Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
Referring to fig. 1-4, the present invention provides a technical solution: a draw arm upper-mounted lifting hook structure with a buffering function comprises a shell 1, wherein a rotating wheel 2 is mounted inside the shell 1, a movable shaft 3 is arranged inside the rotating wheel 2, the rotating wheel 2 is rotatably connected with the shell 1 through the movable shaft 3, a mounting seat 4 is fixedly connected to the lower end of the shell 1, a supporting plate 5 is fixedly connected inside the mounting seat 4, a first connecting plate 6 is arranged at the upper end of the supporting plate 5, a second connecting plate 7 is arranged at the lower end of the supporting plate 5, a spring 8 is arranged between the supporting plate 5 and the first connecting plate 6, the same spring 8 is arranged between the supporting plate 5 and the second connecting plate 7, a movable rod 9 is fixedly connected to the lower end of the first connecting plate 6, a lifting hook 10 is fixedly connected to the lower end of the movable rod 9, a mounting plate 11 is fixedly connected to the outer side of the lifting hook 10, and;
the diameter of the rotating wheel 2 is smaller than that of the shell 1, so that the rotating wheel 2 can better rotate and is convenient to lift, the through holes 51 are formed in the supporting plate 5, the diameter of each through hole 51 is larger than that of the movable rod 9, the movable rods 9 can conveniently slide up and down, interference is avoided, four groups of springs 8 are arranged at equal intervals, a plurality of springs 8 are arranged at equal intervals in each group, a buffering effect is achieved from two aspects, the buffering effect on the lifting hook 10 is improved, and the service life of the lifting hook 10 is prolonged;
