The invention provides an elevator door contact type protection device which is used for being installed at a gap between an elevator door and a door pocket and comprises a shell provided with a hollow closed cavity, a fluid substance arranged in the closed cavity and a pressure detection device used for detecting the pressure change condition of the fluid substance in the closed cavity. The external elevator door can act according to detection information of the pressure detection device. According to the scheme, through the arrangement, whether foreign objects approach the gap between the elevator door and the door pocket or not can be detected in real time, corresponding actions can be made in time according to the current situation, safety accidents are avoided, and the safety coefficient of elevator use is improved.

    本发明提供一种电梯门接触式保护装置,用于安装于电梯门和门套之间的缝隙处,包括:设有中空的封闭腔体的壳体、设置于封闭腔体内的流体物质以及用于检测封闭腔体内流体物质的压力变化情况的压力检测装置,外部电梯门能够根据压力检测装置的检测信息进行动作。本方案通过上述设置,能够实时检测电梯门和门套之间的缝隙处是否有外物靠近,并且能够根据当下的情况及时作出对应动作,避免发生安全事故,提高电梯使用的安全系数。
