Stabilization and safety glasses structure that prevents fogging, water accumulation and water ingress. [Prior Art] In general construction, workers often wear safety glasses to protect the eyes from foreign objects, such as dust, small gravel, and water splashes during construction. The traditional safety glasses are formed by the frame and the lens being engaged with each other. However, the conventionally designed snap-fit structure is extremely simple, and it is easy to make the frame and the lens fall off when the safety glasses are removed or the buckle is removed. In addition, the traditional safety glasses are easy to fog when the temperature changes, or under the influence of the workers' suffocation and body temperature, which causes the construction workers to have poor visibility and relatively increase the danger during construction. In order to solve the fogging problem of the aforementioned lenses, the safety glasses have the so-called air hole design, but the conventional air holes will form a hole in the safety glasses, and the foreign objects such as ash, small gravel and water flowers still have the opportunity to enter the safety glasses, and Causes the eyes of the person to be injured. In view of the above problems, as shown in the fourth figure of the US Patent No. 2004/0117898, it is designed to improve the design of the fogging problem and the safety of the eye parts, however, when splashing water (such as rain) is safely splashed. In the case of glasses, the water will cause water accumulation in the pores, which will cause the pores to lose their effect, and after the water is accumulated, the overflow problem will occur and M349498 will be produced. The water inflow phenomenon is not ideal. Therefore, how to create a safety glasses structure, so that the safety glasses structure can improve the joint stability and prevent fogging, water accumulation and water inflow, will be actively exposed by the creative office. [New content] In view of the shortcomings of the above-mentioned conventional safety glasses structure, the creator feels that he has not perfected it, exhausted his mind to study and overcome it, and developed a kind of experience based on his accumulated experience in the product industry for many years. Safety glasses structure, in order to achieve the purpose of improving joint stability and preventing fogging, water accumulation and water ingress. The main purpose of this creation is to provide a safety eyeglass structure that is designed to improve joint stability and prevent fogging, water accumulation and water ingress. In order to achieve the above object, the safety eyeglass structure of the present invention comprises: a frame, which is annular and surrounds an opening, the frame has a frame fastening portion, a Φ frame engagement portion, a second frame fastening portion, and at least one The upper guide groove, the at least one J guide groove and the upper groove are disposed on the frame, the mirror frame engaging portion is disposed under the frame, and the two frame fastening portions are respectively disposed on the frame On the two sides of the frame, the upper guide groove is obliquely recessed on the front side of the frame and communicates with the 'opening hole and the outside of the frame. The lower guiding groove is recessed up and down under the front side of the frame and communicates with the opening. Outside the frame, the upper groove is recessed on the upper side of the frame, the two frame fastening portions respectively have a stopping portion; a lens covering the opening and the lens periphery covering the upper guiding groove and the lower guiding a lens groove having a lens engaging portion, a lens engaging portion and a second lens fastening portion, 7 M349498, the lens fastening portion is disposed above the lens and fastened to the frame fastening portion, and the lens is engaged The portion is disposed under the lens and is engaged with the frame engaging portion, The two lens fastening portions are respectively disposed on the two sides of the lens and are respectively fastened to the two frame fastening portions. The two lens fastening portions respectively have a fastening hole; and two elastic buckles respectively have a top flange The two elastic buckles are respectively inserted into and fastened to the two fastening holes, and the two top flanges respectively abut against the two stoppers. Therefore, by designing the above various fastening structures, the frame and the lens can be firmly joined to each other when worn, and the bonding stability can be improved. In addition, by lowering the upper side of the front side of the frame from the bottom to the upper side, the upper guide groove and the lower side of the front side of the frame are downwardly and downwardly recessed, and when the safety eyeglass structure of the present invention is worn, The air will be discharged from the bottom to the top: to achieve the purpose of gas circulation, the mirror will be fogged and designed in the direction of the oblique direction. Dust, small gravel, and protection: The safety glasses jeopardize the design of the construction personnel's eyes. The lower diversion channel of the L-Down is known from the bottom to the constant law of the mass, when the same air is inside the large lens; It will become larger, and the defogging efficiency of the air entering the outer mirror village is a jet airflow, which can improve the heat removal efficiency in the lens in addition to the mirror. Design, the design of the water flow trough is tapered from the bottom to the top and the upper groove is the outlet. When the female full glasses, the upper diversion trough is tapered from bottom to top: the water is out, so the water flower is not easy to enter the safety glasses, the two sides of the groove Under the flow of 'not easy to accumulate water, the M349498 on the "slot overflow safety eye, it will also follow the oblique concave = upper guide trough and the inner surface of the lens flow, then smoothly under the downward direction of the concave The outflow of the trough can effectively prevent the water from coming into contact with the eyes.

The frame 2 can have an annular flexible edge 2, and the ring is disposed on the rear side of the frame 2, and the two elastic buckles 4 can respectively have two sockets 4 2, which can be respectively sleeved 5 bis collar end. Therefore, when used, the sleeve 5 can be worn on the head of the constructor (not shown), and the annular flexible edge 2 7 can maintain the adhesion between the frame 2 and the head of the constructor. Comfort. In addition, the two elastic buckles 4 can have at least one wedge-shaped protrusions 4 4 to slide the retaining ring sleeves 5 . The wedge-shaped bumps 4 4 are disposed outside the elastic buckle 4 , and can also be disposed on the inner side. Therefore, in combination with the above, the frame 2 and the lens 3 can be joined to each other when the safety eyeglass structure 1 of the present invention is worn or removed, or when the elastic buckle 4 is removed for cleaning or maintenance. They do not fall off each other, causing the frame 2 or the lens 3 to fall to the ground and be damaged. In addition, the lower guide groove 2 5 1 is recessed from the lower side to the upper side of the front side of the frame 2, and the lower guide groove 2 5 2 is lowered from the lower side to the lower side of the front side of the frame 2, and the wearer is worn. When the safety glasses structure 1 is created, the air will be discharged from the bottom to the top, and the gas circulation can be achieved, so that the lens 3 can be prevented from fogging, and the oblique direction is designed in the direction of the dust, small stones. Foreign objects such as gravel and water flowers will not cause problems in entering the safety glasses and endangering the eyes of the construction personnel. In addition, the upper guide groove 2 5 1 and the lower guide groove 2 5 2 are respectively designed to be tapered from bottom to top, and it is known from the law of mass observance that when the same air flows from a large cross-sectional area to a small cross-sectional area 13 M349498 At this time, the flow rate becomes large, which allows the air to enter the lens 3 and exit the lens 3 to be an jet stream. In addition to improving the defogging efficiency in the lens 3, the heat removal efficiency in the lens 3 can also be improved. Furthermore, by the design of the upper guide groove 2 5 1 from the bottom to the top and the design of the upper groove 26, when the splash is splashed on the safety glasses, the upper guide groove 2 5 1 is tapered from the bottom to the top to cause the exit to be small. And the airflow is sprayed out, so the water flower is not easy to enter the safety glasses, and the water spray can flow down the two sides of the upper groove 26, which is less prone to water accumulation. If water overflows from the upper guide groove 2 5 1 into the safety glasses 1 It will also flow down the concave guide groove 2 5 1 and the inner surface of the lens 3, and then smoothly flow out below and below the concave guide groove 2 5 2, which can effectively prevent water from being touched. eye. As mentioned above, this creation is fully in line with the three requirements of the patent: novelty, advancement and industrial availability. In terms of novelty and advancement, the structural improvement can be used to improve the joint stability and prevent fogging, water accumulation and water inflow; in terms of industrial availability, the use of this creation The products can fully meet the needs of the current market.
