attached to each other, therefore, the inner area of the protection plate main body 18 is replaced to be sealed, the micropores 13 in the protection plate main body 18 are arranged in the upper area, after the movable sealing plate 3 falls down, when the protection plate main body 18 rotates to a certain angle, the inclined plane 19 at the bottom of the movable sealing plate 3 is attached to the inclined plane of the protection plate main body 18, so that the movable sealing plate 3 enters a sealing state, the protection plate main body 18 is limited by the gravity of the movable sealing plate 3, meanwhile, the bottom of the movable sealing plate 3 is provided with a sealing gasket which can further improve the attaching degree of the movable sealing plate 3 and the protection plate main body 18, the attaching part of the movable sealing plate 3 and the protection plate main body 18 passes over the micropores 13, and gas is prevented from overflowing from the micropores 13, so that the splashing of smoke dust after the explosion of the battery pack 12 is greatly avoided, the bottom of the movable sealing plate 3 and the top of the protection plate main body 18 are provided with horizontal sections which are attached to each other, and the length of the horizontal sections is lower, when the detection is carried out, if the group battery 12 does not produce the detonation, when backplate main part 18 does not have horizontal direction rotary drive power promptly, movable closing plate 3 will unable drive backplate main part 18 and continue to deflect, improve the convenience when the device is experimental greatly, after group battery 12 produces the detonation, backplate main part 18 deflects under the air current promotion, make backplate main part 18 horizontal segment position remove, thereby make backplate main part 18 edge and the laminating of 3 bottom inclined planes 19 of movable closing plate, backplate main part 18 will continue to deflect under movable closing plate 3 gravity and the air current drive this moment, until inclined plane 19 and the laminating of backplate main part 18 inclination, backplate main part 18 and movable closing plate 3 closely laminate and make between the movable closing plate 3 be close to each other and realize the airtight to region around group battery 12 this moment under the elastic frenulum 21 spring action.
