Description

Technical Field

[0001] The invention relates to the technical field of sight connection, in particular to a shock-absorbing and buffering connection mechanism for an infrared sight. Background Art

[0002] The white light sight that comes with the current 12.7mm dual-purpose machine gun can no longer meet the new battlefield requirements. If infrared sights are used, there are many advantages: 1. It can expand the observation range. Infrared sights can convert infrared rays that are imperceptible to the human eye into visible images, greatly expanding the effective observation range of soldiers at night, so that soldiers can promptly detect distant targets and potential threats; 2. It can improve combat effectiveness and shooting accuracy. After clearly observing the target through the infrared sight, soldiers can aim and shoot more accurately, which improves the hit rate of weapons at night; 3. It is convenient for night operations. Troops equipped with infrared sights become more efficient and safer in marching, reconnaissance, infiltration and other operations at night, and can approach the target or pass through complex terrain more quickly, reducing obstacles and mistakes caused by insufficient light; 4. It can change the use of tactics and increase the frequency of night battles. The emergence of infrared sights has made night combat no longer a special and restricted form of combat, but a normalized combat option; 5. It can innovate tactical means, such as using the advantages of infrared sights to conduct night raids, ambushes, special operations, etc., and can find breakthroughs in the relatively weak links of the enemy's night defense and create opportunities.

(5) The sight needs to reduce vibration during operation, but stability cannot be sacrificed at the same time. Therefore, the energy-absorbing adapter plate and the adapter seat are embedded and connected with each other to ensure the certainty of the structural positioning. (6) The energy-absorbing adapter plate is made of wood or composite materials with good vibration energy absorption performance. It not only protects the infrared sight, but also protects the locking connection between the Picatinny rail and the locking seat and locking bolt, and can effectively prevent the locking from loosening due to vibration; (7) A rubber shock-absorbing sleeve and a shock-absorbing spring are provided between the first and second mounting ears. This is because the shock-absorbing spring has high strength and energy absorption capacity, and has good vibration buffering ability, and can convert violent vibrations into relatively soft vibrations of its own. The rubber shock-absorbing sleeve has good energy dissipation capacity. When the shock-absorbing spring converts vibrations into its own vibrations, the shock-absorbing sleeve is required to eliminate the vibration energy. The combination of the two can not only reduce the strong vibrations suffered by the sight, but also reduce the slight shaking of the sight. BRIEF DESCRIPTION OF THE DRAWINGS
