New type of safe, cleaning, convenient Floor Pump

Affiliated technical field

The utility model relates to the design and the manufacturing technology field of manual pump and air pump safety charging connector.

Background technology

For these years, upper reaches, market row general-duty manual pump nearly all is " set from birth, unalterable ", and using till today does not still have much variations.Along with era development, the improvement day by day of people's work, living condition, it is obvious all the more that the inconvenience that exists in its use also just seems, particularly for those white collar working clans of brothers' " dust does not dye, greasy dirt be not stained with " all day long, is reluctant to do this " dirty hard job " especially.But light and handy, the convenience of bicycle itself, body-building, leisure make its short distance that is still most working clan first-selection of riding instead of walk.Especially under the influence of the world of " environmental protection, energy-conservation " two big current first concerns theme, existing at present quite a lot of national government are more actively advocated, are advocated citizen and adopt the bicycle short distance to ride instead of walk, and have formulated a series of relevant encouragement policieies, policy for it.As seen, bicycle is still the life necessary article of human society Future Development, now so that in the future, bicycle still can occupy the very big market share.In a word in short, as long as bicycle exists, Floor Pump just has very big potential market, is exactly the essential articles for use of people's daily life institute, and still more, present " supercharging Floor Pump " its inflation pressure can surpass 1Mpa, the tire pressure that can satisfy power actuated vehicle fully is required.Obvious, design and make a kind of novel Floor Pump that can adapt to the integrating of New Times demand " safety, clean, convenient " and be " epoch compel, situation required ".It will replace tradition and inflate pattern, wins that the user is pretty to be looked at, and dominates the market, and becomes bicycle, car user, even body-building, amusement, physical culture occasion is indispensable first-selected.And so-called at present " electricity is inflated ", that is: air pump is inflated, though can economize many things, its existence carry inconvenience and the source of the gas dynamical problem still makes it can't substitute manual pump, there is a potential safety hazard in it still more.That is: automatic guidance inflation pressure immediately " is pinched while filling " by rule of thumb by the user often, and for the air pump that aeration speed is exceedingly fast, this mode often is difficult for accuracy control.Current quite a lot of vehicle repairing store is in order to raise the efficiency and to make things convenient for the user also to be equipped with air pump, its practical high-power air pump is directly inflated cycle tyre, this is absolutely unsafe, because the pneumatic volume of cycle tyre itself is little, tire pressure requirements is low, be difficult to reach disposable accuracy control, the inflation overload very likely occurs, must " put " after this makes quite a lot of people inflate often to finish while pinching.For the conventional manual Floor Pump, the user especially " beat must put down inflator touch with hand and pinch tire, whether suitable " with the sensing tire pressure a little while, such operating mode is inconvenience and being inaccurate extremely, can only be with the qualitative sensing of my intuition, and be to be reluctant the one procedure done in the field feedback most, trouble is not said " one pinches two hand soil ", especially under steam this thing appears in the way, can't find the place of conveniently washing one's hands again, the user can only be " dirty two hands of soil, awkward and go ".Although occurred " oppositely sleeve " constitutional formula inflator pump in the market, basically solved the shortcoming that Floor Pump piston rod in the past exposes the greasy dirt clothes, and the high-pressure pump of steam supply vehicle tyre inflation usefulness has also been installed compression indicator, but it only is simple reading, can not accurately realize automatic guidance and warning function immediately, still fail thoroughly to address the above problem.In addition, at present the inflated hose structure of Floor Pump is also not ideal, and pendulum shakes, and deposits inconvenience and always drags on the ground, makes whole flexible pipe and charging connector dust dirt all over the body, allows cleanly people be reluctant to contact this charging connector at a glance.In a word, traditional Floor Pump and the pattern of inflating allow " inflate operation " to iron deep together branding in people mind---one not too efficiently, the work post be engaged in of " white collar, beauty " inconvenience.The author just is being based on above-mentioned all same feeling, deep experiences, is subjected to its hardship deeply, just excites this inspiration intention, just is " required because of forcing, arise at the historic moment ".

