[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figures 1-4 This utility model provides a technical solution: a portable launcher quick reset structure, comprising: a launcher housing 1, a safety 2, a trigger 3, a launch tube mounting slot 4, a flag-shaped component 14, a trigger top rod 16, and a torsion spring 17. The safety 2 is rotatably connected to the outside of the launcher housing 1, and the trigger 3 is installed on the outside of the launcher housing 1. The launch tube mounting slot 4 is installed on the top of the launcher housing 1, and the trigger top rod 16 is slidably connected to the inside of the launcher housing 1. The flag-shaped component 14 is rotatably connected to the inside of the launcher housing 1, and a torsion spring 17 connects the launcher housing 1 and the flag-shaped component 14. The linkage of the assembled parts realizes the reset function of the safety 2 and the trigger 3. When firing, pulling the trigger 3 causes the trigger top rod 16 to move forward, and the flag-shaped component 14, under the action of the torsion spring 17, locks the trigger 3 downward, maintaining the trigger 3 in the firing state.

[0022] A reset shaft 5 is rotatably connected to the inner side of the mounting hole of the transmitter housing 1, and a reset spring 6 is installed at the bottom of the reset shaft 5. The reset shaft 5 can move up and down along the mounting hole of the transmitter housing 1. A sliding groove is opened in the middle of the reset shaft 5, and a first connecting rod 7 is slidably connected to the inner side of the sliding groove, which can provide free travel for the up and down movement of the first connecting rod 7. A pawl 9 is connected to the outer side of the first connecting rod 7. The first connecting rod 7 can drive the pawl 9 to move up and down. The pawl 9 can lock the ratchet 10 by inserting into the teeth of the ratchet 10, and the ratchet 10 is fixedly connected to the shaft end of the safety 2. The up and down movement of the reset shaft 5 can drive the pawl 9 to achieve the engagement and disengagement of the ratchet 10. A spring 8 is installed on the inner side of the transmitter housing 1, and the spring 8 presses on the pawl 9 for... Ensure that pawl 9 is pressed against ratchet 10 to achieve self-locking. Ratchet 10 is rigidly connected to the semicircular safety shaft 15. When safety 2 is activated, ratchet 10 is driven. Ratchet 10 is equipped with torsion spring 17, which can reset safety 2 when pawl 9 is separated. Ratchet 10 has a cam structure, which can drive the reset hook 12 to rotate through the second linkage 11. The reset hook 12 can rotate around the mounting shaft, and its head can push the flag-shaped part 14 upward to release the restriction of trigger 3. Trigger 3 is reset under the force of torsion spring 17. The manual reset safety 2 safety reset lever 13 is coaxial with the safety 2 shaft. Activating the safety reset lever 13 can lift pawl 9 and separate it from ratchet 10 to achieve manual safety reset.

[0023] The safety mechanism of the transmitter is as follows: When the safety 2 is in the "safe" position, the semicircular safety 15 is pressed against the rear of the trigger 3, preventing the trigger 3 from being pulled backward, thus achieving the "safety". When the safety 2 is pulled, the semicircular safety 15 rotates. When the safety 2 is pulled to the "fire" position, the semicircular safety 15 rotates out of contact with the rear of the trigger 3, allowing the trigger 3 to be pulled backward and releasing the "safety".

[0024] The trigger principle of the launcher: After the safety 2 is turned to the "fire" position, the trigger 3 is pulled. The trigger top lever 16 moves forward, and the flag-shaped part 14 moves downward under the action of the torsion spring 17, locking the trigger top lever 16 and fixing the trigger 3 in the firing position, thus completing the firing.

[0025] Before the transmitter docking, the safety 2 is in the "safe" position, and the trigger 3 is not pulled. At this time, the return spring 6 pushes the return shaft 5 upward, which pulls the first link 7 upward, causing the pawl 9 to move upward, keeping the pawl 9 disengaged from the ratchet 10. After the transmitter housing 1 is docked with the launch tube, the return shaft 5 is pressed downward by the launch tube, releasing the force pulling the second link 11 upward. The spring 8 then presses the pawl 9 downward, and the pawl 9 engages the ratchet 10. When the safety 2 is pulled, the safety shaft semicircle 15 and the ratchet 10 rotate counterclockwise, stopping when it reaches the "fire" position. The ratchet 10 is locked by the pawl 9, ensuring that the safety 2 is fixed in the "fire" position. As the ratchet 10 rotates, the cam on one side of the ratchet 10 drives the first link 7 downward, pulling the return hook 12 to rotate clockwise downward, maintaining a certain distance from the flag-shaped part 14. At this time, the trigger 3 can be pulled. The top lever 16 is held in place by the flag-shaped piece 14, thus completing the firing state. After firing, the launcher housing 1 is removed from the launch tube. Since there is no pressure from the launch tube, the return spring 6 pushes the return shaft 5 upward. The return shaft 5 pulls the second link 11 upward, causing the pawl 9 to disengage from the ratchet 10. The ratchet 10 rotates clockwise under the action of the torsion spring 17, causing the safety shaft semicircle 15 to rotate, so that the safety 2 is turned to the "safe" position, realizing the automatic reset of the safety 2. When the ratchet 10 rotates, the cam on one side pushes the first link 7 upward, pushing the reset mechanism 12 upward to hold the flag-shaped piece 14, lifting the flag-shaped piece 14 upward, releasing the restriction on the trigger top lever 16. The trigger 3 returns to the position before being pulled under the action of the torsion spring 17, realizing the automatic reset of the trigger 3.

[0026] In actual operation, there may be situations where the safety 2 is moved to the "fire" position and then the firing is canceled. In this case, the safety reset lever 13 can be moved forward. The safety reset lever 13 shaft lifts the pawl 9 upward, releasing the ratchet 10 from the pawl 9. The ratchet 10 then drives the safety shaft semicircle 15 to rotate to the "safe" position, realizing the manual reset of the safety 2. This invention adopts a ratchet structure, realizing the dual automatic reset of the launcher safety 2 and trigger 3, while retaining the manual reset function of the safety 2. This structure is ingeniously designed and reliable. The entire reset structure is ultimately designed as an independent assembly, which can be assembled and then assembled onto the launcher as a whole, reducing assembly difficulty and improving assembly efficiency, realizing modular design. In actual use, the automatic reset function can reduce manual operation, ensure operation speed and sustainability, thereby improving the efficiency of equipment use in wartime, which is of great significance in the real combat environment where every second counts.

[0028] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
