[0042] Specific structure such as Figures 1 to 9 shown.

[0043] The present embodiment provides a cab of a sanitation vehicle, comprising a splicing device, a front windshield 1, a front wall skin 2, a rear wall skin 3, a top wall skin 4, and side wall skins 5 on the left and right sides, wherein the front wall skin 2, the rear wall skin 3, the top wall skin 4, and the side wall skins 5 are connected to each other to form a driving space, and the front windshield 1 is located between the front end of the top wall skin 4 and the front wall skin 2, the front and rear ends of the top wall skin 4 have arc-shaped portions 28, and the side wall skins 5 are arranged on the inner side of the top wall skin 4 and are spliced ​​by the splicing device. The splicing device comprises a first positioning block 6, a first guide plate 7, a second guide plate 8, a positioning plate 9, a sliding plate 10, a screw 11, a handle 12, an L-shaped plate 13 and a telescoping device 14; the first positioning block 6 has a first side and a second side opposite to each other, the first guide plate 7 and the second guide plate 8 are relatively arranged on the first side of the first positioning block 6, and the first guide plate 7 is connected to the first side of the first positioning block 6, and the first guide plate 7 and the second guide plate 8 are opposite to each other. The side is provided with a guide structure 29, and the first positioning block 6 has a first side and a second side. The second side of the positioning block 6 is used to be fixed to the inner side wall of the side wall skin 5; the positioning plate 9 and the sliding plate 10 are relatively arranged between the first guide plate 7 and the second guide plate 8, and the positioning plate 9 is fixedly connected to the first guide plate 7 and the second guide plate 8, the sliding plate 10 is slidably connected to the guide structure 29, the screw 11 is passed through the positioning plate 9 and the sliding plate 10, and is threadedly matched with the sliding plate 10, the handle 12 is transmission-connected to one end of the screw 11, and the handle 12 drives the screw 11 to rotate by rotating so that the sliding plate 10 moves toward or away from the positioning plate 9 along the guide structure 29; the L-shaped plate 13 has a first side and a second side perpendicular to each other, the first side is passed between the positioning plate 9 and the sliding plate 10, and the end is used to connect to the inner side wall of the arc portion 28, there is a gap between the second side and the first positioning block 6, the retractor 14 is arranged in the gap, and one end of the retractor 14 is connected to the second side, and the other end is connected to the first positioning block 6.

[0044] In this embodiment, the front enclosure skin 2, the rear enclosure skin 3, the top enclosure skin 4 and the side enclosure skin 5 are separately manufactured and welded to form a driving space, without the need for mold stamping and forming, thus saving costs and improving market competitiveness. At the same time, before the top enclosure skin 4 and the side enclosure skin 5 are welded, in order to ensure the verticality between the two, they are first spliced ​​by a splicing device and then welded, which effectively ensures the verticality between the top enclosure skin 4 and the side enclosure skin 5. Specifically, when the splicing device is in use, the second side of the first positioning block 6 is welded to the inner wall of the side enclosure skin 5, the end of the first side of the L-shaped plate 13 passes between the positioning plate 9 and the sliding plate 10 and is welded to the inner wall of the arc-shaped portion 28, the handle 12 is turned to drive the screw 11 to rotate so that the sliding plate 10 moves along the guide structure 29 toward the positioning plate 9 to clamp the first side of the L-shaped plate 13 to ensure the stability of the L-shaped plate 13, the telescoping device 14 is installed between the second side and the first positioning block 6, and the two ends are connected to the second side and the first positioning block 6. Blocks 6 are connected. Since the length of the L-shaped plate 13 remains unchanged, the gap between the arc-shaped portion 28 and the side enclosure skin 5 decreases as the telescoping device 14 is extended, so that the gap between the arc-shaped portion 28 and the side enclosure skin 5 and the verticality of the side enclosure skin 5 can be effectively adjusted to a state that meets the technical requirements, thereby ensuring that the verticality of the side enclosure skin 5 meets the technical requirements after assembly, and improving the reliability of welding between the arc-shaped portion 28 and the side enclosure skin 5, that is, between the top enclosure skin 4 and the side enclosure skin 5, as well as the aesthetics and structural stability after welding.
