Self-lock device for vehicle inclined placed on plate of multi-storey garage

The utility model relates to a solid parking garage parking plate flat topping raise lean self locking system, which comprises a main cylinder, a parking plate and a rack, the parking plate, the rack and one point of the main cylinder is hinge linked adopting a triple coaxial way, another end of the main cylinder links a pair of connecting bar, the main cylinder and one point of each connecting bar is hinge linked adopting a triple coaxial way, another point of each connecting bar is separately hinge linked with the parking plate and the rack by adopting a diad coaxial way. A vice cylinder can be arranged between the parking plate and the rack. During the process that main cylinder piston rod push and pull the double connecting bar middle hinge joint point, the main cylinder and the vice cylinder are mutually coordinated, the double connecting bar another two ends hinge joint points will be shoved off, folded, the parking plate do up and down movement revolved around the bracket central, to reach the overhead oblique parking position and horizontal turnover position, the double connecting bar, parking plate and the bracket constitute a steady triangle, to make the oblique parking plate locate at a machine self locking mode, vehicle storage is very safe.
