Fig. 2 is a schematic structural view of the main body.
Fig. 3 is a schematic view showing a structure of the present invention when it is coupled with a hook.
Wherein: 1. the fastening device comprises a main body 101, connecting pins A and 102, flanges A and 103, screw holes 104, flanges B and 105, connecting pins B and 2, fixing screws 3, bolts B and 4, nuts B and 5, bolts A and 6 and nuts A.
Detailed Description
The utility model will be further described with reference to the accompanying drawings.
The hook anti-falling device comprises a main body 1, a fixing screw 2, a nut and a bolt, wherein the main body 1 comprises a screw hole 103, a connecting pin A101, a connecting pin B105, a wing plate A102 and a wing plate B104, the main body 1 is 7-shaped, the main body 1 is formed by integrally forming the wing plate A102 and the wing plate B104, the top of the main body 1 is provided with the screw hole 103, the fixing screw 2 is installed in the screw hole 103, and the fixing screw 2 is fastened on a hook; the two ends of the main body 1 are provided with a connecting pin A101 and a connecting pin B105, a bolt A5 penetrates through the connecting pin A101, the two ends of the bolt A5 are fixed through nuts A6, a bolt B3 penetrates through the connecting pin B105, and the two ends of the bolt B3 are fixed through nuts B4.
The number of the main body 1 is 2.
The number of the fixing screws 2 is 2.
The inner diameter of the screw hole 103 is larger than the outer diameter of the fixing screw 2.
The length of the wing plate A102 is larger than that of the wing plate B104.
The included angle between the wing plate A102 and the wing plate B104 is 60-70 degrees.
The diameter of the screw hole 103 of the hook anti-falling device is slightly larger than that of the fixing screw 2, so that the device can be freely lifted up and down after being fixed on the hook. The included angle between the wing plate A102 and the wing plate B104 is 60-70 degrees, and the specific (most suitable) angle is determined according to the style, the size and the opening size of the straight-handle single hook. 2 main part 1 leans on bolt and nut to fix, and the hook is in 2 main part 1 middles, and the top of main part 1 passes through set screw 2 fastening on the hook.
The length of the wing plate A102 is larger than that of the wing plate B104, and under the natural state, the wing plate B104 acts as a baffle at the opening of the hook by virtue of the self-weight principle, so that the suspension cable tool is prevented from falling off. When unhooking, the end part of the wing plate A102 is lifted by hand, and the hook sleeve of the rope rigging is taken out.
