[0025] Example one: please refer to Figures 1-4 The utility model provides a kind of technical scheme: a kind of electric insulating operating rod applied to moulded case circuit breaker opening and closing, including insulating sleeve rod 1 and insulating operating rod 2, insulating operating rod 2 is limited to be inserted in the top end inside of insulating sleeve rod 1.

[0026] The bottom end of the both sides of insulating operating rod 2 is limited to slide and install limiting block 3, specifically, the bottom end of the both sides of insulating operating rod 2 is equipped with limiting groove 16, limiting block 3 is slidably installed in limiting groove 16, spring 17 is fixedly connected in the inside of limiting groove 16, the other end of spring 17 is fixedly connected with limiting block 3.Limiting groove 16 is slidably installed with moving rod 18, the other end of moving rod 18 is fixedly connected with limiting block 3.Spring 17 is sleeved on the outside of moving rod 18.

[0027] The end of limiting block 3 away from insulating operating rod 2 is fixedly connected with connecting rod 4, the other end of connecting rod 4 is fixedly connected with adjusting block 5, a plurality of limiting holes 6 are evenly provided on the position of the both sides of insulating sleeve rod 1 corresponding limiting block 3, limiting block 3 is inserted and matched with limiting hole 6, and the position of the both sides of the sidewall of insulating sleeve rod 1 corresponding limiting hole 6 is provided with communication hole 7.

[0028] The outer surface of adjusting block 5 is fixedly connected with several anti-skid bosses. By setting anti-skid boss, the friction when operating adjusting block 5 can be improved.

[0029] The top end of insulating operating rod 2 is fixedly installed with vertical plate 8, the top end of vertical plate 8 is fixedly connected with horizontal plate 9, and the upper end surface of horizontal plate 9 is provided with arc-shaped groove 10.Vertical plate 8 and horizontal plate 9 enter the inside of moulded case circuit breaker, and the inside switch contact of moulded case circuit breaker is hung by horizontal plate 9, to control the opening and closing of moulded case circuit breaker.

[0030] An installation base 11 is fixedly installed on the top outer side of the insulating sleeve rod 1, and a spotlight ring 12 is fixedly installed on the upper surface of the installation base 11. A controller is provided at the bottom end of the insulating sleeve rod 1 near the handle 14. The controller is electrically connected to the spotlight ring 12, and the opening and closing of the spotlight ring 12 can be controlled by the controller to provide lighting and ensure the smooth implementation of related operations.

[0031] The outer side of the insulating sleeve rod 1 is marked with scale lines 13 corresponding to the positions of the limiting holes 6. By observing the scale lines 13, the extension length of the insulating operating rod 2 can be determined.

[0032] Furthermore, a handle 14 is fixedly connected to the bottom end of the insulating sleeve rod 1, and a hanging ring 15 is fixedly connected to the bottom end of the handle 14. The hanging ring 15 can be used to hang it on a hook on the wall, thus facilitating storage.

[0033] Working principle:

[0034] When adjusting the extension length of the insulating operating rod 2, the operator holds the outside of the insulating sleeve rod 1 with their thumb and forefinger, pinching the adjusting blocks 5 on both sides. Moving the adjusting blocks 5 closer together causes the limiting block 3 to disengage from the limiting hole 6, allowing the limiting block 3 to move into the limiting groove 16. This causes the spring 17 to contract. When the connecting rod 4 moves into the limiting hole 6, the operator pushes the adjusting blocks 5 upwards, causing the connecting rod 4 to move upwards through the connecting hole 7. This, in turn, moves the insulating operating rod 2 upwards, extending it out of the insulating sleeve rod 1. After extending to the appropriate position, the operator releases the adjusting blocks 5, allowing the spring 17 to return to its original position and move the adjusting blocks 5 away from each other, causing the limiting block 3 to enter the limiting hole 6, thus limiting the position of the limiting block 3. This method extends the insulating operating rod 2, making operation convenient and safe. It is suitable for operating air switches in floor cabinets, electrical boxes, outdoor distribution boxes, and outdoor transformer substations. It is simple and efficient to operate, thus improving work efficiency.

[0035] The circuit breaker is accessed via the vertical plate 8 and the horizontal plate 9. The horizontal plate 9 is used to hold the internal switch contacts of the circuit breaker, thereby controlling its opening and closing. A controller is installed at the bottom of the insulating sleeve rod 1 near the handle 14. The controller is electrically connected to the spotlight ring 12, and can control the opening and closing of the spotlight ring 12 to provide lighting and ensure the smooth implementation of related operations.

[0036] Example 2: Figure 5 As shown, the difference between this embodiment and Embodiment 1 is that, to improve the safety of low-voltage power transmission operation, a transparent protective cover 19 is fixedly installed on the bottom end of the handle 14 near the insulating sleeve 1, and the handle 14 is made of insulating material. This further improves the safety of the device.

[0037] The utility model embodiment makes the detailed explanation in combination with the drawing, but the utility model is not limited to the above -mentioned embodiment, still can make various changes in the knowledge range of ordinary skill in the art person who has possessed under the premise of not departing from the utility model tenet.
