[0024] Embodiment 1

[0025] like Figure 1 As shown:

[0026] An electric power grounding test device comprises a tester 1.

[0027] In this implementation scheme: the existing announcement number: CN220120902U discloses an easy-to-use power electrical grounding resistance testing device. This patent discloses a box body. The test box 21 in this application document adopts the same technical means in this prior art. This technical means will not be repeated here. For details about the improvement of this prior art, please refer to the technology disclosed below; to solve the technical problems existing in this prior art, as disclosed in the background technology above, "the device needs to frequently open and close its sealing cover when it is frequently used, which will affect the normal testing efficiency in daily work and cause project delays." In terms of combined use, this problem is obviously a real problem that is difficult to solve. In view of this, in order to solve the above problems, a flip component 2 and a limit component 3 are added on this basis.

[0028] More specifically:

[0029] like Figure 1 - Figure 4 As shown:

[0030] In combination with the above content: it also includes a flip assembly 2 arranged on one side of the tester 1, the flip assembly 2 includes a test box 21, a flip cavity 22, a guide groove 23, a pull rod 24, a counterweight 25 and a rotating shaft 26, the tester 1 and the flip cavity 22 opened on the inner surface of the test box 21 are rotationally connected, and the surface of the tester 1 and the guide groove 23 opened and slidably connected to the pull rod 24, the pull rod 24 passes through the tester 1 through the guide groove 23 and is rotationally connected to the surface of the counterweight 25 inside the flip cavity 22, the counterweight 25 is fixedly connected to the surface of the tester 1 and is also rotationally connected to the flip cavity 22, and the surface of the tester 1 is also fixedly installed with a rotating shaft 26 rotationally connected to the tester 1.

[0031] In this embodiment: when the device needs to be used, the staff needs to hold the pull rod 24 and move it to the position that needs to be tested. At this time, the limit between the tester 1 and the test box 21 can be released through the limit assembly 3, and then the test box 21 can be placed on the ground and the pull rod 24 can be released. Without the influence of the pull rod 24, the counterweight block 25 will drive the tester 1 and the rotating shaft 26 and the inside of the flip chamber 22 to rotate by its own weight. At this time, the counterweight block 25 will also drive the pull rod 24 to move along the guide groove 23 until the counterweight block 25 is located in the direction pointing to the ground. At this time, the tester 1 is rotated 180 degrees under the influence of the counterweight block 25 and faces the test box. 21, the tester 1 can be limited by the limit assembly 3 at this time, and then the detection work can be carried out by the tester 1. After use, the limiting effect of the limit assembly 3 can be released again, and the device can be directly lifted from the ground by pulling the pull rod 24. At this time, the counterweight block 25 will drive the tester 1 and the flip chamber 22 to rotate under the pull of the pull rod 24, and the pull rod 24 will move from the end of the guide groove 23 to the top of the guide groove 23 and make the panel of the tester 1 face the inside of the test box 21, and the counterweight block 25 will be on the same plane with the top surface of the test box 21 after flipping 180 degrees, thereby protecting the panel of the tester 1.

[0032] It should be noted that the density of the counterweight block 25 is relatively large, and the mass of the counterweight block 25 is greater than the mass of the tester 1. When the tester 1 and the counterweight block 25 are connected, the center of gravity of the geometric body composed of the two is located on one side of the counterweight block 25. Therefore, the counterweight block 25 can drive the tester 1 to produce a flipping motion along the axis of the rotating shaft 26 without any limit.

[0033] Going further:

[0034] In an optional embodiment, the shape of the flip chamber 22 is cylindrical.

[0035] In this embodiment, the cylindrical flipping cavity 22 can provide the tester 1 and the counterweight 25 with a stable flipping space, and the panel of the tester 1 can be flipped only by pulling the pull rod 24 .

[0036] Going further:

[0037] In an optional embodiment, the guide grooves 23 are symmetrically arranged on both sides of the surface of the tester 1 .

