By using technique scheme, embed in mounting groove during hanging deck Guan Bi, coordinating keeper to be positioned on door leaf by hanging deck, before and after both securing hanging deck, securing hanging deck up and down, make hanging deck fixing more firm in door leaf.
Of the present utility model it is further arranged to: described door leaf is provided with fixing seat, and described installing hole is arranged on described fixing seat.
By using technique scheme, after explosion wave prevention active door uses, keeper front end is pressed in installing hole, hanging deck can be opened, easy to operate.
Of the present utility model it is further arranged to: described air-vent is positioned at below the projection of described hanging deck.
By using technique scheme, hanging deck just can cover air-vent during Guan Bi under the impact of the shock wave of blast, it is ensured that the normal use of explosion wave prevention active door.
Of the present utility model it is further arranged to: described door leaf end face is provided with fixed arm, and described hanging deck is provided with the articulated jib being articulated with described fixed arm one end.
By using technique scheme, during hanging deck Guan Bi, articulated jib is connected on fixed arm, makes articulated jib be connected to hanging deck, and bounce-back when closing hanging deck positions, and the locating effect making hanging deck is more preferable.
Of the present utility model it is further arranged to: described door leaf is provided with multiple installing hole and keeper.
By using technique scheme, make multiple points and location, direction after hanging deck Guan Bi, improve the locating effect of hanging deck further.
Of the present utility model it is further arranged to: described air-vent is square, and described hanging deck is the square hanging deck coordinated with described air-vent.
By using technique scheme, square air-vent and hanging deck, reduce producting process difficulty, simple in construction, cost is relatively low.
Of the present utility model it is further arranged to: described door leaf is provided with multiple described hanging deck.
By using technique scheme, explosion wave prevention active door ventilation effect in normal state is more preferable.
In sum, this utility model has the advantages that keeper front end is wedge shape spigot surface, the other end connects spring, after hanging deck contact lozenges, keeper producing the active force of an installing hole, spring deforms upon, hanging deck ejects installing hole under the action of the spring by keeper after installing hole, keeper side is connected to the front end face of hanging deck, thus reaches to position hanging deck, and after preventing hanging deck from hitting door leaf with bigger impulse force power, bounce-back forms gap；Hanging deck is attached by articulated jib and fixed arm, both the range of accommodation of hanging deck had been expanded, there is the one end being connected to fixed arm by articulated jib, make articulated jib that the end face of hanging deck is produced an active force, reach the effect of second positioning, so that the effect of hanging deck location is more preferable, reduce gap when hanging deck closes and between door leaf, prevent other harmful substance in blast from entering indoor harm personal safety by gap.
