[0024] Such as Figures 1 to 4As shown in the figure, a multifunctional adjustable-angle gear shaft according to an embodiment of the present invention includes a fixed shaft 1. A gear inner ring 11 is fixedly connected to the outer side wall of the fixed shaft 1. A rotating shaft 12 is fixedly connected to the middle of the outer side wall of the gear inner ring 11. A plurality of groups of rotating shafts 12 are arranged on the outer side wall of the gear inner ring 11 and are evenly distributed on the outer side wall of the gear inner ring 11. A gear tooth 13 is rotatably connected to the outer side wall of the rotating shaft 12. A swing column 14 is fixedly connected to the end of the gear tooth 13. The swing column 14 is provided at both ends of the gear tooth 13. An adjusting assembly is provided on the outer side wall of the fixed shaft 1 close to the gear tooth 13. A fixing assembly is provided in the middle of the gear tooth 13 close to the swing column 14. During operation, when the angle needs to be adjusted, it is adjusted through the adjusting assembly. The adjusting assembly simultaneously pushes the swing column 14 at the end of the gear tooth 13, so that the gear tooth 13 rotates along the rotating shaft 12, and the angle between the gear tooth 13 and the fixed shaft 1 changes. After the angle of the gear tooth 13 is adjusted to a specified value, the gear tooth 13 is locked and fixed through the fixing assembly. The gear tooth 13 can be adjusted in two-way angles along the rotating shaft 12. Through the settings of the fixed shaft 1, the gear inner ring 11, the rotating shaft 12, the gear tooth 13 and the swing column 14, an adjustable-angle gear shaft is formed, realizing the adjustment of the angle between the gear shaft and the gear tooth 13, which can be adjusted at multiple angles, solving the problem of low adaptability of the gear shaft, improving the convenience of angle adjustment of the gear shaft, and increasing the adaptability of the gear shaft under different working conditions.

[0025] As Figure 1 and Figure 3 shown, the adjusting assembly includes a turntable 2, a connecting column 21 and a rotating piece 22. The turntable 2 is rotatably connected to the outer side wall of the fixed shaft 1 close to the gear tooth 13. A pair of turntables 2 are arranged on the outer side wall of the fixed shaft 1 and are symmetrically arranged. The connecting column 21 is fixedly connected to the end of the turntable 2 close to the gear tooth 13. A plurality of groups of connecting columns 21 are arranged at the end of the turntable 2 close to the gear tooth 13. The rotating piece 22 is fixedly connected to the end of a group of connecting columns 21 away from the turntable 2. The rotating piece 22 is sleeved on the outer side wall of the swing column 14. During operation, when the angle of the gear tooth 13 needs to be adjusted, rotate a pair of turntables 2 to rotate in opposite directions. The turntable 2 drives the connecting column 21 and the rotating piece 22 to rotate. The rotating piece 22 pushes the swing column 14, so that the gear tooth 13 rotates around the rotating shaft 12 as the center, achieving the function of simultaneously adjusting the angles of multiple groups of gear teeth 13. Through the settings of the turntable 2, the connecting column 21 and the rotating piece 22, an adjusting structure is formed, realizing the function of simultaneously adjusting the angles of the gear teeth 13, solving the cumbersome problem when adjusting the angles of multiple groups of gear teeth 13, increasing the convenience when adjusting the angles of multiple groups of gear teeth 13, and increasing the consistency when adjusting multiple groups of gear teeth 13.

[0026] As Figure 2As shown, the fixing component includes a first fastening screw 3 and a clamping plate 31. The first fastening screw 3 is rotatably connected to the middle of the tooth 13. The first fastening screw 3 is slidably connected to the outer side wall of the inner ring 11 of the gear. The clamping plate 31 is threadedly connected to the outer side wall of the first fastening screw 3 near the inner ring 11 of the gear. During operation, after the angle of the tooth 13 is adjusted to a suitable position, the first fastening screw 3 is screwed to drive the clamping plate 31 to approach the tooth 13 and contact the inner side wall of the inner ring 11 of the gear, fixing the tooth 13 to the outer side wall of the inner ring 11 of the gear. Through the arrangement of the first fastening screw 3 and the clamping plate 31 in this step, a fixing structure is formed, realizing the function of fixing the tooth 13 to the outer side wall of the inner ring 11 of the gear, solving the problem that the tooth 13 still rotates after adjustment, improving the stability of the tooth 13 on the outer side wall of the inner ring 11 of the gear, and increasing the situation where the angle of the tooth 13 remains stable during the operation of the device.

