[0022] The technical scheme in the embodiments of the utility model will be described clearly and completely below in conjunction with the drawings in the embodiments of the utility model, and obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by the person skilled in the art without making creative labor are within the protection scope of the utility model.

[0023] Embodiment 1 please see Figures 1-4 The utility model provides a technical scheme:

[0024] The application discloses a middle shaft structure capable of enhancing support capacity, which comprises a middle shaft supporting rod 1, a middle shaft supporting disc 2 arranged at the top end of the middle shaft supporting rod 1, a supporting disc 3 arranged at the bottom of the middle shaft supporting disc 2, three mounting seats 4 arranged on the surface of the supporting disc 3, a connecting seat 5 arranged on the surface of the mounting seat 4, a moving block 6 arranged on the bottom surface of the connecting seat 5, a sliding groove matched with the moving block 6 arranged on the surface of the mounting seat 4, the connecting seat 5 and the mounting seat 4 being slidably connected through the moving block 6 and the sliding groove, an arc-shaped rod 7 arranged on the surface of the side of the connecting seat 5 close to the middle shaft supporting disc 2, a base supporting block 8 arranged on the surface of the middle shaft supporting disc 2, a guide rod 9 slidably connected in a through hole arranged on the surface of the moving block 6, both ends of the guide rod 9 penetrating through the moving block 6 and being arranged in the sliding groove arranged on the surface of the mounting seat 4, a reset spring 10 sleeved on the surface of the guide rod 9, one end of the reset spring 10 being connected with the moving block 6, and the other end of the reset spring 10 being arranged in the sliding groove arranged on the surface of the mounting seat 4.

[0025] Specifically, as shown in the figure, the middle shaft supporting disc 2 is arranged in a "recessed triangular structure", and is made of carbon composite material with high strength and low density; and the middle shaft supporting rod 1 is internally provided with reinforcing ribs for improving the support capacity of the middle shaft supporting rod 1. Figure 1

[0026] In the embodiment, the crucible is first placed on the middle shaft supporting disc 2 of the middle shaft supporting rod 1. Since the middle shaft supporting disc 2 is arranged in a "recessed triangular structure" and is made of carbon composite material with high strength and low density, the crucible is combined with the middle shaft supporting disc 2 by triangular fixing method. The triangular structure greatly reduces the weight of the middle shaft supporting rod 1 and stably and quickly concentrates the weight of the crucible on the middle shaft supporting rod 1. The reinforcing ribs added to the middle shaft supporting rod 1 improve the support capacity of the middle shaft supporting rod 1, the longitudinal thickness of the middle shaft supporting rod 1 is reduced by 50 mm, the material loading capacity is increased, the hot field space is enlarged, the hot field components are optimized, the hot field loading capacity is improved, and the yield is increased. When the crucible is placed on the middle shaft supporting disc 2, the base supporting block 8 supports the bottom of the crucible. At this time, the crucible extrudes the arc-shaped rod 7, the arc-shaped rod 7 drives the connecting seat 5 to move, the connecting seat 5 slides in the sliding groove arranged on the surface of the mounting seat 4 through the moving block 6, the moving block 6 slides on the surface of the guide rod 9, the guide rod 9 guides the moving position of the moving block 6 to avoid the position deviation of the moving block 6 during movement. At this time, the moving block 6 extrudes the reset spring 10, so that the reset spring 10 is deformed. After the crucible is placed on the middle shaft supporting disc 2, the elastic force of the reset spring 10 restored to the original shape extrudes the moving block 6, and then the arc-shaped rod 7 clamps and fixes the crucible to stabilize the position of the crucible.

[0027] Embodiment 2 is shown in the figure Figure 1 , Figure 2 and​Figure 4 The difference between this embodiment and embodiment 1 is that: a lifting block 11 is installed at the triangular part of the central shaft tray 2, and multiple anti-slip pads 12 are distributed on the surface of the lifting block 11.

[0028] Specifically, such as Figures 1-4 As shown, the arc-shaped rods 7 are symmetrically distributed above the central shaft tray 2, and the arc-shaped rods 7 correspond one-to-one with the triangles of the central shaft tray 2.

[0029] In this implementation scheme: By setting a central support rod 1, when the crucible is placed on the central support tray 2, the lifting block 11 on the central support rod 1 supports the crucible, thereby making the crucible stably placed in the central support rod 1 and preventing the crucible from falling from the central support tray 2 during use. The anti-slip pad 12 on the lifting block 11 can further improve the stability of the crucible on the central support rod 1 and prevent the crucible from slipping off the lifting block 11. The arc-shaped rods 7 correspond one-to-one with the triangular parts of the central support tray 2, so that the three arc-shaped rods 7 can simultaneously squeeze the crucible, thereby clamping the crucible and further improving the stability of the crucible's position, preventing the crucible from falling from the central support rod 1.

[0030] Although 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 alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
