Abstract
The utility model relates to vehicle maintenance equipment, in particular to a tire inflating device which comprises an inflating pipe and a valve core wrench. One end of the valve core wrench is provided with a bayonet. A seal nut is disposed at the top of the inflating pipe. An air nozzle is connected to the middle of the inflating pipe. The bottom of the inflating pipe is provided with an internal thread or a locking seal nut. The valve core wrench is convenient for clamping and demounting a valve core with no damage of the valve core. A valve core ejector rod is inserted into the valve core to form an intake passage, so that tire pressure can reach the rated value quickly. After the vale core ejector rod is pulled out quickly, the valve core can be airtight, and no leakage occurs after full inflation. The tire inflating device is available for both inflating and deflating. After the locking seal nut of the inflating pipe is connected with one end of an inflating lengthened pipe and the internal thread at the other end of the inflating lengthened pipe is abutted to a vacuum tire and is then matched with the valve core ejector rod, the vacuum tire can be inflated and supplemented with air better.
Description
Technical field
The utility model relates to car repair equipment, particularly a kind of tire inflation unit.
Background technology
The safety of travelling for vehicle, chaufeur can regularly be safeguarded vehicle tyre, safeguard and generally be divided into two kinds: when 1, the wheel puncture leaks gas, whole tire is pulled down from vehicle, dismantle the valve inside operation of exitting again, tire after the venting is repaired, loaded valve inside again, be inflated to specified air pressure at last and finish whole handling labor.When 2, tire pressure is not enough, whole tire is pulled down from vehicle, tonifying Qi is to specified air pressure.All need in the above-mentioned handling labor tire is unloaded, this is because existing aerating equipment all is simply to be fastened in the tyre valve core place not form sealing, tire is not removed from vehicle, and dead weight of vehicle can make and form certain pressure in the tire, causes tire inflation or aerating to be difficult to reach specified atmospheric pressure value.In addition, also often occur the phenomenon of the difficult dismounting of valve inside in the actual upkeep operation, not only waste time, influence work efficiency, and may damage valve inside after the dismounting by force, travel to vehicle and bring hidden danger.
The utility model content
The purpose of this utility model be to provide a kind of dismounting quick, inflate tire inflation unit easily.
The technical scheme that its technical matters that solves the utility model adopts is:
A kind of tire inflation unit comprises appendix and valve inside spanner, and valve inside spanner one end is provided with bayonet socket; Described appendix top is provided with sealing nut, and the appendix middle part connects valve, and the appendix bottom is provided with negative thread or lock sealing nut.
Also comprise the valve inside push rod.
Described lock sealing nut is connected with inflation extension pipe one end, and the inflation extension pipe other end is provided with negative thread.
Described sealing nut and lock sealing nut are provided with the butterfly handle.
The utility model is provided with appendix, appendix and valve inside spanner and valve inside push rod are used, the convenient chucking of valve inside spanner and dismounting valve inside, can not damage valve inside, the valve inside push rod inserts and forms free air diffuser in the valve inside, makes tire pressure arrive rated value fast, extract the valve inside push rod fast out, valve inside just can form airtight, is full of the phenomenon that can not leak air behind the gas, to conventional tyre fill, tonifying Qi all can.Difference to some extent on the wheel hub structure of conventional tyre and vacuum tire, the wheel rim evagination on the vacuum tire wheel hub, the valve on the appendix is stuck on the wheel hub easily, is difficult for operating.Give that the vacuum tire dashes, during tonifying Qi, the lock sealing nut of appendix need be connected with inflation extension pipe one end, the inflation extension pipe other end is provided with negative thread and docks with the vacuum tire specially, make valve not contact with wheel hub like this, cooperating with the valve inside push rod more just can better be for the vacuum tire fills, tonifying Qi.The utility model docks with valve inside by lock sealing nut and negative thread, and favorable sealing property fills, tonifying Qi no longer needs remove a tyre, fills, the maintenance time of tonifying Qi reduces greatly, improved work efficiency.

