DETAILED DESCRIPTION OF THE INVENTION

[0014] The following description is merely preferred embodiments of the present invention which is not intended to limit the protection scope of the present invention. The present invention will be further described with reference to the drawings and embodiments hereinafter.

Embodiment

[0015] As shown in FIG. 1 to FIG. 3, a connecting union joint with smart connection of an easy-flowing pipe system includes a joint body 10. The joint body 10 is a two-end through structure which may be a straight-through structure or an elbow structure. An end of the joint body 10 is provided with a pipe connecting device. The pipe connecting device includes a sliding base 20, a snapping tooth piece 21, a reset spring 22, a spring pad 23 and a snapping ring 24. The sliding base 20 is slidably arranged inside the joint body 10. The sliding base is internally provided with a through hole for the pipe to pass. The joint body 10 is internally provided with a snap slot 11. The snapping ring 24 is snapped within the snap slot 11. The sliding base 20 is configured with a snapping end surface 203 for snapping with the snapping ring 24, so that the sliding base 20 can be prevented from sliding out of the joint body 10 through a snapping and positioning between the snapping end surface 203 and the snapping ring 24. The spring pad 23 is fixedly arranged inside the joint body 10. The spring pad 23 is provided with a first convex part 231. A front end surface of the sliding base 20 is provided with a second convex part 202. One end of the reset spring 22 is sleeved around the first convex part 231. The other end of the reset spring is sleeved around the second convex part 202. The reset spring 22 enables the sliding base 20 to return to its original position after sliding, namely, the snapping end surface 203 on the sliding base 20 abuts against the snapping ring 24 the through an elastic force. The sliding base 20 is evenly provided with a plurality of through openings 201 that cut through an inner end surface and an outer end surface of the sliding base. The through openings 201 are internally configured with steps, while the snapping tooth piece is also configured with steps. The steps are matched with each other. An outer side surface of the snapping tooth piece has an inclined structure which is snapped in the through opening 201. The snapping tooth 211 of the snapping tooth piece 21 deeply extends into an inner wall of the sliding base 20 and is snapped with an outer peripheral surface of the pipe. The structure that the snapping tooth 211 is snapped with an outer peripheral surface of the pipe is more stable and has a longer service life than the existing structure. An inner wall of the joint body 10 is provided with a moving area 12 for allowing the snapping tooth piece 21 to move therein. The moving area 12 is an inclined surface that inclines downward. When the sliding base 20 is pushed inwardly, the snapping tooth piece 21 is pushed to rotate downward by the through opening 201 and rotate into the inclined surface, so that the snapping tooth 211 can be separated from the outer peripheral surface of the pipe, and thus the pipe can be disassembled easily. When the pipe needs to be assembled, the sliding base 20 is also pushed inward, so that the snapping tooth piece 21 would rotate into the moving area 12. At this time, the snapping tooth are held within the through opening 201. After the pipe is inserted, the sliding base 20 is released. Under the action of the reset spring 22, the sliding base 20 will move toward the outer side. Meanwhile, the through opening 201 would drive the snapping tooth piece 21 to return back to the original position and the snapping tooth 211 would be snapped with the outer peripheral surface of the pipe. After the sliding base 20 moves for a certain distance, the snapping end surface 203 on the sliding base 20 would be snapped with a snapping ring 24, so that the positioning function is achieved.

[0016] The joint body 10 is internally provided with a support pad 30, a first seal ring 31 and a second seal ring 32. The support pad 30 is fixedly arranged inside the joint body 10. One end of the first seal ring 31 abuts against the support pad 30. The other end of the first seal ring abuts against the end surface of the spring pad 23. One end of the second seal ring 32 abuts against the end surface of the support pad 30. The other end of the second seal ring 32 abuts against the inner bottom surface of the joint body 10. The first seal ring 31 and the second seal ring can increase the sealing in use.
