Van-type truck rear door lock mechanism

Abstract

The invention belongs to the field of van-type truck rear door lock mechanisms, and particularly relates to a van-type truck rear door lock mechanism. The van-type truck rear door lock mechanism comprises a cargo car body, door leaves, rotating shafts, clamping blocks, a fixing block, a positioning block, a swinging block, a sliding rod, a sliding pin, a circular sleeve, a limiting block, a limiting spring and the like, wherein two vertical rotating shafts are symmetrically installed on the two door leaves of the rear door of the cargo car body, and the rotating shafts are correspondingly androtatably matched with three supports installed on the door leaves. According to the van-type truck rear door lock mechanism, through the matching of the limiting block and arc grooves on two clampingblocks on the same side of the rotating shafts, the door leaves of the cargo car body which are closed automatically under the action of wind force are locked, the reciprocating switch swing of the two door leaves of the cargo car body due to road bump when a driver drives on the road without checking whether the door leaves of the cargo car body are closed is avoided, thus the cargoes in the cargo car body are effectively prevented from falling and being damaged due to the form road drop bump, and the freight economic loss is reduced.

Description

technical field [0001] The invention belongs to the field of a rear door lock mechanism of a van, in particular to a rear door lock mechanism of a van. Background technique [0002] For existing vans without the self-locking function of the rear door, when the rear door is closed by strong wind or unintentional artificially after the loading is completed, the closed rear door is not locked, and the driver of the truck forgets to check the cargo compartment when he gets on the vehicle and drives on the road. Whether the back door is closed. When encountering a relatively bumpy road, the goods in the cargo compartment are likely to fall from the rear door due to the bumps, resulting in losses. Simultaneously, the door leaf of the cargo compartment that opens and closes due to bumps and swings poses a certain threat to the safety of pedestrians or other vehicles, and has a relatively large potential safety hazard. [0003] For a van with a self-locking function on the rear do...

AI Technical Summary

Problems solved by technology

If the work of loading and unloading the goods is all undertaken by the driver alone, the driver who is locked in the compartment cannot get help from others in time, which will inevitably affect the loading, unloading and timely delivery of the goods.
