Description

Technical Field

[0001] The utility model relates to the technical field of marble compound bows, and specifically relates to a ballistic device applied to the launch of marble compound bows. Background Technique

[0002] A marble compound bow is a compound bow that can launch marbles. Using inexpensive and small-sized marbles to replace arrow shafts allows more people to enjoy the fun of drawing the bow.

[0003] The Chinese patent discloses a compound bow ballistic device and a compound bow applied to the launch of ferromagnetic marbles, with the publication number CN217083493U, which includes a ballistic rod and a bullet positioning component. The ballistic rod is provided with a bullet chamber and a string travel port. The length directions of the bullet chamber and the string travel port are both parallel to the length direction of the ballistic rod. The cross-section of the bullet chamber is a circle adapted to the diameter of the marble. The string travel port penetrates through the upper, lower, and rear end faces of the ballistic rod, and the center line of the string travel port coincides with the center line of the bullet chamber. The ballistic rod is provided with a loading port communicating with the bullet chamber. The bullet positioning component includes a magnetic attracting block fixedly connected to the ballistic rod for attracting the marble to be launched. The magnetic attracting block is close to the loading port and is located in front of the loading port; the compound bow includes a bow body and the above-mentioned compound bow ballistic device applied to the launch of ferromagnetic marbles. The utility model has higher accuracy when launching marbles, is simple and reliable in structure, and is convenient for maintenance.

[0004] However, it still has the following disadvantages: When the device is in use, the bowstring is hooked with the fingers and pulled backward to store energy in the bowstring. For a compound bow with greater power, it is more difficult to pull the bowstring, making it more difficult to store energy. For this reason, we have proposed a ballistic device applied to the launch of marble compound bows to solve this problem. Content of the Utility Model
