Description
Technical field
The utility model is related to microscope technology field, more particularly to a kind of binocular lens tube interpupillary distance regulating device
Background technology
Binocular lens tube is the important component of Optics in Microscope observing system, generally by zooming system interface, left and right
Several parts such as barrel assembly and eyepiece are formed.In actual use, user needs to pull the spacing of both left and right lens barrel adjustment, so that
The interpupillary distance (abbreviation interpupillary distance) of the centre distance and user of two groups of eyepieces on the lens barrel of left and right itself matches, generally
For, user needs to realize matching by repeated multiple times adjustment.In order to facilitate the operation of user, the binocular of some products
Lens barrel, if user has known the interpupillary distance of oneself in advance, can directly pull a left side in shell surface marking interpupillary distance registration
Right lens-barrel greatly facilitates the operation of interpupillary distance adjusting to interpupillary distance registration marker location.But in many cases, these are so-called
The precision of interpupillary distance registration is not very high, even if lens barrel is adjusted in place by user by the mark of interpupillary distance registration, it is still necessary to left and right mirror
Cylinder, which carries out subtle adjustment several times, could obtain the interpupillary distance of oneself needs.
Utility model content
Precision for above-mentioned existing microscopical interpupillary distance registration is not very high, even if user will by the mark of interpupillary distance registration
Lens barrel is adjusted in place, it is still necessary to which subtle adjustment several times is carried out to left and right lens barrel could obtain the interpupillary distance problem of oneself needs, this reality
It is to provide a kind of binocular lens tube interpupillary distance regulating device with new technical problems to be solved.
In order to solve the above technical problems, the technical solution of the utility model is：A kind of binocular lens tube interpupillary distance regulating device, bag
Include left adjusting knob, adjusting rod, left swivel nut, left swivel nut seat, right swivel nut, right swivel nut seat, right adjusting knob, left lens barrel and right mirror
Cylinder, the left swivel nut, right swivel nut and adjusting rod pass through the threaded connection being arranged on left swivel nut, right swivel nut and adjusting rod, institute
It states left swivel nut and right swivel nut is respectively installed on left swivel nut seat and right swivel nut seat, the left swivel nut seat and right swivel nut seat are fixed respectively
To on left lens barrel and right lens-barrel, and form rigid connection.
The preferred embodiment of said program is：The screw thread of the left swivel nut, right swivel nut and adjusting rod is one start screw or bull
Screw thread, and form screw pair.
The preferred embodiment of said program is：The left swivel nut with being both provided with screw thread and oppositely oriented on right swivel nut, and with
Adjusting rod constitutes a pair of incorgruous screw pair.
The preferred embodiment of said program is：It is carved with instruction baseline in the adjusting rod surface.
The preferred embodiment of said program is：The right swivel nut seating face is carved with interpupillary distance registration.
The utility model compared with prior art, has the advantages that：
1st, it is simple in structure, it is easy for installation：The utility model drives left and right lens barrel close and beats using incorgruous screw pair
It opens, so as to fulfill fine-tuning for interpupillary distance, whole device structural member is few, and structure composition is extremely simple, installs and uses also extremely square
Just.
2nd, convenient for the upgrading of product：Do not possessed the binocular lens tube of interpupillary distance regulating device originally for some, and only needed letter
Single transformation can upgrade to the binocular lens tube with interpupillary distance regulating device, and upgrading cost is relatively low, has great convenience for the user.
3rd, degree of regulation is high：Due to the drive motion pair adjusted using screw pair as interpupillary distance, so only needing to control
The machining accuracy of mechanical structured member, you can obtain higher interpupillary distance display precision.
Description of the drawings
Fig. 1 is a kind of structure diagram of binocular lens tube interpupillary distance regulating device of the utility model.
In figure：The left adjusting knobs of 1-, 2- adjusting rods, the left swivel nuts of 3-, the left swivel nut seats of 4-, the right swivel nuts of 5-, the right swivel nut seats of 6-, 7-
Right adjusting knob, the left lens barrels of 8-, 9- right lens-barrels, 10- interpupillary distance registrations, 11- instruction baselines.
Specific embodiment
Specific embodiment of the present utility model is described further below in conjunction with the accompanying drawings.It should be noted that
It is used to help understand the utility model for the explanation of these embodiments, but does not form the restriction to the utility model.This
