The invention discloses a ventilation lock bottom structure for eliminating the weld porosity of annular element electron beams. On a lock bottom matching surface of an annular element, a ventilation groove (7) is processed in the axial direction, and is uniformly distribution along a circumference matching surface; the length L of the ventilation groove (7) is identical to the width B of an annular lug boss (2); the width and the depth dimensions of the ventilation groove (7) are designed according to the welding thickness; the peripheral space of the ventilation groove (7) is designed according to the annular element diameter. The lock bottom structure with the ventilation groove has the advantages that the generation of the weld porosity defect can be reduced and eliminated; the welding process quality is improved; the anti-fatigue performance of a connector is improved, so that the reliability and the stability of the welding structure are enhanced.
