Abstract
The invention discloses a kind of removable eyesight correction device and fixing means for being built in full facepiece mask, for solve the problems, such as eyesight when rectifier the dimness of vision when bore hole uses respiratory protection class full facepiece mask.The eyesight correction device is included without temple spectacle-frame, spectacle-frame support member.The spectacle-frame is connected with the spectacle-frame support member and is integral；The spectacle-frame support member bottom is torsionspring clip, and the spring clip is directly sandwiched in inside full facepiece mask at the centre of oronasal mask；The vertical clamping adjustable length of the torsionspring clip, and clamping plate is cased with antiskid glue sleeve respectively before and after the torsionspring clip, prevents spectacle-frame from being loosened in mask interior edge left and right, up and down direction.The fixing means that the support member is held on inside full facepiece mask at oronasal mask is applied to all kinds of common full facepiece masks of in the market, without additionally treating that rectifier configures dedicated facemask for eyesight, saves mask investment.The eyesight correction device is integrally built in full facepiece mask, does not influence the air-tightness of full facepiece mask.
Description
Technical field
The present invention relates to oil, chemical industry, mine, metallurgy, military affairs, fire-fighting, rescue and relief work, health and epidemic prevention and science and technology environmental protection etc.
The personal extraordinary articles for labour protection technical field in field, it is complete that one kind of more particularly to petrochemical field is built in respiratory system protection
The eyesight correction device and fixing means of mask.
Background technology
According to statistics, more than 95% cooupational intoxication is caused by be harmful substance enter body through respiratory apparatus, thus full facepiece mask
It is to ensure special operation workers health, effective appliances for labor protection of safety.For the common full facepiece mask produced on the market at present, by
Everybody group is the normal person of UCVA.If eyesight treats that rectifier retains institute's wearing spectacles and dresses such full facepiece mask, will cause
Full facepiece mask is poorly sealed, and then causes full facepiece mask to reach respiratory system protection function.And eyesight treats that rectifier's bore hole is dressed
Greatly inconvenience and potential safety hazard in Special Work occasion operation be present in full facepiece mask.
In view of the above-mentioned problems, if eyesight treats that rectifier's contact lens carry out the wearing of full facepiece mask, because of wear contact
Glasses are time-consuming longer and are not excluded for contact lens and allergic symptom crowd occur, and in case of emergency the method is worthless.
CN 205127192 U（Meng Fanjun）Deng the vision correction structure being applied in gas mask invented, need additionally in mask
The boss of connection vision correction structure is set above side, and spacing spiral shell up and down need to be screwed during the structural adjustment glasses height simultaneously
Nail, more time-consuming, practicality is not high under emergency condition；CN 204864595 U（Zhao Yong）Deng a kind of air respiratorresuscitator face of invention
Cover vision correction tool clamp holder, truss structure part therein is more, and making is complex, and the side of being provided with mask face
Hole, face intensity is not only influenceed, and it is larger to change cost；CN 202459892 U（Yang Faping）Deng the air respiratorresuscitator of invention
Spectacle frame, the spectacle frame are stuck in face lower edges by upper lower bayonet slot and are fixed, and the fixed form causes the spectacle frame only
It is only applicable to be positioned over the mask of a certain particular geometric profile and size.The spectacle frame does not possess universality, marketing by
Limitation.
The content of the invention
The purpose of the present invention is the vision correction technological deficiency for being currently used in full facepiece mask, there is provided a kind of universality
By force, install or win eyesight correction device and fixing means convenient, that do not change original comprehensive cover structure or part.
The object of the present invention is achieved like this：
A kind of eyesight correction device for being built in full facepiece mask, the device are included without temple spectacle-frame, spectacle-frame support member two parts,
The spectacle-frame is connected with the support member and is integral.
In above-mentioned eyesight correction device, the spectacle-frame support member possesses the fastening eyesight correction device in full facepiece mask
Function, prevent the spectacle-frame from rocking the function of the vertical position of function, the regulation eyesight correction device in full facepiece mask.
In above-mentioned eyesight correction device, the spectacle-frame support member lateral plan profile is L-shaped；The spectacle-frame support
Part includes a torsionspring clip；The torsionspring clip is directly sandwiched in the center of oronasal mask inside respiratory protection class full facepiece mask
At centre, so as to which the eyesight correction device is integrally attached in mask；The vertical clamping adjustable length of the torsionspring clip,
To adapt to different wearer's eyes present positions；The torsionspring clip chucking power is larger, and before the torsionspring clip
Latter two clamping plate is respectively provided with antiskid glue sleeve, to increase frictional force of the clamping plate with oronasal mask, prevents no temple spectacle-frame in face
Cover interior edge left and right, up and down direction loosens.
In above-mentioned eyesight correction device, the eyesight correction device can be carried out by torsionspring clip described in manual operation
Freely install or win.
Above-mentioned eyesight correction device is integrally built in full facepiece mask, does not influence the air-tightness of full facepiece mask.
The present invention also provides a kind of fixing means for the eyesight correction device for being built in full facepiece mask, the eyesight correction device
It is fixed at the oronasal mask centre inside full facepiece mask；The eyesight correction device is also by the torsionspring clip clamping plate
Antiskid glue sleeve strengthen steadiness of the eyesight correction device in full facepiece mask.
In above-mentioned eyesight correction device fixing means, the eyesight correction device is clamped by the torsionspring clip
At oronasal mask centre inside full facepiece mask carry out upper and lower to fixation；
In above-mentioned eyesight correction device fixing means, the eyesight correction device prevents the mirror by the antiskid glue sleeve
Outline and now rock.
The clear superiority of the present invention is：
Eyesight correction device is directly sandwiched in oronasal mask inside respiratory protection class full facepiece mask by torsionspring clip（Silica gel or rubber
Material）Centre at, and torsionspring clip clamping length is adjustable, to adapt to different wearer's eyes present positions, so as to
