Abstract
The utility model relates to a tyre inflating valve parts which is suitable for the tyre inflating valve parts of motor vehicle and non-motor vehicle. The utility model mainly comprises an inflating mouth, a screw cap, an inflating seat, a sealing rubber bushing, a locknut, a pad piece and a parallel-tightening nut. The utility model has the advantages of the reduction of the tyre inflating valve parts, reasonable design, simple manufacturing technique, low cost and convenient use, labor saving about 65% less than that of the former, long rubber exchanging term and being easy to clear the dunghill in the inflating valve.
Description
The utility model tire inflatabling nozzle assembly is suitable for doing motor vehicle, non power driven vehicle and makes tire inflatabling nozzle assembly and use.
The inflating tyres of vehicles assembly has two kinds of structures at present: a kind of motor vehicle charging air inlet assembly, the complex structure of this charging air inlet, processing technology difficulty, cost of production height; Another kind is a rickshaw tire charging air inlet assembly, and this charging air inlet adopts the projection bag to seal, thereby the caulking gum pipe destroys easily in sealing part, thereby loses sealing effect.The reason that damages is crossed thin and local pressure break mainly due to the sealing part rubber, be on the other hand when inflation air-flow flow backwards and make the sealing part rubber produce stress to concentrate and break, thereby lose sealing, cause gas leakage slowly.This charging air inlet is changed rubber and is not easy, and need cross convex closure because of filling up when mouth has convex closure dress rubber, is difficult for changing.Effort and easily cause sealing part rubber stress to concentrate during inflation, because the charging air inlet head is long, the female surface of rubber and charging air inlet head is excessive, thereby effort when causing inflating, and gas flows backwards, and causes stress to concentrate, and the sealing part rubber is broken, not easy to clean of foul is arranged in the charging air inlet, be about to scrap if foul stops up.Inflation seat sealing surface is darker apart from oral area, and rubber is if rot in inflation seat sealing part, and bad rubber is difficult for removing.Because this charging air inlet, inflation seat are complex-shaped, processing technology is poor, and stock utilization is low, thereby has increased processing cost.
The purpose of this utility model provide a kind of reasonable in design, simple in structure, be convenient to process, the novel tire inflatable component of easy to use, good airproof performance.
Tire inflatabling nozzle assembly takes following scheme to realize: main structure is made of charging air inlet, nut, inflation seat, caulking gum sleeve pipe, locking nut, pad, fastening screw nut.Charging air inlet is having very big change in shape, and cylindrical structure is adopted in the cancellation of sealing surface convex closure, and head shortens, and air outlet hole changes two-sided through hole into by the single face hole.Flanged surface is processed in the outer end, has cancelled two shoulder muscle, and the charging air inlet center is processed with a circular hole, outer end flare taper hole, and the bottom is a cylindrical hole, to reduce intake resistance, is convenient to concentrate air inlet.Overall length shortens than former valve.Inflation seat sealing surface is located at head, and the head endoporus has step, and step is processed with the endoporus that has conicity and makes sealing surface.Inflation seat external process has screw thread, is used to assemble locking nut, fastening screw nut, nut, and is processed with wrench clamping mouth.The caulking gum sleeve pipe is having taper shape or arc cam with inflation seat sealing part, and the bottom is a tubular shape, is used to seal air outlet hole.Adopt the caulking gum sleeve pipe of the new shape of this practicality, Sealed valve is difficult for breaking, good sealing effect.
During use the caulking gum casing pipe sleeve is contained on the charging air inlet, puts into inflation seat, adopt nut locking, loosening for preventing charging air inlet, with and cap and tightly on the inflation seat, can be to tyre inflation.
Tire inflatabling nozzle assembly is similar to the charging air inlet assembly of former non power driven vehicle, but concrete structure, design, anufacturability etc. with very big difference was arranged originally, this charging air inlet component design is reasonable, manufacturing process is simple, manufacturing efficiency is high, and those skilled in the art are easy to manufacturing.This tire inflatabling nozzle assembly can obtain good sealing property, and is easy to use, and the life-span of rubber improves greatly.Compared following advantage with former tire inflatabling nozzle assembly: structure decrease, it is more reasonable to design, and processing technology is simple, low cost of manufacture.Materials consumption reduces, and it is easy that the user changes rubber, and than original laborsaving about 65%, the rubber replacement cycle is long, is easy to clear up the interior foul of charging air inlet during inflation.
Below with reference to accompanying drawing the utility model is described in further detail.
Fig. 1 is the tire inflatabling nozzle assembly schematic representation.
Fig. 2 is the utility model valve schematic representation.
Fig. 3 is the utility model inflation seat schematic representation.
With reference to accompanying drawing, the tire inflatabling nozzle assembly main structure has inflation seat (3), and the inflation seat is assemblied on the tire (7), adopts locking nut (5) and pad (6) to be locked on the tire.Inflation seat (3) the other end is equipped with charging air inlet (1), is set with caulking gum sleeve pipe (4) on the charging air inlet, and the caulking gum sleeve pipe is having conical boss with (3) sealing surface assembling place of inflation seat, and inflation seat sealing surface has the female cone degree.Charging air inlet (1) air outlet hole is two-sided through hole, just with the inflation with the cleaning charging air inlet in foul.Charging air inlet and nut (2) mating face is the cylinder flanged surface, and nut (2) is assemblied in inflation seat (3) end with charging air inlet, and adopts fastening screw nut and tight, in case the loosening gas leakage of charging air inlet.
Claims (1)
- A kind of tire inflatabling nozzle assembly with charging air inlet, nut, inflation seat, caulking gum sleeve pipe, locking nut, pad, fastening screw nut, it is characterized in that the charging air inlet sealing surface adopts cylindrical structure, flanged surface is processed in the outer end, charging air inlet center hole outer end flare taper hole, the bottom is a cylindrical hole, air outlet hole is two-sided through hole, inflation seat head endoporus has step, be processed with the endoporus of conicity, make sealing surface, the caulking gum sleeve pipe is having taper shape or arc cam with inflation seat sealing part, and the bottom is a tubular shape, is used to seal air outlet hole.
