Description
Technical field
The utility model belongs to optical instrument field, and in particular to a kind of screw thread object lens focusing monocular.
Background technology
Telescope is a kind of visual optical instrument for observing remote object, can be the subtended angle of remote object very little by certain
Multiplying power is amplified, and is allowed to have larger subtended angle in image space, so that the object that with the naked eye can not be seen clearly or differentiate originally is apparent from can
It distinguishes.Therefore, it is indispensable tool in astronomical and ground observation.According to optical element used in telescope, can be classified as
Refracting telescope, reflecting telescope, catadioptric telescope three classes, the telescope in daily life are mostly opening in refracting telescope
General Le telescope, i.e. its object lens and eyepiece are all convex lenses, due to hoping that glasses are visual optical instrument, then require instrument that should be emitted
Directional light is imaged on infinity, that is, it is an afocal system by infinity target imaging in infinity to require telescopic system.
Therefore only with a lens it is inadequate, it is that unlimited far object can be imaged in image space focal plane, it is necessary to along with the
Two lens are imaged on infinity using the picture on its focal plane as the object of second lens, with up to the purpose looked in the distance.Generally
The lens of front are become object lens, subsequent lens are known as eyepiece, in the production of telescope, can add between eyepiece and object lens
Fill a regulating mechanism, to adjust the spacing between eyepiece and object lens, the multiple to improve observation distant place scenery is realized
Clarity, in the prior art, a kind of single-cylinder type telescope, 204347336 U authorized announcement date of Authorization Notice No. CN
2015.05.20, the utility model discloses a kind of single-cylinder type telescope, including outer barrel and inner cylinder, the outer barrel is arranged described
On inner cylinder, both ends are both provided with snap-gauge in the outer barrel cylinder, and the snap-gauge is provided centrally with peep hole, the outer both ends of the internal barrel
It is both provided with snap ring, the outer barrel light input end is provided with connecting cylinder and the outer barrel is connected to one end of the connecting cylinder
On, object lens are provided on the connecting cylinder other end, inner cylinder eyes observation end is provided with eyepiece.The single-cylinder type telescope is logical
The inner cylinder of the setting outer barrel with snap-gauge and band clasp is crossed, inner cylinder can freely stretch in outer barrel, need in use, inner cylinder stretches out
Come, can be very good to observe remote object, do not need and concealed in use, inner cylinder is reduced in outer barrel, it is handy to carry about,
Meanwhile the single-cylinder type telescope configuration is simple, cost is relatively low, cheap, can greatly meet the needs of general public.This is new
Although type inner cylinder can freely stretch in outer barrel, handy to carry about, since inner cylinder and outer barrel use sliding suit
In order to which inner cylinder can be slided smoothly in outer barrel, inherently there is certain gap between barrel when in use in mode,
It gives user's observation in use, light transmission between inner cylinder eyepiece and outer barrel object lens and throw object and will necessarily have certain deviation
Using causing certain inconvenience.
Utility model content
The purpose of the utility model is to overcome the deficiencies in the prior art, provides a kind of screw thread object lens focusing monotubular and look in the distance
Mirror.
In order to reach above-mentioned purpose of design, technical solution is used by the utility model：A kind of screw thread object lens focusing is single
Tube telescope, including eyepiece lens barrel, object lens fixed cylinder, the barrel on the inside of the eyepiece lens barrel object view end are equipped with internal thread, institute
It states and offers ring groove on the barrel in the left side of internal thread, sealing rubber ring is installed in the ring groove, the object lens are solid
The outer wall of safety barrel right end is equipped with to be fixed with the matched external screw thread of barrel internal thread on the inside of eyepiece lens barrel object view end, the object lens
Cylinder spinning is equipped with lightshade cover in the object view end of eyepiece lens barrel, the object lens fixed cylinder left end outer wall.
The lightshade cover is made of flexible material.
The utility model advantageous effect：The pattern of the utility model use combination is by object lens fixed cylinder by screw thread spinning in eyepiece
Inside the object view end of lens barrel, due to being connected by the way of screw thread spinning, when in use, rotation object lens fixed cylinder can be realized pair
The far and near of its object view is adjusted, and is stung jaw between screw thread, is kept it more stable, accurate when adjusting object lens fixed cylinder, and internal thread is left
The sealing rubber ring clamped in side tube-wall ring groove, effectively plays sealing function at it in, avoids dust and marshy land
The inside for entering eyepiece lens barrel ensure that the dried and clean inside eyepiece lens barrel, its telescope is made to use and revolve long-term
Clear smooth under adjusting, this monocular compared with existing monocular, greatly reduces accounting for for space after it is folded
With convenient for the carrying and storage of user.The utility model is simple in structure, operates convenient and efficient, to its object view and micro- scape
Observation it is more stable, due to using screw thread spinning combination, effectively reduce the deviation of light source between eyepiece and object lens.
Description of the drawings
Fig. 1 is a kind of screw thread object lens focusing monocular overall schematic of the utility model.
Specific implementation mode
Specific embodiment of the present utility model is described in detail below in conjunction with the accompanying drawings.As shown in Figure 1：A kind of screw thread
Object lens are focused monocular, including eyepiece lens barrel 1, object lens fixed cylinder 2, on the barrel on the inside of 1 object view end of the eyepiece lens barrel
Equipped with internal thread 3, ring groove 4 is offered on the barrel in the left side of the internal thread 3, is installed in the ring groove 4 close
Sealing rubber ring 5, the outer wall of 2 right end of object lens fixed cylinder is equipped with to be matched with barrel internal thread 3 on the inside of 1 object view end of eyepiece lens barrel
External screw thread 6,2 spinning of object lens fixed cylinder sets on the object view end of eyepiece lens barrel 1,2 left end outer wall of the object lens fixed cylinder
There is lightshade cover 7.
The lightshade cover 7 is made of flexible material.
When the utility model is used:Sealing rubber ring 5 is set in internal thread 3 on the barrel on the inside of 1 object view end of eyepiece lens barrel
Left side ring groove 4 in, then by 2 spinning of object lens fixed cylinder equipped with objective lenses in 1 object view end of eyepiece lens barrel, most
Lens are rotated on inside the right end of eyepiece lens barrel 1 afterwards, when in use, rotating left and right adjusting object lens fixed cylinder 2 can be real
Now to the observation of its object view and micro- scape.