Summary of the invention

In order to overcome above-mentioned defective, the utility model provides a kind of sanitation and hygiene, safe ready, accurate simple and direct novel Floor Pump and air-pump inflating mouth, to adapt to times flavour, cater to modernization popular " mouthful stomach ", real realization omnibearing " cleaning inflation ", thoroughly smooth traditional Floor Pump and deep branding that the pattern of inflating stays people in the heart, offer as a tribute the New Times Floor Pump of a kind of " loved by all, everybody accept ".

The technical solution of the utility model is to realize like this, its fringe cost is cheap, implementation process is extremely simple and practical, only need to set up an adjustable pressure limiting valve at conventional manual Floor Pump gas off-take and air pump outlet nozzle place, just can guarantee when tire pressure reaches predetermined value, to lose heart automatically rapidly immediately and warning simultaneously, for kinetic pump, also but the immediate feedback signal is by losing heart, to save energy consumption.It has simplified " pinching while beating " operation in the past, makes tire pressure control quantitative digitalization, improves precision greatly, disposablely finish smart amount inflation, has cancelled the user and has been reluctant " pinching tire " link of doing most.For inflated hose and charging connector.Then adopting can retraction type conceptual design, has overcome defectives such as the swinging of traditional inflated hose, occupation of land, pollution.

The utility model has the advantages that: environmental protection rational in infrastructure, simple to operation, clean, safety accurately, be easy to implement, cheap, only need improvement a little on existing Floor Pump basis, can realize repertoire.This inflator structure compactness, moulding are refined, appendix does not bounce back automatically the time spent, access is convenient, this behavior of structure of while makes its whole center of gravity concentrate and moves down, and increases vertical stability, and very easy assurance stack shell is upright to be placed or the suspension placement, thereby make barrel protect cleaning forever, refined, fashion are changed the unhygienic image of traditional inflator " accumbency is indulged and put, dirt is in the way ", improve the taste of inflator personal value class and customers' consumption psychology.Main person: its operating process is extremely simple and efficient; before the use; the user only needs to check the air pressure dial plate according to vehicle type and summer and winter temperature situation in advance; as not being inconsistent with own situation; should stir the knob set position earlier; then just can relievedly inflate; the disposable gas replenishment process of accurately finishing tire; just lose heart automatically when reaching predetermined value and report to the police; whole link user at all needn't contact tire, and can guarantee that tire pressure reaches optimum regime, needn't go rough by rule of thumb perception; this preceence also is to protect tire, prolongs tire service life.For air-pump inflating person and the bicycle person of inflating; after this safe protective arrangement for limiting output voltage has been arranged; the user needn't worry to take place " danger of blowing out "; greatly can relieved disposable " being inflated to the end "; automatic immediate is disappointing when reaching the air pressure ideal value reports to the police; and, realize full-automatic aeration (also can not add this feedback valve) simultaneously by source of the gas.

The specific embodiment

Figure 1 shows that adjustable pressure limiting valve principle of work structural representation, during use, only the hickey at its two ends need be connected in series in common Floor Pump and the air pump gas path pipe and can satisfy use, reach pressure limiting inflation purpose.This limiting valve is provided with manual voltage regulation knob (1), pointer (2), pressure regulation dial plate (3), before the inflation, earlier select suitable gear according to vehicle type and current temperature situation, just can relievedly inflate then, siren (4) is housed on this limiting valve, when inflation pressure reached predetermined value, siren just can be reported to the police (2) at song under the popping pressure, informs that the user inflates end (this limiting valve can be selected gauge member for use).

