[0003] When installing the existing drive shaft, it is usually necessary to place the flange at the outer end of the shaft tube corresponding to the external flange, and then use fixing bolts to fix the two groups of flanges. However, it is relatively difficult to align the flanges. And when installing the fixing bolts with the flanges staggered, the torque of the fixing bolts will be affected by the gravity of the shaft tube. Therefore, a device that can conveniently align the flanges is needed to facilitate the assembly of the drive shaft. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a drive shaft convenient for assembly, so as to solve the problem raised in the above background art that when installing the existing drive shaft, it is usually necessary to place the flange at the outer end of the shaft tube corresponding to the external flange, and then use fixing bolts to fix the two groups of flanges. However, it is relatively difficult to align the flanges. And when installing the fixing bolts with the flanges staggered, the torque of the fixing bolts will be affected by the gravity of the shaft tube.

[0019] 1. In the present utility model, by providing a movable component, one end of the sleeve is sleeved on the outer surface of the flange, and the sleeve is fixed by the fixing column. Then the other end of the sleeve is sleeved on the outer surface of the external flange. By moving the movable column inward, the movable column drives the fixing plate to move inward, and the fixing plate moves horizontally inward under the drive of the guide rod. When the two fixing plates move the same distance and fit with the outer side of the external flange, the positions of the two flanges can be made corresponding.

[0020] 2.

The turntable 26 is fixedly connected to the inner end of the movable column 23. The fixing hole 27 is opened on the outer surface of the flange 12;

[0036] The sleeve 21 is used to support the fixed column 22 and the movable column 23. The fixed column 22 is used to fix the sleeve 21. The movable column 23 is used to support the turntable 26. The turntable 26 is used to support the fixed plate 25. The guide rod 24 is used to guide the movement of the fixed plate 25. The fixing hole 27 is used to fix the fixed column 22;

[0037] The drive shaft assembly further includes a shaft tube 11;

[0040] The sleeve 21 is of a trapezoidal structure, and corresponding thread structures are provided on the inner surface of the fixing hole 27 and the lower outer surface of the fixed column 22;

[0041] When the fixed column 22 moves into the fixing hole 27 until the inner side of the upper end of the fixed column 22 contacts the outer surface of the sleeve 21, the sleeve 21 can be fixed at the outer surface position of the flange 12;

[0042] Corresponding thread structures are provided on the outer surface of the movable column 23 and the inner sides of both sides of the sleeve 21, and the turntable 26 is sleeved inside the outer side of the fixed plate 25;

[0043] The other end of the guide rod 24 is fixedly connected to both ends of the outer side of the fixed plate 25. There are scale lines on the outer surface of the guide rod 24. The fixed plate 25 is of an arc-shaped structure;

[0044] By rotating the movable column 23, the movable column 23 can move inward under the action of the thread structure, drive the turntable 26 to rotate and move inward, and the turntable 26 rotates inside the fixed plate 25 and drives the fixed plate 25 to move inward;

[0045] Working principle: When assembling the drive shaft assembly, sleeve 21 is sleeved on the outer surface of flange 12, and sleeve 21 is fixed on the outer surface of flange 12 by fixing post 22 in fixing hole 27. Then, sleeve 21 and the drive shaft assembly are moved so that the other end of sleeve 21 fits over the external flange 12. A rotational force is applied to movable post 23, causing movable post 23 to move inward through the threaded structure. Movable post 23 drives turntable 26 to rotate and move inward. Turntable 26 rotates inside fixed plate 25 and drives fixed plate 25 to move inward, causing fixed plate 25 to move inward along the direction of guide rod 24. According to the scale lines on the outer surface of guide rod 24, fixed plate 25 moves inward by the same distance. When the inner side surface of fixed plate 25 contacts the outer side surfaces of the two flanges 12, the two flanges 12 can be kept in a coaxial state, and then the two flanges 12 are fixed by fixing bolts to complete the installation.

[0046] Please refer to Figure 4 shown. Based on the above embodiment, this embodiment further includes:

[0047] A monitoring component, which includes movable disk 31, pressure sensor 32, telescopic spring 33, and baffle 34;

[0050] Corresponding threaded structures are provided on the inner surface of movable disk 31 and the outer surface of shaft tube 11, and movable disk 31 is located on one side of flange 12;

[0051] Movable disk 31 can move and be fixed on the outer surface of shaft tube 11 through the threaded structure;

[0052] Working principle: When it is necessary to monitor the state of the transmission shaft assembly, a rotational force is applied to the movable disk 31, causing the movable disk 31 to rotate and move along the threaded structure on the outer surface of the shaft tube 11. The movement of the movable disk 31 drives the baffle 34 to move. When the outer side of the baffle 34 comes into contact with the outer side of the fixing bolt, the force applied to the movable disk 31 is stopped, and the movable disk 31 is fixed on the outer surface of the shaft tube 11 by the threaded structure. At this time, when the fixing bolt becomes loose, the fixing bolt shakes under the drive of the flange 12, and the fixing bolt applies an inward thrust to the baffle 34. The baffle 34 drives the compression of the telescopic spring 33, and the pressure sensor 32 measures the elastic force of the telescopic spring 33. The state of the fixing bolt can be monitored through the pressure measured by the pressure sensor 32.
