Embodiment
With reference to specific embodiment, the utility model is expanded on further.It should be understood that these embodiments are merely to illustrate this
Utility model rather than limitation the scope of the utility model.In addition, it is to be understood that reading the content of the utility model instruction
Afterwards, those skilled in the art can make various changes or modifications to the utility model, and these equivalent form of values equally fall within this Shen
Please appended claims limited range.
As Figure 1-5, embodiment of the present utility model is related to a kind of unidirectional pumping air valve for vacuum compression bag,
It is close to axial including pumping seat 1 and base 2, described pumping seat 1 and base 2, one end of described pumping seat 1 is interior between two parties
Portion is disposed with flat air exhaust nozzle 6, and described pumping seat 1 is internally embedded the cylinder for installing the oriented axially extending stretching of the other end
Shape plug socket 7, the inner side of described base 2 are embedded in the spine seat 3 for being provided with middle part perforate towards pumping seat 1, and the one of the spine seat 3
End is extend into cylindrical plug socket 7.
The madial wall of described cylindrical plug socket 7 is disposed with several raised cards 8 around even circumferential, for clamping
Spacing spine seat 3.
Described raised card 8 is disposed with inclined-plane towards one end of flat air exhaust nozzle 6, facilitates spine seat 3 and cylinder
Plug socket 7 departs from, and realizes the dismounting of air valve.
Described spine seat 3 includes the axially extending sharp portion 12 of bottom plate 11 and the side of bottom plate 11, and the insertion of bottom plate 11 is solid
It is scheduled in base 2, the bottom of the sharp portion 12 is disposed with a circle protrusion step 13, and the protrusion step 13 is towards cylindrical plug socket
7 one end is disposed with a circle inclined-plane, and protrusion step 13 can realize limit with the snapping of raised card 8 on cylindrical plug socket 7
Position, and the effect on inclined-plane is also for facilitating spine seat 3 to be inserted into cylindrical plug socket 7.
Described pumping seat 1 and the opposing sidewalls of base 2 are the high circular conical surface 4 of middle low surrounding, are evacuated seat 1 and base
When 2 mutual extruding, circular conical surface 4 can produce deformation, realize and clamp plastic foil.
Location arrangements on the circular conical surface 4 of described pumping seat 1 side close to cylindrical plug socket 7 have a circle seal convexity
5, seal convexity 5 can place gas leakage when seat 1 is evacuated and base 2 compresses.
