[0002] In the process of power detection, instruments are often used to measure the leakage current value and the shell leakage voltage value of circuits and their electrical equipment. In the prior art, most of these instruments are intelligent multimeters.

[0003] For example, the intelligent remote control digital multimeter provided by the patent application number CN202022916463.6 includes a multimeter dial. One end of the multimeter dial is fixedly connected with a tray. A measuring device is clamped in the inner cavity of the tray. A battery slot is arranged in the inner cavity of the measuring device. A lithium battery is electrically connected in the inner cavity of the battery slot. There are two lithium batteries. A clamping cover is slidably connected to the outer end of the battery slot. And one side of the measuring device is fixedly connected with a USB interface, and the USB interface is plugged into one end of the multimeter dial.

[0004] Based on the above search and combined with the prior art, it is found that most of the on-line measuring instruments similar to those disclosed above in the prior art are composed of an instrument main body, a measuring pen and a wire harness. After the on-line measuring instrument is used, the measuring pen and the wire harness are often not well stored. And during the transfer of the whole instrument, the display screen on the instrument is also prone to scratching and wear. Therefore, a portable on-line measuring instrument for electrician leakage voltage is proposed to improve the above problems. Content of the Utility Model

[0005] The purpose of this application is to provide a portable on-line measuring instrument for electrician leakage voltage to solve the problems put forward in the above background technique.

[0006] To achieve the above purpose, this application provides the following technical solution: A portable on-line measuring instrument for electrician leakage voltage includes a shell, a measuring instrument and a measuring pen. The measuring instrument is fixedly installed on the inner wall of the shell. And a storage bin is fixedly connected to the remaining space inside the shell. Two groups of connecting frames are fixedly connected to the inner wall of the storage bin. And a buckle assembly for positioning the measuring pen is arranged between the two groups of connecting frames. A shaft rod is fixedly connected to the top of the shell. And a rotating sleeve is rotatably connected to the outer surface of the shaft rod. And a cover plate is fixedly connected to the outer surface of the rotating sleeve. And the cover plate overlaps on the front end face of the shell.

[0007] As a further supplement to this solution, metal sheets and magnetic attraction sheets are respectively embedded on the opposite surfaces of the cover plate and the shell. And the magnetic attraction sheet is magnetically connected to the metal sheet.

[0008] As a further supplement to this solution, a convex piece is fixedly connected to the bottom of the cover plate. A rubber cushion layer is fixedly connected to the front end face of the shell. And the front end face of the rubber cushion layer abuts against the cover plate.

[0009] As a further supplement to this solution, a damping cushion layer is fixedly connected to the inner wall of the rotating sleeve, and the inner wall of the damping cushion layer abuts against the outer wall of the shaft rod.

[0010] As a further supplement to this solution, the buckle assembly includes two U-shaped frames. The two U-shaped frames are respectively connected to the two connecting frames, and snap rings are fixedly connected to the tops of the two U-shaped frames. The snap rings are snap-connected to the outer wall of the measuring pen.

[0011] As a further supplement to this solution, the snap ring and the U-shaped frame are integrally formed.

[0012] In summary, the technical effects and advantages of the present utility model are as follows:

[0013] 1. In the present utility model, the convex piece drives the cover plate to flip. The rotating sleeve on the top of the cover plate rotates along the shaft rod, and the damping cushion layer inside the rotating sleeve can provide damping performance between the rotating sleeve and the shaft rod, so that the cover plate can maintain a relatively stable angle with the housing, and thus the whole instrument can be stably placed upright on the working platform. At this time, the measurement of the leakage voltage can be realized through the cooperation of the measuring pen, the measuring instrument and the wire harness. After the voltage measurement is completed, the wire harness can be folded and placed inside the storage bin, the measuring pen can be clamped between the two snap rings, and finally the cover plate is reset. At this time, the cover plate can protect the measuring pen and the measuring instrument. Therefore, while ensuring the convenience of using the on-line measuring instrument for electrician leakage voltage, the storage of the wire harness and the measuring pen is realized, and the protection of the measuring instrument can also be completed.

[0014] 2. In the present utility model, after the cover plate is reset, the damping cushion layer can ensure the fitting state between the cover plate and the front end face of the housing. At this time, the metal sheet on the cover plate is attracted to the magnetic attraction sheet on the housing, and through the magnetic attraction force generated by the two, the stability and airtightness of the connection between the housing and the cover plate are further ensured, thereby improving the use effect of the on-line measuring instrument for electrician leakage voltage.

[0023] The cover plate 2 is driven to flip by the protrusion 6, the rotating sleeve 3 on the top of the cover plate 2 rotates along the shaft rod 10, and the damping cushion layer 4 inside the rotating sleeve 3 can provide damping performance between the rotating sleeve 3 and the shaft rod 10, so that the cover plate 2 can maintain a relatively stable included angle with the housing 1, so that the whole instrument can be stably placed on the working platform. At this time, the measurement of the leakage voltage can be realized through the cooperation of the measuring pen 15, the measuring instrument 7 and the wire harness. After the voltage measurement is completed, the wire harness can be folded and placed inside the storage bin 8, the measuring pen 15 is clamped between the two snap rings 12, and finally the cover plate 2 is reset.

[0024] On the opposite faces of the cover plate 2 and the housing 1, metal sheets 5 and magnetic attraction sheets 9 are respectively embedded, and the magnetic attraction sheet 9 is magnetically connected to the metal sheet 5. After the cover plate 2 is reset, the damping cushion layer 4 can ensure the fitting state of the front end faces of the cover plate 2 and the housing 1.

Through the magnetic attraction force generated by the two, the stability and airtightness of the connection between the housing 1 and the cover plate 2 are further ensured.

[0025] A convex piece 6 is fixedly connected to the bottom of the cover plate 2 to facilitate the flipping of the cover plate 2. A rubber cushion layer 14 is fixedly connected to the front end face of the housing 1, and the front end face of the rubber cushion layer 14 abuts against the cover plate 2 to ensure the tight connection between the cover plate 2 and the housing 1.

After the cover plate 2 is reset, the damping cushion layer 4 can ensure the fitting state of the front end faces of the cover plate 2 and the housing 1. At this time, the metal sheet 5 on the cover plate 2 is attracted to the magnetic attraction sheet 9 on the housing 1. Through the magnetic attraction force generated by the two, the stability and airtightness of the connection between the housing 1 and the cover plate 2 are further ensured, thereby improving the use effect of the on-line measuring instrument for electrician leakage voltage.
