The invention belongs to the technical field of elevator safety tongs, and particularly relates to a progressive safety tongs protection switch device structure for an elevator, which comprises a frame 1 and a guide rail 2, the interior of the frame 1 is fixedly connected with a supporting plate 4; a U-shaped plate spring 5 is arranged above the supporting plate 4; sliding blocks 6 are symmetrically arranged on the inner side of the U-shaped plate spring 5. The two sides of the sliding block 6 are fixedly connected with a pair of guide blocking pieces 7. A reinforcing plate 8 is fixedly connected between the bottoms of the pair of guide separation blades 7; a wedge block 9 is connected to the inclined surface of the sliding block 6 in a sliding manner; the pair of guide blocking pieces 7 on the two sides of the sliding block 6 are arranged to be of an integral structure, so that the guide blocking pieces 7 and the sliding block 6 are more convenient and faster to install, the situation that the pair of guide blocking pieces 7 are installed in a misplaced mode is avoided, and therefore the good limiting effect of the guide blocking pieces 7 on the wedge block 9 is guaranteed; the reinforcing plate 8 can further improve the connecting strength between the pair of guide blocking pieces 7, and the guide blocking pieces 7 are prevented from being twisted and deformed.

    本发明属于电梯安全钳技术领域,具体的说是一种电梯用渐进式安全钳保护开关装置结构,包括框架1和导轨2;所述框架1内部固定连接有支撑板4;所述支撑板4上方设置有U形板簧5;所述U形板簧5内侧对称设置有滑块6;所述滑块6两侧固定连接有一对导向挡片7;一对所述导向挡片7底部之间固定连接有加强板8;所述滑块6的斜面上滑动连接有楔块9;通过将滑块6两侧的一对导向挡片7设置为整体结构,使得导向挡片7与滑块6之间安装时更加方便快捷,并避免出现一对导向挡片7安装错位的情况,从而保证导向挡片7对楔块9良好的限位作用,加强板8可以进一步提高一对导向挡片7之间的连接强度,防止导向挡片7扭曲变形。
