Gear-driven adjusting hand wheel mechanism

Abstract

The invention discloses a gear-driven adjusting hand wheel mechanism and aims at providing a gear-driven adjusting hand wheel mechanism which can perform fine and precise adjustment and improve shooting accuracy greatly. The gear-driven adjusting hand wheel mechanism comprises an adjusting hand wheel (3), an adjusting screw (17), an adjusting screw seat (22), an adjusting screw head (20), an adjusting screw locking cover (10) and a gear driving device arranged between the adjusting hand wheel (3) and the adjusting screw (17). The adjusting screw (17) is rotatably arranged inside the adjusting screw seat (22), the adjusting screw locking cover (10) presses the adjusting screw (17) and is fixedly matched with the adjusting screw seat (22), the adjusting screw head (20) is arranged inside the adjusting screw (17) and threadedly matched with the adjusting screw (17), and the bottom of the adjusting screw head (20) penetrates a non-circular hole in the adjusting screw seat (22) and is in a clearance fit with the non-circular hole. The gear-driven adjusting hand wheel mechanism can be widely applied to the field of sighting telescope.

[0002] Sights are often used as an auxiliary aiming tool in firearms. The existing sights generally use an adjustment handwheel mechanism to adjust the reticle. In the past, the internal adjustment nails of the adjustment handwheel mechanism directly cooperate with the reticle lens holder or the differentiation plate. , when correcting, due to the rotation of the adjustment nail at the intersection of the adjusting nail and the reticle mirror base or the differentiation plate, the peripheral surface of the reticle mirror base or the differentiation plate is greatly worn, and dust is likely to be generated, and the direct consequence is to cause Calibration is not easy to achieve, the accuracy of calibration is low, and the time required for calibration increases. The user is inconvenient to use and the sight is eliminated prematurely, which shortens the service life of the sight. Therefore, Patent No. 201020513676.8 provides an adjustment handwheel mechanism, the adjusting handwheel mechanism includes a handwheel seat, an adjusting nail, an adjusting nail head, and an adjusting nail locking cover. The seat is fixed and fit, the top of the adjusting nail passes through the locking cover of the adjusting nail, the head of the adjusting nail is placed inside the adjusting nail and fits with the thread of the adjusting nail, the head of the adjusting nail passes through the hole on the hand wheel seat and fits with the hole gap , adjust the nail head to be non-cylindrical. This method can solve the above problems. However, such a structure cannot achieve fine adjustment and fine adjustment, and cannot ensure that the reticle center is aligned with the target, which affects the shooting. accuracy
