Tent frame

Abstract

Disclosed is a tent frame. The tent frame includes a tent roof fixing block, where an outer side of the tent roof fixing block is movably connected to a plurality of first connection rods through rotary shafts, and one ends of the plurality of first connection rods are movably connected to connectors through rotary shafts; one sides of the plurality of connectors are movably connected to second connection rods through rotary shafts, and one sides of the plurality of second connection rods are provided with supporting assemblies; a bottom of the tent roof fixing block is provided with an unfolding mechanism. The disclosure has the beneficial effects as follows: supporting structures are evenly stressed, and the tent frame is stabler and does not deviate after being unfolded. Accordingly, the tent frame is convenient to use and simpler to fold.
