Detailed Description

The present application is described in further detail below in conjunction with the drawings attached to the specification.

Referring to fig. 1, 2 and 4, embodiments of the present application disclose a lift gate comprising a door for lifting material

Lifting the frame 1;

a protection plate 2; the protection board 2 is in rotary fit with the lifting frame 1 through a rotary piece 3;

the fixing column 4 is matched with the protection board 2 in a clamping way through a fixing frame 5, and the fixing frame 5 is fixedly connected with the protection board 2;

the end part of the protection board 2 is matched with the lifting frame 1 in a clamping way through the fixing column 4 and the fixing frame 5.

In the above embodiment, the protection board 2 can be rotated to the side edge of the lifting frame 1, so that the risk that the door plate falls down in the prior art is avoided, and the safety is higher.

Referring to fig. 2, the rotating member 3 includes a limiting plate 6 fixedly connected with an outer wall of the protecting plate 2, a limiting frame 7 slidably fitted outside the limiting plate 6, a rotating plate 8 fixedly connected with an end of the limiting frame 7, a rotating groove 9 provided on an outer wall of the lifting frame 1, and the rotating plate 8 rotatably connected with the rotating groove 9, wherein the limiting frame 7 and the rotating plate 8 are arranged in an inclined manner.

In the above embodiment, the protection plate 2 can be rotated to the side of the lifting frame 1, and the occupation area of the protection plate is reduced.

Referring to fig. 3, the rotating member 3 further includes a rotating rod 10 rotatably connected with the outer wall of the protection plate 2 through a hinge, a connecting block 11 is fixedly connected to the end of the rotating rod 10, a straight spring 12 is hinged to the end of the connecting block 11 through the hinge, the other end of the straight spring 12 is rotatably connected with the lifting frame 1, and the connecting block 11 is rotatably connected with the lifting frame 1 through a rotating shaft.

In the above embodiment, the provision of the straight spring 12 can assist the user in opening and closing the protection plate 2.
