Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Reference Figure 1 and Figure 3 This utility model provides an embodiment of a PLC modular training device, including a base 1 for supporting the top structure and equipment. A top frame 2 is fixedly connected to the top of the base 1 for supporting the internal structure and equipment. Fixing plates 3 are fixedly connected to the left and right sides of the base 1 to fix the connected devices to the sides of the base 1. A drive assembly is fixedly connected to one side of the fixing plate 3 to provide power for the storage of the universal wheels 15 of the device. The drive assembly includes a fixed shaft 4, a cylinder 5, and a sleeve 6. The outer side of the fixed shaft 4 is fixedly connected to the outer side of the fixing plate 3 to provide a base point for the rotation of the cylinder 5. One end of the cylinder 5 is rotatably connected to the outside of the fixed shaft 4 to keep the cylinder 5 stable during device operation. The outside of the sleeve 6 is fixedly connected to the drive end of the cylinder 5. A second fixed shaft 7 is fixedly connected to the outer side of the fixing plate 3. The external structure provides a base point for the rotation of the follower rod 8. The follower rod 8 is rotatably connected to the outside of the fixed shaft 7. The sleeve 6 is rotatably connected to the outside of the follower rod 8, so that the movement of the sleeve 6 can interfere with the movement of the follower rod 8. The fixed shaft 9 is fixedly connected to the outside of the fixed plate 3. One end of the follower rod 10 is rotatably connected to the outside of the fixed shaft 9, which can drive the power of the follower rod 8 to the follower rod 13. The other end of the follower rod 10 is fixedly connected to the connecting shaft 11. The connecting shaft 12 is rotatably connected to the inside of the follower rod 8. The follower rod 13 is rotatably connected to the outside of the connecting shaft 11. The outside of the connecting shaft 12 is rotatably connected to the inside of the follower rod 13. The fixed rod 14 is fixedly connected to the bottom of the fixed plate 3. The universal wheel 15 is fixedly connected to the bottom of the follower rod 13, which can provide the ability of the device to move.

[0022] like Figure 1 and Figure 2 As shown: A shelf 16 is fixedly connected to the front exterior of the top frame 2, and a hanging board 17 is fixedly connected to the front exterior of the top frame 2, which can hang different objects on the device. Two lamp tubes 18 are fixedly connected to the top of the top frame 2 to provide light for the staff. An anti-static board 19 is fixedly connected to the top of the base 1 to prevent static electricity from damaging the device. A control panel 20 is fixedly connected to the top of the anti-static board 19. A connecting cable 21 is fixedly connected to the outer side of the control panel 20 for transmitting signals. A toolbox 22 is fixedly connected to the top of the anti-static board 19. A training board 23 is fixedly connected to the top of the anti-static board 19. Multiple fixed brackets 24 are fixedly connected inside the base 1. Two casters 25 are fixedly connected to the front bottom of the base 1 to facilitate the movement of the device.

[0023] Compared with some existing technologies, the above content enables the device to move and be easily fixed during use by driving multiple follower rods through cylinder 5, thus solving the problem of poor mobility of some devices.

[0024] Working principle: First, the cylinder 5 is activated, causing the drive end to move the sleeve 6. Because one end of the cylinder 5 is rotatably connected to the outside of the fixed shaft 4, the cylinder 5 can drive the sleeve 6 to move the follower rod 8. Therefore, one end of the follower rod 8 rotates around the fixed shaft 7, and the other end of the follower rod 8 is rotatably connected to the connecting shaft 12. Since the other end of the follower rod 13 rotates on the connecting shaft 12, and the internal part of the follower rod 13 is rotatably connected to the connecting shaft 11, the follower rod 13 outside the connecting shaft 11... The device can rotate around the fixed shaft 9 as a base point, thereby extending the caster wheel 15 from the bottom of the device. The extension of the caster wheel 15 prevents the fixed rod 14 from contacting the plane, allowing the device to move. When it moves to the appropriate position, the cylinder 5 is activated to retract the caster wheel 15 at the bottom of the device, fixing the device on the plane. A shelf 16 is fixed on the top of the device for storing objects. The hanging shelf 17 can hang multiple tools. The operator can transmit signals to the PLC host on the top of the training board 23 through the control panel 20.
