Description

sight base

Technical field:

The invention relates to the technical field of sights, in particular to a sight base.

Background technique:

In order to facilitate the shooter to aim at the target and improve the shooting hit rate, a sight is installed on the gun, wherein the sight is fixed on the receiver cover of the gun through the sight base, and the sight is a detachable part. The development of firearms has greatly improved the accuracy of firearm shooting, enabling shooters to accurately aim at small or long-range targets, and sights have gradually become the basic configuration of shooters. However, along with the widespread popularization of sights, the problems of sights are also gradually exposed. There is a large instantaneous recoil force in the shooting process of the gun, which is the reaction force of the bullet to the gun after the bullet is fired; due to the precision optical lens installed in the sight, the recoil force has a great impact on the sight and the sight. As far as the optical lens is concerned, it is a fatal injury. After the bullet is fired, the main body of the gun is first affected by the recoil force, and the main body of the gun will have a retreat displacement. However, the sight will remain in its original position due to inertia, because The gun and the sight are rigidly connected, so the gun body will pull the sight through the sight base, so that the sight will retreat with the gun body. In the process, the gun body has a The higher the precision of the sight, the heavier the weight of the sight, the greater the inertia of the sight, the greater the instantaneous pulling force of the gun on the sight base, and the easier the sight base will be torn , shattered or broken, especially the locking screw on the base of the sight, the locking screw is more likely to be torn, shattered or broken. In addition, the optical lens in the sight also has inertia relative to the sight, and the optical lens is fixed in the sight. When the sight is pulled back, the sight will also pull the optical lens back together with the sight, so , the sight will also have a large instantaneous pull on the optical lens inside, and the higher the precision of the sight, the greater the weight of the optical lens in the sight, and the greater the inertia of the optical lens, the greater the impact of the sight on the optical lens. The greater the instantaneous pulling force of the lens, the easier it is for the optical lens to be shattered.

Due to the existence of the recoil force, the optical lens in the sight base and the sight is often damaged or out of position, so the user needs to change the sight frequently, which brings great trouble to the gun user.
