Abstract

The utility model is a diaphragm moving power-changing telescope, which comprises a fixation group, a power-changing group and a compensating group, and is characterized in that: a curve groove is added at the rotating cam so as to insert a diaphragm card into this groove. With regard to this diaphragm moving power-changing telescope, as the diaphragm becomes the moving one and it changes as the change of the power-changing group and the distance between the diaphragm and the power-changing telescope is a moving variable, the diaphragm is at the working state at any time and the reflecting veiling glare can be effectively controlled and the imaging is clearer.

Description

The portable variable power telescope in light hurdle

Technical field

The utility model relates to the portable variable power telescope in a kind of smooth hurdle.

Background technology

Existing telescope (comprise binoculars, monocular and see the telescope etc.) eyepieces that adopt become doubly more.In whole change times process, because of the light hurdle is to be fixed on to become on times group or the compensation group, so when the eyepiece zoom, the light hurdle is fixed with the distance that becomes times mirror, so the light hurdle is only effective in a flash at certain, the eyepiece group is in unglazed hurdle state in the major part time.

Summary of the invention

The purpose of this utility model provides a kind of portable variable power telescope in light hurdle that can solve problems such as becoming times eyepiece image planes are clear, reflection, veiling glare with low cost.

The technical solution of the utility model is: the change times eyepiece component of the portable variable power telescope in light hurdle is fixing group, become doubly group, compensation group; On rotating cam, increase a curved groove (movement locus on light hurdle), make the light hurdle become mobile light hurdle.

The portable variable power telescope in smooth hurdle of the present utility model is because the light hurdle becomes mobile light hurdle, the variation that covariant is doubly organized and correspondingly changing, making light hurdle and the distance that becomes times eyepiece is the variable of a motion, thereby it is all in running order in institute is free to reach the light hurdle, the reflection veiling glare is effectively controlled, and imaging is more clear.

Among the figure, 1-fixing group, 2-become doubly and organize 3-compensation group, 4-cam, 5-mobile light hurdle, 6-curved groove, 7-curved groove.

Embodiment

Embodiment: as shown in Figure 3, Figure 4, the portable variable power telescope in smooth hurdle of the present utility model comprises fixing group 1, become doubly organize 2, compensation group 3, on rotating cam 4, increase a curved groove 7 (as Fig. 5, shown in Figure 6), the track of curved groove 7 changes principle by focal plane in the optics and determines, guide pin on the light hurdle group is stuck in this groove, the light hurdle moves in this track, makes the light hurdle become mobile light hurdle.

When cam rotates, become group doubly just the curved groove on the cam upwards (downwards) move, also upwards (downwards) motion of the curved groove on the cam of mobile light hurdle, compensation group be upwards (downwards) motion of curve on the cam also, makes the light hurdle all in running order in if having time.

Claims

1, the portable variable power telescope in a kind of smooth hurdle comprises fixing group, becomes doubly group, compensation group, it is characterized in that increasing a curved groove on rotating cam, and Jiang Guanglan is stuck in this groove.
