[0024] The specific embodiments of the utility model will be described in detail below with reference to the drawings.

[0025] As shown in Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 A quick-release expansion device, comprising a connecting base 1 and two groups of connecting assemblies, the two groups of connecting assemblies are respectively used for detachably and fixedly connecting the connecting base 1 and the fuselage of the unmanned aerial vehicle and the load equipment, each group of connecting assemblies comprises at least one connecting piece, and each connecting piece comprises:

[0026] A connecting plate 2 is fixedly installed on the fuselage or the connecting base 1, and a connecting sliding groove 3 is arranged on the connecting plate 2;

[0027] A connecting sliding block 4 is fixedly installed on the connecting base 1 or the load equipment, and the connecting sliding block 4 is slidably installed in the connecting sliding groove 3;

[0028] A locking piece is used for controlling whether the connecting sliding block 4 and the connecting sliding groove 3 slide or not, when the locking piece is locked, the connecting sliding block 4 and the connecting sliding groove 3 are controlled to be in a relatively stationary state all the time, and when the locking piece is released, the connecting sliding block 4 and the connecting sliding groove 3 are relatively slidable.

[0029] The inner recesses of the two ends of the connecting slide groove 3 of the connecting plate 2 form support grooves 5, and the two ends of the connecting slide block 4 are respectively located in the support grooves 5.

[0030] The locking member comprises at least one locking rod 6 and at least one first elastic member. The locking rod 6 is rotatably installed on the connecting plate 2, and the two ends of the first elastic member respectively act on the locking rod 6 and the connecting plate 2. The first elastic member generates an acting force on the locking rod 6, so that the first end of the locking rod 6 is subjected to an acting force in the direction towards the central axis of the connecting plate 2. At least one mounting groove 7 is arranged on the connecting plate 2, and the first end of one locking rod 6 is located in one mounting groove 7. The mounting groove 7 is in communication with the middle part of the support groove 5. At least one locking groove 8 is arranged on the two side faces of the connecting slide block 4. The two ends of the two side faces of the connecting slide block 4 are both guiding arc structures 9. When the locking member is locked, the first side face 10 and the second side face 11 of the first end of the locking rod 6 are respectively in extrusion contact with the third side face 12 and the fourth side face 13 of the locking groove 8.

[0031] The first elastic member is a torsion spring.

[0032] When the connecting assembly is used to fix the connecting base 1 and the fuselage or to fix the connecting base 1 and the load equipment, an acting force is applied to the connecting slide block 4 to make the connecting slide block 4 installed in the connecting groove. The extrusion acting force is generated between the support groove 5 and the slide block. When the connecting slide block 4 is slidably installed in the connecting slide groove 3, the guiding arc structure 9 of the connecting slide block 4 generates an extrusion force on the locking rod 6 in the mounting groove 7. The first end of the locking rod 6 rotates in the direction away from the central axis of the connecting plate 2. At this time, the first elastic member stores energy. When the connecting slide block 4 is moved to the position, the locking groove 8 is located at the position of the mounting groove 7. At this time, the first end of the locking rod 6 loses the extrusion acting force of the connecting slide block 4. The first elastic member releases energy. The first end of the locking rod 6 rotates in the direction towards the central axis of the connecting plate 2. The first side face 10 and the second side face 11 of the first end of the locking rod 6 are respectively in extrusion contact with the third side face 12 and the fourth side face 13 of the locking groove 8. The locking rod 6 controls the connecting slide block 4 and the connecting slide groove 3 to be in a relatively static state, so as to achieve the locking purpose. The guiding arc structure 9 of the connecting slide block 4 realizes the guiding action when the connecting slide block 4 enters the connecting slide groove 3 and contacts the locking rod 6, so as to facilitate the installation and connection between the connecting slide block 4 and the connecting slide groove 3. When the connecting slide block 4 is disassembled, an acting force is applied to the second end of the locking rod 6. The first end of the locking rod 6 rotates in the direction away from the central axis of the connecting plate 2. At this time, the connecting slide block 4 and the connecting slide groove 3 are in a relatively slidable state. An acting force is applied to the connecting slide block 4, so that the connecting slide block 4 and the connecting slide groove 3 can be separated. The connecting base 1 and the connecting assembly are used as the bridge for connecting the fuselage and the load equipment. Different load equipment can be replaced without changing the fuselage, so as to realize one machine with multiple uses.

[0033] The quick-release expansion device further comprises a first support 14, a second support 15, a first locking tongue 16, a second locking tongue 17, two locking hooks 18 and a second elastic member, the first end of the first support 14 and the first end of the second support 15 are fixedly installed on the connecting base 1, the first end of the second locking tongue 17 is fixedly installed on the second support 15, the first locking tongue 16 is rotatably installed on the first support 14, the two locking hooks 18 are respectively fixedly installed on the spray rod 19 for unmanned aerial vehicle fire extinguishing, the two locking hooks 18 are respectively locked with the first locking tongue 16 and the second locking tongue 17, when the directions of the two locking hooks 18 are opposite, the second elastic member generates an acting force on the first locking tongue 16, so that the second end of the first locking tongue 16 is subjected to the acting force in the direction towards the second locking tongue 17; when the directions of the two locking hooks 18 are opposite, the second elastic member generates an acting force on the first locking tongue 16, so that the second end of the first locking tongue 16 is subjected to the acting force in the direction away from the second locking tongue 17.

[0034] The second elastic member is a torsion spring.

[0035] When the spray rod 19 is installed, an acting force in the direction towards the connecting base 1 is applied to the spray rod 19, when the two locking hooks 18 respectively contact and generate extrusion forces on the first locking tongue 16 and the second locking tongue 17, the first locking tongue 16 is rotated under the action of the locking hook 18, in this embodiment, the first locking tongue 16 is rotated in the direction away from the second locking tongue 17, the distance between the first locking tongue 16 and the second locking tongue 17 is increased, in this process, the second elastic member stores energy, when the locking hook 18 passes the height of the first locking tongue 16 and the second locking tongue 17, the first locking tongue 16 loses the extrusion force of the locking hook 18, the second elastic member releases energy, the first locking tongue 16 is rotated in the direction towards the second locking tongue 17, so that the two locking hooks 18 are locked by the first locking tongue 16 and the second locking tongue 17, the fixing of the spray rod 19 is completed, when the spray rod 19 is disassembled, only an acting force in the direction away from the second locking tongue 17 needs to be applied to the first locking tongue 16, so that the distance between the first locking tongue 16 and the second locking tongue 17 is increased, at this time, the spray rod 19 can be separated from the connecting base 1, the whole process of installation and disassembly is simple.

[0036] The technical scheme of the utility model is not limited to the limitation of the above-mentioned specific embodiments, any technical deformation made according to the technical scheme of the utility model falls within the protection scope of the utility model.
