Description

A kind of telescope ocular regulating mechanism

Technical field

The utility model belongs to optical instrument field, and in particular to a kind of telescope ocular regulating mechanism.

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, it is existing in Assembling Production when, a groove is opened up on the outer wall of eyepiece fixed cylinder usually in lens barrel, is needed mesh Groove on the outer wall of mirror fixed cylinder is rotated to the opening position of lens barrel outer wall to be inserted into adjustable plate on the outer wall of eyepiece fixed cylinder again Groove in, then by spinning regulation stud its adjustable plate is fixed, it is comparatively laborious, i.e., it is time-consuming and laborious, reduce dress With production efficiency.

Utility model content

The purpose of the utility model is to overcome the deficiencies in the prior art, provide a kind of telescope ocular regulating mechanism.

In order to reach above-mentioned purpose of design, technical solution is used by the utility model：A kind of telescope ocular adjusting Mechanism, including lens barrel, eyepiece fixed cylinder, the lens barrel outer wall are equipped with symmetrical adjusting ear mount, the adjusting ear mount top Equipped with regulation stud, the regulation stud left end is equipped with regulation handle, and adjustable plate, the tune are installed in the middle part of the regulation stud It is equipped with through-hole in the middle part of fishplate bar, is set with guide post in the through-hole, is equipped with and guide post both ends on the adjusting ear mount inboard ear wall Matched card slot, it is described adjust ear mount between lens barrel outer wall on offer gap, being set with eyepiece in the lens barrel fixes Cylinder, the eyepiece fixed cylinder right end outer wall is offered to be clamped with the matched ring-like card slot of adjustable plate, the bottom end of the adjustable plate In in the ring-like card slot on the eyepiece fixed cylinder right end outer wall.

The utility model advantageous effect：Traditional assembly method is changed, the utility model passes through spinning in the middle part of regulation stud Adjustable plate and the guide post for adjusting suit in the middle part of fishplate bar, quickly clamp fixation, and realize that eyepiece is fixed by the eyepiece fixed cylinder in lens barrel Cylinder bilateral reciprocation in lens barrel, to play the distance and size that adjust object view.The utility model is simple in structure, assembling and It is convenient and efficient when replacement accessory, effectively raise Assembling Production efficiency.

Description of the drawings

Fig. 1 is a kind of telescope ocular regulating mechanism 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：One kind is looked in the distance Mirror eyepiece regulating mechanism, including lens barrel 1, eyepiece fixed cylinder 2,1 outer wall of the lens barrel are equipped with symmetrical adjusting ear mount 3, institute It states and adjusts the top of ear mount 3 and be equipped with regulation stud 4,4 left end of the regulation stud is equipped with regulation handle 4.1, in the regulation stud 4 Portion is installed with adjustable plate 5, and 5 middle part of the tune fishplate bar is equipped with through-hole, is set with guide post 6 in the through-hole, in the adjusting ear mount 3 Pick up the ears to be equipped on wall with the matched card slot 7 in 6 both ends of guide post, offer on 1 outer wall of lens barrel adjusted between ear mount 3 open-minded Mouthfuls 8, eyepiece fixed cylinder 2 is set in the lens barrel 1, and 2 right end outer wall of the eyepiece fixed cylinder is offered to be matched with adjustable plate 5 Ring-like card slot 9, the bottom end of the adjustable plate 5 is installed in the ring-like card slot 9 on 2 right end outer wall of the eyepiece fixed cylinder, institute It states eyepiece fixed cylinder 2 and bilateral reciprocation is realized by the adjustable plate in regulation stud 4.

When the utility model is used:The top that will regulation stud 4 rotation and adjust ear mount 3, while spinning, by adjustable plate 5 need spinning between so that the position of adjustable plate 5 is in adjusting ear mount 3 symmetrical on 1 outer wall of lens barrel, then Guide post 6 is set in the through-hole at 5 middle part of adjustable plate, after, the eyepiece fixed cylinder 2 being equipped with is set in the mesh of lens barrel 1 Mirror end, promotion eyepiece fixed cylinder 2 make to open on 1 outer wall of lens barrel that the ring-like card slot 9 on right end outer wall is exposed between adjusting ear mount 3 If gap 8 at, then rotate regulation stud 4 on adjustable plate 5, so that 5 bottom end of adjustable plate is stuck in 2 right end outer wall of eyepiece fixed cylinder On ring-like card slot 9 in, and 6 both ends of guide post at the middle part of adjustable plate 5 are installed in adjust on 3 inboard ear wall of ear mount and guide post 6 respectively In the matched card slot in both ends 7, you can bilateral reciprocation of the eyepiece fixed cylinder 2 in lens barrel 1 is realized, to play instrumentality The distance and size of scape.
