[0016] The present invention will be further described in detail below with reference to the accompanying drawings. Example

[0017] like Figure 1-3As shown, this utility model discloses an 82-type grenade pull-and-throw integrated thrower, including a base 1. The lower end of the base 1 has a grenade receiving slot 11 for accommodating grenades. The four sides of the base 1 are respectively provided with a pull-and-throw component 2, a first fixing component 3, a second fixing component 4, and a snap-fit ​​component 5. The side wall of the base 1 where the pull-and-throw component 2 is located is parallel to the side wall of the base 1 where the second fixing component 4 is located. The side wall of the base 1 where the first fixing component 3 is located is parallel to the side wall of the base 1 where the snap-fit ​​component 5 is located. One end of the first fixing component 3 is connected to the snap-fit ​​component 5. The pull-and-throw component 2 controls the connection between the snap-fit ​​component 5 and the first fixing component 3. The Type 82 grenade is placed in the grenade receiving slot 11. The first fixing component 3 is connected to the snap-fit ​​component 5 to secure the Type 82 grenade. The base 1 is connected to the drone via the second fixing component 4. The safety pull ring of the Type 82 grenade is connected to the release component 2. When the drone flies to the target area, the release component 2 is activated, pulling the safety pull ring of the Type 82 grenade. Simultaneously, the snap-fit ​​component 5 is separated from the first fixing component 3, and the first fixing component 3 disengages from the snap-fit ​​component 5, thus releasing the fixation of the Type 82 grenade. The Type 82 grenade falls to the target area under the influence of gravity. Using this device, it is not necessary to remove the safety pull ring of the grenade in advance, ensuring the safety of the grenade's attachment to the drone. Furthermore, when the combat mission is canceled, the grenade can be reused because the safety pull ring was not removed in advance.

[0018] The grenade-throwing assembly 2 includes a servo motor 21, a gear 22, a rack 23, and a track 24. A slot 12 is provided on the side wall of the base 1. The servo motor 21 is fixedly installed in the slot 12. The gear 22 is fixedly installed on the output shaft of the servo motor 21. The track 24 is fixedly installed on the side wall of the base 1. The track 24 is located on the side of the slot 12 away from the snap-fit ​​assembly 5. The rack 23 is slidably connected to the track 24. The cross-section of the rack 23 is dovetail-shaped. The track 24 has a dovetail groove that matches the rack 23. The rack 23 meshes with the gear 22. A pull ring rod 25 is fixedly connected to the end of the rack 23 near the grenade receiving slot 11. A stop rod 26 is connected to the end of the pull ring rod 25 away from the rack 23 by a screw. A push assembly 27 is fixedly connected to the rack 23. The push assembly 27 is used to drive the snap-fit ​​assembly 5. The pushing assembly 27 includes a crossbar 28 and a push rod 29. One end of the crossbar 28 is fixedly connected to the rack 23, and the other end is fixedly connected to the push rod 29. The crossbar 28 is perpendicular to the direction of movement of the rack 23, and the push rod 29 is perpendicular to the crossbar 28. The push rod 29 is used to drive the locking assembly 5. When the grenade is installed, the stop lever 26 is loosened by screws, and the safety ring of the grenade is put onto the pull ring lever 25. Then the stop lever 26 is fixed. When the stop lever 26 is fixed, it rotates towards the gear 22. The stop lever 26 can prevent the safety ring of the grenade from falling off the pull ring lever 25. When the grenade needs to be thrown, the servo motor 21 drives the rack 23 to move away from the grenade through the gear 22, thereby pulling out the safety ring of the grenade. At the same time, the push rod 29 pushes the locking assembly 5, separating the locking assembly 5 from the first fixing assembly 3, releasing the grenade from its fixation, and the grenade falls under the action of gravity.

[0019] The snap-fit ​​assembly 5 includes a fixed box 51, a first snap-fit ​​rod 52, and a second snap-fit ​​rod 53. The fixed box 51 is fixedly connected to the side wall of the base 1. The first snap-fit ​​rod 52 and the second snap-fit ​​rod 53 are both rotatably connected to the inner cavity of the fixed box 51. Notches 54 are provided on both parallel side walls of the fixed box 51. One end of the first snap-fit ​​rod 52 passes through the notch 54, and the other end snaps into the second snap-fit ​​rod 53. As the push rod 29 moves with the rack 23, it pushes one end of the first snap-fit ​​rod 52 that protrudes from the fixed box 51. When pushed, a first spring piece 55 is fixedly connected to the side of the first locking rod 52 near the pushing component 27. The first spring piece 55 contacts the inner wall of the fixing box 51. One end of the second locking rod 53 is engaged with the first locking rod 52, and the other end is fixedly connected with a second spring piece 56. A first limiting block 57 is fixedly connected in the inner cavity of the fixing box 51. The second spring piece 56 contacts the first limiting block 57. A slot 58 is opened on the second locking rod 53, and one end of the first fixing component 3 is engaged in the slot 58. The first fixing component 3 includes a strap 31 and a retaining ring 32. A baffle 14 is integrally formed on the side wall of the base 1. One end of the strap 31 is fixedly connected to the baffle 14, and the other end is fixedly connected to the retaining ring 32. The retaining ring 32 passes through the notch 54 and is engaged in the slot 58. When securing the grenade, the safety lever rests against the side wall of the baffle 14, and the locking ring 32 engages with the slot 58 through the notch 54. When the grenade is released, the push rod 29 pushes the first locking lever 52 to rotate, compressing the first spring 55 and causing the second locking lever 53 to separate from the first locking lever 52. The second locking lever 53 rotates under the elastic force of the second spring 56, thus disengaging the locking ring 32 from the slot 58. Alternatively, when the mission is canceled, the safety pull ring of the grenade can be removed from the pull lever 25, and the first locking lever 52 can be manually moved to disengage the locking ring 32 from the slot 58, allowing the grenade to be removed from the drone.

[0020] To facilitate the positioning and fixing of the grenade, a second limiting block 13 is fixedly connected to the side wall of the base 1. The second limiting block 13 is located on the side of the grenade receiving slot 11 near the throwing assembly 2.

[0021] In this embodiment, the second fixing member 4 has a dovetail-shaped cross-section and is integrally formed with the base 1. This embodiment only uses one of the fixing methods.

[0022] The specific working principle of this embodiment is as follows: The base 1 is connected to the UAV via the second fixing member 4. The grenade is placed in the grenade receiving slot 11, and the retaining ring 32 is inserted into the retaining groove 58. The grenade is secured with straps 31. When the UAV flies to the target position and needs to drop the grenade, the servo motor 21 is rotated, which drives the gear 22 to rotate. The gear 22 drives the rack 23 to move away from the grenade. During the movement, the pull rod pulls out the safety ring of the grenade. At the same time, the push rod 29 pushes the first retaining rod 52 to rotate, and the second retaining rod 53 rotates under the action of the second spring 56, thereby disengaging the retaining ring 32 from the retaining groove 58. In addition, when the combat mission is canceled, the safety ring of the grenade can also be removed from the pull ring assembly, and the first retaining rod 52 can be manually moved to disengage the retaining ring 32 from the retaining groove 58, thus removing the grenade from the UAV.

[0023] The control of the servo motor in this application adopts the remote control technology in the prior art, so this application will not elaborate on the prior art.
