Detailed ways

The present utility model will be described in detail below with reference to the accompanying drawings and embodiments.

This embodiment provides a crossbow shooting model rocket system, which uses a model rocket to replace arrows, and the crossbow shooting model rocket system includes a crossbow shooting system and a model rocket system.

As shown in Figures 1 (a) and (b), the crossbow shooting system can use a common crossbow, including a bow body 1, a bow string 2, a trigger 3 and a bow string hook 4. The bow body 1 is provided with a guide groove, which cooperates with a fin of the model rocket system. Since the fin is fixed on the model rocket, it can ensure that the model rocket system moves along the guide groove and will not deviate from the direction.

As shown in Figure 2, the model rocket system includes a model rocket body, a model rocket solid motor 6 and a remote power supply device. Model rocket solid motor 6. The long-distance electrification device is installed in the model rocket body to form a model rocket. The propellant of the model rocket system adopts solid propellant, and the reaction force generated by the backward injection of the solid propellant propels the model rocket forward. .

The function of the long-distance power-on device is a circuit switch. In the storage state, the power-on device is in an off-circuit state. Only after the model rocket system moves a certain distance on the crossbow shooting system, it is turned on and the model rocket solid motor 6 is ignited. The remote power-on device includes a time delay battery system 5 , a wire 7 , a pulling circuit system 8 , a pulling ring 10 , a pulling rope 11 and an electric ignition head 9 . As shown in FIG. 3 , the pulling circuit system 8 is composed of two conductive sheets 12 and one insulating sheet 13, and the insulating sheet 13 is placed between the two conducting sheets 12 so that the two conducting sheets 12 do not contact each other and do not Conducting electricity; one end of the pull rope 11 is connected with the insulating sheet 13 through the pull ring 10, and the other end of the pull rope 11 is fixed on the crossbow; the delay battery system 5 is electrically connected with the conductive sheet 12 through the wire 7 to provide the electric ignition head 9 for delayed ignition Energy and delay time; the conductive sheet 12 is connected to the ignition head 9 through the wire 7. After the two conductive sheets 12 are turned on, the electric ignition head 9 fires after the delay battery system 5 delays power supply.

In the unloaded state, the insulating sheet 13 isolates the two conductive sheets 12, so that the entire ignition circuit is in an open-circuit state, and the electric ignition head 9 cannot be fired; when the model rocket system is placed on the crossbow, it will be fixed on the crossbow shooting system. The pull rope 11 is fixed on the pull ring 10, but the pull rope 11 is not tightened. At this time, the entire ignition circuit is still in an open circuit state; when the trigger 3 is pulled, the fins of the model rocket system slide along the guide groove of the bow body 1, and the ejection The function launches the model rocket system so that the model rocket system obtains sufficient initial speed. When the model rocket system is ejected by the crossbow shooting system and leaves a distance from the origin, the pull rope 11 fixed on the crossbow shooting system pulls the insulating sheet 13 away from the two conductive sheets 12 through the pull ring 10. At this time, the two conductive sheets 12 are in contact with each other, causing the entire ignition circuit to be turned on, but there is a capacitor in the delay battery system 5 that can delay the power supply, and delay the power supply of the battery system 5 for a certain time within 0 to 4s, causing the electric ignition head 9 to fire and ignite the model rocket Solid motor 6, which propels the model rocket system to move, and the flight trajectory is seen by the traces left by the flying smoke.

To sum up, the above are only preferred embodiments of the present invention, and are not intended to limit the protection scope of the present invention. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
