Description
Technical field
The present invention relates to a kind of telescope focusing structure, is specifically a kind of binoculars focusing structure.
Background technology
Telescope is a kind of optical instrument that remote object is observed using lens or speculum and other optics, is wrapped
Include binoculars and monocular.The focusing structure of existing binoculars includes focusing screw and focusing lens, passes through
The focusing screw being inserted into lens barrel drives focusing lens in lens barrel intrinsic displacement, so that the spacing for adjusting focusing lens and eyepiece is realized
The focus adjustment of telescope.Connective stability is poor between the component of this structure, and easily by extraneous factor, (shake, stir tune for a long time
It is burnt spiral etc.) the optical axis accuracy of focusing lens is destroyed, influence the normal use of telescope；It is raw meanwhile this Standard is complicated
Produce of high cost.
The content of the invention
The technical problems to be solved by the invention are to provide a kind of simple in structure, stabilization, and easy to assembly, production cost is low
Binoculars focusing structure.
The technical solution that the present invention solves above-mentioned technical problem is as follows：In a kind of binoculars focusing structure, including band
The shank of axis, a pair of of objective tube and the object lens being located at respectively in a pair of objective tube, further include focusing handwheel, with externally threaded
Focusing pipe, two drive links and two slide cartridges and the focusing lens being respectively fixedly disposed in two slide cartridges, the tune
One end of burnt pipe is fixedly connected with the focusing handwheel, the other end one end of its axis away from the object lens corresponding with the shank
It is threadedly coupled, in one end insertion focusing pipe of the axis away from the object lens of the shank；
The both sides that the back of the shank or belly correspond to its axis offer sliding slot respectively, and the sliding slot is in the shank
On extend along the length direction of the objective tube, two drive links are respectively in the corresponding sliding slot and can be along correspondence
The sliding slot extending direction slide, the every one end of the drive link away from the object lens to it is described focusing pipe bending and with
The focusing pipe is flexibly connected, and the every drive link is with the focusing pipe disengaging shank and in the corresponding sliding slot
The interior extending direction along the sliding slot reciprocatingly slides；
Two slide cartridges can slide in two objective tubes and in the corresponding objective tube respectively, two
A objective tube offers straight slot, length side of the straight slot along the objective tube close to the side of the corresponding drive link
To extension, the every drive link is fixedly connected close to one end of the object lens with a connecting rod, and the connecting rod passes through corresponding
The straight slot is removably connected with the slide cartridge, the displacement with the displacement of the corresponding drive link of each slide cartridge.
Operation principle：Focusing handwheel described in positive and negative rotation drives the focusing pipe to pass in and out the shank, the drive link with
The focusing pipe passes in and out the shank and shift reciprocately, the slide cartridge are reciprocal with the drive link in the corresponding sliding slot
Displacement and shift reciprocately, the focusing lens change and hope with the shift reciprocately of the slide cartridge in the corresponding objective tube
The distance between remote mirror eyepiece, realizes focusing.
The beneficial effects of the invention are as follows：Since the focusing lens is fixed in the slide cartridge, and with the slide cartridge
Focusing is realized in the objective tube intrinsic displacement, it is simple in structure, stable；Since the focusing pipe uses spiral shell with the shank
Line connects, and the focusing pipe is flexibly connected with two drive links, and the drive link is removably connected with the slide cartridge, and two
Drive link described in root can slide in the corresponding sliding slot and along the extending direction of the corresponding sliding slot respectively, therefore assemble
Convenient, production cost is low.
Further, the described one end of focusing pipe away from the focusing handwheel is fixedly installed connection tubing string, the shank
Axis is focused in pipe through the connection tubing string insertion is described, and the connecting tube column outer wall circumferentially offers annular groove, two institutes
State one end away from the object lens of drive link to be inserted into the annular groove, and rotate cooperation with the connection tubing string, by institute
One end away from the object lens of drive link is stated to be inserted into the annular groove and rotate cooperation with the connection tubing string, therefore described
When pipe of focusing passes in and out the shank with the focusing handwheel positive and negative rotation, the rotation of the connection tubing string will not drive the transmission
Bar rotates, but it can drive the drive link in the sliding slot along the sliding slot with the axial displacement that the focusing pipe produces
Extending direction displacement, realizes that two drive links are flexibly connected with the focusing pipe, and simple in structure, and reliability is high, dress
With convenient.
Further, to be fixedly installed covering respectively corresponding described for the position of corresponding two drive links on the shank
The cover board of drive link, using the cover board ensure the drive link will not because extraneous factor or telescope itself focusing action and on
Lower swing.
Further, hole for injecting glue is offered on the cover board, freezing plastic is marked with the hole for injecting glue, the cover board passes through described
Freezing plastic is glued fixed with the shank, improves the reliability that the cover board is fixedly connected with the shank.
Further, the freezing plastic is belt glue, and cover board described in the raising solidification glue glued adhesion is reliable with the shank
Property.
Further, front end limit is fixedly installed respectively along the extending direction both sides of the sliding slot among the sliding slot bottom wall
Position column and rear end limited post, offers the spacing straight slot of up/down perforation on the drive link, and the spacing straight slot is along the object lens
The extending direction extension of cylinder, it is saturating to limit the focusing that the front end limited post and rear end limited post both pass through the spacing straight slot
Mirror maximum focussing distance and minimum focussing distance, determine the focusing range of telescope, avoid user from arbitrarily focusing and cause to hope
The focusing structure of remote mirror is destroyed, and the drive link is carried out using the front end limited post and rear end limited post in assembling
Assembling is accurately positioned, improves efficiency of assembling.
Further, the sliding slot opens up jagged close to one end of the object lens close to the side wall of the objective tube, right
Connecting hole is offered on the slide cartridge barrel answered, the connecting rod is inserted into the connecting hole through the notch can with the slide cartridge
The connection of dismounting, realizes that the connecting rod is removably connected with the slide cartridge, while more conducively described drive link and the slide cartridge
Assembling.
