The utility model relates to a bed frame group, which comprises a base, a movable seat and a first linkage mechanism, the movable seat can reciprocate on the base.The first linkage mechanism includes a follower, a connecting rod, a swing arm and a first oil pressure pump. The connecting rod and the follower are connected to the movable seat. The two ends of the swing arm are respectively connected with the base and the connecting rod. The pivot end of the first oil pressure pump is connected with the base, and the extension end is connected with the swing arm. It is determined that the swing arm drives the connecting rod up, drives the movable seat to move at the base, and the follower remains inclined. State, to achieve the bed frame group displacement effect more stable and smooth, both quick maintenance function.一種床架組，包括一底座、一活動座與一第一連動機構，該活動座在底座上可往復運動。該第一連動機構包括一從動件、一連桿、一擺臂與一第一油壓泵，該連桿與從動件連接於活動座上，該擺臂二端分別樞接底座與連桿，該第一油壓泵的樞接端與底座相連，伸縮端樞接於擺臂，決定擺臂驅使連桿上揚，帶動活動座在底座位移，連帶從動件保持傾斜狀態，達到床架組的位移效果更加平穩和流暢，兼具維修快捷功能。
