The invention belongs to the technical field of logistics transportation, and particularly relates to a logistics semitrailer device which comprises a frame and a box body; the box body is installed on the upper surface of the frame, supporting plates are symmetrically and rotationally connected to the upper surface of the frame, connecting pieces are fixedly connected to the end faces of the supporting plates, and connecting plates are installed on the outer side walls of the two ends of the box body. A fixing block drives an inserting plate to move synchronously until the distance between the inserting plate and the fixing plate is larger than the width of the bottom ends of the T-shaped plate, the T-shaped plate is inserted between the inserting plate and the fixing plate and gets closeto the fixing plate, a fixing rod stretches out to drive the inserting plate to reset, the sliding plate and the clamping plate are inserted into inserting grooves, and splicing and fixing of the inserting plate and the fixing plate are completed. Due to the fact that the inserting plate and the fixing plate form the U-shaped structure and the T-shaped plate is in the T shape; under cooperation,the T-shaped plate is locked and fixed, so that connection between the frame and the box body is firm; in conclusion, the fixing mode is simple, and the firmness between the frame and the box body isimproved.
本发明属于物流运输技术领域,尤其为一种物流半挂车装置,包括车架和箱体,所述箱体安装在所述车架的上表面,所述车架的上表面对称转动连接有支撑板,所述支撑板的端面固定连接有连接件,所述箱体的两端外侧壁安装有连接板;固定块带动插入板同步移动,直至移动至插入板和固定板之间的间距大于T型板底端的宽度,T型板插入插入板和固定板之间,并向固定板靠近,固定杆伸出,带动插入板复位,将滑板和卡板插入插槽的内部,完成插入板和固定板的拼接固定,因插入板和固定板构成凹字形结构,且T型板为T型,相互配合,对T型板锁死固定,使得车架与箱体之间的连接牢固,综上所述,固定方式简单,且提高了车架与箱体之间的牢固度。
