Anti-gravity backpack

Abstract

The present invention discloses an anti-gravity backpack, which comprises a backpack body and two shoulder straps. A supporting plate is provided on a back of the backpack body, and a pressure reducing plate is provided on a back of the supporting plate. A first elastic band and a length fixing band are provided between the pressure reducing plate and the supporting plate. The existence of the pressure reducing plate, the first elastic band and the length fixing band causes the backpack to bounce up and down to act as a buffer, which not only relieves the pressure on the wearer's shoulders but also saves the wearer's energy with the resilience produced by the elastic band, thus helping slow down the wearer's rate of muscle fatigue and make the wearer feel less burden on the body.
