一种带防夹手结构的电梯层门门刀

Abstract

本实用新型涉及电梯层门门刀技术领域，公开了一种带防夹手结构的电梯层门门刀，包括门刀本体，所述门刀本体内壁两侧均滑动连接有拉杆，所述拉杆内壁均通过卡扣组件连接有连接框，以用于缓冲机构的拆装，所述连接框内壁均通过缓冲组件连接有橡胶垫，以用于减少门刀本体对手臂的伤害，所述橡胶垫外壁两侧均开设有凹槽，所述橡胶垫外壁均滑动连接在连接框内壁。本实用新型中，通过在门刀本体之间设置有缓冲机构，能从结构层面解决传统门刀刚性夹持易伤手的问题，可缓冲门关闭时刀臂对异物的夹持力，避免手部伸入间隙后先受挤压，还能弥补光幕等现有防夹技术的响应延迟、检测盲区及传感器失效风险，提升电梯运行安全性与可靠性。
