A connection mechanism includes fixing seats, rotary seats, and transmission gears. Each of the fixing seats includes base and shaft holes provided at two sides of the arc-shaped base. The rotary seats and the transmission gears are clamped between two adjacent fixing seats. Each of the rotary seats includes a seat body, an arc-shaped groove longitudinally penetrating through the seat body, and a teeth structure formed by laterally extending from a middle portion of the seat body below the arc-shaped groove. Each of the two transmission gears includes a rotation shaft and a gear fixed onto the rotation shaft and engaged with the teeth structure, wherein the rotation shaft passes through the arc-shaped groove and includes two ends respectively limited inside the shaft holes of two adjacent fixing seats.

Connection mechanism, foldable display device and communication device

Disclosed is a tube lamp, comprising a mounting box and a lamp body matched with the mounting box, the mounting box comprising a top plate and side wall boards around the top plate; the tube lamp also comprises a fixed board; the fixed board comprises a fixed board body; at least two sets of fasteners are disposed at the two ends of the fixed board body; the fasteners are interspaced; the fixed board is detachably connected to the mounting box through the fasteners; and the lamp body is connected to the mounting box through the fixed board. At least two sets of fasteners are disposed at the two ends of the fixed board body; the fasteners are used for connection with the mounting box; the two sets of fasteners are interspaced, capable of being applied to many mounting boxes of different sizes, so the tube lamp has higher compatibility.
