[0021] The following will be combined with the drawings of the specification of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] Reference Figure 1-3 , an embodiment of the utility model: a direction-adjustable rotary joint comprises a connecting pipe 1, a pressure balancing assembly is arranged on the top of the connecting pipe 1, the pressure balancing assembly is used to prevent leakage under high pressure, a fixed pipe 4 is fixedly connected to the left side of the connecting pipe 1, a fixed ring 5 is fixedly connected to the left side of the fixed pipe 4, a connecting ring 21 is fixedly connected to the left side of the fixing ring 5, a sun gear 23 is fixedly connected to the left side of the connecting ring 21, a second slide groove 27 is opened on the right side of the surface of the connecting ring 21, the second slide groove 27 is rotatably connected to the gear ring 19, a first slide groove 22 is opened on the left side of the surface of the connecting ring 21, a rotating ring 24 is arranged in the first slide groove 22, the rotating ring 24 is rotatably connected to the connecting ring 21, a plurality of planetary gears 25 are rotatably connected to the left side of the rotating ring 24, an adjusting ring 26 is rotatably connected between the left sides of the plurality of planetary gears 25, a scale ring 7 is fixedly connected to the left side of the adjusting ring 26, and a rotating pipe 6 is fixedly connected to the left side of the scale ring 7.

[0023] The sun gear 23 is meshed with the planetary gears 25, and the gear ring 19 can rotate on the second slide groove 27. The inner wall of the gear ring 19 is meshed with the planetary gears 25, and the gear ring 19 can drive the planetary gears 25 to rotate. While rotating, the planetary gears 25 will also revolve around the sun gear 23. Because the radius and the number of teeth of the gear ring 19 are larger than the radius and the number of teeth of the sun gear 23, which are larger than the radius and the number of teeth of the planetary gears 25, the speed of the planetary gear 25 revolves slower than the gear ring 19. The revolution of the planetary gear 25 will drive the rotating ring 24 and the adjusting ring 26 to rotate, thereby achieving the effect of fine-tuning the angle.

[0024] Reference Figure 2 The pressure balancing assembly includes a one-way valve 15, which is fixedly connected to the connecting pipe 1. The top of the one-way valve 15 is fixedly connected to the air pressure tank 3, the top of the inner wall of the air pressure tank 3 is fixedly connected to the telescopic rod 13, and the bottom of the telescopic rod 13 is fixedly connected to the partition 14.

[0025] The one-way valve 15 prevents gas from flowing back from the air pressure tank 3 into the connecting pipe 1. The telescopic rod 13 is used to drive the partition 14 to slide freely in the air pressure tank 3. The partition 14 responds to pressure changes by moving up and down. A good seal is maintained between the partition 14 and the inner wall of the air pressure tank 3 to prevent pressure leakage.

[0026] Reference Figure 2 A spring 18 is fixedly connected to the left side of the inner wall of the connecting tube 1, and a rotating tube 2 is fixedly connected to the right side of the spring 18.

[0027] The spring 18 is used to buffer the back and forth shaking of the rotating tube 2 during rotation.

[0028] Reference Figure 2 Two limiting rings 16 are fixedly connected to the surface of the rotating tube 2 , and a plurality of balls 17 are arranged inside the two limiting rings 16 .

[0029] The limiting ring 16 fits tightly with the connecting tube 1 to prevent leakage of the internal liquid during transmission, and the ball 17 enables the rotating tube 2 to rotate in the connecting tube 1.

[0030] Reference Figure 2 A pointer 12 is fixedly connected to the top of the fixed ring 5, and scale lines 8 are arranged on the surface of the scale ring 7.

[0031] The left end of the pointer 12 points to the scale line 8, which is used by the user to observe the degree change of the current adjustment.

[0032] Reference Figure 1 The left side of the rotating tube 6 is fixedly connected with an adjusting tube 20, and the inner diameter of the adjusting tube 20 is rotatably connected with a ball 11.

[0033] The sphere 11 is provided with holes for the transmission objects to pass through.

[0034] Reference Figure 2 A connecting rod 9 is fixedly connected to the top of the ball 11.

[0035] The connecting rod 9 is used to drive the ball 11 to rotate.

[0036] Reference Figure 2 A knob 10 is fixedly connected to the top of the connecting rod 9.

[0037] The knob 10 is used to drive the connecting rod 9 to rotate.

[0038] Working principle: the sun gear 23 is meshed with the planetary gear 25, the gear ring 19 can rotate on the second slide groove 27, the inner wall of the gear ring 19 is meshed with the planetary gear 25, when the gear ring 19 is rotated, the gear ring 19 can drive the planetary gear 25 to rotate, and the planetary gear 25 will also revolve around the sun gear 23 while rotating. Because the radius and the number of teeth of the gear ring 19 are larger than the radius and the number of teeth of the sun gear 23, which are larger than the radius and the number of teeth of the planetary gear 25, the speed of the planetary gear 25 revolves slower than the gear ring 19, and the revolution of the planetary gear 25 will drive the rotating ring 24 and the adjusting ring 26 to rotate, thereby achieving the effect of fine-tuning the angle, and the left end of the pointer 12 points to the scale line 8, which is used for the user to observe the current adjustment degree change. When in use, the high pressure generated by the rotation will enter the air pressure tank 3 from the one-way valve 15, and the one-way valve 15 prevents the gas from flowing back from the air pressure tank 3 to the connecting pipe 1. The telescopic rod 13 is used to drive the partition 14 to slide freely in the air pressure tank 3. The partition 14 responds to the pressure change by moving up and down. A good seal is maintained between the partition 14 and the inner wall of the air pressure tank 3 to prevent pressure leakage. The real-time change between the internal telescopic rod 13 and the partition 14 realizes the effect of balancing the high air pressure. The spring 18 is used to buffer the back and forth shaking of the rotating tube 2 during rotation. The limit ring 16 fits tightly with the connecting pipe 1 to prevent leakage during internal liquid transmission. The ball 17 realizes the rotation of the rotating tube 2 in the connecting pipe 1. The knob 10 is used to drive the connecting rod 9 to rotate. The connecting rod 9 is used to drive the ball 11 to rotate. A hole is opened in the ball 11 for transmitting objects to pass through it, so that the material throughput can be adjusted when the angle of the ball 11 is adjusted.
