The specific embodiment

A kind of as shown in drawings hand-pinch type can be controlled Lifesaving device, stretches out the rope 4 of casing by casing 1, an end, and rope can be materials such as nylon or steel wire rope, and the reel 2 and the centrifugal friction arrestment mechanism 11 that twine rope are formed; Described reel 2 rotating being fixed in the casing, this reel one end stretches out outside the casing, is connected with handle 16; Reel 2 keys are mounted in the rotating shaft 8, and rotating shaft 8 two ends are installed on the casing by bearing, and there is driving gear 15 at the two ends of reel, and there is ratchet 9 in the outside of driving gear, and driving gear, ratchet and reel are installed in the same rotating shaft 8; Respectively there is a button 6 both sides, top of described casing 1, and each button connects a linkage 5, and an end that links to each other with button 6 on the linkage has spring 7 to link to each other with casing, the ratchet 91 that the terminal connection of linkage and ratchet 9 are suitable; Driving gear 15 is meshed with driven gear 14, and driven gear 14 is mounted on the driven shaft 10 by key below driving gear 15, and centrifugal friction arrestment mechanism 11 is installed on the driven shaft; The end that rope 4 stretches out casing 1 top forms lasso trick or coupling hook 3, can overlap on the fixtures such as hanging over wall, and the bottom of casing 1 connects safety belt 13 by suspension hook.

Linkage 5 is made up of master connecting-rod 52 and slave connecting rod 54, and master connecting-rod one end connects button 6, and this end below has spring 7 to be connected between master connecting-rod and the casing 1; The master connecting-rod middle part is hinged with the hinged-support I51 that is fixed on the casing, the vertical auxiliary connection connecting rod 54 of the master connecting-rod other end, and the rear end of slave connecting rod and ratchet 91 is hinged; The position of ratchet is corresponding with ratchet, and the middle part of ratchet is hinged with the hinged-support II 53 that is fixed on the casing.After pressing the button 6, master connecting-rod 52 1 ends move downward, and spring 7 is compressed; Simultaneously, master connecting-rod 52 other ends move upward around jointed shaft, drive slave connecting rod 54 and move upward; The rear end of slave connecting rod 54 pull-up ratchets 91, at this moment, the ratchet front end moves downward around jointed shaft simultaneously, and inserts in the tooth of ratchet 9, stops ratchet 9 to rotate, because ratchet 9 is coaxial with reel 2, thereby reaches braking effect.

Centrifugal friction arrestment mechanism 11 is made up of sleeve 111, roller 112 and friction pulley 113; Described sleeve 111 is fixed on the bottom of casing 1 inner chamber by gusset 12, friction pulley 113 is arranged in the sleeve, the friction pulley center is fixed on the driven shaft 10, and there are a plurality of unidirectional teeth the outer ring of friction pulley 113, and cylindrical roller 112 is arranged in the wedge shape space between unidirectional tooth and the sleeve lining.When the escape apparatus decrease speed was too fast, because driving gear 15 is coaxial with reel 2, it was by meshing with driven gear 14 and driving friction pulley 113, and wherein, the rotating speed of driven gear is not slower than the rotating speed of driving gear; As shown in Figure 3, friction pulley 113 is rotated counterclockwise, and sleeve 111 is fixing, and then under the effect of sleeve and roller frictional force, roller will be by wedging narrower and small side in wedge shape space, thereby makes the friction pulley stall, reach the purpose of braking.

When accidents such as fire occurring, the utility model is hung on the fixture on the building, the escape personnel puts on safety belt 13, hand pinches button 6, release button then the utility model together descends with the people, when needs when a certain height or excessive velocities need be stopped, handle ratchets ratchet braked thereby can pinch button 6 control link mechanisms 5, coaxial because of ratchet and reel, reach the purpose that stops at an arbitrary position.Can continue behind the release button to descend, if decrease speed is too fast or when forgetting the operation locking key because of anxiety, this moment, the centrifugal friction device played a role, and reached the purpose of friction catch, thereby effectively the escape personnel had been carried out protection once more.When needs are wrapped in rope on the reel, can realize by rotating receipts rope handle 16.
