[0022] In this embodiment, a support shaft 2 is designed as a component to support the expansion plate 3 to be unfolded. The rotating rods on both sides of the support shaft 2 are arranged in the shaft tube 4. The shaft tube 4 is fixed on the outer surface of the transport vehicle body 1, so it supports the expansion plate 3 to rotate together with the support shaft 2. By designing the expansion plate 3, when the transport vehicle needs to pull more building materials, the expansion plate 3 can be unfolded to both sides to increase the cross-sectional area of the top, thereby increasing the capacity of the transport vehicle. By opening an expansion frame 12, the expansion plate 3 can have room for movement. By setting a connecting groove 13 inside the front baffle 5 and the rear baffle 6 as a storage space for the connecting plate 14, by setting the connecting plate 14 on both sides of the expansion plate 3, there are shielding on both sides of the expansion plate 3 when it is unfolded, so as to prevent the building materials from leaking from the expansion plate 3 during the transportation process.
[0023] Example 2
[0024] like Figure 3-Figure 4 As shown, a movable slot 7 is provided on the outer surface of the rear baffle 6, and a linkage rack 8 is provided on the outer surface of the movable slot 7. A driving gear 9 is meshedly connected to one side of the linkage rack 8, and a handle 10 is fixedly connected to the outer surface of the driving gear 9.

[0025] In this embodiment, by designing the movable notch 7, it is convenient to control the expansion of the expansion plate 3 from the rear side of the rear baffle 6. The movable notch 7 is connected to the connecting groove 13. By designing the connecting block 15 to be engaged with the movable notch 7, it is convenient to fix the connecting plate 14 and the linkage rack 8 as a whole through the connecting block 15. Since the expansion plate 3 has a fulcrum for rotation, the linkage rack 8 and the movable notch 7 are both arranged in an arc shape, making the movement process easier and unobstructed. By setting the driving gear 9, it is convenient to drive the linkage rack 8 and the connecting plate 14 by rotating the driving gear 9 to complete the rotation of the expansion plate 3. By designing the driven gear 11, the driving gear 9 can also drive the driven gear 11 to rotate. The structure at the driven gear 11 is the same as that at the driving gear 9, so it can be transmitted to both sides at the same time. The backs of the driving gear 9 and the driven gear 11 are connected to the outer surface of the rear baffle 6 through bearings, so that the gear transmission effect is better.
[0026] Working principle:
[0027] like Figure 1-Figure 4 As shown, when the extension part structure is used, by turning the handle 10, the driving gear 9 is rotated to drive the linkage rack 8 and the connecting plate 14. The driving gear 9 simultaneously drives the driven gear 11 to rotate. Both sides can rotate at the same time, and the extension plate 3 is then unfolded to both sides. The connecting plate 14 is slowly pulled out from the connecting groove 13, and finally the capacity of the transport vehicle is increased.
