[0019] The present invention will be further described in detail below in conjunction with the accompanying drawings, which are intended to explain the present invention rather than to limit it.

[0020] See also Figure 1 A dual-purpose insulating switch rod comprises an insulating rod group, one end of which is provided with a switch rod head 1 for operating the switch, and the other end is provided with a detachably mounted electroscope 5, and the electroscope 5 is provided with a protective structure.

[0021] The dual-purpose insulating switch rod has a pull rod head and an electric test device respectively arranged at both ends of the insulating rod group, which reasonably utilizes the end space of the insulating rod group. The electric tester is installed at the end of the insulating rod. During use, the switch is opened and closed by the pull rod at the front end of the insulating rod group to realize the power outage operation of the power line. The electric test operation of the power line can be realized after the insulating rod group is rotated for use, which solves the problem that the existing electric tester cannot be tested due to insufficient length, ensures the accuracy and safety of the electric test process, and can realize power outage and electric test by using the two ends of the insulating rod group, simplifies the operation process, and improves work efficiency. In addition, the switch rod and the electric tester are integrated on the insulating rod group to reduce the storage space, making it more convenient to carry.

[0022] The insulating rod group includes multiple insulating rods connected end to end in sequence, and two adjacent insulating rods are connected by a threaded interface to achieve rapid assembly and disassembly of the insulating rods. One end of the insulating rod is provided with an external thread, and the other end is provided with an internal thread matching the external thread. During assembly, the external thread at the front end of the first section of the insulating rod is connected to the internal thread at the end of the second section of the insulating rod. The length of the insulating rod group depends on the height of the power line.

[0023] See again Figure 1 The figure shows the structure of the first section insulating rod 2 and the last section insulating rod 3. Since the insulating rod is a hollow structure, the electroscope 5 is installed at the lower end of the last section insulating rod, and the pull rod head 1 is installed at the upper end of the first section insulating rod 2.

[0024] The electroscope 5 is installed in the last insulating rod, and its measuring end extends to the outside of the last insulating rod. The electroscope 5 is connected to the last insulating rod in a detachable manner to facilitate maintenance and replacement of the electroscope.

[0025] The electroscope 5 is connected to the last insulating rod by a threaded structure, that is, the lower end of the last insulating rod is provided with an internal thread, and the handle of the electroscope 5 is provided with an external thread matching therewith, and the two are detachably connected by the thread.

[0026] The connection between the electroscope 5 and the last section of the insulating rod can also be achieved by embedding. A rubber sleeve is provided on the handle of the electroscope to control the diameter of the handle through the rubber sleeve to match the inner diameter of the insulating rod. The handle of the electroscope is embedded in the insulating rod by interference fit to achieve a detachable connection between the two.

[0027] The connection between the electroscope 5 and the last section of the insulating rod can also be achieved by using a pin joint. A top screw is set on the outer wall of the lower end of the last section of the insulating rod, and the end of the top screw extends into the interior of the insulating rod. When the handle of the electroscope is located in the insulating rod, the top screw abuts against the handle to fix the two.

[0028] The protective structure is a protective sleeve 6 arranged at the lower end of the last insulating rod. The protective sleeve is a cylindrical structure with one end open. The protective sleeve cover is arranged on the electroscope and connected to the insulating rod. The protective sleeve is a rubber sleeve with a certain thickness. When in use, the rubber sleeve is sleeved on the electroscope from the open end, and the open end of the rubber sleeve is sleeved on the end of the last insulating rod by elastic force.

[0029] The protection level of the protective cover is IP68.

[0030] The pull rod head 1 includes a vertical rod and a horizontal rod. The vertical rod is coaxially installed on the upper end of the first section of the insulating rod, and the horizontal rod is located at the front end of the vertical rod. The two directly form an L-shaped structure. When power is supplied, the horizontal rod pushes the gate rod to rotate to achieve closing and power supply. When power is cut off, the horizontal rod extends into the pull ring of the gate rod to separate the gate rod from the knife to achieve power cut.

[0031] The electrical test is to rotate the insulating rod group so that the electrical tester is located at the top, and then the detection end of the electrical tester is overlapped with the specified position of the line and stay for a certain period of time to realize the electrical test operation.

[0032] The utility model provides a dual-purpose insulating switch rod, at the end of which an electrician is integrated, so that the insulating switch rod can not only cut off power supply, but also realize the electrician test operation, thereby increasing the use function of the insulating switch rod, improving the efficiency of power supply cut-off and electrician test operation, and shortening the operation time; in addition, the electrician is connected to the insulating rod group in a detachable manner, and a protective cover is used to continuously protect the electrician, so as to avoid damage to the electrician by external force, and also avoid daily wear of the electrician test device, thereby extending the service life of the electrician; the detachable installation method improves the efficiency of maintenance and replacement of the electrician; during the power supply cut-off process, the pull rod head 1 is responsible for the power supply cut-off operation of the power line, and can be quickly switched to the test operation by rotating the insulating rod group. The invention can be used as an electrical device to perform electrical testing operations, which effectively avoids the problems of the existing electrical testing device's rod body touching, shrinking and insufficient length, thereby ensuring the accuracy and safety of the electrical testing process. It is particularly suitable for work needs in complex environments such as high-position electrical testing. The insulating rod group adopts a splicing assembly method, which can make the insulating pull-switch rod suitable for different environments and meet the needs of different work scenes, so that operators can better complete operations in various complex work scenes; finally, the electrical tester is integrated on the insulating pull-switch rod to form a multi-functional power tool, and the insulating tube group is used to replace the telescopic rod of the existing electrical tester, which reduces the cost of power maintenance tools.
