Abstract

A tray for heat treatment furnace including a tray base which comprises a plate and a lattice part being fixed on the plate, said lattice part having a plurality of cylindrical reinforcements formed at cross portions thereof; a fixing device having a plurality of paired barrels being connected to each other by a plurality of connecting members, each of said paired barrels being provided with a plurality of cutting grooves on an upper surface thereof, one of the connecting members having a pair of coupling jaws for engagement with a portion of the lattice part; a plurality of spacers each being engageable with one of a respective said plurality of cutting grooves.

Claims

1. A tray for a heat treatment furnace, comprising:

a tray base which comprises a plate and a lattice part being fixed on the plate, said lattice part having a plurality of cylindrical reinforcements formed at cross portions thereof;

a fixing device having a plurality of paired barrels being connected to each other by a plurality of connecting members, each of said paired barrels being provided with a plurality of cutting grooves on an upper surface thereof, one of the connecting members having a pair of coupling jaws extending from a bottom surface thereof for engagement with a portion of the lattice part;

a plurality of spacers each being engageable with one of a respective said plurality of cutting grooves.

2. A tray for a heat treatment furnace according to claim 1, wherein each spacer includes a disk-shaped base plate having a recess therein, a plurality of L-shaped supporting frames perpendicularly and radially fixed to the upper surface of the disk-shaped base plate, a male connector being supported by the supporting frames at a center portion thereof, and a female connector being positioned under the male connector and being supported by the supporting frames.

3. A tray for a heat treatment furnace according to claim 2, wherein the supporting frame is provided with a protrusion at a lower portion thereof, the protrusion being inserted into the cutting groove of the fixing device, and

a projecting jaw being located at an angle part above the base plate.
