Inflation pedal

Technical field

Present design relates to design and the manufacture of daily necessities, particularly belongs to inflate pedal.

Background technology

For many years, when people commonly use bicycle, large flatbed tricycle, basketball, balloon etc. need inflation All must rely on inflator.This old-fashioned inflator or length or short, thick or thin, all must make with the hands to grasp Make；Dexterous hand can not do the thing of a little other necessity again.And, inflator is landed in use must Knee-action, uncomfortable with allowing people's repeatedly hunch, uneasy.Have a kind of at factory or dress The period of the day from 11 p.m. to 1 a.m of repairing the house, for blowing down the thing of chip and dust, looks exactly like the scissors of pruningization band, and it is also " to tie " both hands, the gas blown does not continues, uneven.To automobile, motorcycle, electronic help The general family of electric inflater and office, the unit of the inflation of power car are not needed yet.

Summary of the invention

The purpose of project of the present invention is design, manufacture a kind of new-type inflatable tool inflates one by one and steps on Plate, too big and " bundle " hand, tiring old-fashioned inflator with replacement " age ".Inflation pedal knot Structure is simple, and material is common, it is simple to manufacture and use.

The technical scheme of this project is as follows:

First, panel and the base plate of pedal is inflated with the ferroalloy manufacture being difficult to get rusty.Rectangular The panel of shape is isometric with base plate, wide.Their main part length 24 centimetres, wide 10 centimetres. One end that panel and base plate are drawn close is hinged, and its angle is 26 degree.Their other end, One " pawl " is stretched out respectively from the centre of panel Yu baseplate width." pawl " on panel with Panel part length in one plane 2 centimetres, wide about 1.5 centimetres, " pawl " on base plate With base plate part length in one plane 2 centimetres, wide about 1.5 centimetres.The two " pawl " Front end, be intended to 77 degree turn round；Length after turning round is 1 centimetre." pawl " of panel Downwards, " pawl " of base plate is upwards.Two " pawl " sandwich one about grow 10 centimetres, interior The spring that footpath is 1.6 centimetres.The strength of spring be enough to strut panel and base plate.Base plate two On the edge of long limit part slightly before, a semicircular metal clamps to be respectively provided with, with respectively Block the air inlet pipe of air bag and the communicating pipe that air bag is middle with plenum chamber.The two is the highest by 1.3 Centimetre clamp another effect be exactly inflation pedal use during, when panel is stepped on by pin Withstand panel when obtaining the lowest, do not allow it press the most severe by air bag, it is to avoid the damage of air bag.The end The bottom surface of plate, i.e. near the part on ground, near four angles, be respectively welded one short " pin ".

Also manufacture an air bag with elastomeric material as similar bicycle tube.Air bag big Little by form air bag 3 rectangular blocks faces (two of which paste respectively below panel and Above base plate, do not expose) and the size in two gore faces determine.It is pasted onto face Below plate, two rectangular blocks faces with substrate are all grown 20 centimetres (24 131 1), i.e. 3 centimetres from hinge of rear portion, the two rectangular long limit, long limit front portion ratio panels and floor body Anterior edge indentation 1 centimetre.It is pasted onto below panel and two rectangular blocks faces of substrate Two equal ratio panels in long limit of wide 8 centimetres (10 111 1), i.e. the two rectangular blocks face and The long limit indentation of floor body 1 centimetre.Pedal near spring rectangular blocks face length about 9 centimetres, Wide 8 centimetres.The long length of side of two, the equilateral triangle on pedal both sides 20 centimetres, another limit is the longest 9 centimetres.

The outside in three faces that air bag exposes, needs four fastening wire of equidistant bonding.Fastening wire can be with straight The steel wire that footpath is 2 millimeters is made.A length of 56 centimetres (20+20+8+8) of fastening wire.Its work With being exactly during inflation pedal uses, do not allow air bag rubber outer wall too outwards blow-up, with There is enough air pressure that air is pressed into plenum chamber in ensureing air bag.

On four fastening wire, the outside in three faces i.e. exposed at air bag, also want entirety viscous The nylon cloth of one layer of resistance to torment of knot, to reinforce airbag wall and the position of firm four fastening wire.

On the edge of one triangle outer wall of air bag, a metal air inlet pipe to be installed.This enters The internal diameter of tracheae is about 1 centimetre, to ensure that air inlet is unobstructed.Air inlet pipe one end in air bag, Need to install a valve, air can only be entered can not be gone out.Air inlet pipe falls in the front portion of floor body On edge, the above of it to put a metal clamps, with the position of fixing air inlet pipe.

On the edge of another triangle outer wall of air bag, need to install a metal communicating pipe, i.e. The passage that air bag is middle with plenum chamber.The internal diameter of this communicating pipe also can be set to 1 centimetre.It In one end of plenum chamber, a valve to be installed, allow air can only enter plenum chamber and not Can go out from here.Fall communicating pipe on the anterior opposite side edge of floor body, above it Also a metal clamps is put, with the position of fixing communicating pipe.

In the front portion of inflation pallet body side, i.e. near communicating pipe, a cylinder need to be set The canister of body plenum chamber one by one.It need to be made with the most firm and solid metal.Its circular base Seat welds together with inflating the part being provided with communicating pipe clamp in pedal bottom plate.Its volume It is about 1/3rd of bag volume.One side bottom plenum chamber, need to connect jail communicating pipe.Even The end of siphunculus, i.e. communicating pipe are in the mouth of pipe in plenum chamber, need to install a valve, allow Pressurized air can only be entered and can not go out.It top or at other position, a little openning need to be opened, Closely connect a thicker appendix being difficult to be split up of outer wall, the end of appendix to install with Need the widget that Pneumatic article air inlet pipe hole matches, in case passing in and out two pipes in gas replenishment process Leak gas between hole.
