when the sight has completed the zeroing setting, the compensation mechanism 11 is in the zeroing setting position, as shown in fig. 5A, 5C and 5D, the plug portion 1503 is at the reference position 1105, and the first end 1107 of the circular slot 1102 and the third end 1477 of the limiting groove 1472 are both abutted to the plug portion 1503, the wide portion 1502 abuts against the fifth end 1507 of the sliding groove 1452, and when the adjusting cover 110 starts to be biased from the reset setting position, the adjusting cover 110 is restricted to start to rotate only in one of the clockwise direction and the counterclockwise direction, and after the adjusting cover 110 is separated from the reset setting position, the adjusting cover 110 is not restricted to rotate only in the one direction, and the plug 1503 can move between the first end 1107 and the second end 1109 along the circumferential direction of the annular slot 1102 by rotating the adjusting cover 110. As shown in FIG. 7A, the pin portion 1503 moves along the slot 1102 from a first end 1107 to a second end 1109 by an arc L corresponding to a center of a circle having a first angle θL。
When the latch 1503 moves to abut against the second end 1109 of the annular slot 1102, as shown in fig. 5B, 5C and 5D, the adjustment cover 110 rotates in the direction by the first angle θ relative to the zero-setting positionL(less than one complete turn), while the third end 1477 of the restriction groove 1472 still abuts against the plug portion 1503 and the wide portion 1502 still abuts against the fifth end 1507 of the sliding groove 1452, if the adjustment cover 110 is further rotated in this direction, the second end 1109 of the annular slot 1102 is pushed against the plug portion 1503 to move between the third end 1477 and the fourth end 1479 along the circumferential direction of the restriction groove 1472. As shown in fig. 7B, the pin portion 1503 is pushed to move along the limiting groove 1472 from the third end 1477 to the fourth end 1479 by an arc K corresponding to a second angle θK。
Then, when the second end 1109 of the circular slot 1102 pushes the pin portion 1503 to move along the circumference of the limiting groove 1472 to abut against the fourth end 1479 of the limiting groove 1472, as shown in fig. 6A, 6B and 6C, the second end 1109 of the circular slot 1102 and the fourth end 1479 of the limiting groove 1472 both abut against the pin portion 1503, and the wide portion 1502 abuts against a sixth end 1509 of the sliding groove 1452, at this time, the adjustment cover 110 rotates by the first angle θ in the direction relative to the zero-reset set positionLPlus the second angle thetaK(one complete revolution) while the adjustment cap 110 is thus restrained from further rotation in that direction, the adjustment cap 110 can still be rotated in the opposite direction to that direction. Wherein the first angle thetaLAt the second angle thetaKAfter addingThe angle is 360 degrees, that is, the adjusting cover 110 stops after rotating for one circle in the direction, which is counterclockwise in the present embodiment.
It should be noted that, when the aiming device is to return to the zero setting, the adjusting cover 110 is rotated in the opposite direction until the first end 1107 of the circular slot 1102 and the second end 1477 of the limiting groove 1472 abut against the pin portion 1503 and cannot rotate, and the compensating mechanism 11 returns to the zero setting position.
In addition, when the adjustment cover 110 is restricted and can not rotate in the direction, if the elastic compensation is continued, the adjustment cover 110 can be pulled up to further compress the spring 125, and the adjustment cover 110 is pulled up until the spring 125 is completely compacted and stops, so that the adjustment cover 110 and the connecting piece 135 are released from the interlocking relationship with the adjustment element 120, and the plug 1503 also separates from the annular slot 1102, at this time, the adjustment cover 110 is rotated without driving the adjustment element 120 to rotate, and the plug 1503 does not contact with the first end 1107 or the second end 1109 of the annular slot 1102, then the adjustment cover 110 is rotated to make the plug 1503 locate at a position corresponding to the first end 1107 of the annular slot 1102, the adjustment cover 110 is released, the connecting piece 135 and the adjustment element 120 form the interlocking relationship again by utilizing the restoring force of the spring 125, and the plug 1503 abuts against the first end 1107 of the annular slot 1102, the adjustment cap 110 is thus unrestrained to continue the compensation of the impact.
The compensation mechanism of the sighting device of the invention complements the distance that an annular slot on the inner side of the adjusting cover is not enough to rotate for a circle and a whole through the upper limit groove of the stop unit, and then is matched with the upper plug pin part of the stop unit to ensure that the compensation mechanism is limited to rotate for a circle (360 degrees) after being adjusted for a circle and a whole (360 degrees) in one of the clockwise direction or the anticlockwise direction, in use, the compensation mechanism can rotate a circle (360 degrees) at a time and can continue to rotate after the limitation is removed, the design and operation are more intuitive for users, and the problem that the user usually cannot remember how many turns or how many angles the user has rotated when performing the springing compensation is solved, and in addition, as long as the compensation mechanism is operated in the reverse direction until the compensation mechanism can not rotate any more, i.e., back to the zero set position, the sight can also be easily returned to the zero set position.
