Technical Field

[0001] The present invention belongs to the field of fireworks, and specifically relates to a fireworks rack, a combination of fireworks racks, and a method for setting off fireworks. Background Art

[0002] China is a major producer of fireworks and firecrackers and is the world's largest producer and exporter of fireworks and firecrackers. The fireworks industry has become a pillar of economic development in some regions of China. At the same time, the setting off of fireworks is also an indispensable item in various festivals, and the brilliant and colorful sparks can enhance the lively and joyous atmosphere. Traditional fireworks generally produce sound and light effects through gunpowder detonation to achieve visual and auditory effects. With the development of the fireworks industry, the types of fireworks are increasing, and many fireworks have also added other additional effects. For example, some fireworks can use the reaction force generated by the combustion and ejection of gunpowder to move or rotate the fireworks launcher, and some fireworks can play music during the setting off. However, the pursuit of the setting off effect of fireworks still requires the fireworks industry to constantly bring forth new ideas and create more novel viewing effects. Summary of the Invention

[0003] The present invention provides a fireworks rack that can automatically tilt after being set off, increasing the fun of setting off fireworks.

[0004] The content of the present invention includes a fireworks rack, which comprises a fireworks seat, a control lead, and an elastic member. One end of the elastic member is connected to the bottom of the fireworks seat. The control lead keeps the elastic member in a compressed state, and after the control lead burns, the elastic member resets and pushes the fireworks seat to tilt.

[0005] Further, the elastic member is a torsion spring. The control lead is wound around the torsion arms of the torsion spring to bring the two torsion arms of the torsion spring together. After the control lead burns, one torsion arm of the torsion spring abuts against the bottom of the fireworks seat, and the other torsion arm unfolds and abuts against the supporting surface on which the fireworks seat is placed, causing the fireworks seat to tilt.

[0006] Further, an installation hole is provided at the bottom of the fireworks seat, and one torsion arm of the torsion spring passes through the installation hole.

[0007] Further, a groove is provided at the bottom of the fireworks seat, the elastic member is a compression spring disposed in the groove, and one end of the control lead closes the notch of the groove to compress the compression spring in the groove.

[0008] Further, an installation groove and a first control lead groove that communicate with each other are provided at the bottom of the fireworks seat. The elastic member is disposed in the installation groove and is located on one side of the bottom of the fireworks seat, and one end of the control lead enters the installation groove from the first control lead groove.

[0009] Further, a fireworks cartridge installation tube is vertically provided on the fireworks seat.

[0010] Further, it further includes a top plate. Both ends of the firework cartridge installation tube are respectively connected to the firework base and the top plate. The top plate is provided with a through hole communicating with the firework cartridge installation tube, a firework cartridge lead groove communicating with the through hole, and a second control lead groove communicating with the firework cartridge lead groove. The other end of the control lead enters the firework cartridge lead groove from the second control lead groove.

[0011] A firework rack combination includes a connecting lead and a plurality of the above-mentioned firework racks. The plurality of firework racks are arranged linearly, and the tipping direction of the firework racks is perpendicular to the arrangement direction. The connecting lead connects the plurality of firework racks in sequence, and the control lead on each firework rack is connected to the connecting lead.

[0012] Further, the connecting lead includes a plurality of detachable lead segments, and the lead segments are magnetically connected to each other.

[0013] A method for setting off fireworks of the above-mentioned firework rack combination. The firework rack is equipped with a firework cartridge, and a plurality of firework cartridges are connected to the connecting lead. The method includes the following steps:

[0014] S1. Ignite the connecting lead;

[0015] S2. The connecting lead ignites the firework cartridges and the control leads in a plurality of firework racks in sequence;

[0016] S3. A plurality of control leads release the elastic members simultaneously or in sequence, so that a plurality of firework racks tip over simultaneously or in sequence.

[0017] The beneficial effects of the present invention:

[0018] By arranging an elastic member compressed by a lead between the bottom of the firework rack and the supporting surface on which the firework rack is placed, after the control lead burns, the elastic force generated by the reset of the elastic member is used to make the firework rack fall to one side on the supporting surface, realizing the effect of the firework rack tipping over. The firework rack of the present invention does not need to use gunpowder explosion to make the firework base tip over, and the effect is safe and controllable, increasing the interest of setting off fireworks;

[0019] Through the combination of a plurality of firework racks, the linearly arranged fireworks tip over after being set off, realizing a visual effect similar to knocking down the winning hand in mahjong, greatly increasing the interest and ornamental value of the fireworks; in the firework rack combination, the firework racks are connected by connecting leads, and the tipping of adjacent two firework racks does not affect each other. The firework racks can tip over simultaneously or in sequence. By setting the connecting lead and the control lead, the setting-off time and the tipping time are controlled, realizing various setting-off and tipping sequences, and meeting the requirements of more firework setting-off scenarios.

