Abstract

The utility model relates to an air pumping cylinder with double sleeves. The utility model comprises a left and a right sleeves which are sheathed on the same cylinder mouth; each interior of the left and the right sleeve is respectively provided with a left and a right pistons which are connected with a handle respectively through the left and the right draw rods; the cylinder mouth is provided with air pumping holes; a groove is arranged above the air pumping hole on one end where the cylinder nozzle and the sleeves are in sleeve joint, and an air blocking sheet matched with the groove is placed in the groove. As the air blocking sheet can not deviate from the groove when the air pumping is carried out or the pistons are pushed to reset to carry out the next air pumping, air in the sleeves can be prevented from reflowing into a vacuum bag packaging body to be carried out the air pumping when the piston is pushed back; as the air pumping cylinder is provided with double sleeves, the air pumping frequency can be reduced, the vacuum pumping can be carried out for the packaging body in a short period and the vacuum pumping efficiency can be greatly improved. Simultaneously, the utility model has the advantages of simple structure, large air pumping quantity, labor saving and convenient operation and is capable of quickly achieving the purpose of the vacuum pumping.

Description

A kind of bitubular pump bowl

[technical field]

The utility model relates to a kind of bitubular pump bowl.

[background technique]

I applied for once that an application number was 200420102469.8, the applying date is on December 7th, 2004, name is called the utility model patent of " a kind of pump bowl ", but this inflator has only a pump bowl, when bleeding to packing bodies such as vacuum bags, the distance of bleeding, rate of air sucked in required be little, bleed often, pumping efficiency is low, effort, needs the long time vacuumize to packing body, and volume is big, and packing is carried inconvenience.

[model utility content]

The purpose of this utility model is to overcome the deficiency of above-mentioned technical problem, provide a kind of simple in structure, bleed that distance is short, rate of air sucked in required is big, laborsaving, vacuumize the efficient height, detachable packing, packing bitubular pump bowl easy to carry.

The utility model is to adopt following technical proposals to realize: a kind of bitubular pump bowl, it is characterized in that including left and right sleeve, left and right jacket casing is on same tube mouth, in left and right sleeve, be provided with left and right piston, left and right piston is connected with handle by left and right pull bar respectively, on the tube mouth, have bleeder hole, above the bleeder hole of the end that tube mouth and left and right sleeve socket-connect, have a groove, a gas barrier plate that is complementary with this groove is set in groove.

Aforesaid a kind of bitubular pump bowl is characterized in that described gas barrier plate is the thin slice that soft material is made.

Aforesaid a kind of bitubular pump bowl is characterized in that an end of described gas barrier plate is fixed on left end in the mouth groove.

When the promotion piston reset is bled next time, gas barrier plate can not depart from groove, when pushing back, piston can prevent that like this air in the sleeve from flowing back in the vacuum bag packages body that will bleed again, again because pump bowl is two tubes, so more can be with the less number of times of bleeding, vacuumize to packing body in the short period of time, bigger raising the efficient that vacuumizes, simultaneously of the present utility model simple in structure, rate of air sucked in required is big, laborsaving, its mouth cooperates easily with the mouth of bleeding of packing body, easy to use like this, can reach the purpose that vacuumizes faster.

[embodiment]

Below in conjunction with accompanying drawing and embodiment model utility is described in further detail:

A kind of bitubular pump bowl, include left and right sleeve 1,2, left and right sleeve 1,2 is enclosed within on the same tube mouth 3, in left and right sleeve 1,2, be provided with left and right piston 4,5, left and right piston 4,5 is connected with handle 8 by left and right pull bar 6,7 respectively, bleeds with hold the piston 4,5 that spurs in the sleeve 1,2 on handle 8.

Left and right sleeve 1,2 is the cavity of a hollow, the one end is compressed into the cavity 9 of a mouth 3, left and right pull bar 6,7 inserts and is connected with piston 4,5 in the sleeve 1,2 from left and right sleeve 1,2 the other ends respectively, and the other end and the handle 8 of left and right pull bar 6,7 are fixed together.On tube mouth 3, have bleeder hole 10, be the air in the packing body such as extracting vacuum bag better, above the bleeder hole 10 of tube mouth 3 and an end of left and right sleeve 1,2 sockets, have a groove 11, the gas barrier plate 12 that placement one and this groove 11 are complementary in this groove 11, the thin slice that gas barrier plate 12 is made for soft material, its cross-section area is bigger than the bleeder hole 10 of tube mouth 3, can be enough to clog bleeder hole 10 like this, flows back in the packing body such as vacuum bag to prevent air in the left and right sleeve 1,2.One end of gas barrier plate 12 is fixed on the groove 11 interior left ends 15 of a mouth 3, when bleeding, under the positive air pressure effect in bleeder hole 10, gas barrier plate 12 produces the slit with the diapire 13 of tube mouth 3 after gas barrier plate 12 middle parts and the other end generation deformation, so air was bled in this slit enters left and right sleeve 1,2 afterwards in the bleeder hole 10, gas barrier plate 12 1 ends are fixed on the groove 11 interior left ends 15 of a mouth 3 again, stay in the groove 11 of a mouth 3 so still can guarantee gas barrier plate 12 after back gas barrier plate 12 the other ends of bleeding rise; Then promote left and right piston 4,5 resets when bleeding next time, gas barrier plate 12 produces and resets in the groove 11 under the residual air effect in left and right sleeve 1,2, thereby bottle up bleeder hole 10, in order to avoid the air in the left and right sleeve 1,2 flows back in the packing body again, like this can be with less number of times, vacuumize to packing body in the short period of time, improve the efficient of bleeding.It is longer that tube is used for the length of the valve mouth 14 that is connected with the mouth of bleeding of packing body on the mouth 3, valve mouth 14 is fully injected in the valves and do not leak gas.

The utility model in use, fully inject the valve mouth on the tube mouth 3 14 in the mouth of bleeding of packing body, being used for pull handle 8 bleeds, gas barrier plate 12 produces deformation under the positive air pressure effect of bleeder hole 10, the slit of air between the diapire 13 of gas barrier plate 12 and tube mouth 3 enters a left side like this, right sleeve 1, in 2 and be drawn out of, promote handle 8 then and make piston 4,5 reset, on a left side, right sleeve 1, gas barrier plate 12 resets to and clogs bleeder hole 10 in the groove 11 under the residual air effect in 2, prevent a left side, right sleeve 1, residual air in 2 flows back in the packing body again, with less number of times, the efficient air in the packing body such as vacuum bag of finding time faster.
