Abstract
The utility model discloses a bar-shaped no-excitation tapping switch operating apparatus. The apparatus comprises an operating rod shaft (1), a flange (2), a positioning seat (3), a fastening nut (4), sealing rings (5) and a rotary handwheel (6). The apparatus is characterized in that the positioning seat (3) and the base plate end face of the rotary handwheel (6) are correspondingly provided with gear positioning bosses (31) and grooves (61); the bosses and the grooves cooperate with one another; a groove (63) is further arranged on the side end of a base plate (60) of the rotary handwheel (6); and an upper gland (7) is arranged on the upper end of the operating rod shaft (1) in a cooperative threaded-connection way. After a gear shift process, the upper gland (7) is screwed to make the rotary handwheel (6) compressed. The rotary handwheel is further locked. The bar-shaped no-excitation tapping switch operating apparatus with a simple structure is convenient to use and operate and achieves gear shift accuracy and positioning accuracy. The apparatus which cannot be rotated at will is safe and reliable to use.
