摘要：【中文】本发明涉及绝缘拉杆及快速开关。快速开关包括断口和操动机构，断口与操动机构之间设有绝缘拉杆，绝缘拉杆包括绝缘管，绝缘管的一端连接有第一接头组件，另一端连接有第二接头组件，第一、第二接头组件均包括管状接头，管状接头上设有径向凸环，绝缘管插套粘接在管状接头上且被径向凸环所挡，绝缘管上还插套粘接有衬套。绝缘管的外表面与管状接头粘接，内表面与衬套粘接，这样就增加了绝缘管与接头连接位置处的整体厚度，当绝缘拉杆受到较大冲击力时，绝缘管需克服管状接头及衬套的作用力才有可能发生变形，从而在很大程度上降低了绝缘管受到较大冲击力而发生径向变形的可能。 【EN】The invention relates to an insulating pull rod and a quick switch. The quick switch comprises a fracture and an operating mechanism, an insulating pull rod is arranged between the fracture and the operating mechanism and comprises an insulating tube, one end of the insulating tube is connected with a first joint component, the other end of the insulating tube is connected with a second joint component, the first joint component and the second joint component respectively comprise a tubular joint, a radial convex ring is arranged on the tubular joint, an insulating tube plug bush is bonded on the tubular joint and is blocked by the radial convex ring, and a bushing is bonded on the insulating tube. The outer surface of the insulating tube is bonded with the tubular joint, and the inner surface of the insulating tube is bonded with the lining, so that the overall thickness of the connecting position of the insulating tube and the joint is increased, when the insulating pull rod is subjected to a large impact force, the insulating tube is likely to deform only by overcoming the acting force of the tubular joint and the lining, and the possibility of radial deformation of the insulating tube due to the large impact force is reduced to a great extent.
