Abstract

A suspension device. A U-shaped rope-penetrating part (2) is arranged on a suspension body (1), a U-shaped mouth of the U-shaped rope-penetrating part (2) and the suspension body (1) form a rope-penetrating hole (1.1), the suspension body (1) is further provided with a rope winding wheel (6) provided with a groove used for winding of ropes, a suspension hole (1.2) bearing weight of a human body is formed in the position inclining to one side, and a manipulating handle (1.4) controlling the deflection of the suspension device is arranged on the other side of the suspension hole (1.2). When the suspension device is used, a working rope penetrates through the rope-penetrating hole (1.1) and bypasses the rope winding wheel (6) and is wound on the rope groove, a fixed end of the working rope is fixed on the high, a free end of the working rope droops to the lower, and the human body is fixed and connected with the suspension hole (1.2). When the human body is independently born and suspended by the suspension hole (1.2), the fixed end and the free end of the working rope are pressed tightly with each other and prevent the working rope from sliding, the human body is suspended and stopped on the high, and the suspension device is in a self-locking state. When the human body exerts tension on the suspension device through the manipulating handle (1.4), the suspension device deflects to reduce the pressure between the fixed end and the free end of the working rope or separate the fixed end and the free end of the working rope, and the rope begins to slide and the human body descends.
