Vehicle door limiting mechanism of crawler-type amphibious all-terrain vehicle

The invention discloses a vehicle door limiting mechanism of a crawler-type amphibious all-terrain vehicle, which belongs to the technical field of all-terrain vehicles, and comprises a pulley mounting plate mounted on a vehicle door, a pulley is arranged on the pulley mounting plate, and the pulley is connected with a limiting frame mounting seat mounted on a door frame of the vehicle door through a limiting frame; the limiting frame is of an 8-shaped ring structure formed by high-strength spring steel, and the pulley slides in the limiting frame to limit the vehicle door. The limiting frame is of an 8-shaped ring structure formed by high-strength spring steel, the shape of a sliding rail on the structure is changed through elastic deformation of steel to limit a pulley on a vehicle door, and therefore the purpose of limiting the vehicle door is achieved. The limiting position of the automobile door can be changed by changing the length of the limiting frame, and meanwhile the limiting frame can be replaced
