Claims

[Scope of utility model registration request]

The movable frame is housed in or pulled out from the fixed frame through mutual movement guide means provided on both the movable frame to which the electrical equipment is fixed and the fixed frame in which the movable frame is housed. On the movable side provided in the electrical equipment, the contact and the fixed side contact provided on the fixed frame close or open each other, and at this time, the movable side contact and the fixed side contact In the locking device for a drawer-type electrical appliance, the movable frame is locked to the fixed frame in a closed position and a predetermined mutually opened position, wherein A cam gear, which is provided at the other end of the cam support shaft which is supported at both ends and has a cam at one end, is provided symmetrically with the cam and has a tooth profile on its peripheral edge, and is provided at an appropriate position on the fixed frame and meshes with the tooth profile of the cam gear. The movable frame side movement guide is rotated clockwise or counterclockwise around the cam support shaft by a gear having teeth using a suitable operating handle, and is linked to the rotation of the cam and the cam gear. A movement shaft fixed to the means moves inside a movement guide groove formed in the fixed frame side movement guide means,
The movable frame is moved relative to the fixed frame from a mutually closed position of the predetermined contacts to an open position of the predetermined contacts, or vice versa, by means of the cam. movably connected via a link to one end of a means for locking the movable frame-side movement guide means and the fixed frame-side movement guide means when the contacts are in mutually closed or separated positions; The chain is manually operated in advance to release the lock between the movable frame side movement guide means and the fixed frame side movement guide means of the locking means when storing or pulling out from the fixed frame. A driving means of the locking means is operated together with the rotation of a cam gear and a cam that move the movable frame, and drives the locking means to bring the predetermined contacts of the movable frame into a mutually closed position or a disengaged position. A locking device for a drawer-type electric appliance, characterized in that locking between the movable frame-side movement guide means and the fixed frame-side movement guide means is automatically performed again in the above.
