[0025] To make the content of this utility model easier to be clearly understood, the following will clearly and completely describe the technical solutions in the embodiments of this utility model with reference to the accompanying drawings in the embodiments of this utility model.

[0026] Please refer specifically to the attached Figures 1-5 This application discloses a flip protection cover structure, including a protective rubber strip 1, a protection cover 2, a nut 3, a gasket 4, a pin shaft 5, an oil cylinder pin shaft 6, a leg 7, a leg oil cylinder 8, a leg pin shaft 9, a frame pin shaft 10, a seat plate 11, and a frame 12.

[0027] Both ends of the frame are provided with connecting feet. Legs are hinged on both sides of the connecting feet. Seat plates are provided near the top of the connecting feet close to both legs. Protection covers are hinged on the seat plates. The protection covers are sleeved on the upper part of the legs. A protective rubber strip is connected to one end of the protection cover close to the leg. A leg pin shaft is provided at the bottom end of the connecting foot to cooperate with the leg. An oil cylinder is also hinged inside the leg. A frame pin shaft for hinging with the free end of the oil cylinder is provided on the frame above the leg pin shaft.

[0028] The specific connection method is as follows: The leg 7 is hinged to the frame 12 through the leg pin shaft 9. The rod end of the leg oil cylinder 8 is hinged inside the leg 7 through the oil cylinder pin shaft 6. The other end cylinder barrel of the leg oil cylinder 8 is hinged inside the frame 12 through the frame pin shaft 10. The seat plate 11 is welded at a suitable position on the frame 12. The protective rubber strip 1 is snapped into the front part of the protection cover 2. The protection cover 2 is hinged to the seat plate 11 through the pin shaft 5. The pin shaft 5 passes through the gasket 4 and the nut 3.

[0029] More specifically, the protection cover includes an upper plate and vertical plates respectively connected and arranged vertically downward on both sides of the bottom of the upper plate. A channel for cooperating with the leg is formed between the upper plate and the vertical plates. The protective rubber strip 1 is snapped into one end of the upper plate.

[0030] When the leg is in the lowered position, the protective rubber strip at the front of the protection cover closely adheres to the leg surface by its own weight. When the leg is raised, the protection cover is also raised under the lifting force of the leg. Since only the rubber strip closely adheres to the leg surface, the phenomenon of scraping off the paint on the leg is avoided. When the leg is lifted to the highest position, the limit plate of the protection cover touches the limit position of the seat plate, avoiding the protection cover from continuing to flip backward due to inertia and interfering with the protection cover on the other side, and also avoiding the protection cover from flipping over too much and the direction of its own weight changing.
