Abstract

A device rack, which includes a base frame having an upright annular flange and an upright peripheral wall around the upright annular flange, a rotary disk ratably coupled to the upright annular flange inside the base frame and partially peripherally projecting out of the base frame for rotation by hand, the rotary disk having a spiral groove at a front side, two angled clamping members coupled to the rotary disk and moved relative to each other upon a rotary motion of the rotary disk, the clamping members each having a bottom rod inserted into the spiral groove at the rotary disk, and a platform covered on the base frame over the rotary disk to hold the rotary disk and the clamping members in place.

Claims

1. A device rack comprising:

a base frame, said base frame comprising an upright peripheral wall, and an upright annular flange raised from an inside wall thereof and surrounded by said upright peripheral wall;

a rotary disk mounted on said upright annular flange within said base frame, said rotary disk comprising a bottom coupling groove formed on a back side wall thereof and coupled to said upright annular flange inside said base frame for allowing said rotary disk to be rotated on said upright annular flange, upright spiral walls raised from a front side wall thereof and defining a spiral sliding groove;

two symmetrical clamping members coupled to said rotary disk and moved relative to each other for clamping an object put in therebetween, said clamping members each comprising a horizontal base and a vertical plate connected at right angles, said horizontal base comprising a plurality of elongated notches and fingers alternatively arranged in parallel at a front side thereof remote from said vertical plate, a plurality of extension tips respectively and forwardly extended from said fingers, and a bottom rod perpendicularly raised from one of said fingers at a bottom side and inserted into the spiral sliding groove at said rotary disk, said extension tips having a size fitting said elongated notches; and

a platform covered on said base frame;

wherein rotating said rotary disk causes said clamping members to be moved relative to each other.

2. The device rack of claim 1 wherein said upright peripheral wall of said base frame comprises a curved wall portion curved inwards, and a top notch at said curved wall portion through which a part of the periphery of said rotary disk projects outside said base frame;

said platform has a curved peripheral wall fitting the curved wall portion at the upright peripheral wall of said base frame.

3. The device rack of claim 1 wherein said rotary disk comprises a toothed peripheral wall.

4. The device rack of claim 1 wherein said clamping members each further comprise a clamping head mounted on the respective vertical plate, and the vertical plate of each of said clamping members comprises a front side wall, a recessed portion at said front side wall, which receives the respective clamping head, and a positioning groove in said recessed portion to which the respective clamping head is fastened.

5. The device rack of claim 1 wherein said base frame comprises mounting means for securing to an external support.

6. The device rack of claim 1 wherein said base frame comprises a plurality of stub mounting barrels, and said platform comprises a plurality of bottom mounting holes respectively fastened to the stub mounting barrels at said base frame by fastening elements.

7. The device rack of claim 1 wherein the horizontal base of each of said clamping members comprises a plurality of top sliding ribs extending in same direction of said fingers, and said platform comprises a plurality of bottom sliding grooves respectively coupled to the sliding ribs at said clamping members.