Be illustrated in figure 2 as this limiting valve pressure regulation dial plate schematic layout pattern, this friendly interface, to give the natural cordial feeling of a kind of closeness to life of user than the inflation pressure value spoken and written languages popularization of specialty, any one is as long as the user friend of character learning can both correctly grasp, skillfully use.In addition, this card is further refinement also, the unit pressure value of demarcation next case of temperature before single, so that allow the user that different parking stalls tire is carried out the different pressures inflation and measures current tire pressure, the dial scale sector also can by temperature by height on earth order be designed to the seven color excessive naturally rainbow looks of " the yellowish green indigo purple of blood orange " successively, the sign symbol of implicit a kind of four seasons spring, summer, autumn and winter temperature Change, cordiality elegant in appearance, directly perceived.In addition, also can further increase on this dial plate such as three-wheel vehicle, boosted vehicle, to cater to customers' consumption psychology, win the market in Different Weight level bogie and the special-purpose scale fan of inflatable appliance road such as ball.

Fig. 3 more piece bendable fold-type appendix arrangement structure scheme drawing of doing substitutes existing rubber tube with this bendable fold-type hard tube, and advantage is that its degree of freedom anticipates with the people, think how just how curve, the time spent replication locks to appendix clip (8), can arbitrarily not swing, and it is agile to deposit the convenience of taking.In addition, the utility model is designed to two ends band hook type with Floor Pump handle (7), can safely inflator be hung and deposit, this inflator is after appendix buckles in the clip (8) locking, whole inflator just becomes an integral body, piston rod can freely not extend by by gravity, is convenient to hang deposit, and can establish a special small and exquisite hook (6) in addition yet and be convenient to be mounted on other specific occasion on barrel.

Figure 4 shows that 3 D auto degree soft or hard combination swing pipe arrangement structure scheme drawing, this scheme realizes being connected with the object to be inflatable valve at place, arbitrary locus by the attached a bit of flexible pipe of the hard tube that can freely swing in the three dimensional space, compact conformation, couple hardness with softness, bring out the best in each other, swinging fast freely, is in another moulding of drawing on the last scheme advantage basis.

Figure 5 shows that body rotary type coiled coil appendix arrangement structure scheme drawing, it changes on the advantage basis of original soft appendix further, after inflation finishes, soft appendix can freedom circles round fast and tightly coils around barrel, compact firm, eliminated the shortcoming that traditional inflator always drags Great Wall Software's pipe.For guaranteeing normally carrying out and being connected of coiled coil with inflator the reliable of base of giving vent to anger, this scheme has adopted inflator give vent to anger base and pedal bottom plate separated structures pattern, be connected by the end spring (16) that resets between the two, this makes its stack shell when pulling out inflated hose also can rotate thereupon, and this is the inconvenience (hereinafter scheme has remedied this point) of this inflator.Spacing moving sets sliding sleeve of appendix (13) and two-dimentional revolute pair (14) retrain the location to appendix among the figure, be guarantee flexible pipe realize normal disk around the constraint annex, in addition, also can adopt the secondary formula of long narrow slit type or telescopic moving to substitute two-dimentional revolute pair (14) flexible pipe is retrained location (seeing Fig. 5 top accompanying drawing A, B for details).

Fig. 6 is reverse helical spring type appendix arrangement structure scheme drawing, it adopts elastic reset reed pipe (17) and appendix to merge the structural pattern of one, after pulling out appendix during use, the one section inflated hose (15) that just is coiled on the rotation distance sleeve (18) stretches out, the one section breather pipe that merges one with elasticity reed pipe (17) then is not drawn out, it only is that elastic deformation track with reed pipe is subjected to displacement, thereby guaranteed the one perforation of gas circuit with the chassis of giving vent to anger, do not influence rotatablely moving of top flexible pipe again, for reducing rotate flexible pipe partly and the wearing and tearing of barrel generation slide relative, distance sleeve (18) is set up in the centre, there is not slide relative between distance sleeve and flexible pipe, connect and form a revolute pair with air cylinder wall, in this revolute pair gap, can form lubricant film, reduce wearing and tearing and damping by modes such as design oil leab and oil grooves.