[0020] Different from the anti-tipping settings of most fireworks on the market, the present invention creatively sets the tipping effect of the firework rack, and can control the tipping timing of the firework rack by controlling the burning time of the control lead, so that the firework rack tips over after the firework setting-off is over, ensuring safety.

[0038] As shown in the Figures 1 - 10 accompanying drawings, the present invention includes a fireworks rack, which includes a fireworks base 1, a control lead 2, and an elastic member 3. One end of the elastic member 3 is connected to the bottom of the fireworks base 1. The control lead 2 keeps the elastic member 3 in a compressed state. After the control lead 2 burns, the elastic member 3 resets and pushes the fireworks base 1 to tilt.

[0039] In a preferred embodiment, the elastic member 3 is a torsion spring, including a connecting torsion arm 31 and a free torsion arm 32. The connecting torsion arm 31 is connected to the bottom of the firework base 1, and the control lead 2 is wound around the torsion arm of the torsion spring to make the connecting torsion arm 31 and the free torsion arm 32 of the torsion spring converge. Specifically, after the control lead 2 bypasses the second torsion arm, it can be fixed to the firework base 1 by means such as adhesion, knotting or nailing, so that the free torsion arm 32 converges towards the firework base 1; after the control lead 2 burns, the connecting torsion arm 31 abuts against the bottom of the firework base 1, and the free torsion arm 32 unfolds and abuts against the supporting surface on which the firework base 1 is placed, destroying the horizontal placement state of the firework base 1 and causing the firework base 1 to tilt. In the present invention, the elastic member 3 is a torsion spring. Compared with other types of elastic members 3, controlling the control lead 2 to wind around the torsion arm to achieve compression has higher operability.

[0040] In a preferred embodiment, an installation hole 13 is provided at the bottom of the firework base 1, and the connecting torsion arm 31 passes through the installation hole 13 and is connected to the bottom of the firework base 1, ensuring that the connecting torsion arm 31 continues to abut against the bottom of the firework base 1 after the torsion spring unfolds. The elastic member 3 can be connected to the bottom of the firework base 1 without additional processing, which is convenient for installation and at the same time facilitates the winding operation of the control lead 2.

[0041] In a second preferred embodiment, the connecting torsion arm 31 is fixed to the bottom of the firework base 1, and after the control lead 2 burns, the connecting torsion arm 31 abuts against the bottom of the firework base 1.

[0042] In a second preferred embodiment, a groove is provided at the bottom of the firework base 1, and the elastic member 3 is a compression spring arranged in the groove. One end of the control lead 2 closes the groove opening to compress the compression spring in the groove. After the control lead 2 burns, the compression spring rebounds, and both ends respectively abut against the bottom of the firework base 1 and the supporting surface on which the firework base 1 is placed.

[0043] In a preferred embodiment, an installation groove 11 and a first control lead groove 12 that communicate with each other are provided at the bottom of the firework base 1. One end of the control lead 2 enters the installation groove 11 from the first control lead groove 12; the elastic member 3 is arranged in the installation groove 11 and is located on one side of the bottom of the firework base 1 to ensure the tilting direction of the firework base 1. The control lead 2 and the elastic member 3 are arranged in the groove, which does not affect the contact between the bottom of the firework base 1 and the supporting surface on which the firework base 1 is placed, ensuring that the firework base 1 can be placed stably and avoiding safety accidents during the firework display process.

