摘要:
The present invention discloses a bottom plug pre-installed with heat resistance wire and corresponding locking base for single-shot firework, the top of a plastic plug (1) provides a heating resistance wire slot (4), a heating resistance wire (3) is fixed into the heating resistance wire slot (4) and two ends thereof are respectively electrically connected with the two metal conductors (12), the other ends of the two metal conductors (12) are respectively electrically connected with two plate-like electrodes (13) and fixed to the bottom of the plastic plug (1), the bottom of the plastic plug (1) provides an upper clamping structure (17), a locking base (2) provides a lower clamping structure (8), the lower clamping structure (8) is correspondingly clamped with the upper clamping structure (17) of the plastic plug (1), the top of the locking base (2) is provided with two flexible electrodes (5), the two flexible electrodes (5) are respectively aligned with and electrically connected with the two plate-like electrodes (13) of the plastic plug (1), and the flexible electrodes (5) are electrically connected to a circuit connecting socket (10) fixed onto the locking base (2). The present invention makes the bursting energy of the lifting charge highly efficient at projecting the firework effects, has a high security coefficient, stable and reliable performance, and is convenient to use.
摘要:
A fireworks igniter system and method for safely igniting fuse-type fireworks including a handheld igniter module (1) and a remote control module (2). An igniter head at the proximal end of the igniter module (1) includes a heater element (24) and fuse clamp slide (10-12) which receives and biasingly molds the fuse (70) against the heater element (24). A microprocessor (64) in the igniter module (1) includes an infrared receiver (54) and an igniter module actuator (14,16). The remote control module (2) includes an infrared emitter (84) and a remote control module actuator (90), the infrared emitter (84) emitting a coded IR signal in response to activation of the actuator (90). The IR signal is sensed by the infrared receiver (54) to activate the igniter module actuator (14,16) and deliver electric current to the heater element (24) sufficient to ignite the fuse (70).
摘要:
Zur Lösung der Aufgabe, einen Bodenfeuerwerkskörper (1) mit einer erhöhten Standsicherheit zu schaffen, wird vorgeschlagen, diesen Feuerwerkskörper mit einer in etwa dem Grundriß seines Aufnahmeteils entsprechenden Bodenplatte (12) zu versehen, die an ihren Rändern mit Verbreiterungselementen (11) versehen ist.
摘要:
Bei Übladungen (1) besteht die Bedingung, daß nach Zündung der pyrotechnischen Ladung (9) wegfliegende Verschlußteile eine bestimmte Flugweite nicht überschreiten und eine sehr kleine kinetische Energie aufweisen. Nach der Erfindung wird dies dadurch erreicht, daß die pyrotechnische Ladung (9) durch einen durch den Gasdruck der Ladung (9) zu öffnenden Verschluß (30) in einem Ladungsrohr (3) verschlossen ist. Der Verschluß (30) besteht aus einer Kugel (18) aus einem leichten, geschäumten Werkstoff und aus einer klebenden Verbindung aus einem vulkanisierbaren Silikonkautschuks in Form einer deckelförmigen Silikonschicht (21).
摘要:
L'élément d'artifice pyrotechnique est du type destiné à être suspendu au-dessus du sol. Il comporte des grains de matière pyrotechnique (2) d'une taille qui est fonction de leur durée de combustion moyenne requise conditionnés dans un emballage constitué d'au moins une feuille en papier (1). Les grains (2) sont étalés et maintenus sur la surface de la feuille qui constite également des moyens de mise à feu de ceux-ci. La feuille (1) est repliée ou enroulée sur elle-même et est, à sa partie supérieure, pourvue d'un ruban adhésif (3) destiné à maintenir la feuille dans son état plié ou enroulé. L'élément d'artifice comporte, à sa partie inférieure, une couche d'allumage (5) et, à sa partie supérieure, un ruban de rigidification (4).
