Description

The hanging hook assembly of double hook structure

Technical field

This utility model relates to suspender, particularly relates to the hanging hook assembly of a kind of double hook structure.

Background technology

The version of suspension hook has two kinds: a kind of for enclosed, it is adaptable to being hooked on rope or bar and hang, having will not Produce the advantage deviate from from suspension hook of object, Chinese Patent Application No. be 2012103227376, publication No. be CN103663123A, entitled " suspension hook " patent document in i.e. disclose a kind of enclosed suspension hook；Another kind is open , i.e. it is adapted to be hooked on all of object and hangs, therefore there is the advantage that versatility is good.In Chinese Patent Application No. it is 2013104512146, publication No. is CN103466435A, i.e. discloses one in the patent document of entitled " lifting hook of steel plate " and open Put the suspension hook of formula.Open suspension hook includes suspension ring, coupler body and connecting portion, and suspension ring and coupler body are linked together by connecting portion.Existing But although the open suspension hook having have the good advantage of versatility lose the object that enclosed hook had be not easy from The advantage of landing on suspension hook, i.e. the most easily produce object landing phenomenon when suspension hook tilts bigger (and when be hooked in the two ends of object When hanging the object that length is big, suspension hook can be in the state that inclination angle is bigger).The most existing open suspension hook leads to sometimes Cross connection rope to link together in pairs composition hanging hook assembly, be hooked in the two ends of article by two suspension hooks during use and article are carried out Lifting, the hanging hook assembly of this structure has the disadvantage that the stress connecting rope when Item Weight keeps constant can be along with article Growth and increase, thus easily produce phenomenon of rupture when causing the article hanging length length.

Utility model content

First purpose of the present utility model aims to provide a kind of can adjustment and restricts long and change the double hook of the stress connecting rope The hanging hook assembly of structure, solve existing hanging hook assembly rope length non-adjustable and cause the article hanging length length time easily produce The problem of phenomenon of rupture.

Second purpose of the present utility model further provides for a kind of hook on the basis of being intended to first utility model purpose It is not easy to produce the hanging hook assembly of the double hook structure of landing phenomenon when connecing article, solves thing when existing open suspension hook uses The problem of the easy landing of body.

More than technical problem is that and solved by following technical proposal: the hanging hook assembly of a kind of double hook structure, including suspension hook, Appending disk, two ends are passed down through connection rope and the elevating lever of appending disk, and the two ends of described connection rope all connect described suspension hook, institute Stating suspension hook is stainless steel structure, the threaded one end of described elevating lever connect have be rotationally connected with described appending disk driven gear, The other end is provided with jaw, and described elevating lever the most liftably links together with described appending disk, and described jaw is supported on described Connecting the middle part of rope, described driven gear engagement driving gear, described driving gear is provided with drive shaft, and described drive shaft is provided with holds Hold bar.During use, two suspension hooks are hooked in the two ends of article, then on carry appending disk and realize having carried article.Work as object length During change, rotating drive shaft by hold holding rod, drive shaft drives driving gear to rotate, and driving gear drives driven gear Rotate, driven gear drive lifter rod lifting, lifter rod lifting and make connect rope lifting and change connection rope be positioned at appending disk And the length between suspension hook so that connect rope this part same level direction between angle change to keep constant so that The stress connected when must be changed by falling the constant only length of Item Weight is constant, overcomes rope phenomenon of rupture.
