Description

Technical Field

[0001] The utility model relates to the technical field of emergency rescue, in particular to an electric tester for emergency rescue. Background Art

[0002] Urban waterlogging is an inevitable major problem in southern coastal cities or areas with developed water systems, involving urban water supply and drainage projects, traffic arteries, hydrology and water resources projects, urban water conservancy projects and many other aspects. In the process of urban waterlogging rescue operations, since urban power facilities are spread all over the place, the power facilities may accidentally injure rescue workers and passers-by through the water medium during waterlogging. In order to avoid electric shock, before carrying out rescue operations on flooded roads, the tip of the tester should be touched to the water surface to ensure safety before carrying out rescue operations.

[0003] Existing electric testers are basically household or industrial electric testers. When in use, workers need to hold the electric testers close to the charged medium for contact. In flood rescue operations, it is often thunderstorm weather, and the ground is wet or waterlogged. Since the length of the pen cannot be adjusted, workers need to wade through water when testing electricity, which makes it impossible to guarantee the safety of rescue workers. At the same time, the electric tester cannot provide lighting, which brings inconvenience to workers when rescuing at night.

[0004] According to the publication number: CN204495895U, a test pen is provided, which includes a probe, an electric pen body, a cap, and a lower lamp cap, a transparent lamp tube, a neon lamp, a safety resistor and an upper lamp cap which are sequentially loaded into the electric pen body. The characteristics are: the electric pen body is composed of an upper pen body, an intermediate pen body and a lower pen body. The intermediate pen body is made of transparent material, and its position corresponds to the position of the neon lamp. The intermediate pen body is injected once and then injected twice with the upper and lower pen bodies. The outer circle of the intermediate pen body after injection molding and the upper and lower pen bodies is provided with a protrusion or a concave hole; the lower pen body is provided with a bottom extending and wrapping the outside of the probe, and the exposed length of the probe is not more than 2cm. The probe and the lower pen body are injection molded together. The utility model has a novel structure, beautiful appearance, reduces costs, and has a good ability to prevent the probe from rotating.

[0005] According to the above-mentioned electric tester, since the length of the pen shaft cannot be adjusted, the staff needs to wade through water when measuring electricity, which makes the safety of the rescue personnel unable to be guaranteed. At the same time, the electric tester cannot be illuminated, which causes inconvenience to the staff during rescue at night. Therefore, we need to propose an electric tester for emergency rescue.

[0025] When measuring electricity, the metal head 2 is pulled to drive the rod body 1 and the conductive component 7 to move, so that the length of the rod body 1 and the conductive component 7 can be adjusted. Then the staff takes the rod body 1 and inserts the metal head 2 into the accumulated water to measure electricity.

The inner cavity of the first movable tube 12 is plugged and slid with the surface of the second movable rod. The second movable rod is moved by pulling the metal head 2, so that the second movable rod is moved to the end of the first movable rod for fixation, and then the first movable rod is moved upward to the end of the fixed rod for fixation, so that the length of the rod body 1 is extended.

[0027] The lighting assembly 3 includes an LED lighting lamp 31 and a back cover 32. The LED lighting lamp 31 is electrically connected to the circuit control board 5. The LED lighting lamp 31 is installed at the bottom end of the back cover 32. The top end of the back cover 32 is threaded.
