Gas efficiency can reach the purpose of " convenient, time saving, laborsaving ", be more in line with people to tool-class product in use relax
Fit convenient needs；(2) it can avoid occurring push-and-pull state partially in use using symmetrical double transmission rod push-and-pull designs, so that
Using more stable, the risk of internal structure failure is reduced；(3) linking of each section composition is complete, has and saves space, access side
Just the characteristics of.
Detailed description of the invention
Fig. 1 is a kind of main view of the double drive rod inflators of hand-rail type of the utility model；
Fig. 2 is a kind of side view of the double drive rod inflators of hand-rail type of the utility model.
In figure, 1. sealed cylinders, 2. pistons, 3. connecting rods, 4. the 4th gears, 5. second turntables, 6. driving devices, 7. second
Gear, 8. first gears, 9. shafts, 10. second turntables, 11. third gears, 12. air inlets, 13. gas outlets.
Specific embodiment
The technical solution of the utility model is described in further detail below in conjunction with Detailed description of the invention and specific embodiment.
As shown in Figure 1, a kind of double drive rod inflators of hand-rail type of the utility model, including sealed cylinder 1, the sealing drum
Rotation is provided with intermeshing first gear 8 and second gear 7 in horizontal direction in body 1, and second gear 7 is circumscribed with driving dress
