According to the anti-gravity seat, a fixed
pulley block is installed on a supporting stand column, a movable
pulley block is installed on a seat body, the fixed
pulley block and the movable pulley block are in transmission connection through a pull
rope, a user can achieve height change of the seat body by pulling the pull
rope, and the anti-
gravity effect is achieved. And the falling protector is arranged to prevent the seat main body from rapidly falling to the ground, so that the use safety is improved. By applying the fixed pulley block and the movable pulley block, the labor-saving effect is achieved, the working intensity of an operator is relieved when the device serves as outdoor equipment, compared with an air cylinder structure, no complex hydraulic or pneumatic
system exists, the overall structure is simple, fault points caused by complex components are reduced, the
fault occurrence probability is reduced, and the working efficiency is improved. The pulley block can better adapt to the severe outdoor environment, maintenance is relatively simple, the maintenance difficulty and cost are reduced, a user can directly face the structure of the pulley block, meanwhile, the user can experience in real time, the learning effect is improved, and the use safety is improved by arranging the falling protector.
