Abstract
The present invention is directed to a rod string with a plurality of rod sections and a method for making up and breaking out the rod sections. The rod sections have corresponding pin and box ends, each having grooves and lands and an ungrooved portion. The rod sections can be connected by inserting the pin end into a box end and turning less than a full turn. A lock engagement mechanism having a first end and a second end is provided inside the rod sections and locks when the pin end is rotated into place. The lock engagement mechanism has a rotation stop which protrudes proximate the first end to prevent relative rotation of two rod sections until a key manipulates the lock engagement mechanism to retract the rotation stop.