The specific embodiment
A kind of tire inflation unit comprises appendix 1 and valve inside spanner 2 as shown in the figure, and valve inside spanner 2 one ends are provided with bayonet socket 7; Described appendix 1 top is provided with sealing nut 3, and appendix 1 middle part connects valve 4, and appendix 1 bottom arranges negative thread as shown in Figure 2, and negative thread connects comparatively convenient and swift, is applicable to that the common inner bag tire of small size fills, tonifying Qi.Appendix 1 bottom can also be equipped with lock sealing nut 5 as shown in Figure 1, and it is better that lock sealing nut 5 connects sealing properties, is applicable to can be used for all that the common inner bag tire of large scale fills, tonifying Qi.Lock sealing nut 5 on the appendix 1 also can be connected with inflation extension pipe 9 one ends as shown in Figure 3, and inflation extension pipe 9 other ends are provided with negative thread.Be specifically designed to the filling of vacuum tire, tonifying Qi.The utility model also comprises valve inside push rod 6 as shown in Figure 5.In addition, described sealing nut 3 and lock sealing nut 5 are provided with butterfly handle 8.
Earlier according to the vehicle tyre type, choose suitable tire inflation unit, the filling of the common inner bag tire of the suitable large scale of structure shown in Figure 1, tonifying Qi, the filling of the common inner bag tire of the suitable small size of structure shown in Figure 2, tonifying Qi, the filling of structure suitable vacuum tire shown in Figure 3, tonifying Qi.
When conventional tyre needs the tonifying Qi operation, directly negative thread or lock sealing nut 5 are docked with tyre valve core, screwing hermetic nut 3 forms sealing in appendix 1, to form free air diffuser in the valve inside push rod 6 insertion valve insides, by valve 4 inflations, be charged to specified air pressure valve inside push rod 6 is extracted out, the equipment of unloading is finished whole tonifying Qi work.When conventional tyre need be inflated operation, as Fig. 6, shown in Figure 7 with in the valve inside spanner 2 insertion appendixs 1, use bayonet socket 7 that valve inside is unloaded, extract valve inside spanner 2 and valve inside out, after tire safeguarded, insert valve inside spanner 2 again and tighten valve inside, extract valve inside spanner 2 backs out and insert valve inside push rod 6, to form free air diffuser in the valve inside push rod 6 insertion valve insides, screwing hermetic nut 3 forms sealing in appendix 1, by valve 4 inflations, be charged to specified air pressure valve inside push rod 6 is extracted out, the equipment of unloading is finished tire inflation work.
When the vacuum tire needs the tonifying Qi operation, the negative thread of inflation extension pipe 9 front ends is docked with tyre valve core, screwing hermetic nut 3 forms sealing in appendix 1, to form free air diffuser in the valve inside push rod 6 insertion valve insides, by valve 4 inflations, be charged to specified air pressure valve inside push rod 6 is extracted out, the equipment of unloading is finished whole vacuum tire tonifying Qi work.When the vacuum tire need be inflated operation, valve inside spanner 2 is inserted in the appendix 1, use bayonet socket 7 that valve inside is unloaded, extract valve inside spanner 2 and valve inside out, after tire safeguarded, lock sealing nut 5 on the appendix 1 is connected with inflation extension pipe 9 one ends, inflation extension pipe 9 other ends are provided with negative thread, negative thread is docked with tyre valve core, insert valve inside spanner 2 again and tighten valve inside, extract valve inside spanner 2 backs out and insert valve inside push rod 6, to form free air diffuser in the valve inside push rod 6 insertion valve insides, screwing hermetic nut 3 forms sealing in appendix 1, by valve 4 inflations, be charged to specified air pressure valve inside push rod 6 is extracted out, the equipment of unloading is finished whole vacuum tire inflation work.
