line between the two joints. The two sides of the second lens 30 are pivotally disposed on the two joint portions 14, so that the second lens can be rotated about the line between the two joint portions. Referring to FIG. 3, the switching member 22 is slidable by the user to slide the protruding post 21 along the sliding slot 12 to the first position, and the first lens 20 is moved along with the protruding post, so that the first lens is accommodated in the first lens. In the space. Referring to FIG. 4, the switching member 22 can be used by the user to move the slider 21 to slide along the sliding slot 12 to the second position to drive the first lens 20 to move, so that the first lens is partially open. Exposed to the outside of the space. By this means, the assembly can be worn by the user after the assembly is completed, wherein the first lens and the second lens can be made of plastic, acrylic or other light transmissive material to form a light transmissive sheet for use. After being worn, the first lens and the second lens can be viewed forwardly. Meanwhile, the first lens can be configured as a light-shielding lens, a colored lens or a lens that can reflect part of the light, so that the light line M383315 enters the first lens. Only a portion of the light can be transmitted through the first lens, and other light is reflected or absorbed by the first lens to make the first lens have the function of using the lens. When the user wears the creation, depending on the intensity of the surrounding ambient light, the switching member can be moved to block the first lens in front of the user's line of sight, blocking part of the light in the surrounding environment, and avoiding the user being dazzled by excessive light. Even if it is dangerous, the user can also move the switching member to accommodate the first lens in the accommodating space, so as to prevent the light from being blocked by the first lens and being too dark, so that the road ahead cannot be seen clearly. Φ. Referring to FIG. 5, in another embodiment of the present invention, a casing 15 may be fixed to the casing 1 to cover the sliding groove, and a long hole 151 is formed in the casing 15. The hole and the sliding slot are offset from each other without overlapping, and the switching member 22 is slidably disposed on the long hole, so that the switching member can slide along the long hole to drive the protruding post and the first lens to slide along the sliding slot, thereby When it rains, prevent rainwater from directly entering the accommodating space through the chute. In summary, the hard hat provided by this creation contains a first lens that can be used as Sun Lu glasses, and can be switched by the user or not used, providing a convenient way of use. The first lens is normally housed inside the safety cap, which reduces the chance of the first lens being scratched, damaged or contaminated with dust, maintaining the integrity and cleanness of the first lens, and providing good use. In addition, the first lens is mounted on the inner side of the helmet and can be closer to the user's eyes. The lens of the smaller area can completely obstruct the user's line of sight and provide good light shielding. 6 M383315 [Simple description of the diagram] Figure 1 is a perspective view of the creation.
