Description
Technical field
The utility model relates to office seating technical field more particularly to a kind of Anti-static chairs.
Background technique
Electrostatic is ubiquitous in our work and lifes, is a kind of common electrification phenomenon, when two kinds it is of different nature
When the mutual friction of object phase or contact, electronics transfer will be occurred between object, a kind of substance electronics be transmitted to another substance and band just
Electricity, another substance obtain electronics and negatively charged, and when insulating with the earth, charge can not leak and rest on the interior of object
Portion or surface are in relative static conditions, and this immobilising charge is known as electrostatic.
Electrostatic effect is divided into four kinds, the first is electrostatic mechanics effect, there is electrostatic field around electrostatic charging body, due to
At typical condition, electrostatic field is heterogeneous, will receive the effect of electric field force, stress in the media particles that electrostatic field is polarized
Direction be directed toward electrical body, that is, no matter which kind of polar charge electrical body has, and electrical body is for original uncharged dust
The all attractive effect of grain.Second of fuel factor for static discharge, electrostatic spark electric discharge or brush discharge are typically all
It is completed in nanosecond or musec order.Therefore, static discharge process can usually be regarded as to a kind of adiabatic process.It is sent out in air
Raw static discharge can make air ionization, breakdown by several amperes of high current in moment, and along with shining, generated heat
Journey forms local high temperature heat source.The third is the forceful electric power field-effect of electrostatic.Accumulation of the electrostatic charge on object often makes object
There is high voltage over the ground, nearby form strong electrical field.The 4th kind of electromagnetic pulse effect for static discharge.Static discharge process is
The electromagnetic radiation process of the random transient change of current potential, electric current.
Production equipment failure caused by static discharge is the electricity of the physical phenomenons and electromagnetic wave such as the acousto-optic generated due to electrostatic
Caused by gas phenomenon.Due to widely applying automation control appliance and analysis laboratory apparatus instrument in modern chemical industry production, this
Various electronic components are largely used in a little equipment again, especially for the especially sensitive MOS type integrated circuit of static discharge and
Field effect transistor etc. discharges when intermittence occurs for electrical body, above-mentioned semiconductor device can be made to damage.And when electrical body surface electricity
Lotus density is 10-5-10-4C/m2When, by flashing electric discharge or surface-discharge, there is ionic current between electrical body and grounding body
Simultaneously radiated electromagnetic wave is flowed, the malfunction of the electronic component in the equipment such as computer, electronic instrument and relay, switch can be caused
Make.Meanwhile in chemical production process, the electrostatic that powder processing generates can also reduce production effect in addition to bringing fire and explosion
Rate influences product quality.
Although electrostatic electricity less, is easy to happen electric discharge because its voltage is very high, electrostatic spark is generated.Therefore, having
There are the Work places of flammable liquid, fire may be caused by electrostatic spark；With explosive dust or explosive gas, steam
Place, may be set off an explosion by electrostatic spark, and then damage equipment and other properties.
With the development and application of high speed, high pressure technique and high molecular material, the harm of electrostatic is more prominent.One
A little special production working environments, such as Electronic Components Manufacturing workshop, because people are in daily life, sometimes due to wearing
, weather, the reasons such as friction, frequently result in body accumulation electrostatic, and touch metal electron suddenly in production process or work
When component, the damage of electronic component can be caused even to burn because of the electrostatic on body.Currently, existing office seating
Do not have the function of antistatic usually, normally the electrostatic normal ground on body can not disappear during production work
It removes, to exclude security risk.

Electric seat.
To achieve the goals above, the utility model adopts the following technical solution: a kind of Anti-static chair, including the chair back,
Seat and chair leg are provided with metallic conductor in leg, and the metallic conductor is connected with active conductive portion by fastener
Part, the fastener include button movable part and button fixed part, and the button fixed part is located at the table of metallic conductor
On face, the active conductive component includes metallic plug and patchcord, and the metallic plug connects patchcord one end, the switching
Line middle section is flexible spiral lead, and the patchcord other end connects button movable part, and the metal is inserted
Head insertion ground hole, the chair back and seat are equipped with antistatic chair cover outside, and the antistatic chair cover is three layers, respectively PVC chair
Internal layer, antistatic chair cover middle layer and PVC chair cover outer layer are covered, conductive fiber, the PVC chair cover are inlaid in PVC chair cover outer layer
Outer layer is connected with chair leg top.
Button movable part is connected with button fixed part, realizes the connection of active conductive component and metallic conductor, gold
Belong to plug and be inserted into ground hole, so that seat has the effect of antistatic.
Patchcord on active conductive component, intermediate portion are divided into flexible spiral lead, convenient for the shifting of seat
It is dynamic.
Antistatic chair cover is set as three layers, respectively PVC chair cover internal layer, antistatic chair cover middle layer and PVC chair cover outer layer,
It is inlaid with conductive fiber in PVC chair cover outer layer, when metallic plug is likely to occur loosening, it is anti-that antistatic chair cover has seat
Electrostatic efficiency.
Wherein, the antistatic chair cover middle layer is lauroyl diethanolamine spray coating.
Wherein, leg bottom end is set as integral die-cast chromium plating aluminium alloy star base, and the integral die-cast chromated aluminum closes
