Description
Technical field
The utility model belongs to miniscope technical field, especially relates to a kind of adjustable focus eyepiece for miniscope.
Background technology
Miniscope is the hot product showing field in recent years, for virtual reality, is usually used in spectacle, head-mounted display apparatus.Because the eye eyesight of people is different, need again the image of human eye direct viewing miniscope, thus be not suitable for myopia, crowd that long sight is serious uses.Although part has possessed focusing function in the eyepiece that present telescope, microscope are supporting, the crowd that can adapt to different eyesight has used, its complex structure, complex manufacturing, cost is high, is not suitable for supporting the use with miniscope, and weight is large, is not suitable for head-mount and uses.The focal length setting mechanism of such as traditional telescope ocular is by eyepiece stalk, eyepiece mount, focusing mount and guide pin composition, guide pin is connected on eyepiece stalk, and focusing mount curved surface mills out the skewed slot coordinated with guide pin together, when focusing mount rotates, skewed slot drives guide pin to do tandem motion, thus make the elastic focusing of eyepiece, due to guide pin, focusing mount processes by metalwork, and both do accurate transmission cooperation, therefore higher to the requirement on machining accuracy of guide pin and focusing mount, its requirement on machining accuracy is high, production cost is high, complex process, production efficiency is low, improve in product at it, eyepiece mount is fixed on telescope body, bottom and the eyepiece mount of eyepiece stalk form screw-driven and coordinate, the top of eyepiece stalk coordinates with the transmission of focusing mount formative gear, pin coordinates with the arc guide barrel on focusing mount, and with so reducing production difficulty and cost after improvement, but it still utilizes closely cooperating between gear, screw thread, still higher to the requirement of machining precision, manufacturability is still complicated.
Summary of the invention
The purpose of this utility model be improve prior art deficiency and provide a kind of utilize the stroke post on eyepiece holder and the screw-internal thread fit in focusing handwheel to carry out eyepiece focusing, structure is simple, easy to operate, cost is low, be adapted at miniscope using, adapting to the adjustable focus eyepiece for miniscope of different crowd.
The purpose of this utility model realizes like this, a kind of adjustable focus eyepiece for miniscope, by being arranged on eyepiece upper casing, eyepiece stalk in eyepiece lower casing, miniscope, convex lens holder, convex lens and handwheel composition, be characterized in being provided with column in eyepiece stalk, on column, cover has spring, eyepiece barrel has stroke groove, convex lens holder is provided with the pilot hole matched with the column of eyepiece stalk, convex lens holder surface is provided with the stroke post matched with the stroke groove on eyepiece stalk, handwheel inside surface is provided with internal thread, stroke post on convex lens holder stretches in internal thread.
In order to realize the purpose of this utility model further, it can be the spacing catch of the shift length be provided with on convex lens holder for limiting convex lens.
The utility model has following distinguishing feature and good effect with existing compared with technology: this is provided with column in eyepiece stalk, on column, cover has spring, eyepiece barrel has stroke groove, convex lens holder is provided with the pilot hole matched with the column of eyepiece stalk, convex lens holder surface is provided with the stroke post matched with the stroke groove on eyepiece stalk, handwheel inside surface is provided with internal thread, stroke post stretches in internal thread, pressure is applied to convex lens holder by rotating handwheel internal thread, stroke post on convex lens holder mates with the stroke groove on eyepiece stalk, pilot hole on convex lens holder mates with the column on eyepiece stalk, jointly limit the moving direction of convex lens holder, thus realize the object of focusing, the moving direction of convex lens holder is different according to handwheel sense of rotation, change prior art to utilize and coordinate the focusing carrying out eyepiece between screw thread with screw thread, because its component structural is complicated, complex manufacturing, high in cost of production problem, the utility model directly utilizes the stroke post on eyepiece holder and the screw-internal thread fit in focusing handwheel to carry out the focusing of eyepiece, its structure is simple, easy to operate, production technology simplifies, cost is low, be adapted at miniscope uses, adapt to different crowd use, spacing catch, for limiting the shift length of convex lens, ensure that safety.

Embodiment
Embodiment 1, a kind of adjustable focus eyepiece for miniscope, with reference to Fig. 1, Fig. 2, Fig. 3, Fig. 4, it is eyepiece stalk 1, miniscope 2, convex lens holder 4, convex lens 5, eyepiece upper casing 14 is arranged on handwheel 7, in eyepiece lower casing 13, column 8 is provided with in eyepiece stalk 1, on column 8, cover has spring 3, eyepiece stalk 1 wall has stroke groove 9, convex lens holder 4 is provided with the pilot hole 10 matched with the column 8 of eyepiece stalk 1, convex lens holder 4 surface is provided with the stroke post 11 matched with the stroke groove 9 on eyepiece stalk 1, handwheel 7 inside surface is provided with internal thread 12, stroke post 11 stretches in internal thread 12, this forms a kind of structure of the utility model type.
Embodiment 2, for an adjustable focus eyepiece for miniscope, with reference to Fig. 2, Fig. 3, Fig. 4, Fig. 5, be on the basis of embodiment 1, be the spacing catch 6 of the shift length be provided with on convex lens holder 4 for limiting convex lens 5, other are identical with embodiment 1.
Installation of the present utility model is first coordinated from bottom to top by eyepiece stalk 1 to be installed in eyepiece lower casing 13, respectively miniscope 2 is installed on the bottom of eyepiece stalk 1 again, spring 3 is placed on the column 8 that eyepiece stalk 1 is provided with, then being coordinated by convex lens holder 4 is loaded in eyepiece stalk 1, and spacing catch 6 is coordinated the top being loaded on eyepiece stalk 1, again handwheel 7 is threaded onto the outside that appropriate location is placed on eyepiece stalk 1, handwheel 7 internal thread 12 is coordinated with the stroke post 11 on convex lens holder 4, finally eyepiece upper casing 14 is coordinated installation with eyepiece lower casing 13.
When using the utility model, during adjustment handwheel 7, handwheel internal thread 12 applies pressure to convex lens holder 4, stroke post 11 on convex lens holder 4 mates with the stroke groove 9 on eyepiece stalk 1, pilot hole 10 on convex lens holder 4 mates with the column 8 on eyepiece stalk 1, jointly limits the moving direction of convex lens holder 4, when handwheel 7 rotates, internal thread 12 drives convex lens holder 4 to move, thus realizes focusing.The moving direction of convex lens holder 4 is different according to the direction of internal thread; In the above-described embodiments, when handwheel 7 turns clockwise, convex lens 5 move to miniscope 2 direction, and Compress Spring 3, when being rotated counterclockwise convex lens 5 under the effect of spring 3 elastic force away from miniscope 2.
