Description
Technical field
The invention belongs to the health care apparatus, relate to a kind of stealthy wide spectrum breath purifying device that is worn on the place, nostril, not only can the airborne dust of ultra high efficiency filtering, pernicious gas, various bacterium and virus, also having Cheap highly effective simultaneously, wear and unload convenient, comfortable convenience, available, characteristics such as do not affect the appearance repeatedly, is that current mankind is avoided respiratory tract infection, prevent disease, kept a healthy important health treatment.
Background technology
Along with the high speed development of the modernization of industry and urban transportation and the continuous lifting of public's material desires, the environment that the mankind depend on for existence goes from bad to worse, no matter be indoor or outdoor, air pollution is all very serious, the dust of pernicious gas and suspension increases severely in the air, popular germ, virus are wreaked havoc, and people have been difficult to look for desirable clean breathing environment.The pollution of air makes hundreds of millions of crowds endure the sufferer that respiratory tract infection causes to the fullest extent and torments (as flu, dust allergy, chronic bronchitis, bronchial astehma, pulmonary emphysema and lung cancer etc.), and causes that annual millions of people's is improper early death.Recently, " global environmental change problem " research report of Britain has been announced a thrilling conclusion: environmental pollution particularly indoor pollution reduces human especially children's intelligence greatly! The WHO interrelated data shows, the number that indoor environmental pollution (formaldehyde etc.) is died from the whole world every year reaches 2,800,000, and Chinese interior decoration association reveals that the annual death toll that is caused by room air pollution in the whole nation has reached 11.1 ten thousand people in the environmental monitoring center.According to the data that up-to-date authoritative institution announces, China has at least 65 ten thousand people to cause death because of air pollution every year, also has more than 100 ten thousand people to die from and the closely-related lung cancer of respiratory tract infection and other cancer simultaneously.How to help people to purify inhaled air, reduce to infect, improve health to be the scientific worker to endeavour the focal issue that solves for a long time, up to the present, the various respiratory purified product is popular on market, more has numerous patent applications to declare at home and abroad.Comprehensively, this field can be divided into five big classes: mouth mask class, face shield (comprising the helmet) and breathing mask class, outer purifier class, miniature built-in nasal obstruction class and the miniature outer filter screen class of pasting of connecting of nasal obstruction to the investigation retrieval of existing product and technology.
The mouth mask class is traditional and the most the most frequently used breath purifying means, the occasion of epidemic diseases such as every flu seasons occurred frequently, sandstorm weather or air dirt, a lot of people can adopt this mode to reduce the chance of catching an illness, but come breath purifying to have 3 wretched insufficiencies with mouth mask:
The inefficiencies that the first purifies.The harmful substance that mouth mask is only can the filtering partial volume bigger (as sand and dust etc.), very little to the filtration result of the less germ of volume, virus, dust and pernicious gas, in addition because it is bigger with facial slit, in the part air nuisance can by the slit slip into.
Its two uncomfortable property that is to use.The long periods of wear mouth mask not only influences attractive in appearance, also brings a lot of inconvenience to the user, at first is influence and people's normal communication; Next is that the moisture of breathing out easily produces mist and influences sight line on glasses; Under hot moist environment, use in addition and can increase sense of oppression.
It three is potential safety hazards.In order to promote the clean-up effect of mouth mask, people have adopted thickening, add in the centre and be soaked with the filter core of sterilization soup or scribble design such as nano silver powder on the surface, this series products has been promoted sterilization filter dirt effect really, but also increased user's vexed pressure, discomfort simultaneously, and this series products exists poisonous soup and nano-powder enter human body, health risk with gas potential safety hazard.
Face shield (comprising the helmet) and breathing mask class are another kind of on the market common breath purifying means, this series products normally adopts the part or all of sealing with face, allow the gas of inspiration reach the breath purifying purpose by the filter core that active carbon (or/and other) is housed, although this class purification efficiency height, but bulky, use inconvenience, the disposable element price often changed is more expensive, the wasting of resources is big, both had a strong impact on attractive in appearance, also influence user's normal communication simultaneously, make that this series products is difficult to popularize.
