The invention relates to the technical field of elevators, and discloses an elevator car safety anti-pinch device which comprises a car body, a guide strip installed on the front side of the car body and elevator doors sliding in the guide strip, an anti-pinch assembly I is arranged between the elevator doors on the two sides, and the anti-pinch assembly I comprises a metal frame layer fixed in the car body; the telescopic plate is arranged in the metal frame layer in a sliding manner; and one end of the telescopic rod body is hinged to the outer side of the telescopic plate, the other end of the telescopic rod body is hinged to the elevator door, and the telescopic rod body drives the telescopic plate to move inwards and outwards in the opening and closing process of the elevator. Through the buffering effect of the rubber shaft, the rubber shaft is in contact with a body part for extrusion in advance, the rubber shaft can extrude a supporting spring inwards, the rubber shaft extrudes a human body, the body part can be rapidly pulled out, clamping is avoided, reaction time is provided, and sliding friction is changed into rolling friction; the human body injury is avoided.
本发明涉及电梯技术领域,且公开了一种电梯轿厢安全防夹设备,包括轿厢本体、安装在轿厢本体前侧的引导条,以及滑动在引导条内的电梯门,两侧所述电梯门之间设有防夹组件一,所述防夹组件一包括:金属框层,其固定在轿厢本体内部;伸缩板,其滑动设置在金属框层的内部;伸缩杆体,其一端铰接在伸缩板的外侧,且伸缩杆体另一端与电梯门呈铰接设置,在电梯开合过程中驱动伸缩板向内外方向的移动。本发明通过设置橡胶轴的缓冲作用,事先由橡胶轴与身体部位接触挤压,由于橡胶轴能向内进行挤压支撑弹簧,橡胶轴挤压人体,能迅速的将身体部位进行抽出,避免被夹持住,提供一个反应的时间,以及使滑动摩擦为滚动摩擦,避免人体的受伤。
