Detailed Description
The following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present utility model, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.
In order that the above-recited objects, features and advantages of the present utility model will become more readily apparent, a more particular description of the utility model will be rendered by reference to the appended drawings and appended detailed description.
It is to be appreciated that the paper tube filled with the effect drug and the fuze is folded into a circle shape, so that the color chrysanthemum fireworks can be obtained, and the manufacturing cost and the market selling price of the color chrysanthemum fireworks are low; in addition, when the color chrysanthemum fireworks are set off, the color flames can be emitted while rotating, so that a pattern of full-open chrysanthemum or a pattern of a rotating top is formed, and the color chrysanthemum fireworks have higher ornamental value; based on the characteristics of high ornamental value and low selling price of the color chrysanthemum fireworks, the color chrysanthemum fireworks are popular among the masses; however, due to the limitation of the production process of the color chrysanthemum fireworks, the color chrysanthemum fireworks fuze is clung to the color chrysanthemum fireworks after being bent, so that a user is required to buckle the color chrysanthemum fireworks fuze before the color chrysanthemum fireworks are set off, the color chrysanthemum fireworks can be ignited, obviously, the ignition step of the color chrysanthemum fireworks is complicated, and the experience of the user when the color chrysanthemum fireworks are set off is reduced.
To solve this problem, as shown in fig. 1 or fig. 2, the present utility model connects a plurality of color chrysanthemum fireworks 3 to one lead 12; therefore, when the user sets off the color chrysanthemum fireworks, the fuze of the color chrysanthemum fireworks does not need to be laboriously picked out/scratched out one by one, after the lead 12 is ignited, the color chrysanthemum fireworks 3 can be sequentially ignited along with the combustion of the lead 12, so that the complexity of setting off the color chrysanthemum fireworks is simplified, and the experience of setting off the color chrysanthemum fireworks by the user is improved.
However, it should be noted that, in the prior art, as in the connection portion 9Y of the patent document CN236563, the whip is used to twist the lead wire of the single small firework together with the main lead wire, so as to realize the connection between the small firework and the main lead wire 12; however, if this connection method is used for connecting the color chrysanthemum fireworks and the leads 12, before the color chrysanthemum fireworks fuse is gathered and twisted/tied on the leads 12, the producer needs to pick out/scratch the color chrysanthemum fireworks fuse one by one, which obviously increases the complexity of connecting the color chrysanthemum fireworks to the leads 12 and reduces the production efficiency of the product formed by the color chrysanthemum fireworks and the leads 12.
In order to solve the problem, the method for connecting the small fireworks to the main lead 12 by the traditional modes of gathering twisting/tying wires and the like is omitted, only the steps of arranging a plurality of color chrysanthemum fireworks 3 in a row/line, enabling the fuzes of the color chrysanthemum fireworks 3 to face to the same direction (for example, arranging the color chrysanthemum fireworks 3 in a line, enabling the fuzes to face upwards), then, the lead 12 is lapped on each color chrysanthemum fireworks fuze, and enough adhesive is dripped into the contact area of the lead 12 and the color chrysanthemum fireworks fuze, and the color chrysanthemum fireworks fuze and the lead 12 are connected into a whole through the adhesive, so that the steps of manually picking the color chrysanthemum fireworks lead 12 by production personnel, gathering twisting/tying wires and the like are omitted, and the production efficiency of products formed by the color chrysanthemum fireworks and the lead 12 is greatly improved.
Moreover, when the adhesive is dropped, if the lead 12 and the fuze of the color chrysanthemum fireworks 3 are directly lapped together, the adhesive is wrapped on the outer sides of the fuze of the color chrysanthemum fireworks and the lead 12, the color chrysanthemum fireworks 3 can be smoothly ignited when the lead 12 burns, but if part of the adhesive is dropped between the fuze of the color chrysanthemum fireworks and the lead 12, the thickness of the adhesive between the fuze of the color chrysanthemum fireworks and the lead 12 is larger, and the adopted adhesive is of a type with poor combustibility, so that the lead 12 can not be smoothly ignited when the lead 12 burns, and the situation that part of the color chrysanthemum fireworks are not set off can occur; in order to avoid the occurrence of the situation, the utility model selects the adhesive with both the bonding performance and the combustibility to ensure that the color chrysanthemum fireworks 3 can be smoothly ignited and prevent the situation that the lead wires 12 are burnt completely and a plurality of color chrysanthemum fireworks 3 are not ignited.
The adhesive in the utility model can be gunpowder adhesive, and the gunpowder adhesive is specifically: glue mixed with gunpowder; but not limited to gunpowder glue, other adhesives meeting the bonding requirement and the flammability requirement of the color chrysanthemum fireworks can be used.
