[0023] Reference Figure 1-Figure 5 A drive wheel that is easy to maintain, comprising a shaft body 1 and a drive wheel 2 sleeved on the shaft body 1, a mounting cavity is provided in the shaft body 1, a mounting rod 3 is fixedly installed horizontally on the wall of the mounting cavity, a plurality of first spring rods 4 are fixedly installed on the surface of the mounting rod 3 in a circumferential shape, a plurality of through openings 5 ​​that are all connected to the mounting cavity are provided in a circumferential shape on the surface of the shaft body 1, a locking block 6 is slidably installed in the through opening 5, and one end of the plurality of first spring rods 4 is fixedly connected to the surface of the plurality of locking blocks 6 respectively;

[0024] An inclined plate 7 is fixedly installed on the surface of the locking block 6, a mounting groove is horizontally opened at one end of the shaft body 1, a through hole is opened on the wall of the mounting groove, a plug rod 8 is slidably inserted in the through hole, a mounting block 9 is fixedly installed on one end of the plug rod 8 located in the mounting cavity, a plurality of trapezoidal pressure plates 10 are fixedly installed on the surface of the mounting block 9 in a circumferential shape, the inclined surfaces of the plurality of pressure plates 10 are in sliding contact with the inclined surfaces of the plurality of inclined plates 7 respectively, a push plate 11 is fixedly installed on one end of the plug rod 8 located in the mounting groove, the plug rod 8 is connected to the mounting groove through a telescopic component, the telescopic component includes a telescopic spring 13 sleeved on the plug rod 8, and the two ends of the telescopic spring 13 are respectively fixedly connected to the surface of the push plate 11 and the wall of the mounting groove, and a plurality of locking grooves 12 for inserting the locking block 6 are opened in a circumferential shape on the inner wall of the driving wheel 2;

[0025] When the driving wheel 2 needs to be installed, first push the push plate 11 to move toward the direction close to the installation groove, so that the inclined surfaces of the multiple pressure plates 10 are respectively in sliding contact with the inclined surfaces of the multiple inclined plates 7. Under the action of the inclined surface pressure, the multiple first spring rods 4 will shrink, and the multiple locking blocks 6 will move in the multiple openings 5 ​​respectively, until the multiple locking blocks 6 are respectively moved back into the multiple openings 5, and then the driving wheel 2 is sleeved on the shaft body 1 until the driving wheel 2 moves to a suitable position. At this time, the driving wheel 2 is rotated to control the multiple locking grooves 12 to correspond to the positions of the multiple locking blocks 6 respectively, and then the push plate 11 is released. The push plate 11, the insertion rod 8, the installation block 9 and the multiple pressure plates 10 will quickly move and reset under the elastic potential energy of the telescopic spring 13, and the pressure force of the multiple pressure plates 10 on the multiple inclined plates 7 disappears. The multiple locking blocks 6 will quickly move and reset under the elastic potential energy of the first spring rods 4, and are respectively inserted into the multiple locking grooves 12, thereby completing the locking of the driving wheel 2 and the shaft body 1;

[0026] When the driving wheel 2 needs to be removed, it is only necessary to push the push plate 11 toward the direction close to the installation groove, so that the multiple locking blocks 6 move in the multiple openings 5 ​​respectively, until the multiple locking blocks 6 move back into the multiple openings 5 ​​respectively, and the multiple locking blocks 6 will also be moved out of the multiple locking grooves 12 respectively, to release the lock of the driving wheel 2, and then the driving wheel 2 can be removed from the shaft body 1, avoiding the cumbersome steps of using screw and nut fixings, improving the efficiency of disassembling and assembling the driving wheel 2, and improving the efficiency of maintaining the driving wheel 2.

[0027] A limiting component is provided on the surface of the push plate 11, and the limiting component is used to limit the movement of the push plate 11. The limiting component includes two second spring rods 14. A rectangular groove is symmetrically provided on the surface of the push plate 11. The two second spring rods 14 are respectively and horizontally fixedly installed in the two rectangular grooves. The walls of the rectangular grooves are provided with sockets. A locking port 15 for inserting the end of the second spring rod 14 is symmetrically provided on the surface of one end of the shaft body 1. A pull plate 16 is fixedly sleeved on the second spring rod 14, and the surface of the pull plate 16 is provided with anti-slip grooves.

[0028] When the push plate 11 does not move, the ends of the two second spring rods 14 will pass through the two insertion holes and the two locking holes 15 respectively, thereby completing the locking of the push plate 11, and then limiting the movement of the mounting block 9 and the pressure plate 10, preventing the insertion rod 8 from being affected by the vibration force and moving with the mounting block 9 and the pressure plate 10 during the rotation of the shaft body 1 with the driving wheel 2, thereby causing the locking block 6 to release the locking of the driving wheel 2, thereby improving the stability of locking the driving wheel 2;

[0029] When the push plate 11 needs to be controlled to move, the two pull plates 16 are pulled closer to each other to control the two second spring rods 14 to shrink together, so that the ends of the two second spring rods 14 are respectively moved out of the two locking openings 15, thereby releasing the lock on the push plate 11.

[0030] A magnetic block is fixedly installed on the wall of the locking groove 12. The locking block 6 is made of magnetic material. When the locking block 6 enters the locking groove 12, it will be magnetically attracted, thereby reducing the impact of the vibration force generated during the rotation of the shaft body 1 with the driving wheel 2 on the locking block 6.

[0031] In the present invention, when the driving wheel 2 needs to be installed, the push plate 11 is first pushed to move toward the direction close to the installation groove, so that the inclined surfaces of the multiple pressure plates 10 are respectively in sliding contact with the inclined surfaces of the multiple inclined plates 7. Under the action of the inclined surface pressure, the multiple first spring rods 4 will shrink, and the multiple locking blocks 6 will respectively move in the multiple through openings 5 ​​until the multiple locking blocks 6 are respectively moved back into the multiple through openings 5. At this time, the driving wheel 2 is sleeved on the shaft body 1 until the driving wheel 2 moves to a suitable position. At this time, the driving wheel 2 is rotated to control the multiple locking grooves 12 to correspond to the positions of the multiple locking blocks 6 respectively, and then the push plate 11 is released. The push plate 11, the insertion rod 8, the installation block 9 and the multiple pressure plates 10 will quickly move and reset under the elastic potential energy of the telescopic component, and the multiple pressure plates When the pressing force applied by the plurality of inclined plates 7 by 10 disappears, the plurality of locking blocks 6 will quickly move and reset under the elastic potential energy of the first spring rod 4, and be respectively inserted into the plurality of locking grooves 12, thereby completing the locking of the drive wheel 2 and the shaft body 1. When the drive wheel 2 needs to be removed, it is only necessary to push the push plate 11 toward the direction close to the installation groove to make the plurality of locking blocks 6 move in the plurality of through openings 5 ​​respectively, until the plurality of locking blocks 6 are respectively moved back into the plurality of through openings 5, the plurality of locking blocks 6 will also be respectively moved out from the plurality of locking grooves 12, thereby releasing the lock of the drive wheel 2, and then the drive wheel 2 can be removed from the shaft body 1, thereby avoiding the cumbersome steps of using screw and nut fixings, improving the efficiency of disassembling and assembling the drive wheel 2, and improving the efficiency of maintaining the drive wheel 2.

[0032] In the present invention, unless otherwise clearly specified or limited, the terms "installed", "connected", "connected", "fixed" and the like should be understood in a broad sense.
