DETAILED DESCRIPTION

[0023] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0024] The terms "upper", "lower", "left", "right", "middle" and "one" used in the present invention are only for the convenience of description and are not intended to limit the scope of application of the present invention. Changes or adjustments to their relative relationships shall be deemed to be within the scope of application of the present invention without substantially changing the technical content.

[0025] Reference Figure 1-Figure 7 A main heater structure includes a main heating plate 1, a ring-shaped opening is opened at the bottom of the main heating plate 1, and mounting openings are symmetrically opened in the ring-shaped opening. A hollow rod 2 with a closed bottom end is fixedly installed in the mounting opening, and a suction cup 3 is fixedly installed at the bottom end of the hollow rod 2.

[0026] A rotating opening is provided at the top of the hollow rod 2, and a rotating shaft 4 is sealed and rotatably installed in the rotating opening. One end of the rotating shaft 4 located in the hollow rod 2 is fixedly installed with a closing plate 5 through a connecting rod. A through opening 6 is provided on the surface of the hollow rod 2, and the closing plate 5 is used to cover the through opening 6. The rotating shaft 4 is connected to the hollow rod 2 through an elastic component. The elastic component includes a torsion spring 7 sleeved on the rotating shaft 4. A gear 8 is fixedly installed on the top of the rotating shaft 4. The two ends of the torsion spring 7 are fixedly connected to the gear 8 and the hollow rod 2 respectively. The two rotating shafts 4 are controlled to rotate together through a transmission assembly. The transmission assembly includes a gear ring 9 meshing with the two gears 8. Slide rods 10 are symmetrically fixedly installed on the upper surface of the gear ring 9. An annular groove 11 is provided on the top wall of the annular opening. The top ends of the two slide rods 10 are slidably configured in the annular groove 11, and an L-shaped mounting plate 12 is symmetrically fixedly installed on the outer ring wall of the gear ring 9.

[0027] When the main heating plate 1 needs to be installed, it is only necessary to turn the two suction cups 3 located at the bottom of the main heating plate 1 downward and insert them into the installation position of the crucible so that the suction cups 3 are tightly against the bottom wall of the installation position. At this time, the suction cups 3 will be deformed by the pressing force, and the gas in the suction cups 3 will slip out from the gap between the suction cups 3 and the contact surface of the crucible, so that the two suction cups 3 will be attracted to the crucible, thereby completing the fixation of the main heating plate 1. When it is necessary to disassemble, it is only necessary to control the two mounting plates 12 to rotate with the gear ring 9. At this time, the two are both in contact with the gear ring. The gear 8 meshing with the ring 9 will respectively drive the two rotating shafts 4 to rotate, and the two closing plates 5 will also rotate together until the closing plates 5 no longer cover the through openings 6. At this time, the gas in the outside will enter the suction cup 3 from the through openings 6, thereby releasing the adsorption of the suction cup 3, which is convenient and quick. When the mounting plate 12 is released, the two gears 8 will respectively rotate and reset rapidly under the elastic potential energy of the two torsion springs 7, and the two closing plates 5 will also rotate and reset to cover the two through openings 6 again, and the gear ring 9 will also rotate and reset together with the rotation of the two gears 8.

[0028] A rectangular opening is provided on the surface of the mounting plate 12, and a locking assembly is provided inside the rectangular opening. The locking assembly is used to lock the gear ring 9. The locking assembly includes a threaded rod 13 vertically rotatably installed in the rectangular opening, a slide 14 threadedly sleeved on the threaded rod 13, and a locking rod 15 fixedly installed on the upper surface of the slide 14. Two locking grooves 16 are symmetrically provided on the top of the annular opening for inserting the ends of the two locking rods 15 respectively. The top end of the threaded rod 13 passes through the mounting plate 12 and is fixedly installed with an adjusting wheel.

[0029] Then, by rotating the two threaded rods 13, the two slides 14 are controlled to move up with the two locking rods 15 respectively, until the top ends of the two locking rods 15 are respectively inserted into the two locking grooves 16, and the gear ring 9 can be locked. At this time, the gear ring 9 cannot rotate, and the two gears 8 cannot rotate with the two rotating shafts 4, and then the two through ports 6 will always be in a closed state, and the outside air cannot enter the suction cup 3 from the through port 6, which can improve the adsorption stability of the suction cup 3 and avoid being affected by external vibration force, which causes the gear ring 9 to rotate, so that the two gears 8 will rotate with the two rotating shafts 4 and the two closing plates 5 respectively, and the closing plate 5 no longer covers the through port 6, and the air at the outside enters the suction cup from the through port 6.

[0030] When the gear ring 9 needs to be controlled to rotate, the control slide 14 moves downward with the locking rod 15 by rotating the threaded rod 13 until the top ends of the two locking rods 15 are respectively moved out of the two locking grooves 16 to release the lock of the gear ring 9, and then the gear ring 9 can be controlled to rotate.

[0031] When the main heating plate 1 needs to be installed, it is only necessary to turn the two suction cups 3 at the bottom of the main heating plate 1 downward and press them tightly against the surface of the crucible. At this time, the suction cups 3 will be deformed by the pressing force, and the gas in the suction cups 3 will slip out from the gap between the suction cups 3 and the contact surface of the crucible, so that the two suction cups 3 will be attracted to the crucible, thereby completing the fixation of the main heating plate 1. When it needs to be disassembled, it is only necessary to control the two shafts 4 to rotate together through the transmission assembly, and the two closing plates 5 will also rotate together until the closing plates 5 no longer cover the through openings 6. At this time, the gas in the outside will enter the suction cups 3 from the through openings 6, thereby releasing the adsorption of the suction cups 3. It is convenient and quick, avoiding the tedious steps of using screw and nut fixings, and the main heating plate 1 can be quickly disassembled and assembled without the aid of special tools.

[0032] In the present invention, unless otherwise clearly specified or limited, the terms “installed”, “connected”, “connected”, “fixed” and the like should be understood in a broad sense.

[0033] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
