The invention relates to a rollover handrail structure, which comprises a base, a handrail body, a handrail body and a handrail body, wherein two bases are arranged at the front end and the rear end of the base; the armrest cover is positioned above the base, can turn over around the left side or the right side of the base, and comprises an armrest cover lower cover, an armrest cover shaft body and an armrest cover upper cover; the two sets of pin shaft assemblies are arranged at the front end and the rear end of the lower armrest cover, each set of pin shaft assembly comprises two sets of pin shaft units located on the left side and the right side of the armrest cover shaft body, and each set of pin shaft unit comprises a pin shaft base and a locking pin shaft which can move in the front-back direction and lock or loosen the armrest cover shaft body and the base; the two starting assemblies are located on the left side and the right side of the armrest cover lower cover and symmetrically distributed, and each starting assembly comprises two moving blocks capable of synchronously moving in the left-right direction; and the four groups of fixed pulley assemblies are arranged between each group of pin shaft unit and the moving block and are in transmission connection with the pin shaft unit and the moving block. Compared with the prior art, the device is simple in structure and convenient to operate, and the risks of overturning critical point clamping stagnation and abnormal sound are greatly reduced.

    本发明涉及一种侧翻扶手结构,包括:底座,其前后两端设置有两个基座;位于底座上方、并能绕基座的左侧或右侧翻转的扶手盖,包括扶手盖下盖、扶手盖轴体、扶手盖上盖;设置在扶手盖下盖前后两端的两组销轴组件,每组销轴组件包括位于扶手盖轴体左右两侧的两组销轴单元,每组销轴单元包括销轴座、和能沿前后向移动并锁住或松开扶手盖轴体和基座的锁定销轴;位于扶手盖下盖左右两侧且对称分布的两组启动组件,每组启动组件包括能同步沿左右向移动的两个移动块;以及设置在每组销轴单元和移动块之间并使其传动连接的四组定滑轮组件。与现有技术相比,本发明结构简单,操作便捷,大大降低了翻转临界点卡滞、异响的风险。
