Detailed Description

The embodiments of the present invention will be described in detail below, examples of which are illustrated in the accompanying drawings, and the embodiments described below by referring to the drawings are exemplary and intended to explain the present invention so that the technical solutions of the present invention can be more easily understood and grasped, and cannot be construed as limiting the present invention.

Example (b):

a ball head assembly structure is shown by combining a figure 1 and a figure 2 and comprises a ball head pin 1, a connecting arm 2, an inner ball head tile 3, an outer ball head tile 4, an upper gasket 5, a lower gasket 6 and a spring 7. Two to three, preferably two, inner ball head tiles 3 are preferably matched with two outer ball head tiles 4. This can improve the ease of assembly.

And by taking the orientation shown in the drawing as reference, a threaded column 12 is arranged at the outer end part of the ball stud 1, the threaded column 12 is positioned above, and a through hole 13 which horizontally penetrates through the threaded column 12 is arranged on the threaded column 12. Therefore, the ball stud 1 can be in threaded connection, and the through hole 13 can be used before assembly, and the rod is inserted into the through hole 13 to adjust the flexible degree of the movement of the test ball. The function of this through-hole 13 can also be used for fastening other fittings in a bayonet-like manner.

The connecting arm 2 is provided with a ball head seat 8 for assembling the ball head pin 1. The upper part and the lower part of the ball head seat 8 are provided with openings, the middle part is provided with a cavity, the cavity can be assembled with the ball head part of the ball head pin 1, the inner ball head tile 3, the outer ball head tile 4, the upper gasket 5, the lower gasket 6 and the spring 7. The connecting arm 2 is provided with a plurality of mounting holes 14 at equal intervals. The mounting holes 14 can adjust the mounting and fixing positions of the connecting arm 2 on other accessories.

The bulb end of the bulb pin 1 is attached to two inner bulb tiles 3 arranged on the left and right sides, the outer sides of the two inner bulb tiles 3 are respectively attached to two outer bulb tiles 4, and the attaching surfaces of the inner bulb tiles 3 and the outer bulb tiles 4 are conical surfaces. The upper part of the ball end is a neck part, and the lower end is a plane end. The diameter of the cone opening of the joint of the inner ball head tile 3 and the outer ball head tile 4 is smaller than that of the end part of the ball head pin 1 close to the neck part of the ball head pin 1. Namely, by utilizing the conical surface structure, when the ball pin 1 and the inner ball head tile 3, and the inner ball head tile 3 and the outer ball head tile 4 are movably worn, enough space is lubricated, and meanwhile, the contact surface of the ball joint can be freely adjusted. The ball seat 8 is filled with lubricating oil or lubricating grease, so that the ball seat is smooth in movement and not easy to wear, and the service life is greatly prolonged.

The upper gasket 5 is clamped in the ball head seat 8 and supports the inner ball head tile 3 and the outer ball head tile 4, the spring 7 is arranged between the upper gasket 5 and the lower gasket 6, and the bottom opening edges of the lower gasket 6 and the ball head seat 8 are fixed with each other. The spring 7 is a tower spring 7, and has a small end 71 and a large end 72, wherein the small end 71 abuts against the upper gasket 5, and the large end 72 abuts against the lower gasket 6. With the structure, the arrangement of the tower-shaped spring 7 enables the bottom of the tower-shaped spring 7 to be more stable, and the movement allowance of the upper gasket 5 is larger, so that the movement and the vibration buffering of the ball stud 1 are facilitated. Therefore, the structure can effectively improve the flexibility of the ball stud 1.

For better lubrication and wear reduction, better guiding of lubricating oil or lubricating fluid is required, and the inner side wall and the outer side wall of the outer ball head tile 4 are provided with oil way grooves 9. The oil groove 9 is rectangular. Therefore, lubricating oil can enter the inner side and the outer side of the outer ball head tile 4, and the lubricating effect is further improved.

In order to further improve the lubricating effect of the bottom, the bottom end local edge of the outer ball head tile 4 is provided with a protrusion 10, and the protrusion 10 abuts against the upper gasket 5 to enable the bottom end local edge of the outer ball head tile 4 to leave a gap. The gap can also contain lubricating oil, and the lubricating effect is improved.

In order to avoid the entry and contamination of foreign matters, the space between the upper opening of the ball head seat 8 and the neck of the ball stud 1 is sealed by a dust cover 11. Therefore, the whole structure is very reliable, the use can be carried out for a long time, and the service life is prolonged.

Of course, the above is only a typical example of the present invention, and besides, the present invention can also have other various specific embodiments, and all technical solutions adopting equivalent replacement or equivalent transformation are all within the scope of the present invention as claimed.
