1. a door plate opening/closing device for casing, comprising:

  • One panel, described panel comprises a basal wall, and is located at the first projection on described basal wall, and the sidewall in vertical that is connected with described basal wall;

    One door-plate, described door-plate comprises the driving arm that is articulated in described basal wall, described driving arm and described basal wall articulated section are defined as an axis of rotation, described driving arm comprises and second projection separately parallel with described first projection, described door-plate can cover make position on front side of described panel around described axis of rotation one, and one makes to rotate between the enable possition of exposing on front side of described panel;

    AndOne two ends are hooked in the extension spring of described first projection and described second projection respectively;

    When described door-plate is in described make position, described second projection and described axis of rotation position are all positioned at inside described first projection, described axis of rotation position is then positioned on front side of described extension spring, described first, described second projection and described axis of rotation define a triangle jointly, when described door-plate is in a special angle position between described make position and described enable possition, described first projection, described axis of rotation and described second projection are sequentially located along the same line, when described door-plate is rotated to by described special angle position by described make position, described door-plate automatically springs open to described enable possition by the change toward the outer side of point force direction of described extension spring pulling force,Wherein, described driving arm comprises about two arms separately and respectively in accumbency L shape, described second projection is connected between described two arms and contiguous described arm bending place, and described extension spring is placed between described two arms, described door-plate also comprises one in order to cover the plate body on front side of described panel, described driving arm is located at described plate body trailing flank, and described driving arm comprises one in order to abut to limit the stop section of described plate body rotational angle with described sidewall internal face.
