[0023] Example: Reference Figure 1-5 A pneumatic door opening frame mechanism is shown, comprising a cargo box frame 1 and a cargo box door. The top surface of the cargo box frame 1 is hinged with the cargo box door, and a U-shaped clamp is provided at the bottom of the cargo box door. The mounting member 2 is welded to the inner side of the cargo box frame 1, and a through hole 11 is provided on the cargo box frame 1. An L-shaped hook 3 provided on the mounting member 2 passes through the through hole 11. A connecting rod 5 is hinged at the bottom of the mounting member 2, and a U-shaped hanger 7 is hinged to its outer end, and a telescopic end of a cylinder 4 is hinged to its inner end. The cylinder 4 is installed on the mounting member 2. The cylinder 4 is used to drive the connecting rod 5 to move (rotate with the hinge point of the connecting rod 5 and the mounting member 2 as the center of the circle), so that the distance between the free end of the connecting rod 5 and the hook 3 is shortened, and the hanger 7 is moved so that the hinged hanger 7 is placed on the hook 3, thereby limiting the clamp, and then the telescopic end of the cylinder 4 is retracted to move the hanger 7 downward, thereby completing the limitation of the cargo box door.

[0024] Mounting part 2: The sheet metal body 21 is a V-shaped plate, and a sheet metal back plate 22 is welded at its V-shaped mouth. The sheet metal back plate 22 is used to install the cylinder 4, and a U-shaped mouth is provided at the bottom of the sheet metal back plate 22. The U-shaped mouth is used for the telescopic end of the cylinder 4 to pass through to control the movement state of the connecting rod 5. Two groups of symmetrically arranged connecting blocks 23 are provided at the bottom outer end of the sheet metal body 21. The connecting plates 5 are hinged between the connecting blocks 23, and a hook 3 is provided on the end face of the sheet metal body 21.

[0025] The cylinder 4 is replaced with a spring, and the spring has the ability to automatically lock and reset when working.
