Claims19
A ball lock assembly for use with an injection device comprising:
- ball lock frame;
- a ball lock core housed within the ball lock frame;
- a retention pin;
- and
- a fastener configured to restrict a lateral movement of the retention pin;
- wherein the ball lock core comprises a longitudinal opening, wherein a portion of the retention pin is positioned within the longitudinal opening;
- wherein the retention pin is anchored to the ball lock frame at two or more points;
- wherein the retention pin and longitudinal opening are configured to allow the proximal and distal movement of the ball lock core and to limit the proximal movement of the ball lock core to a set endpoint;
- wherein the ball lock assembly is in a locked position when the ball lock core is in a most proximal position of the ball lock core;
- and
- wherein the ball lock core is at the most proximal position of the ball lock core when the retention pin abuts a distal end of the longitudinal opening.
