Vibration isolation buffer for resisting strong impact

Abstract

The invention discloses a vibration isolation buffer for resisting strong impact. In the vibration isolator, a base sleeve is used as a main frame, and the base sleeve is internally provided with a main spring module, a damp buffer spring module and a connecting structure module. A circle of buffer mesh pad is filled between the inner circle of the base sleeve and a straight reed and a bent reed of the damp buffer spring module to form an elastic garter spring. When the buffer is subjected to greater horizontal impact force, the buffer mesh pad can enhance the buffering effect and restrain the straight reed and the bent reed, thereby the straight reed and the bent reed can not separate from a hold-down mechanism to scatter. In addition, a vertical buffer spring is additionally arranged, therefore, when a main spring makes displacement under vertical impact force and contacts the buffer spring, the buffer spring can counteract part of the impact force, and when the impact force disappears, the buffer spring can provide help for the resetting of the main spring.

Description

technical field [0001] The invention relates to a vibration isolation buffer device for electromechanical equipment, in particular to a safety vibration isolation buffer which is suitable for adopting a standard general cabinet in the electronic equipment cabin of a ship and withstands strong impact. Background technique [0002] The ship's electronic equipment (system) is not only precisely manufactured, but also under harsh working conditions. In addition to being subjected to mechanical environments such as vibration, shock, and swing during normal navigation, it may also be subjected to underwater explosions such as mines and torpedoes, our weapons, etc. during wartime. Strong shock excitation caused by launch and enemy weapon hit, so a very good vibration isolation and buffer protection is required. [0003] As the standardization, generalization and modularization of naval electronic equipment are getting higher and higher, for electronic equipment with different funct...