[0044] Specifically, taking the torsion spring as an example, as shown in the appendix Figures 6 - 10As shown, in order to facilitate processing, place stably and better control the tipping direction, a rectangular firework holder 1 is used. A rectangular mounting groove 11 is provided at the bottom of the firework holder 1. The width of the rectangular mounting groove 11 is greater than or equal to the width of the elastic member 3. A horizontal plate 14 is provided in the mounting groove 11 near the bottom edge of the firework holder 1. The two ends of the horizontal plate 14 are connected to the two side walls of the mounting groove 11 and are parallel to the bottom of the mounting groove 11. The distance between the horizontal plate 14 and the bottom of the mounting groove 11 is greater than or equal to the diameter of the connecting torsion arm 31 of the elastic member 3. A square mounting hole 13 is formed between the horizontal plate 14 and the mounting groove 11. The connecting torsion arm 31 of the elastic member 3 passes through the mounting hole 13 and passes to the bottom edge of the firework holder 1. The free torsion arm 32 can move freely on the outside of the horizontal plate 14. One end of the first control lead groove 12 is vertically connected to the mounting groove 11, and the other end passes through the edge of the base of the firework holder 1. One end of the control lead 2 enters the mounting groove 11 from the first control lead groove 12. As shown in the attached Figure 7 and 8 As shown, when the elastic member 3 is in a compressed state, the control lead 2 radially bypasses the outer side of the free torsion arm 32, then goes around the connecting torsion arm 31, and finally passes between the connecting torsion arm 31 and the bottom of the mounting groove 11. The connecting torsion arm 31 applies elastic force to the control lead 2 toward the bottom of the mounting groove 11, so that the control lead 2 is stuck and fixed between the connecting torsion arm 31 and the bottom of the mounting groove 11, thereby maintaining the compressed state of the elastic member 3. Preferably, the distance between the cross plate 14 and the bottom of the mounting groove 11 is equal to the diameter of the connecting torsion arm 31 of the elastic member 3, and the connecting torsion arm 31 can be just stuck in the mounting hole 13, ensuring that the elastic member 3 can also better abut against the firework holder 1 after being unfolded. In order to compress the elastic member 3, the control lead 2 is in a taut state. After the control fuse 2 burns, the connecting torsion arm 31 is still in contact with the firework holder 1, and the free torsion arm 32 is away from the horizontal plate 14 and in contact with the supporting surface on which the firework holder 1 is placed. When the free torsion arm 32 abuts against the supporting surface and cannot continue to expand relative to the firework holder 1, the elastic force of the elastic member 3 causes the connecting torsion arm 31 to lift one side of the firework holder 1, and the balance of the firework holder 1 is destroyed, and finally the firework holder 1 topples onto the supporting surface.

[0045] In the present invention, the control lead 2 is fixed by the above-mentioned winding connection method, which does not require knotting to add extra operations, nor does it require additional components such as adhesives or nails to increase costs. The operation is simple, the cost is low, and the production efficiency is high. The installation hole 13 is a square hole, which has at least the following three advantages: the square installation hole 13 can be formed by directly adding a cross plate 14 on the basis of the installation groove 11, which is convenient for processing and beneficial to production; the width of the installation hole 13 is the same as the width of the installation groove 11, and there is a surplus in the width of the installation hole 13 relative to the diameter of the connecting torsion arm 31, which facilitates the connecting torsion arm 31 to pass through the installation hole 13. At the same time, because the distance between the cross plate 14 and the bottom of the installation groove 11 has no surplus relative to the diameter of the connecting torsion arm 31, the connecting torsion arm 31 can better abut against the fireworks base 1 and can also clamp and fix the control lead 2; the width of the installation groove 11 has no surplus relative to the elastic member 3. When the control lead 2 bypasses the connecting torsion arm 31, it can also be stuck between the connecting torsion arm 31 and the groove wall of the installation groove 11, adding an additional layer of fixation for the control lead 2 and making the device more stable.

[0046] It should be noted that the fireworks base 1, the installation groove 11, and the installation hole 13 can also adopt other shapes; in addition to setting the installation hole 13 by setting the cross plate 14, the installation hole 13 can also be set by other means; the installation groove 11 and the first control lead groove 12 at the bottom of the fireworks base 1 can also be set in other extending directions; the control lead 2 can be wound in other ways to make the elastic member 3 in a compressed state.

[0047] In a preferred embodiment, a fireworks cartridge installation tube 4 is vertically arranged on the fireworks base 1 for installing the fireworks cartridge. It should be noted that a fireworks rack can include multiple fireworks cartridge installation tubes 4.

[0048] In a preferred embodiment, a top plate 5 is further included. The two ends of the fireworks cartridge installation tube 4 are respectively connected to the fireworks base 1 and the top plate 5. The top plate 5 is provided with a through hole 51 communicating with the fireworks cartridge installation tube 4, a fireworks cartridge lead groove 52 communicating with the through hole 51, and a second control lead groove 53 communicating with the fireworks cartridge lead groove 52. The other end of the control lead 2 enters the fireworks cartridge lead groove 52 from the second control lead groove 53. In this embodiment, a rectangular frame structure is formed between the fireworks base 1 and the top plate 5, which can be packaged outside the fireworks rack, such as in the form of a mahjong block, to increase the interest and ornamental value.