Fig. 7 and Fig. 6 difference are that Fig. 6 adopts reverse joint will rotate extended flexible pipe part (15) and the elasticity non-sponson (17) that reverses and is connected, change it and curled up direction, thereby the retraction normality that resets of (17) is a kind of state that tightens to make elasticity reverse partly, that is: only stretch out in the use at the top flexible pipe, helical spring (17) just is in diffusion tension and relaxation attitude, in case use up then tightly bounce back around barrel, volume is small and exquisite, is convenient to deposit.

Figure 8 shows that built-in inflation cast stretcher arrangement structure scheme drawing, it is creatively with inflated hose and the fit place of stretcher, form similar tape measure theory structure pattern, save the space more, elegant in appearance, neatly agile, exquisite portable, its another advantage has been to eliminate the reactive torque of retracing spring generation and the interference of tubular axis, thereby makes torque axis turn to system's internal force, do not manifest torque characteristics to external world, user-friendly, use.(after the hiding built-in mode of inflated hose employing, should select the non-resilient flexible pipe of high-intensity fine footpath thin-walled for use as far as possible, be taken up space) further to reduce.

Fig. 9, Figure 10, Figure 11, Figure 14, Figure 15, appendix version shown in Figure 180 all can be taked this to be hidden in stretcher in-to-in mode to design, Fig. 9, it is reverse that Figure 10 is respectively, clockwork spring retraction type appendix arrangement structure scheme drawing forward, this scheme and Fig. 6, scheme difference shown in Figure 7 is, it is compressed in its solid space structure in the two dimensional surface and arranges, compact conformation, be convenient to be built in the stretcher, so, be further reduced volume, inflated hose adopts in this scheme does not have flexible flexible material manufacturing, (also can adopt the double-layer composite material manufacturing), this material has that can flattening after losing heart reels to be deposited and high pressure resistant, characteristics such as nonelastic deformation, allot the stripe shape wind spring is slim spring in addition, then can greatly reduce volume through such combination, dwindle taking up room, with appendix as metallic tape, the coiling compressed storage can satisfy the designing requirement of depositing in the stretcher well.

Adopted rotatable type gas circuit sealed interface spare in the structure shown in Figure 11, solve relative rotation and gas circuit and sealed the conflicting of the two, thereby cancelled appendix parallel among Fig. 9, Figure 10 with the clockwork spring one, saving length is over half, reduced volume is more conducive to optimize the moulded design of inflator greatly.

Figure 12, Figure 13 are respectively two kinds of rotatable seal joint spare structure principle charts, adopt stage clip (29) to seal ring (28) precompressed among Figure 12, at first connector (27) seal face is sealed, when pulling out the appendix inflation, seal ring (28) just under the inflation pressure effect tightly pressing in the interface of giving vent to anger (26) seal face, constituted one dead front type annular seal space thereby giving gives vent to anger between interface (26), the intake interface (30), finished closed gas-flow and carry.

Structure shown in Figure 13 is more succinct, the coiling that its sealing principle is ingenious when having utilized the pull appendix rotatablely moves, this path of motion is drawn the interface (26) of giving vent to anger, intake interface (30) relatively rotates, when all pulling out appendix, then the two screw thread just in time is rotated in place, thereby pinch-off seal circle (28) forms annular seal space.

Figure 14, Figure 15, Figure 16 shows that the assembly pulley frame-type telescopic appendix structural principle scheme drawing that floats.Figure 14, structure shown in Figure 15 all can be built in the stretcher, as shown in the figure, when tension appendix free end, to overcome spring elastic force under the effect of inflated hose tractive force close mutually for two groups of assembly pulleys up and down, thereby with a large amount of built-in appendix outputs, the former is a transversal stretching, and flexible yardstick is less, the latter is longitudinal extension, and flexible yardstick is bigger.Figure 16 shows that coiling type space structure, obvious from schematic diagram, be characterized in that storage space is big, can shrink existing soft appendix and deposit.In above-mentioned several scheme, also visual its resistance to abrasion, conditions such as life-span are removed assembly pulley, and are directly lubricated by interaxle slip, finish working condition requirement, and simplified design is dwindled the space.

