Claims (1)

[Scope of utility model registration request] A drawer type that is held in a closing switchboard so that the drawer can be freely pushed in and moved in the front-rear direction so that a movable side contact part fixed to the back side of the switchboard closes and opens with respect to a fixed side contact part provided on the switchboard. In a shutter device for a closing switchboard that operates to close or open the fixed side contact portion in conjunction with the back and forth movement of the electrical equipment, a shutter seat guide piece that guides a shutter seat that supports the shutter of the shutter device is provided. a main rail that is fixed and held so as to be able to move up and down in a vertical direction to the frame of the switchboard; a sub rail to which a front and rear lever for horizontal movement is fixed and which can similarly move up and down; a main lever movably connected to a pin disposed below the main rail via an elongated hole; a sub-lever movably connected to a pin disposed below the sub-rail via an elongated hole and constituting a link mechanism that operates the main rail and the sub-rail together with the main lever; and the draw-out electric device. The main rail and the sub rail are moved up and down via the main lever and the sub lever while rotating between two parallel strikers that are provided on the side of the device and move horizontally as the device moves back and forth. two rollers disposed adjacent to each other at one end of the link mechanism so as to move the link mechanism, and when the drawer-type electrical equipment moves back and forth within the switchboard, one of the two rollers is moved. A first roller rotates between the two strikers and along their inner sides, causing the main lever to move the main rail up and down, and then the second roller similarly rotates between the two strikers. The secondary rail is moved up and down by the secondary lever while rotating along the inner side thereof, and the shutter guided piece fixed to the main rail moves up and down, and the horizontal groove of the guide piece and the secondary rail are moved up and down. A closed switchboard characterized in that a pin fixed to the shutter seat that engages with both diagonal grooves of the fixed front and rear levers moves back and forth along the horizontal groove of the shutter seat guide piece. shutter device.