Connecting the purifier class outside the nasal obstruction is the patented technology that a class does not become product as yet, this class technology utilizes a pair of nasal obstruction that is connected with conduit to replace face shield to play the effect that sealing is breathed, then conduit is linked to each other with the external air cleaning unit that has above-mentioned absorption filter core etc., although having overcome the former substantially, this class technology influences the problem of normal communication, use is inconvenient, influence disposable element price attractive in appearance, frequent replacing is more expensive but exist, problems such as the wasting of resources is big make this class technology do not accepted by market as yet so far.
The patent application of miniature built-in nasal obstruction class is a lot, the attraction of this technology is to use miniature respiratory clarifier, it is filled in nasal cavity, and (or substantially not) influence is not attractive in appearance, although this class have volume little, not too influence advantages such as attractive in appearance, but problem is, the common function singleness of this class filter, filtering face is narrow, efficient is not high, and when filling in the nostril, it is smooth to cause exhaling, simultaneously, because the obstruction of nasal obstruction makes biogas cleaning system (the self-purging functions of nose flagellum and nasal cavital mucus etc.) the forfeiture effect of nasal cavity.Particularly serious is when the miniature clarifier that the poison core will be arranged is filled in the nasal cavity, to exist the potential safety hazard that venom infiltrates human body, health risk.
Miniature outer patent of pasting the filter screen class also is seen in, the advantage of this class technology be easy, stealthy, (or substantially not) influence not attractive in appearance, but shortcoming is that breath purifying weak effect, filtering face are narrow, be only applicable to the filtering of big sand and dust, powerless to other harmful substances (as harmful gas, germ, virus and less grit etc.).
It is worthy of note that nearly all miniature breath purifying device all belongs to disposable product, has not only once added user's financial burden, also wastes resource, contaminated environment simultaneously.
Therefore, be badly in need of at present a kind of broad-spectrum high efficacy, easy to use, comfortable generous, inexpensive, easily reusable miniature respiratory clarifier satisfies the numerous common people's demand.
Summary of the invention
The respiratory clarifier of introduction of the present invention exactly satisfies above-mentioned demand, have flexible combination, convenient use, high-efficiency broad spectrum, comfortable safe, automatic Bao Gu, easily activation, repeatedly available, economical and practical, save advantage such as resource.Various advantages of the present invention realizes by following design:
The core component of this device is one group of efficient filter disc that respectively different nuisances is had the high air penetrability of particular purification function, can purify demand according to difference and targetedly several filter discs are used in combination, deal with various breath purifying demands by the light combination of multiple filter disc.It both can combine with a kind of miniature elastic clarifier accessory that this explanation provides, constitute nasal respiration clarifier attractive in appearance, comfortable, stealthy, wide spectrum, also can make the needs that mouth mask, face shield, the helmet, ose bag or other form respiratory clarifier satisfy different groups.
Described miniature elastic clarifier accessory can seal hidden cover (100), elasticity filter disc fixed support (300) and nose immobilising device (400) etc. by clarifier and form.
Gas purification filter disc group is the purification filter disc combination of selecting for use at different environment, it is the efficiently airborne dust of filtering, pernicious gas (as sulfur oxide, carbon monoxide, formaldehyde etc.), various bacterium (as the pulmonary tuberculosis germ etc.) and virus (as influenza virus etc.) not only, also have automatic Bao Gu simultaneously, easily characteristics such as activate, can use repeatedly, thereby reduce user's consumption burden greatly, save resource, reduce the pollution of refuse abandonment environment.Especially it is worthy of note, aspect sterilization and disinfection, the present invention has adopted the surface to have the high penetration multistorey strainer mesh of silverskin (or stabilized nanoscale silver) to replace the traditional soup immersion or the material of doping metals nano-powder, can guarantee efficiently to remove harmful microorganism, the potential threat of simultaneously having avoided soup in the existing product or nano-powder may enter body, health risk again.Aspect pernicious gases such as filtering indoor and outdoor formaldehyde, carbon monoxide, the present invention has adopted supported catalyst (as Pt/TiO
2Deng) the multistorey strainer mesh that interlaces of grid it at room temperature is converted into nontoxic carbon dioxide rapidly.
