The invention belongs to the field of rear door locks of vans, and particularly relates to an anti-collision rear door lock device for a van. The anti-collision rear door lock device for the van comprises shafts A, shafts B, limiting blocks A, springs A, thin steel wires A, winding wheels, swing rods, U-shaped seats, cross universal joints, shafts C, clamping blocks, limiting blocks B, springs B and the like, wherein the two vertical hollow shafts A are symmetrically installed on two door leaves of a rear door of the van, and each shaft A is rotationally matched with two supports mounted on the corresponding door leaf. When the two shafts A deform due to collision and cannot be unlocked through rotation of the swing rods, the swing rods are swung upwards by a large margin to drive the two limiting blocks A on the shafts A to relieve relative rotation limitation of the shafts A and the two corresponding shafts B, it is guaranteed that shifting rods on the shafts C are shifted to drive four clamping blocks on cylindrical heads to rotate and unlock, and then it is guaranteed that the door leaves of the cargo compartment can still be smoothly opened under the condition that the shafts A deform due to collision.

    本发明属于厢式货车后门锁领域,尤其涉及一种防撞的厢式货车用的后门锁装置,它包括轴A、轴B、限位块A、弹簧A、细钢丝A、缠绕轮、摆杆、U型座、十字万向节、轴C、卡块、限位块B和弹簧B等,其中货厢后门的两个门扇上对称安装有两个竖直的中空轴A,每个轴A均与安装在门扇上的两个支座旋转配合;当本发明中的两个轴A因碰撞发生形变而不能通过摆杆旋转解锁时,通过向上大幅度摆动摆杆带动轴A上的两个限位块A解除轴A与相应两个轴B的相对旋转限制,保证通过拨动轴C上的拨杆带动圆柱头上的四个卡块旋转解锁,进而保证在轴A因发生碰撞发生形变情况下依然可以顺利地将货厢的门扇打开。
