[0024] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0025] In order to solve the technical problems in the prior art that after the parachute rocket included in the parachute rocket launching device is installed in the first cylinder, the distance between the connecting part at the bottom of the parachute rocket and the bottom of the first cylinder is large, which wastes space and requires the length of the first cylinder to be set longer, resulting in high cost, the utility model provides a parachute rocket launching device, which can realize that before the parachute launching assembly is installed in the launching cavity of the parachute shooting tube (equivalent to the first cylinder in the prior art), the connecting ring can be rotated to a folded state to reduce the space occupied by the length of the connecting ring in the launching cavity, and there is no need to set the parachute shooting tube longer, thereby reducing costs.

[0026] It should be noted that the parachute rocket launcher described in the utility model is used for but not limited to aircraft, etc. For the sake of convenience, in the utility model, only the parachute rocket launcher is applied to an aircraft as an example for explanation, and the principle of the parachute rocket launcher being applied to other types of equipment is substantially the same as that of being applied to an aircraft, which will not be described one by one here. The aircraft of the present application can be but not limited to a drone, a cruise aircraft, etc.

[0027] See also Figure 1 and Figure 2 , Figure 1 and Figure 2 The schematic diagram of the structure of a parachute rocket launching device in one embodiment of the utility model is shown. The parachute rocket launching device includes a parachute launching assembly 1 and a parachute shooting tube 2. The parachute shooting tube 2 is provided with a launching chamber 21. The parachute launching assembly 1 includes a launching body 11 and a connecting ring 12. The launching body 11 is slidably arranged in the launching chamber 21. The connecting ring 12 is rotatably connected to the launching body 11. The connecting ring 12 can be in a folded state when the launching body 11 is located in the launching chamber 21. The folded state is not the folding of the connecting ring 12 itself, but the state in which the free end of the connecting ring 12 leans against the launching body 11 when the connecting ring 12 rotates. The connecting ring 12 is used to connect the parachute adapter belt. When the launching body 11 slides away from the launching chamber 21, the connecting ring 12 can rotate to an extended state when subjected to the pulling force of the parachute adapter belt. In this embodiment, the connecting ring 12 can switch between a folded state and an extended state when rotating. When the connecting ring 12 is in a folded state ( Figure 2 As shown, the plane where the connecting ring 12 is located is perpendicular to the sliding direction of the launch body 11. At this time, when the launch body 11 slides into the launch cavity 21, the connecting ring 12 occupies a small space in the launch cavity 21, which is conducive to saving space in the launch cavity 21. The length of the launch body 11 does not need to be set very long, saving costs. When the parachute launching assembly 1 is ignited, the launch body 11 slides away from the launch cavity 21, and the parachute is straightened by the wind. The parachute is connected to the connecting ring 12 through its adapter belt, which exerts a pulling force on the connecting ring 12. The connecting ring 12 rotates to the extended state ( Figure 3 As shown in the figure), at this time, the plane where the connecting ring 12 is located is located at the central axis of the launching body 11, so that the pulling force of the parachute on the parachute launching assembly 1 tends to be uniform.

[0028] In one embodiment, see Figure 2The launch body 11 has two spaced connection ears 111, the connection ring 12 is U-shaped, and the two ends of the connection ring 12 are respectively rotated to connect the two connection ears 111, so that a connection groove 112 is formed between the connection ring 12 and the launch body 11, and the connection groove 112 is used for the parachute adapter belt to pass through and be installed on the connection ring 12, so as to facilitate the rapid connection of the parachute adapter belt. In this embodiment, a positioning groove can also be opened in the middle part of the connection ring 12, and the parachute adapter belt is tied to the positioning groove, so that the parachute launch assembly 1 can maintain balance to a greater extent when landing through the parachute.

[0029] In one embodiment, see Figure 2 The parachute launching assembly 1 further includes a first screw 13 and a second screw 14. The first screw 13 is provided with a screw hole. The first screw 13 passes through the connecting ear 111 and the connecting ring 12. The second screw 14 is threadedly connected to the screw hole to connect and install the connecting ring 12 with the connecting ear 111. After the first screw 13 and the second screw 14 are threadedly locked, they do not clamp the connecting ear 111 and the connecting ring 12, but only limit them so that they will not separate from each other. The connecting ear 111 and the connecting ring 12 can easily rotate relative to each other, so that the connecting ring 12 can smoothly rotate to the extended state under the pulling of the parachute adapter belt.

[0030] In one embodiment, the launch body 11 is provided with a storage cavity (not shown in the figure), and two connecting ears 111 are slidably connected to the launch body 11 and can slide into or out of the storage cavity when sliding. Before the parachute launching assembly 1 is launched, the two connecting ears 111 can be slid into the storage cavity for storage, and the connecting ring 12 at this time occupies less space in the launch cavity 21, further saving space in the launch cavity 21. When the parachute launching assembly 1 is ignited and launched, as the parachute adapter pulls the connecting ring 12, the connecting ring 12 drives the two connecting ears 111 to slide out of the storage cavity, and the connecting ring 12 is also in an extended state.