It is a kind of have favorable elasticity and sealing that clarifier seals hidden cover, size, profile and color and luster are equal to the parts of (or approaching) people nose outlet outline (need not emphasize color here, because it is not necessarily attractive in appearance with other color yet, particularly to the young man), be characterized in: can be hidden in it purifying filter disc, can be fine sealing purify the seam that filter disc and nose export, promote the breath purifying effect, simultaneously because the good skin compatibility of its material, even long periods of wear also can not cause the discomfort of skin.In order to realize the stealthy effect of clarifier, this seals that hidden cover contacts with nose can be by following two kinds of forms: one is that its integral body is close to nose and exports the outer end, seems the extension slightly of nose portion; Its two, be when itself and nose are close to, in some recessed nostril (or being hidden under the nose).Certainly in addition, other class way of contact can be arranged also, purpose is when guaranteeing that sealing purifies filter disc and nose slit, and latent type effect is provided, and makes difficult being discovered when wearing and influences attractive in appearance.
Elasticity filter disc fixed support (300) be shape arbitrarily, certain elasticity and intensity are arranged, temporary transient elastically-deformable stereoplasm frame can take place repeatedly or have the thin net of hard housing.Elasticity filter disc fixed support (300) partly or entirely can be by metal of the same race or not of the same race, natural polymer is (as wood, bamboo, bone etc.) or artificial macromolecule (as synthetic rubber, plastics etc.) material preparation, its effect is under acting synergistically with the nose immobilising device, provide the flexible sealing support of exerting pressure to the air cleaning filter disc together with the hidden cover of sealing, make it under the situation of no breath pressure, to be close to the nose lower end, guarantee to suck air and only enter nasal cavity by filter disc, but when running under the bigger breath pressure effect, temporary transient elastic deformation takes place, allow filter disc to separate (or allowing the hidden cover part of filter disc and the sealing on being fixed on the nostril to separate) with the nostril together with the hidden cover of sealing, it is unblocked to guarantee to exhale, and has overcome the not smooth technical bottleneck of expiration that existing rhinobyon type purifier exists.

The specific embodiment
This device is by the core of clarifier---gas purification filter disc group (200) and accessory---, and clarifier seals hidden cover (100), elasticity filter disc fixed support (300) and nose immobilising device (400) etc. forms.Each the parts color that constitutes this class clarifier can have multiple choices according to the colour of skin of different people, and its profile and size should export profile phase with (or close) with nose, makes it to be difficult for being discovered when wearing.
Detailed directions is (shown in Fig. 4-A, 4-B and 4-C): at first, the filter disc of choosing (200) is embedded in the hidden cover of sealing (100) in certain sequence successively together with elasticity filter disc fixed support (300), constitute a stealthy respiratory clarifier (100+200+300); Secondly, the opening part by stealthy respiratory clarifier middle part penetrates nose immobilising device (as nasal septum folder (330)); Then, the nose immobilising device is clipped on the nasal septum (or otherwise being fixed on nose); At last, the stealthy respiratory clarifier that is fixed on the nose is pushed gently to nose, export with nose fully up to the hidden cover of sealing wherein (100) part and be adjacent to sealing and get final product.
It is to be noted, only be to allow the reader of common level can understand and put into practice the principles of science of present patent application and the schematic part illustration that characteristics provide about description, the example of clarifier and the diagram that provides herein, but be not that our invention of limitation is in this, as Fig. 4-A only is in order to help a given combination special case of reader understanding's principle of the invention, in fact, this class breath purifying device can have multiple assembling mode, and this paper can't give unnecessary details one by one.Air cleaning filter disc group of the present invention (200) not necessarily only is fixed on nose by nasal septum folder (330), also can bond, be set in the ose bag or be set in other class respiratory clarifier and bring into play breath purifying function by nose limit folder, resilient sleeve, adhesive plaster.In practice, also breath purifying filter disc size of the present invention can be amplified, make mouth mask, satisfy the crowd that the part custom is breathed with mouth.Varied nose (or mouth) breath purifying device design of any the principles of science that provides based on patent specification and products characteristics (include as size, thickness, filter disc structure, the clarifier of the shape of compound mode, bracing frame of the number of plies of porous thin slice and shape, filter disc and sealing shroud built-up sequence, with the fixing mode of nose, used material etc.) all belong to a part of the present invention.
It is to be made by rubber, plastics or other materials with certain intensity, elasticity, excellent sealing and skin compatibility that clarifier seals hidden cover (100), it both can be hidden in it with gas purification filter disc group (200) and elasticity filter disc fixed support (300), make it when wearing, not affect the appearance, simultaneously the outer means of press seals of being executed by nose fixture (as nasal septum folder or other) and the fixing back of nose again seals the slit between hidden cover and nose, guarantees that suction gas can only enter nasal cavity by the filter disc aperture.
