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 to 2, the present invention provides a technical solution: the utility model provides a construction is with triangle-shaped chain block convenient to adjust, includes lifting hook 1, chain block 2 and lower lifting hook 4, it installs at chain block 2's top to go up lifting hook 1, it has fixed axle 11 to go up the welding on the lifting hook 1, chain 8 has been cup jointed on the fixed axle 11, link 9 has been detained to the end of chain 8, rotation axis 12 is passed through to chain block 2's both sides and bin 3 is fixed, lifting hook 4 under 2 lower parts of chain block are connected through hoisting chain 10, processing has sawtooth 7 on the lifting hook 4 down.

As a preferred embodiment of the present invention, the lower hook 4 is provided with a split pin 6.

As a preferred embodiment of the present invention, the storage box 3 has an opening, and the storage box 3 is circular.

As an optimal implementation mode of the utility model, the round hole has all been seted up to the both sides of bin 3 and chain block 2's both sides, makes the screw pass the round hole, is convenient for fix bin 3's position.

As a preferred embodiment of the present invention, the diameter of the storage box 3 is larger than the width of the chain block 2, so that the storage box 3 can rotate without touching the edge of the chain block 2.
