The upper surface of inflator is provided with the annular convex platform of protrusion, and the annular convex platform coordinates with annular groove, in annular groove wall and ring
Pin hole is provided on shape boss wall, the upper inflator and lower inflator are fixed together by pin across pin hole, in the inflator
Interior sealing and it is slidably provided with piston, piston upper end is provided with push rod, the push rod is retractable structure, in push rod end
Spring is provided between portion and air cylinder cover；It is additionally provided with sealing ring in the annular convex platform upper end；It is opened on the piston ring wall
Equipped with ring fillister, the ring fillister is provided with sealing ring, the sealing ring is in ┣ types, horizontal line part and interior concave ring
Shape slot coordinates, and vertical portion outer end face is arc.
Further：The push rod is that stretching structure is：Outer bar is screw-thread fit with interior bar, and screw pitch is set as 5mm.
Further：It is provided with hole on the lower inflator lower end base side wall, check valve is provided on the hole, described
Lower inflator bottom is provided with foldable footrest portion.
Advantageous effect
The utility model has the beneficial effects that：By the way that inflator is divided into two parts, it is possible to reduce the length of inflator, simultaneously
Push rod is arranged to stretching structure, push rod length can be designed to shorter, when needed, two parts inflator is connected
Connect it is fixed after, push rod is pulled out to suitable length, so that it may which to be inflated, this is simple in structure, and easy to carry fills simultaneously
Gas velocity degree and volumetric efficiency are all relatively good, and low manufacture cost.
Description of the drawings
Fig. 1 is the structural schematic diagram of the utility model assembling inflator
Fig. 2 is the structural schematic diagram that sealing ring is arranged on piston
Specific implementation mode
As a kind of embodiment of the utility model, as shown in Figure 1, 2, a kind of detachable inflator, including inflator
And the tracheae 71 being connected with tire suction nozzle mounted on inflator bottom, it is characterised in that：The inflator is divided into 3 He of inflator
Lower inflator 7, annular groove 5 is provided in the lower face of upper inflator, and the upper surface of lower inflator is provided with the annular convex platform of protrusion
6, the annular convex platform coordinates with annular groove, and pin hole, the upper inflator are provided on annular groove wall and annular convex platform wall
And lower inflator is fixed together by pin across pin hole, in the inflator interior sealing and slidably piston 4 is provided with, in work
End is provided with push rod beyond the Great Wall, and the push rod is retractable structure, and spring 22 is provided between push rod end and air cylinder cover 21.It should
Structure can when not in use remove two parts inflator separated, push rod can also be torn open from air cylinder cover certainly
Under, ensure that its length shortens, it is easy to carry, when needing to use, spring pocket is mounted in after two parts inflator is connected
On push rod, push rod is connect with piston, it can also be screw-thread fit that push rod, which can be secure fit with piston, here, herein no longer
Description；It can be carried out operating.By the way that inflator is divided into two parts, it is possible to reduce the length of inflator, while push rod being arranged
At stretching structure, push rod length can be designed to it is shorter, when needed, after two parts inflator is connected and fixed,
Push rod is pulled out to suitable length, so that it may to be inflated, this is simple in structure, and easy to carry while aeration speed and
Volumetric efficiency is all relatively good, and low manufacture cost.
In the present embodiment：It is additionally provided with sealing ring 8 in the annular convex platform upper end.It can increase conjunction by the way that sealing ring is arranged
The sealing for holding together portion prevents its gas leakage.
In the present embodiment：Ring fillister 10 is offered on the piston ring wall, is provided in the ring fillister
Sealing ring 9, the sealing ring are in ┣ types, and horizontal line part coordinates with ring fillister, and vertical portion outer end face is arc.The structure
By the way that ┣ type sealing rings are arranged, stability of the sealing ring on piston can be increased, while outer end face is designed into camber, it can be with
So that reducing the resistance brought end face when passage process up and down.
In the present embodiment：The push rod stretching structure is：Outer bar 1 is screw-thread fit with interior bar 2, and screw pitch is set as 5mm.
The structure is easy to adjust, and since screw pitch is designed to 5mm, than very fast when adjustment length or folding.
In the present embodiment：It is provided with hole 12 on the lower inflator lower end base side wall, check valve is provided on the hole,
The lower inflator bottom is provided with foldable footrest portion 11.It can be moved down to wheel in push rod by providing holes and check valve
Tire inflate when check valve be close, will not gas leakage, when push rod band piston move up when, check valve open, air into
Enter, is inflator make-up gas.Here it since check valve and the installation cooperation structure in hole are mature technology, is not repeated herein.
Footrest portion is identical as original inflator structure, no longer describes herein.
