[0023] The technical solutions in this embodiment will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0024] like Figures 1-6 As shown, this embodiment discloses a quick-release structure, including a flight platform 1 and a hoisting assembly 2. The flight platform 1 includes a frame 11, which is a rectangular frame with two long sides and two short sides. Multiple locking assemblies 14 are installed on the sides of the frame 11. There are four locking assemblies 14, which are distributed in pairs on the long sides of the frame 11. The hoisting assembly 2 includes a bracket 21, which is formed by bending a circular tube. Multiple connecting brackets 22 corresponding to the locking assemblies 14 are installed on the upper end of the bracket 21.

[0025] like Figures 3-5As shown, the locking assembly 14 includes a fixed plate 141, a fastener 142, and a connecting block 143. The fixed plate 141 is fixedly installed on the frame 11 by bolts. One end of the connecting block 143 is rotatably connected to the fixed plate 141. The fixed plate 141 includes two mounting plates 1412 and a first rotating shaft 1413. The mounting plates 1412 extend toward the fastener 142. The first rotating shaft 1413 is installed on the two mounting plates 1412. The connecting block 143 is rotatably connected to the first rotating shaft 1413. The fastener 142 includes a plate 1421, two side plates 1422, and a second rotating shaft 1423. The side plates 1422 extend toward the fixed plate 141. The second rotating shaft 1423 is installed on the two side plates 1422. The other end of the connecting block 143 is rotatably connected to the fastener 142. The connecting block 143 is rotatably connected to the second rotating shaft 1423, so that the fastener 142 can move up and down while approaching the fixed plate 141.

[0026] The lower end of the fastener 142 is provided with a hanging rod 145, which is installed between two side plates 1422. The connecting frame 22 includes a hook 221, which is located on the outside of the connecting frame 22. The hook 221 includes a hook groove 2211, the opening of which faces downward. When the fastener 142 moves up and down closer to the fixing plate 141, the hanging rod 145 enters the hook groove 2211 from the opening. When the fastener 142 reaches the highest position and abuts against the fixing plate 141, the hanging rod 145 abuts against the hook groove 2211.

[0027] A snap fastener 144 is installed on the upper end of the fastener 142. The snap fastener 144 is rotatably installed on the fastener 142 and installed between the two side plates 1422. The upper end of the fixing plate 141 is provided with a first buckle part 1411 that engages with the snap fastener 144. The snap fastener 144 is supported by a torsion spring and includes a second buckle part 1441. When the fastener 142 reaches the highest position and abuts against the fixing plate 141, the second buckle part 1441 of the snap fastener 144 engages with the first buckle part 1411, thus fastening and fixing the fastener 142 and the fixing plate 141. The hanging rod 145 remains against the hook groove 2211, thereby fixing the frame 11 and the bracket 21. The vertical downward pulling force of the hoisting assembly 2 on the flight platform 1 is locked by the horizontal snap fastener 144, resulting in a robust structure.

[0028] like Figure 2 , Figure 5As shown, this embodiment includes a first state and a second state. In the first state, the second buckle 1441 is fastened to the first buckle 1411, the hanging rod 145 abuts against the hook groove 2211, and the frame 11 is fixedly connected to the bracket 21. In the second state, the first buckle 1411 disengages from the second buckle 1441, the hanging rod 145 can leave the hook groove 2211, and the frame 11 can be separated from the bracket 21. From the first state to the second state, it is only necessary to press the snap button 144 to make the snap button 144 overcome the force of the torsion spring, the first buckle 1411 disengages from the second buckle 1441, the fastener 142 and the fixing plate 141 are unlocked, the hanging rod 145 leaves the hook groove 2211, and the flight platform 1 and the hoisting assembly 2 can be separated. Disassembly and installation are very quick and convenient.

[0029] like Figures 2-5 As shown, more preferably, the fixing plate 141 is provided with a first limiting block 1414, which is located on the side of the fixing plate 141 facing the fastener 142 and extends in the direction of the fastener 142. The connecting block 143 is provided with a third limiting block 1432, which is located at the end of the connecting block 143 near the fixing plate 141. The first limiting block 1414 is located above the rotation direction of the third limiting block 1432. The first limiting block 1414 and the third limiting block 1432 abut against each other and can limit the rotation angle of the connecting block 143 in the second state to prevent the fastener 142 from becoming too loose.

[0030] Similarly, the connecting block 143 includes a second limiting block 1431, which is located at one end of the connecting block 143 near the fastener 142. The second limiting block 1431 can abut against the inner wall of the fastener 142. If the rotation angle of the fastener 142 is too large, the movement angle of the fastener 142 is limited to prevent the fastener 142 and the fixing plate 141 from becoming too loose.

[0031] like Figure 2 As shown, the fixing plate 141 includes two support blocks 1415. The two support blocks 1415 are located on the side of the fixing plate 141 facing the fastener 142. In the first state, one support block 1415 abuts against one side plate 1422. Since there is a gap between the side plate 1422 and the fixing plate 141 after the fastener 142 is fastened to the fixing plate 141, there is no support on both sides of the fastener 142. The support blocks 1415 can support the side plate 1422 to make the fastener 142 more stable.

[0032] The connecting frame 22 includes a positioning seat 222, which has a positioning surface 2221. The positioning surface 2221 is an arc surface and abuts against the outer wall of the bracket 21. The bracket 21 has a circular tubular structure and a connecting shell is installed at the upper end of the bracket 21. The positioning seat 222 and the connecting shell cover and fix the bracket 21 in the inside, so that the positioning seat 222 can better connect with the bracket 21.

[0033] like Figure 6 The image shows the drone used in this embodiment. The flight platform 1 and the hoisting component 2 can be quickly disassembled and installed, which facilitates the disassembly of the drone and the replacement of the hoisting component 2.

[0034] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
