Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the utility model and are not intended to limit the utility model.
As shown in FIGS. 1 and 2, the automatic locking device convenient for unhooking by using a push rod comprises a connecting section 2, wherein the connecting section 2 is arranged at the neck of a lifting hook, in the embodiment, the connecting section 2 is U-shaped, and the opening side of the connecting section 2 is arranged towards the rear part of the neck of the lifting hook. The two sides of the connecting section 2 are respectively and fixedly connected with a locking counterweight 1, and the locking counterweight 1 is positioned on the two sides of the rear part of the lifting hook 6. The anterior fixedly connected with lock plate 4 of linkage segment 2, inside the arc region of lifting hook 6 was arranged in to lock plate 4, when the locking state, the bottom of lock plate 4 and the hook point inboard of lifting hook 6 offset and then restrict the tool to lock at the arc region of lifting hook 6 inside.
