Detailed Description

The invention is shown in figures 1-4, and comprises a gun barrel 1 and a slide block self-locking mechanism 2, wherein the gun barrel 1 is in a cylindrical shape with one side opened and the other side sealed, and a pressure spring 3 is fixedly connected to the inner wall of the closed side of the gun barrel 1;

the sliding block self-locking mechanism 2 comprises a base 21, an electric push rod 22, a sliding block 23, an action rod 24 and a guide roller 25, wherein a vertical through hole 11 perpendicular to the gun barrel is formed in the side wall of the gun barrel 1, the base 21 is fixedly connected to the outer wall of the gun barrel 1 (when in actual use, the base can be connected below an unmanned aerial vehicle so as to realize the fixed connection between the gun barrel and the unmanned aerial vehicle), a limiting through hole coaxial with the vertical through hole is formed in the base 21, the action rod 24 sequentially penetrates through the limiting through hole and the vertical through hole 11, and the guide roller 25 is fixedly connected to one end, far away from the gun barrel 1, of the action rod 24;

the electric push rod 22 is fixedly connected to the base 21 and arranged along the length direction of the gun barrel 1, and the sliding block 23 is fixedly connected to an output shaft of the electric push rod 22 and linearly reciprocates under the action of the electric push rod 22; a strip-shaped through hole 230 parallel to the guide roller 25 is formed in the sliding block 23, an included angle of 10-80 degrees is formed between the strip-shaped through hole 230 and the action rod 24, and the guide roller 25 can be slidably arranged in the strip-shaped through hole 230 in a penetrating manner; therefore, after the electric push rod is started, the slide block can generate linear reciprocating motion along the length direction of the gun barrel along with the action of the electric push rod, so that the guide roller can slide in the elongated through hole in a reciprocating manner; at the moment, the strip-shaped through hole and the action rod form an included angle of 10-80 degrees, and the action rod can only do axial linear reciprocating motion in the limiting slide hole and the vertical slide hole; therefore, the reciprocating motion of the slide block can lead the action rod to do linear lifting motion, so that the bottom end of the action rod extends into the gun barrel from the vertical through hole or retracts into the limiting through hole through the vertical through hole;

the cannonball 4 is accommodated in the barrel 1, and the side wall of the cannonball 4 is provided with an annular groove 40 matched with the bottom end of the action rod 24.

When the electric sliding rod is used, the electric push rod can be started firstly, so that the sliding block slides towards one side where the electric push rod is located, and the bottom end of the action rod moves upwards and retracts into the limiting through hole; then the shell is placed in the gun barrel, and the pressure spring is compressed until the shell reaches a designated position; finally, the electric push rod is opened again, so that the slide block moves reversely, the bottom end of the action rod extends into the gun barrel downwards and is clamped into the annular groove, and the shell is axially locked.

When the cannonball needs to be thrown in, an operator opens the electric push rod in class, so that the slide block slides, the bottom end of the action rod moves upwards and retracts into the limiting through hole, the axial locking of the cannonball is released, and finally the cannonball is thrown in a sub-barrel under the action of the pressure spring and is discharged.

Slider self-locking mechanism 2 still includes C shape guide frame 20, C shape guide frame 20 fixed connection is in the top of base 21, slider 23 sliding connection is in C shape guide frame 20, still wear to be equipped with the guiding axle 231 that perpendicular to electric putter 22 axial set up in the slider 23, set up the guiding hole 201 with the rectangular shape of guiding axle 231 adaptation on the both sides wall of C shape guide frame 22, guiding hole 201 sets up along the length direction of barrel 1. Therefore, the motion range and the motion track of the sliding block can be limited, and the overall motion stability of the sliding block and the sliding block self-locking mechanism is effectively ensured.

The middle part of the side wall of the gun barrel 1 is provided with a plurality of strip-shaped air holes 10 along the length direction. Thereby the weight of the gun barrel can be obviously reduced.
