Description

Technical Field

[0001] The present application relates to the technical field of sights, and in particular to a sight zoom device. Background Art

[0002] A scope, or optical sighting device, is an optical sighting device used for firearms. Its main function is to help the shooter accurately aim at the target. Scopes are mainly divided into the following three categories: telescopic sights, collimating sights, and reflex sights.

[0003] One type of currently used adjustable focus sight is to focus by means of objective lens focusing, but this objective lens focusing device is at the front end of the sight, far from the shooter, and is inconvenient to adjust, and it is impossible to focus while observing, which reduces the practicality of the objective lens focusing sight to a certain extent. Another type is to adjust the focal length by adjusting the focusing hand wheel on the left side of the lens tube to drive the internal focusing optical lens to move, but the existing left-side focusing sight requires the shooter to hold the gun with the right hand and adjust the focusing hand wheel with the left hand, which is very inconvenient for some shooters who hold the gun with the left hand and can only focus with the right hand, and cannot focus while aiming. Summary of the invention

[0004] In order to solve the problems raised in the above background technology, the purpose of the utility model is to provide a sight zoom device that can be easily adjusted by all shooters, whether they are accustomed to holding the gun with their left hand or right hand.

[0005] In order to achieve the above objectives, this application provides the following technical solutions:

[0006] A zoom device for a sighting scope comprises: a focusing hand wheel and a focusing lens group, wherein the focusing hand wheel is arranged at the upper middle part of a scope tube, the focusing hand wheel is used to adjust the focusing lens group, and a ballistic adjustment hand wheel and a wind direction adjustment hand wheel are arranged outside the sighting scope;

[0007] The focusing hand wheel is located at the lower part of the ballistic adjustment hand wheel above the mirror tube, an adjustment wheel is arranged on the outside, a curve wheel is arranged below the adjustment wheel, and a sliding rod is arranged inside the curve wheel; the focusing lens group is located inside the mirror tube, connected to the focusing lens frame by a sliding rod, and the focusing lens frame has a built-in focusing lens.

[0008] The adjusting wheel is punched with internal teeth to match the external teeth of the curve wheel and connected by a fixing piece;

[0009] Optionally, the fixing member is a tip set screw, and the tip set screw passes through the inner side of the adjusting wheel and then presses the curve wheel.

[0010] The curve wheel is locked on the mirror tube by a curve wheel pressure ring; an Archimedean spiral groove is arranged in the curve wheel.

[0011] Optionally, the curve wheel pressing ring is made of aluminum alloy material, and is screwed together with the thread on the mirror tube to tighten the curve wheel.

[0012] A sealing ring is arranged between the curve wheel and the curve wheel pressure ring.

[0013] Optionally, the sealing ring is made of oil-resistant nitrile rubber.

[0014] The lower part of the sliding rod is provided with a threaded connection focusing lens frame, and the upper part is placed in the Archimedean spiral groove of the curve wheel. When the curve wheel rotates, the sliding rod is driven to perform linear motion.

[0015] The focusing lens is fixed in the focusing lens frame by glass glue.

[0016] Optionally, the adjusting wheel is made of aluminum alloy and has a three-claw shape.

[0017] Compared with the prior art, this application has at least the following beneficial effects:

[0018] 1. The present application provides a zoom device for a scope, including: a focusing hand wheel and a focusing lens group. The focusing hand wheel is integrated below the ballistic adjustment hand wheel and is arranged on the upper part of the scope tube. An adjustment wheel is arranged outside. A curve wheel is connected below the adjustment wheel. A sliding rod is arranged in the Archimedean spiral groove on the curve wheel. One end of the sliding rod is connected to the focusing transparent frame. The rotation of the curve wheel drives the focusing lens connected to the sliding rod to move linearly to achieve zooming. The present application has a simple structure and is easy to operate. The shooter can focus easily and quickly with either the left or right hand.

[0019] 2. The adjusting wheel of the present application is a three-claw structure, which is light in weight and easy to adjust. BRIEF DESCRIPTION OF THE DRAWINGS
