Abstract

The utility model provides a tire air valve and a fixing device, which are mainly composed of an air valve, a leak proof rubber washer, a locking wheel ring, a nut and an air valve cap. The locking washer and the leak proof rubber washer are all tightly attached to the upper side and the lower side of a wheel frame by the fastening nut to cause the air valve to be steadily fixed on the wheel frame. The phenomenon the air valve swings can not be generated, and air in a tire can not leak out. The utility model can reach the optimal leak proof and fixing effect.

Description

Tire valve and anchor fitting

The utility model relates to being connected of a kind of tyre tube valve and tire or wheel rim.

The wheel frame of wheel use at present most adopts aluminum alloy system, this kind wheel frame style is done airflow design more, make wheel rim frame outside tool circular arc protrude edge, at wheel rubber base wind being set on the frame chews the bottom of (as Fig. 1,2) valve 10 and establishes permanent seat 11, position bulge loop 12 is set in permanent seat 11 tops, valve 10 can be positioned on the wheel frame A, it is by outwards pullling in the wheel frame A that this kind rubber base wind is chewed, fix with rubber permanent seat 11 and wheel frame A packing mode, fixedly after wind is chewed still and can be rocked, more dangerous in the use, phenomenon such as may leak gas, get loose.

The purpose of this utility model is that a kind of tire valve and anchor fitting will be provided, but its secure has best leak preventing effect on the wheel frame.

The utility model is achieved in that the bottom of valve establishes permanent seat, the outer wall upper and lower side of valve respectively is provided with outside thread, the leakproof rubber grommet is set in the permanent seat top of valve, the upper and lower of leakproof rubber grommet all convexes with bulge loop, valve and leakproof rubber grommet are located on the wheel frame, retaining washer is set on the valve, and nut is located at the top and the solid external thread part below valve of spiral shell of retaining washer, and the valve cap is located at the external thread part of valve upper end.

The utility model screws nut makes retaining washer and leakproof rubber grommet all closely be attached to wheel frame upper and lower, makes the valve secure on the wheel frame, can not produce shaking phenomenon, and the gas in the tire can not leak outside, and can reach best leakproof and immobilization efficiencies.

The concrete structure of utility model is provided by following examples and accompanying drawing thereof.

Fig. 1 is that traditional rubber base wind is chewed the use scheme drawing.

Fig. 2 is that traditional rubber base wind is chewed and analysed and observe and the stressed scheme drawing that rocks.

Fig. 3 is an axonometric exploded view of the present utility model.

Fig. 4 is an assembled sectional view of the present utility model.

Fig. 5 is another embodiment axonometric exploded view of the utility model.

Fig. 6 is another embodiment assembled sectional view of the utility model.

With reference to Fig. 3,4, tire valve and anchor fitting are by a valve 20, one leakproof rubber grommet 21, one retaining washer 22, an one scalariform nut 23 and a valve cap 24 are formed, wherein valve 20 is vertical, a discoid permanent seat 200 is established in its bottom, on valve 20 outer walls, the bottom respectively is provided with outside thread 201,202, leakproof rubber grommet 21 is set in permanent seat 200 tops of valve 20, the upper and lower of leakproof rubber grommet 21 all convexes with a bulge loop 210, valve 20 and leakproof rubber grommet 21 are located on the wheel frame, again a retaining washer 22 is set on the valve 20, one scalariform nut 23 is provided in a side of retaining washer 22 tops, and 202 ones of solid outside threads in valve 20 lower ends of spiral shell, screw scalariform nut 23, make retaining washer 22 and leakproof rubber grommet 21 all closely be attached to the upper and lower of wheel frame, and valve cap 24 lid is located at 201 ones of the outside threads of valve 20 upper ends, can finish assembling.

Said structure nut 23 is scalariform, can be for the cap key locking, 23 lockings of valve 20 mat scalariform nuts, make valve 20 secure at the wheel frame, can not produce shaking phenomenon, mat scalariform nut 23 tight locks can force leakproof rubber grommet 21 and retaining washer 22 to be close to wheel frame upper and lower, and the interior gas of tire can not leaked outside.

With reference to Fig. 5,6, be another embodiment of the utility model, by valve 30, leakproof rubber grommet 31, retaining washer 32, general hexagonal nut 33 and valve cap 34 are formed, valve 30 L-shaped bendings wherein, discoid permanent seat 300 is established in valve 30 bottoms, on valve 30 outer walls, outside thread 301 is respectively established in the bottom, 302, leakproof rubber grommet 30 is set in permanent seat 300 tops of valve 30, the upper and lower of leakproof rubber grommet 31 all convexes with a bulge loop 310, valve 30 and leakproof rubber grommet 31 are located on the wheel frame, again retaining washer 32 is set on the valve 30, general hexagonal nut 33 is located at retaining washer 32 tops, and 302 ones of solid outside threads in valve 30 lower ends of spiral shell, screwing nut 33 makes retaining washer 32 and leakproof rubber grommet 31 all closely be attached to the upper and lower of wheel frame, and valve cap 34 lid is located at 301 ones of the outside threads of valve 30 upper ends, this structure screws nut 33 backs and aforesaid scheme has equal effect.