[0031] In one embodiment, see Figure 2 The two connecting ears 111 can also be connected to the launch body 11 by welding. In this embodiment, the launch body 11 has no storage cavity, and the space occupied by the launch cavity 21 can only be reduced by rotating the connecting ring 12 to a folded state.

[0032] In one embodiment, see Figure 1 and Figure 2The outer wall of the launch body 11 is provided with a positioning protrusion 113, and the cavity wall of the launch cavity 21 is provided with a slide groove 211, and the slide groove 211 is slidably engaged with the positioning protrusion 113. When the shooting umbrella launch assembly 1 is ignited and launched, the launch body 11 slides and rises along the slide groove 211 of the launch cavity 21 through the positioning protrusion 113. The slide groove 211 and the positioning protrusion 113 are slidably engaged and limited, so that the shooting umbrella launch assembly 1 rises more stably.

[0033] In one embodiment, see Figure 1 The outer wall of the launch body 11 is provided with a plurality of auxiliary grooves 114 along its circumference, and the cavity wall of the launch cavity 21 is correspondingly provided with a plurality of auxiliary rails 212 along its circumference, and each auxiliary rail 212 is slidably connected to the corresponding auxiliary groove 114. When the parachute launch assembly 1 is ignited and ascends, the launch body 11 slides and ascends along the auxiliary rails 212 through the auxiliary grooves 114, which can further improve the ascending stability of the parachute launch assembly 1.

[0034] In one embodiment, see Figure 4 The parachute launch assembly 1 further includes a fuel 15 and a jet component 16. The fuel 15 is disposed in a combustion chamber disposed in the launch body 11. The jet component 16 is connected to the launch body 11 and communicates with the combustion chamber. The high-pressure gas formed by the combustion of the fuel 15 in the combustion chamber can be ejected through the jet component 16 to generate a lifting force for the parachute launch assembly 1. In this embodiment, the fuel 15 is provided with a through combustion hole 151. The hole wall of the combustion hole 151 and the outer wall of the fuel 15 are coated with gunpowder to increase the combustion area of ​​the fuel 15. The fuel 15 can burn faster, thereby improving the lifting efficiency of the parachute launch assembly 1.

[0035] In one embodiment, see Figure 4 The number of the jet components 16 is multiple, and the multiple jet components 16 are evenly connected around the circumference of the launch body 11. In addition, the jet direction of the jet component 16 is set at an angle to the sliding direction of the launch body 11. Figure 4 The included angle formed by the jetting direction of the jetting member 16 and the sliding direction of the launching body 11 in the illustrated embodiment is 60°, which is beneficial to increase the ascending power of the parachute launching assembly 1.

[0036] In one embodiment, see Figure 1 The outer wall of the parachute tube 2 is provided with a plurality of mounting brackets 22, and the mounting brackets 22 are provided with a plurality of screw holes 221. The mounting brackets 22 can be fixed on the corresponding aircraft by screws through the screw holes, so as to facilitate disassembly and replacement. In other embodiments, the mounting brackets 22 can also be directly welded to the aircraft.

[0037] In order to better understand the present invention, the following Figures 1 to 4 The technical solution of the utility model is described in detail:

[0038] The parachute tube 2 of the utility model is fixedly installed on the aircraft. When the aircraft needs to use a parachute to land, the aircraft can be controlled to ignite the fuel 15 inside the launch body 11. When the fuel 15 burns, it drives the jet part 16 to produce jets, driving the launch body 11 to slide away from the parachute tube 2. The launch body 11 drives the parachute to open during the launch process. The parachute is also connected to the aircraft, so the parachute can assist the aircraft to land after opening. The main function of the parachute launch assembly 1 is to quickly release the parachute so that the parachute can assist the aircraft to land after opening.

[0039] After the parachute adapter belt is connected to the connecting ring 12, it is thrown upward from the exit of the parachute shooting tube 2 along the gap between the parachute shooting tube 2 and the launching body 11, and connected to the parachute in the parachute cabin of the aircraft. The connecting ring 12 located inside the parachute shooting tube 2 is in a folded state. When the aircraft ignites the fuel 15 to drive the launching body 11 to rise and separate from the parachute shooting tube 2, the connecting ring 12 pulls the parachute out of the parachute cabin. Under the air resistance of the parachute, the parachute drives the connecting ring 12 to rotate to an extended state through the adapter belt.

[0040] The specific implementation methods of the utility model described above do not constitute a limitation on the protection scope of the utility model. Any other corresponding changes and modifications made according to the technical concept of the utility model should be included in the protection scope of the claims of the utility model.
