Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1 and 3, an embodiment of the present invention provides an anti-unhooking device for a construction hoisting machine, including: articulate gag lever post 2 in 1 upper shed one side of couple, lie in the opposite side structure of its hinged end on gag lever post 2 and have a logical groove along its length direction, insert in logical inslot portion and be equipped with a dead lever 21, couple 1 upper shed's opposite side is seted up one with the spacing hole 12 of dead lever 21 looks adaptation, still include an elastic component, it is used for providing the dead lever 21 towards spacing hole 12 direction compels tight power, it needs to notice, the aforesaid compels tight power and can drive the inside that dead lever 21 inserted spacing hole 12.

In this embodiment, there is a limiting rod 2 hinged to one side of the opening of the hook 1, and a fixing rod 21 is inserted into the through groove of the limiting rod 2, the fixing rod 21 is inserted into the limiting hole 12 of the hook 1 through the elastic force of the elastic member, so that the opening of the hook 1 is closed, and when a heavy object is hung inside the hook 1, the opening can be closed by the fixing rod 21 and the limiting rod 2, so that the heavy object cannot fall off from the hook 1.
