Anti-loose container fixing semi-trailer

Abstract

This utility model discloses a container-fixing semi-trailer for preventing loosening, comprising a frame with a bearing surface for carrying a container. Corner fixing seats are fixedly installed at the four corners of the frame. The top of each corner fixing seat has a right-angle limiting groove communicating with the adjacent two sides. Each corner fixing seat has a first locking pin hole, in which a first rotary locking pin for fixing the container is installed. At least one set of side fixing seats are arranged symmetrically on both sides of the bearing surface along the length of the frame. Each side fixing seat has an L-shaped limiting groove opening towards the inside of the frame. Each side fixing seat also has a second locking pin hole, in which a second rotary locking pin for fixing the container is installed. Both the corner fixing seats and the side fixing seats are welded with rope loops, which are symmetrically distributed along the length of the frame on the outer sides of the corner fixing seats and the side fixing seats. This design effectively improves the container fixation of the semi-trailer.
