Patent ID: 8302266

Claim:
A resilient rotation buckle comprising: a belt coupling structure having a hollow frame and an accommodation channel which is in communication with said hollow frame via a through hole, said hollow frame having an end provided at a bottom thereof with a belt clamping structure; a decoration plate fitted in said hollow frame; a rotation shaft having a first end fixed to said decoration plate and a second end extending through said through hole into said accommodation channel, said rotation shaft having two opposite arc side surfaces and two opposite planar side surfaces; and a pair of curved spring plates fitted in said accommodation channel and being in tight engagement with said planar side surfaces of said rotation shaft; wherein when said decoration plate is in a parallel condition, said curved spring plates are in tight engagement with said planar surfaces of said rotation shaft thereby causing said curved spring plates to show maximum curvature inside said accommodation channel and smallest spring forces; when said decoration plate is gradually rotated, said rotation shaft changes angular position thus making said curved spring plates that are in contact with said rotation shaft to increase spring forces thereof; and when said decoration plate is rotated by 130 degrees, said curved spring plates will drive rotation of said rotation shaft hence causing automatic rotation of said decoration plate back to said parallel condition and therefore completing automatic positioning after said rotation.
