Description

Technical Field

[0001] This utility model relates to the technical field of semi-trailers, specifically to curtain-side semi-trailers. Background Technology

[0002] Curtain trailers are a type of trailer widely used in Europe but relatively rare in China. They use curtains instead of the box material of other trailers, and the internal structure is mostly made of aluminum alloy. They also use air suspension technology, making them lighter. Compared with ordinary box trailers or van trailers, they can be 3-4 tons lighter. Since the curtains on the top and sides of the curtain trailer can be fully opened, multiple forklifts can operate at the same time, resulting in higher loading and unloading efficiency. They also use standard palletized transportation, which can maximize the use of space and make the cargo layout more even and reasonable. The load can be evenly distributed to each axle, reducing the possibility of excessive wear on certain chassis components.

[0003] Currently, the opening and closing of the curtains on existing side-curtain semi-trailers are all done manually. Before loading the cargo, the staff first manually opens the upper and lower tightening structures of the curtain, then opens the front and rear tightening mechanisms, then opens the curtain from one end of the vehicle to the other, and finally removes the crossbars and side sliding pillars on both sides of the side-curtain semi-trailer. Only after completing the above operations can loading begin. After the cargo is loaded, the above steps need to be repeated to manually close the side curtain, which is quite cumbersome. Utility Model Content

[0004] In order to solve the problem that the opening and closing process of the curtains in existing side curtain semi-trailers is relatively cumbersome, the purpose of this utility model is to provide a side curtain semi-trailer.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: a side curtain semi-trailer, including a cargo box floor, a cargo box side plate fixedly installed on the upper surface of one end of the cargo box floor, a cargo box top plate fixedly installed on the end of the cargo box side plate away from the cargo box floor, a first positioning plate fixedly installed on the upper surface of the cargo box top plate, a first connecting rod rotatably installed on the first positioning plate, a second positioning plate fixedly installed on one end of the first positioning plate, a second connecting rod rotatably installed on the second positioning plate, a third positioning plate fixedly installed on the end of the first positioning plate away from the second positioning plate, a third connecting rod rotatably installed on the third positioning plate, and a first bevel gear fixedly installed on the first connecting rod.

[0006] Preferably, a second bevel gear is fixedly provided at one end of the second connecting rod near the first bevel gear, and the second bevel gear meshes with the first bevel gear. A third bevel gear is fixedly provided at one end of the third connecting rod near the first bevel gear, and the third bevel gear meshes with the first bevel gear.
