[0024] Exemplary embodiments will now be described more fully with reference to the accompanying drawings. However, these exemplary embodiments can be implemented in many forms and should not be construed as limited to the examples set forth herein; rather, they are provided so that the description of this disclosure will be more complete and fully convey the concept of the exemplary embodiments to those skilled in the art. The drawings are merely illustrative of this disclosure and are not necessarily drawn to scale. The same reference numerals in the drawings denote the same or similar parts, and therefore repeated descriptions of them will be omitted.

[0025] This utility model provides a muffle furnace assembly structure, such as Figure 1 and 2As shown, the furnace includes a muffle furnace 1 with a sealed door 4 on its outer end face. The muffle furnace 1 has a heating chamber 6 inside the sealed door 4. The heating chamber 6 has a first support plate 9 and a second support plate 10 arranged in sequence inside. Multiple smaller crucibles can be placed on the first support plate 9 and the second support plate 10, thereby effectively utilizing the limited space inside the heating chamber 6 and increasing the efficiency of heating the crucibles.

[0026] The lower end of the muffle furnace 1 is provided with a support foot 3. The connection between the muffle furnace 1 and the sealed box door 4 is provided with a rotating connector 5, which can support the sealed box door 4 through the rotating connector 5, thereby facilitating the rotation of the sealed box door 4 around the rotating connector 5. One side of the outer end face of the heating chamber 6 is provided with an external concave groove 8, and both sides of the inner end face of the heating chamber 6 are provided with heating rods 7, which can heat the inside of the heating chamber 6 through the heating rods 7.

[0027] The end faces of the first support plate 9 and the second support plate 10 are both provided with strip grooves 11, which can effectively increase the uniformity of heat inside the heating chamber 6. At the same time, when removing the crucible, the operator hooks the hooks onto the strip grooves 11, which makes it easy to pull the first support plate 9 and the second support plate 10 out of the heating chamber 6, increasing the convenience of removing the crucible. There are multiple support feet 3, which are arranged in an array on both sides of the vertical central axis of the muffle furnace 1 when viewed from above. The control panel 2 is electrically connected to the external control equipment.

[0028] The rotating connectors 5 are provided in multiple quantities and are arranged in an array on both sides of the transverse central axis in the main view direction of the muffle furnace 1. The rotating connectors 5 can support the sealing box door 4, so that the sealing box door 4 can rotate around the center point of the rotating connectors 5. The heating rod 7 is electrically connected to the external control device. The strip grooves 11 are provided in multiple quantities and are arranged in an array on both sides of the transverse central axis in the top view direction of the first support plate 9 and the second support plate 10.

[0029] like Figure 3 and 4 As shown, a support block 21 is provided in the middle of both sides of the inner end of the heating cavity 6. A support groove 17 is provided on the end face of the support block 21. A limiting support block 20 is provided on the outer end face of the first support plate 9. Bottom support blocks 18 are provided on both sides of the lower end of the heating cavity 6.

[0030] The lower sides of both ends of the second support plate 10 are provided with limiting support grooves 19. When the support groove 17 and support block 21, and the bottom support block 18 and limiting support grooves 19 are in a compatible state, the operator can easily pull the first support plate 9 and the second support plate 10 out of the heating chamber 6. This makes it convenient to place multiple smaller crucibles on the upper end of the first support plate 9 and the second support plate 10 and push them into the heating chamber 6, thus facilitating the heating of multiple small crucibles. At the same time, when removing the small crucibles, the first support plate 9 and the second support plate 10 can also be pulled out of the heating chamber 6. The interior of cavity 6 is pulled out, which increases the convenience of taking out small crucibles. At the same time, when placing and heating larger crucibles, the operator can take out the first support plate 9 and the second support plate 10 from the interior of heating cavity 6, which makes it convenient to place and take out larger crucibles. The outer end face of the muffle furnace 1 is provided with a rotating support block 14 and a control panel 2 on the side near the sealing box door 4. The heating rod 7 can be driven by the control panel 2 to work, thereby heating the interior of heating cavity 6. The inner end face of the rotating support block 14 is provided with a rotating support rod 15.

[0031] The outer end face of the rotating support rod 15 is provided with a threaded rod 16, and the outer end face of the threaded rod 16 is provided with a rotating locking member 13. When the rotating locking member 13 is rotated, the internal thread of the locking member 13 will engage with the thread of the outer end face of the threaded rod 16. The outer end face of the sealing box door 4 is provided with a locking member 12 at the end away from the rotating connector 5. When the sealing box door 4 is closed and locked, the threaded rod 16 can be rotated and locked into the inside of the locking member 12. Then, the rotating locking member 13 is sleeved on the outer end face of the threaded rod 16 and the rotating locking member 13 is rotated. When the rotating locking member 13 rotates, it will move to one side, so that the rotating locking member 13 abuts against the locking member 12 and presses it, thereby effectively increasing the sealing performance of the sealing box door 4 when closed and locked. The number of support blocks 21 is multiple, and they are arranged in an array on both sides of the transverse central axis in the top view of the heating chamber 6.

[0032] Multiple support blocks 21 and heating rod 7 are arranged in a staggered state in the top view direction. The inner end face of the support groove 17 in the main view direction is adapted to the outer end face of the limiting support block 20 in the main view direction. The outer end face of the bottom support block 18 in the main view direction is adapted to the outer end face of the limiting support groove 19 in the main view direction.

[0033] The outer end face of the threaded rod 16 is engaged with the inner end face of the rotating locking member 13 by a thread. The locking member 12 is arranged in a U-shape in the main viewing direction, and the inner end face of the locking member 12 is in contact with the outer end face of the threaded rod 16.
