[0022] Example 1:

[0023] See attached document Figures 1-6 In this embodiment, a multi-level electrical control box circuit breaker handle linkage structure includes a base 1 and a slot 2.

The inner wall of the first terminal block 4 is threadedly connected to the fixing screw 5. The inner wall of the base 1 is connected to a linkage mechanism 6.

[0024] The linkage mechanism 6 includes a round rod 601. The square strip 602 and silicone sleeve 603 on the round rod 601 are rotated by the first handle 7, so that the copper connecting strip 801 on the mounting part 604 and the conductive plate 802 are electrically linked as a whole. The end of the round rod 601 is movably connected to the base 1, the outer wall of the round rod 601 is movably connected to the square strip 602, the outer wall of the square strip 602 is fixedly connected to the silicone sleeve 603, and the outer wall of the silicone sleeve 603 is fixedly connected to the mounting part 604.

[0025] The end of the round rod 601 is fixedly connected to the first handle 7. The outer wall of the mounting part 604 is connected to the adjustment mechanism 8. By adjusting the position between the conductor connecting strip 801 and the conductive plate 802, the connecting strip 801 and the conductive plate 802 are electrically disconnected and connected. The adjustment mechanism includes the connecting strip 801. The outer wall of the connecting strip 801 is fixedly connected to the mounting part 604. The outer wall of the connecting strip 801 is slidably connected to the conductive plate 802. The outer wall of the conductive plate 802 is electrically connected to the line 803. The end of the line 803 is electrically connected to the second terminal block 804.

[0026] Turning the first handle 7 causes the square strip 602 and silicone sleeve 603 on the round rod 601 to rotate, making the copper connecting strip 801 on the mounting part 604 electrically connected to the conductive plate 802. At the same time, the first connector 4 is electrically connected to the conductive plate 802, so that the whole is in an electrically connected state. The second handle 11, which is fixed by pushing, applies external force to the mounting part 604. The silicone sleeve 603 on the inner wall of the mounting part 604 deforms and rotates, making the copper connecting strip 801 on the mounting part 604 electrically connected to the conductive plate 802. This allows for opening in a separate position, which can expand the scope of use and meet the needs of large-area applications.

[0028] Working principle:

[0029] Overall use

[0030] The power cord in the external multi-level electrical control box is electrically connected through the first connector 4 and the second connector 804. The external power cord on the first connector 4 and the second connector 804 is fixed by tightening the fixing screw 5. When the whole box needs to be opened, the first handle 7 is manually pulled and slid a certain distance on the base 1 to make the protrusion on the inner side of the first handle 7 disengage from the outer shell 10. The first handle 7 is then tightened to drive the square strip 602 and the silicone sleeve 603 on the round rod 601 to rotate, so that the copper connecting strip 801 on the mounting part 604 is electrically connected to the conductive plate 802. At the same time, the first connector 4 is electrically connected to the conductive plate 802, and the second connector 804 is electrically connected to the line 803, so that the whole box is electrically connected and the power cord in the multi-level electrical control box can be fully turned on.

[0031] Use alone

[0032] When individual opening is required, first return the first handle 7 to the overall closed state, so that the protrusion on the inner side of the first handle 7 is locked inside the outer shell 10. Manually push the insulating material second handle 11. The second handle 11 applies external force to the mounting part 604, and the silicone sleeve 603 on the inner wall of the mounting part 604 deforms and rotates, so that the copper connecting strip 801 on the mounting part 604 is electrically connected to the conductive plate 802, allowing individual opening. At the same time, push the second handle 11 into the fixing cap 12, so that the fixing cap 12 restricts and fixes the position of the second handle 11, ensuring that it is always in the open state, thus completing the effect of individual opening.
