Abstract

The utility model relates to a minitype inflating device for a motor vehicle tyre. The minitype inflating device for a motor vehicle tyre is composed of an inflating nozzle, an air inlet joint, a hose, and ai air outlet joint. The minitype inflating device for a motor vehicle tyre is mainly characterized in that a power source is not needed to be additionally added, and compression air inside the per se cylinder of a motor vehicle is used to pass through the minitype inflating device for a motor vehicle tyre to inflate for a tyre. The problem that the cost of the inflation using a compressor is high is solved. The tyre generates perforation when a user works outdoors, after the tyre is repaired, the minitype inflating device for a motor vehicle tyre is adopted, and the tyre can fast obtain inflation.

Description

The automobile tyre mini inflatable device

The utility model relates to the device of giving inflation of tire by self-propelled vehicle self cylinder.

Traditional automobile tyre inflatable appliance generally adopts compressor (or claiming air pump), it realizes gas replenishment process by the motion of machine inner carrier, but volume is big, cost is high, and general car owner is difficult to bear, secondly, adopt manual pump, though volume is little, reduced cost, charge efficiency is low, service life is short, and the pressure that needs in the very difficult assurance automobile tyre.

In view of the problem that above-mentioned existing device exists, task of the present utility model provides that a kind of volume is little, cost is low, easy to use, automobile tyre mini inflatable device that charge efficiency is high.

The method that solves above-mentioned task is: utilize pressurized air in the self-propelled vehicle cylinder as gas filed gas source, piston motion connects air outlet adapter and inlet suction port as the inflation propulsion source respectively with flexible pipe two ends, the inlet suction port charging connector that spins again; For diesel engine, charging connector is connected with spraying nipple interface in the cylinder, and the connection of spark ignition engine is the light-up plug interface in cylinder, and the feasibility of this method is that atmospheric pressure in the cylinder is greater than the pressure in the tire, as: pressure is 7-11kg/cm in the four-stroke spark ignition engine, cylinder ², pressure is 11-15kg/cm in the cylinder of diesel engine ², and pressure generally is no more than 6kg/cm in the automobile tyre ²,, just can realize giving the inflation of tire process as long as in charging connector, adorn an one-way cock.For the pressure that embodies in the tire directly perceived, also can on charging connector, be communicated with a compression indicator.

Adopt above-mentioned connection mode, can produce the problem of waste fuel oil, certainly, just do not exist for single cylinder engine, because inflation power is that fuel cock is (the single cylinder motor bike) of closing in advance by foot-operated or hand, and to multi-cylinder diesel engine, during inflation, only utilize the pressure gas in wherein arbitrary cylinder, take off spraying nipple, set up charging connector, inflate than cylinder piston motion by all the other several cylinder work drives, but still oil spout of the spraying nipple that takes off, these need are caught with a small container and are got final product; For multi-cylinder gasoline engine,, misfire though be used for compressed-air actuated that cylinder because fuel oil enters from carburettor, but air is brought atomization gas into, and the gas after compression this moment is a mixture gas, to the big influence of tire nothing, add that inflationtime is short, oil inlet quantity is also few.

The gas replenishment process of this device application four-stroke engine is as follows: first stroke is a breathing process, and bent axle changes half-turn; Second stroke is a compression process, and bent axle changes half-turn, at this moment, opens under pressure with the one-way cock in the charging connector of this cylinder junction, and pressure gas flows to by flexible pipe that third trip is the ignition process in the tire, the burning that misfires of this cylinder, bent axle commentaries on classics half-turn; The fourth line journey is an exhaust process, thus the time cylinder in pressure strong less than inner pressure of tire, one-way cock is closed, so far, bent axle takes two turns, finishes gas replenishment process one time, circulates like this and, till sufficient gas.

Gas filled device of the present utility model is simple in structure, and the efficient height is easy to use, is specially adapted to the fraction horsepower self-propelled vehicle.

An embodiment of the present utility model now is described in detail in detail in conjunction with the accompanying drawings:

Fig. 1 is a schematic perspective view of the present utility model;

Fig. 2 is the charging connector cutaway view among Fig. 1;

Fig. 3 is the partial enlarged drawing of one-way cock among Fig. 2;

Fig. 4 is the left view of Fig. 3.

With reference to Fig. 1, Fig. 2, this device is made up of air outlet adapter " 1 ", flexible pipe " 2 ", inlet suction port " 3 ", charging connector " 4 " four parts.Air outlet adapter " 1 " is as being connected with the tire admission piece, and charging connector " 4 " is as being connected with self-propelled vehicle cylinder light-up plug interface or spraying nipple interface, and its other end and inlet suction port " 3 " spin; Inward turning one one-way cock " 5 " in the charging connector " 4 ", it is only opened when cylinder operation enters compression stroke, and pressure gas enters tire by flexible pipe " 2 ".

With reference to Fig. 3, Fig. 4, this one-way cock " 5 " is made up of rotation set " 6 ", flaps " 7 ", resistance draw point " 8 " and valve plates " 9 ".Their assembling mode is: flaps " 7 " is affixed with rotation set " a 6 " end, but do not seal the rotation set mouth fully, resistance draw point " 8 " passes flaps " 7 " and is connected valve plates " 9 " again with rotation set " 6 ", this valve plates " 9 " is made encapsulation process on every side, can seal rotation set " 6 " other end, and bear the interior pressure of tire, make it indeformable.

Claims

1, self-propelled vehicle self cylinder of a kind of band flexible pipe " 2 " is given the device of inflation of tire, the inlet suction port " 3 " that is characterised in that flexible pipe " a 2 " the end of the present utility model charging connector " 4 " that spins is connected with spraying nipple or light-up plug interface head in the engine cylinder, and the admission piece that the other end takes on gas joint " 1 " and tire spins; Adorn an one-way cock " 5 " in the charging connector " 4 " again, only when engine cylinder is operated in compression stroke, open.

2, gas filled device according to claim 1, it is characterized in that one-way cock " 5 " is made up of rotation set " 6 ", flaps " 7 ", resistance draw point " 8 " and valve plates " 9 ", their assembling mode is: flaps " 7 " and rotation set " a 6 " end are affixed, and resistance draw point " 8 " passes in flaps " 7 " and the rotation set " 6 " and is connected valve plates " 9 " again.
