[0047] See also Figure 1-Figure 5 As shown, this embodiment provides an isolating switch operating rod, including an operating head 1, a connecting sleeve 2 and a handle rod 3;

[0048] Along the axial direction of the handle bar 3, the handle bar 3 includes a corresponding first end and a second end;

[0049] The connecting sleeve 2 is connected to the first end, and the operating head 1 is detachably connected to the connecting sleeve 2.

[0050] During operation, the operator needs to hold the handle rod to make the operating head complete the safe operation of pulling and closing the low-voltage disconnector of the outdoor distribution box. When operating operating mechanisms of various types of interfaces, it is only necessary to remove the operating head from the connecting sleeve and replace it with a suitable operating head, and connect the suitable operating head to the connecting sleeve for operation.

[0051] To sum up, the operating rod of the isolating switch provided in this embodiment is detachably connected through the operating head and the connecting sleeve to facilitate the replacement of different types of operating heads. The operator only needs to be equipped with different types of operating heads, which are connected to the connecting sleeves through different types of operating heads to adapt to operating mechanisms of different types of interfaces, thereby improving the versatility of the isolating switch operating rod, thereby saving costs to a certain extent, and the operating head is small in size, so it is easy to carry, which solves the technical problems of inconvenient use and high cost of the operating rod of the isolating switch in the prior art.

[0052] Preferably, see Figure 2 and Figure 3 As shown, a card slot is provided on the connecting sleeve 2 of this embodiment;

[0053] The operating head 1 is provided with a protrusion 11;

[0054] The protrusion 11 is inserted into the slot, and the protrusion 11 and the connecting sleeve 2 are connected via a pin 4 .

[0055] The protrusion is inserted into the slot to allow the connecting sleeve to limit the operating head, making the connection between the operating head and the connecting sleeve more reliable and accurate, and connected by a pin shaft to further improve the firmness of the connection and prevent the operating head from falling off during operation by the operator.

[0056] Preferably, see Figure 2 and Figure 3 As shown, the connecting sleeve 2 of this embodiment is provided with a first clamping hole, and the first clamping hole is connected with the clamping slot;

[0057] The protrusion 11 is provided with a second clamping hole;

[0058] The pin shaft 4 is inserted into the first clamping hole and the second clamping hole in sequence.

[0059] When the operating head needs to be replaced, the pin shaft is pulled out from the second clamping hole and the first clamping hole, and the protrusion of the operating head is pulled out from the clamping groove of the connecting sleeve, so that the operating head can be disassembled, the operation is convenient, and the operation efficiency is improved.

[0060] Preferably, see Figure 2 and Figure 3 As shown, the isolating switch operating rod described in this embodiment further includes a pin sleeve 5;

[0061] The pin sleeve 5 is fixedly connected to the connecting sleeve 2;

[0062] The pin sleeve 5 is provided with a third clamping hole, and the axis of the third clamping hole coincides with the axis of the first clamping hole;

[0063] Along the axial direction of the pin shaft 4, the pin shaft 4 has a corresponding third end and a fourth end;

[0064] The fourth end passes through the third clamping hole and the second clamping hole in sequence, and is connected to the pin sleeve 5 through the elastic member 6;

[0065] The third end is clamped on the pin sleeve 5;

[0066] The elastic member 6 allows the pin shaft 4 to always have a tendency to move along the axial direction from the third end to the fourth end.

[0067] The elastic member enables the pin shaft to always have a tendency to move from the third end to the fourth end along the axial direction, and the third end is clamped on the pin sleeve, so that the pin shaft is always tightly inserted in the second clamping hole and is not easy to disengage, thereby ensuring that the operating head is always tightly connected to the connecting sleeve and is not easy to disengage from the connecting sleeve, thereby ensuring the stability of the operator's operation.

[0068] Preferably, see Figure 1 and Figure 3 As shown, the pin sleeve 5 of this embodiment is provided with a limiting groove;

[0069] The third end of the pin shaft 4 is provided with a clamping portion, and the clamping portion is clamped in the limiting groove.

[0070] The third end of the pin shaft is clamped on the pin sleeve.

[0071] When the operating head needs to be replaced, the clamping part is pulled by hand to make the clamping part overcome the preload force of the elastic member and move from the fourth end to the third end, so that the pin shaft is disengaged from the second clamping hole. At this time, the operating head can be taken out of the clamping slot, thereby realizing the disassembly of the operating head.

[0072] Preferably, see Figure 5 As shown, the clamping portion in this embodiment is a pull ring 7.

[0073] The pull ring 7 facilitates the operator to pull the pin shaft outwards, further improving the convenience of operation.

[0074] Optionally, the elastic member is a spring or a spring.

[0075] Preferably, the handle bar is made of insulating material;

[0076] Alternatively, the handle bar is coated with insulating material.

[0077] The operator must not exceed the range of the insulating material during operation, which makes the operation safety of the isolating switch operating rod good and can effectively protect the personal safety of the operator.

[0078] Preferably, see Figure 1 and Figure 4As shown, the isolating switch operating rod described in this embodiment further includes a plug 8;

[0079] A cavity is provided in the handle bar 3;

[0080] Along the extension direction of the cavity, one end of the cavity passes through the handle rod 3 and forms an opening at the second end;

[0081] The plug 8 is inserted into the opening.

[0082] In the prior art, the operating rod of the isolating switch is inconvenient to use because the handle rod is too heavy.

[0083] The isolating switch operating lever provided in this embodiment has a cavity formed on the handle bar, and the cavity can reduce the weight of the handle for easy operation.

[0084] In addition, the cavity can also be used to place other tools that are inconvenient to carry, thereby making the isolating switch operating rod more practical.

[0085] Preferably, see Figure 2 As shown, a connecting groove is provided on the connecting sleeve of this embodiment, and the handle rod is inserted into the connecting groove and connected to the connecting sleeve by rivets.

[0086] The handle rod is inserted into the connecting groove and connected by rivets, so that the connection between the handle rod and the connecting sleeve is more firm and reliable, and the operator is prevented from falling off the connecting sleeve from the handle rod during operation.
