Description
Technical field
The utility model relates to the dropping-proof hook that a kind of New-type instant is got thing.
Background technology
Existing dropping-proof hook is mainly the suspension hook of torsion shrouding formula and Spring Card compact form type, and its shortcoming is: only have anti-drop device, and anti-drop device be arranged on suspension hook get thing one end, to getting thing, have a certain impact.
Summary of the invention
The utility model is to improve in the technical foundation of existing dropping-proof hook, and the front end of suspension hook is got to thing range extension, conveniently gets thing, and does not affect suspension hook pulling strengrth in actual applications.Be specially:
A dropping-proof hook, this dropping-proof hook comprises the suspension hook body of arc, is provided with rope connecting portion, suspension hook on suspension hook body
The arc inner side of body is provided with suspension hook transfer device, and suspension hook body lower end is provided with the attached body of suspension hook, on the attached body of suspension hook, is provided with suspension hook bill.
Described suspension hook transfer device is tight docile and obedient in the curved portions of suspension hook body.
Described suspension hook transfer device inner side is also provided with flexible button.
Described suspension hook bill and the attached body of suspension hook are can closed type.
The attached body of described suspension hook inner side, suspension hook bill inner side, be connected through control slewing arrangement with suspension hook transfer device end.
The centre of described suspension hook body and the attached body of suspension hook junction is also provided with rotary knob.
Under suspension hook natural conditions and while not getting thing, it is the state shown in Fig. 1 of the present utility model, when suspension hook reaches thing, the rope of thing to be got tangles suspension hook transfer device, thereby driven rotary hinge, by the attached body driven rotary of suspension hook, then forwards the state as Fig. 2 to, due to the deadweight of suspended object, when suspension hook is mentioned, because the effect of gravity can press flexible button, thereby drive suspension hook bill to rotate by controlling slewing arrangement, thereby reach self-locking state.Wherein, rotary gemel and control slewing arrangement all adopt two sections of fixing, centre rotates mechanisms, to guarantee the intensity of mechanism.Suspension hook transfer device can reset according to actual need of production.
Hang the stress analysis of suspension hook Zeng Shouli in thing process and find, the stressed maximum position of suspension hook is the middle epimere of suspension hook body, so the design of the attached body of suspension hook and bill does not affect the intensity of suspension hook.
The utility model structure to suspension hook on original anti-drop function designs cleverly, thereby make the desirable thing range extension of suspension hook, is original more than 3 times, has improved the efficiency of getting thing lifting.
