Description

Internal red-point aiming structure

Technical field

The invention provides a kind of internal red-point aiming structure, especially refer to utilize virtual pointolite to be projected to parallel again ejaculation behind the object lens, penetrate so that the simulated point light source is parallel from afar, make and take aim at the effect that tool reaches interior red some demarcation, and be aided with the percentage that coating technique is controlled the ruddiness of reflection spot light source in eyepiece and objective lens surface, with reach shorten take aim at tool length, object lens strengthen and the accurate effect of projection of light source.

Background technology

General gun is used take aim at fast tool be divided into usually in two kinds of red point and outer red points, as the term suggests it be exactly in close encounters war, the user can be broken through with the critical position that the very short time is aimed at the enemy fast and accurately, it is directly to be penetrated on one's body the enemy by the ruddiness that the laser pointer device is sent that common outer red point is taken aim at tool, to make things convenient for the user to know that immediately whether muzzle is to aim at enemy's key, though this kind mode can reach the effect that slewing is hit, but its shortcoming is very easy position of exposing oneself to the open air, whereabouts, and when around when too bright, its outer red point is taken aim at the ruddiness that tool sends and can not seen Chu easily, and the position that causes the user can't identification ruddiness to be shone, so red point was taken aim at tool in research and development were designed, benefit need not be afraid of too bright exactly all around or be seen ruddiness by the enemy, see also Fig. 4, shown in Figure 5, be use synoptic diagram () commonly used and use synoptic diagram (two), the principle that red point is taken aim at tool in general is that parallel the penetrating of red point seen in emulation from far place, find out by knowing among the figure, should in red point take aim at tool and utilize a concave mirror A with circular arc R angle, the center of circle C of its concave mirror A is for being positioned on the main axis, focal point F then is positioned at the place apart from half of center of circle C and concave mirror A, hot when penetrating toward concave mirror A by focal point F, its light can be via concave mirror A reflection back by parallel ejaculation on the main shaft, promptly satisfy incident angle=reflection angle, so user's eyes just can receive the similar red point of being demarcated by a distant place of emulation, when the visual concave mirror A of user, can see the corresponding red point of emulation according to the position of own eyes, with this form have in red point take aim at tool B, and then allow the user can slewing enemy's key, also needn't worrying can do by myself exposes whereabouts to the open air, yet this kind structural design still has following disappearance when using:

After red point is taken aim at tool B in gun is loaded onto, the user must be with eyes near concave mirror A, look for the red point of the emulation of being reflected on the concave mirror A, but the light that general concave mirror A is reflected, be will very just can be by parallel ejaculation near the light of main shaft, the effect that just can have the red point of emulation, when if the user sees the edge of concave mirror A, its concave mirror A edge can be by parallel ejaculation, and can cause the imaging of the red point of emulation to distort, because the diameter of concave mirror A is more little, the scope of the parallel ejaculation of its light can be littler, and then make the scope in the whole visual field can be limited in very narrow region, so certainly will will strengthen the diameter of concave mirror A, just can make the whole visual field broader, but after strengthening the diameter of concave mirror A, can make also relative the zooming out of focal point F of concave mirror A, and cause distance elongated (as shown in Figure 5) between light source and the concave mirror A, so, the whole mechanism volume that makes interior red point take aim at tool B can extend, and then the overall weight of increase gun, still have improvable space to exist and highlighted its concave mirror structure.

Also there is the mode of utilizing another kind of laser projection to reach the purpose that interior red point is taken aim at tool, this kind common structure is the light that utilizes laser diode to send, reach the purpose that is crossed as picture via repeatedly reflecting, this kind mode needs very accurate adjustment to proofread and correct, could form and be crossed as picture, employed amount of glass is also quite a lot of, make whole cost quite expensive, if red point is taken aim at the words that tool clashes into accidentally or drops in this kind, make the reflection angle skew of laser ruddiness easily, be crossed as picture and can't form, and this kind laser injures the eyes of human body easily, still remain to be improved so plant common structure.

Therefore, how to solve above-mentioned problem commonly used and disappearance, the direction place of improving for institute of the relevant manufacturer desire research of being engaged in the industry.
