Hole, is connected anti-fall hook with firm banking by bearing pin, and then turns into unified structure with door body；The torsionspring is enclosed within bearing pin
On, one end is arranged on firm banking, and the other end is arranged on anti-fall hook；One end buckle of the steel wire rope is fixed on anti-fall
The top of hook, compresses torsionspring, and the other end and the chain of steel wire rope link together.
Furtherly, according to the size of door body, the number of the anti-fall hook of configuration is increased.
Furtherly, the anti-fall hook top sets connecting hole, by connecting rod by multiple anti-fall hook connects together.
Furtherly, one end buckle of the steel wire rope is fixed on the top of anti-fall hook or is fixed in connecting rod
Between.
Furtherly, a retainer ring is set on the door-plate connecting plate, 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 invention are as follows：
Invention enhances the usage safety performance of rapid door, the safe operation of user of service is not only ensure that, also ensured
The safe operation function of equipment, furthermore achieved that the interactive safety of human body, at the same all parts processing of this mechanism it is simple,
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.
