Description

Three-axis spherical universal structure

This creation relates to a three-axis spherical universal structure, especially a three-axis spherical universal structure with a main body that has a gap that can be opened to a preset angle.

The conventional spherical gimbal structure (such as a ball head) is made of metal. During assembly, the ball is first placed through the bottom of the main body of the head and then the base, and then a ball is locked from the side of the base. Fix the screws to fix the base to prevent the main body of the gimbal and the base from detaching from each other. Lock the screw knob from the side of the ball gimbal. Use the locking screw knob to press the concave position on the upper part of the base and push the base upward. The ball is kept stationary, and the base can be rotated horizontally by loosening the screw knob. The disadvantage of this conventional structure is that it is made of metal and is heavy in weight. When the fixing screws are missing or loose and the base is not fixed, when the screw knob is loosened to a certain extent, the base and the main body of the gimbal will be separated. If the separation is loose, if there is equipment connected above the gimbal, it may cause damage to the equipment.

A conventional spherical gimbal structure (for example, a ball head with a notch) uses a fixed component to control the size of the notch to clamp or loosen the sphere. However, in the conventional design, a fastener is provided below the sphere to connect to the ball head. On other items, when the fasteners are tightened, the direction of the ball head with a notch is fixed and cannot be adjusted horizontally.

In order to overcome the problems that the conventional spherical universal structure is too heavy and loose, causing damage to other connecting devices or the inability to adjust the direction horizontally, this invention provides a three-axis spherical universal structure, including: a main body, a sphere and a rotating shaft. Among them, the main body is provided with a sphere accommodating part and a rotating shaft accommodating part that are adjacent up and down. The sphere accommodating part is provided with a sphere accommodating part opening upward, and the rotating shaft accommodating part is provided with a rotating shaft accommodating part opening downward. A gap is formed from the sphere. The opening of the accommodating part extends to the opening of the rotating shaft accommodating part. The sphere accommodating part and the rotating shaft accommodating part are connected to the external space through the gap. A fixing component is provided on the main body close to the gap and the opening of the sphere accommodating part. The rotating shaft can be in the rotating shaft container. Rotate horizontally in the setting part; when the main body is stretched from the notch to the preset angle, the rotating shaft is placed in the rotating shaft receiving part, and the ball is placed in the ball receiving part, so that the two parts of the main body are close to each other from the notch, and by locking The fixed component narrows the gap, and the ball receiving part and the rotating shaft receiving part clamp the ball and the rotating shaft respectively to push the ball downward, and then the ball and the rotating shaft are pushed against each other so that the ball cannot rotate, and the rotating shaft cannot be horizontal relative to the main body. Rotation, conversely, both the sphere and the shaft can rotate. This creation can use plastic materials to solve the problem of heavier weight. The gap can be used to prevent the ball from falling off and causing damage to the equipment above the head. The setting of the rotating shaft increases the horizontal rotation function.

When zoomed out, the sphere receiving part and the rotating shaft accommodating part clamp the sphere and the rotating shaft respectively to push the sphere downward, and then make the sphere and the rotating shaft push against each other so that the sphere cannot rotate, and the rotating shaft faces each other. When the body cannot rotate horizontally and the fixing component is loosened to make the gap larger, the ball is loosened from the ball receiving portion and the rotating shaft is released from the rotating shaft receiving portion, and the ball and the rotating shaft are loosened.
