Description
Technical field
The utility model relates to the collapsible adjustable focus stereoscope that is used to watch stereoscopic photograph.
Background technology
General stereoscopic photograph must just can be seen three-dimensional effect by stereoscope.Common stereoscope has a camera bellows formula stationary housing, the front end of housing be transparence in order to advance light, its near-end is established binocular, lantern slide (reversal film) must be loaded on the sheet folder, and the sheet folder is inserted in the visor front end, can be seen the stereoeffect of scenery by eyepiece.There is following shortcoming in existing stereoscope: (1) housing is not collapsible, and volume is bigger, and inconvenience is deposited and carried.(2) stationary housing Nonadjustable focusing can not adapt to the people of different eyesights.Adjustable focus person is also arranged, complex structure, cost is higher.(3) adopt 135 reversal films must add the sheet folder as picture, the cost height, and the visual field is less.(4) housing adopts cast molding, complex process, cost height.
Summary of the invention
The purpose of this utility model is to provide a kind of collapsible adjustable focus stereoscope, and this stereoscope can be folded into tabular in time spent not, and volume is urinated in depositing, carrying; Adjustable focal length is to adapt to the people of different eyesights; As picture, cost is low and the visual field is big with photo of enlargement of color photo; Simple with shear forming technology, with low cost.
The collapsible adjustable focus stereoscope of the utility model is achieved in that rectangle eyepiece plate and picture liner plate on the other side is set, the long limit of eyepiece plate is connected with main connecting plate with the long limit of picture liner plate, establish fold line in the joint, the minor face of eyepiece plate and liner plate connects with side plate, establish fold line in the joint, be provided with the fold line parallel with the eyepiece plate at the middle part of main connecting plate, broken line is established at middle part at side plate, offer the picture socket at picture liner plate and a main connecting plate intersection, main connecting plate and side plate are made with the translucent plastic sheet material.
The collapsible adjustable focus stereoscope of the utility model, its main connecting plate and side plate adopt the translucent plastic sheet material to make, and this material has certain rigidity and flexible, can fold, and has light transmission again.Main connecting plate and side plate adopt folding mode to connect eyepiece plate and picture liner plate, when pushing eyepiece plate and picture liner plate simultaneously, biside plate is inwardly folding along broken line, main connecting plate is folded-out, whole visor will become tabular, and in the paper bag of the envelope-sized of can packing into, volume ratio housing shape user mode greatly reduces, tens pairs and even tens secondary visors can be loaded in the little box body, be brought great convenience to packing, transport, carrying all.The utility model housing parts is sheared with plastic sheet entirely and is made, and only eyepiece adopts cast molding, and not only material price is cheap, and manufacturing process is simple, and cost is very low.Add that picture adopts photo of enlargement of color photo to print off, need not add the sheet folder, lower than lantern slide cost, because of this stereoscope more much lower than the cost of common stereoscope; The housing of this stereoscope has better light transmission, directly uses photo of enlargement of color photo as picture (stereoscopic photograph of special production), and the area of image is big, and the visual field is also big, seems more comfortable; This visor pushes two main connecting plate fold line positions with finger in use, and main connecting plate and side plate are upheld simultaneously, constitutes the deltiod housing, is watched attentively the picture on opposite at this moment by eyepiece, can see having relief scenery.Because main connecting plate has certain flexible, when the extruding main connecting plate, main connecting plate still has outside tension force, with the degree that the hand control main connecting plate is upheld, can adjust distance between eyepiece and picture, reaches the purpose of adjusting focal length, uses with the people who adapts to different eyesights.
Description of drawings
Fig. 1 is the utility model structural representation
Fig. 2 is embodiment of the present utility model and user mode.
EmbodimentAs shown in Figure 1, the collapsible adjustable focus stereoscope of the utility model is provided with rectangle eyepiece plate 1 and picture liner plate 3 on the other side, the long limit of eyepiece plate is connected with main connecting plate 5 with the long limit of picture liner plate, establish fold line in the joint, the minor face of eyepiece plate and liner plate connects with side plate 2, establish fold line in the joint, be provided with the fold line parallel 51 with the eyepiece plate at the middle part of main connecting plate, establish broken line 21 at the middle part of side plate, offer photo socket A at picture liner plate and a main connecting plate intersection, main connecting plate and side plate are made with the translucent plastic sheet material.The eyepiece plate of this stereoscope, main connecting plate, picture liner plate can be sheared with a sheet material and be shaped, and extrude fold line between each plate, bonding its end of butt joint, folding back.Side plate can cut out separately, establishes narrow contact pin at two ends, and contact pin and side sheet room are made fold line, adheres to eyepiece plate and liner plate edge with contact pin.Adhere to eyepiece 11 in the eyepiece hole of eyepiece plate, for the facility on making, two attached plates of eyepiece of connection are set, eyepiece and attached plate thereof are become one by the transparent plastic casting, and attached plate of eyepiece and eyepiece plate are pasted together.Because this stereoscope is after folding, built-in side plate and eyepiece have certain thickness, thereby can two parallel fold lines 511,512 be set at the main connecting plate middle part, as shown in Figure 2, can guarantee visor smooth after folding like this.Picture 6 inserts the visor housing by picture socket 4, views and admires for the user.
