The utility model inner tube of a tyre is made up of the identical mole 1 of four block-shaped structures, be provided with chock 2 between piece and the piece, the width of the inner tube of a tyre is slightly less than the width of steel basin and the width 10～30mm of cover tire, and the thickness of the inner tube of a tyre equals that cover tire is thick and deduct (the axis of the piston thick+fixedly the space of thickness of slab+10～20mm).

The inner tube of a tyre of external diameter in the thickness width will be determined, divide and make four of equirotal ABCD, see Fig. 1, in order to put into cover tire, outer length that ABCD is four and interior length should be less than the 5～10mm that branched away originally, the space of 10～20mm is arranged between AB, BC, CD, the DA like this, and fill with chock 2 after ABCD puts into cover tire fully in these spaces.Shade partly is a chock 2, the outer rim length of chock is identical with inner edge length, the thickness width is the same with mole, it is fixed that concrete size is come by the size in space, making does not have space degree of being between the mole, just can enter with hammering possibly when putting last piece chock, so last piece chock must be done a pitting in inner edge one side, withstand this hole with screw base and so on when taking out, come out with beating chock side.

For the inner tube of a tyre is all put into cover tire, must cut three breaches (as Fig. 2 in the one side of cover tire, cut four in case of necessity) at A, B, C cuts at the place, A should be a bit larger tham mole length 10～20mm to C and a to the distance of c, A is to a, B is to b, C gets final product than the big 10～20mm of mole thickness to c, when last piece mole is put into cover tire, the AB and the BC piece of cover tire can be turned up and can put into, fill chock again, with two of the offset plates of shape such as Fig. 5, inside and outside (these two offset plate shapes sizes that breach is clamped, thick about 10mm, colloid and cover tire the same, also available waste and old cover tire is done) fix with screw, what are arranged to hole, want the cooresponding spiral nail of number, the clamping plate on spiral nail both sides are made of irony, the length of offset plate is greater than the distance 70～100mm of the A that severs to C, A is to a, B is to b, distance 30～50mm of c to C, first-class nut and tighten all nuts after, be inserted in steel bushing, there is spiral nail that mole is fixed on the steel basin, and install breather pipe and inflate at last, the used air pressure of Long service life inner tyre is identical with rubber inner tube, and this face of when wheel is installed blob of viscose being clamped turns to the inside, just is not easy to find out, should extract this auxiliary splint earlier when getting the inner tube of a tyre, be undertaken by the opposite sense of adorning the inner tube of a tyre.

The fixing of mole is fixed on mole on the steel basin exactly; mole is not at will moved; help the protection of cover tire and travelling of vehicle; its way is: the screw hole of 6 12mm is bored on the inner edge surface both sides of every mole; 3 on every limit; corresponding perforations is bored at corresponding position in steel basin both sides of the edge simultaneously, by bolt mole is fixed on the steel basin.

The outer rim of steel basin (with the contact surface of mole) must be smooth, the bad use Long service life inner tyre of irregular steel basin, but the irregular steel basin of a lot of outer rims is arranged at present in use and for sale, for unnecessary waste, when the inner edge of design mole, under the smooth prerequisite of the outer rim that keeps mole, adjust the degree of dip of the inner edge surface of mole according to the degree of dip of steel pelvic surface of sacrum, principle is that mole inner edge and steel pelvic surface of sacrum coincide, and makes the mole outer rim smooth again.The production of new steel basin can make it smooth, to be fit to the requirement of Long service life inner tyre.

The old cover tire that has is as long as after the axis of the piston is upheld, the axis of the piston surface is complete and the cover tire inwall is identical, just can use, also can design the axis of the piston surface configuration according to the cover tire internal face, the making of new cover tire designs the inwall of cover tire according to the axis of the piston surface, cut the both sides of three breaches and bore several apertures, as Fig. 2 so that put fix screw.

The making principle of this inner tube of a tyre is Boyle, Robert one boyle's law, the pressure that is the gas of certain mass changes along with the variation of volume, the simple sample of this inner tube of a tyre is the piston of injector for medical purpose and diesel engine, the interior injector for medical purpose that one section air is arranged of storing, seal nipple extrusion piston axle and can feel flexible, the piston that this inner tube of a tyre is used can not be simple piston, must copy the piston of diesel engine to make piston for durable utterly with anti-gas-leak, its structural behavior is fully identical with the piston of diesel engine.

The making of mole should be carried out in conjunction with the pipeline manufacture craft, could realize the venting channels in the piece, mole inner structure such as Fig. 4,7.Wherein the thickness of bottom and sidewall under the situation that the thickness of empty barrel all can not break, designs the thinnest limit when bearing maximum pressure.Because vehicle will bear a heavy burden, make the steel of the material application making jack of mole, piston and do.

Fig. 4 is the cutaway view of mole, a general mole longitudinal arrangement one emptying tube 6, also can two row, inner structure as Fig. 4, considering when bearing maximum pressure that empty barrel can not break and the width length of mole designs the size of empty tube and the distance between the empty tube, general empty barrel Min. is 20mm, principle is that the big more elasticity of empty tube is good more, and smooth Never-rusty is wanted on empty tube 6 inwalls and piston 5 surfaces.Empty tube bottom communicates, and as Fig. 4, forms an air cavity 8, the empty tube degree of depth equals the piston barrel portion, and (20～60mm) add upper piston square part, and (25～35mm), air cavity 8 communicates with air flue 10, and air flue 10 and tracheae 14 join, connect the air flue of another piece again, the air cavity of logical another piece.

