Below in conjunction with details and the performance of accompanying drawing detailed description according to the concrete device that the utility model proposes.
The utility model housing (3), left cover (16), right lid (6) form outer contoured shape and inner two cavitys.In the right cavity center shaft (5) is housed, line wheel (4) and steel wire cable (2), center shaft (5) frame is on right cover plate (6) centre hole and housing (3) centre hole, line wheel (4) is contained on the center shaft (5), steel wire cable (2) one ends are affixed and twine on online wheel the (4), one end is connected with hook (1), increase line wheel (4) size, winding steel wire cable (2) thereon can extend, thereby falling head is strengthened and the speed adjustable range increase, with the rightabout housing of fix screw (7) (3) wall on have window, this is the door of pulling out steel wire cable (2).Fix screw (7) and hook (1), in-line during use, they are body and people's the devices of being connected and fixed.When the people escapes, the suffered gravity of human body passes through steel wire cable (2), act on online wheel the (4) and go up the formation moment, and import left cavity by center shaft (5), center shaft (5) is equipped with sun gear (9) and key (8) at an end of left cavity, the stair-stepping transition gear of being made up of miniature gears and big gear wheel (10) that is one is housed on the transition wheel shaft (11), wherein, miniature gears and sun gear (9) engagement, big gear wheel and escape wheel (15) engagement, human body or weight obtain decay and reach the escapement governor through the two-stage gear transmission because of the moment that gravity produces.The escapement governor is a core institution of the present utility model, and its function is to realize that human body slowly descends and automatic speed regulation, and it mainly is made up of escape wheel (18) and balance wheel (19).Escape wheel (18) is contained on the pallet arbour (14), and rotates together with the escape wheel (15) that is contained on the pallet arbour (14), and balance wheel (19) is sleeved on the
