Description

Technical Field

[0002] A ball stud consists of a spherical bolt head and a threaded shank. This special bolt head is designed to allow for quick assembly, allowing the components to be put together with a certain degree of mobility.

[0003] For example, the announcement number CN101839235A discloses a ball head screw locking device for an air compressor, which connects the ball head and the screw rod through the external threads at the upper ends thereof with a connecting rod axially provided with internal threads, a cylindrical cavity is provided at the lower end of the connecting rod, a screw sleeve matching the cylindrical cavity is fixed on the ball head and the screw rod, a pressure cap is provided at the lower end of the connecting rod to press the screw sleeve, and a closed annular cavity is formed at the joint of the connecting rod, the pressure cap and the screw sleeve, a certain amount of liquid plastic is filled into the cavity, and the liquid plastic is expanded by rotating the pressure regulating screw, so that a pair of opposite forces are generated between the screw sleeve and the pressure cap and transmitted to the ball head, the screw rod and the connecting rod, and when the air compressor is stamping, the purpose of locking the connecting rod and the ball head and the screw rod threads can be achieved, there is no displacement between each other, the locking force is strong, and the locking is reliable; when the mold height needs to be adjusted, the pressure regulating screw is loosened to release the pressure, and the thread gap between the connecting rod and the ball head and the screw rod can reach a normal state, and the purpose of adjusting the mold height can be achieved.

[0004] It can be seen from the above-mentioned public scheme that when the ball stud connects the installation object and the installed object, it is mostly limited by the thread line. However, after long-term use, the ball stud column is prone to loosening and easy to fall off, thereby affecting the stability of the installation connection between the installation object and the installed object, thereby affecting use.
