Detailed Description

The present invention will be further described with reference to the accompanying drawings.

The vibration test fixture for the toxin filtering box shown in the attached drawings 1 to 2 comprises a base 1 and a plurality of clamping plates 2, wherein the clamping plates 2 are parallel in the same direction, span over the base 1 and are in relative sliding fit with the base 1; the clamp plate 2 is provided with a plurality of vertical bayonet grooves 9, and the interfaces connected with the gas mask are arranged on the gas filter boxes, so that the adaptability of the clamp and the gas filter boxes can be improved by correspondingly placing the interfaces of the gas filter boxes at the bayonet grooves 9; the bayonet grooves 9 are distributed on the same side of the clamping plate 2; the clamping plate 2 and the base 1 adjacent to each other form a clamping cavity 10; the test toxin filtering box 12 is arranged in the clamping cavity 10, the interface of the test toxin filtering box 12 corresponds to the bayonet groove 9, and the adjacent clamping plate 2 slides and is clamped, so that the clamping of the toxin filtering box is completed.

The upper surface of base 1 is even equidistance wavy, because the outline of straining poison box is the arc more, the setting on wavy surface can increase base 1 with experimental strain poison box 12's contact point promotes the centre gripping effect.

The bayonet grooves 9 are arranged corresponding to the wavy wave bottoms on the upper surface of the base 1 one by one; the appearance of the poison filtering box on the market is mostly in an axisymmetric structure, when the interface of the poison filtering box corresponds to the bayonet groove 9, the outer contour of the poison filtering box can just form two contact points with the wavy surface, and the whole structure is more reasonable.
