[0014] Compared with the prior art, the beneficial effects of the utility model are:

[0015] (1) When installing the box body of the electric forklift, the L-shaped fixing plate is aligned with the slot and inserted into the slot. After the insertion, the threaded rod is driven to rotate by the driving component. Since the movement trajectory of the displacement plate is restricted, the displacement plate is synchronously driven to move in the vertical direction when the threaded rod rotates, and then the displacement plate is used to drive the locking column to move. After the locking column moves, it enters the interior of the locking groove, thereby completing the locking of the L-shaped fixing plate, thereby indirectly fixing the box body and the mounting plate together. Through the above structure, the box body can be installed and disassembled by one person or even one hand, which greatly reduces the difficulty of installing and disassembling the box body, saves labor to a certain extent, and reduces workload.

[0016] (2) When the electric control assembly for the electric forklift needs to clean the filter after long-term use, the bolts are unscrewed, and then the Z-shaped fixing plate is rotated to rotate around the mounting plate, and then the connecting plate is pulled to bring out the two filters. When installing, it is only necessary to reverse the above steps. With the above structure, when the filter is blocked or the filtering effect is poor, the filter can be disassembled and installed more conveniently, avoiding the problem of internal air flow being blocked due to filter blockage, thereby causing the temperature of the internal components to be too high.

When installing the box body 1, the L-shaped fixing plate 4 is aligned with the slot 3 and inserted. After insertion, the threaded rod 7 is driven to rotate by the driving assembly. Since the movement trajectory of the displacement plate 8 is restricted, the displacement plate 8 is synchronously driven to move in the vertical direction when the threaded rod 7 rotates, and then the displacement plate 8 is used to drive the locking column 9 to move. After the movement, the locking column 9 enters the locking groove 10, and then the L-shaped fixing plate 4 is locked, thereby indirectly fixing the box body 1 and the mounting plate 2 together. Through the above structure, when the box body 1 is installed and disassembled, only one person or even one hand is needed to complete it, which greatly reduces the difficulty of installing and disassembling the box body 1, saves labor to a certain extent, and reduces workload.

The right side surface of the Z-shaped fixing plate 23 contacts the left side surface of the connecting plate 20. The left side surface of the Z-shaped fixing plate 23 is provided with a bolt 24 for fixing. When disassembling, by pulling the control plate 14, the control plate 14 will synchronously drive the protrusion 15 to disengage from the groove 16 when being moved. At the same time, the control plate 14 will also drive the control rod 13 to move. After the control rod 13 moves, the reset plate 17 is synchronously used to compress the spring 18. Then, the control plate 14 is used to drive the control rod 13 to rotate, and then the control rod 13 is used to drive the worm 12 to rotate.

[0030] Working principle: When disassembling, by pulling the control plate 14, when the control plate 14 is moved, the protrusion 15 will be synchronously driven to disengage from the groove 16, and the control plate 14 will also drive the control rod 13 to move. After the control rod 13 moves, the reset plate 17 is synchronously used to compress the spring 18, and then the control plate 14 is used to drive the control rod 13 to rotate, and then the control rod 13 is used to drive the worm 12 to rotate. After the worm 12 rotates, the threaded rod 7 is synchronously driven to rotate by the worm wheel 11. When the filter 21 needs to be cleaned after a long period of use, the bolt 24 is twisted off, and then the Z-shaped fixing plate 23 is rotated to make it move around the fixing plate 22. Rotate, and then pull the connecting plate 20 to bring out the two filters 21. When installing, just reverse the above steps. When installing the box body 1, align the L-shaped fixing plate 4 with the slot 3 and insert it. After insertion, drive the threaded rod 7 to rotate through the driving assembly. Since the movement trajectory of the displacement plate 8 is restricted, the displacement plate 8 will be driven to move in the vertical direction when the threaded rod 7 rotates, and then the displacement plate 8 is used to drive the locking column 9 to move. After the locking column 9 moves, it enters the interior of the locking groove 10, thereby completing the locking of the L-shaped fixing plate 4, thereby indirectly fixing the box body 1 and the mounting plate 2 together.
