[0002] A smelting furnace is a device that melts metal ingots and some scrap metals, adds necessary alloying components, and then melts them into the desired alloy through operations such as slag removal and refining. Since the surface material of the smelting furnace is metal, the surface of the smelting furnace is conductive. In order to ensure safety, the current generated by the smelting furnace during use needs to be conducted into the ground through a grounding device.

[0003] However, most existing grounding devices are fixed and cannot be disassembled, making it inconvenient to maintain or repair them and reducing their practicality. Therefore, corresponding improvements are needed to address these issues. Utility Model Content

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] according to Figures 1-4As shown, the furnace includes a smelting furnace body 1. A wire 11 is electrically connected to the side surface of the smelting furnace body 1, and a sleeve 12 is connected to the bottom end of the wire 11. A threaded groove 13 is opened at the bottom end of the sleeve 12. A threaded post 14 is screwed into the inside of the threaded groove 13, and a grounding rod 15 is installed at the bottom end of the threaded post 14. The grounding rod 15 is buried deep in the soil. A fixing ring 16 is installed near the top of the side surface of the sleeve 12, and a fixing hole 17 is opened on the side surface of the fixing ring 16.

[0021] A mounting plate 2 is installed on the bottom side surface of the smelting furnace body 1, and a through hole 21 is provided inside the mounting plate 2. The outer diameter of the sleeve 12 is adapted to the inner diameter of the through hole 21, and the bottom end of the sleeve 12 passes through the through hole 21 into the interior of the mounting plate 2. Limiting rings 22 are installed on both sides of the top of the mounting plate 2 near the through hole 21. The curvature of the inner wall of the limiting ring 22 is adapted to the curvature of the side surface of the fixed ring 16, and the inner wall of the limiting ring 22 is fitted to the side surface of the fixed ring 16. The two sets of limiting rings 22 can limit the fixed ring 16. A side plate 23 is installed on the other side of the top of the mounting plate 2 near the through hole 21, and a fixed part is movably arranged inside the side plate 23. The outer diameter of the fixed rod 24 is adapted to the inner diameter of the fixing hole 17, and one end of the fixed rod 24 extends into the interior of the fixing hole 17 and is slidably limited and locked with it. One end of the fixed rod 24 is equipped with a mounting plate 25, and one end of the mounting plate 25 is equipped with a hand handle 26. A mounting block 27 is installed on one side of the side plate 23 near the top, and a screw 28 is movably screwed into the interior of the mounting block 27. A magnet rod 29 is installed at the bottom end of the screw 28 through a bearing. The magnet rod 29 is arc-shaped, and the arc of the inner wall of the magnet rod 29 is adapted to the arc of the side surface of the mounting plate 25. The inner wall of the magnet rod 29 will fit against the side surface of the mounting plate 25 and be adsorbed and fixed accordingly.

[0022] When maintenance is required on the grounding rod 15, the user can rotate the screw 28, causing the magnet rod 29 to move upwards. This allows the inner wall of the magnet rod 29 to separate from the side surface of the mounting plate 25. Afterwards, the mounting plate 25 can be moved away from the side plate 23 by holding the lever 26, causing the fixing rod 24 to move accordingly. This allows one end of the fixing rod 24 to move out of the fixing hole 17. Then, the sleeve 12 can be moved upwards, causing the grounding rod 15 to move upwards and thus be removed from the soil. The grounding rod 15 is moved out of the mounting plate 2 through the through hole 21. After that, the user can rotate the grounding rod 15, so that the threaded post 14 can rotate accordingly inside the threaded groove 13, so that the threaded post 14 can rotate out inside the threaded groove 13, thereby completing the disassembly between the grounding rod 15 and the sleeve 12. Then, following the above operation, the operation is reversed to install the new grounding rod 15 at the bottom end of the sleeve 12. After that, the new grounding rod 15 can be reinserted into the soil, and the fixing ring 16 is fixedly installed by the fixing rod 24, so that the grounding rod 15 can be used normally.

[0023] 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.
