Patent ID: 7478971

Claim:
A shelf connector for mounting a shelf on a supporting rod, comprising: a sliding sleeve ( 1 ) mounted on a supporting rod, the sliding sleeve formed with a locking body ( 12 ), the locking body ( 12 ) provided with an open groove ( 11 ) along the axial direction of the sliding sleeve ( 1 ), the locking body ( 12 ) provided on both sides of the open groove ( 11 ) with a clasping portion ( 12 a / 12 c ) projecting outwardly from the sliding sleeve, at least one recessed introducing section ( 12 b ) being provided on the sliding sleeve ( 1 ) above the clasping portions ( 12 a / 12 c ); and a locking sleeve ( 2 ) connected to a shelf, the locking sleeve having a single locking groove ( 21 ), the locking sleeve being received on the sliding sleeve within the introducing section such that, a width of the open groove ( 11 ) is compressively reduced by insertion of the clasping portions ( 12 a / 12 c ) into the locking groove ( 21 ), wherein a width of the locking groove ( 21 ) is slightly smaller than a width of the clasping portions ( 12 a / 12 c ), the sliding sleeve ( 1 ) comprising an open structure for directly clasping on the supporting rod ( 3 ) an inner wall of the sliding sleeve ( 1 ) opposite to the open groove ( 11 ) comprising an axially extending hinge ( 13 ) functioning as a shaft-and-pin mechanism for pivotally opening and closing the sliding sleeve to receive the supporting rod, the inner wall of the sliding sleeve ( 1 ) adjacent to the hinge ( 13 ) comprising an integrally formed axially extending rib ( 15 ) which frictionally engages the supporting rod for positioning the opening and closing actions of the hinge ( 13 ) on the supporting rod.
