[0038] In order to enable the above-mentioned purpose, features and advantages of the present utility model to be more clearly understood, the scheme of the present utility model will be further described below.

[0039] In the following description, many specific details are set forth in order to provide a thorough understanding of the present utility model, but the present utility model can also be implemented in other ways different from those described herein; obviously, the examples in the specification are only some of the embodiments of the present utility model, not all the embodiments.

[0040] The electroscope of the present utility model embodiment will be described below in conjunction with the accompanying drawings.

[0041] As Figures 1-6 shown, the electroscope of the present utility model embodiment can include an electroscope body 1, a guard ring 2, an inductor 3, a warning component 4, a controller 6 and a battery 7.

[0042] The electric tester body 1 is internally provided with a cavity 100, and a guard ring 2 is arranged on the electric tester body 1, and at least one inductor 3 is arranged on the guard ring 2, and the inductor 3 is used for detecting the position of the hand of the operator, wherein the inductor 3 can be multiple, and the multiple inductors 3 are distributed in an equiangular circumferential array on the guard ring 2, and this layout mode can construct a multi-angle detection mechanism, thereby effectively expanding the detection range and significantly improving the accuracy of detecting the position of the hand of the operator.

[0043] It should be noted that the type of inductor 3 is diverse, which can be one of an infrared sensor, a proximity sensor or a photoelectric sensor, and a combination of multiple types can also be used according to actual needs. It can be flexibly determined according to actual conditions, which is not specifically limited here.

[0044] The warning component 4 is arranged in the cavity 100, which is used to issue a warning signal to remind the operator of the existence of non-standard operation behavior, wherein the warning component 4 is a buzzer or a sound-light alarm, which can be selected according to actual conditions.

[0045] For example, if the warning component 4 is a buzzer, the operator is reminded to adjust and standardize the operation in time by relying on the rapid buzzing sound.

[0046] The normally open switch 5 is arranged on the guard ring 2, which is used to control the start and stop of the electric tester body 1, the inductor 3, the warning component 4 and the controller 6, wherein the normally open switch 5 refers to a switch whose contact points are in a disconnected state and the circuit is not connected when it is not subjected to external force, so the operator needs to hold the electric tester body 1 by hand and continuously press the normally open switch 5 by the thumb or other fingers, only in this way, the contact points of the normally open switch 5 can be continuously closed, thereby making the electric tester body 1, the inductor 3, the warning component 4 and the controller 6 maintain the energized state. This design not only ensures the continuous operation of the electrical components, but also limits the position of the operator's hand, making the operation more standardized and safe, and further limiting the non-standard operation of the operator.

[0047] The controller 6 and the battery 7 are arranged in the cavity 100 respectively, the electric tester body 1, the inductor 3, the warning component 4 and the controller 6 are connected with the normally open switch 5 respectively, the battery 7 is connected with the normally open switch 5, and the controller 6 is connected with the warning component 4 and the inductor 3 respectively, wherein the battery 7 can be a lithium battery, and the controller 6 is a programmable PLC (Programmable Logic Controller) controller.

[0048] Specifically, in actual operation scenarios, the operator needs to hold the tester for operation. In specific operation, the operator needs to hold the tester body 1 with hands and continuously press the normally open switch 5 with the thumb or other fingers. At this time, the tester body 1, the inductor 3, the warning component 4 and the controller 6 will be powered on and started. In order to ensure that the tester body 1 can continuously perform detection work in the powered-on state, the operator must continuously press the normally open switch 5 with the hand, which also limits the one arm of the operator and effectively restricts the arm, thereby preventing the arm from crossing the guard ring 2 during operation.

[0049] In addition, in another case, if the operator needs to hold and lift the tester with both hands during a long time of work because he feels difficult to lift the tester with one arm, the situation is different. That is, when the other arm holds the tester body 1 to form a double-handed lifting, if the position of the arm crosses the guard ring 2 due to non-standard, the inductor 3 will immediately sense and detect the position change of the arm, and then rapidly send the signal to the controller 6. After receiving the signal, the controller 6 will immediately control the warning component 4 to issue a warning signal to remind the operator that there is a non-standard operation behavior at present.

