Detailed Description

The technical solution of the present invention is further explained by the following specific embodiments with reference to the accompanying drawings.

Example (b): referring to fig. 1, an angle adjusting device for a rotating pipe fitting comprises a positioning pipe 1, a positioning pin 2, a gear seat 3, a rotating pipe 4, a positioning seat 5, a spring 6, a shaft pin 7, an end sleeve 8, an adjusting seat 9 and a spacer 10; the device is characterized in that a gear seat 3 is fixedly connected on a positioning pipe 1 through a positioning pin 2; the positioning seat 5 is sleeved on the rotating tube 4 and is fixedly connected with the rotating tube 4 through a shaft pin 7; an end sleeve 8 is arranged at the port of the rotating tube 4, and a shaft pin 7 penetrates through the end sleeve 8, the rotating tube 4 and the spacing gasket 10 to be hinged with the positioning tube 1; the spring 6 and the adjusting seat 9 are sleeved on the rotating pipe 4.

Referring to fig. 2, the gear seat 3 go up connecting groove 31, fixed orifices 32, first draw-in groove 33, second draw-in groove 34, third draw-in groove 35, connecting groove 31 laminate mutually with the outer wall of registration arm 1, locating pin 2 passes fixed orifices 32 and will keep off gear seat 3 rigid coupling on registration arm 1, first draw-in groove 33, second draw-in groove 34, third draw-in groove 35 arrange in proper order and set up in connecting groove 31 below. The first card slot 33, the second card slot 34 and the third card slot 35 are arranged in a C shape.

Referring to fig. 3, the spring 6 is right-handed, and the inner diameter of the spring 6 is larger than that of the rotating pipe 4, so that the spring 6 can be sleeved on the rotating pipe 4.

Referring to fig. 4, the adjusting seat 9 is provided with a covering groove 91, a sliding groove 92 and an adjusting column 93; cover groove 91 and sliding tray 92 coaxial setting, cover the internal diameter of groove 91 and be greater than the external diameter of positioning seat 5 and spring 6, the internal diameter of sliding tray 92 is greater than the external diameter of rotating tube 4, is less than the external diameter of spring 6, adjusts the post 93 setting in the sliding tray 92 outside.
