The traditional fixed angle elbow cannot release the torsion, twist and over-bending fatigue phenomenon of the hose during installation, and the traditional anti-torsion and anti-knot joint is connected to the main elbow by reverse core, the reverse core is fixed by reverse thread and glue, and the thread of the reverse core of the hose is often loose during installation, causing joint leakage; in addition, the nut of the traditional movable nut elbow is fixed after being screwed, and the elbow is also fixed, so the direction cannot be adjusted. UTILITY MODEL CONTENTS

[0003] The utility model solves the technical problem to provide a multi -angle freely regulated elbow, which is applied to the joint for connecting waterway pipe and braided hose, and realizes multi -angle freely regulated.

[0004] The technical solution of the utility model provides a multi -angle freely regulated elbow, which comprises a nut, a right-angle elbow body, an O-shaped ring, a sealing ring, an external thread joint, a C-shaped clamp spring and a movable core, wherein,

[0005] The right-angle elbow body comprises a horizontal shaft and a vertical shaft, a first clamping groove and a first sealing groove are arranged on the outer peripheral wall of the horizontal shaft, the first clamping groove and the first sealing groove are sequentially and spaced apart towards the vertical shaft, the C-shaped clamp spring is arranged in the first clamping groove, the O-shaped ring is arranged in the first sealing groove, the movable core is nested into the nut and is sleeved on the horizontal shaft together with the nut, so that the movable core can rotate flexibly relative to the horizontal shaft without displacement;

[0006] The second clamping groove and the third clamping groove are spaced apart on the vertical shaft, and the second sealing groove is further arranged between the second clamping groove and the third clamping groove, the C-shaped clamp spring is arranged in the second clamping groove and the third clamping groove, the O-shaped ring is arranged in the second sealing groove, the external thread joint is sleeved on the vertical shaft, and the third clamping groove is located below the bottom end of the external thread joint and abuts against the external thread joint, so that the external thread joint can rotate flexibly relative to the vertical shaft without displacement.

[0007] Preferably, the right-angle elbow body is formed by hot forging process. The problem of too large radius of the traditional elbow is solved.

[0008] Preferably, the thread of the external thread joint is any one of M1 / 2, M3 / 4 and M3 / 8. The external thread joint of the elbow can be freely replaced without damaging and disassembling the elbow, so that the conversion between different threads can be realized.

[0009] Preferably, the nut has an F1 / 2 or F3 / 4 thread. The nut on the elbow can be freely replaced with different threads without damaging or disassembling the elbow, enabling conversion between different threaded connections.

[0010] As a preferred option, the C-shaped circlip is a C-shaped steel wire circlip.

[0011] Compared with the prior art, the present invention has the following advantages after adopting the above solution:

[0012] This invention allows for 360° free movement and adjustment in two axes (X, Y). The external rotating part of the elbow eliminates the traditional reverse thread + glue fixing structure of the reverse core, employing a C-shaped retaining spring in conjunction with the right-angle elbow body. This ensures that reversing the direction of installation will not affect the structural loosening of the elbow, preventing leaks. The nut rotating part of the elbow eliminates the traditional fixed tightening method, using an added rotating movable core and a C-shaped retaining spring in conjunction with the elbow body, allowing the elbow body to move freely even after the nut is tightened. Furthermore, the traditional reverse thread connection of the reverse core in movable elbows requires sealant for fixation, posing a risk of rotational detachment. This invention eliminates this drawback with the retaining spring. The elimination of the traditional reverse thread + sealant structure also allows for free replacement of the connecting threads at both ends without damaging or disassembling the elbow, making it suitable for conversion between different threaded connections.
