The universal aviation folding vehicle provided by the invention has the advantages that:

1. universality: the turning plate and the wine rack body can be increased or decreased without affecting other structures, and the model is simple and convenient to manage;

2. number of shelves: flexibly increasing and decreasing shelves serving as middle turning plates in the main bracket;

3. the reliability is high: the mechanism for locking the side turning plate is mechanically connected, so that the deformation caused by welding is avoided, meanwhile, the pressing plate of the pressing type is higher in reliability through manual operation, even if the torsion spring fails, the side turning plate can be locked by the gravity of the pressing plate due to the fact that the gravity center of the pressing plate is on the outer side, and the side turning plate can be still folded after being pressed;

4. the folding vehicle has compact structure: the T-shaped hinge is adopted, so that the number of parts is reduced, the folding size of the folding trolley is smaller, the assembly procedures are correspondingly reduced, and the maintenance is relatively simple.

The invention aims to provide a folding vehicle which is lighter, more reliable and more space-upgrading for an airline company, and the turning plate and the wine rack can be freely increased or decreased according to the requirements of customers.

Different customers or different models all lead to folding car size multiple in daily sales process, consequently need a general type folding car to satisfy different customers' different demands, because the same vast majority of spare parts of structure can exchange generally, so saved production and maintenance cost greatly, single model also makes the producer more convenient to type management simultaneously.
