DETAILED DESCRIPTION

[0016] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0017] Reference Figure 1-Figure 4 As shown, a multi-angle rotating quick connector comprises a first connecting section 1, a connecting pipe 2 and a second connecting section 3, one end of the second connecting section 3 is rotatably sleeved on one end of the connecting pipe 2; a ball 4 is fixedly installed at one end of the first connecting section 1, and a through hole is provided on the ball 4, and a connecting block 5 is installed at one end of the connecting pipe 2, and a spherical groove 6 is provided at the end of the connecting block 5 away from the connecting pipe 2, and the ball 4 is roamingly embedded in the spherical groove 6, and a sealing groove 7 is provided on the inner wall of the spherical groove 6, and a sealing component is provided in the sealing groove 7; the first connecting section 1 and the second connecting section 3 of the connector are respectively connected to one end of two pipelines, and the second connecting section 3 can rotate with the connecting pipe 2, so that the second connecting section 3 can rotate around the first connecting section 1, and when installing , one end of the pipeline can be found by rotating the second connecting section 3; the connecting pipe 2 is installed on the sphere 4 through the connecting block 5. Under the action of the spherical groove 6, the connecting block 5 can move on the sphere 4 along the arc surface of the sphere 4. When the connecting block 5 moves, it can drive the connecting pipe 2 and the second connecting section 3 to move together. The first connecting section 1 is connected to the connecting pipe 2 and the second connecting section 3 through the through hole on the sphere 4. The angle between the first connecting section 1 and the second connecting section 3 can be changed by moving the connecting block 5 on the sphere 4, so that the angle between the first connecting section 1 and the second connecting section 3 can be adjusted according to the angle between the two pipelines. It can be used to connect two pipelines that are not perpendicular to each other, effectively improving the practicality of the joint.

[0018] An arc groove 8 is provided on the inner wall of the sealing groove 7. The sealing assembly includes an annular sealing airbag 9 arranged in the sealing groove 7, an arc push block 10 horizontally slidably installed in the arc groove 8, and a moving part for driving the arc push block 10 to move. The arc push block 10 is fixedly connected to the sealing airbag 9, and the sealing airbag 9 is sleeved on the sphere 4. A threaded hole connected to the arc groove 8 is provided on the surface of the connecting pipe 2. The moving part includes a threaded rod 11 threadedly inserted in the threaded hole and a rotating rod 12 fixedly installed at one end of the threaded rod 11. The end of the threaded rod 11 away from the rotating rod 12 is rotatably connected to the arc push block 10; when the angle between the first connecting section 1 and the second connecting section 3 is adjusted, the rotating rod 12 is rotated to rotate. The rotating rod 12 drives the threaded rod 11 to rotate. Under the action of the threaded hole, the threaded rod 11 drives the arc-shaped push block 10 to move toward the sealing airbag 9, thereby squeezing the sealing airbag 9. The sealing airbag 9 will be deformed, so as to be in tight contact with the inner wall of the sealing groove 7 and the surface of the sphere 4. After the sealing airbag 9 contacts the sphere 4, the friction between the sphere 4 and the sealing airbag 9 can be increased. Under the action of the friction force, the connection block 5 can be limited from rotating on the sphere 4 to ensure the stability of the joint when in use; at the same time, the sealing airbag 9 blocks the gap between the sphere 4 and the connection block 5 to ensure the sealing between the sphere 4 and the connection block 5, and avoids leakage at the connection between the sphere 4 and the connection block 5 when the joint is in use.

[0019] A fixing ring 13 is fixedly installed on the side of the connecting pipe 2, and a plurality of positioning grooves are opened on the fixing ring 13. A torsion spring 14 is sleeved on the threaded rod 11. A positioning ring 15 is fixedly installed on one end of the torsion spring 14, and the other end is fixedly connected to the rotating rod 12. A plurality of positioning rods 16 are fixedly installed on the positioning ring 15, and one end of the plurality of positioning rods 16 is respectively inserted into a plurality of positioning grooves; after the threaded rod 11 is rotated to drive the arc-shaped push block 10 to contact the sealing airbag 9, the positioning ring 15 is then rotated in the same direction as the threaded rod 11, so that the torsion spring 1 4 undergoes torsional deformation, and inserts the positioning rod 16 on the positioning ring 15 into the positioning groove on the fixing ring 13. Under the torsion of the torsion spring 14, one end of the torsion spring 14 applies a rotational force to the rotating rod 12. Under the action of the force, the threaded rod 11 tends to rotate, and under the rotational trend, the threaded rod 11 tends to approach the sealing airbag 9, thereby preventing the sealing airbag 9 from applying a reaction force to the threaded rod 11 when the joint is in use, causing the threaded rod 11 to become loose, thereby affecting the sealing between the ball 4 and the connecting block 5.

[0020] A retaining ring 17 is fixedly mounted on the sphere 4 , and one end of the through hole is located in the retaining ring 17 . When the connecting block 5 rotates on the sphere 4 , the retaining ring 17 can prevent the connecting block 5 from blocking the through hole.

[0021] A sealing gasket is fixedly mounted on the arc-shaped push block 10 , and the sealing gasket is in sealing sliding contact with the inner wall of the arc-shaped groove 8 , so that the sealing gasket can increase the sealing performance between the arc-shaped push block 10 and the arc-shaped groove 8 .

[0022] In the utility model, the connecting pipe 2 is installed on the sphere 4 through the connecting block 5. Under the action of the spherical groove 6, the connecting block 5 can move on the sphere 4 along the arc surface of the sphere 4. By moving the connecting block 5 on the sphere 4, the angle between the first connecting section 1 and the second connecting section 3 can be changed, so that the angle between the first connecting section 1 and the second connecting section 3 can be adjusted according to the angle between the two pipelines. It can be used to connect two pipelines that are not perpendicular to each other, effectively improving the practicality of the joint.
