The both sides of plate face 230,240,220 of piece 23, the right frame piece 24 and the lower frame piece 22 be respectively provided with multiple intermediate plates 231,241,
221, fixed so that the side of the shell fragment 4 corresponding to it is embedded in, the shell fragment 4 and the left frame piece 23, the right frame piece 24 and
Space between the plate face 230,240,220 of the lower frame piece 22, filled with least one first Expandable strip 51.
The roller shutter blade door 3, is made up of multiple blades 31, and the both sides of each blade 31 are respectively provided with a ring hook part
311st, 312, adjacent blade 31 mutually with its ring hook part 311,312 hook linking synthesis one can storehouse folding door body, the roller shutter
The upper end of blade door 3 is pivotally connected with the upper ledge piece 21, and its lower end connects the base 30 of a L-shaped.
The support agency 7, it is fixedly arranged on the side of inside casing 2, to make after the roller shutter blade door 3 is put down to it
Hold, the support agency 7 includes an automatic returning hinge 71 and a top holding piece 72 (is provided with one in the automatic returning hinge 71
Torsion spring, this is prior art, therefore not shown in figure), the first lateral plate 711 of the automatic returning hinge 71 and the top holding piece 72
It is affixed, and an active side is formed, the second lateral plate 712 and the left frame piece 23 (the right frame piece of the automatic returning hinge 71
24) it is affixed, and an affixed side is formed, the top holding piece 72 is held in institute when the roller shutter blade door 3 is stacked into folding state
A first side 313 of blade 31 is stated, and when the roller shutter blade door 3 is put down, holds and clamps the roller shutter blade door 3
One side.
The left frame piece 23, its front side fixed one before catch 6, the preceding catch 6 is to the spacing roller shutter blade door 3
