[0002] Leakage is one of the common faults of lines or equipment. It refers to the current leakage caused by insulation damage or other reasons of the lines or equipment. Different from the short-circuit fault phenomenon, leakage refers to the shunting phenomenon of the line. During the use of household appliances, once leakage occurs, it is very dangerous. When leakage may exist, a multimeter is generally used for detection.

[0033] The following is combined with Figure 1-7 This application is described in further detail.

[0034] The present application discloses a leakage detection device for household appliances. Figure 1-7 A leakage detection device for household appliances, comprising a support plate 1, a multimeter body 2 is placed inside the support plate 1, a positioning mechanism 3 is arranged on the support plate 1, the positioning mechanism 3 comprises a mounting seat 31, the mounting seat 31 is fixedly connected to the bottom of the support plate 1, a mounting block 32 is arranged at the bottom of the mounting seat 31, the mounting block 32 extends into the mounting seat 31, a rotating shaft 33 is rotatably connected inside the mounting seat 31, the rotating shaft 33 extends out of the mounting seat 31, the rotating shaft 33 passes through the mounting block 32 and is fixedly connected to the mounting block 32, a rectangular plate 34 is arranged at the bottom of the support plate 1, a suction cup 35 is fixedly connected to the bottom of the rectangular plate 34, a hollow rod 36 is fixedly connected to the top of the rectangular plate 34, and a sleeve 37 is rotatably connected to the top of the hollow rod 36;

[0035] A threaded mounting rod 38 is provided inside the hollow rod 36, and the outer side of the threaded mounting rod 38 contacts the inner cavity wall of the hollow rod 36, and the threaded mounting rod 38 passes through the sleeve 37 and is connected to the sleeve 37 by threads. A circular plate 39 is fixedly connected to one end of the rotating shaft 33, and a positioning rod 391 is provided on the top of the circular plate 39, and the positioning rod 391 passes through the circular plate 39. A positioning hole 392 is opened on one side wall of the mounting seat 31, and the positioning rod 391 matches the positioning hole 392. The multimeter body 2 can be flexibly loaded and unloaded from the support plate 1, and the user can directly take it for use after removing it. If there is a scene where it needs to be placed for use, the suction cup 35 at the bottom of the rectangular plate 34 can be adsorbed on the wall or the base surface of the home appliance itself, and the position of the support plate 1 can be adjusted by rotating the sleeve 37. Secondly, the support plate 1 can be directly swung to prompt the support plate 1 to swing with the rotating shaft 33 as the axis, so as to adjust the placement angle of the multimeter, which can be suitable for the user's different angle parameter reading requirements, and effectively improves the convenience during use.

[0036] The top end of the threaded mounting rod 38 extends into the interior of the mounting block 32, and the threaded mounting rod 38 is connected to the mounting block 32 by threads. The threaded mounting rod 38 is connected to the mounting block 32 by threads, so it can be flexibly assembled and disassembled. The outside of the positioning rod 391 is fixedly connected to a limiting ring 393, and a spring 394 is fixedly connected to one side of the limiting ring 393. One end of the spring 394 is fixedly connected to one side of the circular plate 39. The positioning rod 391 passes through the spring 394, and the spring 394 provides an elastic force to the limiting ring 393, further prompting the positioning rod 391 to remain inserted into the positioning hole 392. A vertical groove is provided on the hollow rod 36, and the threaded mounting rod 38 is fixedly connected to a limiting block 395 outside. The limiting block 395 passes through the vertical groove and matches the vertical groove. The limiting block 395 can provide a limit for the threaded mounting rod 38 to prevent it from rotating synchronously with the sleeve 37.

[0037] The positioning mechanism 3 includes a mounting assembly, which includes two rectangular frames 396, both of which are fixedly connected to the top of the multimeter body 2, the top of the rectangular frame 396 fits with the top of the inner side of the support plate 1, and a plug plate 397 is slidably connected inside the rectangular frame 396. A plug hole 398 is opened on the top of the support plate 1, and the plug plate 397 extends out of the rectangular frame 396. The plug plate 397 extends into the plug hole 398 and matches the plug hole 398. Two L-shaped plates 399 are fixedly connected to the top of the support plate 1, and a protective plate 381 is placed on the top of the support plate 1. The protective plate 381 can protect the control surface of the multimeter body 2;

[0038] A spring 382 is fixedly connected inside the rectangular frame 396, and the top of the spring 382 is fixedly connected to the bottom of the plug plate 397. The spring 382 exerts an elastic force on the plug plate 397, prompting the plug plate 397 to remain inserted into the socket 398. A strip plate 383 is slidably connected to the inside of the L-shaped plate 399, and a positioning block 384 is fixedly connected to the bottom of the strip plate 383. The bottom of the strip plate 383 fits the top of the protective plate 381, and the positioning block 384 penetrates the protective plate 381. A threaded control rod 385 is rotatably connected to the top of the strip plate 383, and the threaded control rod 385 penetrates the top of the L-shaped plate 399 and is threadedly connected to the L-shaped plate 399. After the threaded control rod 385 rotates, it can drive the strip plate 383 to move up and down.

[0039] In actual operation, when this device is used, the multimeter body 2 is an existing multimeter device, so its structure is not described here. After pushing the plug plate 397 into the rectangular frame 396, the multimeter body 2 can be placed inside the support plate 1. After placement, the plug plate 397 is pushed by the elastic force of the spring 382. At this time, the plug plate 397 moves to the insertion hole 398, and the multimeter body 2 is installed. The user can directly take it for use. When it is not in use, the protective plate 381 can be placed on the top of the support plate 1, and then the threaded control rod 385 is rotated. The threaded control rod 385 drives the strip plate 383 to move. After the strip plate 383 moves to fit the protective plate 381, the positioning block 384 simultaneously penetrates the protective plate 381. At this time, the installation of the protective plate 381 is completed. The protective plate 381 can effectively protect the control surface of the multimeter body 2 to avoid accidental touch and the like, and the safety is relatively high.

[0040] When the user needs to perform leakage detection operation with both hands, the suction cup 35 at the bottom of the rectangular plate 34 can be adsorbed on the wall or the base surface of the home appliance itself, and the sleeve 37 can be rotated. The sleeve 37 drives the threaded mounting rod 38 to move up and down, so as to adjust the position of the support plate 1. Secondly, after pulling the positioning rod 391 to one side of the positioning hole 392, the support plate 1 can be directly swung to cause the support plate 1 to swing around the rotating shaft 33 as the axis, so as to adjust the placement angle of the multimeter. When adjusted to a suitable angle placement range, a positioning hole 392 in the inner part of this range can be selected to be in a corresponding position with the positioning rod 391. Under the elastic force of the spring 394, the positioning rod 391 is inserted into the positioning hole 392 to cause the multimeter body 2 to maintain the adjusted angle. The above steps can be applied to the user's different angle parameter reading requirements, which effectively improves the convenience during use.

[0041] Finally, the sleeve 37 can be continuously rotated to remove the threaded mounting rod 38 from the hollow rod 36. After removal, the threaded mounting rod 38 can be rotated to separate the threaded mounting rod 38 from the mounting block 32, thereby realizing the function of flexible disassembly and assembly. When the device is not in use, it can be disassembled and stored, and it is also convenient to carry and transport.

[0042] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
