Abstract

The utility model relates to a watch crown antistatic structure. A fine static conducting path which is formed between a metal crown of the watch crown antistatic structure and a metal bottom cover can effectively prevent generating electrostatic fields, thereby achieving electrostatic resistance. The watch crown antistatic structure comprises a clock mechanism component and the bottom cover, wherein the clock mechanism is fixedly arranged in a watchcase, a penetrating hole is arranged at one lateral end of the watchcase, the crown is sleeved in the penetrating hole, the bottom cover is used for packaging the clock mechanism in the watchcase, a spring which keeps proper interference with a rod of the crown is sleeved on the rod of the crown, and a mandrel of the clock mechanism component is nested in a blind hole concavely and axially arranged on the front end portion of the rod of the crown. The spring sleeved on the rod of the crown contacts with a switch elastic plate of the clock mechanism component after being compressed. When electrostatic is generated around the crown, current is conducted from the crown to the switch elastic plate and a positive electrode of a power supply of the clock mechanism via the spring, and then the electrostatic can be discharged through the fine conducting path between the metal crown and the metal bottom cover.

Description

Wrist-watch handle electrostatic prevention structure

Technical field

The utility model relates to a kind of wrist-watch handle electrostatic prevention structure.

Background technology

In traditional " numeral+row Needles shows accutron ", handle and bottom Shi Difficult are reliably to link to each other or not connect, so antistatic property is poor.

The utility model content

The purpose of this utility model is to overcome above-mentioned weak point of the prior art, suit one metal spring on a kind of metal handle of wrist-watch is provided, handle fully contacts with metal spring, metal spring fully contacts with the metal clips of internal machine core, metal clips touches the metal bottom cover of wrist-watch again, and handle realizes reliably that by spring and bottom electrical property links to each other.Like this, form a good static pathway between metal handle and the metal bottom cover, the release electrostatic lotus prevents the generation of electrostatic field effectively, thereby reaches the wrist-watch handle electrostatic prevention structure of antistatic effect.

The purpose of this utility model can reach by following measure:

This wrist-watch handle electrostatic prevention structure, comprise the cartridge assemblies that is installed in the watchcase, the watchcase side is provided with perforation, suit handle in this perforation, the bottom of packaging machine core assembly in watchcase, its special character is: be set with the spring with the suitable magnitude of interference of its maintenance on the bar of the described handle footpath, handlebar stem footpath front end end axis is nested with the mandrel of cartridge assemblies to the blind hole that is arranged with; Switch shrapnel with cartridge assemblies after the described length of spring compressed that is sleeved on the handlebar stem footpath touches; When producing static around the handle, electric current links to each other with metal bottom cover through the movement switch shrapnel from the hand channel spring is imported the movement switch shrapnel again, thereby forms good pathway release electrostatic between metal handle and metal bottom cover.

The utlity model has following advantage:

1, owing to have elastic force after the spring assembling compression and elastic force is less, thus can guarantee that the conducting of handle and cartridge assemblies switch shrapnel is good, and to the allomeric function after assembling without any harmful effect.

2, Spring Card has guaranteed that at the handle front end spring can not drop out when the dismounting handle.

3, have the assembling of production easily, the electrical property contact is good between part.

Embodiment

The utility model is described in further detail below in conjunction with accompanying drawing:

See also shown in the accompanying drawing, in the present embodiment, described movement wrist-watch handle electrostatic prevention structure, comprise the cartridge assemblies 2 that is installed in the watchcase 1, watchcase 1 side is provided with perforation 11, suit handle 3 in this perforation 11, the bottom 4 of packaging machine core assembly 2 in watchcase 1, be set with the spring 5 with the suitable magnitude of interference of its maintenance on the bar of described handle 3 footpath 31, handlebar stem footpath 31 front end end axis are nested with the mandrel 21 of cartridge assemblies to the blind hole 32 that is arranged with; Switch shrapnel 22 with cartridge assemblies after described spring 5 compressions that are sleeved on the handlebar stem footpath 31 touches; When having static charge around the handle 3, electric current imports movement switch shrapnel 22 from handle 3 through spring 5, links to each other with metal bottom cover 4 through movement switch shrapnel 22, thereby form good pathway release electrostatic between metal handle 3 and metal bottom cover 4.

The above only is preferred embodiment of the present utility model, and all equalizations of being done according to the utility model claim scope change and modify, and all should belong to the covering scope of the utility model claim.

Claims

1, a kind of wrist-watch handle electrostatic prevention structure, comprise the cartridge assemblies that is installed in the watchcase, the watchcase side is provided with perforation, suit handle in this perforation, the bottom of packaging machine core assembly in watchcase, it is characterized in that: be set with the spring with the suitable magnitude of interference of its maintenance on the bar of the described handle footpath, handlebar stem footpath front end end axis is nested with the mandrel of cartridge assemblies to the blind hole that is arranged with; Switch shrapnel with cartridge assemblies after the described length of spring compressed that is sleeved on the handlebar stem footpath touches; When producing static around the handle, electric current links to each other with metal bottom cover through the movement switch shrapnel from the hand channel spring is imported the movement switch shrapnel again, thereby forms good pathway release electrostatic between metal handle and metal bottom cover.
