The middle part of the door core plate is bent forwards to form a side V-shaped plate, two sides of the side V-shaped plate are respectively provided with an inner reinforcing support and an outer reinforcing support, and the inner reinforcing support, the outer reinforcing support and the blocking plate are arranged in parallel.
Based on the above, for better reinforcing support, the cross section of the inner reinforcing support is triangular.
Based on the above, the cross section of the outer reinforcing brace is a right trapezoid.
Based on the above, in order to increase the intensity at side U-shaped plate rear portion, the closure plate is the right-angle plate of personally submitting the L shape in cross section, one side laminating of right-angle plate is in the inboard top of side U-shaped plate, the another side laminating of right-angle plate is in the rear side of said chamber door core.
Based on the above, in order to facilitate the installation and the turnover of the trailer box plate, the side U-shaped plate at the lower side is provided with a hinge.
Based on the above, the side U-shaped plate located at the upper side is provided with the locking device.
Based on the above, the locking device is a snap lock.
The utility model also provides a semitrailer, which is provided with the trailer box plate.
Compared with the prior art, the utility model has substantive characteristics and progress, and particularly, the trailer box board provided by the utility model has the advantages that the door core board and the upper and lower frames are integrally formed, the existing step of welding the upper and lower side frames on the upper and lower sides of the door core board is avoided, meanwhile, the thickness of the door core board can be adjusted according to different types of goods sources, the door core board can be reinforced by welding vertical supports according to the needs, the requirements of various trailer box board strengths are met, and meanwhile, the semi-trailer box board has good sealing performance. The utility model also provides a semitrailer provided with the trailer box plate, and the semitrailer has less welding workload.
