A T-shaped pressure groove 27 is provided on the outer side of the top surface of the T-shaped groove 26. A T-shaped pressure plate 28 matching the T-shaped pressure groove 27 is connected to the top surface of the T-shaped block 25, and the top surface of the T-shaped pressure plate 28 is flush with the top surface of the support beam 4. A fixing through hole is provided at the center of the fixing block 24, and a fixing bolt 29 is provided in the fixing through hole. The screw end of the fixing bolt 29 is fixedly connected to the upper support seat 22 after passing through the fixing through hole, and the top surface of the fixing bolt 29 is flush with the top surface of the support beam 4; a plurality of convex-shaped slide grooves 31 parallel to the width direction of the shelf board 3 are provided on the top surface of the shelf board 3, and a No. 1 waist-shaped air vent 32 is provided on the shelf board 3 below the convex-shaped slide groove 31, and the No. 1 waist-shaped air vent 32 runs through from the front side of the shelf board 3 to the rear side of the shelf board 3, and a No. 2 waist-shaped air vent 33 is provided between two adjacent No. 1 waist-shaped air vents 32, and the No. 2 waist-shaped air vent 33 runs through from the front side of the shelf board 3 to the rear side of the shelf board 3, and a plurality of horizontal connecting through holes 34 are provided on one side of the shelf board 3, and the connecting through holes 34 run through from the left side of the shelf board 3 to the right side of the shelf board 3, and the No. 1 waist-shaped air vent 32 and the No. 2 waist-shaped air vent 33 are both connected to the connecting through holes 34.

[0025] The cross section of the first waist-shaped vent hole 32 is a horizontal waist-shaped hole, and the cross section of the second waist-shaped vent hole 33 is a vertical waist-shaped hole.

[0026] An ejector pin 5 is slidably connected in the convex-shaped slide groove 31. The ejector pin 5 includes a supporting portion 51 with a triangular cross-section and a sliding portion 52 with a convex-shaped cross-section. The top surface of the sliding portion 52 is fixedly connected to the supporting portion 51, and the sliding portion 52 is slidably connected to the convex-shaped slide groove 31. The top end of the ejector pin 5 fits against the bottom surface of the ceramic to be fired. The supporting portion 51 of the ejector pin 4 has a triangular cross-section, which can reduce the contact area with the bottom surface of the ceramic to be fired, thereby making the heat contacting the surface of the ceramic to be fired more uniform, which is beneficial to improving the quality of ceramic firing.

[0027] Two pressing blocks 6 are provided on the lower support seat 23, and the bottom surfaces of the two pressing blocks 6 are provided with arc-shaped grooves matching the lower support seat 23. The two pressing blocks 6 are distributed on both sides of the lower support seat 23, and the lower support seat 23 is located in the arc-shaped grooves of the pressing blocks 6. The bottom surfaces of the pressing blocks 6 are in contact with the top surface of the kiln car cover plate 1. Through holes are provided on the pressing blocks 6, and threaded holes matching the through holes are provided on the kiln car cover plate 1. When necessary, the pressing blocks 6 can be fixed to the kiln car cover plate 1 by bolts.

[0031] When the present invention is working, a plurality of fixed support columns 2 arranged at equal intervals in the vertical and horizontal directions are placed on the kiln car cover plate 1, such as Figure 1 As shown, a support beam 4 is placed between the upper support seats 22 of two adjacent fixed support columns 2. After all the support beams 4 are placed, the fixing block 24 is installed on the upper support seat 22 so that the T-shaped block 25 of the fixing block 24 is located in the T-shaped slot 26 of the support beam 4, and then the support beam 4 is clamped on the upper support seat 22. All the support beams 4 are connected together to form a mesh structure, and then the support beam 4 is indirectly fixed to the upper support seat 22 by fixing bolts 29, that is, the fixing bolts 29 fix the fixing block 24 on the upper support seat 22, and the T-shaped pressing plate 28 is pressed on the support beam 4, which limits and fixes the support beam 4, further improving the stability of the present invention, and then the shelf 3 is placed on the support beam 4. The top surface of the support beam 4 is horizontal, the shelf 3 can fit well with the top surface of the support beam 4, and the support beam 4 is more evenly stressed. The fixed support column 2 and the support beam 4 of the present invention can be firmly connected together, thereby increasing the stability of the present invention and solving the problem of easy tipping during loading of blanks.
