[0019] The technical solutions in the embodiments of the present invention will be described clearly and completely below with reference to the accompanying drawings in the embodiments of the present invention.

[0020] The utility model provides a technical solution: Figures 1 to 4 As shown, in this embodiment, a layered bracket for use in a high-temperature furnace includes a high-temperature furnace body 1, a furnace slot 2 is opened inside the high-temperature furnace body 1, a bracket body 3 is arranged in the furnace slot 2, the bracket body 3 is composed of a fixed bottom plate 4, a fixed top plate 5 and a movable frame 6, a plurality of movable frames 6 are distributed between the fixed bottom plate 4 and the fixed top plate 5, and an adjustment mechanism acting on the movable frame 6 is also arranged between the fixed bottom plate 4 and the fixed top plate 5, and the adjustment mechanism is composed of an adjustment sleeve 7 and an adjustment column 8.

[0021] Among them, four adjusting columns 8 are fixedly connected between the fixed bottom plate 4 and the fixed top plate 5. The four adjusting columns 8 are respectively distributed at the four corners of the fixed bottom plate 4. The four adjusting columns 8 respectively pass through the four through holes 9 opened in the movable frame 6. The bottom of the movable frame 6 is rotatably connected with four adjusting sleeves 7. The four adjusting sleeves 7 are respectively sleeved on the four adjusting columns 8. The outer surface of the adjusting column 8 is provided with an external thread, and the inner wall of the adjusting sleeve 7 is provided with an internal thread. The adjusting sleeve 7 and the adjusting column 8 are connected by threaded cooperation.

[0022] When in use, the adjusting sleeve 7 is rotated to control the adjusting sleeve 7 to move up and down on the adjusting column 8. By adjusting four adjusting sleeves 7 at the same time, the height of the movable frame 6 can be adjusted. According to actual needs, the height of multiple movable frames 6 can be adjusted to ensure that the gaps between the movable frames 6 can be suitable for heating objects of different volumes, and the scope of application is wider.

[0023] The diameter of the through hole 9 is larger than the diameter of the adjusting column 8 .

[0024] This arrangement can ensure that the movable frame 6 does not interfere with the adjustment column 8 when moving up and down.

[0025] The distance between the lower surface of the fixed bottom plate 4 and the upper surface of the fixed top plate 5 is equal to the inner cavity height of the furnace tank 2 .

[0026] With such arrangement, after the bracket body 3 is placed into the furnace groove 2 , the upper and lower ends of the bracket body 3 just abut against the upper and lower inner walls of the furnace groove 2 , thereby preventing the bracket body 3 from shaking at will.

[0027] The fixed bottom plate 4 , the fixed top plate 5 , the movable frame 6 , the adjustment sleeve 7 and the adjustment column 8 are all made of polycrystalline fiber material.

[0028] This can ensure that the bracket body 3 has good high temperature resistance.

[0029] The upper surface of the movable frame 6 is frosted, and the sides of the fixed bottom plate 4 and the fixed top plate 5 that are away from each other are polished.

[0030] Such an arrangement can increase the friction between the material and the movable frame 6, reduce the friction between the fixed bottom plate 4 and the fixed top plate 5, and avoid wear on the inner wall of the furnace tank 2 during the process of pulling out the bracket body 3.

[0031] The utility model provides a layered bracket for high temperature furnace, and the specific working principle is as follows:

[0032] By setting the bracket body 3, the interior of the furnace trough 2 can be divided into multiple layers. When a large amount of materials are placed at a time, the materials will not be overly accumulated, which can effectively improve the utilization efficiency of the furnace trough 2. At the same time, by rotating the adjusting sleeve 7, the adjusting sleeve 7 can be controlled to move up and down on the adjusting column 8. By adjusting the four adjusting sleeves 7 at the same time, the height of the movable frame 6 can be adjusted. According to actual needs, the height of multiple movable frames 6 can be adjusted to ensure that the gaps between the movable frames 6 can be suitable for heating objects of different volumes, and the scope of application is wider.

[0033] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
