[0037] The present invention will be described in detail below with reference to the drawings and in combination with embodiments.

[0038] The tear gas bomb launcher of the present invention includes

[0039] a magazine fixing part 1, which is provided with a plurality of launch ports 11 along the length direction and trigger slot holes 12 corresponding to the launch ports 11;

[0040] A cartridge magazine 2, which can be placed inside the fixing part 1 of the cartridge magazine 2. The cartridge magazine 2 is provided with accommodation cavities 21 corresponding one by one to the firing ports 11. During operation, each accommodation cavity 21 accommodates a tear gas bomb. One end of the cartridge magazine 2 extends outwards to form a fixing edge 22. A first locking hole 23 is formed on the fixing edge 22. A locking cavity 24 is fixedly arranged below the fixing edge 22. A ball 25 that can pop out of the locking cavity 24 is arranged inside the locking cavity 24. A pressing piece 26 is fixedly arranged at the top end of the ball 25. The pressing piece 26 extends vertically upwards to form a locking tongue 27. A second locking hole 13 corresponding to the first locking hole 23 is formed at the end of the cartridge magazine fixing part 1. When the ball 25 pops outwards, the locking tongue 27 can pass through the first locking hole 23 and the second locking hole 13. When the pressing piece 26 is pressed downwards, the pressing piece 26 drives the locking tongue 27 to disengage from the second locking hole 13, so that the cartridge magazine 2 is separated from the cartridge magazine fixing part 1;

[0041] A firing part 3, which is sleeved on the cartridge magazine fixing part 1 and can move along the length direction of the cartridge magazine fixing part 1. One end of it is fixedly provided with a firing tube 31. The firing tube 31 can correspond to the firing port 11 of the cartridge magazine fixing part 1. The other end is fixedly provided with a trigger unit 32. The trigger unit 32 can correspond to the trigger slot hole 12. Slide ways 15 are fixedly arranged along both sides of the cartridge magazine fixing part 1 along the length direction of the cartridge magazine 2. A sliding groove 34 that cooperates with the slide ways 15 is formed on the firing part 3. A rack part 14 is fixedly arranged on the cartridge magazine fixing part 1 along the length direction. A traveling motor 33 is fixedly arranged on the firing part 3. A traveling gear 35 is coaxially fixedly connected to the output shaft of the traveling motor 33. The traveling gear 35 meshes with the rack part 14. During operation, the traveling gear 35 is controlled by the traveling motor 33. Through the cooperation of the traveling gear 35 and the rack part 14, the firing part 3 moves along the cartridge magazine fixing part 1, so that during the movement of the firing part 3, the trigger unit 32 and the firing tube 31 can successively correspond to the accommodation cavities 21;

[0042] The trigger unit 32 includes a fixed seat 321, a firing pin 322 and a hammer 323. The fixed seat 321 includes a fixing plate 3211 and side plates 3212 extending from both sides of the fixing plate 3211. The firing pin 322 and the hammer 323 are both disposed between the two side plates 3212. A guiding block 3213 is fixedly provided on the fixing plate 3211. A guiding hole 28 is formed on the firing part 3. The guiding block 3213 passes through the guiding hole 28 and is disposed in the trigger slot hole 12. A firing pin hole 32131 is formed on the guiding block. A flange 32132 extends inwards from one end of the firing pin hole 32131 close to the trigger slot opening 16. The firing pin 322 is disposed in the firing pin hole 32131 and can pass through the firing pin hole 32131 and be disposed in the receiving cavity 21 to trigger the primer of the tear gas bomb in the receiving cavity 21. A guiding groove 32133 is formed at the bottom of the guiding block 3213. A protection block 38 capable of moving synchronously with the firing pin 322 is provided below the firing pin 322. The protection block 38 is disposed in the guiding groove 32133. A guiding groove opening 29 corresponding to the guiding groove 32133 is formed at the bottom of the guiding hole 28. A trigger slot opening 16 corresponding to the receiving cavity 21 is formed at the bottom of the trigger slot hole 12 along the length direction. When the end of the firing pin 322 enters the receiving cavity 21, the protection block 38 can pass through the guiding groove opening 29 and enter the trigger slot opening 16. When a failure occurs, the protection block 38 moves forward, passes through the guiding groove opening 29 and abuts against the outer wall of the firing part 3. At this time, the firing pin 322 is still in the firing pin hole 32131, preventing damage to the firing pin 322. Chamfers are formed on both sides of one end of the protection block 38 facing the trigger slot opening 16 to facilitate the guiding block 3213 to enter the trigger slot opening 16 and prevent the protection block 38 from affecting the launch of the tear gas bomb;

[0043] The firing pin 322 includes an impact part 3222 and a primer trigger part 3221. The diameter of the impact part 3222 is larger than that of the primer trigger part 3221. A spring 37 is sleeved on the impact part 3222. A connecting part 381 extends upwards from one end of the protection block 38 away from the trigger slot hole 12. A through hole is formed at the top of the connecting part 381. The connecting part 381 is sleeved on the primer trigger part 3221 of the firing pin 322 through the through hole. One end of the spring 37 abuts against the flange 32132, and the other end abuts against the connecting part 381. A receiving groove 32134 is formed on the guiding block 3213. The connecting part 381 is disposed in the receiving groove 32134.

[0044] A shaft hole is formed in the side plate 3212. A rotating shaft 39 passes through the shaft hole. The top end of the striking hammer 323 is fixedly connected to the rotating shaft 39. The body of a torsion spring is sleeved on the rotating shaft 39. The two torsion feet of the torsion spring 3231 respectively abut against the striking hammer 323 and the fixing plate 3211. A driven gear 391 is coaxially and fixedly provided on the rotating shaft 39. A striking generator 324 is fixedly provided on the fixing seat 321. A striking gear 325 is fixedly provided on the output shaft of the striking generator 324. The striking gear 325 includes a convex tooth portion 3251 meshing with the driven gear 391 and a smooth portion 3252. A limiting shaft 326 is also fixedly provided between the two side plates 3212. A cutting surface 32221 and a limiting arc surface 32222 tangent to the cutting surface 32221 are formed in the impact portion 3222 of the firing pin along its own length direction. The limiting shaft 326 can abut against the limiting arc surface 32222. During the working process, the convex tooth portion 3251 of the striking gear 325 drives the driven gear 391, so that the striking hammer 323 rotates around the axis of the rotating shaft, compresses the torsion spring 3231 to form elastic potential energy. When the striking gear 325 rotates until the convex tooth portion 3251 is separated from the driven gear 391, the striking hammer 323 impacts the firing pin 322 under the drive of the torsion spring 3231, so that the firing pin 322 triggers the primer powder of the tear gas bomb in the accommodation cavity 21. The magazine fixing part can be carried on a drone, and the drone is controlled for remote control to launch a tear gas bomb at a target.

[0045] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
