DETAILED DESCRIPTION

[0016] The utility model will be further explained in detail through specific implementation ways as follows:

[0017] As Figure 1 , Figure 2 and Figure 4 The utility model embodiment proposes an electroscope and grounding wire integrated device, including grounding hook 1, the electroscope 2 of connecting in the outer one side of grounding hook 1, the insulating rod 4 connected with the grounding hook 1 through connecting structure 3 and the telescopic holding rod 5 connected with the insulating rod 4, the insulating rod 4 is connected with telescopic holding rod 5 one end on the length of storage cavity 6 along its axial direction, and the telescopic holding rod 5 one end sliding limit is located in storage cavity 6, and the length of storage cavity 6 is not less than the length of telescopic holding rod 5 in the shortest contraction state.

[0018] The electroscope and grounding wire integrated device before use:

[0019] The telescopic holding rod 5 is removed from storage cavity 6, and then the telescopic holding rod 5 is lengthened to the required length (such as Figure 2Then, the voltage detector 2 can be used to perform voltage testing, and the grounding hook 1 can be used to perform grounding.

[0020] When this integrated voltage testing and grounding device needs to be stored after use:

[0021] Retract the telescopic grip 5 to its shortest retracted state, then slide the telescopic grip 5 into the storage cavity 6 for storage (e.g., Figure 1 ).

[0022] This integrated voltage testing and grounding device forms a storage cavity 6 inside the insulating rod 4, and the length of the storage cavity 6 is not less than the length of the telescopic grip rod 5 in its shortest retracted state. This allows the telescopic grip rod 5 to be retracted to its shortest retracted state and then slid into the storage cavity 6 for complete storage. This shortens the relative length of the integrated voltage testing and grounding device in the stored state, making it convenient to carry outdoors.

[0023] In this embodiment, the length of the storage cavity 6 is exactly equal to the length of the telescopic grip rod 5 when it is in its shortest retracted state, so the storage cavity 6 can completely store the telescopic grip rod 5.

[0024] It should be noted that the shortest contracted state is the state when the telescopic grip rod 5 is contracted to its shortest length.

[0025] To ensure stability of the telescopic grip 5 during use or storage; such as Figure 1 , Figure 2 as well as Figure 4 As shown, according to another embodiment of the present invention, in the integrated device for testing and grounding wires, the end of the insulating rod 4 connected to the telescopic gripping rod 5 is provided with a locking member 7 for locking or unlocking the telescopic gripping rod 5.

[0026] In this embodiment, the locking member 7 can be a locking bolt; rotating the locking bolt adjusts its contact with the telescopic grip rod 5, thereby locking or unlocking the telescopic grip rod 5.

[0027] Specifically, before using this integrated voltage detection and grounding device:

[0028] Remove the telescopic grip rod 5 from the storage cavity 6. With one end of the telescopic grip rod 5 confined within the storage cavity 6, rotate the locking bolt to abut against the telescopic grip rod 5, thus maintaining a stable state between the telescopic grip rod 5 and the insulating rod 4 (a groove can be opened on the side wall of the end of the telescopic grip rod 5 confined within the storage cavity 6, and one end of the locking bolt is threaded into this groove to improve stability when locking). Then, grasp the other end of the telescopic grip rod 5 to extend it to the required length. The voltage detector 2 can then be used for voltage testing, and the grounding hook 1 can be used for grounding.

[0029] Specifically, when the electricity testing and grounding wire integrated device needs to be stored after use:

[0030] The telescopic holding rod 5 is retracted to the shortest retracted state, and then the locking bolt is reversely rotated to disengage from the telescopic holding rod 5. At this time, the telescopic holding rod is slid into the storage cavity 6, and then the locking bolt is rotated to abut against the telescopic holding rod 5. The telescopic holding rod 5 is stably stored in the storage cavity 6.

[0031] Further, the end of the telescopic holding rod 5 away from the insulating rod 4 is also connected with a handle 8. The diameter of the end of the handle 8 connected with the telescopic holding rod 5 is greater than the diameter of the cavity opening of the storage cavity 6, so that the handle 8 cannot be slid into the storage cavity 6. The handle 8 not only facilitates the user to hold when in use, but also limits the position during the process of sliding the telescopic holding rod 5 into the storage cavity 6.

[0032] The connecting structure 3 will be further described below. As shown in Figure 1 , Figure 2 and Figure 5 , according to another embodiment of the present application, the connecting structure 3 comprises a connecting cylinder 31 and a threaded connecting rod 32. One end of the connecting cylinder 31 is connected with the insulating rod 4, and one end of the threaded connecting rod 32 is connected with the grounding hook 1 and the other end is screwed into the connecting cylinder 31.

[0033] In the present application, the connecting cylinder 31 and the threaded connecting rod 32 are used to stably connect the grounding hook 1 and the insulating rod 4 together.

[0034] In order to further improve the stability of the connection between the grounding hook 1 and the insulating rod 4, the connecting structure 3 further comprises a positioning reinforcing head 33 and a positioning groove. The positioning reinforcing head 33 is arranged in one end of the connecting cylinder 31 connected with the insulating rod 4. The positioning groove is arranged on the end of the threaded connecting rod 32 away from the grounding hook 1 and is used for embedding the positioning reinforcing head 33 to cooperate.

[0035] In the present embodiment, the positioning reinforcing head 33 is integrally formed with the connecting cylinder 31. When the connecting cylinder 31 and the threaded connecting rod 32 are connected, the threaded connecting rod 32 is rotated and moved into the connecting cylinder 31 until the threaded connecting rod 32 abuts against the connecting cylinder 31 and the positioning reinforcing head 33 is completely embedded in the positioning groove, so as to improve the connection stability of the grounding hook 1 and the insulating rod 4.

[0038] The first perforation and the second perforation can each be formed with an internal thread connected with the thread of the grounding wire 10 connector 9 to improve the connection stability of the grounding wire 10 connector 9.

[0039] Due to the connection design of the grounding wire 10 connector 9, the threaded connecting rod 32 and the connecting cylinder 31 can be connected by sliding instead of by threading, and the threaded connecting rod 32 and the connecting cylinder 31 can be stably connected, and at this time, the connection or disconnection between the threaded connecting rod 32 and the connecting cylinder 31 is more convenient.

[0040] The insulating rod 4 outer wall can further be rotatably connected with a take-up reel 11, and when the electric testing and grounding wire integrated device is stored, the grounding wire 10 is wound on the take-up reel 11 for storage.

[0046] Based on the above scheme:

[0047] One end of the ground wire 10 connecting head 9 is provided with a mounting groove in the axial direction thereof, and a plurality of mounting holes are arranged in a scattered manner outside the mounting groove. One end of each mounting hole is in communication with the mounting groove, and the other end of each mounting hole extends to the inner wall of the connecting ring 12; the adjustable locking part 13 comprises a mounting adjusting column 131 and a locking column 132.