However, when the adhesive is gunpowder adhesive, as a certain amount of gunpowder is mixed in the adhesive, compared with the pure adhesive, the adhesive is slightly lower, so that part of the color chrysanthemum fireworks are easy to fall off from the lead 12 in the transportation process, and thus, the color chrysanthemum fireworks cannot be ignited by igniting the lead 12, and the fallen color chrysanthemum fireworks are inconvenient to ignite again.
The utility model has the advantages that the two sides of the color chrysanthemum fireworks are respectively provided with the limiting parts 2, one side of the limiting parts 2, which is close to the color chrysanthemum fireworks bending pipe 5, is provided with the arc-shaped coaming 6 which is attached to the bending pipe 5, the chamber 7 is formed by the bending pipe 5, the rotating disk 4, the arc-shaped coaming 6 and the limiting parts 2, and the chamber 7 is filled with the adhesive; before the limiting piece 2 is not arranged to form the cavity 7, the dripping area of the adhesive is only in the contact area of the color chrysanthemum firework fuse and the lead 12, the excessive adhesive can slide along the color chrysanthemum firework, the adhesive amount is less, and the fixation of the color chrysanthemum firework fuse is poor; after the limiting piece 2 is arranged to form the cavity 7, the adhesive amount capable of dripping is greatly increased in the cavity 7, so that the color chrysanthemum fireworks cannot fall off from the lead 12 in the transportation process, and the effect of ensuring that the color chrysanthemum fireworks are convenient to ignite can be continuously maintained.
Furthermore, if the limiting pieces 2 are independently arranged and clamped at two sides of each color chrysanthemum firework in sequence, the actual workload is large, and the production efficiency of products formed by the color chrysanthemum firework and the fuze is also reduced; in order to avoid the problem, as shown in fig. 1 or fig. 2, a plurality of limiting pieces 2 for fixing the color chrysanthemum fireworks are arranged on a substrate 1, the color chrysanthemum fireworks are clamped between the adjacent limiting pieces 2, and when a cavity 7 is formed by the limiting pieces 2 and an arc-shaped coaming 6 through the integrated design of the limiting pieces 2 and the substrate 1, the color chrysanthemum fireworks are clamped between the two limiting pieces 2, so that the problem that the production efficiency of products formed by the color chrysanthemum fireworks and a lead 12 is reduced due to the fact that the limiting pieces 2 are clamped on two sides of the color chrysanthemum fireworks one by one is avoided.
As shown in fig. 1-3, the color chrysanthemum firework comprises two rotating discs 4 arranged in parallel, and a bending tube 5 positioned between the two rotating discs 4. When the substrate 1 is provided with a plurality of limiting pieces 2, the end face of any rotating disk 4 is contacted with the substrate 1, fuzes extend out of the tail end of the bent pipe 5, each fuze is connected to the same lead 12, one side, close to the bent pipe 5, of the limiting piece 2 is connected with an arc-shaped coaming 6, and the arc-shaped coaming 6 is attached to the outer wall of the bent pipe 5; at this time, the rotary disk 4, the arc-shaped coaming 6, the stopper 2, and the bending tube 5 are formed with a chamber 7, and the chamber 7 is filled with an adhesive for connecting the lead 12 and the fuse as a whole.
Moreover, the lead 12 is wound on the substrate 1, and the bayonet 11 for clamping/penetrating the lead 12 is arranged on the substrate 1, so that the color chrysanthemum fireworks can be fixed on the substrate 1, the shaking degree of the color chrysanthemum fireworks in the transportation process is reduced, meanwhile, the problem that the lead 12 is broken and the color chrysanthemum fireworks fall off from the lead 12 in the subsequent disassembly process due to the fact that the substrate 1 is not arranged, and only the structures of the lead 12, the color chrysanthemum fireworks, the limiting piece 2, the arc coaming 6 and the like are arranged in the transportation process.
It should be noted that, the winding manner of the lead 12 is not unique, and is changed according to the pattern/text that the color chrysanthemum firework is intended to enclose, and the lead 12 can be wound around the substrate 1 in a meandering manner, so that the color chrysanthemum firework forms a winding sleeping dragon, and the color chrysanthemum firework can also form an n shape or an m shape.
In order to avoid the problem that partial areas of the leads 12 cannot burn when the leads 12 burn due to breakage of the leads 12 in the transportation process or incorrect selection of the leads 12 in the production process, and the color chrysanthemum fireworks in the area cannot be ignited, as shown in fig. 1 or fig. 2, the distance between the adjacent leads 12 is smaller than the burning area of a single lead 12 in the utility model, so that even if the problem that a part of one lead 12 cannot burn, the color chrysanthemum fireworks in the area can be ignited by the adjacent lead 12, and smooth ignition of the color chrysanthemum fireworks is ensured.
