The invention discloses a van trailer connecting piece, and belongs to the field of trailer connecting pieces, the van trailer connecting piece comprises a lower clamping frame, wherein the lower clamping frame is hollow and the upper part of the lower clamping frame is open; one side of an upper opening of the lower clamping frame is connected with a first vertical plate; the other side of the upper opening of the lower clamping frame is connected with a second vertical plate; a side supporting frame is arranged on the side wall, away from the second vertical plate, of the first vertical plate and is hollow, and the left side of the side supporting frame is open; first connecting pin holes are formed in the corresponding positions of the front side wall and the rear side wall of the side supporting frame. Through the matching effect of the lower clamping frame, the first vertical plate, the second vertical plate and the side supporting frame, the cross beam and the longitudinal beam of the frame can be connected so that the cross beam and the longitudinal beam can be positioned and connected according to the angle between the lower clamping frame and the side supporting frame; through the connection of connecting structures such as the connecting pins, the cross beams and the longitudinal beams are detachable, so that the later adjustment and repair are facilitated; and structures such as holes are preset, so that the mounting precision between the cross beams and the longitudinal beams is higher.
本发明公开了一种厢式挂车连接件,属于挂车连接件领域,包括:下卡框,所述下卡框为中空且上部开口状;所述下卡框的上部开口一侧连接有第一立板;所述下卡框的上部开口另一侧连接有第二立板;所述第一立板背离第二立板的一侧壁设置有侧支撑框,所述侧支撑框为中空且左侧开口状;所述侧支撑框的前后侧壁对应位置均开设有第一连接销孔。通过下卡框、第一立板、第二立板、侧支撑框的配合作用,能够对车架的横梁和纵梁连接,使得横梁和纵梁之间能够按照下卡框、侧支撑框之间的角度定位连接;通过连接销等连接结构的连接,使得横梁和纵梁之间可拆卸,从而方便后期的调整和修复;预先设定好的各个孔等结构,使得横梁和纵梁之间的安装精度较高。
