The invention discloses a telescopic fan blade with fixed beads. The telescopic fan blade comprises the fixed beads, a fixed bead frame, a plurality of contact sliding blocks and two or more stages oflimiting clamping buckle latches, and is characterized in that the fixed bead frame is connected with each section of telescopic fan blade sliding way to form a limiting buckle; the fixed beads are arranged on the fixed bead frame or the limiting clamping buckle latches in a fixed-shaft connection or shaftless framing sleeving mode to slidably make contact with fan blade bodies; the multiple contact sliding blocks are arranged on the surfaces and the sliding ways of the telescopic fan blade bodies; the limiting clamping buckle latches are fixedly connected to all the sections of telescopic fan blade sliding ways to form one or more stages of buckle secondary anti-loosening, wherein the two or more limiting clamping buckle latches are linearly arrayed; through cross section plugs at one ends of sleeves, non-deformation and anti-de-buckling of the fan blade bodies are reinforced; the fan blade bodies reduce friction and reinforce bending resistance through the fixed beads, blocks, pit grooves or T-shaped bars, the plastic, rubber or graphite contact sliding blocks and a fan blade adhering lubricant or graphite powder slidably makes contact with the fan blade bodies to reduce friction, and the strip-shaped contact sliding blocks outwards bulge or inwards bulge to slidably make contact with and clean the fan blade bodies; and the fan blade bodies are connected with an anti-loosening insurance, multi-stage buckle anti-loosening and insurance cable anti-loosening are achieved, a power supply is automatically turned off during de-buckling, the telescopic range of the fan blade bodies is enlarged without increasing the diameter of a lamp, and the lamp is flexibly matched.

    定珠伸缩风扇叶片,包括:定珠、定珠架、多个触点滑块和最少两级限位卡止搭扣;特征是:定珠架连接每节伸缩扇叶滑道成限位卡扣;定珠定轴连接或无轴框套在定珠架或限位卡止搭扣上滑触扇叶;多个触点滑块设在伸缩扇叶的表面和滑道;限位卡止搭扣固定连接在每节伸缩扇叶滑道并分别最少直线阵列二个,形成最少一级卡扣二级防脱;套管一端横截面封塞加强扇叶不变形防脱扣;扇叶用定珠、墩子、坑槽或T型筋减少摩擦并加强抗弯力,塑料、橡胶或石墨触点滑块和扇叶粘附润滑剂或石墨粉滑触扇叶减少摩擦,条形触点滑块外凸或内凸触滑并清洁扇叶;扇叶连接防脱保险,多级卡扣防脱,保险索防脱,脱扣自动关闭电源,加大扇叶伸缩范围无须加大灯饰直径,灵活搭配灯饰。