[0049] Specifically, as shown in the attached Figure 2As shown in the figure, the firework cartridge installation tube 4 includes a first tube body 41 and a second tube body 42 which are detachably connected. One end of the first tube body 41 is fixedly connected to the firework base 1, and one end of the second tube body 42 is fixedly connected to the top plate 5. The first tube body 41 and the second tube body 42 are nested and connected. The diameter of the first tube body 41 is larger than that of the second tube body 42. One end of the second tube body 42 away from the top plate 5 is closed and used for placing the firework cartridge. The firework base 1 and the first tube body 41 can be integrally formed, and the top plate 5 and the second tube body 42 can be integrally formed, which is convenient for production, installation and use. In actual use, the top plate 5 and the second tube body 42 may be damaged by the firework discharge. The detachable design can replace the damaged top plate 5 and the second tube body 42, and the firework base 1 and the first tube body 41 can be reused, saving costs. Cooperating with the elastic member 3 connected to the bottom of the firework base 1 in a threading manner, a new elastic member can be replaced after the elastic member 3 is elastically worn, ensuring the dumping effect during repeated use.

[0050] It should be noted that the firework cartridge installation tube 4 can be set as an integral type, and the three components of the firework base 1, the firework cartridge installation tube 4 and the top plate 5 can also be integrally formed.

[0051] Specifically, as shown in the appendix Figure 8 As shown in the figure, the firework cartridge lead groove 52 on the top plate 5 is communicated with the second control lead groove 53. To save leads, the notch of the second control lead groove 53 on the top plate 5 is aligned with the notch of the first control lead groove 12 on the firework base 1. The first control lead groove 12 at the bottom of the firework base 1 is communicated with the installation groove 11. Among them, the laying route of the control lead 2: in the firework cartridge lead groove 52, one end is connected to the connecting lead 6 or the lead of the firework cartridge, starting from the connection point in the firework cartridge lead groove 52, entering the second control lead groove 53, after passing through the second control lead groove 53, leading out of the top plate 5 from the notch of the second control lead groove 53, extending vertically downward, leading into the bottom of the firework base 1 from the notch of the first control lead groove 12, passing through the first control lead groove 12 and leading into the installation groove 11, and finally the other end is wound around the elastic member 3.

[0052] In a sub-optimal embodiment, the firework cartridge installation tube 4 is arranged in a settling manner in the firework base 1. The top of the firework base 1 is provided with a firework cartridge lead groove 52 communicating with the firework cartridge installation tube 4 and a second control lead groove 53 communicating with the firework cartridge lead groove 52. The other end of the control lead 2 enters the firework cartridge lead groove 52 from the second control lead groove 53.

[0053] As shown in the appendix Figure 11As shown in the figure, the present invention includes a fireworks rack combination, which includes a connecting lead wire 6 and several of the above-mentioned fireworks racks. The several fireworks racks are arranged linearly, and the tipping direction of the fireworks racks is perpendicular to the arrangement direction. The connecting lead wire 6 connects several fireworks racks in sequence, and the control lead wire 2 on each fireworks rack is connected to the connecting lead wire 6. In this embodiment, the fireworks racks are connected by the connecting lead wire 6 in the fireworks cartridge lead wire groove 52. The tipping of adjacent two fireworks racks does not affect each other. Through the setting of the connecting lead wire 6 and the control lead wire 2, simultaneous tipping or sequential tipping can be achieved; during transportation, because they are connected by the connecting lead wire 6, the finished product of the fireworks rack combination can be folded during transportation, and the fireworks racks therein can be stacked, or the connecting lead wire 6 can be arranged after transporting the fireworks racks to the firing site to obtain the fireworks rack combination, which is convenient for transportation.

[0054] In a preferred embodiment, the connecting lead wire 6 includes several detachably connected lead wire segments. One lead wire segment is arranged in the fireworks cartridge lead wire groove 52 of each fireworks rack. When using the fireworks rack combination, the lead wire segments connecting adjacent two fireworks racks are connected to form a lead wire combustion path. The connecting lead wire 6 in this embodiment adopts a segmented design. During transportation, the lead wire segments are disconnected, and the fireworks racks can be stacked flexibly, improving the stacking efficiency and saving transportation space. When in use, each fireworks rack comes with a lead wire segment of the connecting lead wire 6. The fireworks rack combination does not need to arrange the lead wire additionally. After stacking the fireworks racks, connecting the lead wire segments on each fireworks rack can form a combustion path, which is convenient and fast and easy to use. Preferably, the lead wire segments are connected by a magnetic attraction method. Magnetic attraction elements are arranged at both ends of each lead wire segment. When in use, the adjacent ends of the lead wire segments of adjacent two fireworks racks are magnetically attracted to form a combustion path, and the operation is simple and fast.

