The purpose of this invention is to provide a flexible baseboard, it solves the problem that the prior art can not meet the security needs of the shallow pit defects, including a fixed base plate, the movable plate and the movable connecting rod, which is characterized in that the upper part of the fixed substrate and the movable plate are provided with horizontal guide groove horizontal base rod, a vertical guide groove is arranged in the middle part of the fixed base plate, the connecting rod is hinged at the level of the base rod of the movable plate on the central pin shaft, a vertical reciprocating movement along the guide groove of the fixed base plate, between the fixed base plate and a movable plate or adjacent the movable plate through the the level of the base pole horizontal guide slot and arranged on the end part of the connecting pin hinged together, and the end part of the connecting pin level guide groove reciprocating movement along the horizontal pole, in the A baseboard lock is hinged on the horizontal base rod of the fixed baseplate, and the locking pin matched with the lock hook of the baseboard lock is fixed on the horizontal base rod of the movable plate. The utility model has the advantages of simple structure, easy operation and safe and reliable operation.
【技术实现步骤摘要】
本专利技术涉及一种电梯用的护脚板,特别是一种适用于浅底坑电梯的伸缩护脚板。
技术介绍
目前,电梯用的护脚板安装在轿厢地坎下面,不可伸缩,此种结构设计简单,可适 用于大多数电梯。但当底坑深度较浅时,此种设计在电梯运行至最底层时会刮碰底坑地面, 使护脚板损坏;同时对于底坑内的专业维修人员来说也可能造成伤害,因而传统护脚板不 能适应浅底坑的安全需要。在专利号为CN200520051796. X的“垂直升降电梯轿厢电动护脚板装置”中,公开 了一种电动护脚板的设计,其采用手动控制给小电机给电,小电机转动,通过转向装置使主 动轴做轴向运动带动连杆组件动作,连杆组件通过销在侧盖板的滑槽内滑动,促使侧盖板 与其上的轴一起转动。当旋转到和轿厢底平面垂直位置时,触发到位开关,小电机停止运 转,护脚板打开,实现保护的方式。但结构过于复杂,不便于加工,而且制造成本也很高;另 外在专利申请号为200710068463. 1的“伸缩式轿厢护脚板”中,所提及的伸缩式护脚板采 用护脚板由上片和下片构成,在上片或者在下片的两侧,各设导向槽,使下片的上部分或者 是上片的下部插入导向槽内并使下片能 ...
