[0031] Example 1

[0032] Reference Figures 1 to 8 , which is the first embodiment of the present invention, and provides a special auxiliary tool for measuring the insulation resistance of high-voltage equipment. The special auxiliary tool for measuring the insulation resistance of high-voltage equipment includes a lap rod 100, a measuring rod 200 and a grip rod 300. The grip rod 300 is arranged at the bottom, the measuring rod 200 is arranged at the head, and multiple lap rods 100 can be arranged in the middle position as needed.

[0033] Specifically, the two ends of the bridge rod 100 are respectively provided with a first engaging member 101 and a second engaging member 102, and a conductive component 103 is provided inside. The first engaging member 101 and the second engaging member 102 cooperate with each other. The conductive component 103 includes a fixed conductive member 103a and an elastic conductive member 103b provided at both ends of the bridge rod 100, and a wire 103c connecting the fixed conductive member 103a and the elastic conductive member 103b.

[0034] The electric measuring rod 200 is arranged at one end of the overlapping rod 100, and a first engaging member 101 is arranged at one end of the electric measuring rod 200;

[0035] The handle bar 300 is disposed at the other end of the lap bar 100, and a second engaging member 102 is disposed at one end thereof;

[0036] The fixed conductive member 103a and the elastic conductive member 103b are respectively disposed at one end of the electric measuring rod 200 and the handle rod 300.

[0037] Furthermore, the first engaging member 101 includes an L-shaped buckle 101a, which is arranged in an annular array at one end of the measuring rod 200 and the connecting rod 100.

[0038] The second engaging member 102 includes an engaging groove 102a, which is annularly arrayed at one end of the handle rod 300 and the overlapping rod 100, and the engaging groove 102a includes an entry groove 102a-1, a rotation groove 102a-2 and a limit groove 102a-3 that are interconnected, and the bottoms of the entry groove 102a-1, the rotation groove 102a-2 and the limit groove 102a-3 are in the same plane, and the height of the limit groove 102a-3 is higher than the height of the rotation groove 102a-2.

[0039] The fixed conductive member 103a includes a fixed carrying plate 103a-1, a first central conductive plate 103a-2 arranged in the middle position of the fixed carrying plate 103a-1, a first annular conductive plate 103a-3 that is not in contact with the first central conductive plate 103a-2, a first conductive sheet 103a-4 connected to the first central conductive plate 103a-2, and a second conductive sheet 103a-5 connected to the first annular conductive plate 103a-3.

[0040] Preferably, the first central conductive plate 103a-2 and the first annular conductive plate 103a-3 both protrude from the plane of the fixed supporting plate 103a-1, a limit ring 103a-11 is provided on the fixed supporting plate 103a-1, and the overlapping rod 100 and the measuring rod 200 are provided with a second groove 104 cooperating with the limit ring 103a-11, and a third groove 105 cooperating with the second conductive sheet 103a-5 and the second conductive sheet 103a-5.

[0041] It should be noted that the overlapping rod 100, the measuring rod 200 and the grip rod 300 are all provided with a placement groove A for placing the wire 103c. The wire 103c is arranged in the placement groove A, which can effectively prevent the wire from swinging back and forth in the rod during use, resulting in separation from the conductive sheet.

[0042] The elastic conductive member 103b includes a movable carrier plate 103b-1, a second central conductive plate 103b-2 disposed at a middle position of the movable carrier plate 103b-1, a second annular conductive plate 103b-3 not in contact with the second central conductive plate 103b-2, a third conductive sheet 103b-4 connected to the second central conductive plate 103b-2, a fourth conductive sheet 103b-5 connected to the second annular conductive plate 103b-3, a clamping conductive plate 103b-6 clamped on the bridge rod 100, a conductive spring sheet 103b-7 connected to the clamping conductive plate 103b-6, and a conductive spring sheet 103b-8 disposed on the conductive spring sheet 103b-9. 3b-7 side and fixed to the arc-shaped spring piece 103b-8 on the lapping rod 100 or the handle rod 300, and the spring 103b-9 supporting the movable carrying plate 103b-1; the conductive spring piece 103b-7 is provided with two in the lapping rod 100 and the handle rod 300, the third conductive piece 103b-4 and the fourth conductive piece 103b-5 are respectively in contact with the two conductive spring pieces 103b-7; the lapping rod 100 and the handle rod 300 are provided with a fourth groove 106 for the movable carrying plate 103b-1 to move, and the spring 103b-9 is arranged in the fourth groove 106.

[0043] Preferably, the side of the movable carrier plate 103b-1 is provided with a limiting protrusion 103b-11, and the lap rod 100 and the grip rod 300 are both provided with a sixth groove 107 for the movement of the limiting protrusion 103b-11. The lap rod 100, the electric pole 200 and the grip rod 300 are symmetrically divided into two halves, and the placement groove A and the third groove 105 are arranged on the joint surface. The two halves of the rod can be connected by a buckle in the prior art, and can be effectively combined together under the action of the first buckle 101 and the second buckle 102, so as to avoid the situation that the buckle connection is not firm and causes separation during use.

[0044] The side of the measuring rod 200 is provided with an electric contact head 201, and the end of the grip rod 300 is provided with an external plug 301. The electric contact head 201 and the external plug 301 are both connected to the wire 103c in the corresponding rod.

[0045] It should be noted that the top surface of the L-shaped clip 101a is not higher than the first annular conductive plate 103a-3 and the second conductive plate 103a-5, that is, when the first annular conductive plate 103a-3 and the second conductive plate 103a-5 are in contact with the second central conductive plate 103b-2 and the second annular conductive plate 103b-3 respectively, the L-shaped clip 101a cannot contact the movable carrier plate 103b-1. This arrangement is to ensure that the conductive plates can contact and conduct electricity.

[0046] When in use, first place the conductive component 103 in the corresponding rod, and then combine the two halves of the rod together. When docking, first move the L-shaped buckle 101a along the entry groove 102a-1 to the rotation groove 102a-2. This process requires squeezing the rod with force so that the fixed conductive component 103a pushes the movable carrier plate 103b-1 to move along the fourth groove 106. When the L-shaped buckle 101a moves to the rotation groove 102a-2, rotate the rod to rotate the L-shaped buckle 101a to the limit groove 102a-3. At this time, release the rod, and the movable carrier plate 103b-1 pushes the L-shaped buckle 101a to engage in the limit groove 102a-3 under the action of the elastic force of the spring 103b-9, and then measurement can be performed.

[0047] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, which should all be included in the scope of the claims of the present invention.
