[0023] The cargo box further includes a tarpaulin 3 that can cover the upper end of the box body 1. The arrangement of the tarpaulin 3 can effectively prevent the spillage of construction waste during the operation of the vehicle and protect the road environment. The tarpaulin 3 is flush with the upper end of the box body 1, which can effectively control the volume and weight of the construction waste carried by the vehicle, thereby avoiding overloading.

[0024] Furthermore, the tarpaulin 3 is telescopically arranged at the upper end of the box body 1. A chain is provided at the upper end of the box body 1. One end of the tarpaulin 3 is connected to one end of the box body 1, and the other end of the tarpaulin 3 is operably fixed to the upper end of the loading and unloading baffle 2; in a preferred embodiment, the other end of the tarpaulin 3 is connected to the chain, and the rotation of the chain drives the tarpaulin 3 to move along the upper end of the box body 1, thereby realizing the telescoping of the tarpaulin 3 and the opening and closing of the upper end of the accommodating space.

[0025] See Figures 2 - 3 As shown, the cargo box of the vehicle further includes a plurality of skeletons 4. The plurality of skeletons 4 are fixedly connected to the tarpaulin 3 in sequence along the telescoping direction of the tarpaulin 3. The skeletons 4 and the box body 1 are slidably connected; in a preferred embodiment, a skeleton 4 is provided at the other end of the tarpaulin 3. This skeleton 4 is connected to the chain to drive the telescoping of the tarpaulin 3. The remaining skeletons 4 are distributed along the length direction of the tarpaulin 3. During the contraction process, the skeleton 4 located at the other end of the tarpaulin 3 will sequentially contact and push each skeleton 4 to move to complete the contraction of the tarpaulin 3; during the extension process, the skeleton 4 located at the other end of the tarpaulin 3 will pull other skeletons 4 to move sequentially through the tarpaulin 3 to complete the overall extension.

[0026] Furthermore, the part of the skeleton 4 spanning the upper end of the box body 1 forms a top covering plane, and the top covering plane fits with the upper end of the box body 1. The tarpaulin 3 is sequentially connected to the skeletons 4. When unfolded, the tarpaulin 3 is flattened and is generally flush with the top covering plane. At this time, the tarpaulin 3 and the upper end of the box body 1 are in contact, which can effectively control the volume and weight of the construction waste carried by the vehicle, thereby avoiding overloading.

[0027] Furthermore, slide rails 11 are provided on both sides of the box body 1, and slider blocks 41 are provided at both ends of the skeleton 4. The skeleton 4 spans both sides of the upper end of the box body 1, and the slider blocks 41 cooperate with the slide rails 11.

[0029] In a preferred embodiment, the rotary locking mechanism 5 can be fixed to the loading and unloading baffle 2. Specifically, the loading and unloading baffle 2 is of a hook type. A fixing hole is provided on the loading and unloading baffle 2, and a positioning hole matching the fixing hole is provided on the loading and unloading baffle 2. In the extended state of the tarpaulin 3, the fixing hole and the positioning hole are connected by bolts to fix the rotary locking mechanism 5 and the loading and unloading baffle 2.

[0030] In another preferred embodiment, a cover pressing plate 21 is connected to the upper end of the loading and unloading baffle 2. The cover pressing plate 21 is rotatably connected to the upper end of the loading and unloading baffle 2. The cover pressing plate 21 presses on the other end of the tarpaulin 3 to form a fixation. A rotary locking mechanism 5 is provided on the other end of the tarpaulin 3. A locking port 511 is provided on the rotary locking mechanism 5. In the extended state of the tarpaulin 3, after the cover pressing plate 21 passes through the locking port 511, it presses on the rotary locking mechanism 5 to form a fixation.

[0031] Further, the rotary locking mechanism 5 includes a locking end 51, a rotating end 52 and a balancing end 53. The rotating end 52 connects the locking end 51 and the balancing end 53. The rotating end 52 is rotatably connected to a framework 4 on the other end of the tarpaulin 3. The locking port 511 is provided on the locking end 51.

[0032] A limiting spring is provided inside the rotary locking mechanism 5. The limiting spring has a first state in the normal state and a second state in which it is compressed.
