Abstract
The utility model discloses a pressing tight type air valve with no inner tube, which comprises a valve body, a valve core, a sealing cap, a sealing gasket and a tight nut, wherein the main part of the valve body is a hollow tube, and the valve core is arranged in inner cavity of the upper part of the hollow tube. The upper end of the hollow tube is provided with an external screw for being spirally connected with the sealing cap, and the lower part of the hollow tube is provided with an external screw matched with the tight nut. The lowest end of the hollow tube is integrally provided with an end pinch plate which is arranged in a radial direction. The utility model is characterized in that the plane surface of the upper end of the end pinch plate is provided with an annular raised line, and the sealing gasket is at least provided with a flat ring body matched with the upper end surface of the end pinch plate. The utility model has the advantages of high sealing pressure, stable and reliable working and convenient installation, which is suitable for tyres with no inner tube of various vehicles such as motorcycles, cars, light motor lorries, motor lorries, passenger cars, etc.
Description
Technical field
The utility model relates to a kind of inner tube free clamp-in valve, and it is applicable to the tubeless tires of various vehicles.
Background technology
Tubeless tires has been widely used in various vehicles such as motor bike, car, light truck, autotruck and passenger vehicle.At present, the structure of the used tire tube valve of tubeless tires is: comprise mouth body, valve inside, seal cap, seal ring and clamp nut; The base portion of mouth body is a hollow tube, in the inner chamber on hollow tube top valve inside is installed; The upper end of hollow tube is provided with the outside thread of the seal cap that is used to be spirally connected; Hollow tube bottom, also being that end end of the mouth body wheel rim inboard that is snapped in tire is one-body molded has an end buckle that radially is provided with: the last transverse plane of end buckle is provided with the groove around hollow tube, and seal ring is housed in the groove; The hollow tube bottom is provided with outside thread.During use, hollow tube passes from the valve port of wheel rim, and the cover Upper gasket screws on the nut adaptive with the outside thread of hollow tube bottom, and the seal ring that then is installed in the end buckle upper groove forms sealing between end buckle and wheel rim inwall.The defective of this structure is: need guarantee in the installation process that 1, seal ring embeds in the groove, and seal ring positioning easily, thereby installation is very not convenient; 2, for reaching sealing effectiveness, must leave the gap between end buckle and the wheel rim inwall, otherwise seal ring will not have due sealing function, thereby when fastening nut, can not overtorquing, after will causing tire tube valve to tighten the sealing assembling like this with wheel rim, there are problems such as sealing load is low, tire tube valve is easily loosening with the contact site of wheel rim, oxidation, corrosion, this class problem occurs especially easily on summer, winter and rough road surface, and cause tire flat, thereby bring great potential safety hazard.If in the self-propelled vehicle generation tire flat phenomenon of running on expressway, even the roll-over accident of car crash can take place.Certainly, the seal ring of the structure that is provided with a circle bulge loop on a flat ring is arranged also,, but still have above-mentioned problem though its effect has improvement slightly.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of sealing load height, stable and reliable operation inner tube free clamp-in valve at above-mentioned prior art present situation.
The utility model solves the problems of the technologies described above the technical scheme of being taked: this inner tube free clamp-in valve comprises mouth body, valve inside, seal cap, packing seal and clamp nut; The base portion of mouth body is a hollow tube, and described valve inside is installed in the inner chamber on hollow tube top, and the upper end of hollow tube is provided with the outside thread of the described seal cap that is used to be spirally connected, and the bottom then is provided with the outside thread adaptive with described clamp nut; Hollow tube one-body molded bottom has the end buckle that radially is provided with, and it is characterized in that the last transverse plane of described end buckle is provided with ring rib, and described packing seal has and the adaptive flat ring body in described end buckle upper surface at least.
The cross section semicircular in shape of described raised line or square or triangle are good with semicircle wherein, and the binding face possible because of itself and packing seal is bigger, helps forming good sealing.
Described packing seal is flattened cylindrical body shape, and its center has and can hold the hole that described hollow tube passes.
The height of described raised line is 0.3～1.5mm, raised line is too little, when then sealing the distortion of packing seal few, may be difficult to form good sealing, too big when then packing seal is compacted with the applying of raised line side and possible relatively poor with the applying of described end buckle remainder, also will influence the leak free effect.
Compared with prior art, the utility model adopts the mode and the packing seal sealing of establishing raised line on the end buckle can bring following beneficial effect: even 1 clamp nut is twisted tightlyer, hold the situation that also can accompany packing seal all the time between buckle and the tyre rim inwall and be unlikely to occur both direct contacts, add the extruding of raised line, thereby can guarantee sealing and obviously improve sealing load packing seal; 2, because of the area of packing seal obviously greater than the area of raised line, even thereby in installation or use, the position of packing seal is mobile to some extent, still can form good sealing between packing seal and the raised line, so its work is highly stable reliable, improved the driving safety of vehicle; 3, installation is more convenient,

Specific embodiment
Embodiment describes in further detail the utility model below in conjunction with accompanying drawing.
Embodiment one
As Fig. 1～shown in Figure 2, be a preferred embodiment of the present utility model.As shown in Figure 1, the described inner tube free clamp-in valve of present embodiment comprises mouth body 1, valve inside (not shown), seal cap 2, packing seal 3, pad 4 and clamp nut 5; With reference to Fig. 2, the base portion of mouth body 1 is a hollow tube 101, in the inner chamber on hollow tube 101 tops valve inside is installed, and the upper end of hollow tube 101 is provided with the outside thread of the seal cap 2 that is used to be spirally connected, and the bottom then is provided with the outside thread adaptive with clamp nut 5; Hollow tube 101 one-body molded bottom has the round nose buckle 102 that radially is provided with, 102 of buckles of next-door neighbour end form with tyre rim 6 on the adaptive cylindrical step 103 in valve port aperture, this step is the adaptive outside thread of above-mentioned and clamp nut 5 more than 103.To be provided with the cross section be semi-round ring rib 104 to the last transverse plane of end buckle 102, and the radius of this semicircle is 1mm, and packing seal 3 is flattened cylindrical body shape, and its center has the hole that the cylindrical step 103 that just can hold hollow tube 101 bottoms passes.
