Abstract

The utility model relates to a reusable self-closing balloon, which is composed of a balloon bag (5), an internal threaded pipe (1), an external threaded pipe (2), a membrane valve plate (6) and a fixing ring (7), wherein the upper periphery of the internal threaded pipe (1) is provided with an annular groove (3), and the side wall of the upper port of the external threaded pipe (2) is provided with an exhaust notch (4); and the length of the external threaded pipe (2) is larger than the length of the internal threaded pipe (1). The external threaded pipe (2) and the internal threaded pipe (1) are in screw-thread match and sheathing, and the upper ports are flush. The membrane valve plate (6) is installed and fixed at the side wall of the upper end of the internal threaded pipe (1), so that the valve plate is just covered on the upper port. The annular groove (3) of the internal threaded pipe (1) is sheathed in the bag open of the balloon bag (5), and the fixing ring (7) is annularly sheathed in the annular groove (3) to tighten the bag open of the balloon bag (5) on the outer wall of the internal threaded pipe (1). With simple structure, the balloon is automatically sealed under the idea situation of swell. After pressure relief, the balloon bag is still intact and is recycled. The using and the storage are convenient, and the reusable self-closing balloon is beneficial to protecting environment and reducing using cost.

Description

Can reuse self-closing's balloon

Technical field

The utility model belongs to balloon, is specifically related to a kind of self-seal type balloon that reuses.

Background technology

Balloon is a kind of celebrating amusement article that people are familiar with, and particularly in celebration or festivals or holidays, people like increasing happy atmosphere with its dress up celebration place or domestic environment.The tradition balloon normally with sacculus with the inflation of mouth or inflator after, tie up with cotton rope again, often be not because of under-inflation lacks aesthetic feeling, exactly because of inflating excessive explosion, and spheroid is easy to leak big stop-tendency scape.In the prior art, also have the self-seal type balloon to come out, but because of its structure complexity cause cost higher, and sacculus can only disposablely use, and can't reuse.Therefore, no matter be the self-seal type balloon of traditional balloon or prior art, all be unfavorable for environmental protection, and waste is big, use inconvenient.

Summary of the invention

At the above-mentioned defective that prior art exists, propose a kind of self-closing's of recycling balloon of meter, make it simple in structure, use and preserve conveniently, help protecting environment and reduce use cost.

Technical solution adopted in the utility model is as follows.

A kind of self-closing's balloon that reuses comprises sacculus, it is characterized in that:

1) it also has riffled tube, male-pipe, film valve block and retainer ring;

2) periphery, top of riffled tube offers annular groove, and the upper port sidewall of male-pipe offers the exhaust notch;

3) length of male-pipe is greater than the length of riffled tube, and male-pipe is nested with riffled tube screw thread coupling and upper port is flushed, and the upper end sidewall that the film valve block is fixed on riffled tube makes valve block cover upper port just;

4) annular groove of riffled tube is inserted in the capsule mouth of sacculus, the retainer ring ring set in annular groove with the tight-lipped hoop of the capsule of sacculus on the riffled tube outer wall.

The reused self-closing balloon of said structure preferably is equipped with connecting ring on said riffled tube outer wall, so that a plurality of balloons are linked together.

The reused self-closing balloon of said structure, said riffled tube and male-pipe preferably adopt light material, for example plastic tube, plastic-aluminum pipe, aluminium-alloy pipe etc.

The utility model can reuse self-closing's balloon, inflate from male-pipe in use, air-flow backs down the film valve block and enters in the sacculus (the film valve block plays the check valve effect), air pressure in the sacculus increases along with the increase of gas flow, when becomeing greater to perfect condition gradually, balloon stops inflation, at this moment the gas pressure in the balloon impels film valve block pressurized and the upper port of internal and external screw thread pipe is closed automatically, causes the balloon voltage stabilizing not leaked in the perfect condition of bulging and becomes flat; If recovery balloon, only need inside turn male-pipe to make its upper port exceed the upper port of riffled tube, thereby back down the film valve block, gas is discharged from male-pipe through the exhaust notch rapidly under gas pressure, sacculus returns to the contraction state before the inflation intactly, the keeping collection; Again with the outside turn of male-pipe, its upper port is flushed with the upper port of riffled tube when treating that next celebration or festivals or holidays need, realize recycling from the male-pipe inflation again.

The utility model can reuse self-closing's balloon; simple in structure; balloon can be air tight from movable sealing under the perfect condition of bulging; and sacculus remains intact harmless after the release; can repeatedly reuse; promptly or sacculus utilizes repeatedly because of aging breakage also only need more renew capsule again, use and preserve conveniently, help protecting environment and reduce use cost.

Description of drawings

Accompanying drawing is the cross-sectional plane structural representation that the utility model can reuse an example of self-closing's balloon.

In the drawings, 1-riffled tube, 2-male-pipe, 3-annular groove, 4-exhaust notch, 5-sacculus, 6-film valve block, 7-retainer ring, 8-connecting ring.

The specific embodiment

Further specify the concrete structure that the utility model can reuse self-closing's balloon below in conjunction with example figure.

A kind of self-closing's balloon that reuses comprises sacculus 5, it is characterized in that:

1) it also has riffled tube 1, male-pipe 2, film valve block 6 and retainer ring 7;

2) periphery, top of riffled tube 1 offers annular groove 3, and the upper port sidewall of male-pipe 2 offers exhaust notch 4;

3) length of male-pipe 2 is greater than the length of riffled tube 1, and male-pipe 2 is nested with riffled tube 1 screw thread coupling and upper port is flushed, and the upper end sidewall that film valve block 6 is fixed on riffled tube 1 makes valve block cover upper port just;

4) annular groove 3 of riffled tube 1 is inserted in the capsule mouth of sacculus 5, retainer ring 7 ring sets in annular groove 3 with the tight-lipped hoop of the capsule of sacculus 5 on riffled tube 1 outer wall.

The reused self-closing balloon of this example product is equipped with connecting ring 8 at riffled tube 1 outer wall; What its riffled tube 1 and male-pipe 2 adopted is the plastic-aluminum pipe.
