Abstract
The utility model relates to an automatic inflating pump used for a vehicle with inflating tyres. The automatic inflating pump used for a vehicle with inflating tyres is composed of a pump body, a piston, a connecting rod, a connecting shaft, and an eccentric wheel. The entire automatic inflating pump used for a vehicle with inflating tyres is arranged on the rotary shaft position of a vehicle spoke by a bracket and a fixing ring. Automatic inflation in the process of riding can be realized. After inflation is finished, a wheel is reversely turned, the inflation can be stopped. The automatic inflating pump used for a vehicle with inflating tyres has simple structure and convenient installation. Due to the fact that a dustproof sealed device is adopted, and dust and mud water do not easily enter the automatic inflating pump used for a vehicle with inflating tyres. The automatic inflating pump used for a vehicle with inflating tyres can be applicable to the inflation of a vehicle when the vehicle runs on various road surfaces.
Description
The utility model relates to a kind of self-filler that possesses the airtyred vehicle (bicycle, three-wheel vehicle, motor bike etc.).
At present, the general various common inflator that uses is very heavy, carries and use equal inconvenience.Bicycle or three-wheel vehicle in the process of riding as the tyre pressure deficiency, leak slowly or pricked, just can't travel, bring very big inconvenience to the end user.Before the present patent application, once met the miniature inflation pump of a kind of bicycle.It is to be loaded on the bicycle shaft outside, and therefore the integral structure blowing-by is easy to enter dust and muddy water.Its charge air is less in addition, only is applicable to some bicycle.
The purpose of this utility model just for fear of the deficiency of above-mentioned prior art and a kind ofly being easy to carry of providing, can gas filed at any time totally-enclosed new type auto inflation pump in the process of riding.
The purpose of this utility model is to realize by following measure: be loaded on the inflation pump on the wheel shaft, be equipped with in the cylinder pump housing under piston, the piston and be connected with connecting rod, adapter shaft one end in the connecting rod is set with spring, the other end stretches out from connecting rod with eccentric wheel and links to each other, and the pump housing is loaded on the wheel hub by support and set collar.
Below by accompanying drawing the utility model is elaborated:
Fig. 1 is integral structure figure
Description of drawings: 1-eccentric wheel 2-connecting axle 3-connecting rod 4-pump housing 5-air nozzle 6-pressure regulator valve 7-support 8-retainer ring 9-piston 10-strap 11-piston pin 12-spring 13-sealing ring 14-wool felt 15-fixed card 16-sealing malthoid 17-seal cover 18-tracheae 19-ventilation packing ring
The pump housing 4 is a hollow cylinder, and piston 9 is housed in it.Piston links to each other with connecting rod 3 by piston pin 11, and the lower end of connecting rod is processed with the cross bar vertical with connecting rod, and two sections holes that diameter is different are processed in inside.Adapter shaft 2 is loaded in the hole.One end of adapter shaft is set with spring 12.Spring just in time is stuck on the pillow block, and the termination is equipped with ventilation packing ring 19 and is passed through bolted.The other end stretches out from the hole of minor diameter, and links to each other with eccentric wheel 1.Eccentric wheel links to each other with wheel hub by the eccentric wheel packing ring.13 sealings of two seal rings are adopted in the upper end of piston.Piston lower end (being the connecting rod lower end) is to realize by fixed card 15, sealing malthoid 16 and seal cover cap 17 that stearic plastics are made with the sealing of the pump housing.
Pump housing top is equipped with that pressure regulating valve 6 gentlely chews 5, tracheae 18.The pump housing one side is equipped with strap 10.Whole air pump is fixed in the center of wheel spoke by support 7 and set collar 8, and strap is fixed by bolt and spoke and made whole pump housing location reliably simultaneously, and is easy for installation.
When wheel, the eccentric wheel that is loaded on the wheel shaft is made upper and lower crank motion by the piston that the adapter shaft drive links to each other with connecting rod.When piston is shifted to pump cover one end, air enters pump housing seal ring this moment and shifts to piston tip from gap that connecting rod lower end and support form by the malthoid and the breach on the piston of ventilation packing ring on connecting rod inner via hole and the piston valve, when inflation of tire, thereby seal ring moves to the piston lower end and plays sealing function.Air with certain pressure by gas chew, tracheae enters tire, reaches automatic gas filed purpose in the process of riding.Inflation pressure can be regulated size by pressure regulating valve, when inflation finishes, as long as make wheel reversing, just adapter shaft is freed with eccentric hook voluntarily, stops gas filed purpose thereby reach.
Claims (4)
1, a kind of all-sealed new type auto inflation pump, comprise that the pump housing, gas are chewed, support, set collar, it is characterized in that being loaded on the automatic inflation pump on the wheel shaft, the pump housing is a cylinder, and piston is equipped with in inside, the piston bottom is connected with connecting rod, adapter shaft is housed in the connecting rod, and adapter shaft one end is set with spring, and the other end stretches out from connecting rod with eccentric wheel and links to each other, whole air pump is loaded in the rotating shaft of wheel spoke by support and set collar, and eccentric wheel is loaded on the wheel hub.
2, automatic inflation pump as claimed in claim 1 is characterized in that having adopted in the pump housing exclusion seal device and double density seal hermetically-sealed construction, and it is made up of two seal rings of piston upper end and stearic plastic sheet, sealing malthoid and the seal cover cap of lower end.
3, automatic inflation pump as claimed in claim 1 is characterized in that inflation pump is fixed on the center of wheel spoke by support and dead ring, and the pump housing one side is equipped with strap and fixes by bolt and spoke and make whole pump housing location reliable, easy for installation.
4, automatic inflation pump as claimed in claim 1 is characterized in that the spring-loaded end termination of adapter shaft also is equipped with the ventilation packing ring.
