But existing binocular ophthalmoscope display, compact more in order to make product structure, volume is littler, adopt a lens structure, quite high to the optical device requirement, for example: the optical prism structure that adopts three free form surfaces, miniscope, optical device and eyes are not on the optical axis of straight line, adopt the optical prism of three free form surfaces, complex structure, difficulty of processing is big, the manufacturing cost height, workman's assembling is difficulty comparatively, and product quality be cannot say for sure to be unfavorable for large-scale production by card.
(3) utility model content:
In order to overcome the deficiencies in the prior art, the utility model provides a kind of simple in structure, handling ease, low cost of manufacture, binocular display light nuclear core pleasant, easy to adjust.
The utility model is to realize by following technical scheme:
A kind of binocular display light nuclear core, comprise picture frame, miniscope and optical mirror slip group, miniscope is installed in the front of picture frame, picture frame has two lens barrel cavitys, the optical mirror slip group is installed on the picture frame, utilize the optical mirror slip group to amplify the picture of the broadcast of miniscope, it is characterized in that: the optical mirror slip group is made up of two spherical lenses, is respectively concavees lens and convex lens.
Above-mentioned described concavees lens and convex lens adopt the mode of spacer ring location.
Above-mentioned described concavees lens and convex lens are set in spacer ring the inside, are nested into the lens barrel cavity then, and the convex lens that will protrude the lens barrel cavity with trim ring on the picture frame back install and fix.
The distance of exit pupil scope of above-mentioned described convex lens is: 13mm to 18mm, exit pupil diameter scope: 7mm to 10mm.
The horizontal width scope of the convex lens of above-mentioned described close eyes: 15mm to 20mm.
Above-mentioned described miniscope is a LCD display.
Between above-mentioned described picture frame and the miniscope optical axis governor motion is set, this optical axis governor motion comprises cylinder and the miniscope upper groove composition that protrudes previously from picture frame, and cylinder embeds the groove the inside.
The focal power of above-mentioned described convex lens is between 0.03 to 0.45, and the focal power of concavees lens is between-0.03 to-0.35.
The utility model compared with prior art has following advantage: 1) optical mirror slip group of the present utility model is made up of two spherical lenses, is respectively concavees lens and convex lens, and is simple in structure, handling ease, low cost of manufacture; 2) people's eyeball, miniscope and optical mirror slip group are in same straight line optical axis, and assembling is simple, and the miniscope position is regulated easily; 3) the distance of exit pupil scope of convex lens is: 13mm to 18mm, and exit pupil diameter scope: 7mm to 10mm, horizontal width scope: 15mm to 20mm effectively increases the comfort level that the human eye watches image; 4) concavees lens and convex lens adopt the mode of spacer ring location, improve installation accuracy and properties of product; 5) the optical axis governor motion is set between picture frame and the miniscope, can is having extreme position to realize arbitrarily angled adjustment.
(4) description of drawings:
Below in conjunction with accompanying drawing the utility model is done detailed explanation:
Fig. 1 is an exploded view of the present utility model;
Fig. 2 is the A-A partial enlarged drawing of Fig. 1;
Fig. 3 is a front elevation of the present utility model;
Fig. 4 is a rear view of the present utility model;
Fig. 5 is a structure cut-open view of the present utility model;
Fig. 6 is the B-B enlarged drawing of Fig. 5.
(5) embodiment:
As Fig. 1, Fig. 2, Fig. 3, Fig. 4, Fig. 5, shown in Figure 6, the utility model comprises picture frame 1, miniscope 2 and optical mirror slip group, miniscope 2 is installed in the front of picture frame 1 by screw 7, picture frame 1 has two lens barrel cavitys 10, the optical mirror slip group is installed on the picture frame 1, utilize the optical mirror slip group to amplify the picture of the broadcast of miniscope, the optical mirror slip group is made up of two spherical lenses, is respectively concavees lens 3 and convex lens 4.Concavees lens 3 and convex lens 4 adopt the mode of spacer ring 5 location.Concavees lens 3 and convex lens 4 are set in spacer ring 5 the insides, are nested into lens barrel cavity 10 then, and the convex lens 4 that will protrude lens barrel cavity 10 with trim ring 6 on picture frame 1 back install and fix, and trim ring 6 is to be installed on the picture frame 1 by screw 11.The distance of exit pupil scope of convex lens 4 is L2:13mm to 18mm, exit pupil diameter D scope: 7mm to 10mm.The horizontal width L1 scope of convex lens 4: 15mm to 20mm.Miniscope 2 is LCD display.Between picture frame 1 and the miniscope 2 the optical axis governor motion is set, this optical axis governor motion comprises cylinder 8 and miniscope 2 upper grooves 9 compositions that protrude previously from picture frame 1, and cylinder 8 embeds grooves 9 the insides.The focal power of convex lens 4 is between 0.03 to 0.45, and the focal power of concavees lens 3 is between-0.03 to-0.35.
Because when miniscope 2 and optical mirror slip group optical axis are inconsistent, need to adjust the position of two miniscopes 2, this just needs the optical axis governor motion, this optical axis governor motion comprises cylinder 8 and miniscope 2 upper grooves 9 compositions that protrude previously from picture frame 1, cylinder 8 embeds groove 9 the insides, and groove 9 is much larger than cylinder 8, and miniscope 2 can move up and down so, when miniscope 2 is consistent with optical mirror slip group optical axis by the time, tighten just passable again with screw 7.
