The invention belongs to the technical field of escalators, and especially relates to a safety device of an escalator. The safety device comprises a handrail belt; a safety belt is fixedly connected to the upper end surface of the handrail belt; a plurality of limiting grooves which are uniformly distributed are formed in the upper end surface of the safety belt; a fixation block is clamped on theouter side of the safety belt; a fixing rod penetrates through the upper end surface of the fixation block; limiting blocks matched with the limiting grooves are fixedly connected to the lower end ofthe fixing rod; a first hollow box is fixedly connected to the right side wall of the fixation block; a spring is connected to the right end face of the first hollow box in a penetrating mode; a second hollow box is connected to the other end of the spring in a penetrating mode; a slipknot hanging ring is fixedly connected to the right end face of the second hollow box; the slipknot hanging ringis opened and installed on the outer side of a handle of a luggage case, and then the connecting groove is connected with the safety belt in a clamped mode, and the fixing rod is pressed downwards todrive the limiting blocks to enter the limiting grooves, so that the installation stability of the fixing block is enhanced; and the luggage case can be pulled back through the spring when being impacted by external force and falls off, so that other people are prevented from being hurt when the case rolls down.
本发明属于自动扶梯技术领域,尤其为自动扶梯的安全装置,包括扶手带,扶手带的上端面固定连接有安全带,安全带的上端面开设有多个均匀分布的限位槽,安全带的外侧卡接有固定块,固定块的上端面贯穿连接有固定杆,固定杆的下端固定连接有与限位槽相匹配的限位块,固定块的右侧壁固定连接有第一空心盒,第一空心盒的右端面贯穿连接有弹簧,弹簧的另一端贯穿连接有第二空心盒,第二空心盒的右端面固定连接有活扣挂环;将活扣挂环打开安装在行李箱把手外侧,然后使连接槽与安全带卡接,再将固定杆向下按压带动限位块进入限位槽内,进而增强固定块安装的稳定性,当行李箱受外力撞击滑落时可通过弹簧将其拽回,从而避免箱子滚落致使他人受伤。
