Eccentric joint and connecting structure for line pipe and sub steel pipe

The invention relates to an eccentric joint and a connecting structure for a line pipe and a sub steel pipe. The eccentric joint (1) is of an integrated sleeve structure; a front section (11) is a circular section and used for a circular line pipe (2) to extend in; a rear section (12) is a raindrop-shaped section and used for a raindrop-shaped sub steel pipe (3) to be embedded in; the interior ofthe rear section (12) is in smooth transition; and an open groove (13) is formed in the top of the rear section (12). Compared with the prior art, the eccentric joint has the advantages of high machining accuracy, small volume, light weight and convenient mounting; and the working efficiency can also be greatly enhanced in the saddle manufacturing and assembling process. 本发明涉及种偏心接头及线管和分丝管的连接结构，该偏心接头(1)为整体式套筒结构，前段(11)为圆形截面，用于圆形线管(2)的伸入，后段(12)为雨滴型截面，用于雨滴型分丝管(3)的嵌入，后段(12)内部平滑过渡，并且后段(12)顶部设有开口槽(13)。与现有技术相比，本发明的偏心接头加工精度高，体积小，重量轻，安装方便，在鞍座制造组装的过程中也能够大大提高工作效。
