Description

Technical Field

[0001] The invention relates to a vibration reduction mechanism, in particular to a spring vibration reduction mechanism with a quick locking function. Background Art

[0002] Due to its precision, optomechanical equipment has high requirements for optical axis stability and consistency, especially for aiming optomechanical equipment, which needs to ensure its optical axis. Since sighting optoelectronic equipment is directly mounted on top of firearms and artillery, the multi-dimensional vibration and shock during shooting have a strong impact on the optoelectronic equipment. In addition to seriously affecting the optical axis, it will also greatly reduce the life of core components such as movement and detector. At present, there are usually two types of connection between optoelectronic equipment and weapons: one is direct rigid connection, and all core components rely on hard resistance, with low reliability and life; the other is to use a spring damping seat. Because the spring can delay the shock time, the impact energy can still be effectively reduced, but the direction of its vibration reduction is divergent, random and uncontrollable, and cannot guarantee the precision of the optoelectronic equipment. In addition, bolts are often used when connecting the base to the weapon system, which is troublesome to disassemble and assemble, and time-consuming and labor-intensive. Summary of the invention

[0003] The technical problem to be solved by the present invention is to provide a spring vibration reduction mechanism with a quick locking function, which can effectively reduce vibration, effectively ensure the stability of the optical axis and the reliability of the whole machine, and can also be quickly locked on the weapon system.

[0004] The technical solution of the present invention to solve the above technical problems is as follows: a spring vibration reduction mechanism with a quick locking function, comprising a base, a mounting seat and two guide rods, two base guide rod supports are fixedly connected on both sides of the base, two mounting seat guide rod supports are fixedly connected on both sides of the mounting seat, the mounting seat is located at the top of the base, one of the mounting seat guide rod supports on each side is located between the two base guide rod supports on the same side, each of the base guide rod supports is provided with a base guide rod support hole, each of the mounting seat guide rod supports is provided with a mounting seat guide rod support hole, and the same side The central axes of each of the base guide rod support holes and each of the mounting seat guide rod support holes are in a colinear relationship, and each of the guide rods passes through the base guide rod support holes and the mounting seat guide rod support holes on the same side in sequence; a vibration reduction device is provided between each of the base guide rod supports and each of the mounting seat guide rod supports to reduce the vibration of the base guide rod supports when they are impacted, and also includes a locking device to limit the relative position of the guide rod and the base, and the mounting seat can move along the length direction of the guide rod; a quick clamping device is provided at the bottom of the base to quickly clamp the base and the weapon system.

[0005] The beneficial effects of the present invention are as follows: the guided vibration reduction mechanism not only avoids rigid connection, but also adds a guide rod for guidance, so that the photoelectric device can only move with a small displacement along the direction of the guide rod. At the same time, the spring can delay the impact time and reduce the impact energy. The combination of the guide rod and the spring can solve the guidance and vibration reduction problems at the same time.

[0006] Reduce the strong vibration and strong impact of the weapon system on the optomechanical equipment during firing, and at the same time make the optomechanical equipment only move with a small displacement in the direction of the optical axis through the guide rod, and use the precision of the guide rod to effectively ensure the stability of the optical axis and the reliability of the whole machine. This guided vibration reduction mechanism can be widely used in vibration reduction and precision guidance of optomechanical equipment in strong impact and strong vibration environments, effectively ensuring the stability of the optical axis of the equipment and the reliability of the equipment in harsh environments such as strong vibration and impact.

[0042] Working principle:

[0043] 1. Vibration reduction principle

[0044] The base 1 is locked on the weapon system (such as a gun, cannon, etc.), and the optomechanical equipment (such as a sight, a night vision sight, etc.) is installed on the mounting seat 2. When the weapon is fired, strong vibration is generated. Since the direction of the vibration is concentrated on the axial direction of the guide rod 5, and the mounting seat guide rod support 4 is sleeved on the guide rod 5, the mounting seat 2 moves slightly along the axial direction of the guide rod 5 under the vibration impact, and the springs 6 on both sides of the mounting seat guide rod support 4 can effectively buffer and reduce vibration, while ensuring the vibration reduction and precise guiding of the optomechanical equipment in a strong impact and strong vibration environment, effectively ensuring the stability of the optical axis of the equipment and the reliability of the equipment in harsh environments such as strong vibration impact.

[0045] 2. Locking principle

[0046] The slot formed between the lower base slot 22 and the lower locking seat slot 24 is placed on the guide rail of the weapon system, and the handle 14 is rotated clockwise. The handle 14 drives the rotating arm 13 to rotate clockwise around its central axis. Since the fixed shaft 15 is threadedly connected to the rotating arm 13 through the rotating arm threaded hole 18, the rotating arm 13 approaches the base 1 along the central axis direction of the fixed shaft 15, thereby driving the pressure plate 12 and the locking seat 8 to approach the base 1 along the central axis direction of the fixed shaft 15, so that the lower locking seat slot 24 and the lower base slot 22 are close to each other. When the upper locking seat protrusion 25 is inserted into the upper base slot 23, the limit position is reached. At this time, the slot formed between the lower base slot 22 and the lower locking seat slot 24 matches the shape of the guide rail and clamps the guide rail.
