[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a rail-mounted fire extinguishing projectile launching device for firefighting drones.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A sliding rail type fire-fighting drone airborne fire extinguishing projectile launching device includes a body, the bottom of which contacts a projectile magazine. The upper rear end of the projectile magazine has a loading port, and the lower front end of the projectile magazine has a discharge port. A sliding rail is fixedly connected to the bottom inner side of the projectile magazine, and the sliding rail is inclined. A fixing plate is fixedly connected to the upper front end of the projectile magazine. An electric push rod is fixedly installed at the bottom of the fixing plate. A connecting plate is fixedly connected to the end of the telescopic shaft of the electric push rod. A baffle is fixedly connected to the side of the connecting plate near the projectile magazine. The baffle is slidably connected to the projectile magazine, and the position of the baffle corresponds to the position of the discharge port.

[0007] Furthermore, a preferred structure has two frames fixedly connected to the bottom of the fuselage, and the two frames are symmetrically arranged. The height of the frames is higher than the magazine, so that when the whole unit is on the ground, the magazine is suspended in the air and is not easily damaged by impacts from the ground.

[0008] Furthermore, in a preferred configuration, two mounting seats are fixedly connected to the bottom of the body, and the magazine contacts both mounting seats. Mounting blocks are fixedly connected to both sides of the magazine, and the mounting blocks engage with the mounting seats. An inclined seat is slidably connected inside the mounting seat, and a locking pin is fixedly connected to the inclined seat. The locking pin penetrates the mounting seat and is slidably connected to it, and is inserted into the mounting blocks. A pusher is slidably connected to the bottom of the mounting seat, and the pusher penetrates the mounting seat. The arc-shaped end of the pusher abuts against the inclined surface of the inclined seat. Through the cooperation of the pusher and the inclined seat, the engagement and disengagement of the locking pin and the mounting blocks can be controlled, thereby facilitating quick assembly and disassembly of the magazine from the bottom of the body.

[0009] Furthermore, in a preferred configuration, a guide rod is fixedly connected to the inner wall of the mounting base, the guide rod is slidably connected to the inclined seat, and a spring is installed inside the inclined seat. One end of the spring is fixedly connected to the guide rod, and the other end of the spring is fixedly connected to the inner surface of the inclined seat. The guide rod and spring provide guidance for the inclined seat's movement and assist in its repositioning.

[0010] Furthermore, in a preferred configuration, a pressing block is fixedly connected to the bottom of the pusher, a protective sleeve is fixedly connected to the upper edge of the pressing block, and the top of the protective sleeve is fixedly connected to the bottom of the mounting base. The pressing block increases the contact area between the pusher and the fingers, thus facilitating the pushing of the pusher.

[0011] Furthermore, in a preferred configuration, a limiting ring is fixedly connected to the push pin, and the limiting ring contacts the inner surface of the mounting base. The limiting ring provides axial restraint for the push pin.

[0012] The beneficial effects of this utility model are as follows: By adding an ammunition magazine to the bottom of the machine body, the magazine is equipped with an ammunition loading port and an ammunition dispensing port. At the same time, an inclined slide rail is set inside the magazine. The inclined structure of the slide rail uses gravity to assist in the feeding of ammunition, reducing the risk of jamming. In addition, the front end of the magazine is equipped with a baffle driven by an electric push rod, which can quickly open and close the ammunition dispensing port to ensure orderly single-shot delivery and significantly improve the efficiency of fire extinguishing ammunition delivery. By setting up a mounting base, mounting block, locking pin, guide rod, spring and sliding pin between the magazine and the machine body, the locking pin is fixed by the insertion of the mounting block, and the inclined unlocking mechanism of the slide rail enables the rapid replacement of the magazine, meeting the needs of continuous operation in fire fighting missions.
