Detailed Implementation

[0019] The technical solution of this patent will be further described in detail below with reference to specific embodiments.

[0020] like Figure 1-4 As shown, this utility model provides a technical solution: a heat exchange material rack for a heat treatment furnace, including a base 1, multiple guide columns 2 connected above the base 1, a threaded rod 3 connected to the base 1, a placement plate 4 installed on the threaded rod 3, multiple enclosure grid plates 5 connected to the placement plate 4, and multiple guide column sleeves 6 connected to the placement plate 4. The guide column sleeves 6 are slidably connected to the guide columns 2. The threaded sleeves 8 and connecting sleeves 9 are both threadedly engaged with the threaded rod 3. When the threaded sleeves 8 drive the placement plate 4 to move along the threaded rod 3, the guide column sleeves 6 will slide on the guide columns 2, thereby guiding and restricting the movement of the placement plate 4 through the guide columns 2, preventing the placement plate 4 from tilting during movement and improving the stability of movement.

[0021] The placement plate 4 has multiple through holes 7. A threaded sleeve 8 is rotatably connected to the placement plate 4. A connecting sleeve 9 is connected below the threaded sleeve 8. Multiple connecting rods 10 are connected to the connecting sleeve 9. Friction grooves 18 are provided at the contact point between the threaded sleeve 8 and the placement plate 4. The connecting rods 10 are L-shaped and there are four of them. The four connecting rods 10 are distributed symmetrically on the connecting sleeve 9. The multiple connecting rods 10 make it easy for the operator to turn the connecting sleeve 9 to rotate the threaded sleeve 8, thereby adjusting the position of the placement plate 4. The friction grooves 18 on the threaded sleeve 8 can increase friction and prevent the threaded sleeve 8 from rotating accidentally.

[0022] A top plate 11 is installed on the guide column 2, and a fixing plate 12 is connected to the top plate 11. There are four guide columns 2 arranged in a rectangular array. The guide column 2 has a plug hole 17. The fixing plate 12 is plugged into the plug hole 17. By plugging the fixing plate 12 into the plug hole 17, it is convenient for the staff to install the top plate 11. The operation is simple and convenient, and the processing efficiency is improved.

[0023] A hanging ring 13 is connected above the top plate 11, and a fixing rod 14 is connected to the top plate 11. A connecting plate 15 is rotatably connected to the fixing rod 14. Torsion springs 19 are sleeved at both ends of the fixing rod 14. One end of the torsion spring 19 is connected to the top plate 11, and the other end of the torsion spring 19 is connected to the connecting plate 15. Through the elasticity and restriction of the torsion spring 19, the movable rod 16 can move closer to the slot 20 on its own, and the movable rod 16 and the connecting plate 15 can be prevented from rotating accidentally, thus making it convenient for workers to install and fix the top plate 11.

[0024] A movable rod 16 is connected to the connecting plate 15. A slot 20 is provided on one side of the fixed plate 12. The movable rod 16 is fitted into the slot 20. The movable rod 16 and the slot 20 are specifically interference fit, so that the operator can knock or push the movable rod 16 to make it snap into the slot 20, thereby preventing the fixed plate 12 from sliding. Moreover, the operation is simple and easy to install and disassemble.

[0025] The working principle of this utility model is as follows:

[0026] During assembly, the workers attach the connecting sleeve 9 and the threaded sleeve 8 to the threaded rod 3, and push the connecting rod 10 to cause the connecting sleeve 9 to drive the threaded sleeve 8 to rotate. This allows the placement plate 4 to move on the threaded rod 3 through the threaded engagement between the threaded sleeve 8 and the threaded rod 3. By rotating the threaded sleeve 8, the distance between multiple placement plates 4 can be adjusted to accommodate materials of different heights and sizes, and the number of placement plates 4 on the threaded rod 3 can be controlled, thereby improving applicability and utilization. Then, by rotating the movable rod 16, the movable rod 16 is disengaged from the slot 20, causing the connecting plate 15 to rotate on the fixed rod 14 and twist the torsion spring 19. Then, the fixed plate 12 is inserted into the insertion hole 17. Finally, the movable rod 16 is released, causing the torsion spring 19 to rotate and drive the movable rod 16 to rotate. By tapping or pushing the movable rod 16, the movable rod 16 is locked into the slot 20 to fix the fixed plate 12 and prevent it from sliding, thus completing the installation and fixing of the top plate 11.
