Abstract
The cap type inflating valve consists of mainly one inflating needle, one air needle sleeve, one pressure spring and one sealing ring, and the inflating needle and the air needle sleeve may be two plastic parts or two metal parts.
Description
The utility model relates to when a kind of inner tube of a tyre to installation air needle type admission piece puts on the air need be installed at the charging connector that plays interconnect function between admission piece and the inflator chuck, belongs to the inflation of tire field.
When the inner tube of a tyre that has the air needle type admission piece that uses in the vehicle now is put on the air, a charging connector need be installed between inflator chuck and admission piece, the charging connector that uses mainly contains coventional type and Anti-leakage type at present, coventional type charging connector volume is less, when being connected with inner tube of a tyre admission piece, its front end just backs down the choke thimble in the inner tube of a tyre admission piece charging connector is communicated with the inner tube of a tyre, at this moment, must connect the inflator chuck very soon and inflate, otherwise can be with the gas light leak in the inner tube of a tyre; After the gas abundance, must earlier charging connector be taken off from admission piece, otherwise also can cause gas leakage, so use inconvenient.The Anti-leakage type charging connector is provided with the switch that backs down the choke thimble, can be before inflation or inflation after switch cuts out can prevent gas leakage, but exist volume big, cost shortcoming high and that damage easily.
The purpose of this utility model is in order to overcome the weak point of above-mentioned existing charging connector, design a kind of simple in structure, volume is little, air tight, hat type charging connector that productive costs is low.
Hat type charging connector of the present utility model, comprise top air tube, seal ring, air tube cover and stage clip, described top air tube is contained in the air tube cover, air tube lower end, top sidewall has an aperture to communicate with its upper end, air tube top, top has outer shoulder and air tube cover top to match, air tube cover middle part has an interior shoulder and air tube bottom, top to match, compression spring sleeve interior shoulder and outside on the top air tube between the shoulder, air tube lower end, top is thick and be contained in shoulder below in the air tube cover, the negative thread that matches with the inflation of tire mouth is arranged at air tube cover bottom, and seal ring is contained in the top of air tube cover negative thread.
Accompanying drawing is a structural representation of the present utility model.
Referring to accompanying drawing, 1 among the figure is the top air tube, the 2nd, and air tube cover, the 3rd, stage clip, the 4th, seal ring.Wherein air tube 1 lower sides in top has an aperture 5 to communicate with its upper end, top air tube 1 is contained in the top of air tube cover 2, air tube top, top has outer shoulder and air tube cover top to match, air tube cover middle part has an interior shoulder 6 to match with air tube bottom, top, on the top air tube in stage clip 3 is enclosed between shoulder and the outer shoulder, air tube lower end, top is thick and be contained in the below that air tube overlaps interior shoulder 6, and the negative thread 7 that matches with the inflation of tire mouth is arranged at air tube cover bottom, and seal ring 4 is contained in the top of the negative thread 7 of air tube cover.After guaranteeing that the inflator chuck is contained on the charging connector, the top air tube can back down the choke thimble on the tire admission piece, and during design, 2-5MM should be able to be stretched out to the below of seal ring 4 in air tube lower end, top.During production, air tube gentle needle guard in top forms with the plastics compacting or with metal car system.During installation, with the compression spring sleeve air tube cover of packing into after on the air tube of top, its lower end shoulder 6 in the air tube cover middle part is stretched out and air tube lower end, top hammer is thick by the air tube upper end of bearing down on one, thick as can air tube lower end, top being scalded with the blanching method for Plastic Parts, make it to be overlapped the bottom by interior shoulder 6 retainings at air tube, the top that at last seal ring is contained in air tube cover negative thread gets final product.During use, air tube is overlapped on the admission piece that lower thread 7 is tightened on the inner tube of a tyre, at this moment, the lower end of top air tube 1 is contracted between the downside of the interior shoulder 6 of air tube cover 2 and seal ring because of the elastic force of stage clip 3, therefore, inoperative to the choke thimble in the tire admission piece, so do not produce gas leakage; When inflating, the chuck of inflator is clipped in the lower end of air tube upper end, top and air tube cover, because of the folder power of chuck moves down the top air tube, at this moment, 2-5MM is then stretched out to the below of sealing baa in air tube lower end, top, just in time the choke thimble in the tire admission piece is opened and inflated, when taking off the inflator chuck after inflation finishes, the lower end of pushing up straight air tube automatically returns to the seal ring top again and can not cause gas leak phenomenon.Because volume is very little, can directly be contained in double as gas nozzle cap use on the tire, as on the air tube of top, overlapping then better effects if of a dust cap again.
That cap type pneumatic probe puffing opening of the present utility model has is simple and reasonable, volume is little, the life-span is long, no Leak gas, portably use conveniently, also can directly be contained in advantages such as doubling as the gas nozzle cap use on the tire, be fit to and each The air needle type inner tube of a tyre of planting vehicle supports the use.
