[0017] Figure 1 It is the sectional view schematic diagram of the first embodiment of the utility model.

[0018] Figure 2 It is Figure 1 It is the enlarged schematic view of A in the middle. PREFERRED EMBODIMENT

[0019] The utility model discloses a stable high -life double ball bowl structure suspension ball hinge, including ball seat 1 and ball pin 2, further include installation groove 11, be located in ball seat in, ball head 21, be located in the one end of ball pin and enter the installation groove, inner ball bowl 3, install in installation groove with ball head contact between the outer wall of inner ball bowl and installation groove inner wall, oil nozzle 5, be located in the bottom of ball seat and be used to oil injection into installation groove. When the ball bowl produces trace wear, can automatically compensate the gap, has guaranteed the torque of ball hinge, has improved the service life of ball hinge, and the specific material of inner ball bowl can be tpu, has excellent elasticity, and the carrying capacity and anti -impact performance are outstanding, make ball bowl in the use process to the connecting component play better buffering protection effect, reduce the wear and tear and damage due to the vibration and impact, improve the service life of ball hinge. TPU has good weather resistance, can adapt to various climate and environmental conditions, is not easy to age, crack and deformation, under different temperature, humidity and illumination etc. Environmental factor, TPU ball bowl structure can keep stable performance. Meanwhile TPU has good flexibility, for some ball bowl structure that needs to work under complex working conditions, the flexibility of TPU can make it better play the connection and support effect, reduce stress concentration, improve the reliability of ball hinge. Moreover can use in various oils long -term and not damage.

[0020] In the embodiment, as shown in the drawing, further include oil groove 211, be located in the circumferential outer wall of ball head, and along the latitude direction of ball head extension. Adopt the oil nozzle lubrication mode, and mill oil groove on ball pin simultaneously, like this oil can lubricate continuously lubricate ball pin, reduce the wear and tear of ball pin and ball bowl, improve the durable life of ball head.

[0021] In the embodiment, as shown in the figure, the installation groove is of a structure that the bottom is larger and the top is gradually tapered.
