Base press-in internal frame body in；Hereafter, operating personnel pass through the operation repeatedly to vacuumizing assembly, you can simple, effective complete
The extraction of air in paired packaging bag；And some port lids are effectively pushed down being evacuated to after vacuum state in the presence of atmospheric pressure,
To keep vacuum state.The present invention solves the drawbacks of maximum in the prior art when in use, that is, realizes without other
External vaccum-pumping equipment purpose, although the level of vacuum of packaging bag is not high after the completion of use, daily life can be met
It is required, so that this case has smaller volume and the more extensive scope of application, and can use under circumstances（Nothing
Power source or during without other external equipments）, have delicate structure, easy to use, stability good on the whole and the scope of application
The characteristics of wide.
Here is two kinds of embodiments that this case proposes for the structure of piston driving assembly, to make representative explanation：
Embodiment one：The piston driving assembly 41 includes rotating seat 411 and center-pole 412；
The rotating seat 411 is in up big and down small ladder shaft-like, the bottom of the rotating seat 411 stretched into pedestal 32,
And fitted with the inwall of pedestal 32, the top of the rotating seat 411 is erected on the top surface of pedestal 32, the rotating seat 411
Inside offer a screwed hole 4110；
The center-pole 412 is located in the screwed hole 4110 and the bottom of center-pole 412 pass through connecting rod with base 3
The bottom of pedestal 32 is fixedly connected, and the top of the center-pole 412 is also fixedly connected with restraining position ring block 4120；
The middle part of the piston 421 offers to be offered on the outer wall of the slide opening being adapted to center-pole 412 and piston 421
The external screw thread being adapted to screwed hole 4110, the piston 421 are socketed center-pole 412 and are threadedly coupled with screwed hole 4110.This
Sample, piston can be effectively driven to be pumped in screwed hole when the forward and reverse turn rotating seat of operating personnel, so as to
Eventually through the routing motion with port lid on piston-top surface to carrying out vacuum pumping in packaging bag.
The top surface of the pedestal 32 is fixedly connected with a ring-shaped guide rail 320, is opened on the bottom surface on the top of the rotating seat 411
Provided with the ring-type guide groove being adapted to ring-shaped guide rail 320.So as to cause the relative motion of rotating seat and base more stable, suitable
Freely.
The section of the ring-shaped guide rail 320 is in T shape or inverted trapezoidal.So as to cause the relative motion of rotating seat and base
While more stable, smooth so that rotating seat keeps being bonded with the base moment.
The section of the center-pole 412 is in in-line or cross.Thereby further ensure that piston only can be in screwed hole
Pump.
Embodiment two：The piston driving assembly 41 includes slide 413, connecting rod 414, gland 415 and stage clip 416；
The slide 413 is located in pedestal 32 and is fixedly connected with the inwall of pedestal 32, and the middle part of the slide 413 is opened
Provided with a vertical slide opening 4130, the piston 421 be slidably connected in the vertical slide opening 4130 and with vertical slide opening 4130
Inwall hermetic seal；
The side of the gland 415 is hinged on the top surface of slide 413 and the top stationary phase of opposite side and stage clip 416
Even, the bottom of the stage clip 416 is then fixedly connected on the top surface of slide 413, and the both ends of the connecting rod 414 are respectively hinged at pressure
On the bottom surface of lid 415 and the top surface of piston 421.So, operating personnel push gland and may be such that descent of piston, port lid are beaten every time
Open, so as to the air in extraction section packaging bag；And each jack-up gland action of stage clip, piston stroking upward can be driven, so as to
It is simple during operating personnel repeatedly push gland repeatedly, be efficiently completed vacuum pumping to packaging bag.
Here is the sealing structure that this case proposes for the hermetic seal between piston and slide：The outside of the piston 421
Some annular recess are offered on wall, sealing ring one is equipped with the annular recess；On the apical margin and root edge of the piston 421
It has been fixedly connected with sealing ring two.It has easy to use, stability good and the characteristics of good sealing effect.
It is connected through a screw thread between the slide 413 and base 32.So that the demolition, installation of slide are more simple, maintenance,
Change more convenient.
