Description

Technical Field

[0001] The invention relates to the technical field of magnetic field measurement, and in particular to a desktop magnetic field measuring instrument. Background Art

[0002] Magnets are widely used in electronic devices, such as speakers. When installing magnets into electronic devices, it is necessary to ensure that the magnets are installed in the correct direction and that the magnets can provide sufficient magnetic field strength to enable the electronic devices to work properly. Now, a gaussmeter is usually used to measure the strength of the magnetic field. The gaussmeter includes a main body and a measuring pen connected to the main body, and a display screen is provided on the main body. By contacting the measuring pen with the measured component, the display screen will obtain the measured value. However, the gaussmeter cannot measure the south pole and north pole of the magnet. Therefore, the wrong installation direction of the magnet will still occur during the installation process.

[0003] For example, the patent application with application number CN201010598604.2 includes a base and a measuring mechanism arranged on the base, the measuring mechanism includes a mounting plate connected to the base, a swing arm rotatably connected to the mounting plate, a connecting block fixedly connected to the top of the mounting plate, and an elastic member located between the connecting block and the swing arm, a measuring magnet opposite to the base is connected to the swing arm, and the magnetic field measuring instrument also includes a displacement sensor arranged on the base and opposite to the swing arm. The above magnetic field measuring instrument has the advantages of being able to measure polarity and intensity at the same time and being simple to operate.

[0004] When the magnetic field measuring instrument mentioned above and in the prior art measures a magnet, if a magnet with a large magnetic force and a small mass is measured, the magnet to be measured will be magnetically attracted to the measuring magnet, resulting in the inability of the magnetic field measuring instrument to measure it. If a magnet with a large magnetic force and a large mass is measured, when the displacement sensor reaches its limit, the measuring magnet will be magnetically attracted to the magnet to be measured, thereby driving the swing arm to bend, thereby damaging the magnetic field measuring instrument. In addition, the size of each magnet to be measured is different, and the magnetic field measuring instrument cannot adjust the position of the measuring magnet according to actual needs, thereby reducing the use effect of the magnetic field measuring instrument. Therefore, it is urgent to design a desktop magnetic field measuring instrument to solve the above problems. Summary of the invention
