The invention discloses a triggering device, which comprises a supporting seat, a heavy hammer and a conductive wire, wherein a cylindrical conductive cylinder with an open lower end is fixedly arranged on the lower surface of the supporting seat, the axis of the conductive cylinder is perpendicular to the supporting seat with the foot of a perpendicular being an original point, the conductive cylinder is connected with the top end of a conductive rod at the position of the original point on the lower surface of the supporting seat, the conductive heavy hammer is fixedly mounted at the bottomend of the conductive rod, the bottom end of the conductive rod is pulled by the gravity of the heavy hammer to move freely, one end of a conductive wire is electrically connected with the conductivecylinder, the other end of the conductive wire is electrically connected with the conductive rod, and a power source and an ignition head are connected to the conductive wire. The triggering device disclosed by the invention can ignite regularly, and does not need to depend on a timer or a height setter to preset the time or height. Taking a rocket model as an example, when a rocket reaches the highest point, the heavy hammer automatically swings to one side by means of gravity to be in contact with the conductive cylinder to form a triggering circuit of the ignition head, the ignition head istriggered to burn, and a cord connecting a cabin cover and a cabin body of the rocket is burnt out, so that the cabin cover is opened.
本发明公开了一种触发装置,包括:支撑座、重锤和导电电线,支撑座的下表面固装有一下端敞口的圆柱形的导电筒,导电筒的轴心与支撑座垂直且垂足为原点,在支撑座的下表面的原点位置与一导电棒的顶端连接,导电棒的底端固装有能够导电的重锤,导电棒的底端在该重锤重力的拉动下自由活动,导电电线的一端与导电筒电连接,另一端与导电棒电连接,在导电电线上连接有一电源和点火头。本发明的触发装置能够定时点火,无需依赖定时器或定高器预设时间或高度,以火箭模型为例,火箭到达最高点时,重锤依靠重力自动摆动至一侧从而与导电筒接触,形成点火头的触发电路,触发点火头燃烧,烧断连通火箭舱盖与舱体的线绳,从而使舱盖打开。