It can be by the reversible deformation of part can take place but still have the horizontal stereochemical structure of certain rigidity shown in Fig. 1-A, Fig. 1-B and Fig. 1-C that clarifier seals hidden cover (100), also non-level part can be ensconced the flexible sealing stereochemical structure of (and/or under nose) in the nostril, can also be other stereochemical structure that plays packaging effect.
When clarifier seal hidden cover (100) shown in Fig. 1-A, Fig. 1-B and Fig. 1-C, the reversible deformation of part can take place but still have the horizontal stereochemical structure of certain rigidity, this hidden cover (100) has following structure and (sees Fig. 1-A): seal hidden cover outer wall (101); Seal the gasket seal (102) that hidden cover and nose are close to, its major function is to exert pressure down in that the elasticity filter disc is support bracket fastened, can play fine air seal effect, do not allow air slip from the slit into; Seal the air-vent (103) of hidden cover, communicate with the nostril, gas can only enter nasal cavity from this air-vent; Gasket seal opening (104) allows the nasal septum folder to penetrate; Seal the inwall (105) of hidden cover; It is to be noted, in actual design, when the filter disc that contacts with skin is when using the material preparation of skin compatibility, the structure that clarifier seals hidden cover (100) can be reduced to the high resiliency short tube that a bore is slightly less than the filter disc group, at this moment, above-mentioned 102-104 all can dispense from (100) structure.
The various filter discs that are included in the gas purification filter disc group (200) can be by chemically treatedly (or originally having certain chemical characteristic through special, as acidity, alkalescence, hydrophily, hydrophobic oleophobic etc.) inorfil (as asbestos, glass fibre, metallic fiber etc.), biomass fiber, synthetic fibers or blend fibre preparation, biomass fiber described here can be divided into living beings protofibre, living beings regenerated fiber two big classes substantially; Synthetic fibers described here can be divided into substantially with living beings to be the living beings synthetic fibers of raw material and to be the staple fibre (as polyacrylic acid etc.) of raw material with the polymer monomer; Here said blend fibre is meant the fibrous material by blending of inhomogeneity material or artificial grafting gained.
Here the various filter discs of indication both can be made by the thin net of one deck porous at least, also can be made of any flexible porous material of band (or not with) fine hair (as fur etc.).The shape of filter disc and size are answered similar or are slightly less than the profile that nose exports the termination, there is the opening that allows nose fixture (pressing from both sides or other as nasal septum) to penetrate at the middle part of filter disc (or other position), so that filter disc is fixed on support (300) and the nose, concrete aperture position can be different and different with the fixed form of nose because of clarifier.The thickness of single filter disc is decided because of need, is no more than 5mm usually, but can suitably thicken when special requirement.In addition, in order both to increase purification efficiency, do not influence comfort again, filter disc of the present invention has also adopted following way:
One is not influencing under the prerequisite of breathing comfort level, and the filter screen aperture of filter disc is dwindled as far as possible.On the broad sense, the mesh of filter screen can be between 100 nanometers-1 millimeter, but generally, and the mesh of selecting for use is between 500 nanometers-500 micron.
Its two, guaranteeing that the aperture of filter screen is not less than the diameter of netting twine usually, realizes the high penetration rate of gas with this under the as far as possible little prerequisite of mesh.
Its three, the fine-structure mesh by adopting high-intensity coarse net and low-intensity high purification alternately further increases the mechanical strength and the penetrating rate of gas of fine-structure mesh every the sandwich construction of folder.
Its four, the sandwich construction that interlaces by the filter screen grid increases as far as possible and sucks nuisance and the touch opportunity that each layer grid frame of adsorption function is arranged in the gas.
Fig. 2-the A of this specification has only showed a gas purification filter disc special case that is spliced by unlike material, and (200) are made up of filter disc opening part (203) three parts that filter gas thin slice (201), filter disc coupling part (202) and permission nasal septum folder penetrate at this moment.It is pointed out that in actual design filter disc also can be prepared by identical material, at this moment, above-mentioned (202) can be omitted from the structure of (200).
The filter disc that belongs to this breath purifying filter disc group (200) has: acid filter disc (210), alkaline filter disc (220), sterilization and disinfection filter disc (230), neutral filter disc (240), self-cleaning filter dirt sheet (250), the super filter disc of preserving moisture (260), catalytic oxidation filter disc (270) etc., when reality is used, can use single kind, two or more filter discs combinations according to purifying needs.