Figure 17 shows that gravity drop hammer homing position type structure, its advantage is, retraction force remains constantly, and with low cost in pull appendix overall process, and not fragile, the life-span is permanent.But its usage condition is: homing action must just can be finished under upright state, and increase the inflator overall weight to a certain extent, so also can adopt the human intervention type, promote handle (38) with manual or foot-operated action and affect assembly pulley to be separated from each other, finish the retraction process of inflated hose.

Figure 18, mechanism shown in Figure 19 are groove engagement retraction type, and its advantage is that appendix does not participate in and rotatablely moves, and groove type appendix (40) and pinch roller (39) initiatively present the meshing relation of similar rack-and-gear by the groove engagement, and displacements of the lines such as realizations are moved.When pull appendix (40), just affect pinch roller (39) motion like this, synchronous recording the discrepancy stroke of appendix, and the wind spring that is reset (42) stores with elastic potential energy, reclaims the appendix homing action so that finish.

List three kinds of control lockout mechanisms among the figure (19) altogether, select one to get final product during enforcement, its process is summarized as follows respectively: (one) draw-in groove locking type: by spline draw-in groove (45), spline groove (48), stage clip mechanisms such as (43) forms, when inflated hose is all pulled out, at the appendix afterbody a bit of short and thick hard tube district is arranged, both sides reseting pressuring spring (43) compression and promotion simultaneously initiatively move on the pinch roller (39) up and down simultaneously to guarantee reliably to compress ingear, so spline groove (48) and draw-in groove (45) engagement, thereby play the spline locking action, at this moment, indicateing arm (44) appears from the hole, informs that Subscriber Locked puts in place.After inflation finishes, press reset button (47), traction contact roller (41) moves down, and spline draw-in groove (45), spline groove (48) separate under top stage clip (43) effect, and locking is removed, so reclaim inflated hose under the wind spring that resets (42) effect.(2) boss block locking type: by spline boss (49), spline block compositions such as (46), this scheme advantage is can be at stretching half-way locking, totally 4 of spline boss (49), divide 90 degree to arrange that at interval pinch roller (49) whenever turn 90 degrees just a locking position, it is handy to operate.After inflation finishes, press reset button (47 '), move on the traction spline block (46), spline boss (49) locking is removed, so reclaim inflated hose under the wind spring that resets (42) effect.(3) unidirectional voussoir locking type: this structure has more advantage, can realize being close to the stepless locking of optional position, and simple in structure, superior performance is the suggestion first-selection in above-mentioned three kinds of schemes.Voussoir (50) has unidirectional locking, and appendix can be gone out can not be advanced, and must press reset button (47 ") when bouncing back appendix in advance.(annotate: each appendix that relates in the utility model reclaims in the embodiment, all contains the locking detent mechanism, introduces in the lump at this, and other places are no longer mentioned.)

Figure 20 is a free expansion spring retraction type appendix structure principle chart, and its advantage is that Installation and Debugging are simple, parts are few, with low cost, and only a coil spring (51) adds a constraint housing (53) and gets final product.The built-in inflated hose of coil spring (51) hollow space (32), its similar is in the traction backguy of bicycle brake, but difference is, this coil spring (51) can freely stretch, so just formed compressible elastic space, limited diameter through hole (52) only allows appendix (32) freely pass through and spring (51) card only is bound by within the housing (53).Before the inflation, pulling inflated hose (32) is compression spring (51) then, so it reduces around radius, interior space reduces thereupon, and appendix stretches out in housing.After inflation finishes, unlock, then spring (51) free expansion is uniformly distributed in housing (53) inwall constraint circle circle, and interior space increases, and again appendix is retracted spiral spring (51) inside, finishes the retraction that resets of appendix.

Annotate: the tracheae concertina type structure that this paper provides is equally applicable to other industry, and the various different field of this technology category of all genus all belong to this patent property protection domain.
