Embodiment Construction

[0029] The watch of the present invention comprises a casing, a shield, a dial, a movement arranged in the shield, an elastic element arranged between the casing and the shield, and the dial and the shield are made of a material with high magnetic permeability As a result, the dial is close to the upper end of the shield to form a closed shield. The following describes in detail in conjunction with the embodiments.

[0030] Such as image 3 As shown, in the first embodiment of the watch of the present invention, it includes a casing, a shield, a dial 10, a movement 40, and an elastic element arranged between the casing and the shield. The shielding cover comprises a lower cover 23 and a side ring 22 fixed on the lower cover 23 by screws, and the side ring 22 is provided with a bar or a pressing avoidance hole 30, the movement 40 is placed in the shielding cover, and the dial 10 is covered on the side. On the ring 22, the movement 40 is sealed in the shielding case, and the d...

Abstract

The invention relates to a wrist watch, comprising a shell, a shielding cover, a letter tray, a clock mechanism arranged in the shielding cover and an elastic element arranged between the shell and the shielding cover. The letter tray and the shielding cover are made from materials with high magnetic conductivities. The letter tray clings to the upper end of the shielding cover tightly so as to form a closed shielding. The wrist watch in the invention realizes the functions of magnetism resisting and vibration enduring, thereby satisfying the requirements of high magnetism resisting and vibration enduring.

Description

technical field [0001] The invention relates to the field of timing tools, more specifically, to an antimagnetic and vibration-resistant watch. Background technique [0002] Watches, especially the movement parts in mechanical watches are made of metal. When placed in an external magnetic field, the movement parts will be magnetized to varying degrees, which will affect the speed of the watch and even stop the watch; After exiting the magnetic field, due to the residual magnetism of some parts, it will also affect the travel time of the watch. In order to eliminate this effect, antimagnetic design is required. The general measure is to add a magnetic shield outside the movement. figure 1 It shows a structural diagram of a prior art antimagnetic watch, including a dial 10, a magnetic shielding ring 20, and a movement 40. The magnetic shielding ring 20 is made of a material with high magnetic permeability and is sleeved outside the movement 40. , Between the movement 40 and...
