Abstract
The utility model discloses a close-fold tent frame which can automatically unfold and comprises a top connecting part, a plurality of support bar units and elastic units which have the equal amount with the support bar units, and have rebound force caused by bending when being closed to fold. Each support bar unit forms a relative rotation movement relation with the top connecting part. A first end of each elastic unit is connected with the support bar unit, and a second end is connected with the top connecting part. The technical proposal of the close-fold tent frame has the beneficial effects that: firstly, only one layer of support bar unit structure is arranged at the top of the tent frame, so the amount of the bar member is small, the manufacture cost is low, the inner height is high and the inner space is large after a tent cloth is connected; secondly, the elastic units are arranged in the tent frame, and are bended storing elastic energy when being closed to fold. The elastic units can rebound the elastic units, automatically support the support bar units, and unfold the tent frame after being unfolded to release the elastic energy, therefore, the close-fold tent frame can automatically unfold.
