A new type of semi-trailer box

Abstract

The invention belongs to the field of semitrailers, in particular to a novel semitrailer carriage. In view of the problems that an existing semitrailer carriage is fixed in structure, different side box plates are inconvenient to assemble and install, and the side box plates cannot be adjusted according to the loading requirements, the following scheme is proposed: the novel semitrailer carriage comprises a box body; four fixed box plates are fixedly mounted at the top of the box body; two fixing grooves are formed in the top of the box body; movable box plates are slidably mounted in the twofixing grooves correspondingly; two limiting grooves are formed in the inner walls of the two sides of the fixing groove correspondingly; grooves are formed in the two sides of the movable box plate correspondingly; limiting rods are slidably mounted in the two grooves correspondingly; the limiting rods are matched with the corresponding limiting grooves; and mounting grooves are formed in the twosides of the movable box plate correspondingly. The semitrailer carriage is reasonable in structure and convenient to operate, the semitrailer carriage is flexible in structure, the shapes of the carriage bodies in different use states can be flexibly adjusted, and the carriage bodies can be adjusted according to loading requirements.

Description

technical field [0001] The invention relates to the technical field of semi-trailers, in particular to a novel semi-trailer box. Background technique [0002] A semi-trailer is a trailer whose axle is placed behind the center of gravity of the vehicle and is equipped with a coupling device that can transmit horizontal and vertical forces to the tractor. The semi-trailer is generally a three-axle semi-trailer. Thirteen-meter warehouse fences, low-bed semi-trailers, etc., are heavy-duty transportation vehicles that are connected to the head of the semi-trailer through traction pins. Compared with "monolithic" vehicles, semi-trailers can improve road transportation. comprehensive economic benefits. The transportation efficiency can be increased by 30-50%, and the cost can be reduced by 30-40%; [0003] However, the structure of the existing semi-trailer compartment is fixed, which is inconvenient for the combined installation of different side box panels, and cannot be adjust...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to solve the shortcomings in the prior art that the structure of the semi-trailer compartment is fixed, it is not convenient to combine and install different side box panels, and the side box panels cannot be adjusted according to the loading requirements, and a new type of semi-trailer is proposed. carriage
