Description

Technical Field

[0001] This utility model relates to the field of semi-trailer technology, and in particular to a side curtain box type semi-trailer. Background Technology

[0002] Over the years, the overall structure of box semi-trailers has undergone significant changes. For example, it has gradually expanded from the original fully enclosed structure with a single frame and skin to a frameless, semi-enclosed structure with large corrugated panels, and soft-top box trucks with tarpaulins replacing the roof. Currently, some truck bodies are covered with tarpaulins. On the one hand, the tarpaulin itself has no support and is only fixed to the truck body by the sides, which is cumbersome, has low safety, and poor waterproofing. On the other hand, opening the tarpaulin generally requires manual pulling, which consumes a lot of manpower for long truck bodies, resulting in low automation.

[0003] To address the aforementioned issues, existing patent (CN206841282U) discloses a side-curtain semi-trailer. This side-curtain semi-trailer includes a chassis, a box body, a sliding side curtain mechanism, and a motor. The sliding side curtain mechanism comprises an annular track surrounding the left and right sides of the box body. Grooved wheels are positioned at the corners of the annular track, with steel wire ropes wound around them. A grooved wheel at one corner of the bottom of the annular track is fixedly connected to the motor drive shaft. A side curtain frame is installed within the annular track, including vertical rods. Rollers are fixed to the upper and lower ends of the vertical rods, and these Rollers cooperate with the annular track. One end of the vertical rod on one side of the box body is fixed to the steel wire rope. Symmetrical track fixing frames are arranged on the upper and lower sides of the annular track, and an integrated water-blocking plate is installed on the outer side of the track fixing frames. The advantages of this invention are that the side-curtain semi-trailer has a stable overall structure, simple fixing, good waterproofing, and a high level of automation, making it suitable for widespread application.

[0004] However, in the aforementioned existing technologies, when the side curtain structure is installed on a semi-trailer, it needs to be customized according to the size of the semi-trailer, which makes it inconvenient to mass-produce the side curtain structure and reduces the convenience of using the side curtain structure. Summary of the Invention
