A first through hole for the first pipe fitting to pass through is provided in the first joint, a second through hole for the second pipe fitting to pass through is provided in the second joint, the second end of the first joint is welded to the outer wall of the first pipe fitting, and the second end of the second joint is welded to the outer wall of the second pipe fitting. The outer circumference of the first joint is provided with a first step, the outer circumference of the second joint is provided with an external thread, and the outer sleeve nut is provided with a step hole, the step hole includes a first hole and a second hole that are connected, the diameter of the first hole is smaller than the diameter of the second hole, and a second step is formed between the first hole and the second hole, and the second hole is provided with an internal thread. When the outer sleeve nut is screwed on the first joint and the second joint, the first end of the first joint passes through the first hole, and the first step abuts against the second step, and the first end of the second joint is inserted into the second hole and is screwed with the internal thread of the outer sleeve nut through the external thread. However, during the use of the above-mentioned pipe joint assembly, since the size of its inner diameter is fixed, the maximum amount of water that can flow through the above-mentioned pipe joint assembly per unit time is constant and cannot be adjusted as needed. Summary of the invention

[0003] In view of this, the purpose of the utility model is to provide a flow rate control and adjustable combined pipeline joint, which has the advantage that the maximum amount of water that can flow through per unit time can be adjusted according to needs.

[0004] In order to solve the above technical problems, the technical solution of the utility model is: a flow rate control and adjustable combined pipeline joint, including a water inlet joint and a water outlet joint, the water inlet joint is provided with an external thread at the outer wall of the water outlet end, and the water inlet end of the water outlet joint is provided with an internal thread at the outer wall, the water inlet end of the water outlet joint is sleeved on the outside of the water outlet end of the water inlet joint, and the internal thread is screwed and fixed with the external thread, the water outlet end of the water inlet joint is provided with a plurality of elastic paddles, and the plurality of elastic paddles are evenly distributed along the circumference of the water inlet joint, a control retaining ring is provided inside the water outlet joint, and the control retaining ring is provided with an annular guide inclined surface near the water inlet joint, when the annular guide inclined surface touches the elastic paddle, the control retaining ring can drive the elastic paddle to bend to one side of the central axis of the water inlet joint, and the outer side of the water outlet end of the water outlet joint is rotatably connected with a connecting sleeve.

[0005] Through the above technical solution, during the use of the above pipe joint, if it is necessary to reduce the maximum amount of water that can flow through per unit time, it is only necessary to rotate the water outlet joint clockwise so that the water outlet joint is close to the water inlet joint. At this time, the control retaining ring located inside the water outlet joint squeezes the elastic paddle through the annular guide slope, so that the elastic paddle is bent to the side of the central axis of the water inlet joint, so that the inner diameter of the water outlet end of the water inlet joint is reduced. If it is necessary to increase the maximum amount of water that can flow through per unit time, it is only necessary to rotate the water outlet joint counterclockwise so that the water outlet joint is away from the water inlet joint. At this time, the control retaining ring located inside the water outlet joint gradually moves away from the elastic paddle, and the elastic paddle gradually recovers its deformation under the action of its own elasticity, so that the inner diameter of the water outlet end of the water inlet joint is increased. The pipe joint configured as above has the advantage that the maximum amount of water that can flow through per unit time can be adjusted as needed during use.

[0006] Preferably, the control baffle ring is provided with an annular guide slope away from the water inlet joint, and the annular guide slope is used to guide the water flow to pass through the center of the control baffle ring.

[0007] Through the above technical solution, the annular guide slope can guide the water flow to pass through the center of the control baffle ring, thereby reducing the influence of the control baffle ring on the water flow velocity.

[0008] Preferably, the control retaining ring has a plurality of water passing holes evenly distributed along the circumferential direction, and two ends of the water passing holes respectively penetrate the annular guide inclined surface and the annular flow guide inclined surface.

[0009] Through the above technical solution, a plurality of water holes are opened on the control baffle ring, which can further reduce the influence of the control baffle ring on the water flow velocity.

[0011] Through the above technical solution, a deformation notch is provided at the side wall of the control retaining ring, so that when the control retaining ring is installed, the control retaining ring can be squeezed to reduce the outer diameter of the control retaining ring, so that the control retaining ring can be more conveniently installed in the water outlet joint. The annular installation groove cooperates with the installation ring to limit the control retaining ring, so that the control retaining ring is not easy to slide along the axial direction during the use of the above pipe joint.

[0012] Preferably, an elastic connecting cloth piece is provided between two adjacent elastic paddles.

[0013] Through the above technical solution, an elastic connecting cloth piece is arranged between two adjacent elastic paddles, so that the gap between the two elastic paddles can be blocked, thereby improving the control efficiency of the water flow.

[0014] Preferably, a sealing ring groove 1 is provided at the outer wall of the water outlet end of the water inlet joint, a sealing ring 1 is nested in the sealing ring groove 1, and the outer ring of the sealing ring 1 is tightly pressed against the inner wall of the water outlet joint.

[0016] Preferably, a rotating ring groove is provided at the outer wall of the water outlet end of the water outlet joint, and a rotating convex ring is provided at the inner wall of the connecting sleeve, and the rotating convex ring is rotatably connected in the rotating ring groove.

[0018] Preferably, a second sealing ring groove is provided at the outer wall of the water outlet end of the water outlet joint, a second sealing ring is nested in the second sealing ring groove, and the outer ring of the second sealing ring is tightly pressed against the inner wall of the connecting sleeve.