[0055] In a preferred embodiment, connection components are arranged on the lateral sides of the fireworks racks. The fireworks racks can be directly connected through the connection components, such as magnetic attraction connection, assembly connection, screw connection or bonding, etc. When the fireworks racks in the fireworks rack combination are set to tip simultaneously, the tipping of one fireworks rack drives the tipping of the adjacent fireworks rack, ensuring the synchronization of the tipping time among several fireworks racks, thereby ensuring the tipping effect.

[0056] In a preferred embodiment, the fireworks racks are connected by magnetic attraction. For example, magnets with different magnetic poles are arranged on the lateral sides of the fireworks racks. When stacking the fireworks racks, the magnetic poles of adjacent two fireworks racks are different and attract each other to achieve connection. In this embodiment, the fireworks rack combination is convenient and fast to disassemble and install, and can be disassembled and stacked to save space during transportation.

[0057] In a preferred embodiment, the fireworks racks are assembled and connected. For example, grooves and protrusions perpendicular to the support surface are provided on the lateral sides of the fireworks racks. The grooves and protrusions on both sides of each fireworks rack can be fitted and connected to each other. When stacking, the protrusions of the fireworks racks are fitted into the adjacent fireworks grooves. When the fireworks racks tilt, a force that causes the adjacent fireworks racks to tilt is applied to ensure synchronous tilting. During transportation, they can be disassembled and stacked to save space.

[0058] In a preferred embodiment, the fireworks racks are connected by screwing. For example, threaded holes are provided on the lateral sides of the fireworks racks. When stacking, the threaded holes of two adjacent fireworks racks are aligned and fixedly connected by bolts. In this embodiment, the connection between the fireworks racks is firm, ensuring the tilting effect.

[0059] In a preferred embodiment, the fireworks racks are bonded. For example, bonding components are provided on the lateral sides of the fireworks racks and directly bonded during use; alternatively, when stacking the fireworks racks, an adhesive is applied to the sides of the fireworks racks to bond two adjacent fireworks racks. This embodiment has low processing costs and is convenient for production.

[0060] It should be noted that the "lateral direction" referred to in the embodiments of the present invention refers to the direction perpendicular to the tilting direction of the fireworks rack.

[0061] In a preferred embodiment, the fireworks rack is in an overall rectangular frame structure. A number of fireworks racks are arranged in a straight line in close contact with each other in sequence. The tilting directions of a number of fireworks racks are perpendicular to the straight-line arrangement direction and the same; a packaging paper with a mahjong pattern is provided on the periphery of the fireworks rack. When the fireworks rack tilts, a visual effect of toppling and winning in mahjong is achieved, greatly increasing the fun.

[0062] The present invention includes a method for setting off fireworks with a combination of fireworks racks. The fireworks cartridge installation tube 4 of the fireworks rack is filled with fireworks cartridges, and a number of fireworks cartridges are connected to the connecting lead 6. The method includes the following steps:

[0063] S1. Ignite the connecting lead 6;

[0064] S2. The connecting lead 6 sequentially ignites the fireworks cartridges and the control leads 2 in a number of fireworks racks;

[0065] S3. A number of control leads 2 simultaneously or sequentially release the elastic member 3, causing a number of fireworks racks to tilt simultaneously or sequentially.

[0066] In a preferred embodiment, the setting-off time and the tilting time are controlled through the connecting lead 6 and the control lead 2. The fireworks cartridges in a number of fireworks racks are set off simultaneously. After all the setting-offs are completed, a number of fireworks racks tilt simultaneously.

[0067] In a preferred embodiment, the firing time and the dumping time are controlled by connecting the lead wire 6 and the control lead wire 2. The fireworks cartridges of several fireworks racks are fired simultaneously, and after all the firings are completed, the several fireworks racks are dumped in sequence.

[0068] In a preferred embodiment, the firing time and the dumping time are controlled by connecting the lead wire 6 and the control lead wire 2. The fireworks cartridges of several fireworks racks are fired in sequence, and after all the firings are completed, the several fireworks racks are dumped simultaneously.

[0069] In a preferred embodiment, the firing time and the dumping time are controlled by connecting the lead wire 6 and the control lead wire 2. The fireworks cartridges of several fireworks racks are fired in sequence, and after all the firings are completed, the several fireworks racks are dumped in sequence.

[0070] In a preferred embodiment, the firing time and the dumping time are controlled by connecting the lead wire 6 and the control lead wire 2. After one fireworks rack is fired and dumped, the next fireworks rack connected to this fireworks rack is then fired and dumped.

[0071] By controlling the firing time and the dumping time through the connecting lead wire 6 and the control lead wire 2, the fireworks racks and the combination of fireworks racks in the present invention can achieve rich and variable visual effects and can meet the requirements of more fireworks firing scenarios.
