Abstract

The invention discloses a spring-combination-type vibration isolator. One end of an inner hole of a shell is provided with an inner thread, and the other end of the inner hole is provided with the end face with a cross slot hole; an anti-rotation sleeve is arranged in the inner hole; the anti-rotation sleeve is provided with a semi-enclosed annular groove in the axial direction; the enclosed side of the anti-rotation sleeve clings to the end face of the inner hole of the shell; an axial rigidity buffer is arranged in the annular groove; a locking bolt is in a stepped shaft-shaped structure; the small end of the locking bolt is inserted into a center hole of the anti-rotation sleeve; the big end of the locking bolt extends out the shell; the big end of locking bolt is provided with a threaded hole for installation in the axial direction; an axial-horizontal rigidity buffer is arranged on an outer circle of the big end of the locking bolt; and a regulating thread sleeve is arranged in the inner hole of the shell through threaded connection and is positioned in an outer layer of the axial-horizontal rigidity buffer for regulating the tightness thereof. The vibration isolator of the type has the advantages of small volume, light weight, adjustable triaxial rigidity and the like. A cross anti-rotation device on the back end part of the locking bolt can prevent the accompanying rotation of the vibration isolator when a screw is arranged and wound, so that the wrench space for installation is saved.

Description

1. Technical field [0001] The invention relates to a vibration isolator used on small electronic equipment carried on bombs or fighter planes, and belongs to the field of environment and reliability control of electronic equipment. 2. Background technology [0002] Airborne electronic equipment of missiles and fighter jets has the characteristics of small size and light weight, but the vibration and shock environment in which the electronic equipment is located is very harsh, and the volume must be small, and there is not even space to place the installation wrench. Therefore, the vibration isolator should not only be small in size and have excellent vibration isolation and buffer performance, but also require that the connecting bolts themselves have anti-following devices. [0003] figure 1 It is the structure diagram of a foreign product. It is mainly composed of a shell 21, a connecting shaft 22, a rubber spring 23, a nylon anti-rotation sleeve 24, a wave spring 25 and ...
