The invention provides a novel rotary joint with a simple structure and easy operation. The rotary joint comprises a sphere (1) and a main body (2), wherein a connecting passage (3) is arranged in the sphere (1) and the main body (2), the sphere (1) is provided with a spherical joint (7), an outlet of the connecting passage (3) is arranged at the end part of the spherical joint (7), a sphere holding cavity (8) distributed in a spherical surface shape is arranged in the main body (2), and the sphere (1) is arranged in the sphere holding cavity (8); the sphere (1) provided by the invention is provided with the spherical joint (7), and the sphere can very freely rotate in the holding cavity by the characteristics of the spherical structure when the spherical joint (7) is arranged in the sphere holding cavity (8), so that the rotary joint can fit for pipeline connections of a plurality of steering angles, thereby reducing the purchase amount of the joint, and the purchase cost is reduced as a result.
Description
Technical field [0001] The invention relates to a joint device, in particular to a new type of rotary joint. Background technique [0002] At present, the joints sold on the market generally belong to a fixed structure. When the pipe needs to be steered and adjusted, joints of various angles are required for connection. Therefore, there are many types of joints and it is not easy to store. Summary of the invention [0003] In order to solve the above technical problems, the present invention provides a new type of rotary joint with a simple structure and easy operation, comprising a ball and a main body. The connecting channel is located in the ball and the main body. The ball has a ball joint and the end of the ball joint has a connecting channel. The main body has a spherical accommodating cavity distributed in a spherical shape. The sphere is placed in the accommodating cavity. The upper and lower parts of the sphere are equipped with a sealing ring A and a sealing ring B. The ...
