Embodiment Construction
[0013] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.
[0014] In the embodiment of the present invention, such as figure 1 As shown, a scope optical axis adjustment mechanism is provided, which includes a hand wheel seat 1, an inner screw 2, a hand wheel 3, a spring 4, a steel ball 5, an inner screw head 6, a pin 7 and a sealing ring 8. The lower part of the handwheel seat 1 is provided with an external thread, and the outside of the handwheel seat 1 is provided with a groove, which cooperates with the sealing ring 8. The inside of the handwheel seat 1 is provided with evenly distributed teeth, and the two slopes of the teeth are tangent to the steel b...

The invention discloses a sighting telescope optical axis adjusting mechanism. The mechanism comprises a hand wheel base, an inner screw, a hand wheel, a spring, a steel ball, an inner screw head anda pin, external threads are arranged on the lower portion of the hand wheel base, evenly-distributed teeth are arranged in the hand wheel base, and the two inclined faces of each tooth are tangent tothe steel ball; internal threads are arranged at the lower part of the hand wheel base and are in threaded connection with the inner screw, and a hole is formed in the upper part of the inner screw and matched with the spring and the steel ball; external threads are arranged at the lower part of the inner screw, part of the threads are in threaded connection with the hand wheel base, and the lowerparts of the threads are in threaded connection with the inner screw head; a groove matched with the pin is formed in the middle of the inner screw; a cylinder is arranged in the hand wheel base, anda hole is formed in the lower portion of the cylinder and matched with the pin; and according to the scheme, different from an existing method for achieving optical axis precision and accidental touch and accidental touch prevention through locking, the pin is driven to be clamped in the inner screw groove when the hand wheel is lifted up, the inner screw is driven to rotate up and down through rotation, and optical axis adjustment is achieved. When the hand wheel is pressed downwards, the pin matched with the hand wheel is separated from the inner screw, and the hand wheel only idles when rotating.
Description
technical field [0001] The invention belongs to the technical field of scope manufacture, and in particular relates to a scope optical axis adjustment mechanism. Background technique [0002] Use scopes to assist shooting on firearms to improve shooting accuracy. The scope is a precision optical instrument, and the optical axis adjustment mechanism is the key to precise adjustment. Considering factors such as misoperation or accidental touch during use, a locking mechanism is usually provided, so the present invention provides a new idea. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a sight optical axis adjustment mechanism to solve the problem of complex and many parts in the existing locking mechanism. The present invention has fewer parts and a larger inner screw head diameter, which is beneficial to large swing angles. The solution of the present invention drives the pin to be stuck in the inner screw gro...
