Actuator and exercise equipment using same

An exercise equipment comprising:

• a post which is a main body of the exercise equipment;
• a shoulder installed on an upper side of the post and configured to rotate in left and right directions;
• an arm combined with the shoulder and configured to rotate in up and down directions;
• a hand combined with one terminal of the arm and configured to rotate by using the arm as an axis;
• a handle located on one terminal side of the hand;
• a force control actuator configured to output a force corresponding to a weight set by a user;
• and
• a wire configured to pass via plural sheaves included in the hand, the shoulder and the post and deliver a force generated by pulling of the handle, one terminal of the wire being connected to the handle,
• wherein the post includes a fixing sheave block fixed in the post, an upper part moving sheave block located below the fixing sheave block and a lower part moving sheave connected to a lower part of the upper part moving sheave block,
• wherein the wire passes via the fixing sheave block by one or more times and passes via the upper part moving sheave block by one or more times, and a belt of the force control actuator passes via the lower part moving sheave,
• wherein
• the arm and the shoulder are combined by a first pin having a hollow shaft and the arm rotates in up and down directions on the first pin,
• an up angle or a down angle of the arm is fixed by inserting a clamp into fixing holes formed respectively in a specific angle space on the arm and the shoulder,
• the shoulder is combined with the post by using a second pin having a hollow shaft and rotates in left and right directions, and
• a left angle or a right angle of the shoulder is fixed by inserting a clamp into fixing holes formed respectively in a specific angle space on the shoulder and an upper side of the post,
• wherein the shoulder includes a first fixing sheave, a second fixing sheave and a third fixing sheave, and
• wherein
• the first fixing sheave is inserted by the first pin,
• a radius of the first fixing sheave is matched with an offset of a wire passing vertically from a rotation axis of the arm and the shoulder,
• the wire passes, from the post, the first fixing sheave via a lower part of the second fixing sheave after passing via an upper part of the third fixing sheave through the hollow shaft of the second pin, and
• a path of the wire wound on the upper part of the third fixing sheave through the hollow shaft of the second pin matches with a rotation axis of the shoulder.
