The negative electrode end in the device of this document can slide along the limit slide mainly through the internal counterweight to realize the opening and closing of the positive and negative electrode ends. However, during the rotation of the fixed frame, once the negative electrode end is blocked when sliding, it will cause the two sets of positive and negative electrode ends to close or open at the same time, thereby causing a circuit failure. For this reason, we propose a furnace changing switch fixing component. Utility Model Content

[0024] like Figure 1 and Figure 4 As shown, a furnace changer switch fixing assembly includes a mounting base 1, a first conductive assembly and a second conductive assembly are movably mounted on the top of the mounting base 1, an insulating block 15 for limiting is mounted on the movable end of the second conductive assembly, a fixing plate 23 is fixedly connected to the top of the mounting base 1, a connecting base 24 is fixedly connected to the inclined end of the fixing plate 23, and two elastic clips 25 are fixedly connected to the upper end of the connecting base 24 in a symmetrical structure, and the relatively close sides of the two elastic clips 25 are convex inward to form a limiting protrusion 26.

[0025] like Figure 1 and Figure 2 As shown, the first conductive component includes two first sliders 5, the inner walls of the two first sliders 5 are slidably connected with the first slide rods 3, the outer walls of the two first slide rods 3 are sleeved with first springs 4, the tops of the two first sliders 5 are fixedly connected with conductive input blocks 6, the top of the mounting seat 1 is symmetrically structured with two first mounting holes 2, the two first sliders 5 are respectively slidably connected to the inner walls of the first mounting holes 2, the ends of the two first slide rods 3 are respectively connected and fixed to the inner walls of the first mounting holes 2, the outer walls of the two conductive input blocks 6 are fixedly connected with guide blocks 7, the outer walls of the two guide blocks 7 are provided with inclined surfaces 8, one end of the first spring 4 is fixedly connected to the inner wall of the first mounting hole 2, and the other end of the first spring 4 is connected to the first slider 5 Fixed. After the switch is closed, the two ends of the insulating block 15 are used to squeeze the end of the conductive input block 6, so that one end of the conductive part 14 can be limited to prevent the conductive part 14 from being separated from the contact with the two conductive input blocks 6; after the switch is opened, the insulating block 15 can abut the two guide blocks 7 to prevent the conductive part 14 from being separated from the contact with the two conductive input blocks 6. When pressed, the insulating rod 22 squeezes the elastic clips 25 on the two connecting seats 24, so that the two elastic clips 25 bend outward until the insulating rod 22 is stuck on the inner side of the two elastic clips 25. The insulating rod 22 is limited and fixed by the limiting protrusion 26. This design can improve the safety of the switch opening and closing process and avoid circuit failure.

[0026] like Figure 2 and Figure 3 As shown, the second conductive component includes a connecting rod 16, the end of the connecting rod 16 is fixedly connected to a push block 13, the outer wall of the push block 13 is fixedly connected to a conductive part 14, the outer end of the conductive part 14 is connected and fixed to an insulating block 15, the circumferential outer wall of the connecting rod 16 is fixedly connected to a limiting rod 17 in a penetrating manner, the bottom of the push block 13 is fixedly connected to a second slider 12, the inner wall of the second slider 12 is slidably connected to a second slider 10, the circumferential outer wall of the second slider 10 is sleeved with a second spring 11, a second mounting hole 9 is opened at the top of the mounting seat 1, the second slider 12 is slidably connected to the inner wall of the second mounting hole 9, the end of the second slider 10 is connected and fixed to the inner wall of the second mounting hole 9, one end of the second spring 11 is connected and fixed to the second slider 12, and the other end of the second spring 11 is connected and fixed to the inner wall of the second mounting hole 9.

[0027] like Figure 2 As shown, the top of the mounting base 1 is symmetrically structured and fixedly connected to two support blocks 19, a rotating shaft 20 is rotatably connected between the two support blocks 19, a connecting frame 21 is fixedly connected to the circumferential outer walls of the two rotating shafts 20, an insulating rod 22 is fixedly connected to the end of the connecting frame 21, and two slots 18 are provided on the outer wall of the insulating rod 22, and the two ends of the limit rod 17 are slidably connected to the inner walls of the slot 18 respectively.

[0028] The conductive input block 6 and the conductive part 14 are respectively connected to the switch control circuit of the industrial electric furnace. When the conductive input block 6 and the conductive part 14 are in a separated state, the switch control circuit of the industrial electric furnace is not connected, and the industrial electric furnace does not work; when the conductive input block 6 and the conductive part 14 are in a combined state, the switch control circuit of the industrial electric furnace is connected, and the industrial electric furnace starts to work.

[0029] Working principle: by holding the insulating rod 22 and extending the rotating shaft 20 to flip the insulating rod 22, the insulating rod 22 drives the connecting frame 21 to rotate, the clamping groove 18 on the connecting frame 21 pushes the limiting rod 17 to move, and the limiting rod 17 drives the connecting rod 16 to slide back and forth;

[0030] When the connecting rod 16 slides, it can drive the push block 13 to slide. When the push block 13 slides toward the side close to the first conductive component, the second slide block 12 slides along the outer wall of the second slide bar 10. Under the pulling force of the second spring 11, the insulating block 15 at the end of the conductive part 14 squeezes the inclined surfaces 8 on the two guide blocks 7. At this time, the two guide blocks 7 respectively drive the conductive input blocks 6 to slide to both sides. The two conductive input blocks 6 respectively drive the first slide block 5 to slide along the first slide bar 3. At this time, the two first springs 4 are compressed until the conductive part 14 is inserted between the two conductive input blocks 6. Under the elastic force of the first spring 4, the inner ends of the two conductive input blocks 6 squeeze and fix the two sides of the conductive part 14 respectively.

[0031] When the push block 13 slides away from the first conductive component, the second spring 11 is slightly stretched, and the two ends of the insulating block 15 squeeze the ends of the conductive input block 6 until it moves to the other side of the two conductive input blocks 6, so that the conductive part 14 is out of contact with the two conductive input blocks 6;

[0032] When pressed, the insulating rod 22 squeezes the elastic clamping plates 25 on the two connecting seats 24, so that the two elastic clamping plates 25 bend outward until the insulating rod 22 is clamped inside the two elastic clamping plates 25, and the insulating rod 22 is limited and fixed by the limiting protrusion 26.
