This application claims the priority of Chinese patent application No. 201920677298.8, filed on May 13, 2019, which is incorporated herewith by reference.

BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates to a ball head, and more particularly, to a ball head having a main body with a notch capable of being expanded to a predetermined angle.

2. The Prior Arts

Generally, conventional ball heads are made of metal material or plastic material. For the metal ball head, during assembly, a ball body and a base are sequentially placed into a main body through a bottom thereof, and then a screw is screwed into the ball head from a side surface thereof. By screwing the screw against a recess position on an upper portion of the base, the base is pushed upward against the ball body, thereby making the ball body non-rotatable. The disadvantage thereof is that the metal material is too heavy.

For the plastic ball head, during assembly, the ball body can be squeezed from a top thereof into the main body due to the elasticity of plastic material, and then the ball body is held against by a side fastener, thereby making the ball body non-rotatable. The disadvantage thereof is that the ball body is easy to fall from a height due to unexpected detachment, thereby causing a damage to the equipment installed on the ball head.

SUMMARY OF THE INVENTION

In order to overcome the heavy weight problem of the conventional ball heads or the falling risk of the ball body thereof, the present invention provides a ball head, wherein a main body is provided with a ball body accommodating portion and a fastener accommodating portion. The main body is provided with a notch extending from a ball body accommodating opening to a fastener accommodating opening. The notch of the main body can be expanded to a predetermined angle, so that the fastener and the ball body are sequentially and respectively placed into the fastener accommodating portion and the ball body accommodating portion, and then both sides of the notch are forced to be close to each other. The notch can be constrained by locking a fixing assembly tight and thus the ball body is non-rotatable, while the fixing assembly can also be loosened and thus the ball body is rotatable. In the present invention, by using plastic material, the heavy weight problem can be solved; and further by providing a notch, the ball body can prevent from falling off due to the unexpected detachment, thereby avoiding the damage to the equipment installed on the ball head.

The technical solution adopted by the present invention to solve the technical problems is as follows. The present invention provides a ball head including a main body, a ball body, and a fastener. The main body is provided with a ball body accommodating portion and a fastener accommodating portion, which are adjacent to each other in an up-and-down direction. The ball body accommodating portion is formed with a ball body accommodating opening extending upward to an external space, and the ball body accommodating opening has a diameter smaller than that of the ball body accommodating portion. The fastener accommodating portion is formed with a fastener accommodating opening extending downward to the external space, and the fastener accommodating opening has a diameter smaller than that of the fastener accommodating portion. The main body is provided with a notch extending from the ball body accommodating opening to the fastener accommodating opening. The ball body accommodating portion and the fastener accommodating portion are communicated with the external space through the notch. A fixing assembly is disposed at the notch at a position close to the ball body accommodating opening. The ball body is provided with a threaded rod extending outward therefrom. A platform is disposed on the threaded rod and provided with a platform nut at a center of the platform. The threaded rod and the platform nut are coupled with each other and rotatable with respect to each other, so as to adjust a position of the platform relative to the threaded rod. The notch of the main body can be expanded to a predetermined angle, so that the fastener is placed into the fastener accommodating portion, the ball body is placed into the ball body accommodating portion, and the threaded rod penetrates outward through the ball body accommodating opening, and then both sides of the notch of the main body are forced to be close to each other. The notch can be further contracted by locking the fixing assembly tight, such that the ball body accommodating portion clamps the ball body and thus the ball body is non-rotatable. The notch can also be expanded by loosening the fixing assembly, such that the ball body accommodating portion releases the ball body and thus the ball body is rotatable.

Preferably, the main body is provided with a threaded rod accommodating opening opposite to the notch, and the threaded rod accommodating opening extends from the ball body accommodating opening to a proper position on the main body.

Preferably, the fastener is a nut coupled with a first object through the fastener accommodating opening.

Preferably, the fastener is a screw coupled with a second object through the fastener accommodating opening.

The present invention has the beneficial effects that the weight of the ball head can be reduced, the ball body of the ball head can prevent from falling off, and the ball head can be coupled with other objects through a fastening screw or nut, thereby increasing the portable convenience, the using safety, and the using diversity.
