Description
Technical field
The present invention relates to electrostatic arts, and in particular to cantilevered human body electrostatic discharge device.
Background technique
Electrostatic is a kind of objective natural phenomena, and the mode of generation is a variety of, such as contact, friction, removing.Human body accumulation is quiet
Electricity harm health: the symptoms such as somebody's skin allergy, heart rhythm disorders, headache and insomnia and dysphoria, also somebody's tough hair
It is vertical, it is nervous.Fear to contact metal object.In addition, touch computer can make computer crash when human body puts aside electrostatic, electronics is produced
The harm such as product component punctures, and combustibles are lighted.The electrostatic on human body can be rapidly eliminated using human body electrostatic eliminator.People
It is so that circuit is worked using the electrostatic on human body using a kind of passive type circuit to body Xelminator, and it is quiet to finally reach elimination
The effect of electricity.It has the characteristics that it is small in size, light-weight, be not required to power supply, eliminate electrostatic when insentience.Human body electrostatic discharge device packet
It includes sequentially connected mounting assembly, L shape metal arm and touches ball head device.The appearance for touching ball head device is by stainless steel ball system

Human body electrostatic eliminator is divided into vertical type human body Xelminator according to installation site and cantilevered static electricity on human body eliminates
Device.Vertical type human body Xelminator is mounted directly the grounding pin on the ground, being grounded and is inserted directly into underground 30cm depth,
Or it is connect with ground pile.Vertical type human body Xelminator will not hinder other operations since it occupies little space on the ground
Equipment and pedestrian are commonly used on Workplace or large oil tank.The installation group of existing cantilevered human body electrostatic eliminator
Part is mounting disc and bolt, mounting disc is fixed on wall or the shell of equipment by bolt, as shown in Figure 1.This peace
Assembling structure not only needs more people to install during installation: worker's righting mounting disc, another worker is with tool by bolt
It is tightened in after mounting disc on wall or the shell of equipment.Meanwhile during installation, it needs to tighten on each bolt, operate
Duration, later period demolition and maintenance trouble.And for outdoor cantilevered human body electrostatic eliminator, consolidated using screw thread
Fixed, the antirust paint on screw thread causes thread to get rusty easily by acid rain corrosion, and the later period, which can not be successfully, to be disassembled.
Summary of the invention
It is an object of that present invention to provide cantilevered human body electrostatic discharge devices, solve existing cantilevered human body electrostatic eliminator
The problem of mounting assembly installation is inconvenient, low efficiency and thread easily get rusty.Therefore the present invention designs cantilevered static electricity on human body and releases
Device is put, bolted structure is changed to the connection structure that the present invention designs, can not only be installed by a worker, and
Installation steps are simple, installation speed is fast, and are convenient for the demolition and maintenance in later period, it is thus also avoided that the case where generating thread corrosion.
The present invention is achieved through the following technical solutions:
