Abstract
The invention discloses shock absorbing anti-fallout equipment for a sucker rod. The top joint of the shock absorbing anti-fallout equipment is fixedly arranged at the upper end of a central rod by virtue of a first screw; the lower end of the central rod is inserted into an outer barrel and is fixed; a plurality of elastic rings are arranged in the outer barrel; a spacer bush is arranged in the middle section of the outer barrel; the lower section of the outer barrel is sleeved with a pressure barrel; a first seal ring is arranged between the outer barrel and the pressure barrel; a connecting rod arranged in the pressure barrel in a penetrating manner; a second seal ring and a third seal ring are arranged between the connecting rod and the pressure cylinder; the joint is inserted at the lower end of the pressure cylinder; the lower joint is arranged in the joint in a penetrating manner; steel balls are placed in a first arc-shaped groove of the lower joint and a second arc-shaped groove of the joint; a steel ball putting screw hole is formed at the connector relative to the second arc-shaped groove to block a fifth screw, and the lower joint can freely rotate in the connector without falling out. Vibration of the sucker rod is alleviated as the elastic rings are arranged in the outer barrel. The lower joint is connected with the connector by virtue of three steel balls, so that the sucker rod connected with the lower joint can freely rotate without being falling out of the connector.
