Abstract
The utility model relates to a sunlight signal mirror, which comprises a reflective mirror and an aiming device. A mirror holder is installed at the back face of the reflective mirror, the mirror holder is a transparent body in the central part, the annular part at the periphery of the mirror holder is a non transparent body, and the thin film type aiming device is arranged between the reflective mirror and the mirror holder and is fixed on the transparent body of the mirror holder. Due to the aiming device that adopts light reflection thin film, the utility model has the advantages of compact structure, thin external shape, light weight, convenient storage and carryover, and simple operation that requires only one hand when used.
Description
The utility model relates to a kind of daylight signalling mirror that utilizes the light reflection to send signal.
Daylight signalling mirror is one of water survival apparatus that is equipped with on the boats and ships, when boats and ships generation casualty, after the person in distress climbs up the life boat raft, utilize daylight signalling mirror with sunlight reflected to searching and rescuing on aircraft or the boats and ships, search and rescue rescue group on aircraft or the boats and ships can see a flash of light on boundless sea bright spot this moment, make the rescue group can determine person in distress's position, implement salvage work.Present employed daylight signalling mirror has light deflector and back sight, be provided with spacing rope between light deflector and the back sight, user's left hand is held light deflector and is placed at the moment, the right hand is held the spacing rope of back sight tensioning and is made back sight perpendicular to the water surface, the user is by the light deflector hole, when the back sight hole is observed object and is is promptly searched and rescued aircraft or boats and ships, rotate light deflector, because light deflector has the mirror hole, when daylight reflexes on the back sight through light deflector, a stain can appear on back sight, continue to adjust light deflector and make stain move to the back sight hole, this moment, the sight line reflected just in time directive object through light deflector, had reached the purpose that sends signal to target.The light deflector of above-mentioned daylight signalling mirror and back sight are captive joint not between being, need two hands to operate simultaneously during use, this to general be not very difficult through the people who uses exercise, and this use is again the big sea of jolting.
The purpose of this utility model is to propose the slim daylight signalling mirror that a kind of light deflector and back sight are fixed together.
The utlity model has light deflector, back sight, for achieving the above object, to take to be provided with microscope base at the back side of light deflector, the central part of microscope base is the transparent body, annulus is an opaque body on every side, and the film-type back sight is arranged between light deflector and the microscope base and is fixed on the transparent body of microscope base.
Above-mentioned film-type back sight central authorities of being made by the regression oriented reflection film have sight hole, are netted around the sight hole.
The loop hole of above-mentioned film-type back sight mesh portion can be any geometric configuration, and the loop hole area is 40%～60% of a netted area.
Above-mentioned microscope base can be split type, and the transparent block of central authorities for being made by transparent engineering plastics is embedded in the ring bodies of being made by opaque engineering plastics.
Above-mentioned microscope base can be an integral type, fixing ring-type coloured film or painted on the surface of the microscope base of being made by transparent engineering plastics.
Fig. 1 is the configuration diagram of the utility model embodiment 1:
Fig. 2 is the configuration diagram of the utility model embodiment 2;
Fig. 3 is a film-type back sight configuration diagram;
Fig. 4 is an optical principle sketch of the present utility model.
Below in conjunction with accompanying drawing and embodiment the utility model is further described.
Embodiment 1 is split type daylight signalling mirror for a kind of microscope base, it has light deflector 1, film-type back sight 2, and the back side of light deflector 1 is provided with microscope base 3, and light deflector can be that metal, glass are aluminized, also can make minute surface by GPPS, aluminizing at its back side forms.The ladder cylindrical transparent block of the middle body 3-1 of microscope base 3 for making with GPPS, annulus 3-2 is for to make with opaque engineering plastics on every side, and transparent block 3-1 is embedded among the annulus 3-2.The film-type back sight is arranged between light deflector and the microscope base, back sight adopts the regression oriented reflection film to make, this kind reflective membrane is a kind of product of the micro glass bead of evenly arranging on the basement membrane that is coated with aluminium or silver, supply is arranged on the market, the regression oriented reflection film has can penetrate light source the characteristic that the next integrated taper light beam of light reflects towards light source direction, film-type back sight 2 central authorities have sight hole 2-1, around the sight hole is netted, the loop hole of mesh portion can be any geometric configuration, as circle, triangle, rhombus, bar shaped etc., the loop hole area is 40%～60% of a netted area, the back sight integral diameter of present embodiment is 18 millimeters, the sight hole diameter is 5.5 millimeters, apart from the sight hole center 3.75 millimeters to locate 18 diameters of rectangular distribution be 1 millimeter loop hole, apart from the sight hole center 5 millimeters to locate 24 diameters of rectangular distribution be 1 millimeter loop hole, apart from the sight hole center 6.25 millimeters to locate 30 diameters of rectangular distribution be 1 millimeter loop hole, the film-type back sight is glued on the transparent block 3-1 of microscope base 3.Be gummed between light deflector and back sight, light deflector and the microscope base, the glue that glues together with back sight must be transparent.
The microscope base 3 of embodiment 2 is an integral type, makes microscope base by GPPS, fixing ring-type coloured film or painted on surface of mirror base to annulus, and other structure is identical with embodiment 1.
Fig. 4 omits the optical principle sketch of refraction factor for the utility model.When light I enters light deflector 1, O reflects at point of incidence, forms reflected light rays I
1, it is back sight 2 that a part of light enters reflective membrane, because reflective membrane regression orienting reflex characteristic, the light that enters reflective membrane reflects to form reflected light rays I
2Be back into exit point O, and reflect once more at the interface, form reflected light rays I at the O point
3, reflected light rays I
3With specular reflection light I
1Be on the same straight line, that enter human eye promptly is reflected light rays I
3, point of incidence O shows as a bright spot on reflective membrane.
Use the utility model--during daylight signalling mirror, only need a hand-held daylight signalling mirror to place at the moment, the sight hole thing that aims at the mark, adjust the angle of daylight signalling mirror, observing by the loop hole of back sight until the user of service has a sparklet on the back sight, continue to adjust daylight signalling mirror, make sparklet move to the sight hole position, at this moment day light reflects just in time directive object through light deflector.
The utility model is owing to adopt light reflecting membrane to make back sight, compact conformation, and slim body, in light weight, be convenient to storage, carry, only need one-handed performance and simple, convenient during use.
