Description

Technical Field

[0001] This utility model relates to the field of testing instruments, and in particular to an insulation testing instrument. Background Technology

[0002] New energy vehicles refer to automobiles that use unconventional vehicle fuels as their power source and integrate advanced technologies in vehicle power control and drive, resulting in vehicles with advanced technical principles, new technologies, and new structures. New energy vehicles include pure electric vehicles, range-extended electric vehicles, hybrid electric vehicles, fuel cell electric vehicles, hydrogen engine vehicles, and other new energy vehicles. With social development, the application of new energy vehicles is becoming more and more widespread, and therefore, the demand for insulation testing instruments for new energy vehicles is increasing day by day.

[0003] For example, Chinese Patent Publication No. CN220154573U discloses an insulation tester for new energy vehicles, comprising a handheld testing mechanism and a vehicle shell adsorption mechanism. The handheld testing mechanism includes a current conducting component connected directly above the tester, and the current conducting component includes a magnetic pole guide that can be magnetically attracted and fixed to electronic devices inside the vehicle. The vehicle shell adsorption mechanism includes an adsorption component connected to the tester and a grounding component connected within the adsorption component. Alternatively, two sets of vertically distributed brackets are mounted on the outside of a conventional tester using fixing nuts, and a vacuum fixing component that can be adsorbed onto the outside of the vehicle shell is spirally connected within the brackets.

[0004] However, in the above solution, it is not convenient to rewind the wire after the device is used. During the wire rewinding process, the wire is easily tangled and knotted, which affects the detection efficiency. Utility Model Content

[0005] This invention provides an insulation tester to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] An insulation tester includes a test box with a test instrument embedded in its side wall. A winding cavity is provided inside the test box, and two winding tubes are rotatably connected to the inner side wall of the winding cavity via bearings. The two winding tubes share a winding structure on their side walls. A pen slot is provided at the top of the test box, in which a test pen is placed. A clamping slot is also provided at the top of the test box, in which a test clamp is placed. One end of each of the test pen and the test clamp is provided with a wire. One end of each wire passes through the side wall of the test box and is slidably connected to it. The two wires are respectively wound around the outer side wall of the two winding tubes, with one end of each wire passing through the side wall of the two winding tubes and extending out of the two winding tubes. One end of each wire is electrically connected to the test instrument.

[0008] As a further improvement to this technical solution: the winding structure includes two driven gears, which are respectively fixedly connected to the outer ring sidewalls of the two winding tubes. A T-shaped rotating rod is rotatably connected to the sidewall of the detection box. One end of the T-shaped rotating rod passes through the sidewall of the detection box and extends into the winding cavity. The outer ring sidewall of the T-shaped rotating rod is rotatably connected to the sidewall of the detection box through a bearing. A driving gear is fixedly connected to one end of the T-shaped rotating rod. The driving gear meshes with the two driven gears and is located between the two driven gears.

[0009] As a further improvement to this technical solution: the surface of the T-shaped rotating rod is provided with anti-slip texture.

[0010] As a further improvement to this technical solution: anti-slip pads are provided on both sides of the detection box.

[0011] As a further improvement to this technical solution: the side wall of the detection box is fixedly connected with a strap.

[0012] Compared with the prior art, the beneficial effects of this utility model are: the device can wind and rewind the wires separately through the cooperation of components such as the detection box, wires, detection pen, and winding tube, thereby preventing the wires from being randomly tangled and knotted. It is simple, convenient and quick to operate.

[0029] The working principle of this utility model is as follows: When using this device, take out the detection pen 6 and the detection clip 8, clip the detection clip 8 onto the ground housing of the object being tested, and then use one end of the detection pen 6 to contact the terminal to be tested. Then, check whether the terminal has an insulation fault through the detection instrument 3. After use, rotate the T-shaped rotating rod 12. The T-shaped rotating rod 12 drives the drive gear 13 to rotate. When the drive gear 13 rotates, it can simultaneously drive the two driven gears 14 to rotate. The two driven gears 14 drive the two winding tubes 10 to rotate, thereby simultaneously winding the two wires 4, thus preventing the wires 4 from being randomly tangled and knotted. Then, the detection pen 6 and the detection clip 8 can be placed in the pen slot 7 and the clip slot 9 respectively for storage.
