Unidirectional fence gate

Abstract

The invention relates to a unidirectional fence door, comprising door, closing tube, door shaft, bottom plate, stop block, foot board, compressing spring, hanging column, hook, torsion spring and live shaft. When humans go away through the fence, at first they can tread the foot board and make the position of foot board moves downward. So stop block and hook so on, which formerly make door close tightly, are set in opening status. Then they go out by pushing door. Opened door is returned in the closed status under the force of torsion spring after outer force is removed. Here the compressing force to foot board by the stop block is removed. Under the force of compressing spring, the foot board is returned to the highest position and the hook moves upward to enter into the hanging hole at the edge of door. In this way, only when humans in fence tread the foot board, the door can be opened. But outer humans can not pull the door to enter in. so it is provided with the unidirectional passing performance and can prevent human entering from the export randomly.
