Description

Cartridge with lift-off effect for fireworks

Technical Field

The utility model relates to a firework component, in particular to an effect cartridge for loading a firework powder to be launched and lifted off.

Background

In the prior art, many fireworks use effect cartridges loaded with gunpowder to be launched and lifted off. In one application scenario, a plastic barrel 101 on a moon travel firework as shown in fig. 1 is provided with a round head end 102 with an orientation function at the top end, and a firework powder is filled into the inner cavity of the plastic barrel from an open bottom end 103 and a lead wire is installed. The device has the defects that when the inner cavity of the plastic cylinder 101 is filled with the firework powder, a large amount of plastic cylinders 101 are bundled into a cylinder cake form, the cylinder cake form is pressed down by a die rod group driven by an oil press and is inserted into the bottom end 103 to fill the firework powder, the round head end 102 is abutted with the base plate downwards, the firework effect is not affected by the compressed powder if the pressure is insufficient during the pressing, and especially the firework powder at the round head end 102 is difficult to compress; if the pressure is increased, the deformation or breakage of the rounded tip 102 is likely to affect the guiding function. Therefore, the round end 102 of the existing effect cartridge is difficult to realize guiding, the effect cartridge can roll and incline when the empty effect cartridge is launched due to the lack of guiding, and the product is difficult to reduce in size only by virtue of the stabilizing rod 104 fixed on the outer side of the plastic cartridge 101. In practice, the flat-ended plastic cylinder 105 shown in fig. 2 is used instead of the plastic cylinder with the round end so as to compress the powder.

Detailed Description

Example 1: referring to fig. 3-4, one specific configuration of the present utility model is reflected. The firework lift-off effect cartridge consists of a cylindrical barrel 1 and a conical end head 2 which are in split structures, wherein a top end opening 8 of the cylindrical barrel 1 is connected with a bottom end opening 6 of the conical end head 2 through a detachable connection structure. In the example, the top end of the cylindrical barrel 1 is provided with a plugging part 3, the inner diameter of the inner cavity of the plugging part 3 is consistent with the inner diameter of the inner cavity of the cylindrical barrel 1, the outer diameter of the plugging part 3 is smaller than the outer diameter of the cylindrical barrel 1, and a step 4 is formed at the joint part of the plugging part and the cylindrical barrel 1. The conical end head 2 is correspondingly provided with a nesting part 5, the inserting part 3 is inserted into the nesting part 5, and the bottom end opening 6 of the nesting part 5 is abutted against the step 4. The above examples constitute the detachable connection structure. In other embodiments, the top end of the cylindrical barrel 1 and the bottom end of the conical end head 2 may be detachably connected by threaded connection, snap connection, latch connection, pin connection or other plugging modes.

When the pyrotechnic composition is filled, a die rod (not shown in the figure) driven by the hydraulic press is pressed down and inserted into the bottom end port 7 of the inverted cylindrical barrel 1, the top end port 8 of the cylindrical barrel 1 is downward abutted with a substrate (not shown in the figure), and the pyrotechnic composition (not shown in the figure) in the inner cavity of the cylindrical barrel 1 can be ensured to be pressed into a compact cylindrical composition due to the fact that a round head part is not arranged, so that the realization of the ignition effect is ensured; after the pyrotechnic composition is filled, the top end of the cylindrical barrel body 1 is connected with the conical end head 2, and when the cylindrical barrel body is launched and lifted off, the conical end head 2 realizes a guiding function to ensure that the whole straight line of the lift-off effect cartridge is lifted off.

Example 2: referring to fig. 5-6, another specific configuration of the present utility model is reflected. Unlike example 1, in example 1, the top port 8 of the cylindrical barrel 1 was not closed, and the top port 8 was closed by a base plate, thereby completing the pressing with a die bar. The closed top end opening 201 of the cylindrical barrel in this example is beneficial to further ensuring the drug compactness.

Example 3: referring to fig. 7-8, another specific configuration of the present utility model is reflected. The difference from embodiment 1 is that, in the example, the top ends of the three cylindrical barrels 301 are provided with plug parts 302, and the top ends of the plug parts 302 are provided with fire transmission holes 303; the three plug-in parts 302 are respectively inserted into the bottom end opening 304 of the last cylindrical barrel in a nested manner, and the plug-in part 301 of the uppermost cylindrical barrel 301 is inserted into the nesting part 306 of the conical end head 305. Thereby forming a multi-section lift-off effect cartridge, each section of cylindrical barrel 301 can be filled with pyrotechnic compositions with different effects, and fire transmission connection is realized through the fire transmission holes 303, wherein the fire transmission connection mode can be that a lead wire or fire transmission composition or flame injection is arranged. The technical scheme is favorable for realizing the combination of more setting-off effects.

Example 4: referring to fig. 9-12, another specific configuration of the present utility model is reflected. Unlike embodiment 1, in the example, the lift-off effect cartridge 401 is provided with a launch canister 402, the launch canister 402 is filled with a propellant powder (not shown in the figure), the lift-off effect cartridge 401 is arranged above the propellant powder in the launch canister 402, and a positioning slot 404 of a fire transmission lead 403 is provided on the bottom end surface of the launch canister 402. After ignition of the fire transfer leads 403 by the ignition leads 406, the propellant powder explosive gases do work in the interior cavity of the propellant canister 402 to launch the lift-off effect cartridge 401 off. The propellant blasting gas also transfers a fire to ignite the pyrotechnic charge in the lift-off effect cartridge 401.

In the example, a plurality of the emission barrels 402 are combined in parallel to form an annular body, and the positioning grooves 404 of each emission barrel 402 are combined to form circular closed-loop distribution. The annular body is nested inside the top port of the outer cylinder 405; in order to facilitate the axial positioning of the annular body in the example, an annular positioning step 407 is arranged on the outer side of the annular body, and the annular positioning step 407 abuts against the end face of the top port of the outer cylinder 405.

In the example, the bead-spitting product of the garland fireworks is arranged in the inner hole of the annular body, and when the product is set off, the emitted bead-spitting product is ejected from the inner hole of the annular body, so that the setting-off effect of the bead-spitting product is not influenced; in other embodiments, a plurality of transmitting cylinders can be installed in the inner hole of the annular body, the bead-discharging product of the Callin fireworks is arranged on the periphery of the annular body, and when the annular body is set off, the transmitted bead-discharging product is emitted from the periphery of the annular body, so that the setting-off effect of the bead-discharging product is not influenced. The annular body is circular in the example, and in other embodiments, the annular body or closed loop may be square or other shapes.

The multiple emission barrels 402 combined into the annular body are respectively loaded with the lift-off effect cartridge 401, and are serially connected with the fire transmission leads 403 in the positioning grooves 404 for ignition, so that the combination of the bead-spitting effect and other setting-off effects can be conveniently and reliably realized; the positioning grooves of the cylinders are distributed circularly, so that one fire transmission lead 403 is connected in series to connect each lift-off effect cartridge 401, and the assembly and the setting-off are convenient.
