As shown in fig. 1, 2 and 3, the reinforced side rail assembly for a cargo vehicle of the present invention comprises a side rail, a side rail bracket 2, a connecting plate 3, a locking groove 4 and a detachable connector.
Wherein, the side guardrail includes guardrail horizontal pole 1, and guardrail horizontal pole 1 is provided with hollow groove 10 along its length direction, and the upper and lower both ends of hollow groove 10 are inwards equipped with bending section 9.
The side guardrail supports 2 are vertically arranged, the upper half parts of the side guardrail supports 2 are connected to the upper part of the truck, and the lower half parts of the side guardrail supports are connected to the guardrail cross rod 1.
The connecting plate 3 is arranged inside the hollow groove 10 and is blocked by the bending section 9, two sides of the connecting plate 3 are respectively bent into flanges 31 in the hollow groove 10, and the flanges 31 are vertically arranged in the hollow groove 10. In particular, the web 3 and the flanges 31 form a channel-shaped element which increases its strength and thus reduces its deformation under stress.
The connecting plate 3, the locking groove 4 and the side guardrail support 2 are connected through a detachable connecting piece.
Further, as shown in fig. 3, in the locking state, gaps are preset between the upper and lower ends of the hollow groove 10 and the upper and lower edges 42 of the locking groove 4, respectively, and the two bent sections 9 of the hollow groove 10 are closely attached to the web 41 of the locking groove 4.

Further, the length of the connecting plate 3 is greater than the distance between the two bending sections 9 of the hollow groove 10, and the side wall of the connecting plate 3 is tightly attached to the two bending sections 9 of the hollow groove 10. Because the length of connecting plate 3 is greater than the distance between two sections 9 of bending of hollow groove 10, consequently, connecting plate 3 can be vertical to be set up in hollow groove 10, promptly when locking state, and connecting plate 3 can not remove to the outside of hollow groove 10 under blockking of two sections 9 of bending of hollow groove 10 for connecting 3 can play the effect of connecting with the slider better in the inside of hollow groove 10.
Further, the width of the connecting plate 3 is smaller than the distance between the two bending sections 9 of the hollow groove 10. Because the van strenghthened type side guardrail assembly in this embodiment is detachable, consequently connecting plate 3 can freely take out or put into hollow groove 10, when the width of connecting plate 3 is less than two distance between the section 9 of bending of hollow groove 10, can be when van strenghthened type side guardrail assembly needs to be dismantled or install, will place connecting plate 3 level earlier, then take out or put into hollow groove 10 with it again.
Furthermore, the upper and lower ends of the connecting plate 3 are abutted against the inner walls of the upper and lower ends of the hollow groove 10. Because the upper and lower ends of the hollow groove 10 of the guardrail cross bar 1 are positioned between the two edges 42 of the locking groove 4, and the locking groove 4 is not deformed, the upper and lower ends of the hollow groove 10 in the range covered by the locking groove 4 are not deformed, and the connecting plate 3 is clamped between the inner walls of the upper and lower ends of the hollow groove 10, so that the connecting plate 3 cannot fall off. That is, the locking groove 4 allows the deformation of the barrier rail 1 to be reduced, thereby further ensuring that the connecting plate 3 is not disengaged.
Preferably, the locking groove 4 is made of a T600 high strength steel plate, and the coupling plate 3 is made of a Q235 common steel plate.
Further, the detachable connection may be a bolt connection, a snap connection, or the like. The detachable connection in this embodiment is a bolt set, which includes a bolt 5 and a nut 6.
