Secure moving stage
The invention discloses a secure moving stage. The secure moving stage comprises a foldable stage plate and an extendable frame hinged to the stage plate, wherein the extendable frame comprises a plurality of vertical supporting rods and a plurality of obliquely-arranged extendable rods, a sliding groove for accommodating a hinge shaft capable of moving up and down is formed in the top end of eachsupporting rod, supporting legs are fixedly connected to the bottom end of the extendable frame in a staggered mode, moving blocks with inclined teeth are arranged on the bottom end surface of the extendable frame, a foldable screw rod is arranged at the moving blocks in a meshing mode, screw rod extendable sleeves slidably connected with the supporting rods and sliding wheel extendable grooves for containing sliding wheels are arranged in the supporting legs, and external threads threaded meshing with the screw rod are arranged on the screw rod extendable sleeves. The secure moving stage hasthe following beneficial effects that (1) the stability is greatly improved when the stage is unfolded; (2) the stage is automatically folded, so that the convenience and the fastness are completelyachieved; and (3) the structure is stable, firm and durable.
本发明公开了一种安全移动舞台，包括可折叠的舞台板和与舞台板铰接的伸缩架，伸缩架包括若干竖直的支撑杆和若干斜置的伸缩杆，每一根支撑杆顶端设有容纳可上下移动的铰接轴的滑槽，伸缩架底端交错固接有支撑脚和底端面设有斜齿的移块，移块啮合有可折叠的丝杆，支撑脚内设有与支撑杆滑动连接的丝杆伸缩套筒和用于容纳滑轮的滑轮伸缩槽，丝杆伸缩套筒上设有与丝杆螺纹啮合的外螺纹。本发明具有如下有益效果：（1）大大提高了舞台展开时的稳定性；（2）舞台自动折叠，十分方便快捷；（3）结构稳定牢固，耐用。
