Pressure, when compression blocks 58 move up, sealing block 96 is subject to the top that cavity 91 is moved in the effect of 86 elastic force of holddown spring, sealing
96 upper surface of block is abutted against with 91 upper end inner wall of cavity, and protrusion 93 is pressed into recess 94, at this time one-way air inlet mouth 95 with it is unidirectional
Gas outlet 84 completely cuts off, while air pressure constantly increases in the first compression groove 22, and 12 bottom of lifting column is subject to the first compression groove 22
The pressure of mesohigh air constantly rises, when lifting column 12 rises to top, the first spacing block set 111 and the second limited block
121 abut against, and lifting column 12 stops rising at this time, and the 22 hollow air pressure of the first compression groove, which is greater than or equal in high-pressure chamber 41 by force, to be preset
Atmospheric pressure when, sealing block 38 moves up, and exposes gas vent 33 and bleeder port 36, at this time gas vent 33 and 36 communications and liaison of bleeder port,
Pressure-air in first compression groove 22 releases, when the atmospheric pressure in the first compression groove 22 is less than preset air in high-pressure chamber 41
During pressure values, sealing block 38, which is moved down, isolates gas vent 33 with bleeder port 36, prevents lifting column 12 from falling suddenly, while also ensures
Atmospheric pressure is unlikely to excessively high so as to damaging device in first compression groove 22.
The beneficial effects of the invention are as follows：The configuration of the present invention is simple, it is easy to operate, before use, first by fore-set top to suitable
Highly, while by air-outlet valve by outlet cross-drilled hole in isolation, simultaneously as the pressure of gas is larger in high-pressure chamber, it is close
Envelope block is subject to the pressure effect of pressure-air in high-pressure chamber to be displaced downwardly to high-pressure chamber lowermost end, gas vent and bleeder port is completely cut off, together
When inflate engine and start, rotated by rotary column band movable eccentric wheel, and then passive runner is driven to move up and down, and then pass through movement
Column drives compression blocks to be moved up and down in the second compression groove, and when compression blocks move down, sealing block is subject to atmospheric pressure to make during inflation
It is moved down in holddown spring, the air compressed in the second compression groove enters one-way air inlet mouth by air-filled pore, then leads to successively
One-way air inlet mouth, air inlet cross-drilled hole, ventilation vertical core, the constantly pressurising into the first compression groove of unidirectional gas outlet are crossed, is moved up in compression blocks
When, sealing block is subject to the top that cavity is moved in the effect of holddown spring elastic force, sealing block upper surface and cavity upper end inner wall
It abuts against, in protrusion press-in recess, one-way air inlet mouth completely cuts off with unidirectional gas outlet at this time, while the hollow air pressure of the first compression groove
Power constantly increases, and lifting column bottom is subject to the pressure of the first compression groove mesohigh air constantly to rise, when lifting column rises to most
