Technical field
The invention belongs to miniscope technical field, especially relate to a kind of adjustable focus mesh for miniscope
Mirror.
Background technology
Miniscope is the hot product of display field in recent years, for virtual reality, is usually used in spectacle, wear-type
In display device.Because the eye eyesight of people is different, need the image of human eye direct viewing miniscope, so being not suitable for again
Myopia, hypermetropia serious crowd use.Although partly having been provided with the supporting eyepiece of present telescope, microscope focusing
Function, can adapt to different visions crowd use, but its complex structure, complex manufacturing, high cost, be not suitable for micro-
Escope supports the use, and weight is big, is not suitable for head-mount and uses.The focus adjustment machine of for example traditional telescope ocular
Structure is made up of eyepiece stalk, eyepiece mount, focusing mount and guide pin, and guide pin is connected on eyepiece stalk, and mills out on focusing mount curved surface together
With the skewed slot of guide pin cooperation, when focusing mount rotates, skewed slot drives guide pin to do tandem motion, so that eyepiece is elastic
Focusing, because guide pin, focusing mount are processed by metalwork, and both do the transmission cooperation of precision, therefore to guide pin and
The requirement on machining accuracy of focusing mount is higher, and its requirement on machining accuracy is high, and production cost is high, complex process, low production efficiency；At it
Improve in product, eyepiece mount is fixed on telescope body, the bottom of eyepiece stalk and eyepiece mount form screw-driven cooperation, eyepiece
The top of cylinder and focusing mount form gear drive cooperation, the arc guide barrel cooperation on pin and focusing mount, although permissible after improvement
Reduce production difficulty and cost, but it still utilizes the tight fit between gear, screw thread, the requirement to machining accuracy is still relatively
Height, manufacturability is still complicated.
Content of the invention
It is an object of the invention to improving the deficiency of prior art and providing the stroke post in a kind of utilization eyepiece fixed seat
With the screw-internal thread fit in focusing handwheel carry out the focusing of eyepiece, structure is simple and convenient to operate, low cost, be suitable for miniature aobvious
Show on device using, adapt to different crowd the adjustable focus eyepiece for miniscope.
The object of the present invention is achieved like this, a kind of adjustable focus eyepiece for miniscope, is by being arranged on mesh
Eyepiece stalk in mirror upper casing, eyepiece lower casing, miniscope, convex lenss fixed seat, convex lenss and handwheel composition, are characterized in mesh
It is provided with column in lens barrel, column is cased with spring, eyepiece barrel has stroke groove, convex lenss fixed seat is provided with and eyepiece stalk
The location hole that column matches, the fixing seating face of convex lenss is provided with the stroke post matching with the stroke groove on eyepiece stalk, handwheel
Inner surface is provided with female thread, and the stroke post in convex lenss fixed seat stretches in female thread.
In order to realize the purpose of the present invention further, can be to be provided with for limiting convex lenss in convex lenss fixed seat
The spacing catch of shift length.
The present invention has following distinguishing feature and good effect with existing compared with technology：This is to be provided with eyepiece stalk
Column, column is cased with spring, and eyepiece barrel has stroke groove, and convex lenss fixed seat is provided with and is matched with the column of eyepiece stalk
Location hole, the fixing seating face of convex lenss is provided with the stroke post matching with the stroke groove on eyepiece stalk, and handwheel inner surface is provided with
Female thread, stroke post stretches in female thread, applies pressure by rotating handwheel female thread to convex lenss fixed seat, convex lenss are fixed
Stroke post on seat is mated with the stroke groove on eyepiece stalk, the column on the location hole in convex lenss fixed seat and eyepiece stalk
Join, jointly limit the moving direction of convex lenss fixed seat, thus realizing the purpose focused, the moving direction of convex lenss fixed seat
Different according to handwheel direction of rotation, change prior art using the cooperation between screw thread and screw thread carry out eyepiece focusing, because
The problems such as its component structural complexity, complex manufacturing, high cost, the present invention directly utilizes the stroke post in eyepiece fixed seat
Carry out the focusing of eyepiece with the screw-internal thread fit in focusing handwheel, its structure is simple, easy to operate, production technology simplifies, cost
Low, it is suitable for using on miniscope, adapt to different crowd and use；Spacing catch is used for limiting the shift length of convex lenss,
Ensure that safety.
