Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.

As shown in fig. 1, a safety device of a lifting hook comprises an anti-drop buckle base 1 fixed on the neck of the lifting hook through a pin shaft, an anti-drop buckle plate 2 hung on the anti-drop buckle base 1, and a baffle plate 3;

the anti-falling buckle seat 1 is provided with a limiting bulge 6, and one end of the limiting bulge 6 close to the anti-falling buckle seat 1 is thinner than one end far away from the anti-falling buckle seat;

as shown in fig. 3, the anti-dropping buckle plate 2 is provided with a mounting hole 5 and a limiting hole 4, the limiting hole 4 is positioned above the mounting hole 5 and communicated with the mounting hole 5, one end of the anti-dropping buckle plate 2 is clamped in the limiting protrusion 6 through the limiting hole 4, the other end of the anti-dropping buckle plate extends towards the tail of the lifting hook, and the limiting protrusion 6 can only pass through the mounting hole 5 to be separated from the anti-dropping buckle plate; the thickness of the anti-drop hasp plate is 4mm;

the baffle is used for limiting the anti-falling buckle plate 2 to move, so that the limiting protrusion 6 cannot enter the mounting hole 5 from the limiting hole 4. As shown in fig. 4 and 5, the baffle 3 is located at the top of the anti-drop buckle seat 1 and is rotatably connected with the anti-drop buckle seat 1. The anti-falling hasp plate 2 is far away from one end of the tail part of the lifting hook and is propped against the baffle 3. The end face, close to the tail part of the lifting hook, of the anti-falling buckle plate 2 is inwards sunken to form a groove matched with the tail part of the lifting hook. The diameter of the mounting hole 5 is 22mm.

The limiting bulge is composed of a round rod and a disc, the diameter of the round rod is smaller than that of the disc, and the diameter of the disc is 15mm. The length of the round bar is equal to the thickness of the anti-drop hasp plate 2.

The mounting hole 5 is a round hole with the diameter larger than that of the disc, the limiting hole 4 is in a long strip shape, and the width of the limiting hole is smaller than that of the disc and larger than that of the round rod.

The utility model discloses a use method:
