Double-stroke positioning door opening mechanism

The invention relates to the field of forklifts and particularly discloses a double-stroke positioning door opening mechanism. The double-stroke positioning door opening mechanism comprises a gas spring, a rotating member and a baffle. One end of the rotating member is pivoted to an overhead guard of a forklift, and the other end of the rotating member is provided with a bar-shaped groove; the movable end of the gas spring is movably mounted inside the bar-shaped groove, and the fixed end of the gas spring is pivoted to a forklift door; the baffle is fixedly mounted on the overhead guard of the forklift and on one side of the rotating member, which is away from the rotating center of the forklift door. The double-stroke positioning door opening mechanism achieves a door opening function at a larger angle as well as a smaller angle, thereby having the advantages of being large in application range, high technological performance, simple in structure, low in cost and the like.
