By adopting technique scheme, wherein relative second projection of the first projection is near insertion end and resistance surface, when swollen key does not have the support of inflatable component and rubber pneumatic bag time, by under the effect of reed, swollen key can overturn around the first projection, make resistance surface towards insertion end, in the process now inserted when rubber pneumatic bag, can not occur to conflict because of the end face of the end face of swollen key and rubber pneumatic bag and interfere and rubber pneumatic bag cannot be inserted; After rubber pneumatic bag inserts, by the elasticity of rubber pneumatic bag, reed is out of shape, thus swollen key is resetted, swollen bond energy is enough normally stretched.
The utility model is set to further: the described adapter plate held and comprise for fixing ball of conflicting, described resistance surface is positioned on adapter plate.
By adopting technique scheme, in the process energy manufactured, swollen key arranging hemispheric groove, again adapter plate is covered after ball is put into, thus ball is positioned, making the ball on swollen key easy for installation.
The utility model is set to further: described adapter plate is equipped with cambered surface in the both sides of axostylus axostyle axis.
By adopting technique scheme, cambered surface has the effect of guiding, avoids inflatable component and adapter plate end face to produce stuck phenomenon, can insert more smoothly in the process inserting inflatable component.

Detailed description of the invention
Referring to figs. 1 through Fig. 4, the utility model metal swollen key air-expanding shaft embodiment is described further.
A kind of metal swollen key 4 air-expanding shaft, comprise air-expanding shaft main body 1, air-expanding shaft main body 1 comprises hollow axostylus axostyle 2, be positioned at the inflatable component 3 of axostylus axostyle 2 and conflict with inflatable component 3 and extend the swollen key 4 of bar shaped of axostylus axostyle 2, swollen key 4 also comprises conflict end 41 and external part 42, conflict end 41 is provided with the reed 43 of conflicting with axostylus axostyle 2 inwall, conflict end 41 also comprises the circular arc resistance surface 48 of conflicting with inflatable component 3, described axostylus axostyle 2 is provided with the keyway 21 suitable with external part 42, described conflict end 41 is provided with some ball 44 grooves 411, be provided with in ball 44 groove 411 extend resistance surface 48 and with inflatable component 3 roll the ball 44(that coordinates wherein ball can be replaced by other rolling bodys, such as ball etc., the present embodiment preferably adopts ball 44).
Resistance surface 48 is arranged the ball 44 extended, when in the process that inflatable component 3 i.e. rubber pneumatic bag 31 inserts, friction of rolling is changed into by original cliding friction, the volume that wherein ball 44 extends accounts for 1/4th of ball 44 body cumulative volume, like this when rubber pneumatic bag 31 is in the process of inflation, by the distortion of rubber pneumatic bag 31, ball is embedded in rubber pneumatic bag 31, rubber pneumatic bag 31 closely can be conflicted with resistance surface 48, realize swollen key 4 to stretch smoothly, because air bag and resistance surface 48 fit tightly, therefore can not skid between air bag and swollen key 4, and maintain and replace rubber pneumatic bag 31 process in, rubber pneumatic bag 31 is not when inflating, the outside face of rubber pneumatic bag 31 can contact with the rolling body in resistance surface 48, and cooperation of rolling, the friction force reduction making insertion or extract, thus facilitate extraction and the insertion of rubber pneumatic bag 31, conveniently carry out maintenance to inflatable component 3 to change.
Described axostylus axostyle 2 comprises the insertion end for inserting inflatable component 3, the side that described swollen key 4 and keyway 21 cell wall are conflicted is provided with the first projection 46 and the second projection 47 of axostylus axostyle 2 axial distribution, described keyway 21 cell wall is respectively equipped with and two positioning grooves 22 of the first projection 46, second projection 47 to adaptation, described first projection 46 is near insertion end, and relative second projection 47 is near resistance surface 48, described keyway 21 is provided with the cambered surface overturn for swollen key 4.
Wherein relative second projection 47 of the first projection 46 is near insertion end and resistance surface 48, when swollen key 4 does not have the support of inflatable component 3 i.e. rubber pneumatic bag 31 time, under effect by reed 43, due between the first projection 46 and the second projection 47 and no longer same level, therefore swollen key 4 can overturn around the first projection 46, make resistance surface 48 towards insertion end, in the process now inserted when rubber pneumatic bag 31, can not occur to conflict because of the end face of the end face of swollen key 4 and rubber pneumatic bag 31 and interfere and rubber pneumatic bag 31 cannot be inserted; After rubber pneumatic bag 31 inserts, by the elasticity of rubber pneumatic bag 31, reed 43 is out of shape, thus swollen key 4 is resetted, swollen key 4 can normally be stretched.
Described conflict end 41 comprises the adapter plate 45 for fixing ball 44, and described resistance surface 48 is positioned on adapter plate 45.
In the process energy manufactured, swollen key 4 arranges hemispheric groove, again adapter plate 45 is covered after ball 44 is put into, thus ball 44 is positioned, make the ball 44 on swollen key 4 easy for installation.
In order to avoid inflatable component 3 and adapter plate 45 end face produce stuck phenomenon, can insert more smoothly in the process inserting inflatable component 3, adapter plate 45 is equipped with cambered surface in the both sides of axostylus axostyle 2 axis.
