Its four, various vehicles can in use be stabbed because of foreign object and be caused inner tube of a tyre explosion situation, so prior art real worry that causes anxiety on safety.

Though also have manufacturer to look on the bright side of things at present to send out and exempt from inner tube of a tyre inflatable tire, but because the charging valve apparatus structure complexity (its inside contains valve, air tube, valve member) of inflatable tire, so the installation group is upright very difficult, not only can greatly improve the manufacturing cost of product, and also be a test dealer's manufacturing technology; On the other hand, the prior art air-valve device needs to pass outwards through the set through hole of wheel rim by inner plenum, and for small-sized small tyre, size is long, the charging valve device of assembling trouble can can't be organized upright installing because of wheel rim is too small, and cause the problem that too projective structure is outside or inflation is difficult when group is stood operation.

Shortcoming for above-mentioned conventional small tire construction, improvement trend is demand with the durability that improves the PU tire all at present, though so improvement has its effect, but the utility model is not as limit, and more deep design has more the improvement of intention and effect, in the hope of promoting the practicality of conventional small tire construction significantly; Go through repeatedly research and develop, study after, create a kind of wheel rim structure-improved that is applicable to the small tyre gas filled device finally.

Main purpose of the present utility model be to provide a kind of can be on small tyre the wheel rim structure-improved of the upright charging valve device of simple and easy installation group, the utility model is made in rim structure and is established a small-sized independent air chamber, pass to the air chamber of tire in this independent air chamber, and charging valve is installed in (both sides of rim structure) between this independent air chamber and the external world, oversimplify and the installation group that makes charging valve is upright, no longer be subject to the labyrinth of charging valve.

Secondary objective of the present utility model is to provide a kind of durable small tyre wheel rim structure-improved, the utility model is by tire match wheel coil structures, and system is established by outward towards independent air chamber, the through hole of tire air chamber on rim structure, so can use and exempt from inner tube of a tyre formula tire, produce preferable stability and preferable conjugation.

An order more of the present utility model is to provide a kind of small tyre wheel rim structure-improved with adjustable features, action superperformance, the utility model is to cooperate the charging valve inflation by independent air chamber, through hole, the interior air chamber pressure of tire can be adjusted according to need, and have preferable action elasticity.

The purpose of this utility model is achieved in that a kind of wheel rim structure-improved, it is characterized in that including: a tire is the annular tire of without inner tube type; One wheel rim, be to be positioned within this tire, and be formed with air chamber between wheel rim and this tire, and to offering an independent air chamber in wheel rim inside by air chamber, and this independent air chamber offers a through hole that outwards leads to, and offers the through hole that leads to air chamber between wheel rim and this tire in this independent air chamber one side in addition; One charging valve includes the valve member of a valve, an air tube and tool spring, and be the group be located at this wheel rim in accessibke porosity.This tire can be tubeless tire.
