The invention discloses a drawing combined structure. The drawing combined structure comprises N layers of bottom beam frames and N-1 one-way drawing slideways which are sequentially stacked from topto bottom; any two adjacent layers of the bottom beam frames are in sliding connection through a one-way drawing slideway structure, and the sliding directions of the N layers of the bottom beam frames are consistent, so that front and back one-way drawing is realized; each bottom beam frame comprises a left frame, a middle frame and a right frame; and the left frames and the right frames are nested in the middle frames, so that left-right bidirectional drawing of the bottom beam frames is achieved. According to the drawing combined structure, a function structure of changing a bottom beam from one to three can be realized through left-right bidirectional drawing. A one-to-three left-right drawing combination is regarded as an independent body, and then a multi-layer structure can be formed through a longitudinal open type slideway, so that infinite possibility is provided for space utilization; and the drawing combined structure can be applied to the fields of mobile houses, folding recreational vehicle transformation, whole recreational vehicle production and children educational toys.
本发明公开了一种抽拉组合的结构,包括自上而下依次叠加的N层底梁框架和N‑1个单向抽拉滑道;任意相邻两层底梁框架之间通过一个单向抽拉滑道结构滑动连接,且所述N层底梁框架滑动方向一致;并实现前后单向抽拉;每一所述底梁框架包括:左框架、中框架和右框架;所述左、右框架嵌套在中框架内,实现底梁框架的左右双向抽拉。该发明可通过左右双向抽拉,实现底梁由一变三的功能结构。将此由一变三的左右抽拉组合视为一个单独个体,再通过纵向开放式滑道,可形成多层结构,为空间利用提供无限可能性;可应用于活动房领域、折叠房车改造领域、房车整车生产领域和儿童益智玩具领域。