[0027] As Figure 4 shown, a sealing ring 4 is fixedly connected to the end of the inner ring 11 of the gear near the clamping plate 31. The sealing ring 4 is provided at both ends of the inner ring 11 of the gear. During operation, the sealing ring 4 is fixed to the end of the inner ring 11 of the gear to seal the end of the inner ring 11 of the gear, reducing the situation of lubricating grease entering the inside of the inner ring 11 of the gear. Through the arrangement of the sealing ring 4 in this step, the end of the inner ring 11 of the gear is sealed, increasing the sealing performance of the end of the inner ring 11 of the gear, and solving the problem that lubricating grease enters the inside of the inner ring 11 of the gear, causing the clamping plate 31 to slide and affecting the fixing of the tooth 13.

[0028] As Figure 3 shown, a second fastening screw 5 is threadedly connected to the outer side wall of the turntable 2. A pair of second fastening screws 5 are provided on the outer side wall of the turntable 2 and are symmetrically arranged. During operation, after the angle of the tooth 13 is adjusted, the second fastening screw 5 is tightened. The end of the second fastening screw 5 close to the fixed shaft 1 contacts the second fastening screw 5, fixing the turntable 2 to the top of the inner ring 11 of the gear. Through the arrangement of the second fastening screw 5 in this step, the adjusted turntable 2 is fixed to the outer side wall of the fixed shaft 1, reducing the situation of the turntable 2 slipping when the fixed shaft 1 rotates, thereby affecting the angle of the tooth 13 and improving the stability during the operation of the device.

[0029] As Figure 3 shown, anti-slip strips 6 are fixedly connected to the outer side wall of the turntable 2. Multiple groups of anti-slip strips 6 are provided on the outer side wall of the turntable 2. During operation, when the turntable 2 is rotated, the anti-slip strips 6 increase the roughness of the outer side wall of the turntable 2. Through the arrangement of the anti-slip strips 6 in this step, the roughness of the outer side wall of the turntable 2 is increased, reducing the situation of the turntable 2 slipping when it is rotated.

[0030] As Figure 1As shown, a storage groove 7 is formed on the side wall of the tooth 13. Multiple groups of storage grooves 7 are provided on the side wall of the tooth 13. During operation, a storage groove 7 is formed in the middle of the tooth 13, and the grease remains in the storage groove 7. Through the setting of the storage groove 7 in this step, the grease remains in the storage groove 7, reducing the occurrence of dry friction of the tooth 13 and reducing the occurrence of abnormal wear of the tooth 13.

[0031] During operation, when the angle needs to be adjusted, it is adjusted through the adjusting component. The adjusting component simultaneously pushes the swing column 14 at the end of the tooth 13, causing the tooth 13 to rotate along the rotating shaft 12, changing the angle between the tooth 13 and the fixed shaft 1. After the angle of the tooth 13 is adjusted to the specified value, the tooth 13 is locked and fixed through the fixing component. The tooth 13 can be adjusted in two-way angles along the rotating shaft 12. When the angle of the tooth 13 needs to be adjusted, rotate a pair of turntables 2 in opposite directions. The turntables 2 drive the connecting column 21 and the rotating piece 22 to rotate. The rotating piece 22 pushes the swing column 14, causing the tooth 13 to rotate around the rotating shaft 12, achieving the function of adjusting the angles of multiple groups of teeth 13 simultaneously. After the angle of the tooth 13 is adjusted to a suitable position, turn the first fastening screw 3 to drive the clamping plate 31 to approach the tooth 13 and contact the inner side wall of the inner ring 11 of the gear, fixing the tooth 13 on the outer side wall of the inner ring 11 of the gear. The sealing ring 4 is fixed at the end of the inner ring 11 of the gear to seal the end of the inner ring 11 of the gear, reducing the situation of grease entering the inside of the inner ring 11 of the gear. After the angle of the tooth 13 is adjusted, tighten the second fastening screw 5. The end of the second fastening screw 5 close to the fixed shaft 1 contacts the second fastening screw 5, fixing the turntable 2 on the top of the inner ring 11 of the gear. When the turntable 2 is rotated, the anti-slip strip 6 increases the roughness of the outer side wall of the turntable 2. A storage groove 7 is formed in the middle of the tooth 13, and the grease remains in the storage groove 7.
