Embodiment
As Fig. 1, shown in Figure 2, this binocular telescope, comprise and be built-in with object lens 1 respectively, eyepiece 2, first lens barrel 4 of prism 3 and second lens barrel 5, transfer pupil device 6, transfer pupil device 6 to comprise and transfer pupil bar 601, first tooth bar 602, the gear 603 and second tooth bar 604, first lens barrel 4 and second lens barrel 5 are connected the two ends of transferring pupil device 6, first lens barrel 4 and second lens barrel 5 are symmetrical structures, first lens barrel 4 and second lens barrel 5 are arranged on by coupling arrangement 7 respectively and transfer on the pupil bar 601, one end of first tooth bar 602 and second tooth bar 604 is fixedlyed connected with second lens barrel 5 with first lens barrel 4 respectively, the other end of first tooth bar 602 and second tooth bar 604 is meshed with the both sides of gear 603 respectively, described gear 603 is arranged to be transferred on the pupil bar 601 by in the formed inside groove 605 of open-work, described first tooth bar 602 and second tooth bar 604 also are arranged in the inside groove 605, leave the gap between first tooth bar 602 and second tooth bar 604 and the inside groove 605.When clockwise rotating gear, drive first tooth bar 602 and second tooth bar 604 that are connected on first lens barrel 4 and second lens barrel 5 and move inward synchronously, this moment, interpupillary distance reduced; When rotating counterclockwise gear constantly, first tooth bar 602 and second tooth bar 604 outwards move synchronously, and this moment, interpupillary distance increased.
Eyepiece 2 by the external thread on its eyepiece mount 9 respectively with first lens barrel 4 and second lens barrel, 5 internal thread threaded engagement, end the aperture threaded engagement of offering on spiral shell device 12 and the lens barrel mouth, ending spiral shell device 12 is screws, when rotation eyepiece mount 9 is focused, eyepiece mount 9 is understood when eyepiece 2 relative object lens 1 are in distal-most end and the outstanding lens barrel mouth inner wall part phase-splitting card of screw, and this moment, eyepiece mount 9 was in rotatable extreme position.
The maximum outside diameter of first lens barrel 4 and second lens barrel 5 is 55mm, the effective aperture of built-in object lens 1 is 50mm, the range of adjustment that so just can realize two eyepiece eye-distances is 55mm-74mm, and eyepiece 2 is 19 ° with the maximum field of view angle that object lens 1 constitute, and watches field angle to enlarge thereby make.
In the binocular telescope illustrated in figures 1 and 2, any can also be fixedlyed connected with accent pupil bar 601 and become one in first tooth bar 602 or second tooth bar 604, or constitute by the teeth of on inside groove 605, being processed.When transmitting gear 603, when driving first tooth bar 602 be connected on first lens barrel 4 and second lens barrel 5 and second tooth bar 604 and moving inward, interpupillary distance is dwindled; First tooth bar 602 or second tooth bar 604 are outside when mobile, and interpupillary distance increases.
In the binocular telescope shown in Figure 1, but end spiral shell device 12 can also by be arranged on lens barrel mouth inwall and eyepiece mount 9 outer walls respectively, the projection of clamping cooperation when eyepiece 2 relative object lens 1 are in distal-most end constitutes, such projection can be convex edge or boss.When 9 focusing of rotation eyepiece mount, be in the distal-most end place at eyepiece 2 relative object lens 1, projection clamping mutually on lens barrel mouth inwall and eyepiece mount 9 outer walls, this moment, eyepiece mount 9 rotated to extreme position, had so just prevented that eyepiece mount 9 from excessively causing optical element to unload taking off or fall on the ground impaired because of rotating.
In the binocular telescope shown in Figure 1, leave the gap between first tooth bar 602 and second tooth bar 604 and the inside groove 605, preferably contact matching also can be to be slidingly matched, and it can be slided along the adjusting direction of transferring pupil bar 601.
Shown in Fig. 3 (a), coupling arrangement 7 is preferably slide block 701, slide block 701 is embedded in the inside groove 605, can slide along regulating direction, and this slide block 701 is provided with bearing pin 8, one end of this bearing pin 8 is connected with lens barrel by transferring pupil bar 601, the other end is provided with the end cap of diameter greater than inside groove 12 width, when transmitting gear 603 is regulated interpupillary distance, unclamps bearing pin 8, slide block 701 can horizontally slip along regulating direction under the drive of gear 603, till human eye sees that complete closing resembles; Can utilize bearing pin 8 fixing and lockings after adjusting is finished, make slide block 701 move left and right again, the center interpupillary distance just is fixed up like this.
Shown in Fig. 3 (b), coupling arrangement 7 can also be sliding sleeve 702, sliding sleeve 702 is to be socketed on to transfer on the pupil bar 601, this sliding sleeve 702 is and the closed-in construction of transferring pupil bar 601 to be slidingly matched, this structure can be sealed, also can be semi-enclosed, when transmitting gear 603 was regulated, driving sliding sleeve 702 can move left and right.
Fig. 4 is another optimal way of the accent pupil device of binocular telescope shown in Figure 1, is characterised in that: gear 603 is arranged on the back up pad 10 of transferring pupil bar 601 centers.The thickness of back up pad 10 is generally less than the thickness of transferring pupil bar 601, and back up pad 10 is embedded in the inside groove.Back up pad 10 is fixedlyed connected with transferring pupil bar 601, offers open-work 11 on the back up pad 10.One end of gear 603 wheel shafts passes the open-work 11 on the back up pad 10, and the other end of gear 603 is meshed with first tooth bar 701 and second tooth bar 702 respectively.The wheel shaft of gear 603 can rotate with respect to open-work 11.When clockwise rotating gear 603, wheel shaft one end of gear 603 rotates with respect to clockwise back up pad 10, the other end of gear 603 drives first tooth bar 602 and second tooth bar 604 that are connected on first lens barrel 4 and second lens barrel 5 and moves inward synchronously, and this moment, interpupillary distance reduced; When rotating counterclockwise gear 603, wheel shaft one end of gear 603 rotates with respect to clockwise back up pad 10, the other end of gear 603 drives first tooth bar 602 and second tooth bar 604 that are connected on first lens barrel 4 and second lens barrel 5 and outwards moves synchronously, and this moment, interpupillary distance increased.Adopt such structure to make and transfer the globality of pupil device 6 better, precision is higher.
Above-mentioned binocular telescope is not limited to the above-mentioned telescope that is built-in with prism, also comprises the Galileo telescope of no prism.
Above-mentioned binocular telescope has not only adopted gear, rack mechanism to regulate interpupillary distance, also is provided with the scale mark of indicating the center interpupillary distance, therefore can also use as an accurate interpupillary distance surveying instrument.
