Abstract

The utility model relates to a pedal pump which is provided with an air box which is inserted with an air outlet valve and an air inlet valve, wherein a cover body is covered on the air box and is provided with a perforation; the free ends of the air outlet valve and the air inlet valve outwards extend from the point of the perforation, and the internal wall surface of the cover body can be respectively and mutually clamped and bunted with the air outlet valve and the air inlet valve. When the internal air pressure of articles which need to be inflated reaches to a certain degree, since the internal wall surfaces of the air outlet valve and the cover body are mutually clamped and bunted, the air outlet valve and the air box can not mutually disengage, and accordingly, the integrity of the pedal pump can be kept.

Description

Foot pump

Technical field

The utility model is a kind of foot pump, provides a kind of foot pump that the article of desire inflation can be inflated.

Background technique

The gas-filled type article, for example: plastics swimming pool, water wing, air cushion or bed etc. have extensively been used by people, the advantage of gas-filled type article is to be easy to carry and to collect, because this type of article only need in being used in gas to be packed into, make it be expanded to certain volume and just can use, only need gas is released, can be easy to carry and collect when finishing using, and the gas-filled type article all can use an inflator so that gas is filled in it, and modal inflator is exactly a foot pump.

Existing foot pump, please cooperate with reference to shown in Figure 4, it has the bellows 30 of a hollow, on bellows 30, be respectively equipped with two perforation (not shown), be installed with a ring body 301 with hole respectively in perforation place, place, hole in ring body 301 is inserted with a suction valve 31 and gas outlet valve 32 respectively, suction valve 31 is to be inserted in respectively in the hole of ring body 301 with an end of gas outlet valve 32, suction valve 31 is all check valve body with gas outlet valve 32, it is made that present existing ring body 301 is commonly the softer rubber of material, and bellows 30, it is made that suction valve 31 and gas outlet valve 32 are commonly the harder plastic material of material.

When using, one end and the gas outlet valve 32 of one pneumatic tube 33 are interconnected, the other end of pneumatic tube 33 and the article of desire inflation are being interconnected, for example: the plastics swimming life-buoy, plastics swimming pool or bed or the like, when bellows 30 are compressed, gas in the bellows 30 will via gas outlet valve 32 and pneumatic tube 33 enter article to be inflated in, and the gas that is positioned at bellows 30 outsides can be inhaled into previous compressed bellows 30 inside via suction valve 31, make bellows 30 return to not compressed shape, so bellows 30 are compressed repeatedly and resile, and finish inflation procedure until the inner gassy of article.

Yet this inflation procedure still has its shortcoming to exist, behind the inner gassy of article, its inside can have certain air pressure, and the user still continues compression bellows 30 in unwitting situation, the compressed gas of bellows 30 inside is the inside that can't charge into article at this moment, and the air pressure that compressed gas produced can force gas outlet valve 32 and bellows 30 to break away from mutually, if gas outlet valve 32 and bellows 30 through repeatedly break away from turn back to after, the aperture of ring body 301 will be out of shape by an end of gas outlet valve 32, so gas outlet valve 32 just can't and bellows 30 between interfix, will cause and must change a brand-new foot pump, and the puzzlement that makes existing foot pump truly have it to use.

The model utility content

This creator is because existing foot pump the time has the situation that gas outlet valve and bellows break away from mutually in inflation, so redesign a kind of foot pump with lid, by fastening mutually between cover body face and the gas outlet valve, make gas outlet valve and ring body to break away from by the bellows place, the integrity that keeps foot pump by this is its practical novel purpose.

In order to reach aforesaid model utility purpose, technological means of the present utility model is to provide a kind of foot pump, its tool one bellows, the periphery wall of bellows is formed with some flangings, perisporium in bellows is provided with perforation, be installed with a ring body with hole in perforation place, in the hole of ring body, be inserted with gas outlet valve and suction valve respectively;

One lid, it is covered on the top of bellows, and lid is provided with perforation, and the free end of gas outlet valve and suction valve is stretched out by perforation place, the cover body face fastens mutually with gas outlet valve and suction valve respectively, the prominent tab that can fix mutually with the groove of bellows that is formed with of the root edge of lid.

When using, one end and the gas outlet valve of one pneumatic tube are interconnected, the end in addition of pneumatic tube interconnects with the article of desire inflation, and compression bellows, gas in the bellows will enter article inside via gas outlet valve and pneumatic tube, perseveration like this, until the article gassy, behind the article gassy, its inside has certain air pressure, this air pressure can stop the air pressure in the bellows to enter in the article, and the gas in the bellows continues be compressed, and this air pressure can force gas outlet valve to break away from ring body, but is to fasten mutually between gas outlet valve and the cover body face, so gas outlet valve can't so can keep the integrity of foot pump by breaking away from the bellows.

Embodiment

The utility model is a kind of foot pump, please cooperate with reference to Figure 1 and Figure 2, it has bellows 10, the periphery wall of bellows 10 is formed with some flangings 11, be respectively equipped with perforation 15 in the periphery wall of bellows 10 and with respect to the position on top, be installed with a ring body 16 with hole respectively in perforation place, the place, hole of ring body 16 is inserted with a suction valve 12 and gas outlet valve 13 respectively, suction valve 12 is the holes that are positioned at ring body 16 with an end of gas outlet valve 13, suction valve 12 is all check valve body with gas outlet valve 13, and suction valve 12 is formed with larger-size shoulder 121 respectively with the middle section of gas outlet valve 13,131;

One lid 20, please cooperate referring to figs. 1 to shown in 3, it is covered on the top of bellows 10, lid 20 is provided with two perforation 21,22, the internal face of lid 20 respectively with the shoulder 121 of suction valve 12 and gas outlet valve 13,131 fasten mutually, and aforesaid shoulder 121,131 size is greater than perforation 21,22 aperture, and the free end of suction valve 12 and gas outlet valve 13 can be by perforation 21,22 places are outwards outstanding, and in the root edge place of lid 20 the prominent tabs 23 that can fix mutually that are formed with the flanging 11 of bellows 10, by the fixing of tab 23 and flanging 11 and bore a hole 21,22 respectively with the fixing of suction valve 12 and gas outlet valve 13, and lid 20 and bellows 10 are interfixed.

When reality is used, please cooperate again with reference to shown in Figure 2, one end and the gas outlet valve 13 of one pneumatic tube 14 are interconnected, the end in addition of pneumatic tube 14 interconnects with the article of desire inflation, when bellows 10 are compressed, the air of bellows 10 inside can enter article inside via gas outlet valve 13 and pneumatic tube 14, can enter bellows 10 inside via suction valve 12 and be positioned at bellows 10 air outside, and bellows 10 are resiled, so bellows 10 are compressed repeatedly and resile, just can be with the inner gassy of article.

After the article gas inside reaches certain air pressure, if the user continues compression bellows 10, compressed gas in the bellows 10 is owing to can't enter article inside, therefore the air pressure that this gas produced can force gas outlet valve 13 to break away from the hole of ring body 16, but the shoulder of gas outlet valve 13 131 is to fasten mutually with the internal face of lid 20, so gas outlet valve 13 is subjected to stopping from lid 20, therefore can't break away from by ring body 16 places, the bore deformation that causes ring body 16 so can avoid repeatedly turning back to gas outlet valve 13 can make foot pump keep its integrity by this.
