Description
Technical field
The utility model relates to the vehicle body fittings technical field, refer in particular to a kind of firm, disassembling, assembling and replacing inner tube of a tyre simple in structure convenient, prevent the non-inflatable tyre that misplaces.
Background technology
Chinese patent ZL 01214861.X has announced " non-inflatable tyre ", and its purpose is that real in-core tire is packed in the cover tire, is convenient to industry manufacturing, and reduces the manufacturing cost of cover tire.Its structure comprises cover tire and real in-core tire, and cover tire only is made of carcass.Adopt the weak point of this structure to be: the non-inflatable tyre that this inner tube of a tyre of being filled by cover tire and elastomeric material constitutes can't the heavier tire of load, and inconsistent phenomenon also easily takes place between the Tire ﹠ Tube of this structure, brings inconvenience to use.
And the design of traditional non-inflatable tyre, constitute by cover tire and real in-core tire, include the nylon netting twine of carcass, reinforced rib and inwall etc., after adopting this conventional confguration, owing to inlaying reinforced rib in the cover tire edge, therefore be not easy to real in-core tire is filled in the cover tire, very inconvenience can't realize industrialization during the disassembling, assembling and replacing inner tube of a tyre.
Summary of the invention
The purpose of this utility model be exactly provide at the deficiencies in the prior art part a kind of simple in structure firm, the disassembling, assembling and replacing inner tube of a tyre convenient, prevent the non-inflatable tyre that misplaces.
For achieving the above object, the utility model comprises wheel hub and the suit solid inner tube on it, be coated on the cover tire on the solid inner tube outside, have circular trough on the inner tube of a tyre two side (face), the cover tire fin of engaging and its form fit in this circular groove, inner tube of a tyre outside face is provided with one or more recess, corresponding cover tire inner face be provided with corresponding can with the protruding position of recess fit, location.
The inner tube of a tyre is by the two side end face vertical with wheel shaft, and the circular groove that has on the end face is formed.
Inner tube of a tyre circular groove bottom is extended another perpendicular circular groove and is nested with the projection that extension is done in cover tire nose end.
The toroid position of inner tube of a tyre outside face outermost end has one or more recess.
The both sides at the toroid position of inner tube of a tyre outside face outermost end are arranged with several recess respectively.
The both sides at the toroid position of inner tube of a tyre outside face outermost end are respectively equipped with staggered several recess.
The recess that inner tube of a tyre outside face is provided with is hemispherical round pool.
The cover tire fin is provided with perpendicular straight gear.
The protruding position of inner surface of cover tyre is that column and end are the projectioies of taper.
Inner tube of a tyre inside face is provided with one or more and the protruding position of the wheel hub recess of fit, location mutually.
After adopting said structure, adopt on perambulator or wheelchair or the trolley for hospital use exempt from inflation tyre after, have long-term use and need not inflate, characteristics such as durable in use, in addition, after it has been stabbed by sharp-pointed hard thing, because its inner tube of a tyre is a solid material, therefore, little to its Safety Effect; Because cover tire is directly to be fastened in the circular groove of the inner tube of a tyre, can directly the circular groove of cover tire from the inner tube of a tyre be taken out during dismounting, very convenient; And the concave, convex position that cooperatively interacts between inside and outside tire and the wheel hub can prevent dislocation effectively.Therefore, the utlity model has firm, easy accessibility simple in structure, safe, can prevent dislocation, need not characteristics such as inflation.
Description of drawings
Fig. 1 is the spatial structure decomposing schematic representation of a kind of embodiment of the utility model;
Fig. 2 is the tire cross section part sectional view of a kind of embodiment of the utility model.
The specific embodiment
Shown in accompanying drawing 1～2: the utility model includes: wheel hub 1 and the suit solid inner tube 2 on it, be coated on the cover tire 3 on the solid inner tube outside, have circular trough 21 on the inner tube of a tyre 2 two sides (face), the cover tire fin 31 of engaging and its form fit in this circular groove 21, the inner tube of a tyre 2 outside faces are provided with one or more recess 22, corresponding cover tire 3 inner faces be provided with corresponding can with the protruding position 32 of recess 22 fits, location.The inner tube of a tyre 2 is by the two side end face vertical with wheel shaft, and the circular groove 21 that has on the end face is formed.Inner tube of a tyre circular groove 21 bottoms are extended another perpendicular circular groove and are nested with the projection 211 that extension is done in cover tire nose end.The toroid position of the inner tube of a tyre 2 outside face outermost end has one or more recess 22.The both sides at the toroid position of the inner tube of a tyre 2 outside face outermost end are arranged with several recess 22 respectively.The both sides at the toroid position of the inner tube of a tyre 2 outside face outermost end are respectively equipped with staggered several recess 22.The recess 22 that the inner tube of a tyre 2 outside faces are provided with is hemispherical round pools.Cover tire fin 31 is provided with perpendicular straight gear 311.The protruding position 32 of cover tire 3 inside faces is that column and end are the projectioies of taper.The inner tube of a tyre 2 inside faces are provided with one or more and the protruding position of wheel hub 11 recess 23 of fit, location mutually.
When using the utility model, the embodiment of a perambulator tire that goes out as illustrated in fig. 1 and 2, when the wheel hub 1 of perambulator is driven and is rotated, because the inner tube of a tyre 2 is entrenched in the wheel hub 1, and cover tire 3 embeds, is locked in the circular groove 21 of the inner tube of a tyre 2 both sides, like this, wheel hub 1 and inside and outside tire 2,3 become one, and together roll on the ground; When sharp-pointed hard thing is exposed cover tire 3 and is stabbed the inner tube of a tyre 2, because the inner tube of a tyre 2 is that solid soft plastic material is made, therefore, the safety of perambulator is not had too much influence yet, children can relievedly continue to take, and are more safe and reliable, durable in use than traditional inflatable inner tube.Also very convenient when needs are changed the tire inner tube of a tyre 2, only need cover tire 3 is directly taken out from the circular groove 21 of the inner tube of a tyre 2, again the inner tube of a tyre 2 is taken out to change from nave boss 1 and get final product.And the concave, convex position that cooperatively interacts of moulding can be shaped to various rules or the erose concave, convex position that cooperatively interacts as required between the inner tube of a tyre 2, cover tire 3 and the wheel hub 1, thereby more effectively prevents dislocation, makes its structure more firm.Therefore, the utlity model has firm, easy accessibility simple in structure, safe, can prevent dislocation, need not characteristics such as inflation.
