Description
Technical Field
[0001] The utility model belongs to the technical field of sights and relates to a device for improving the continuous magnification accuracy of a steering system of a sight. Background Art
[0002] Sights are mainly divided into the following three categories: telescopic sights, collimating sights, and reflex sights. Among them, telescopic sights and reflex sights are the most popular. The above two types of sights are mainly used during the day, so they are collectively referred to as day light sights. In addition, there are night vision sights for night aiming, which are telescopic sights and reflex sights with night vision devices added. According to the type of night vision device, they can be divided into low-light sights and infrared sights.
[0003] A steering mirror chamber and an inner tube are provided inside the sight. The existing gap between the steering mirror chamber and the inner tube ranges from 0.01 mm to 0.02 mm. Due to the large gap, the steering accuracy cannot be ensured during continuous magnification change, affecting the use effect of the sight. Utility Model Content
[0004] In view of the above problems existing in the prior art, the present application provides a device for improving the continuous zoom accuracy of a sight steering system.
[0005] The technical solution of the utility model is as follows:
[0006] A device for improving the continuous zoom accuracy of a sighting mirror steering system comprises a steering mirror chamber and an inner tube. The outer cylinder of the steering mirror chamber is inserted into the inner hole of the inner tube. An exhaust groove is provided in the steering mirror chamber. Through holes one are equally divided along the circumference of the right side of the exhaust groove. A rubber pad one is placed in the through hole one. Through holes two are equally divided along the circumference of the left side of the exhaust groove. The rubber pad two is placed in the through hole two. The gap between the inner tube and the steering mirror chamber is less than 0.001 mm. The compressed air and negative pressure generated when the steering mirror chamber moves to the two ends of the inner tube are discharged through the exhaust groove.
[0007] As a preferred embodiment of the utility model: the inner tube is provided with a variable magnification straight groove.
[0008] As a preferred embodiment of the utility model: the left side of the inner tube is processed with an external thread 1, and the right side of the inner tube is processed with an external thread 2.
[0009] As a preferred implementation manner of the utility model: the through hole 1 and the through hole 2 have the same size, and the rubber pad 1 and the rubber pad 2 have the same size.
[0010] As a preferred implementation of the utility model: the steering mirror chamber and the inner tube are made of aluminum tubes.
[0011] The beneficial effects of the utility model are:
[0012] The utility model discloses a device for improving the continuous zoom accuracy of a steering system of a sight. Through holes are equally divided along the circumference of the left and right sides of an exhaust groove. Rubber pads are installed in the through holes. The gap between an inner tube and a steering mirror chamber is less than 0.001 mm. Due to the reduction of the gap, the steering accuracy of the sight can be improved when the zoom is continuously changed, and there is no image jump phenomenon, thereby ensuring the accurate use of the sight, which is convenient and reliable.