[0050] Therefore, the tester can restrict and remind the operator of non-standard behavior during the test, thereby reducing the interference to the electric field, ensuring the accuracy of the detection result, and reducing the risk of electric shock.

[0051] In an embodiment of the present application, as shown in Figure 3 The tester can further include a triggering mechanism 8, and the triggering mechanism 8 includes a squeezing ring 80, a plurality of limiting rods 81 and a plurality of springs 82.

[0052] The guard ring 2 is provided with a plurality of limiting holes 21, and the plurality of limiting rods 81 are arranged one by one corresponding to the plurality of limiting holes 21. One end of the limiting rod 81 is elastically connected to the limiting hole 21 through the spring 82, and the other end of the limiting rod 81 extends out of the limiting hole 21 and is connected to the squeezing ring 80. The squeezing ring 80 is sleeved outside the tester body 1 and can move to press the normally open switch 5 relative to the tester body 1, so as to control the tester body 1, the inductor 3, the warning component 4 and the controller 6 to start running.

[0053] In the above scheme, the squeezing ring 80 can increase the contact area between the hand holding and the normally open switch 5. In this way, the operator does not need to press the normally open switch 5 with the thumb intentionally, but only needs to let the fist surface of the thumb and the fingers naturally touch the squeezing ring 80 when holding, so as to realize the pressing operation of the normally open switch 5. This improvement not only simplifies the operation action, but also greatly improves the comfort during the process of squeezing the normally open switch 5 with the hand.

[0054] Further, the scheme also introduces the ingenious combination of the limiting rod 81 and the spring 82. One end of the limiting rod 81 is connected in the limiting hole 21 through the spring 82, and such design makes the limiting rod 81 extrude the spring 82 correspondingly when the operator extrudes the normally open switch 5. When the electric test is finished and the operator releases the extrusion on the extrusion ring 80, the spring 82 will push the limiting rod 81 to drive the extrusion ring 80 to automatically move away from the normally open switch 5 due to the potential energy generated by the deformation, so as to quickly release the extrusion state of the normally open switch 5. Meanwhile, the close cooperation of the limiting rod 81 and the limiting hole 21 provides stable limiting effect for the extrusion ring 80 in the moving process, and ensures the stability of the extrusion ring 80 in the moving process.

[0055] In an embodiment of the present application, as shown in Figure 1 The electric tester body 1 comprises an insulating rod 10, an extension rod 11, an indicator 12 and a probe 13.

[0056] The insulating rod 10, the extension rod 11, the indicator 12 and the probe 13 are assembled together from bottom to top.

[0057] In the above scheme, the insulating rod 10 serves as a holding part, the length of the electric tester can be adjusted by pulling the extension rod 11, the indicator 12 is used for displaying whether the object is electrified, when contacting the electrified object, the indicator will obviously change, such as emitting light, making sound or deflecting the pointer, so as to remind the user. The probe 13 is used for directly contacting the object to be tested, and the insulating rod 10, the extension rod 11, the indicator 12 and the probe 13 are all prior art, which will not be described in detail here.

[0058] The insulating rod 10 is internally provided with a cavity 100, the cavity 100 is provided with a first opening 101, and part of the warning component 4 is exposed to the first opening 101, so that the operator can timely observe the alarm prompt of the warning component 4, for example, the warning component 4 is an audible and visual alarm, and the operator can be reminded by flashing light.

[0059] The guard ring 2 is arranged on the insulating rod 10, and the hand of the operator cannot exceed the guard ring 2, so that the hand of the operator is held on the insulating rod 10.

[0060] The indicator 12 is connected with the normally open switch 5, so that when the electric test is needed, the indicator 12 can be turned on only by pressing the normally open switch 5, and therefore the hand of the operator must be pressed on the extrusion ring 80, so that the position of the hand is restricted, and the non-standard operation is reduced.

[0061] In an embodiment of the present application, as shown in Figure 4 and Figure 5As shown, the electric tester further comprises a first shielding cover 90, the first shielding cover 90 is sleeved on the insulating rod 10, and one end of the first shielding cover 90 is fixedly connected with the indicator 12, and the other end of the first shielding cover 90 extends until covering the guard ring 2 and the extrusion ring 80.

