Description

Technical Field

[0001] The utility model relates to the technical field of optical sights, in particular to an optical sight with excellent focusing performance. Background Art

[0002] An optical sight is a device that uses an optical lens to form an image. Its main function is to overlap the target image and the aiming line on the same focal plane, so that even if the eye is slightly offset, it will not affect the aiming point. Optical sights can usually magnify the image multiples, and are divided into two categories: fixed multiples and adjustable multiples. For example, 4x28 refers to a sight with a 28mm objective lens diameter and a fixed magnification of 4x, while 3-9x40 refers to a sight with a 40mm objective lens and an adjustable magnification from 3x to 9x. This device is widely used in military and sports shooting fields to help shooters accurately aim at targets in various environments.

[0003] At present, the focal length of a low-light optical sight is mainly adjusted by adjusting the position of the objective lens group to ensure a clear target image. During adjustment, the focusing operation is usually performed by rotating the focusing hand wheel at the objective lens group. However, due to manual adjustment, the adjustment range is large during the adjustment process. A slight effort will cause the focusing hand wheel to rotate a large angle, making it difficult to make fine adjustments, making the focal length adjustment inconvenient. Therefore, an improvement is proposed. Utility Model Content

[0004] The utility model is to solve the shortcomings in the prior art and to provide an optical sight with excellent focusing performance.

[0005] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: an optical sight with excellent focusing performance, comprising a sight body and a focusing hand wheel installed on the sight body, one side of the outer surface of the sight body is fixedly connected to a shell, one side of the outer surface of the shell is provided with a knob, one end of the knob is installed with a pinion drive assembly, and the outer surface of the pinion drive assembly is rotatably installed with a support seat;

[0006] An elastic telescopic sleeve is fixedly installed on one side of the outer surface of the support seat, a mounting ring is fixedly connected to the inner surface of the elastic telescopic sleeve, and an anti-slip rubber pad is fixedly connected to one side of the outer surface of the mounting ring;

[0007] A ring gear is fixedly embedded on the outer surface of the focusing hand wheel, and the ring gear matches the pinion driving assembly.

[0008] Furthermore, the pinion gear driving assembly includes a rotating shaft, and one end of the rotating shaft is fixedly connected to the knob, the other end of the rotating shaft is fixedly connected to the pinion gear body, and the pinion gear body is meshingly connected to the ring gear, and the knob can drive the ring gear to rotate through the pinion gear driving assembly.

[0009] Furthermore, the elastic telescopic sleeve includes a spring, and one end of the spring is fixedly connected to the support seat, the other end of the spring is fixedly connected to a limiting ring, one side of the outer surface of the limiting ring is fixedly connected to a movable sleeve, and the mounting ring is fixedly installed on the inner wall of the movable sleeve, the limiting ring limits the moving stroke of the movable sleeve to prevent the movable sleeve from completely moving out of the shell.

[0010] Furthermore, a plurality of limit strips are evenly and fixedly connected to the outer surface of the movable sleeve, and the limit strips are slidably connected to the shell. The setting of the limit strips has a limiting effect and can ensure the stability of the movement of the shell.

[0011] Furthermore, the anti-skid rubber pad abuts against the knob. After the anti-skid rubber pad contacts the knob, the knob is squeezed and limited by friction to prevent the knob from being deflected due to vibration.

[0012] Furthermore, the support base is fixedly connected to the shell, and the shell supports the support base, which is beneficial to the installation of the support base.

[0013] Furthermore, the knob is located on the inner side of the movable sleeve, and the movable sleeve has a shielding effect on the knob to avoid accidental contact.

[0014] Beneficial effects of the utility model:

[0015] The utility model discloses an optical sight with excellent focusing performance. The shell, the knob, the pinion driving assembly, the support seat, the elastic telescopic sleeve, the mounting ring, the anti-skid rubber pad and the ring gear are arranged. The pinion body drives the ring gear to rotate with a deceleration effect, thereby reducing the adjustment range and avoiding the focusing hand wheel from rotating a large angle with a slight force. The focal length can be finely adjusted, making the adjustment more convenient and improving the focusing performance. At the same time, the knob is squeezed and limited by abutment to avoid loosening due to vibration, thereby ensuring the focusing effect. BRIEF DESCRIPTION OF THE DRAWINGS
