Description

Three times gun sight

Technical field

The utility model is related to rifles to take aim at technical field, and in particular to a kind of three times gun sight.

Background technology

Three times gun sight traditional at present, structure have following deficiency：One, is to meet 3 times of magnifying power, objective focal length It is larger with the matching numerical value of the ratio between eyepiece focal length, therefore light path is longer, so that shank is longer (substantially 110mm).Outside two, object lens Profile, frame effective aperture size are larger, therefore objective lens unit is relatively large in diameter, so that the aobvious heaviness of shank, not readily portable, use； Three, trajectory adjusting parts are mounted on shank, and opposite to protrude, shank volume also can be larger, and product may appear to that comparison is heavy and shadow Ring appearance.

Specific implementation mode

It is new below in conjunction with this practicality to keep the purpose, technical scheme and advantage of the utility model embodiment clearer Attached drawing in type embodiment, the technical scheme in the utility model embodiment is clearly and completely described, it is clear that is retouched The embodiment stated is a part of the embodiment of the utility model, instead of all the embodiments.Based on the reality in the utility model Apply example, the every other embodiment that those of ordinary skill in the art are obtained without making creative work, all Belong to the range of the utility model protection.

As shown in Figure 1, a kind of three times gun sight that the utility model embodiment provides, including shank 9, shank 9 be substantially in Cylinder-like structure, including object lens chamber and eyepiece chamber, are connected between object lens chamber and eyepiece chamber by the smaller unthreaded hole of diameter；Shank 9 Both ends be separately installed with objective lens unit 1 and eyepiece component 8, objective lens unit 1 by object lens inner tube installation in the front end of shank, For eyepiece component 8 by eyepiece inner tube installation in the rear end of shank 9, the focal length of objective lens unit 1 is 23mm~25mm, eyepiece component 8 focal length is 69mm~75mm, and to ensure that visual field is constant, it is three to efficiently control the ratio between objective focal length and eyepiece focal length Under the premise of enlargement ratio, light path is shortened, is made in the eyepiece in 6 length of prism cylinder and the eyepiece component 8 in prism assemblies 11 Tube length degree correspondingly shortens, and finally realizes that shank length (75mm) is more traditional and reduces about 1/3；The object lens of objective lens unit 1 it is effective Aperture is 15mm, keeps object lens outer profile, frame aperture size smaller, and 1 diameter dimension of objective lens unit reduces, and mitigates shank weight.

Shank 9 is inserted with prism cylinder 6 close to the part of objective lens unit 1, and prism cylinder 6 is arranged in the inside of objective lens unit 1, rib Lens barrel 6 is internally provided with prism assemblies 11, in the direction of insertion of prism cylinder 6, the diameter of the diameter of 6 front end of prism cylinder compared with rear end Small, there is spherical structure 4, spherical structure 4 to be contacted with the bottom side mating spherical surfaces of 9 inner wall of shank in the outside of the rear end of prism cylinder 6, ball The top side of shape structure 4 offers sliding slot, the inner wall of shank 9 position corresponding with the radial position of spherical structure along optical path direction Place is equipped with the sliding block 5 for being inserted into the sliding slot, and trajectory tune is equipped at the side wall position corresponding with the front end of prism cylinder 6 of shank 9 Component is saved, trajectory adjusting part is used to adjust the angle of prism cylinder 6, so that the light path of gun sight is adapted with actual trajectory, it should The position of trajectory adjusting part is corresponding with the position of above-mentioned sliding slot, and trajectory adjusting knob 7 is used to adjust the pitching pendulum of prism cylinder 6 It moves and swings.

From the foregoing, it will be observed that object phase light after objective lens unit 1 by being accumulated, that is to say, that light to the front end of prism cylinder 6 When at position, the width of light is less than above-mentioned object lens chamber and the unthreaded hole of eyepiece chamber holder, therefore, the front end of prism cylinder 6 Diameter can also be arranged more much smaller than the rear end of prism cylinder 6；And trajectory adjusting part just can be with the front end phase of prism cylinder 6 Cooperation, since the diameter of the front end of prism cylinder 6 is smaller, so trajectory adjusting knob 7 can be more insinuated into shank 9, makes Its overwhelming majority is embedded into shank 9, to reduce the radial width of gun sight.

In some embodiments, it is cemented doublet and convex lens that objective lens unit 1, which selects cemented doublet, eyepiece component 8, Combination, so as to correct paraxial spherical aberration, correction aberration.

In some embodiments, sliding slot is opened in the top side of spherical structure；Trajectory adjusting part includes trajectory adjusting knob 7 With spring 10, the major part of trajectory adjusting knob 7 is plugged in the top side of shank 9, bottom side and the prism cylinder 6 of trajectory adjusting knob 7 Front end connection, spring 10 compression is arranged between the bottom side inner wall and the front end of prism cylinder 6 of shank 9.Prism cylinder 6 when needed The front end to lower swing when, can be rotated down trajectory adjusting knob 7, push the front end of prism cylinder 6；When needed When the front end of prism cylinder 6 is swung up, the trajectory adjusting knob 7 can be rotated up, is acted on by the elastic force of spring 10 And the front end of prism cylinder 6 is made to be swung up；When prism cylinder 6 swings when needed, trajectory adjusting knob 7 can be adjusted On lateral adjustments part, so that the front end of prism cylinder 6 is swung.

In some embodiments, the rear end of prism cylinder 6 is equipped with bulb pressure ring 2, and bulb pressure ring 2 passes through caging bolt 3 and mirror The inner wall of body 9 connects, specifically, caging bolt 3 is mounted on the side wall of shank 9, caging bolt 3 penetrates into bulb pressure ring 2； And bulb pressure ring 2 is contacted with spherical structure 4, for preventing prism cylinder 6 from deviating from from the shank.When installing prism cylinder 6, The caging bolt 3 is rotated outward first, prism cylinder 6 is enable to be inserted into object lens chamber by the front end of shank 9, when prism cylinder 6 After being inserted into shank 9, the caging bolt 3 is rotated inward, bulb pressure ring 2 is made to be stuck in the outside of spherical structure 4, to prevent prism cylinder 6 skid off shank 9.

The three times gun sight of the present embodiment, it is long overweight to solve traditional three times gun sight shank, ensures its optical property Constant, visual field is constant, fast, easily converts.

Finally it should be noted that：Above example is only to illustrate the technical solution of the utility model, rather than its limitations； Although the utility model is described in detail with reference to the foregoing embodiments, it will be understood by those of ordinary skill in the art that： It still can be with technical scheme described in the above embodiments is modified, or is carried out to which part technical characteristic etc. With replacement；And these modifications or replacements, various embodiments of the utility model technology that it does not separate the essence of the corresponding technical solution The spirit and scope of scheme.