[0062] In the above scheme, the first shielding cover 90 can cover the guard ring 2 during use, thereby forming covering protection for the inductor 3, which plays a role in blocking dust on the one hand, ensures the accuracy of the inductor 3, and plays a protective role on the other hand, and in the case of accidental falling of the electric tester, the first shielding cover 90 can significantly reduce the impact on the inductor 3, and avoid damage due to collision.

[0063] In addition, during electric testing, with the extension of the telescopic rod 11, the indicator 12 will drive the first shielding cover 90 away from the guard ring 2, thereby removing the protection state of the guard ring 2 and the inductor 3 inside the guard ring 2. In this way, the inductor 3 can be smoothly exposed, fully exerting its detection function, and ensuring the smooth progress of electric testing.

[0064] Further, as shown in Figure 4 and Figure 6 , the first shielding cover 90 comprises a first sleeve 900 in the shape of a circular truncated cone and a second sleeve 901 in the shape of a cylinder, wherein the first sleeve 900 and the second sleeve 901 are integrally formed, one end of the first sleeve 900 is fixed with the indicator 12, and the second sleeve 901 covers the guard ring 2 and the extrusion ring 80.

[0065] In the above scheme, the first sleeve 900 in the shape of a circular truncated cone is convenient to be fixedly connected with the indicator 12, and the second sleeve 901 in the shape of a cylinder can expand the accommodating opening, thereby facilitating covering of the guard ring 2.

[0066] In an embodiment of the present application, as shown in Figure 5 and Figure 6 , the electric tester further comprises a second shielding cover 91, the second shielding cover 91 is sleeved outside the indicator 12, one end of the second shielding cover 91 is threadedly connected on the first shielding cover 90, and the other end of the second shielding cover 91 extends to cover the probe 13.

[0067] In the above scheme, the second shielding cover 91 can shield and cover the probe 13 and the indicator 12, and in the case of accidental falling of the electric tester, the second shielding cover 91 can significantly reduce the impact on the probe 13 and the indicator 12, and avoid damage of the probe 13 and the indicator 12 due to collision, thereby improving the service life of the electric tester.

[0068] Further, as shown in Figure 6As shown, the second shielding cover 91 is provided with a circular truncated cone-shaped threaded hole 910 and a second opening 911, and the diameter of the threaded hole 910 away from the hole of the second sleeve 901 and the diameter of the second opening 911 are both larger than the diameter of the indicator 12, the threaded hole 910 is matched with the first sleeve 900, the threaded hole 910 is provided with an internal thread, and the outer wall of the first sleeve 900 is provided with an external thread matched with the internal thread.

[0069] In the above scheme, by rotating the second shielding cover 91, the first sleeve 900 and the threaded hole 910 can be threadedly connected. This design enables the second shielding cover 91 to stably cover the probe 13 and the indicator 12, providing effective protection for them. When the electrostatic test operation is needed, the second shielding cover 91 can be easily removed by reversing the rotation of the second shielding cover 91, so that the probe 13 and the indicator 12 are exposed, facilitating the electrostatic test operation.

[0070] In addition, the threaded hole 910 away from the second sleeve 901 and the diameter of the second opening 911 are both designed to be larger than the diameter of the indicator 12. Such a design ensures that the second shielding cover 91 will not be hindered by the indicator 12 during removal, so that it can be smoothly removed from the electrostatic tester body 1, further improving the convenience and efficiency of operation.

[0071] In an embodiment of the present application, as shown in Figure 1 The guard ring 2 is provided with a plurality of grooves 20, and each inductor 3 is embedded in a corresponding groove 20.

[0072] In the above scheme, the grooves 20 provide physical barriers for the inductors 3, preventing them from being damaged when subjected to external impact or collision. Meanwhile, the embedded design of the inductors 3 can make the overall design of the electrostatic tester more compact, making the appearance of the electrostatic tester more neat and beautiful.

[0073] In summary, the electrostatic tester of the embodiments of the present application can constrain and remind the operator of non-standard behavior during the electrostatic test, thereby reducing the interference with the electric field, ensuring the accuracy of the detection results, and reducing the risk of electric shock.
