[0020] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. The technical solutions in the embodiments of the present invention will be clearly and completely described. The described embodiments are merely some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0021] like Figure 1 , 2 As shown, this utility model patent designs an embodiment of a connector for vertical docking of keel. In this embodiment, the connector includes a first connecting part 11, a second connecting part 12 and an intermediate plate 13. The first connecting part 11 and the second connecting part 12 are respectively located at both ends of the intermediate plate 13. Both are perpendicular to the intermediate plate 13 and located on both sides of the plate body of the intermediate plate 13.

[0022] Both the first connecting part 11 and the second connecting part 12 are U-shaped grooves, with their U-shaped groove openings facing each other. The width of the intermediate plate 13 is smaller than the width of the bottom plates of the first connecting part 11 and the second connecting part 12, and the width difference is not less than the width of the folded portion at the top of the side plate of the transverse C-shaped keel to which the first connecting part 11 is to be inserted. The ends of the two side plates of the first connecting part 11 are chamfered to facilitate quick insertion with the transverse C-shaped keel. In addition, two reinforcing ribs 16 are stamped and formed on the bottom plate of the first connecting part 11.
