Description

The tire pressure rifle of can bleeding

Technical field

The utility model relates to a kind of tire pressure rifle, particularly a kind of tire pressure rifle that gathers multi-function in integral whole.

Background technology

As everyone knows, the tire pressure rifle is the outfit of automobile and vehicle tires such as self-propelled vehicle and motor bike, by inflation of tire and pressure test are guaranteed that the inner pressure of tire of vehicle remains in the safe handling scope.But along with the development of society and the progress of science and technology, there are many tires to use nitrogen now, when inflated with nitrogen, also need the tire processing of bleeding, because the function that the tire pressure rifle is not bled, when inflated with nitrogen, have to be equipped with the rifle of bleeding again, use by turns with the tire pressure rifle, the user uses very inconvenience.Speed is slow when automobile inner tube is exitted in addition, needs with the hands extruding.Therefore, develop a kind of can not only the inflation, and can bleed and the tire pressure rifle of drifting dust is a urgent problem.For this reason, many manufacturers and knowledgeable people have carried out the R and D of fruitful ground, but do not have rational product to emerge so far as yet.

Summary of the invention

In order to overcome the above-mentioned disadvantage that existing tire pressure rifle exists, the purpose of this utility model provide a kind of simple and reasonable, easy to operate, use bled tire pressure rifles reliable, that function is many.

The technical scheme that its technical matters that solves the utility model adopts, it comprises rifle body, switch, be provided with free air diffuser, internal channel and exit passageway in the rifle body, the import of switch is connected with free air diffuser, and the outlet of switch is connected with internal channel, and exit passageway links to each other with internal channel, the import of free air diffuser is connected with and source of the gas bonded assembly inlet suction port, in the described exit passageway nozzle is installed, the exit passageway outlet is fixed with air valve, and the spout of nozzle and air valve passage are on same axis; On the exit passageway between nozzle and the air valve, be provided with working interface, be fixed with working joint on the working interface.

For convenience of the measuring pulley air pressure, described exit passageway is provided with the air-pressure gauge interface, is fixed with air-pressure gauge on the air-pressure gauge interface.

In order to realize the function of bleeding, the cross section of described air valve passage is much larger than the nozzle exit of nozzle, and the import of air valve passage is an exit skirt.

Bleed a tire for convenience, on the rifle body between internal channel and the exit passageway, be provided with air cock.

After adopting said structure, the utility model has following advantage and effect: the one, and when operating valve lever drive spool made air valve be in closed condition, by adopting different working joints, operating switch promptly can be realized inflating, the function of drifting dust, survey air pressure and venting; The 2nd, when operating valve lever drove spool and makes air valve be in open mode, operating switch promptly can be realized the function of bleeding, and uses the tire pressure rifle to bleed, and can accelerate inner tube deflation speed greatly; The 3rd, the field of application of tire pressure rifle is further expanded, the many usefulness of a rifle, and function is more complete.

The specific embodiment

Illustrated in figures 1 and 2, be can the bleed specific embodiments of tire pressure rifle of the utility model, it comprises rifle body 3, switch 19, be provided with free air diffuser 2 in the rifle body 3, internal channel 5 and exit passageway 7, the import of switch 19 is connected with free air diffuser 2, the outlet of switch 19 is connected with internal channel 5, the import of free air diffuser 2 is connected with and source of the gas bonded assembly inlet suction port 1, in the described exit passageway 7 nozzle 10 is installed, the outlet of exit passageway 7 is fixed with air valve 13, the spout of nozzle 10 and air valve passage 14 are on same axis, and the cross section of described air valve passage 14 is much larger than the nozzle exit of nozzle 10, and the import of air valve passage 14 is an exit skirt; On the exit passageway between nozzle 10 and the air valve 14, be provided with working interface 16, be fixed with working joint 15 on the working interface 16.Described exit passageway 7 is provided with air-pressure gauge interface 8, is fixed with air-pressure gauge 9 on the air-pressure gauge interface 8.On the rifle body 3 between internal channel 5 and the exit passageway 7, be provided with air cock 6.Described working joint 15 is to charge and discharge gas and the working joint of bleeding, drifting dust working joint wherein a kind of, in inflation, survey air pressure, exit, use when bleeding and charge and discharge gas and the working joint of bleeding, uses the drifting dust working joint when drifting dust.

When operating valve lever 11 drive spools 12 make air valve 13 be in closed condition, as shown in Figure 1, can realize inflating, surveying the function of air pressure, venting and drifting dust, its working process is as follows: when inflation of tire, Push switch spanner 17, switch 19 is connected after driving the elastic force that switch valve rod 18 overcomes switch spring 4, gas is from inlet suction port 1, free air diffuser 2 and enter 15 pairs of tires of working joint by switch 19, internal channel 5, exit passageway 7, nozzle 10, working interface 16 and put on the air, and can realize the function to inflation of tire.In gas replenishment process as will watch tire pressure, trip switch spanner 18, off switch 19 can realize surveying the function of air pressure.When the too high air pressure that maybe will bleed off in the tire of air pressure in the gas replenishment process, trip switch spanner 18, off switch 19, press air cock 6, air cock 6 is in and the atmosphere on-state, air pressure in the tire enters air cock 6 through working joint 15, working interface 16, nozzle 10, exit passageway 7 and carries out exhaust, thereby realizes the function to bleeding a tire.During drifting dust, working joint 15 uses the drifting dust working joint, Push switch spanner 17, switch 19 is connected after driving the elastic force that switch valve rod 18 overcomes switch spring 4, gas enters working joint 15 from inlet suction port 1, free air diffuser 2 and by switch 19, internal channel 5, exit passageway 7, nozzle 10, working interface 16, can realize the function of drifting dust.

When operating valve lever 11 drive spools 12 make air valve 13 be in open mode, as shown in Figure 2, working joint 15 is connected on the tire that will bleed, can realize the function of bleeding, its working process is as follows: Push switch spanner 17, switch 19 is connected after driving the elastic force that switch valve rod 18 overcomes switch spring 4, gas is from inlet suction port 1, free air diffuser 2 also passes through switch 19, internal channel 5, air cock 6, exit passageway 7 enters nozzle 10, nozzle 10 with spraying high-pressure gas to air valve 13 and from air valve passage 14, discharge, in nozzle 10 inject high pressure gas processes, because the cross section of air valve passage 14 is much larger than the cross section of nozzle 10, make working interface 16 places produce negative pressure, the gas in the tire is extracted out and discharged, thereby can realize the function of bleeding from air valve passage 14.
