Abstract
The utility model provides a rim valve hole structure. A valve hole is a round through hole formed in a rim, and inner and outer annular concave bosses are arranged on the inner and outer edges of the through hole. The valve hole of the steel rim is designed to be in a boss and round through hole structure, so that the installation reliability of a tire valve is improved, the service life of the tire valve is prolonged, and cars can travel safely.
Description
Technical field
The utility model relates to the light bus technical field, is specifically related to a kind of wheel rim valve port structure.
Background technology
The wheel valve port of tubeless tires is installed on the wheel rim, wheel is inflated by tire tube valve, the tire tube valve sealing requirements is higher, steel inner tube free wheel rim valve port is through hole, and the corner in hole does not process, the tire tube valve of buckle-type and wheel rim valve port cooperation place are rubber structure, and the assembling back causes the risk of tire flat because the vibration of car load causes damage to tire tube valve easily.
The utility model content
In order to address the above problem, the purpose of this utility model provides a kind of improved wheel rim valve port structure.
In order to realize the purpose of this utility model, the utility model provides following concrete technical scheme:
A kind of wheel rim valve port structure, for being positioned at the manhole on the wheel rim, the outer edge of this through hole is provided with the inside-and-outside ring boss of depression.
Preferably, the diameter of described annular boss is 15mm, and the diameter of described through hole is 11.5mm, and the degree of depth of described inside-and-outside ring boss depression is 0.5mm.
The beneficial effects of the utility model are as follows:
The valve port of the utility model steel wheel rim has improved installation reliability and the service life of tire tube valve by the structure design of boss and manhole, has guaranteed the safety traffic of automobile.
Description of drawings
Fig. 1 is the utility model wheel rim integral structure figure;
Fig. 2 is the utility model wheel rim valve port outside local structure figure;
Fig. 3 is outside local structure figure in the utility model wheel rim valve port;
Fig. 4 is the installation sketch of tire tube valve on wheel rim;
Reference numeral is as follows among the figure:
Wheel rim 1, wheel rim valve port 2, tire tube valve 3, annular boss 21,22.
The specific embodiment
Introduce the utility model in detail below in conjunction with accompanying drawing and the specific embodiment thereof.
Shown in Fig. 1～3, a kind of wheel rim valve port structure, for being positioned at the manhole 2 on the wheel rim 1, the outer edge of this through hole 2 is provided with the inside-and- outside ring boss 21,22 of depression.
One concrete scheme of present embodiment is as follows, and described inside-and- outside ring boss 21,22 diameter are 15mm, and the diameter of described through hole 2 is 11.5mm, and the degree of depth of described inside-and- outside ring boss 21,22 depressions are 0.5mm.
As shown in Figure 4, tire tube valve 3 is installed on the valve port 2 of wheel rim, the wheel of buying car in installments charges and discharge gas and uses, because the tire tube valve periphery is generally elastomeric material and makes, valve port 2 makes firm being installed on the wheel rim of tire tube valve by boss and the circular structure design that passes through in the present embodiment, has also reduced the wearing and tearing of tire tube valve simultaneously, and then installation reliability and the service life of having improved tire tube valve, guaranteed the safety traffic of automobile.
The above only is preferred implementation of the present utility model, it is to be noted, these embodiment only are used for explanation the utility model and are not used in restriction scope of the present utility model, and, after having read content of the present utility model, the relevant technical staff in the field can make various changes or modification to the utility model, and these equivalent form of values fall into the application's appended claims institute restricted portion equally.
