Description

Available tubeless tires inner tube of a tyre wheel rim arranged

The utility model relates to a kind of inner tube of a tyre wheel rim that has, and what refer to a kind of available tubeless tires especially has an inner tube of a tyre wheel rim.

Bicycle and locomotive, in China is the vehicle that use in a large number and make, bicycle and locomotive have had appreciiable kind and function at present, to meet the requirement of people for row, wherein many effort have been done for the structure of wheel rim and tire, and produced tubeless tire, to improve user's practicality and safety; Announce [tool width of cloth silk is exempted from the hermetically-sealed construction of inner tube of a tyre wheel] No. 354530 as Taiwan, mainly width of cloth wire connection hole is sealed with a stickiness adhesive tape, and be aided with rubber boundary belt (promptly being commonly called as lining band), make the unlikely leakage of air pressure in the tubeless tires, but this structure does not contact with tire, if it is bad that the stickiness adhesive tape is fitted, the hidden danger of pressure release is arranged promptly; And for example [tire construction of inner tube free] announced in Taiwan No. 319180, mainly the tubeless tires structure by particular design combines with wheel rim, guarantee its air-tightness by lug and colloid ring, the out of roundness of wheel rim and the structure of tire all can influence its air-tightness, depend merely on contacting of lug and colloid ring small size, can't guarantee the driving fit of its contact, and need the tubeless tires of collocation special construction, and do not have a ubiquity, make the customer be difficult to follow; Announce No. 239101 for another Taiwan [sealing arrangement that is used for the radially width of cloth bar wheel of inner tube free], mainly in the wheel rim outer rim ring establish a dovetail type groove with rubber tape is filled in guarantee air-tightness with the installing tubeless tires, but its shortcoming is identical with last case, do not have a ubiquity, be that wheel rim needs particular design to produce with special, can't be used on the existing product that uses.

Tubeless tire is installed having on the spoke wire wheel coil structures of commonly using, but can't reach anti-effect of losing heart, see also shown in Figure 1, its single-piece structure includes the wheel rim 20 of a circle frame shape and the cover tire 21 and the inner tube of a tyre 22 of a ring-type, wherein the lateral border of wheel rim 20 is a groove 201 shapes, for inserting the inner tube of a tyre 22 and cover tire 21, be provided with several perforation 202 to insert spoke steel wire 23 at these groove 201 root edges, be provided with an air nozzle hole 203 to insert valve 221 at appropriate location, 23 on the inner tube of a tyre 22 and spoke steel wire are provided with a lining band 24, make direct contact to avoid taking turns steel wire 23 with the inner tube of a tyre 22, making integral body is known wheel rim 20 structures (please cooperate shown in Figure 2) with the inner tube of a tyre, yet it has the design of the inner tube of a tyre, productive costs is higher, and causes the waste of resource and the puzzlement in the recycling easily; Wherein, if directly change tire into tubeless tire, then owing to fit closely between tire and the wheel rim, gas can be from leaking therebetween, and can't normally use.

The purpose of this utility model provides a kind of existing wheel rim that is equiped with inner tube tyre of reequiping, make it become the wheel rim that to install tubeless tires, and installation process is rapid easily, and load onto tubeless tire and make the single-piece structure can definitely prevent leaking outside of gas, have the practicality of industry and the benefit of cost.

For achieving the above object, solution of the present utility model is: available tubeless tires inner tube of a tyre wheel rim arranged, comprise the wheel rim of a circle frame shape and the tire of a ring-type, the outside circle of wheel rim is a groove shape, wherein establish a shape and the consistent envelope body of wheel rim groove between the groove of tire and wheel rim, it fits tightly in the groove of wheel rim.

Above-mentioned available tubeless tires inner tube of a tyre wheel rim arranged, wherein these envelope body both sides are connected with to wheel rim both sides outer rim.

After adopting such scheme, of the present utility model have a following advantage:

1, uses soft rubber to make the envelope body and have excellent sealing ability, make the gas in the tubeless tire can not produce the phenomenon that leaks outside, have excellent leak preventing effect.

2, can reequip with existing wheel rim, install easily rapidly, not need speciality tool.

3, when tire is pierced, it is disappointing that tire is difficult for moment, can improve safety.

4, the wheel rim after the repacking also can be installed the inner tube of a tyre according to special demand, thus two kinds all be suitable for, make the multi-functional purposes of its tool.

Below in conjunction with drawings and Examples the utility model is further described.

Fig. 1 is a three-dimensional exploded view of commonly using product;

Fig. 2 is a cross-sectional schematic of commonly using product;

Fig. 3 is a three-dimensional exploded view of the present utility model;

Fig. 4 is a cutaway view of the present utility model.

See also shown in Figure 3, a kind of inner tube of a tyre wheel rim that has of available tubeless tires includes the wheel rim 10 of a circle frame shape and the tire 11 of a ring-type, wherein the lateral border of wheel rim 10 is a groove shape, for putting into tire 11, these groove 101 root edges are provided with several perforation 102, to insert spoke steel wire 12, and be provided with an air nozzle hole 103 at appropriate location, with a ccontaining valve 132, it should be noted that, be provided with the envelope body 13 of a circle shape at 101 of the grooves of tire 11 and wheel rim 10, the both sides of this envelope body 13 are connected with respectively to the both sides outer rim of wheel rim 10 grooves 101, and it is fitted tightly in the groove 101 of wheel rim 10, and this tubeless tires 11 combine with wheel rim 10 assembling after, still can see the envelope body 13 that is convexly equipped with in wheel rim 10 both sides outer rims, large tracts of land is fitted, guarantee air-tightness, the direct pressurising of gas is in tire 11, make it be a saturation conditions, wherein valve 132 is arranged in air nozzle hole 103, one end direct contact envelope body 13, and the one end can fit tightly on envelope body 13 when the compressing that is subjected to gas, and tire 11 has large tracts of land applying closely with envelope body 13, can reach the effect of airtight leakproof.

The structure of this wheel rim 10 can be used in existing use spoke steel wire 23 and have on the locomotive or bicycle of the inner tube of a tyre 22, when this wheel rim 10 uses tubeless tire 11, because of tubeless tire 11 structures stronger, just in case tire 11 is punctured when losing heart because of carelessness, still have cooresponding strength support (seeing also shown in Figure 4), therefore have cooresponding practicality and effect.

When tire was pierced, it is disappointing that tire is difficult for moment, can improve safety.