Described acid filter disc (210) is mainly used in filtering air neutral and alkali pernicious gas, positively charged dust and germ.
Alkalescence filter disc (220) is mainly used in deleterious acidic gas in the filtering air, electronegative dust and germ,
Sterilization and disinfection filter disc (230) is to have the inorganic or organic material net of stable metal film or metal nano (or micron) particle to construct by single or multiple lift metal, the surface of a class aperture in 100 nanometers-500 micrometer range.Metal described here is any noble metal (as silver, gold, copper etc.) or metal alloy that can pass through chemical reaction or physical action adhesion, bonding or modified microbe.For example when harmful microorganism when used argentiferous filter screen contact, the sulfydryl of microorganism and amino can the rapid and biochemical bonding of silver hair, stick to inactivation on the silver-colored surface.Microorganism described here is meant that size is less than 0.1mm and the tiny organism (as germ, fungi, virus etc.) that relies on organic matter to earn a bare living.Need special being pointed out that, for the high penetration and the comfort that can guarantee filter disc, do not reduce simultaneously filtering harmful microbe efficient again, when this safe and efficient sterilization and disinfection filter disc of preparation (230), the present invention has adopted the alternate sandwich construction of coarse net fine-structure mesh, both utilized the mechanical strength of macropore coarse net and at interval property promoted the bulk strength of filter disc and penetrating, the design that has also utilized multilayer fine-structure mesh grid to interlace simultaneously makes the gas that passes through contact with metal grill to greatest extent.
Neutral filter disc (240) is by the flexible material preparation that does not cause skin sensitivity, is generally used for contacting the filter internal layer of skin.This filter disc has three functions: the first intercepts contacting of other class filter disc and skin of nose, has both promoted the comfort level of use, can avoid allergic again; It two is the slits of playing auxiliary seal respiratory clarifier and nose lower end (or sealing shroud), prevent air slip from the slit into; It three is particulates emissions that further aided filter does not filter as yet fully.
Self-cleaning filter dirt sheet (250) is mainly used in dust in the filtering air.Be through super hydrophobic oleophobic chemical treatment gained, or prepare by organo-fluorine polymer.When using it for breath purifying, its fine and close grid and (or) lip-deep fine hair intercepts the dust that sucks on its surface, because the good oleophobic hydrophobic performance of this class material, adhering to the dust of its table can't stablize bonding with filter disc, be easy under air-flow of breathing or vibration effect, come off voluntarily, realize self-cleaning effect.
The super filter disc of preserving moisture (260) is through hydrophily chemical treatment (as with immersions such as glycerine, polyvinyl alcohol) or by the material preparation that contains a lot of hydroxyls, carboxyl, sulfonic group or phosphate in the structure.It is easy to from external world's absorption moisture and keeps certain humidity, when the pernicious gas in the atmosphere (as sulfur oxide, nitrogen oxide etc.) contacts with it and attempts to pass through, the nonvolatile acid of generation that can react with the water in it is stayed in the filter disc, in addition, moistening fiber environment is easier holds back the small dust that sucks in the gas, significantly reduces pernicious gas and dust to human body infringement and the allergy and the infection in respiratory system that are caused by breathing.
Catalytic oxidation filter disc (270) is made up of the filter disc that single or multiple lift can catalytic oxidation pernicious gas (formaldehyde, carbon monoxide etc.).This class filter disc can will be loaded with oxidate nano (or micron) particle of transition metal or noble metal catalyst (as Pt, Pd, Ni, Au, Ag etc.) by the mode of chemical graft or chemical bonding (as TiO
2, Al
2O
3, ZnO etc.) load on the gas purification filter screen.Pernicious gas (as formaldehyde etc.) by filter mesh layer and this class catalyst (as Pt/TiO2) can be broken down into nontoxic carbon dioxide and water rapidly when contacting.Current research shows, Pt/TiO
2Flow through wind speed 50000h at gas
-1, under the room temperature, can be the formaldehyde complete oxidation of 100ppm with concentration, even wind velocity lift is to 100000h
-1The time, also the formaldehyde of 97% same concentration can be converted into nontoxic carbon dioxide and water.
