At this time, the locking ring presses the locking ball tightly between the teeth through the locking spring and the positioning pin, so that the adjusting hand wheel cannot be rotated. When the regulating screw set needs to be unlocked, the locking ring is rotated so that the arc-shaped groove part aligns with the locking hole. At this time, the locking ball can move back and forth between different teeth, so that the adjusting hand wheel can be freely rotated.

The periodic clamping teeth on the positioning gear ring in the locking assembly are in precise cooperation with the locking ball, the positioning pin and the locking spring. When the adjusting hand wheel rotates, the locking ball orderly moves between the clamping teeth, not only makes the adjusting process have clear gear feedback, but also realizes the controllability of the adjusting precision through the periodic distribution of the clamping teeth, effectively improves the precision of the sighting scope adjustment, and meets the high-precision use requirement. The arc-shaped groove design on the inner side of the locking ring cooperates with the through locking hole on the hand wheel pressing ring, and only needs to rotate the locking ring to realize the quick switching of the unlocking and the locking. When unlocking, the arc-shaped groove is aligned with the locking hole, the locking ball can freely move to ensure the flexible rotation of the adjusting hand wheel. When locking, the non-arc-shaped groove part presses the positioning pin and the locking spring, so that the locking ball is tightly clamped between the clamping teeth, and a reliable self-locking effect is formed. Even if the sighting scope is subjected to external force such as vibration, the adjusting parameter will not be deviated, completely solves the problems that the traditional sighting scope adjusting mechanism lacks reliable self-locking and is easy to change the parameter due to external force, considers the convenience of the adjustment and the stability in the use process, and significantly improves the use reliability and the aiming precision of the sighting scope.

DETAILED DESCRIPTION

[0017] In order to make the objects, technical solutions and advantages of the embodiments of the present disclosure clearer, the technical solutions of the embodiments of the present disclosure will be described clearly and completely below with reference to the drawings of the embodiments of the present disclosure.

The locking assembly comprises a positioning gear ring 507, a positioning pin 509, a locking spring 511, a locking ball (a steel ball 510 in the embodiment), and a locking ring. The locking ring is sleeved outside the hand wheel pressing ring 504, the inner side of the locking ring is provided with an arc-shaped groove, the positioning pin 509 is arranged in the locking hole, the locking spring 511 is connected to one end of the positioning pin 509 close to the locking ring, the locking ball is connected to one end of the positioning pin 509 close to the positioning gear ring 507, the positioning ring is fixed to the circumferential side of the inner adjusting handle 508, and the positioning gear ring 507 is periodically provided with a tooth. When the adjustment screw set 5 needs to be locked, the locking ring is rotated so that the non-arc groove part aligns with the locking hole, at this time the locking ring presses the locking ball between the teeth by the locking spring 511 and the positioning pin 509, so that the adjustment hand wheel cannot be rotated; When the adjustment screw set 5 needs to be unlocked, the locking ring is rotated so that the arc groove part aligns with the locking hole, at this time the locking ball can move back and forth between different teeth, so that the adjustment hand wheel can be freely rotated (at the same time, due to the movement of the locking ball in the teeth, the adjustment hand wheel will produce a gear feeling when rotating).

[0019] Specifically, the adjustment screw 502 acts on the reticle of the scope, and is used to adjust the vertical and horizontal positions of the reticle, so as to realize the adjustment of the ballistic and windage of the scope. The hand wheel pressing ring 504 is connected with the hand wheel seat 501 through the screw 513.

[0020] Further, the bottom of the adjustment screw 502 is connected with the gasket 503.

[0021] Further, the locking ring comprises a locking hand wheel 505 and a locking inner liner 506, the locking inner liner 506 is fixed to the inner side of the locking hand wheel 505, and the arc groove is arranged on the inner side of the locking inner liner.

[0023] Further, the positioning tooth ring 507 is provided with 80 teeth, and each tooth corresponds to an adjustment accuracy of 0.05 mrad of the scope.

[0024] Referring to Figure 3 , the embodiment also discloses a scope, which comprises a mirror body 7, an objective lens group 1, a focusing lens group 4, a relay lens group 3, an ocular lens group 2 and a pair of adjustment screw sets 5 described above.

The relay first glue lens 303 and the relay third lens 304 constitute a variable magnification group, and the relay second glue lens 305 constitutes a compensation group.

[0026] Specifically, when the magnification of the sighting telescope changes from high to low, the combined magnification of the system will change when the variable magnification group moves along the optical axis, and the image of the variable magnification group will also move. In order to keep the image plane of the system stationary, the compensation group moves according to a certain rule at the same time as the variable magnification group moves, so that the image point of the variable magnification group still stays in the original position after passing through the compensation group. The movement rule of the variable magnification group and the compensation group is nonlinear, and the movement relationship between the two is calculated by Newton's law (the structure design that causes the variable magnification group and the compensation group to cooperate with each other is a conventional setting in the field, and will not be described in detail in this embodiment). The light passes through the relay lens group 3 to form an image on the second image plane, and then passes through the eyepiece group 2 to exit as parallel light, forming an image on the retina. In this embodiment, the distance between the front field lens 302 and the reticle is reduced to 5mm, which improves the reticle adjustment range of the product. The variable magnification group is composed of a double-convex lens and a double-convex lens, which increases the main surface distance between the front field lens 302 and the variable magnification group to more than 10mm. The focusing range of the focusing lens 401 in the focusing lens group 4 is 0-3.1mm. The system uses a double-convex lens for the rear field lens 306, which reduces the system aberration. The distortion under each magnification is less than 3%, and the image is not significantly distorted. The spherical aberration, axial chromatic aberration, and sinusoidal aberration of the optical system are all less than λ / 4 (λ is the wavelength), which meets the imaging standard.

[0027] Further, the rear field lens 306 is a double-convex lens.

[0029] Further, the relay lens group includes a tightening screw 314; after the parallax correction is completed, the tightening screw 314 fixes the relay lens body 311 and the fixed joint 313.

[0030] Further, it includes a support group 6; the sighting telescope is connected with the external structure through the support group 6.
