[0015] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.
[0016] like Figure 1 、 Figure 2 、 Figure 3As shown, the adjustable joint includes a joint body 1, the joint body 1 is provided with two openings 2 for connecting pipes, the joint body 1 has a flow pipe 12 for fluid circulation, the lower end of the joint body 1 is provided with a rotatable rotating member 3, a bearing is provided between the rotating member 3 and the joint body 1, the joint body 1 is provided with a fixing member 4, the fixing member 4 is provided with an opening 2 for connecting pipes, the joint body 1 is provided with a non-return assembly for non-return, the non-return assembly is composed of a water stop Part 6, water retaining part 7, connecting rod 8 and reset spring 9, the joint body 1 is provided with a water hole 10 connected to the interior of the fixing part 4, the inner wall of the rotating part 3 is provided with a fixing part 5, the fixing part 5 and the rotating part 3 are integrally formed, the fixing part 5 has a water hole 11 for fluid circulation, the water retaining part 7 and the water stop part 6 are connected by a connecting rod 8, the water stop part 6 is used for checking the pipe connected to the fixing part 4, and the water retaining part 7 is used for checking the pipe connected to the upper end of the joint body 1.
[0017] To elaborate further, the pipe connected to the opening 2 at the upper end of the joint body 1 is the water inlet pipe, and the pipe connected to the rotating part 3 is the water outlet pipe. When the fluid flows in from the pipe of the fixed part 4, pressure is applied to the water stop part 6, the water stop part 6 and the water retaining part 7 move downward, and the reset spring 9 is in a compressed state, so that the water hole 10 is in a flow state. At the same time, the fluid flows in from the water inlet pipe of the joint body 1, and the water hole 2 11 is in a flow state. When the two pipes stop flowing, the connecting spring rebounds and re-seals the water hole 10 and the water hole 2 11 to prevent the fluid flowing into the water outlet pipe from flowing back, which has a check function.
