Anti-collision van rear door lock device
The invention belongs to the field of van rear door locks, and particularly relates to an anti-collision van rear door lock device. The anti-collision van rear door lock device comprises shafts A, shafts B, limiting blocks A, springs A, thin steel wires A, winding wheels, swing rods, U-shaped bases, 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 van rear door, and each shaft A is in rotary fit with two supports installed on the corresponding door leaf; andwhen the two shafts A in the anti-collision van rear door lock device deform due to collision and cannot be rotationally unlocked through 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, a shifting rod on a shifting shaft C drives the four clamping blocks on a cylindrical head to be rotationally unlocked, and then the door leaves of a van 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，尤其涉及一种防撞厢式货车后门锁装置，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。
