Abstract

The utility model discloses a vibration damper box applicable on containers for loading and transporting precise instruments, electric products, anti vibration objects and the like. The vibration damper box body takes an aluminium frame(3) as rib reinforcement and a foamed aluminium layer(2) as the base body which serves as a vibration damping layer, and a wearing layer is arranged on an aluminium outer wall(1) of the damper box body. The aluminium frame(3) and the foamed aluminium layer(2) are connected in an inlaying manner through foaming technique, in which the aluminium frame(3) is suspended on a die. The aluminium outer wall(1) of the damper box body is welded at the outside of the foamed aluminium layer(2). Each door for the vibration damper box takes an aluminium frame(9) as rib reinforcement, a foamed aluminium layer(8) as the base body which serves as a vibration damping layer, and an aluminium groove-shaped outer wall(7)as the wearing layer; and the two doors are connected with the damper box body through buckles(4). The vibration damper box realizes reducing vibration and resisting shock without using a vibration damper and greatly reduces resonance. Meanwhile, the vibration damper box can reach the effect of shielding electromagnetism and can reduce the volume of the body of the containers.

Description

The vibration damping case

Technical field

The utility model relates to a kind of vibration damping case, is applicable to loading, the carrying case of equipment such as precision instrument, electronic product, vibrationproof article.

Background technology

Along with development of modern industry; all trades and professions are more and more higher to the reliability requirement of equipment such as precision instrument, electronic product, vibrationproof article; the interference of mechanical environments such as the vibration damping case that therefore, loads, transports these equipment is vibrated for protecting internal unit to avoid, impact plays an important role.At present, this class vibration damping case product major part all is to adopt the bearing wall and frame structure that suspends, and equipment is installed on the inner frame, and inner frame is connected with housing by 8 rubber dampers, exterior vibratory impulse slows down impact energy by rubber damper, thereby guarantees the safe handling of internal unit.For this class vibration damping case, it mainly has following some problem:

1. too rely on the destruction that shock absorber is alleviated vibration, impacted; therefore the riding position to internal unit has had requirement for restriction; if unmatched words between casing, shock absorber and the internal unit; they might reach resonance; at this moment; shock absorber not only can not protected internal unit, can produce it on the contrary and destroy.

2. most casing adopts plastics or glass fiber reinforced plastics composite material, and cargo-carring as if inside is electronic machine, might be subjected to the interference of external high-frequency electromagnetic in use, also might go to influence the use of other electronic machine as interference source.

3. casing is made up of inner frame, shock absorber, external packets vanning, and in use instrument container is housed also, so overall volume is bigger, and space availability ratio is not high.

Summary of the invention

In order to overcome existing vibration damping case above shortcomings, the utility model provides a kind of vibration damping case, purpose is still to hit by vibration shock isolation under the situation of not using shock absorber, and can reduce the generation of resonance effect to a great extent, also can reach simultaneously the effect of electromagnetic screening, the casing volume is reduced.

For achieving the above object, the technical scheme that the utility model adopted is: a kind of vibration damping case comprises the chamber door at casing and two ends.

Casing is a reinforced rib with the aluminum framework, and the foaming aluminium lamination is matrix (a vibration damping layer), and the aluminum outer wall is constituted by wearing layer.

The aluminum framework is made of in each end points welding 12 dihedral aluminum frame supports, and the aluminum framework is by the aluminum framework being suspended on the mould, forming a kind of inside and outside inserted connection through foam process with being connected of foaming aluminium lamination.

The aluminum outer wall becomes a square casing by aluminium alloy plate through clod wash, is welded in foaming aluminium lamination outside.

Chamber door is reinforced rib with the aluminium sash, and the foaming aluminium lamination is matrix (a vibration damping layer), and aluminum grooved outer wall is constituted by wearing layer.

Aluminium sash is made of in each end points welding four dihedral aluminum frame supports, and aluminium sash forms a kind of inside and outside inserted connection, outside weldings one grooved aluminium alloy plate outer wall through foaming equally with the foaming aluminium lamination on mould.

By the welding of case mouth position 16 of casing and two ends chamber door buckle to take and are connected.

Two corrosion-resistant steel drop handles are respectively welded in the casing both sides.

The beneficial effects of the utility model are:

1. replace original vibration damping case, both reached the purpose that vibration shock isolation hits, can not produce resonance effect again owing to having adopted aluminum framework (frame) to be embedded in the foamed aluminium layer composite structure.

2. because the utility model adopts metal outer wall, so have good electromagnetic shielding action.

3. the utility model unites two into one instrument container and vibration damping case, has reduced the volume of casing to a great extent, also has good heat sinking function simultaneously.
