Abstract
The invention relates to an internal rotation type microscopic camera shooting transfer lens with a parfocalization function. The internal rotation type microscopic camera shooting transfer lens comprises an inner barrel, a middle barrel and an outer barrel, the inner barrel, the middle barrel and the outer barrel are sleeved coaxially, a lens is arranged in the inner barrel, the inner barrel and the middle barrel are fixed through a first fastener arranged on the barrel wall of the inner barrel and the barrel wall of the middle barrel in a penetrating mode, one end of the first fastener is exposed out of the middle barrel, a sliding groove extending from one end of the outer barrel to the other end of the outer barrel is formed in the inner wall of the outer barrel, and the exposed end of the first fastener is contained in the sliding groove and can slide along the sliding groove. Due to the fact that the internal rotation type microscopic camera shooting transfer lens adjusts a focal length through the sliding fit of the first screw 4 of the middle barrel 2 and the outer barrel 3 and the sliding groove 5, the sliding groove 5 is formed in the inner wall of the outer barrel 3, the appearance of the product cannot be influenced by exposed threads in the focusing process, focusing can be carried out simply by rotating the outer barrel 3 lightly, and using is very convenient. In addition, a thread fixing section does not need to be arranged, and therefore the adjusting range can be maximized under the condition of the same length.
Description
Technical field
The present invention relates to the optical device field, is a kind of inner-rotary type microimaging switching mirror with parfocalization function specifically.
Background technology
In the micro-imaging field, when observing sample, eyepiece need to realize that focusing is clear by focusing mechanism for microscope.But, camera receive microscopical three order interfaces to focus simultaneously clear could photographic images.This while all needs the action of shape library to be called parfocalization.If destroyed original eyepiece focusing for camera focusing, that will be made troubles to the user, and always switching repeatedly between two kinds of focusings of user also just shows that this microimaging switching mirror does not possess the parfocalization characteristic.So, in order to realize the parfocalization design, microimaging switching mirror must self have focus adjusting mechanism.
In order to realize parfocalization, microimaging switching mirror is all generally that adjusting by two accessory screw threads of outside surface focalizes traditionally, two direct benefits of regulating of accessory screw thread are that processing is simple, but because when an accessory is regulated toward direction, the interior tooth of another accessory will directly be exposed, affect outward appearance, and if it is long that these two accessories of words that adjustable scope is larger will be processed, as adjustable extent is wanted positive and negative 5mm, more than these two accessories will be accomplished 15mm, because except adjustable 10mm, the fixing 5mm left and right of also wanting of tooth.
Summary of the invention
In order to overcome the defect of above-mentioned prior art, technical matters to be solved by this invention be to provide a kind of under equal length the larger inner-rotary type microimaging switching mirror with parfocalization function of adjustable extent.
In order to solve the problems of the technologies described above, the technical solution used in the present invention is:
Inner-rotary type microimaging switching mirror with parfocalization function, comprise the inner core of coaxial socket, middle cylinder and urceolus, be equiped with eyeglass in described inner core, described inner core and middle cylinder fix by first securing member that is arranged in inner core barrel and middle cylinder barrel, one end of described the first securing member exposes the outside of described middle cylinder, offer a chute extended to the urceolus other end by urceolus one end on the inwall of described urceolus, the bared end of described the first securing member is placed in described chute and can slides along chute.
Wherein, described the first securing member is screw, and the spiral shell head of described screw exposes the outside of described middle cylinder.
Wherein, described chute is dovetail groove.
Wherein, described middle cylinder fixes by second securing member that is arranged in middle cylinder barrel and urceolus barrel with urceolus.
Wherein, described the second securing member is screw.
Wherein, an end of described middle cylinder is arranged with set collar, and the other end of described middle cylinder is provided with for connecting the interface of microscope switching cylinder.
Wherein, described chute by urceolus one end to the spiral extension of the urceolus other end.
The present invention compared with prior art, there is following beneficial effect: due to microimaging switching mirror be the first securing member by middle cylinder and urceolus and chute be slidably matched focus, and chute is to be positioned on the inwall of urceolus, therefore in the focusing process, product can not affect outward appearance because thread exposes, during focusing, also only need turn urceolus gently to get final product, very easy to use; In addition, due to without the screw thread canned paragraph is set, therefore can take full advantage of the space of urceolus and middle cylinder, make under equal length, reach the maximization of range of adjustment.

Embodiment
By describing technology contents of the present invention, structural attitude in detail, being realized purpose and effect, below in conjunction with embodiment and coordinate accompanying drawing to be explained in detail.
Refer to Fig. 1 and Fig. 2, the inner-rotary type microimaging switching mirror with parfocalization function of present embodiment, the inner core 1 that comprises coaxial socket, middle cylinder 2 and urceolus 3, be equiped with eyeglass 10 in described inner core 1, eyeglass 10 is pressed in inner core 1 by trim ring 11, described inner core 1 is provided with a threaded hole, be provided with a stopper slot corresponding to described threaded hole place on described middle cylinder 2, described inner core 1 fixes by first screw 4 be tightened in stopper slot and threaded hole to the threaded hole direction by stopper slot with middle cylinder 2, the spiral shell head of described the first screw 4 exposes the outer wall of described middle cylinder 2, offer a chute 5 extended to urceolus 3 other ends by urceolus 3 one ends on the inwall of described urceolus 3, the spiral shell head of described the first screw 4 is placed in described chute 5 and can slides along chute 5.
In the above-described embodiments, described the first screw 4 also can adopt other known securing members, if can realize being connected and fixed inner core 1 with middle 2, and have an end that is exposed to the outer wall of middle 2 and is placed in chute 5 interior slips to get final product.
In the above-described embodiments, described chute 5 is preferably dovetail groove, to play the effect that connects urceolus 3 and middle cylinder 2.
In the above-described embodiments, in order to make urceolus 3 and middle cylinder 2, after focusing completes, fix with each other, described middle cylinder 2 fixes by second screw 6 that is arranged in middle cylinder 2 barrels and urceolus 3 barrels with urceolus 3.Certainly, described the second screw 6 also can adopt other known securing members, as long as can realize fixing middle cylinder 2 and urceolus 3.
