Embodiment
In order that content of the present utility model is easier to be clearly understood, below according to specific embodiment and combine attached
Figure, is described in further detail to the utility model.
A kind of Portable inflating device as shown in Figure 1 to Figure 3, including enclosing cover 1 and the workpiece 2 that is located in enclosing cover 1,
The enclosing cover 1 includes upper lid 1.1 and lower cover 1.2, and upper lid 1.1 and lower cover 1.2 are bolted, and upper lid 1.1 is provided with uniform
The screw hole 1.3 of arrangement.The upper upper surface of lid 1.1 is provided with air admission hole 3, and the side of lower cover 1.2 is provided with venthole 4, and venthole 4 passes through
Flexible pipe is connected with inflation appliance to be needed.The workpiece 2 includes bent axle 2.1, left cylinder 2.2 and right cylinder 2.3, the left gas
First piston 2.4 and second piston 2.9 are equipped with cylinder 2.2 and right cylinder 2.3, one end of the first piston 2.4 passes through company
Bar 2.5 is connected with the bent axle 2.1, the connection of second piston 2.9 guide pillar 2.6, in the left cylinder 2.2 and right cylinder 2.3
Be equipped with outgassing nonreturn valve 5 and breather check valve 6, the outgassing nonreturn valve 5 is connected with venthole 4, the breather check valve 6 with
Air admission hole 3 is connected, and the workpiece 2 also includes the rocking bar 2.7 being connected with bent axle 2.1, and rocking bar 2.7 is provided with handle 2.8.Institute
State the middle part of enclosing cover 1 and be provided with the bearing groove 7 for accommodating bent axle 2.1.
Workpiece 2 for convenience of maintenance and renewal part is disassembled at any time, with enclosing cover 1 using snap consolidated by workpiece 2
It is fixed.Each part is fixed formula using buckle and connects to form entirety in addition to enclosing cover 1.
Operation principle of the present utility model is as follows：
