The invention discloses a linkage device for an elevator with underneath safety tongs. The linkage device comprises a transmission rod, first safety tongs, second safety tongs and a lifting plate. The linkage device has the beneficial effects that the linkage device is directly installed on a bracket at the bottom of the lift car through a fixing support, the structure is simple, the manufacturing cost is low, installation is convenient and fast, and adjustment is easy; and the linkage device can be adapted to elevator with lift car with different widths, when the length of the transmission rod needs to be adjusted, a lifting block is pulled upwards to drive an inserting rod to be separated from an inserting groove, then the transmission rod is manually pulled to be lengthened, when the required length is reached, the lifting block is loosened, the inserting rod can be inserted into different inserting holes again under the reset function of a spring, and the length of the transmission rod can be conveniently adjusted according to the width of the lift car, so that the linkage device can adapt to elevators with different car body widths.

    本发明公开了一种用于安全钳下置电梯的联动装置,包括传动杆、安全钳一、安全钳二和提拉板。本发明的有益效果是:该联动装置通过固定支架直接安装在所述轿厢底部的托架上,结构简单,制作成本低,安装便捷,易于调节;可以适应不同宽度轿厢的电梯,当需要对传动杆的长度进行调解时,通过向上拉动提拉块,使得提拉块带动插杆从插槽内脱离,然后人为抽拉传动杆,使得传动杆的长度伸长,当达到所需要的长度时,松开提拉块,使得插杆在弹簧的复位作用下再次插入不同的插孔,便于根据轿厢的宽度来调节传动杆的长度,从而可以适应不同箱体宽度的电梯。
