Detailed Description

The present invention is further described with reference to the accompanying drawings:

as shown in the attached drawings, the hook safety catch is characterized by comprising a front U-shaped rod 1, a rear U-shaped rod 2, a connecting bolt 3, a connecting nut 4 and a connecting ring 5, wherein the two sides of the open end of the front U-shaped rod 1 and the open end of the rear U-shaped rod 2 are respectively connected through the connecting ring 5, the front U-shaped rod 1 and the rear U-shaped rod 2 are connected to the connecting ring 5 at an angle of 45-50 degrees, the connecting bolt 3 is arranged in the connecting ring 5, and the connecting bolt 3 penetrates through the connecting ring 5 on the two sides of the open end of the U-shaped rod and then is fixedly connected through the connecting nut 4.

Further, the rod length of the front U-shaped rod is less than that of the rear U-shaped rod 2.

Further, the safety catch install on

lifting hook

6, 6 rear ends of lifting hook and the opening inboard that the loop wheel machine is connected the position be equipped with connecting hole 7, preceding U type pole 1 and back U type pole 2 cover on lifting hook 6, preceding U type pole 1 extends lifting hook 6 opening inboard, back U type pole 2 covers in the rear outside of lifting hook 6, connecting bolt 3 passes in go-between 5 and the connecting hole 7 fixed through connecting bolt 3, and then installs the safety catch on lifting hook 6.

Furthermore, the open end of the front U-shaped rod 1 is in a necking shape, the open end of the rear U-shaped rod 2 is the same as the caliber of the open end of the front U-shaped rod 1, and the open end of the rear U-shaped rod 2 expands outwards towards the rear side and can be wrapped on a lifting hook 6 of a crane.

Furthermore, the counter weight of back U type pole be greater than the counter weight of preceding U type pole, realize the self return of preceding U line pole through the counter weight.

When the utility model is used, the safety buckle is arranged on a lifting hook 6, a front U-shaped rod 1 and a rear U-shaped rod 2 in the safety buckle are respectively sleeved on the front side and the rear side of the lifting hook 6, a connecting ring 5 is arranged on both sides of a connecting hole 7 of the lifting hook 6, a connecting bolt 3 passes through the connecting ring 5 and the connecting hole 7 to be connected with a connecting nut 4, the front U-shaped rod 1 extends into the opening of the lifting hook 6, the rear U-shaped rod 2 is sleeved on the rear side of the outer side of the lifting hook 6, when an article is lifted, the rear upper part of the rear U-shaped rod 2 is pulled, the front U-shaped rod 1 is further rotated towards the rear side, the opening of the lifting hook 6 is opened, after the lifting is finished, the rear U-shaped rod 2 is pushed back to drive the front U-shaped rod 1 to seal the opening of the lifting hook 6, because the counter weight of the front U-shaped rod is smaller than that of the rear U-shaped rod, therefore, the front U-shaped rod returns automatically, the safety buckle is prevented from rotating when the safety buckle works, the safety buckle is used, simple manufacture, simple to operate, the source of raw materials is more extensive, is applicable to lifting hook such as mobile crane, portal crane, the utility model discloses owing to adopt above-mentioned structure, have advantages such as simple manufacture, simple to operate, security performance height.