Furthermore, the utility model can also adopt to arrange a standby lead on the substrate 1, and each color chrysanthemum firework lead 12 is connected through the standby lead; when the color chrysanthemum fireworks are set off, the lead 12 and the standby lead can be ignited simultaneously, and at the moment, even if the local area of the lead 12 is broken, all the color chrysanthemum fireworks cannot be ignited, and the standby lead can also ignite all the color chrysanthemum fireworks, so that the smooth setting off of the color chrysanthemum fireworks is ensured.
In addition, in order to further avoid the problem that the color chrysanthemum fireworks fall off from the lead 12 in the transportation process, a connecting part 9 is arranged between the substrate 1 and the color chrysanthemum fireworks, and the color chrysanthemum fireworks are fixed on the substrate 1 through the connecting part 9; in order to ensure that the color chrysanthemum fireworks can smoothly slide out from the base plate 1 after being ignited (the sliding out means that the color chrysanthemum fireworks leave the base plate 1 under the action of self-rotation force after being ignited), the connecting part 9 is arranged to be the connecting part 9 which is easy to break, so that the connecting part 9 can break due to the fact that the rotation force of the color chrysanthemum fireworks is not born, and the color chrysanthemum fireworks can smoothly slide out.
The connecting part 9 can be a connecting rod which is easy to break or a glue layer with a melting point lower than the burning temperature of the color chrysanthemum firework fuse and the lead 12.
In order to further improve the capability of the color chrysanthemum fireworks to slide out of the substrate 1, the substrate 1 can be bent into a plurality of inclined planes 8, and the color chrysanthemum fireworks are uniformly distributed on the inclined planes 8, so that the color chrysanthemum fireworks can be held by the self-rotation force when sliding out, and the self-gravity force component on the inclined planes 8 is obtained to push the color chrysanthemum fireworks and the product formed by the leads 12 to have higher ornamental value.
Meanwhile, the rotary disc 4 is provided with the rotary shaft 10 at one side far away from the bent pipe 5, and the rotary shaft 10 is positioned in the central area of the rotary disc 4, so that the color chrysanthemum fireworks can be enabled to have stronger rotary cruising ability and the ornamental value of the color chrysanthemum fireworks is improved no matter which end face of the rotary disc 4 is contacted with the base plate 1, and even if the color chrysanthemum fireworks can fall down when 'slip out' from the inclined plane 8 on the base plate 1, the color chrysanthemum fireworks can still be contacted with the ground through the rotary shaft 10.
However, the stop member 2 in the present utility model is a "double edged sword": the cavity 7 filled with the adhesive is formed in an auxiliary mode, the connection firmness degree of the color chrysanthemum firework fuze and the lead 12 is improved, and meanwhile rotation of the color chrysanthemum firework is limited, so that the color chrysanthemum firework is difficult to slide out of the substrate 1; to improve the problem, the length of the limiting piece 2 is set to be not larger than the radius of the color chrysanthemum fireworks, and the arc-shaped coaming 6 is arranged at the end of the limiting piece 2, so that the filling amount of the adhesive in the cavity 7 is improved to the greatest extent, and the color chrysanthemum fireworks fuse is connected with the lead 12 firmly enough.
In addition, the decorative paper or the packing box is sleeved outside the base plate 1, and the decorative paper or the packing box is made of a moisture-proof material, so that on one hand, the color chrysanthemum fireworks and the leads 12 can be prevented from being wetted in the transportation process, and the color chrysanthemum fireworks can be ensured to be smoothly set off; on the other hand, the product formed by the color chrysanthemum fireworks and the lead wires 12 can be set off in rainy days.
In addition, the centers of the color chrysanthemum firework fuse, the lead 12 and the standby lead are cotton threads wrapped with gunpowder layers, two cotton thread layers are sequentially wrapped outside the gunpowder layers from inside to outside, and the cotton thread layers are sequentially wrapped with sealing layers and isolating layers; the isolating layer can prevent cracks from occurring on the outer surface of the lead 12 when the lead 12 is bent, so that gunpowder in the lead 12 is burned or knocked over, and meanwhile, the isolating layer is obtained by carrying out plastic full-package cladding on the sealing layer and the inner structure of the sealing layer through a plastic extruder.
The principles and embodiments of the present utility model have been described in detail with reference to specific examples, which are provided to facilitate understanding of the method and core ideas of the present utility model; also, it is within the scope of the present utility model to be modified by those of ordinary skill in the art in light of the present teachings.
