Lattice type steel structure supporting column

Abstract

The lattice type steel structure supporting column comprises a first supporting column body, a second supporting column body and locking pieces, the second supporting column body is movably installed at the upper end of the first supporting column body, and the locking pieces are movably arranged on one side of the upper end of the first supporting column body in a sleeved mode and located in front of and behind the first supporting column body. Mounting seats are fixedly mounted at the bottom of the first supporting column and the top of the second supporting column. According to the lattice type steel structure supporting column, when the lattice type steel structure supporting column is not used, the lock sleeve of the lock piece is rotated, at the moment, the lock sleeve continuously rotates and descends until the inserting rod of the second supporting column retreats from the lock sleeve of the lock piece, the first supporting column and the second supporting column can be folded together by turning over the second supporting column, and therefore the lattice type steel structure supporting column is formed. In this way, the overall height of the lattice type steel structure supporting column can be reduced, and due to the fact that the length of the lattice type steel structure supporting column is reduced, the lattice type steel structure supporting column is convenient to carry and does not need a long space during storage.
