Abstract
The utility model discloses an inner coiling apparatus of a rotary mechanism and belongs to the field of signal transmission. The inner coiling apparatus comprises a fixation system and a rotary system which are connected through a bearing and a flat cable. The rotary system rotates around the fixation system so that when the motion wire gripper in the rotary system rotates, a corresponding movable pulley block rotates, at the moment, the flat cable disposed on a pulley block performs corresponding rotation along the movable pulley block to ensure the tightness on the movable pulley block so as to ensure that the flat cable can always be attached to an inner coiling drum, the movable pulley block and an outer coiling drum when the rotary system rotates and reverses at any places within a range of 0 to 360 degrees, and "too loose to fold" or "too tensed to break" phenomena of the cable can be prevented. The inner coiling apparatus of the rotary mechanism has the advantages of simple structure, lowered manufacturing cost, reliable operation, and ensured stable transmission of cable signals, thereby being applied to a 0-360-degeree rotational radar antenna base or some small-and-medium power rotary mechanisms.
