The specific embodiment:
In order more to be expressly understood technology contents of the present utility model, describe in detail especially exemplified by following examples.
As Fig. 1, Fig. 2 and shown in Figure 3, that the utility model ball pivot 1 comprises is metal-cored 2, elasticity original paper 3 and supporting blade 4, described metal-cored 2 comprise main shaft 21 and at least one boss 5 that is arranged on the outerface of spindle, described elastic element 3 is cast in the outside face of described metal-cored middle part, described supporting blade 4 is arranged on the outside of elastic element 3, be used to surround the elasticity original paper, being provided with of boss 5 can prevent metal-cored 2 in elasticity original paper 3 about string moving.
Described metal-cored main shaft 21 two ends are that 6, two support portions 6, support portion respectively are provided with ball pivot fixed orifice 7, are used for fixing ball pivot, and the corner 8 of described support portion 6 is set to fillet structure.
Some cushion holes 9 are set in the described elastic element 3; in the specific embodiment; described elastic element 3 is the antivibration wear resistant elastomeric material; in the elastic element 3 up and down the position respectively form a cushion hole 9; when applied external force is big; 9 pairs of application forces of cushion hole can produce buffering effect, are unlikely to damage ball pivot 1, and other connecting portion in the whole articulated system is also played a protective role.
Described supporting blade 4 is made up of two arc metal plates, forms two slots 10 in the junction, prevents stress deformation under great force.
Described metal-cored main shaft 21 is made one with described boss 5, forms metal-coredly 2, and rigidity is stronger.
Fig. 4 is the metal-cored block diagram in the utility model ball pivot preferred embodiment, metal-cored 2 main shaft 21 is the square cylinder structure among the figure, described boss 5 is wholely set on the outside face of described metal-cored main shaft 21, described boss 5 is the circular rings body structure, one is looped around on described metal-cored main shaft 21 outside faces, and four boss evenly are set in the present embodiment at interval.
