Abstract

The present invention comprises a bottom board which is provided with a center sleeve. A ratchet core axle supported by a bearing is in the center sleeve, the front end of the ratchet core axle is provided with a three-rod bottom plate by keys, the three-rod bottom plate is provided with three three-rod rotating support heads which mutually form an angle of 120 degrees, the three-rod rotating support heads are connected with metal rods, and the three-rod bottom plate is also provided with an emergency opening device. When the power is cut, the rods on a horizontal position can automatically fall off to open the present invention. The back end of the ratchet core axle is provided with a center plate which is fixedly connected with a ratchet and an inward-concave wheel plate by the keys, a vertical sleeve and screws and can freely rotate in the center sleeve. The components use shifting forks of ratchet pawls on the left side and the right side of the ratchet for limiting the forward rotation or the reverse rotation of the ratchet, and the forward rotation or the reverse rotation of three rods on the front end is simultaneously limited. The action of the shifting forks of ratchet pawls is controlled by electromagnets on both sides of the bottom board for preventing one of the three rods from moving in a horizontal state or rotating to obtain the purpose of closing or opening the door.
