Example two

This embodiment is substantially similar to the first embodiment, except that:

referring to fig. 6 to 7, the return stroke control assembly includes a movable arm 41 and a gear set 42, a movable slot is provided on the truss 11, the movable arm 41 passes through the movable slot, the movable arm 41 includes a horizontal arm 411 and a vertical arm 412, a rack is provided on a side surface of the vertical arm 412, the gear set 42 includes a first gear and a second gear, the first gear is movably connected with the truss 11 and is engaged with the rack, and the second gear is provided on the rotating shaft 131 and is engaged with the first gear.

In the specific implementation process: after lifting the gate 2, the gate flank 21 is placed on the turnover plate 13, make the gate 2 keep the open state, when needing to put down the gate 2, continue to lift up the gate 2, the flank 21 drives the horizontal arm 411 and the vertical arm 412 upwards moves, the rack of vertical arm 412 drives the first gear rotatory, the first gear drives the second gear rotatory, the second gear drives the turnover plate 13 rotatory, the turnover plate 13 overturns certain angle to the outside, at this moment, put down the gate 2, the flank 21 breaks away from with the horizontal arm 411, the turnover plate 13 is in open state, the gate flank 21 can move down through the turnover plate 13, the torsional spring drives the turnover plate 13 inwards to rotate and reset, the reverse rotation of pivot 131 drives the horizontal arm 411 and the vertical arm 412 resets simultaneously.

It should be noted that the first gear serves to change the rotation direction, and in the view angle of fig. 6, the vertical arm 412 moves upward, the first gear rotates counterclockwise, the second gear rotates clockwise, and the second gear drives the flipping plate 13 to flip outward.

The horizontal arm 411 is connected with the vertical arm 412 through a hinge, and a spring 413 is arranged between the horizontal arm 411 and the vertical arm 412.

The junction of the horizontal arm 411 and the vertical arm 412 is provided with a limiting table for limiting the included angle between the horizontal arm 411 and the vertical arm 412.

In the specific implementation process: the horizontal arm 411 is hinged to the vertical arm 412 to protect the horizontal arm 411 from being damaged by the wing 21 and the horizontal arm 411 if the shutter 2 is moved by a long distance due to carelessness of an operator, and thus the horizontal arm 411 is hinged to the vertical arm 412 and the hinge is rotated to prevent the wing 21 or the horizontal arm 411 from being damaged if the shutter 2 is moved by a long distance. Spring 413 and spacing platform play the effect of tightening up horizontal arm 411 and vertical arm 412 for horizontal arm 411 keeps the contained angle about 90 degrees with vertical arm 412, when flank 21 upward movement, spring 413 tightens up horizontal arm 411, make horizontal arm 411 can not take place the rotation, and drive vertical arm 412 upward movement, only when gate 2 upwards moves the excessive distance of removal when gate 2, spring 413 extension, horizontal arm 411 takes place the rotation, consequently can play the effect that prevents flank 21 or horizontal arm 411 from being impaired.
