Description

Fast ajustable sighting lens

The present invention relates to a kind of calibration marker that in being suitable for the gun sight that uses with the configuration of shooting type weapon, is provided with the aiming of raising weapon and the fast ajustable sighting lens of fire accuracy, belong to a kind of observation aiming optical instrument.

For shooting class weapon, the configuration gun sight can significantly improve pointing velocity, precision and shooting average, and ajustable sighting lens, it is the basic link that hit rate is guaranteed that aiming point is overlapped with point of impact.Existing gun sight, usually constitute by lens barrel, optical aiming system and calibrating installation, when using with weapon configuration if not by the Other Instruments assisted calibration, need relative position through trial fire, observation aiming point and point of impact, estimate then and adjust direction and adjustment amount, adjust ajustable sighting lens by calibrating installation.Said process often needs to repeat repeatedly, spends many times just can finish.In actual use, the existence of the problems referred to above not only brings inconvenience to the user, and has influenced the good serviceability of gun sight.

In the patent No. is 4403421 United States Patent (USP), disclose a kind of deviation mirror two ends in gun sight and set up two graticles separately, promptly on the imaging surface of deviation mirror front end, set up the riflescope of an auxiliary graticle, assist location by this graticle, get final product ajustable sighting lens through once firing for adjustment, solved above-mentioned asking a question, yet, this patent is only at resembling the adjustment gun sight, and it is comparatively complicated to exist structure, use easy inadequately problem, the mode that auxiliary graticle is set is also more single, so its practicality is relatively poor, so far not yet by practical application.

The objective of the invention is to avoid the weak point of above-mentioned existence and a kind of fast ajustable sighting lens that is provided with calibration marker is provided, it can not only finish the calibration tasks of gun sight quickly and easily, and structure is very simple and reliable.

Purpose of the present invention is realized by following scheme: have lens barrel 1, the lens barrel Inner Front End is equipped with object lens 3, the rear end is an eyepiece 7, in lens barrel, also be equipped with relay lens 5 and graticle 6, constitute optical aiming system, and disposing calibrating installation 2, its difference is to be provided with a calibration marker 4 on the target imaging surface of gun sight optical aiming system.

Press such scheme, for graticle guiding mechanism gun sight, calibration marker is that imaging is on the target imaging surface; Object guiding mechanism gun sight, the calibration marker imaging is on the target imaging surface that is adjusted between optical element and the target.

According to such scheme, main feature of the present invention is to be provided with a calibration marker on the target imaging surface of gun sight, the influence that the relative position of this calibration marker and target is not adjusted by calibrating installation, be usually located on the optical axis of gun sight and relative static with the dispose weapon that uses, this just provides a relative static reference point with target for aiming trial fire, datum mark as calibration, during use, earlier calibration marker 4 is aimed at certain some trial fire on the target, will calibration marker after the trial fire aim at this point on the target, thereafter by calibrating installation the actual point of impact center 23 that moves to is adjusted at the sighting mark center 24 of gun sight, sighting mark center and center of impact are coincided, promptly finish the calibration of gun sight, as Fig. 6,7, shown in 8.The present invention has just set up a calibration marker in former gun sight, thereby structure is very simple and reliable, use also very easy, at short notice, only use takes several bullets, just can be fast and finish the calibration tasks of gun sight effectively, to compare with existing traditional calibration steps, the efficient of its calibration and precision can be significantly improved.The present invention is practical, is easy to extensive use.
