Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the embodiment of the utility model is carried out
Clearly and completely describing, it is clear that described embodiment is only the utility model part of the embodiment, rather than whole
Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are not under the premise of creative work is made
The every other embodiment obtained, belong to the scope of the utility model protection.
Fig. 1-2 is referred to, the utility model provides a kind of technical scheme：A kind of crane hook self-locking device, including even
Termination 1 is connect, connection end 1 has suspension hook 2, and the one end of suspension hook 2 is provided with semi-circular chute, and chute wall is provided with sliding mouth, chute
It is interior to be provided with ball 10, card rope plate 8 is fixedly connected with the ball 10, card rope plate 8 runs through sliding mouth and stretched out, card rope plate 8
One end of extension is provided with groove, and groove upper side edge is openning shape, and groove two side is rotatably connected to rotating shaft 7, consolidated in rotating shaft 7
Surely rotating bar 5 is socketed with, rotating bar 5 and card rope plate 8 are rotatablely connected, and the radian rotated is 15 °~75 °, extrudes and blocks in gravity
Rotating bar 5 coordinates ball 10 to slide and rotate during rope plate 8, and the one end of rotating bar 5 away from rotating shaft 7 is welded with interior snap ring 6, interior snap ring