The shape of the axis of the piston 3 such as Fig. 4, the surface of the axis of the piston is after extension, must fully contact with the cover tire inwall, corner angle can not be arranged, in order to avoid hurt cover tire in motion, two the axis of the piston spacings are 5～10mm when not upholding, and make the axis of the piston grazing mutually when upholding or shrink, but can not be from far, the axis of the piston 3 is necessary for solid with piston 5 and links to each other, can not do combination, bear very big pressure again because of it is both movable, the axis of the piston thickness is 20～60mm, if dried mushroom shape, each place of thickness is all inequality, principle be save under the situation of material, can bear maximum pressure again.Do not having under the gas filed situation, the axis of the piston surface is from cover tire inwall 10～30mm, if when not having cover tire to encase, after piston was upheld, the axis of the piston should stretch out cover tire inwall 10～25mm, and cover tire ability is by inflation like this.

Piston 5 is divided into two parts, and one is cylinder, and one is square, and both are connected as one.Square partly adds barrel portion and equals the dark fixedly thickness of slab that adds of empty tube, and the length of square part is the flexible length of piston, is generally 25～35mm.Square has two functions, prevents that piston from rotating to the left and right and because air pressure is too high, and piston is released mole sometimes even fly out and hurt sb.'s feelings, and the diagonal line of square bottom surface equals the long 20～60mm of cylinder bottom surface circle diameter cylinder.Diameter is decided according to the internal diameter of empty tube, three piston rings and two water shutoff circles are installed on it, piston ring plays the effect of envelope gas, the water shutoff circle is that anti-sealing and dust enter in the empty tube, the manufacture craft of cylinder part connects the piston of diesel engine and makes, its functional performance form is identical with the piston of diesel engine, also can so say, the piston of diesel engine is used.A cylinder and an empty tube inwall are answered Never-rusty, and the used material of piston ring and water shutoff circle is identical with diesel engine, is coated with the last layer lubricating oil at empty tube inwall and barrel portion during use, and effect has 2 points, and anti-gas-leak and increase are lubricated.

The adapter plate 7 of piston is the irony plate of a shape such as bridge arch, thick 8～10mm; The size width is the same with the outer edge surface of mole, with the cooresponding position of empty tube, bore the square hole of a diagonal line greater than the diagonal line 1～2mm of the square of piston, by this square hole, piston is fixed in the empty tube, mustn't be released outside the empty tube by air pressure by piston, mustn't rotate to the left and right by piston simultaneously,, adapter plate is divided do two if empty tube is one-rank, if empty tube is a double-bank, divide three in work with adapter plate, adapter plate must be fixed on the mole firmly, bores small holes around square hole, spiral nail with 5～8mm fixes, and ailhead is embedded in the adapter plate.

Fig. 7 is ventilation figure between the mole, link a pipe between mole and the mole, make ventilation mutually between the mole, this root pipe is called breather pipe 14, breather pipe is to wait mole to put into cover tire fully, be inserted in the steel basin and fixing after, the corresponding aperture (generally in the centre) that bores from the steel basin puts in, in order to operate outside, loosening nut must be longer, length is for also staying 10mm outside the steel basin after tightening, this nut 13 is enclosed within on the ventilation ozzle when flat loosely, effect is to work as to tighten this nut, and the air flue 10 of breather pipe 14 and mole is connected, and ventilates between mole, gas enters the air cavity of A piece from the valve of A piece, enters c piece at last to D piece and stop to the B piece with same method by tracheae.Because air pressure is very high, the material that is used for doing breather pipe must be a steel, and the tracheae mouth encases the air flue place must gasket seal 11, and this pad is made of the material of the false face of diesel engine.Air flue mouth 12 base portions have screw thread (air flue is 1～2mm), and diameter is 18mm, high 20mm, the outspoken footpath 8mm of air flue, high 15mm, the internal diameter of pad are 8mm, external diameter 18mm, thick 2～5mm, air flue mouth 12 and its base portion are embedded in the mole (as Fig. 7).Tracheae mouth external diameter 16mm, internal diameter 8mm (just to encase the air flue mouth for suitable, interior long 15mm, foreign minister 20mm).Interior tracheae external diameter 8～15mm, internal diameter 1～2mm, the gentle ozzle of tracheae is connected as a single entity, and loosening nut internal diameter 18mm has screw thread, and the outside is a hexagon, diameter 28mm, nut is long to be 45mm～60mm.But above data are otherwise designed also.The effect of loosening nut 13 is with the tracheae mouth and air flue is tight-lipped tightly joins.

Valve is identical with the valve of present usefulness, for valve being fixed on the mole, do the pitting of a shape such as wineglass in a centre of A piece, hollow place diameter 20mm, cheat dark 20mm, pitting diameter 8mm, the degree of depth is decided according to needs, and itself has screw thread valve, the high 20mm of threaded portion, the top of screw thread is hexagon.