It is worthy of note that above-mentioned all kinds of breath purifying filter discs are not only disposable use, but can reuse, realize saving to greatest extent resource, reduce and pollute via simple and direct method activating and regenerating.As: the available clear water of the neutral filter disc (240) of inefficacy, self-cleaning filter dirt sheet (250) and the filter disc of preserving moisture (260) soak and slightly rub after dry and realize activation; The argent net (230) that lost efficacy can be sterilized, sterilize and be realized activating by a little light-coloured vinegar immersion or wiping; Acid filter disc (210) also can wash by light-coloured vinegar immersion and clear water regenerates; Alkalescence filter disc (220) can soak with soda water or light-coloured vinegar earlier, activates with clear water washing and heat drying then.Catalytic oxidation filter disc (270) can soak several minutes by boiling water, and heating, drying activates then.
Here the elasticity filter disc fixed support (300) of indication can be formed by connecting by nasal septum bridge (310), a pair of filter disc carriage (320), also can once make by machining, mold or alternate manner.Under specific circumstances, the nasal septum bridge (310) in the fixed support (300) can omit, and two filter disc carriages (320) can directly link to each other, the symmetric support frame that (320) are also little in the middle of, two is big.In another case, elasticity filter disc fixed support (300) also can be fixed together with nose fixed part (400), makes (400) become its part, as nasal septum folder (330).
This fixed support (300) is to be used to carry breath purifying filter disc (200), makes it when the user is air-breathing and the nostril is adjacent to, and only allows gas to suck by filter disc, and when exhaling, filter disc separates with the nostril together with its resiliency supported frame, and it is unblocked to guarantee to exhale.
Elasticity filter disc fixed support (300) partly or entirely can be by material preparation of the same race or not of the same race, available material comprises: metal, natural polymer (as wood, bamboo, bone etc.) or artificial macromolecule (as synthetic rubber, plastics etc.) material.
Nasal septum bridge (310) described here can be thin slice, short tube or the stub of single bridge, doube bridge or many bridges, and its length should be between 1mm-1cm.Its effect is to be used to connect filter disc carriage (320) and nasal septum folder (330), makes it to constitute a complete elasticity filter disc fixed support (300) that can be fixed on the nose.
Filter disc support frame (320) is arbitrary shape, certain flexible stereoplasm frame is arranged or have the thin net of hard housing, and the size of framework should be close with the periphery, nostril.This links to each other to filter disc carriage (320) and nasal septum bridge (or bridge group) (310) two ends symmetry, and constitutes certain angle with (300), formation hand root (or hand point) continuous to the palmate structure.Its effect is under acting synergistically with the nose immobilising device, provide the flexible sealing support of exerting pressure to the air cleaning filter disc together with the hidden cover of sealing, make it under the situation of no breath pressure, to be close to the nose lower end, stop air from slipping between filter disc and slit, nose lower end, but when running under the bigger breath pressure effect, the outer end of framework can be separated with the nose lower end again with sealing shroud together with filter disc, allows the interior waste gas of body to overflow from opening part.
Here the nose immobilising device (400) of indication can be nose (in) every folder (330), limit, nostril wall folder (410) or other class and nose fixture (as adhesive plaster bonding, elastic webbing, ose bag etc.).The nose immobilising device (400) of nose clip class can be by having the metal, plastics of favorable compatibility or other that certain flexible hard material preparation is arranged with skin, it both can become the part (330) of elasticity filter disc fixed support (300), also can be used as the assembling that individual components (400) is used for clarifier.One of effect of the nose immobilising device (400) of nose clip class is by penetrating or method such as embedding is fixed on air cleaning filter disc (200) on the fixed support (300) together with the hidden cover of sealing (100); Two of its effect is to be connected with the tight of nose by it, will seal hidden fixed support (300) of hidden cover (100) and filter disc group (200) and be fixed on the nose exit.
When the nose immobilising device (400) of nose clip class becomes elasticity filter disc fixed support (300) a part of as nasal septum folder (330), nasal septum can be pressed from both sides (330) and be fixed on the nasal septum bridge (or filter disc carriage), its can be collapsible curve clamp (or intermediate plate) of inverted U (or other arbitrary shape) of (maybe can not fold).This to curve clamp (or intermediate plate) can be parallel over against, also dislocation relatively, or by regulate this to the yardstick over against curve clamp one be slightly less than another make clamp (or intermediate plate) can misplace folding, save parking space.
