Detailed Description

An embodiment of the descent control device of the present invention is further described with reference to fig. 1 to 3.

The utility model provides a descent control device, includes reel 2 and establishes urceolus 1 outside reel 2, it has steel cable 4 to wind on reel 2, be equipped with the through-hole 3 that supplies steel cable 4 to pass on

urceolus

1, 2 central point of reel puts and rotates and is connected with center pin 5, the eccentric position of reel 2 is equipped with a plurality of connecting rods 6, the both ends of connecting rod 6 all are connected with planet carrier 7, the eccentric position of planet carrier 7 is equipped with a plurality of planetary gear 15, be equipped with two on the center pin 5 respectively with two planetary gear 15 meshing's on the planet carrier 7 sun gear 14, be equipped with two ring gear 13 on urceolus 1 respectively with two planet carrier 7 on, the one end of center pin 5 is connected through the keyway cooperation with urceolus 1, be equipped with clockwork turntable 11 on the center pin 5, it is connected with wind spring 12 to rotate on the urceolus 1, the one end of wind spring 12 is fixed on clockwork turntable 11, the outside that corresponds two planet carriers 7 on the center pin 5 is connected with fixed plate 8 through one-way bearing 18, it is connected with friction disc 10 to rotate on the fixed plate 8, the one end of friction disc 10 is connected with spring 9, the one end of spring 9 is fixed on fixed plate 8, planetary gear 15 deviates from the opposite side of planet carrier 7 and is equipped with the connection pad 16 of being connected with planet carrier 7, be equipped with pivot 17 on the connection pad 16, pivot 17 is connected with fixed plate 8 through one-way bearing 18.
