Zusammenfassung: | A steel pipe pole capable of realizing rapid butt joint relates to the technical field of butt joint of steel pipe poles, and is characterized in that a second steel pipe pole is lifted, a conical groove II in the second steel pipe pole is pressed into a conical groove I, and a conical block on the conical groove I is in butt joint with a conical groove in the conical groove II, so that the second steel pipe pole is displaced; in the process that a second conical groove is pressed in a first conical groove, the first conical groove drives an annular sliding block to move along an annular groove, so that the annular sliding block extrudes a spring, and then the second conical groove is pressed on the first conical groove through the elastic force of the spring for damping; the conical groove II and the conical groove I are prevented from being damaged, and the stud extends through the threaded hole; according to the utility model, the upper and lower steel pipe poles are butted and aligned, so that the bolts c |
