Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Referring to fig. 1-4, the present invention provides a technical solution: the utility model provides a large-scale mechanical cab is with board of making an uproar that falls, including 1 opening part articulated flap gate 8 of curb plate and curb plate, 1 outside butt of curb plate has baffle 6, it has L shape to rotate handle 7 to run through the rotation on the

curb plate

1, 6 both sides of baffle all are fixed with the pothook 5 that cooperation L shape rotated handle 7 joint, two inside grooves 2 have been seted up on curb plate 1, all be provided with parallel link mechanism in two inside grooves 2, it is parallel with 1 outer wall of curb plate to be used for driving baffle 6, wherein, baffle 6 is at the in-process of the 1 outside upset of curb plate, keep the parallel between baffle 6 and the curb plate 1 throughout, make baffle 6 avoid producing slope and gap.

Specifically, as shown in fig. 2, the parallel link mechanism includes two links 3 rotatably connected to the inner groove 2, and free ends of the two links 3 are rotatably connected to the baffle 6, so that the parallel link mechanism limits a movement track of the baffle 6 on an outer side of the side plate 1.

Specifically, as shown in fig. 2, the two connecting rods 3 are parallel and equally long, so that the baffle 6 and the side plate 1 are always parallel.

Specifically, as shown in fig. 4, a bevel notch 11 that is matched with the flap door 8 for abutting against is formed in the side plate 1, and a rubber pad 9 that abuts against the bevel notch 11 is bonded to the flap door 8, wherein the rubber pad 9 is used for buffering the door closing impact of the flap door 8 and the bevel notch 11.
