Detailed Description

The present invention will be described in further detail with reference to specific examples, but the embodiments of the present invention are not limited thereto.

Referring to fig. 1, fig. 1 is a schematic structural diagram of a balloon firecracker machine according to an embodiment of the present invention. This balloon firecrackers machine includes:

the plate cover comprises a piece of covering plate 1 which is made of elastic materials and is provided with a hole in the middle, a pull rope 2, a plate cover 3 which is made of sealed hard materials, a bottom plate 4 which is made of hard materials and is provided with a hole in the middle, and a plurality of sharp objects 5 which are arranged on the surface of one side of the bottom plate 4 and have sharp positions facing the piece of covering plate 1.

Wherein the sheet cover 3 is used to connect the top covering sheet 1 and the outer edge of the bottom sheet 4 to form a barrel-shaped space; the tension rope 2 is located in the barrel-shaped space, one end of the tension rope is connected with the inner edge of the covering piece 1, the other end of the tension rope is connected with the inner side of the plate cover 3, and the tension rope 2 is used for stretching the covering piece 1 to the inner side of the barrel-shaped space to be sunken.

When the balloon firecracker machine is in a use state, an air ball string is placed on one side, close to the covering plate 1, in the barrel-shaped space, the pulling force end of the air ball string penetrates out of the barrel-shaped space through the hole in the bottom plate 4, when the pulling force end is pulled forcibly, the air ball string moves from one side of the covering plate 1 to one side of the bottom plate 4 in the barrel-shaped space based on a similar one-way valve structure until the balloon is pierced by the sharp object 5 and then makes a sound.

When the balloon firecracker machine is not in use, the shielding layer 1 and the bottom plate 4 are respectively used as a bottom surface and a top surface, so that the balloon firecracker machine is used as a supporting tool.

The following is a detailed description of the various components:

the sheet mask 1 is made of an elastic material having an easy stretch property, and the material may include rubber, an elastomer material, and the like. The aperture of the sheet 1 is sized to allow smooth passage of the string of balloons therethrough. The shape of the holes can be round, rectangular and the like. The outer edge of the sheet mask 1 is sealingly connected to the sheet mask 3, which may be by means of adhesive or the like.

The tension rope 2 is made of elastic material and is in a stretching state, and the shading sheet 1 is pulled to the inner side of the barrel-shaped space to form a recess under the action of the tension. The tensile cord 2 may be connected to the sheet covering sheet 1 and the sheet cover 3 by adhesion or by using other auxiliary means such as a hook.

The plate cover 3 is made of a sealed hard material and can be connected with the bottom plate 4 by bonding or welding, or the plate cover 3 and the bottom plate 4 can be integrally formed.

Except for the middle hole, the rest part of the bottom plate 4 is also made of sealed hard materials. The shape of the hole can be round, rectangular and the like, the size of the hole can be smaller than that of the hole of the shielding sheet 1, and the broken balloon can be allowed to pass through the hole.

It should be noted that no matter what connection method is adopted among the top covering sheet 1, the plate cover 3 and the bottom plate 4, the formed barrel-shaped space is sealed except for the holes on the top covering sheet 1 and the bottom plate 4. It will be appreciated that, since the top covering sheet 1 and the bottom sheet 4 may take the shape of a circle, a rectangle, etc., the barrel-shaped space may be in the shape of a barrel, a rectangular barrel, a trapezoidal barrel, etc., and fig. 1 is illustrated as a barrel shape for simplicity. For example, in an alternative embodiment, the top shielding sheet 1 and the bottom sheet 4 may be circular with the same radius.

The plurality of sharp objects 5 are arranged on the surface of the bottom plate 4 facing to one side of the top shielding plate 1, and the sharp parts face to the top shielding plate 1. The sharp object 5 can be in a shape with a sharp top, such as a needle shape, a cone shape and the like, and can be made of hard materials, such as plastics, metals and the like. The arrangement mode can be uniform distribution or irregular distribution, the number can be set according to the requirement, for example, the holes surrounding the bottom plate 4 can be distributed in a divergent shape uniformly until the bottom plate 4 is covered, and the like.

The using state and the non-using state of the balloon firecracker machine are explained as follows:

before the balloon firecracker machine is used, the side wall of the balloon firecracker machine can be grounded, namely the plate cover 3 is in contact with the ground, and in order to avoid displacement of the balloon firecracker machine, the balloon firecracker machine can be fixed in a hand-held mode and the like.

Connecting the balloons into a string through a rope to form a balloon string; then, the rope end of the balloon string without the balloon is used as a pulling end, the pulling end is pulled to slightly pull the balloon string into the barrel-shaped space from the outer side of the top covering sheet 1, and the pulling end penetrates out of the hole of the bottom plate 4, but the balloon is always kept close to one side of the top covering sheet 1 in the barrel-shaped space and does not contact with the sharp object 5.

