Embodiment 1

[0018] refer to figure 1 Make one and be used for the explosion-proof box in the passenger cabin of civil aviation, this casing 7 outermost layer is by the decorative shell 2 of 0.5 millimeter thick aluminum plate, and the height of this shell 2 is 750 millimeters, and width is 305 millimeters, and thickness is 800 millimeters. Can also make the casing 7 of explosion-proof box with the dining car in the passenger cabin of civil aviation and transform into explosion-proof box, the internal structure of its dining car is the same with the explosion-proof box structure.

[0019] The door 1 is symmetrically arranged on both sides of the box body 7. The door 1 is made of a special closed-cell polyurethane material. Symmetrical venting. According to the actual situation of the civil aviation cabin, the explosion-proof box of the civil aviation cabin can be placed in a suitable position of the aircraft, and the two opposite side doors 1 are respectively facing the direction where th...

Embodiment 2

[0023] Make an explosion-proof box used in the passenger cabin of civil aviation. The outermost layer of the box is a decorative shell made of 0.5 mm thick aluminum plate. The symmetrical doors on both sides of the box are made of special closed-cell polyurethane material. The inside of the shell is closely attached to a porous material layer, which is in the shape of a square tube with open ends, and is made of a special closed-cell polyurethane material. The inside of the porous material layer is closely attached to a layer of impact-resistant tube. In this embodiment, The shell is made of a composite material with a certain rigidity, and the others are the same as in Embodiment 1.

[0024] The above-mentioned special closed-cell polyurethane material is prepared from isocyanate, combined polyether and metal powder; among them, the isocyanate is dimethylmethane diisocyanate isomer, and the combined polyether has a density of 200kg / m 3 , the closed cell rate is 95%, and the p...

Embodiment 3

[0026] The porous material layer in Example 2 is placed in the shell made of composite material, and then the shell is set in the impact-resistant tube, which can further save the volume of the explosion-proof box in the civil aviation cabin, and the others are the same as in Example 2. .

Abstract

A explosion-proof tank consists of tank body and a layer of explosion buffer material on inner wall of the tank body. The doors are set symmetrically on two side walls of tank body in opposite direction, the most outer layer of tank body is a layer of decoration shell. An impact resistance barrel with opening at two sides is shrunk on in explosion-proof buffer material layer and a shell liner in barrel form with opening at two sides is shunk on in impact resistance barrel. The openings of the three are communicated to each other as they are set in aim at the doors, the three are sealed together to be in one with a vacuumizing tube being seal-set between shell and shell liner.

Description

technical field [0001] The invention relates to an explosion-proof device related to the safety of civil aviation transportation, in particular to an explosion-proof box used in the passenger cabin of civil aviation. Background technique [0002] The usual explosion-proof containers are spherical, cylindrical or a combination of spherical and cylindrical containers made of metal. Generally, the explosion-proof strength is improved by increasing the distance between the explosive and the container wall and increasing the strength and thickness of the container wall. The distance between the large explosive and the container wall means increasing the volume of the container, increasing the strength and thickness of the container wall means increasing the weight of the container. In air transportation, volume and weight are very valuable. Therefore, the volume and weight of explosion-proof boxes that simply adopt such conventional explosion-proof measures cannot meet the needs ...
