Embodiment Construction

[0019] exist figure 1 In the shown embodiment, the explosion-proof box used in the passenger cabin of civil aviation includes a box body, and the outer wall of the box body is made of rubber-coated aramid fiber cord. In this embodiment, the aramid fiber cord The diameter of the aramid cord is 0.7mm-1.2mm; the distance between the cords is 70 cords / 10cm-90 cords / 10cm; the thickness of the rubber covering layer is 1-3mm.

[0020] The box body is a rectangular column with an open upper end and a closed lower end. The four corners of the column form chamfered arcs, and the junction between the side walls 3 of the box and the bottom surface 4 of the box body also forms arc-shaped chamfers. The overall dimensions of the rectangular column: 850mm×280mm×850mm. The upper end of the box body is provided with a port traveler 1, and the cord end of the aramid cord that constitutes the outer wall of the box bypasses the port traveler 1 and reverses to wrap the port traveler 1, and the end...

Abstract

The invention relates to an explosion-proof box for civil-aviation passenger cabins. The explosion-proof box comprises a box body, wherein the outer wall of the box body is glue-coated cord fabric with aramid cords; two or more than two layers of glue-coated cord fabric are provided; the cords of different cord fabric layers are arranged crossways; the box body is in the shape of a rectangular column of which the upper end is opened and the lower end is sealed; four corners of the column are at circular-arc chamfer angles; a joint of the outer sidewall and the bottom surface of the box body is at an arc chamfer angle; and the outer wall of the box body is provided with exhaust holes. As the explosion-proof box is manufactured by use of the glue-coated cord fabric with the aramid cords, the disadvantage that the explosion-proof boxes used in the conventional explosion-proof measures are too heavy and too big is overcome.

Description

(1) Technical field: [0001] The invention relates to a safety explosion-proof measure related to the safety of civil aviation transportation, in particular to an explosion-proof box used in a civil aviation cabin. (two) background technology: [0002] At present, the usual explosion-proof containers are made of metal, including circular and cylindrical containers. Generally, the explosion-proof strength is improved by increasing the distance between the explosive and the container wall and increasing the thickness of the container wall. Increase the distance between the explosive and the container wall. The distance means increasing the volume of the container and increasing the thickness of the container wall, which means increasing the weight of the container. In air transportation, the volume and weight of the air carrier are very valuable. Existing common explosion-proof boxes are made of metal, and all have the problems of excessive weight and volume, and are not suita...
