Furtherly, the number of anti-fall hook is configured according to the size of door body, increase.
Furtherly, connecting hole is set at the top of the anti-fall hook, by connecting rod by multiple anti-fall hook connects together.
Furtherly, one end of the steel wire rope is fixed on the top of anti-fall hook with buckle or is fixed in connecting rod
Between.
Furtherly, a retainer ring is set on the door-plate connecting plate, and steel wire penetrating retainer ring is connected with chain, makes steel
Cord will not disorderly fly, interference door body operation.
Furtherly, a slotted eye is opened on the anti-fall hook, one end of torsionspring is arranged in slotted eye；The firm banking
End face sets a hole, and the other end of torsionspring is arranged in hole.
Furtherly, the anti-fall hook is in class " sickleshaped ", and head is narrower, backward more and more wider, and top is provided with sawtooth knot
Structure.
Furtherly, the chain anti-off device is arranged on the door-plate connecting plate of door body bottom door-plate, the left and right sides
It is symmetrical arranged.
Usually, anti-fall hook is lifted by the steel wire rope on chain, torsionspring compression；Once generation chain breaks
When splitting, steel wire rope will come loose, in the presence of torsionspring, the rotation of anti-fall hook, so snap into door-plate connecting plate and guide rail it
Between, broached-tooth design at the top of anti-fall hook rapidly increasing friction force and can rotate, and the whereabouts of door body be controlled, by by torsion
Turn effective cooperation of spring and steel wire rope, prevent rapid door during use because of chain breakage and caused by potential safety hazard, further
Protection people, car, thing, the purpose of door safety are reached.
Compared with prior art, the beneficial effects of the utility model are：
The utility model enhances the usage safety performance of rapid door, not only ensure that the safe operation of user of service,
The safe operation function of equipment has been ensured, furthermore achieved that the interactive safety of human body, while all parts processing of this mechanism
Simply, assembling is easy, and operability is high, and Stability Analysis of Structures, it is applied widely, can also be applied to existing mounted rapid door
Transformation.
