Abstract
The invention discloses a rotary lifting hook. The rotary lifting hook comprises a lifting hook body and a liting ring. The lifting hook body is movably connected to the lower portion of the lifting ring, and the lifting hook body and the lifting ring are connected through a hemisphere. A hemisphere hole which is used for supporting the hemisphere and is matched with the hemisphere in shape is formed in the bottom of the lifting ring. A connecting through hole is formed in the hemisphere in the axial direction, and a connecting shaft on the upper portion of the lifting hook body penetrates through the hemisphere hole to be fixed to the connecting through hole in a threaded mode. The rotary lifting hook is simple in structure, the three centers (the center of a weight, the center axis of the lifting hook body and the center axis of a lifting ring hole) can be automatically adjusted by the hemisphere to coincide, the lifting hook body can rotate automatically on the horizontal plane by 360 degrees, friction is small, breakage is unlikely to occur, and the service life is long.
Description
technical field:
The present invention relates to a kind of suspension hook, particularly relate to a kind of shackle hook.
Background technology
Suspension hook directly contacts connection with the many employings of suspension ring both at home and abroad at present, and do not possess the function at automatic adjustment center, when suspension hook hoisting heavy, the center of gravity of weight may depart from the line of centers of suspension hook, causes suspension hook to be not only subject to axial tensile force, also can be subject to the diametral load from suspension ring, suspension hook is caused easily to fracture, and usually there is localized bumps, friction phenomenon, cause suspension hook serious wear, service life is short.
Also having between some suspension ring and suspension hooks adopts the parts of bearing and so on to connect, to ensure that suspension hook can turn at a plane internal rotation, but can not overlap with the line of centers of self and the line of centers three of suspension ring by center-of-gravity regulating, suspension hook, bearing, suspension ring all can bear very large diametral load, frangibility, damage.
Summary of the invention
That the technical problem to be solved in the present invention is existing suspension hook is serious with suspension ring structural wear, can not overlap with the line of centers of self and the line of centers three of suspension ring by center-of-gravity regulating, and suspension hook easily fractures, and service life is short.
For solving the problems of the technologies described above, the technical solution used in the present invention is: shackle hook, comprise suspension hook and suspension ring, suspension hook is movably connected in below suspension ring, described suspension hook is connected by semi-round ball with suspension ring, the bottom of suspension ring is provided with half ball and cylindrical hole vertically, half ball is for propping up semi-round ball and agreeing with the spherical shape of semi-round ball, half ball top internal diameter is greater than bottom inner diameter, and the bottom of half ball is communicated with cylindrical hole, the internal diameter of cylindrical hole equals the bottom inner diameter of half ball, described semi-round ball arranges connecting through hole vertically, the adapter shaft on suspension hook top is fixed with connecting through hole screw thread through after cylindrical hole and half ball.
Suspension hook and semi-round ball link together, semi-round ball coordinates with suspension ring hemisphere interporal lacuna, make semi-round ball can under the towing force of half ball, 360o automatic rotation is done in arbitrary plane, thus make suspension hook when hoisting heavy, under gravity, can with semi-round ball automatic center-of-gravity regulating, center of gravity is overlapped with the line of centers of self and the line of centers of suspension ring half ball, namely semi-round ball possesses self-aligning function, ensure that suspension hook only bears axial tensile force, the gap this ensures that thering suspension hook and suspension ring cylindrical hole is uniform, there will not be localized bumps, friction phenomenon, such suspension hook would not have wearing and tearing, breakage phenomenon, durable in use, in addition, semicircle sphere bearing load, load diatibution is even, reduce wear, also protect suspension ring simultaneously.
Further, the bottom inner diameter of described half ball is that the top internal diameter of 1/3rd, half ball of semi-round ball external diameter is slightly larger than semi-round ball external diameter.First, the diameter due to semi-round ball is slightly less than the upper inner diameter of half ball, semi-round ball and hemisphere interporal lacuna is coordinated, is convenient to semi-round ball and slides in half ball; Secondly, because half ball lower inner diameter is 1/3rd of the diameter of semi-round ball, make half ball can while holding semi-round ball preferably, the space that can also do not hinder suspension hook to rotate completely.
Advantage of the present invention is: structure is simple, three-core unification, namely sling weight time suspension hook center of gravity overlap with the line of centers of suspension hook, suspension ring, suspension hook only bears axial tensile force, can do 360o automatic rotation in the horizontal plane, wear and tear little, not frangibility, long service life.

Detailed description of the invention
As shown in figures 1 to 6, the present invention includes suspension ring 1, suspension hook 4 and semi-round ball 3, bottom suspension ring 1, be provided with half ball 2 and cylindrical hole 5 vertically; Semi-round ball 3 props up in half ball 2, and semi-round ball 3 arranges connecting through hole vertically, after the adapter shaft 4-1 on suspension hook 4 top runs through cylindrical hole 5 and half ball 2 from the bottom to top successively, is threaded with connecting through hole.
Described half ball 2 for sidewall be the through hole of sphere, through hole upper inner diameter is large, and lower inner diameter is little; Half ball 2 lower inner diameter is 1/3rd of the diameter of semi-round ball 3, and the diameter of semi-round ball 3 is slightly less than half ball 2 upper inner diameter.
The internal diameter of described cylindrical hole 5 equals the bottom inner diameter of semicircle orifice 2, and is greater than the diameter of the adapter shaft 4-1 of suspension hook 4.
The benefit of such setting is, first, the diameter due to semi-round ball 3 is slightly less than half ball 2 upper inner diameter, makes semi-round ball 3 and half ball 2 free-running fit, is convenient to semi-round ball 3 and slides in half ball 2; Secondly, because half ball 2 lower inner diameter is 1/3rd of the diameter of semi-round ball 3, make half ball 2 while holding semi-round ball 3 preferably, can also ensure that cylindrical hole 5 leaves enough spaces and arbitrarily rotates for suspension hook 4.
During use, because suspension hook 4 and semi-round ball 3 link together, half ball 2 free-running fit of semi-round ball 3 and suspension ring 1, make semi-round ball 3 can under the towing force of half ball 2, 360o automatic rotation is done in arbitrary plane, thus make suspension hook 4 when hoisting heavy, under gravity, can with semi-round ball 3 automatic center-of-gravity regulating, the line of centers of center of gravity with the line of centers of self and half ball 2 of suspension ring 1 is overlapped, namely semi-round ball 3 possesses self-aligning function, ensure that suspension hook 4 only bears axial tensile force, this ensures that there the gap uniformity between suspension hook 4 and half ball 2 of suspension ring 1, there will not be localized bumps, friction phenomenon, such suspension hook 4 would not have wearing and tearing, breakage phenomenon, durable in use, in addition, during the semicircle sphere bearing load of half ball 2, load diatibution is even, reduce wear, also protect suspension ring 1 simultaneously.
