Description
Technical field
The present invention relates to suspender more particularly to a kind of hanging hook assembly of double hook structure.
Background technique
There are two types of the structure types of suspension hook: one kind be it is enclosed, hung suitable for being hooked on rope or bar, have will not
Object the advantages of deviating from from suspension hook is generated, Chinese Patent Application No. is 2012103227376, publication No. is
CN103663123A, entitled " suspension hook " patent document in disclose a kind of enclosed suspension hook；Another kind is open
, that is, it is adapted to be hooked on all objects and be hung, therefore have the advantages that versatility is good.It is in Chinese Patent Application No.
2013104512146, one kind is disclosed in the patent document of publication No. CN103466435A, entitled " lifting hook of steel plate " to open
Put the suspension hook of formula.Open suspension hook includes hanging ring, coupler body and interconnecting piece, and interconnecting piece links together hanging ring and coupler body.It is existing
Although the open suspension hook having have the advantages that versatility it is good, but lose object possessed by enclosed hook be not easy from
The advantages of sliding on suspension hook is then easy to produce object when suspension hook inclination is larger and slides phenomenon and (and ought be hooked in the both ends of object
When the object big to length is hung, suspension hook can be in the biggish state in inclination angle).In addition existing open suspension hook leads to sometimes
It crosses connecting rope and links together in pairs and constitute hanging hook assembly, when use carries out article by the both ends that two suspension hooks are hooked in article
Lifting, the hanging hook assembly of the structure have the disadvantage that the stress of the connecting rope when Item Weight is kept constant can be with article
Growth and increase, be easy to produce phenomenon of rupture when the long article of length so as to cause hanging.
Summary of the invention
The first object of the present invention is intended to provide a kind of double hook structure that can be adjusted rope length and change the stress of connecting rope
Hanging hook assembly, solve existing hanging hook assembly rope length it is non-adjustable caused by be easy to produce fracture when hanging the long article of length
The problem of phenomenon.
When second object of the present invention is intended to further provide for a kind of clasp joint article on the basis of first goal of the invention
The hanging hook assembly for being also easy to produce the double hook structure for sliding phenomenon is not allowed, object is easy to slide when solving the use of existing open suspension hook
The problem of falling.
The above technical problem is solved through the following technical scheme: a kind of hanging hook assembly of double hook structure, including suspension hook,
Appending disk, both ends are passed down through the connecting rope and elevating lever of appending disk, and the both ends of the connecting rope are all connected with the suspension hook, institute
The threaded one end for stating elevating lever is connected with the driven gear for being rotationally connected with the appending disk, the other end is equipped with plug, the liter
Drop bar only liftably links together with the appending disk, and the plug is supported on the middle part of the connecting rope, described driven
Gear engages driving gear, and the driving gear is equipped with drive shaft, and the drive shaft is equipped with holding rod.By two suspension hooks when use
The both ends of article are hooked in, then above appending disk is mentioned and realizes and carried article.When object length changes, held by hold
Bar rotate driving axis, drive shaft drive driving gear rotation, and driving gear drives driven gear rotation, driven gear driving lifting
Bar lifting, lifter rod lifting and make connecting rope go up and down and change length of the connecting rope between appending disk and suspension hook so that
Angle between the part same level direction of connecting rope change to remain unchanged, so that being fallen that Item Weight is constant only to be grown
The stress that degree connects when changing is constant, overcomes rope phenomenon of rupture.
The invention also includes motor and powershift mechanism, the motor includes motor casing and motor shaft, the motor casing
It is fixed together with the holding rod, the drive shaft is connected to one end of the motor shaft, and the powershift mechanism includes
