ABSTRACT:
Disclosed herein is a tent frame. The tent frame comprises a hollow supporting body having a bottom-opened cylinder extending downward from an inner top surface thereof, a columnar slider axially coupled to the bottom-opened cylinder in a vertically movable manner and formed at an outer circumference thereof with racks, first elastic means coupled at a first end thereof to the supporting body and at a second end thereof to the columnar slider so as to provide the columnar slider with a vertical movement force, and main poles rotatably coupled around the supporting body so as to be unfolded through rotation. The main poles are formed at their first ends with pinions to engage with the racks of the columnar slider. With such a simplified structure, the tent frame of the present invention can be rapidly and easily folded or unfolded, and the completely unfolded state of the frame can be simply maintained.