[0038] In this embodiment: the guide grooves 23 symmetrically arranged on both sides of the tester 1 can drive the pull rod 24 to move, and then when the pull rod 24 is pulled and the test box 21 is placed, the sliding between the guide grooves 23 and the pull rod 24 can drive the tester 1 and the counterweight block 25 to produce a flipping movement.

[0039] Going further:

[0040] In an optional embodiment, the rotating shaft 26 is circular in shape, and a circular hole matching the rotating shaft 26 is opened on the surface of the tester 1 , and the rotating shaft 26 is located on the axis of the cylinder where the flip chamber 22 is located.

[0041] In this embodiment, the position of the rotating shaft 26 enables the tester 1 and the counterweight 25 to smoothly move inside the flipping chamber 22 when rotating, thereby enabling the flipping of the tester 1 and the counterweight 25 to be realized.

[0042] Going further:

[0043] In an optional embodiment, it also includes a limit assembly 3 arranged on one side of the tester 1, the limit assembly 3 includes a accommodating bin 31 and a limit block 32, the accommodating bin 31 is fixedly mounted on the surface of the tester 1, and the inner surface of the accommodating bin 31 is also slidably connected to the limit block 32, and the surface of the limit block 32 is slidably connected to the surface of the tester 1 and the counterweight block 25.

[0044] In the present embodiment: when the tester 1 and the counterweight 25 are flipped, the limit block 32 is located inside the containing chamber 31 and does not block the flipping movement of the tester 1. After the tester 1 is flipped, the limit block 32 can slide toward the direction of the tester 1. When the two limit blocks 32 on both sides of the tester 1 slide out of the containing chamber 31, the tester 1 can stably perform the power grounding detection work. After the detection work is completed, the limit block 32 can be returned to the containing chamber 31 and the panel of the tester 1 can be directed toward the inside of the test box 21 for protection.

[0045] Going further:

[0046] In an optional embodiment, a rectangular groove matching the limiting block 32 is formed on the surface of the containing bin 31 .

[0047] In this embodiment: the rectangular groove starting from the surface of the accommodating chamber 31 can drive the limit block 32 to slide with it outside the accommodating chamber 31, so that the limit block 32 can limit the position of the tester 1 to avoid its displacement during use.

[0048] The working principle and use process of the utility model are as follows: when the device is needed, the staff needs to hold the pull rod 24 and move it to the position that needs to be tested. At this time, the limit between the tester 1 and the test box 21 can be released through the limit assembly 3, and then the test box 21 can be placed on the ground and the pull rod 24 can be released. Without the influence of the pull rod 24, the counterweight block 25 will drive the tester 1 and the rotating shaft 26 and the inside of the flip chamber 22 to rotate by its own weight. At this time, the counterweight block 25 will also drive the pull rod 24 to move along the guide groove 23 until the counterweight block 25 is located in the direction pointing to the ground. At this time, the tester 1 is rotated 180 degrees under the influence of the counterweight block 25 and faces the top surface of the test box 21. At this time, the tester 1 can be limited by the limit assembly 3, and then the test work can be carried out through the tester 1. After use, the limiting effect of the limit assembly 3 can be released again, and the device can be directly lifted from the ground by pulling the pull rod 24. Lift up, at this time the counterweight 25 will drive the tester 1 and the flip chamber 22 to rotate under the pull of the pull rod 24, and the pull rod 24 will move from the end of the guide groove 23 to the top of the guide groove 23 and make the panel of the tester 1 face the inside of the test box 21, and the counterweight 25 will be located on the same plane as the top surface of the test box 21 after flipping 180 degrees, thereby protecting the panel of the tester 1. When the tester 1 and the counterweight 25 are flipped, the limit block 32 is located inside the containing chamber 31 and does not block the flipping movement of the tester 1. After the tester 1 is flipped, the limit block 32 can slide in the direction of the tester 1. When the two limit blocks 32 on both sides of the tester 1 slide out of the containing chamber 31, the tester 1 can stably perform the power grounding detection work. After the detection work is completed, the limit block 32 can be returned to the containing chamber 31 and the panel of the tester 1 faces the inside of the test box 21 to be protected.
