More Information
Summary:The utility model provides a bidirectional telescoping mechanism, which adopts two lead screws with opposite rotation directions, one lead screw and a nut thereof are arranged in an internal central hole of the other lead screw, and then bidirectional telescoping is realized by adopting a transmission principle which is the same as that of a traditional coaxial double-helix spiral transmission mechanism. Therefore, on the premise that the stretching stroke requirement is met, the short contraction length is achieved. The bidirectional telescopic mechanism comprises a rack, two telescopic cylinders, an inner lead screw, an outer lead screw, an inner lead screw nut, an outer lead screw nut, a gear motor, a gear A and a gear B, the inner lead screw, the inner lead screw nut and the telescopic cylinder B are installed in an inner center hole of the outer lead screw, after the telescopic cylinder B is contracted, except for the guiding part, the other length is hidden in the outer lead screw, the length of the who
