Novel equipment cabinet vibration isolator

Abstract

The invention discloses a novel equipment cabinet vibration isolator. The novel equipment cabinet vibration isolator comprises an equipment cabinet. Vibration absorbing devices are mounted on the lower surface of the equipment cabinet and the surface of the rear side of the equipment cabinet. The sizes and the structures of the set of vibration absorbing devices are same. Each vibration absorbingdevice is composed of a mounting plate, a plurality of through holes, screws, a steel wire rope type vibration isolator body, a vibration isolator compensating guiding plate, a set of sliding groovesand vibration isolator adjusting blocks, wherein the mounting plate is mounted on the lower surface of the equipment cabinet; the multiple through holes are machined in the upper surface of the exterior of the mounting plate at equal intervals; the screws are mounted in the multiple through holes correspondingly; the steel wire rope type vibration isolator body is mounted on the lower surface of the exterior of the mounting plate; the vibration isolator compensating guiding plate is mounted at the other end of the steel wire rope type vibration isolator body; the set of sliding grooves are formed in the positions, close to the two ends, of the lower surface of exterior of the vibration isolator compensating guiding plate and extend in the length direction of the vibration isolator compensating guiding plate; and the vibration isolator adjusting blocks are mounted in the set of sliding grooves correspondingly. The novel equipment cabinet vibration isolator has the beneficial effects ofbeing simple in structure and high in practicability.

Description

technical field [0001] The invention relates to a vehicle-mounted cabinet, in particular to a novel cabinet vibration isolator. Background technique [0002] With the development of modern military technology, the requirements for vibration isolation and buffering of airborne, vehicle-mounted, and ship-borne electronic and mechanical equipment are getting higher and higher. Not only the vibration reduction and reinforcement of a single device is required, but also the overall vibration reduction and reinforcement of the cabinet where the equipment is placed. . The cabinet is restricted by factors such as weight and height, and the bottom and back fixed shock isolators are usually used for buffering and vibration reduction. The bottom shock isolator usually adopts a wire rope shock isolator. This type of shock isolator can withstand elastic deformation in any direction of freedom in space, and multi-directional vibration isolation and buffering. The function of the back sho...

AI Technical Summary

Problems solved by technology

In harsh environments such as vehicle-mounted field transportation and airborne climbing, the cabinet tends to be unstable in the depth direction or tilts or swings at an excessively large angle during relative motion, which will cause the center of gravity of the cabinet to deviate sharply from the theoretical value, resulting in the selection of the cabinet. Vibration isolator failure due to exceeding the rated load

[0003] To solve these problems, a shock isolator with adjustable stiffness and damping can be designed, which can make the damping element of the current shock isolator invalid, solve the problem of equipment without protection devices, and finally ensure the normal use of equipment such as cabinets
