It should be understood that spatial relative terms are intended to encompass different orientations in use or operation beyond the orientation of the device as described in the figures. For example, if the device in the figures were inverted, a device described as "above" or "on top of" other devices or structures would subsequently be positioned as "below" or "under" other devices or structures. Thus, the exemplary term "above" can include both "above" and "below." The device may also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatial relative descriptions used herein will be interpreted accordingly.

[0034] Please see Figure 1-6 This utility model provides a technical solution: an electric fused magnesia furnace, including an electric fused furnace body 1, a support leg 2, a clamp 3, a bottom plate 4, a support column 5, an electric telescopic rod 6, a side bolt 7, a side nut 8, a mounting groove 9, a top plate 10, a rotating shaft 11, a base plate 12, a locking bolt 13, a locking nut 14, a limiting groove 15, a mounting plate 16, and a monitoring probe 17. The support leg 2 is installed at the bottom of the electric fused furnace body 1, and the clamp 3 is installed on the support leg 2. One side of the clamp 3 is connected and fixed to one end of the bottom plate 4.

[0035] An electric telescopic rod 6 is provided on the inner side of the other end of the base plate 4. A side bolt 7 is fixed on one side of the bottom of the electric telescopic rod 6. A side nut 8 is installed at the end of the side bolt 7. The side bolt 7 passes through the mounting groove 9. The mounting groove 9 is opened in the vertical part of the base plate 4. A top plate 10 is fixedly installed at the top of the electric telescopic rod 6.

[0036] A rotating shaft 11 is installed at one end of the middle of the inner side of the top plate 10. The rotating shaft 11 is connected to the side of the base plate 12. A mounting plate 16 is fixed at one end of the base plate 12. A monitoring probe 17 is fixed on the mounting plate 16.

[0037] On the bottom surface of the other end of the bottom plate 4 in this example, a support column 5 is fixedly installed, and the bottom end of the support column 5 and the bottom end of the support leg 2 are on the same horizontal plane. The above structural design can stably support the bottom plate 4 and prevent the bottom plate 4 from deforming.

[0038] In this example, the front view shape of the bottom plate 4 is "L"-shaped, and the center of the bottom plate 4 and the center of the support column 5 are on the same vertical plane. The above structural design enables the bottom plate 4 to provide a stable installation foundation for the electric telescopic rod 6.

[0039] In this example, the side bolt 7 and the installation groove 9 are slidably connected, and the side view shape of the installation groove 9 is "U"-shaped. The above structural design facilitates the installation and disassembly of the electric telescopic rod 6.

[0040] In this example, the side view width of the installation groove 9 is smaller than the diameter of the electric telescopic rod 6, and the center of the electric telescopic rod 6 and the center of the bottom plate 4 are on the same horizontal plane. The above structural design enables the bottom plate 4 to stably support the electric telescopic rod 6, and the side surface of the electric telescopic rod 6 can be stably fitted with the installation groove 9.

[0041] In this example, the side surface of the base plate 12 is fitted with the inner side surface of the top plate 10, and the side view shape of the top plate 10 is "凵"-shaped. The above structural design enables the base plate 12 to be stably installed and rotationally adjusted inside the top plate 10.

[0042] In this example, a locking bolt 13 is fixed on the side surface of the base plate 12, a locking nut 14 is installed at the end of the locking bolt 13, the locking bolt 13 passes through the limiting groove 15, and the limiting groove 15 is opened at the other end of the vertical part of the top plate 10. The above structural design enables the base plate 12 to have high stability both when it is fixedly used and when it is rotationally adjusted.

[0043] In this example, the locking bolt 13 and the limiting groove 15 are slidably connected, and both the locking bolt 13 and the limiting groove 15 are symmetrically distributed about the center of the base plate 12. The above structural design enables the base plate 12 to stably rotate and slide along the limiting groove 15 with the locking bolt 13 when it rotates.

[0044] In this example, the limiting groove 15 is set to be arc-shaped, and the center of the circle where the arc side of the limiting groove 15 is located coincides with the center of the rotating shaft 11. The above structural design enables the locking bolt 13 to follow the base plate 12 and smoothly slide in the limiting groove 15 to change the working position.

[0045] Working principle: During installation, first install the clamp 3 on the support leg 2 near the observation window side, connect and fix the bottom end of the support column 5 to the installation surface, adjust the inclination angles of the base plate 12, the mounting plate 16 and the monitoring probe 17 according to the position of the observation window on the top of the electric melting furnace body 1, and then toggle Figure 2At the left end of the substrate 12, rotate the substrate 12 clockwise around the pivot 11. The substrate 12, with the locking bolt 13, slides stably along the limiting groove 15 until the tilt angle of the substrate 12, mounting plate 16 and monitoring probe 17 is appropriate. Then, rotate the symmetrically distributed locking nuts 14 to press the outer side of the top plate 10 to fix the substrate 12, mounting plate 16 and monitoring probe 17.

[0046] Erect the electric telescopic rod 6 along with the top plate 10. The bottom end of the electric telescopic rod 6 is attached to the inner corner of the base plate 4. The side bolt 7 is slid into the mounting groove 9. Install the side nut 8 at the end of the side bolt 7 and tighten it. Connect and fix the bottom end of the electric telescopic rod 6 to the base plate 4. Control the extension and retraction of the electric telescopic rod 6 to drive the top plate 10, base plate 12, mounting plate 16 and monitoring probe 17 to move vertically. When the distance between the monitoring probe 17 and the observation window is appropriate, control the electric telescopic rod 6 to lock. The monitoring probe 17 can then conduct stable observation and monitoring through the observation window.

[0047] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the scope of protection of the present utility model.
