Description

Technical Field

[0001] The utility model relates to the field of watch component structures, and particularly to an anti-static structure for a watch. Background Art

[0002] During processes such as packaging, transportation, and assembly, a watch becomes an electrostatic charge carrier due to friction and other mechanical actions. Traditional parts such as glass and seals are insulators. Once static charges are generated, they are neither easily distributed on the surface of the whole object nor easily conducted to other objects in contact with it. Therefore, local surface charges accumulate continuously. When the static electricity accumulates to a certain extent, it will damage the internal structure of the watch.

[0003] Static electricity may cause the watch to stop running or the watch hands to deviate. Especially in dry winters, due to the dry air, static electricity is easily accumulated and not easily dissipated. This application proposes an anti-static structure for a watch to avoid the phenomenon of second skipping caused by static electricity accumulation on the watch. Summary of the Utility Model

[0004] The purpose of the utility model is to address the above problems and propose an anti-static structure for a watch.

[0005] The utility model proposes the following technical solutions:

[0006] The utility model proposes an anti-static structure for a watch, which includes a metal watch case and a watch glass. A metal ring-shaped boss protrudes from the inner wall of the metal watch case; a conductive film is plated on the inner surface of the watch glass, and the watch glass is fixedly supported on the metal ring-shaped boss, and the conductive film on the inner surface of the watch glass is in contact with the metal ring-shaped boss.

[0007] In the above anti-static structure for a watch of the utility model, the anti-static structure for a watch further includes a metal bottom cover installed at the bottom of the metal watch case.

[0008] In the above anti-static structure for a watch of the utility model, the metal watch case includes a metal shell body, and a stepped hole is formed at the top of the metal shell body; the metal watch case further includes a metal front ring fixedly installed in the stepped hole;

[0009] The metal ring-shaped boss is formed on the metal front ring.

[0010] In the anti-static structure for a watch of the utility model, the watch glass with a conductive film plated on its inner surface and the metal watch case form a conductive closed body. When we wear the watch, the metal watch case contacts the human body, thereby introducing the static electricity accumulated on the watch glass into the ground, and the problem of static electricity conduction can be solved. This structure improves the anti-static performance of the watch and protects the movement and the watch from static electricity damage. Brief Description of the Drawings

[0011] The following further illustrates the utility model with reference to the drawings:

[0012] Figure 1 Shows a schematic structural diagram of the anti-static structure of the watch according to the first embodiment of the present application;

[0013] Figure 2 Shows a schematic structural diagram of the anti-static structure of the watch according to the second embodiment of the present application. Detailed implementation manners

[0014] Generally, the watch structure includes a watch case, a bottom cover, a watch glass, a movement and a seal. Among them, the watch case and the bottom cover usually adopt SUS316L stainless steel materials and are both conductors; while the watch glass is made of sapphire, crystal glass, etc. and is an insulator; the material of the seal is mostly TELFEL and is an insulator. During actual assembly, the seal will generate static electricity when rubbing against the watch glass and the watch case. Since both the seal and the watch glass are insulators, the charges cannot flow and cannot be leaked, but are adsorbed on the inner surface of the glass, which will cause the phenomenon of jumping seconds.

[0015] The anti-static structure of the watch of the present application forms a conductive closed body with a watch glass with a conductive film plated on its inner surface, a metal watch case and a metal bottom cover. When we wear the watch, the metal watch case contacts the human body, thereby introducing the static electricity accumulated on the watch glass into the ground, and the problem of static electricity conduction can be solved. This structure improves the anti-static performance of the watch and protects the movement and the watch from static damage.