It will be appreciated that the inwardly recessed screening sheet 1 is angled with respect to a vertical plane, i.e. the screening sheet 1 is inclined with respect to the vertical plane. When the balloon is pulled according to the above direction, the balloon will naturally move along the surface of the inward-concave and inclined covering sheet 1 under the action of the pulling force and is concentrated outside the hole in the middle of the covering sheet 1, and in addition, the materials for manufacturing the covering sheet 1 and the balloon are both easy-to-stretch materials, and the balloon can be conveniently extruded into the barrel-shaped space from the hole in the middle of the covering sheet 1. When the balloon inside the barrel is imagined, it is more likely that the balloon will move along the surface of the inclined cover sheet 1 under the combined action of the outward thrust and the large inward spring force applied thereto by the cover sheet 1. The stretched tension rope 2, the inward-sunken sunshade piece 1 and the plate cover 3 form a one-way valve-like structure, and the balloon can be effectively prevented from overflowing outwards.

When the firecracker sound needs to be sent out, the pulling end is pulled by force, so that the balloon is strung in the barrel-shaped space and moves from one side of the covering piece 1 to one side of the bottom plate 4, and the moving balloon is punctured when contacting with a sharp object 5 after passing through a one-way valve structure consisting of the inwards-concave covering piece 1, the stretched pulling rope 2 and the plate cover 3, and the sound capable of replacing the firecracker is sent out. Wherein, the pulling speed can be set according to the requirement of firecracker sound.

It can be understood that under the combined action of the inward-recessed top shading sheet 1, the sheet cover 3 and the balloon at the back, the outward flying amount of balloon fragments can be effectively reduced, the balloon fragments can be basically accumulated in the barrel-shaped space, and the balloon fragments can be cleaned outwards through the hole of the top shading sheet 1, so that the field cleaning can be conveniently realized. Meanwhile, the sharp object is not directly exposed in the barrel-shaped space, so that potential safety hazards can be reduced.

When the balloon firecracker machine is not used, the shielding layer 1 and the bottom plate 4 can be respectively used as a bottom surface and a top surface, so that the balloon firecracker machine can be used as a supporting tool. Referring to fig. 2, fig. 2 is a schematic structural diagram of a balloon firecracker machine provided in an embodiment of the utility model as a supporting tool, specifically taking a barrel shape as an example. The supporting means can be, for example, a stool or a device for supporting the rest of the object, etc. Therefore, the balloon firecracker machine has a practical function in a non-use state, and the utilization rate can be improved.

According to the balloon firecracker machine provided by the utility model, the sharp object is wrapped in the barrel-shaped space and is in a non-exposed state, so that the safety can be improved; when the balloon breaking device is used, broken balloon fragments can be concentrated in the barrel-shaped space, so that the cleaning difficulty can be reduced. And when the balloon firecracker machine is not in use, the balloon firecracker machine can be used as a supporting tool, so that the function singleness can be avoided, and the utilization rate in daily life is improved.

In order to further improve the cleaning efficiency of the broken balloon fragments, the side wall of the plate cover 3 can be provided with a window structure, and in a use state, the window is closed to realize a sealing effect; when cleaning, the window can be opened, which is convenient for cleaning the balloon fragments in the barrel-shaped space, therefore, compared with the cleaning from the hole of the top covering sheet 1 alone, the cleaning efficiency can be improved.

Of course, the bottom plate 4 may also be designed to be detachable from the plate cover 3, and when in use, the two are installed and closed to realize sealing, and even a sealing ring or the like may be further used to realize sealing effect; when cleaning, the two are separated again.

Alternatively, a combination of the two alternatives can be used, and this is reasonable.

As mentioned above, the barrel-shaped space may be in the shape of a barrel, a rectangular barrel, a trapezoidal barrel, or the like. When the plate cover 3 is partially in contact with the ground, the balloon firecracker machine is easy to roll, operation is not facilitated, and manual fixation or temporary finding of foreign objects for fixation is inconvenient. In order to avoid displacement and facilitate operation, in an alternative embodiment, please refer to fig. 3 to 5, fig. 3 is a schematic structural diagram of another balloon firecracker machine provided by an embodiment of the utility model; FIG. 4 is a rear perspective view of another alternative balloon firecracker machine provided by embodiments of the present invention; fig. 5 is a front perspective view of another balloon firecracker machine according to the embodiment of the utility model. As shown in fig. 3 to 5, the balloon firecracker machine may further include:

two first brackets 6 and respective second brackets 7; wherein each bracket is a cuboid; the two first supports 6 are attached to the surface of the bottom plate 4 outside the barrel-shaped space along the length direction, are arranged in parallel and expose complete holes on the bottom plate 4 in a spaced area; each first bracket 6 is vertically installed with a corresponding second bracket 7; the two first brackets 6 and the corresponding second brackets 7 are used for fixing the position of the balloon firecracker machine when the plate cover 3 is contacted with the ground. It will be appreciated that, in use, the two second brackets 7 may also be pressed by foot or weight to further secure the balloon firecracker machine.

