Embodiment 1

[0031] Please refer to the attached Figure 1 , the anti-magnetic quartz wrist watch includes: a case 70, a dial 10, a movement 30 and a bottom cover 60, the position between the movement 30 and the dial 10 is made of a material with high magnetic permeability and is made of In the first shielding cavity that shields the magnetic field from the top of the dial 10; between the movement 30 and the bottom cover 60, there is a first shielding cavity that is made of a material with high magnetic permeability and is used to shield the magnetic field from the bottom of the bottom cover 60. Two shielding cavity. It should be noted that the first shielding cavity and the second shielding cavity can effectively shield the external magnetic field from two directions above and below the watch, which will substantially affect the quartz movement watch.

[0032] The first shielding chamber comprises a first shielding sheet 22, a first shielding ring 21 and a second shielding sheet 20 arran...

Embodiment 2

[0038] Please refer to the attached Figure II, the second embodiment provided by the present invention includes: a watch case 70, a dial 10, a movement 30 and a bottom cover 60; And it is used to shield the first shielding cavity from the magnetic field above the dial 10; between the movement 30 and the bottom cover 60, a material with high magnetic permeability is used to shield the magnetic field from the bottom of the bottom cover 60 The second shielded cavity. It should be noted that the first shielding cavity and the second shielding cavity can effectively shield the external magnetic field from two directions above and below the watch, which will substantially affect the quartz movement watch.

[0039] In addition, a first shielding groove plate 23 is disposed between the movement 30 and the dial 10 .

[0040] In detail, a groove is opened in the middle of the upper end surface of the first shielding groove plate 23, and the dial 10 is closely attached to the upper en...

Abstract

The invention belongs to the watch technical field and relates to an anti-magnetic quartz needle watch. The anti-magnetic quartz needle watch comprises a movement, a dial, a case and a bottom cover; a first shielding cavity which is made of a high-magnetic permeability material and is used for shielding a magnetic field from space above the dial is arranged at a position between the movement and the dial; and a second shielding cavity which is made of a high-magnetic permeability material and is used for shielding a magnetic field from space below the bottom cover is arranged at a position between the movement and the bottom cover. According to the anti-magnetic quartz needle watch of the invention, the external magnetic fields, namely, the magnetic fields from the directions of the dial and the bottom cover, which may exert substantive influence on the quartz needle watch can be guided to the first shielding cavity and the second shielding cavity, so that the magnetic lines of force of the magnetic fields are under the action of the first shielding cavity and the second shielding cavity, so that the magnetic fields can be shielded, and therefore, the time keeping of the watch will not be affected by the magnetic fields, and the accuracy of the time keeping of the watch can be ensured.

Description

technical field [0001] The invention belongs to the technical field of quartz watches, in particular to an antimagnetic quartz watch with needles. Background technique [0002] Watches, especially quartz needle watches, are mainly affected by the magnetic field from above and below the watch. The movement inside the quartz needle watch is composed of permanent magnet stepping motor, integrated circuit, battery, quartz resonator, etc. When its As for the external magnetic field, the above-mentioned parts of the movement will affect the work due to the magnetic field. [0003] The antimagnetic technology generally adopted by existing quartz needle watches is to add an alloy interlayer on the back cover of the watch. However, due to the limitations of the structure of the prior art quartz needle watch, there are still the following technical problems: when the watch is placed in an external magnetic field, the movement parts are likely to affect the work due to the magnetic fi...
