Abstract
The utility model discloses a drill rod seat which comprises a sealed cabinet. A nitrogen chamber is arranged inside the cabinet, a through hole is formed in the right side wall of the cabinet, the outer port of the through hole is provided with a barrel-shaped connecting seat integrated with the cabinet, an arced sealing groove is arranged in the inside wall, on the outer periphery of a joint of the connecting seat and the cabinet, of the cabinet, mounting grooves of O-shaped rubber rings are distributed at intervals in the outer wall, close to the position of the sealing groove, of the connecting seat, an annular platform is arranged on the outer wall, to the right of the mounting groove, of the connecting seat, and inner threads are arranged in the through hole and the inner hole of the connecting seat. The drill rod seat is novel in structural design; through the design of the connecting seat at the reasonable position of the cabinet and structures like the sealing groove, the mounting groove and the annular platform which are arranged on the connecting seat and outside the cabinet, sealing property of the drill rod seat after mounted is sufficiently improved, and high practicability can be achieved.
