Shape body structure offers axis hole before and after the left fulcrum bearing, from left-hand on the boxboard up and down of left fulcrum bearing on boxboard
The right side offered slot, and left sliding rail is located at crossing in slot up and down for left fulcrum bearing.Right fulcrum bearing is the rectangular box structure of right openings,
Axis hole is offered on boxboard before and after the right fulcrum bearing, is offered from right to left on the boxboard up and down of right fulcrum bearing
Slot, right sliding rail are located at crossing in slot up and down for right fulcrum bearing.Through-hole is offered in the upper end of big connecting rod, is connected in the lower end of big connecting rod
There is friction plate.Through-hole is offered in the upper end of small rod, the lower end of small rod is set as semi-axis structure, and pulse plate is hardened for rectangle
Structure, opens up the transverse center hole for being parallel to plate face on pulse plate, and friction plate is connected to the left end of pulse plate, eccentric wheel connection
In the right end of pulse plate, pulse plate is arranged on the lower section of small rod and passes through centre bore and half axis connection on small rod.Dalian
Bar is arranged in fulcrum bearing and between the rearing-box plate and sliding rail of fulcrum bearing, and the friction plate on big connecting rod is corresponding with sliding rail,
Small rod and pulse plate are arranged in fulcrum bearing and between the preceding boxboards and sliding rail of fulcrum bearing, friction plate on pulse plate and
Eccentric wheel is corresponding with sliding rail.The front and rear axle journal of shaft respectively with the axis hole axis connection on boxboard before and after fulcrum bearing, shaft
Axle body is keyed simultaneously with the through-hole on big connecting rod and small rod, the preceding boxboard and driven tooth of the preceding spindle nose Extension support seat of shaft
Wheel connection.Left driven gear in left fulcrum bearing is engaged with left driving gear, the right driven gear in right fulcrum bearing and right active
Gear engages, and left driving gear, by being driven axis connection, is respectively provided with right driving gear between transmission shaft and left and right fulcrum bearing
There is retaining spring, several driving wheels are connected on transmission shaft, and each driving wheel is each in car with being located at by drawstring
Handle connects.
When lift car accidental falling, the passenger in car can pull downward on handle immediately, and handle will pass through drawstring, drive
Driving wheel and transmission shaft drive left and right driving gear rotation simultaneously, and left and right driving gear is driven left by left and right driven gear respectively again
Shaft rotation in right fulcrum bearing, when shaft drives big connecting rod and small rod to be flipped up simultaneously and makes on big connecting rod and pulse plate
Friction plate when being contacted with sliding rail, left and right fulcrum bearing can be fallen by generating frictional force between friction plate and sliding rail to slow down car
The speed fallen, at the same along sliding rail roll eccentric wheel can semiaxis of the driving pulse plate on small rod continuously swing, and because
This driving friction plate carries out sliding rail the point braking of pulsed.
The invention has the advantages that when accidental falling accident occurs for elevator, by the passenger in car by stopping manually
The mode of vehicle carries out emergent self-rescue.

Specific embodiment
In Fig. 1, Fig. 2, Fig. 3, Fig. 4, Fig. 5, Fig. 6, Fig. 8, Tu10Zhong, sliding rail 1 is T-shaped track structure, and two one slide rail 1 is left
The right side is symmetrical arranged.Car 7 is rectangular box structure, and car 7 is arranged between left and right sliding rail 1.Left and right fulcrum bearing 9 is connected to
The left and right ends of 7 top plate of car, left fulcrum bearing 9 are the rectangular box structure of left side opening, before and after the left fulcrum bearing 9 on boxboard
Axis hole is offered, offered slot 10 from left to right on the boxboard up and down of left fulcrum bearing 9, left sliding rail 1 is located at left bearing
Seat 9 is crossed in slot 10 up and down.Right fulcrum bearing 9 is the rectangular box structure of right openings, before and after the right fulcrum bearing 9 on boxboard
Axis hole is offered, offered slot 10 from right to left on the boxboard up and down of right fulcrum bearing 9, right sliding rail 1 is located at right fulcrum bearing 9
Up and down cross slot 10 in.Through-hole is offered in the upper end of big connecting rod 12, friction plate 11 is connected in the lower end of big connecting rod 12.Small
The upper end of connecting rod 16 offers through-hole, and the lower end of small rod 16 is set as 17 structure of semiaxis, and pulse plate 13 is Rectangular Plate Structure,
The transverse center hole for being parallel to plate face is opened up on pulse plate 13, friction plate 11 is connected to the left end of pulse plate 13, eccentric wheel 14
The right end of pulse plate 13 is connected to, pulse plate 13 is arranged on the lower section of small rod 16 and passes through centre bore and half on small rod 16
Axis 17 connects.Big connecting rod 12 is arranged in fulcrum bearing 9 and between the rearing-box plate of fulcrum bearing 9 and sliding rail 1, on big connecting rod 12
Friction plate 11 is corresponding with sliding rail 1, and small rod 16 and pulse plate 13 are arranged in fulcrum bearing 9 and positioned at the preceding boxboard of fulcrum bearing 9
Between sliding rail 1, the friction plate 11 and eccentric wheel 14 on pulse plate 13 are corresponding with sliding rail 1.The front and rear axle journal of shaft 15 point
Not with the axis hole axis connection on boxboard before and after fulcrum bearing 9, the axle body of shaft 15 simultaneously with it is logical on big connecting rod 12 and small rod 16
Hole is keyed, and the preceding boxboard of the preceding spindle nose Extension support seat 9 of shaft 15 is connect with driven gear 2.A left side in left fulcrum bearing 9 is driven
Gear 2 is engaged with left driving gear 3, and the right driven gear 2 in right fulcrum bearing 9 is engaged with right driving gear 3, left driving gear 3
