Description

Simple and convenient type prevents backward flow balloon setting bracing piece

Technical Field

The utility model relates to a device for the balloon, concretely relates to can assist the bracing piece of stereotyping effect to aerifing the back balloon, can also prevent that the phenomenon of backflowing from producing and simple structure.

Background

The balloon can be used to decorate, amusement etc. is common article among people's daily life, the pattern of balloon, the colour is various, but the shape after ordinary balloon is aerifyd mostly uses circularly as leading, and the difficult fixing of ordinary balloon is other shapes, utility model patent application No. 201921585125.8 discloses a balloon setting bracing piece promptly, cooperate this bracing piece to the balloon when the balloon of blowing, can blow out the balloon of other shapes, but use the balloon that the device blew out, still must use the rope, fastener such as rubber band ties up the balloon air inlet, and the device can't prevent the emergence of balloon reflux condition, still need inflate it again after taking place to lose heart, influence its normal decoration, amusement result of use, and complex operation. The utility model discloses a utility model patent application No. 201922325964.4 discloses a can satisfy the balloon device that just can prevent the backflow phenomenon to the balloon setting simultaneously, but the device needs to have special air-lock valve to realize preventing the production of balloon gas leakage phenomenon to air-lock valve structure itself is not simple, needs the manpower and the equipment of special mould and equipment, and is still not simple and convenient enough. In view of the above, there is a need for a balloon shaping device that can assist in shaping a balloon while preventing backflow, and that is simple in structure.

SUMMERY OF THE UTILITY MODEL

The utility model aims at providing a refluence balloon setting bracing piece is prevented to simple and convenient type, this bracing piece can assist the balloon setting when the balloon blows, can also prevent the emergence of the condition of backflowing to the device simple structure, it is convenient to use, and the cost is lower, does benefit to and uses widely.

In order to achieve the purpose, the utility model adopts the following technical proposal:

the utility model provides a simple and convenient type prevents balloon setting bracing piece that backflows, includes the body of rod upper end is equipped with first location portion, and the lower extreme of the body of rod is equipped with second location portion, is equipped with the inlet port at body of rod lower extreme, is equipped with the venthole on the body of rod the venthole is equipped with elastic sealing device outward, elastic sealing device can seal the venthole under gaseous pressure.

Preferably, the lower end of the rod body gradually expands to form a cylindrical air inlet channel, the port of the air inlet channel forms the air inlet hole, and the air outlet hole is formed in the side wall of the air inlet channel.

Preferably, an annular mounting groove is formed in the outer side of the air inlet channel, the air outlet hole is formed in the annular mounting groove, and the elastic sealing device is arranged in the annular mounting groove.

Preferably, the elastic sealing device is an annular soft rubber ring.

Preferably, the second positioning portion is an annular groove arranged along an outer circle of the cylindrical air inlet channel.

In the technical scheme, the shaping effect after the balloon is blown can be assisted, the balloon is enabled to be inflated to form an apple shape, the backflow phenomenon of the balloon can be prevented, the apple shape of the balloon can be kept for a long time, the using effect is enhanced, in addition, the backflow preventing structure of the product is simple, the production and manufacturing of the product are facilitated, the cost is low, and the popularization and the use are facilitated.

Drawings

FIG. 1 is a schematic view of the present invention in use;

fig. 2 is an explosion diagram of the present invention.

Detailed Description

The present invention will be further explained with reference to the accompanying drawings:

as shown in fig. 1 and 2, the simple anti-backflow balloon shaping support rod comprises a rod body 1, wherein a first positioning part 2 is left at the upper end of the rod body 1, and the first positioning part 2 is formed by an annular groove formed between an upper annular convex edge and a lower annular convex edge which are arranged side by side. The lower extreme of the body of rod 1 expands gradually and forms cylindric inlet channel 3, and inlet channel 3's port forms inlet port 4, leaves annular mounting groove 5 on inlet channel 3's lateral wall, leaves venthole 6 on mounting groove, just is located the inherent elastic sealing device 7 of annular mounting groove 5 cover outside the venthole, and is preferred, and elastic sealing device 7 is the soft rubber ring of annular. And a second positioning part 8 is reserved at the lower end part of the outer side wall of the cylindrical air inlet channel 3 and below the annular mounting groove, and the second positioning part 8 can be the same as the first positioning part in structure and is formed by an annular groove between an upper annular convex edge and a lower annular convex edge.

When using above-mentioned device, at first stretch into the balloon 10 inside with the bracing piece is whole, make the upper end of the body of rod 1 be located the top position of balloon 10, the lower extreme of the body of rod 1 is located the upper portion position of balloon air inlet, then use elasticity fastener such as rubber band outside the balloon to be in the same place first recess 2 and second recess 8 are fixed about balloon and the bracing piece, then aim at bracing piece inlet port 4 positions with aerating device and aerify to the balloon in, aerify the back, because the distance between balloon top and the balloon air inlet is fixed, and after other positions of balloon aerify the inflation, the balloon forms similar apple shape promptly, can strengthen the novelty and the interest of balloon. When gas enters the interior of the balloon from the outside, the gas enters the air inlet cylindrical air inlet channel 3 through the air inlet hole 4, blows the elastic sealing device 7 outside the air outlet hole 6 and then enters the interior of the balloon, and the balloon is inflated. After the balloon is inflated, the elastic fastening device 7 is tightly attached to the annular mounting groove 5 and seals the air outlet 6 under the action of the air pressure in the balloon, so that the effect of preventing the air in the balloon from flowing back and leaking is achieved, the air inlet does not need to be fastened after the balloon is inflated, and the apple shape of the balloon can be kept for a long time.

The embodiment is only an illustration of the concept and implementation of the present invention, and is not a limitation, and the technical solution without substantial transformation is still within the protection scope under the concept of the present invention.
