It is threadedly coupled across hemisphere with hemisphere and extension end passes through elastic washer and nut check.It is threadedly coupled easy for assemble or unload.
Further, the diameter of half ball is 2/3rds or more of cylinder bore diameter.Suspension hook is hung on hanging ring, is hung
The weight of hook and lifting object is born by hanging ring, and the bearing capacity of hanging ring bottom is maximum, and institute is frayed at most.Limit half ball and cylinder
The diameter ratio in hole is the size in order to guarantee the support position of suspension hook bottom, and the size at support position is bigger, suspension hook entirety stress
Better, bottom abrasion is smaller.
The utility model has the beneficial effects that hemisphere rotates centering in half ball, double of ball of hemisphere has grinding effect,
After long-time use, the compatible degree of half ball and hemisphere is higher and higher, and two contact surfaces are more and more smooth, under gravity,
Vacuum state will be generated between two mating surfaces, generate movement interference.Venthole or slot are communicated through half ball with atmosphere, air
Enter mating surface through venthole, breaks the vacuum state of mating surface, and under the rotation status of hemisphere, it will also be in hemisphere and hemisphere
One layer of air film is formed between hole, reduces the friction between hemisphere and half ball, extends the service life of suspension hook hanging ring, securely and reliably
Property is higher.

Specific embodiment
It is preferred below in conjunction with attached drawing and one kind to keep the purpose of this utility model, technical solution and advantage clearer
Embodiment the technical solution of the utility model is clearly and completely described.
In the following description, on the basis of the orientation of shackle hook shown in Fig. 1, the top of shackle hook as shown in the figure is
For "upper", on the contrary is "lower".
Embodiment 1
Refering to fig. 1 to Fig. 3, spherical rotary suspension hook includes hanging ring 01, hemisphere 02, suspension hook 03 and nut 04.
The central part of the bottom of hanging ring 01 is axially arranged with half ball 011, and half ball 011 is blind hole and opening up.Hemisphere
The central part of the bottom in hole 011 is axially arranged with cylindrical hole 012, and cylindrical hole 012 is through-hole, and cylindrical hole 012 is connected to half ball 011.
The aperture of cylindrical hole 012 is the one third of the diameter of half ball 011.
Hemisphere 02 is adapted to half ball 011, and the spherical diameter of hemisphere 02 is slightly less than and half ball 011, the center of hemisphere 02
Portion is axially arranged with internal thread through hole 021, and outer rim axially penetrates through half ball and offers venthole 022, and venthole 022 is cylinder
Hole is equipped with 6 altogether, is uniformly distributed in the present embodiment.The quantity of venthole is not easy excessively, to guarantee that the intensity of hemisphere is limited.
The upper end of suspension hook 03 is cylindrical, and body diameter is less than the internal diameter of hanging ring cylindrical hole 012.The upper end of cylinder is equipped with outer
Screw thread, external screw thread are adapted to the internal screw thread of hemisphere.The upper end of suspension hook 03 connects movably through cylindrical hole 012 and 02 screw thread of hemisphere
It connects, and is locked by elastic washer and nut 04.02 support of hemisphere can arbitrarily be rotated in half ball, be hung in half ball 011
Hook can be freely rotated in cylindrical hole.
Embodiment 2
Embodiment 2 and embodiment 1 are essentially identical, the difference is that only, the spherical surface of hemisphere 02 is equipped with air channel
022 ', air channel 022 ' is opened up along ball surface, runs through sphere up and down.In the present embodiment, the cross sectional shape of air channel 022 ' is
Semicircle is equipped with 6 altogether, is uniformly distributed.Air channel is opened up from top to bottom, after air flows into hemisphere from top to bottom along hemisphere side wall
It is flowed out from the cylindrical hole 012 of suspension hook bottom, ventilatory effect is more preferable, is easier to break the vacuum state of hemisphere and half ball mating surface.
Embodiment 3
Embodiment 3 and embodiment 2 are essentially identical, the difference is that only, the cross sectional shape of air channel 022 " is three
It is angular, it is equipped with 6 altogether, is uniformly distributed.
The cross sectional shape of air channel is unlimited, as long as ventilatory function may be implemented.
The working principle of the application is further illustrated by taking embodiment 1 as an example are as follows:
Be threadedly coupled in use, suspension hook 03 passes through hanging ring with hemisphere 02, and by 04 locking positioning of locking nut, suspension hook 03 and
Hemisphere 02 is connected as one.Hemisphere 02 can arbitrarily rotate in half ball 011, under gravity, can be certainly when lifting weight
Phenomena such as dynamic center-of-gravity regulating, is overlapped the center line of suspension hook 03 and the center line of hanging ring 01, and suspension hook 03 does not generate deflection, card plug,
Suspension hook and hanging ring uniform wear, and the mating surface of suspension hook and hanging ring is spherical surface, forced area is big, and load difference is uniform, further
Ground reduces the concentrated wear of suspension hook and hanging ring.Hemisphere 02 is equipped with venthole, and hemisphere is during rotary aligning, air warp
Venthole 022 enters the mating surface of hemisphere 02 and half ball 011, forms one layer of air film between mating surface, further reduces
The abrasion of suspension hook and hanging ring, and vacuum coherent condition will not be generated between two mating surfaces with the extension of use time, it produces
Raw movement interference.
Not doing the part illustrated in above instructions is the prior art, or has both been able to achieve by the prior art.
