Embodiment Construction

[0022] In order to have a further understanding of the purpose, structure, features, and functions of the present invention, the following detailed descriptions are provided in conjunction with the embodiments.

[0023] Certain terms are used in the description and claims to refer to particular elements. Those of ordinary skill in the art will appreciate that manufacturers may refer to the same element by different terms. The specification and claims do not use the difference in name as a way to distinguish components, but use the difference in function of components as a criterion for distinguishing. "Include" mentioned throughout the specification and claims is an open term, so it should be interpreted as "including but not limited to".

[0024] refer to Figure 1 to Figure 5 As shown, it discloses a schematic structural diagram of a ball joint device according to an embodiment of the present invention. The ball joint device 100 includes a ball joint part 1, a connecting p...

Abstract

The invention provides a ball joint device, comprising a ball joint part and a connecting part, the ball joint part has a first spherical joint part, and the first spherical joint part has a first surface; the connecting part has a first receiving part, a first The fixing part, the first arc surface and the second arc surface, the first receiving part cooperates with the first fixing part so that the first spherical joint part is rotatably arranged on the connecting part; wherein, when the first spherical joint When the portion is disposed on the connecting portion, the first arc surface and the second arc surface interfere with the first surface respectively, and the first arc surface and the second arc surface do not match. In this way, the problem of uneven force caused by component tolerances can be overcome.

Description

technical field [0001] The invention relates to the field of mechanical active connections, in particular to a connection structure with ball joints. Background technique [0002] At present, the ball joint is generally composed of a fixed piece, a movable adjustment ring and an adjustment screw. The passive manual adjustment screw is used to generate friction to achieve a 360-degree free rotation of the ball joint while having a fast connection effect. , to rotate and can be relatively fixed in a certain state. However, the above-mentioned structure may have the problem of loosening of the adjustment screw and a reduction in the friction force after long-term use, and repeated adjustments must be made manually, which is a problem for devices that do not need to change the torque. [0003] Another type of ball joint structure without an adjustment ring uses the receiving part and the fixed part to cooperate and lock through a plurality of connecting parts to generate fricti...
