Through the above technical solutions, using elastic component as the buffering between articulamentum and mid-board, generated when explosion
Impact force is larger and when articulamentum can not stop completely, impact force is changed into the elastic potential energy of elastic component using elastic component, into
One step enhances the protective effect to mid-board.
Further, the articulamentum includes steel plate, the arc-shaped setting of steel plate.
Through the above technical solutions, enhance the protective effect to mid-board using steel plate, also, steel plate is arc, it can
Explosive force is decomposed, avoids mid-board somewhere from concentrating stress, enhances the impact resistance of mid-board.
Further, the connection layer surface is provided with flexible pad.
Through the above technical solutions, enhancing the intensity of connection layer surface using flexible pad, avoid slungshot etc. to articulamentum table
The destruction in face ensures the protective effect of articulamentum.
Compared with prior art, the utility model has the beneficial effects that：
(1) by the way that articulamentum is arranged on mid-board side wall, and rotating member is set on articulamentum, it will be quick-fried using rotating member
The broken kinetic energy that rotating member is converted into the impact energy of mid-board reduces destruction of the explosion to mid-board, ensures holding for mid-board
Principal characteristic energy；
(2) by the way that elastic component is arranged between articulamentum and mid-board, the impact force of explosion is converted on the bullet of elastic component
Property potential energy, enhance protective effect to mid-board.
