Description

The vacuum tyre automatic air supply device that has warning function

Technical field

The utility model relates to a kind of annex that is installed on motor bike, battery-driven car, the bicycle equal vacuum tire wheel, particularly a kind of in the process of riding the device of tonifying Qi and warning automatically during the not enough or gas leakage of vacuum tyre air pressure.

Background technology

Progress along with expanding economy and science; motor bike; battery-driven car; the instrument fast development of riding instead of walk such as bicycle; because vacuum tyre is simple in structure; long service life; advantage such as easy to maintenance; the tire that the former cause inner tube of a tyre and cover tire are formed is not had the vacuum tyre of the inner tube of a tyre to replace gradually yet; but the problem that vacuum tyre in use exists original tire to exist equally: people are in process by bike; regular meeting is owing to tire is caused vacuum tyre gas leakage or air pressure deficiency by unrest or other reason; cause crag-fast awkward scene; can only get off pushing away car on the way and repair the tire of changing trains, bring inconvenience to people to relevant maintenance point.For this reason, many manufacturers and knowledgeable people have carried out R and D at the problem of above-mentioned existence, do not improve way preferably but have as yet so far.

Summary of the invention

For overcoming existing vacuum tyre above shortcomings, the purpose of this utility model just provide a kind of simple and reasonable, easy to install, productive costs is low, can solve the vacuum tyre automatic air supply device that has warning function of vacuum tyre gas leakage or air pressure deficiency temporarily.

The technical scheme that its technical matters that solves the utility model adopts, it comprises cylinder block, cylinder head, piston, piston rod, piston is arranged in the cylinder block, piston rod is fixed on the piston, the end of described piston rod is fixed with pressing plate, is provided with retracing spring on the piston rod between pressing plate and the cylinder head; Cylinder block is provided with valve body, and valve body is provided with the breather check valve and the horizontally disposed outgassing nonreturn valve of vertical setting, and the air extractor duct of breather check valve and the admission port of outgassing nonreturn valve communicate with the chamber of cylinder block.

The further preferred version of the utility model, the admission port of described valve body is provided with hexagonal nuts, and the upper end of hexagonal nuts is provided with a plurality of air inlet apertures, and its inner chamber is provided with the pronunciation loudspeaker.

The further preferred version of the utility model, described breather check valve is made up of the taper valve core, stage clip and the capping that are installed in successively on the valve body vertical passage.

The further preferred version of the utility model, described outgassing nonreturn valve is made up of the taper valve core, stage clip and the capping that are installed in successively on the valve body horizontal channel.

After adopting said structure, vacuum tyre air pressure just often, the carcass distortion is little, the utility model is inoperative; When the vacuum fetal hair was given birth to gas leakage or air pressure deficiency, this device can carry out tonifying Qi automatically, and the warning of sounding a buzzer.Tire whenever turns around tonifying Qi once, guarantees that the vacuum tyre of leaking gas also can be ridden to repair the tire of changing trains to relevant maintenance point, avoids causing crag-fast awkward scene because of gas leakage in the cyclist way.Have simple and compact for structure, easy to install, reliable in function, characteristics such as economical and practical.

Fig. 1 is a structural representation of the present utility model.

Fig. 2 is the view of installing and using of the present utility model.

The specific embodiment

Fig. 1, shown in Figure 2, the specific embodiments that has the vacuum tyre automatic air supply device of warning function for the utility model is a kind of, it comprises cylinder block 5, cylinder head 8, piston 6, piston rod 18, piston 6 is arranged in the cylinder block 5, piston rod 18 is fixed on the piston 6, be with O type circle 7 on the piston 6, the end of described piston rod 18 is fixed with pressing plate 10, is provided with retracing spring 9 on the piston rod 18 between pressing plate 10 and the cylinder head 8; Cylinder block 5 is provided with valve body 15, valve body 15 is provided with the breather check valve and the horizontally disposed outgassing nonreturn valve of vertical setting, described breather check valve is made up of the taper valve core 14, stage clip 12 and the capping 11 that are installed in successively on valve body 15 vertical passages, described outgassing nonreturn valve is made up of the taper valve core 13, stage clip 12 and the capping 11 that are installed in successively on valve body 15 horizontal channels, and the air extractor duct of breather check valve and the admission port of outgassing nonreturn valve communicate with the chamber of cylinder block 5.For easy for installation, the admission port of described valve body 15 is provided with rubber cradle 4, spring washer 3 and hexagonal nuts 1; In order to allow cyclist's very first time find the air pressure deficiency that vacuum tyre occurs, the upper end of hexagonal nuts 1 is provided with a plurality of air inlet apertures, and its inner chamber is provided with pronunciation loudspeaker 2, and the air inlet aperture has certain dustproof and waterproof effect.

The utility model only is suitable for the vacuum tyre of motor bike, battery-driven car, bicycle; At first on rim plate 16, bore a mounting hole, the air extractor duct thread end of breather check valve packs in this mounting hole, the bottom guarantees outer gland sealing in the rim plate 16 by rubber cradle 4, top mounting spring packing ring 3 is also fastening with hexagonal nuts 1, spring washer 3 can be guaranteed hexagonal nuts 1 thread looseness, and carcass 17 is installed on the rim plate 16.

The utility model work is as follows, under normal inflation pressure (2.5-3.5Bar), when this device goes to extreme lower position with wheel, carcass 17 may push pressing plate 10, pressing plate 10 is by the air in piston rod 18 and the piston 6 compressed gas cylinder bodies 5, but because amount of compression is not enough, this device is inoperative.If leaking air, vacuum tyre cause air pressure to descend gradually or air pressure when not enough (1-1.4Bar), the amount of compression of carcass 17 strengthens, pressing plate 10 is by piston rod 18 and piston 6 compressed gas cylinder bodies 5 inner chamber air, the air pressure of cylinder block 5 inner chambers is greater than the air pressure of carcass 17 inner chambers, taper valve core 13 is backed down after overcoming the elastic force of stage clip 12, and the air of cylinder block 5 inner chambers is inflated to carcass 17 inner chambers.After the air pressure equilibrium of the air pressure of carcass 17 and cylinder block 5 inner chambers, taper valve core 13 automatically resets and closes inflation inlet under the effect of stage clip 12, thereby finishes automatic tonifying Qi work.After this device left extreme lower position with wheel, under the effect of retracing spring 9, pressing plate 10, piston rod 18 and piston 6 resetted, and piston 6 is by drop-down, and negative pressure appears in cylinder block 5 inner chambers, the taper valve core 14 of breather check valve overcome open behind the elastic force of stage clip 12 air-breathing.The air of being inhaled is by pronunciation during loudspeaker 2, warnings of can sounding a buzzer, the prompting person for driving a car note tire the air pressure deficiency, want on-call maintenance.When the air pressure of cylinder block 5 inner chambers with extraneous one to the time, taper valve core 14 under stage clip 12 effects, on move and close breather check valve, thereby finish work air-breathing and that report to the police.When this device turns over a circle when arrive extreme lower position again with wheel, a beginning new round is inflated and air-breathing circulation, and promptly tire whenever turns around, circulation primary.
