Structurally reinforced tent frame and central reinforcing structure thereof

Abstract

A structurally reinforced tent frame includes standing poles that each have a connecting base and a slidable base are disposed thereon. A first tarpaulin supporting pole has one end hinged on the connecting base and another end hinged with a top plate. An auxiliary supporting pole has one end hinged on the first tarpaulin supporting pole and another end hinged with the slidable base. A hinged crossbeam is disposed between adjacent standing poles and has ends connected with the connecting bases and the slidable bases. A second tarpaulin supporting pole has one end hinged with a hinge point of the hinged crossbeam and another end hinged with the top plate. Four second tarpaulin supporting poles and two first tarpaulin supporting poles are connected to supporting poles. Other ends of the supporting poles are hinged with a lower plate. A retractable position-limiting pole is disposed between the lower plate and the top plate.
