Detailed Description
The utility model is further described below with reference to the accompanying drawings. The following examples are only for illustrating the technical solutions of the present invention more clearly, and the protection scope of the present invention is not limited thereby.
The embodiment discloses a sling anti-drop safety device, as shown in fig. 1 and fig. 2, comprising a hook body 1, an arc-shaped slide bar 2 and an anti-drop buckle 3,
a hook body 1 including an inner space for accommodating a hanging strip and an opening;
the arc-shaped sliding rod 2 is positioned at one end of the opening and is connected with the lifting hook body 1;
the anti-tripping device 3 comprises a sliding end and a free end, and the sliding end is connected with the arc-shaped sliding rod 2 in a sliding manner; the anti-drop buckle 3 has an anti-drop state for closing the opening and an anti-drop release state for opening the opening, and the free end of the anti-drop buckle 3 is connected with the lifting hook body 1 in the anti-drop state; under the anticreep relieved state, the slip end of anticreep knot 3 slides along arc slide bar 2, and the free end is close to or keeps away from lifting hook body 1 along with the action of slip end, realizes anticreep knot 3's side direction and rotates.
The technical concept of the utility model is that the arc-shaped slide rod is arranged on the hook body 1, so that the anti-tripping device slides along the arc-shaped slide rod, thereby realizing the lateral rotation of the anti-tripping device, maximally releasing the internal space of the hook, facilitating the taking of the hanging strip and avoiding the potential safety hazard of forcibly placing the hanging strip by the compression spring type anti-tripping device.
