Problems solved by technology
For example, Chinese patent 200820057071.5 discloses a degausser, which describes this type of traditional technology. This traditional technology is inseparable from the power supply. In many places without power connection, this technical device cannot be used.
For example, in the process of maintenance of water supply, gas supply and oil supply, it is necessary to demagnetize some precision mechanical parts. Since there is no power supply, the existing degausser device is powerless

Embodiment Construction
[0018] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.
[0019] see figure 1 and figure 2 , a portable passive degaussing device, including a base 18, a degaussing plate 19, a working panel 1, a degaussing box 8, guide rods 4, 17, extension springs 3, and a trigger mechanism; there are long grooves in the base 18, grooves The built-in degaussing plate 19 is covered with a working panel 1 above the groove, and two parallel linear guide rods 4 and 17 are fixed on the working panel 1 through a fixed block 9. The decreasing direction from big to small is the same. The guide rods 4 and 17 are covered with sliding sleeves 6, and the sliding sleeves 6 are fixedly installed on both sides of the degaussing box 8. The demagnetizing box 8 located between two parallel guide rods can move forward and backward along the guide rods Move, the degaussing box 8 rear end portion is equipped with extension spring hol...

The invention relates to a portable passive demagnetization device which is suitable for demagnetization of small metal parts, instruments and meters. The portable passive demagnetization device comprises a base (18), a demagnetization board (19), a work panel (1), a demagnetization box (8), a guide rod (4), a guide rod (17), a tension spring (3) and a trigger mechanism. The demagnetization board is arranged in the base, the base is covered with the work panel, the two parallel linear guide rods are fixedly installed on the work panel, the direction of the guide rods is the same as the progressive decrease direction from large to small of magnetic intensity generated by the arrangement of magnetic poles in the demagnetization board, the guide rods are sleeved with sliding sleeves (6) which are fixedly installed on the two sides of the demagnetization box, a tension spring fixing frame (5) is arranged at the rear end of the demagnetization box, and a hook (15) is arranged at the front end of the demagnetization box. A tension spring fixing frame (2) is perpendicularly arranged at the rear end of the base. The two ends of the tension spring are connected with the tension spring fixing frame on the demagnetization box and the tension spring fixing frame on the base respectively, and the trigger mechanism is arranged at the front end of the base and matched with the hook of the demagnetization box so that the demagnetization box can be pulled and released.
Description
technical field [0001] The present invention relates to the field of electromagnetic technology. Specifically, the present invention relates to a degaussing device. More specifically, the present invention relates to a portable passive degaussing device, which is suitable for small metal parts, fixtures, small molds, workpieces, instruments and meters degaussing. Background technique [0002] Advanced industrial equipment instruments, precision cutting tools and drills, etc., are easily magnetized. Under various occasions such as lightning, violent vibration, and brushing by magnets, these precision parts or processing tools are magnetized. Once magnetized, precision instruments and meters will have adverse consequences. The degaussing methods in the prior art are all solved by active degaussing machines, which are generally equipped with coils, magnetic conductors, control circuits, etc.; It generates an alternating magnetic field, and the energy decrease of the alter...