In an alternative embodiment, the two first supports 6 and the respective second supports 7 are both made of hard material.

In the present invention, in order to improve the service life and the stability of the balloon firecracker machine, the hard material comprises metal, such as aluminum alloy and the like.

It should be noted that fig. 3 to 5 are only an example and illustrate the positions of two first supports 6 and the corresponding second supports 7 and the positional relationship therebetween, for example, in fig. 3, it is assumed that the corresponding plane of the base plate 4 is an XY plane, and the two second supports 7 are arranged along the-Z axis. However, in another alternative mode, please refer to fig. 6, and fig. 6 is another schematic position diagram of two second brackets in another balloon firecracker machine provided by the utility model. Fig. 6 is a view from the bottom plate 4 in the direction of the top cover sheet 1, and for the sake of simplicity, only the bottom plate 4, two first brackets 6 and respectively corresponding second brackets 7 are shown, the respective coordinate axes being indicated in the upper right corner. It can be seen that in fig. 6, the second bracket 7 is not along the length-Z direction of the barrel space, but along the ± Y direction. But still arranged in a perpendicular position to the corresponding first bracket 6.

The first bracket 6 is fixed on the bottom plate 4 by means of bonding or any one of the existing locking devices, and can be detached, for example, by means of a screw and nut assembly.

Each first bracket 6 and the corresponding second bracket 7 are vertically fixed through assembly tools and can be detached. In an alternative embodiment, each of the first brackets 6 and the corresponding second bracket 7 are fixed by a screw-nut assembly.

In an alternative embodiment, the plate cover 3 is provided with two mounting holes near the bottom plate 4. Accordingly, for each first support 6, the first support 6 is clamped and fixed to the base plate 4 by a flat-nose-like clamp 8. One end of the flat-nose pliers 8 is connected to one of the mounting holes, and the other end of the flat-nose pliers is connected to one side surface of the first support 6, which is parallel to and far away from the bottom plate 4.

Fig. 3 to 5 illustrate a flat-nose pliers-like type 8, but as described above, the manner in which the first bracket 6 is fixed to the base plate 4 is not limited to this.

Regarding the flat-nose pliers 8, in an alternative embodiment, please refer to fig. 7 and 8, fig. 7 is a schematic structural diagram of a similar flat-nose pliers provided by an embodiment of the present invention; FIG. 8 is a partial schematic view of a flat-nose pliers-like structure provided in accordance with an embodiment of the present invention; the flat-nose pliers 8 may comprise:

A first screw hole is formed in the fixed caliper body 11, so that the screw 17 can move along the first screw hole; the movable pliers body 10 is provided with a second screw hole; the first jaw plate 9 is fixed on the movable jaw body 10, and the second jaw plate 12 is fixed on the fixed jaw body 11; the sliding groove 14 is arranged on the movable caliper body 10, and the guide rail 13 is arranged on the fixed caliper body 11, so that the movable caliper body 10 can move along the guide rail 13.

During the user state, if first support 6 is not connected to on the bottom plate 4, will pass through the mounting hole of sheet metal covering 3 with second jaw board 12 earlier, block on bottom plate 4, later clockwise rotation nut 15, because of nut 15 can not be through first screw, will drive movable vice body 10 together, to fixed vice body 11 motion, reduce the distance between first jaw board 9 and the second jaw board 12, realize the fixed to first support 6 and bottom plate 4. If the first bracket 6 is not connected with the second bracket 7, the second bracket 7 is connected with the first bracket 6 through a screw and nut assembly.

When the balloon firecracker machine is not in use, the two first brackets 6 and the corresponding second brackets 7 are removed, and the covering piece 1 and the bottom plate 4 are respectively used as a bottom surface and a top surface, so that the balloon firecracker machine is used as a supporting tool.

Specifically, after the use is accomplished, anticlockwise rotation nut 15 will drive the activity body of pincers 10 and keep away from fixed body of pincers 11 because of card 16 can't pass through first screw, increases the distance between first jaw 9 and the second jaw 12, cancels the fixed between first support 6 and the bottom plate 4, realizes the dismantlement to first support 6. And then the screw and nut for connecting the first bracket 6 and the second bracket 7 are dismounted, so that the second bracket 7 can be dismounted. And then the balloon firecracker machine is rotated to the state shown in the figure 9, and the balloon firecracker machine can be used as a supporting tool. Fig. 9 is a schematic structural diagram of another balloon firecracker machine provided in the embodiment of the utility model as a supporting tool.

It can be seen that the two first brackets 6 and the corresponding second brackets 7 can fix the position of the plate cover 3 of the balloon firecracker machine when the plate cover is in contact with the ground for use, so that the plate cover does not shake or displace, and the balloon firecracker machine is convenient to use. Meanwhile, the two first brackets 6 and the corresponding second brackets 7 are convenient to mount and dismount, so that the using state and the non-using state of the balloon firecracker machine can be switched rapidly.
