DETAILED DESCRIPTION
[0024] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of the utility model.
[0025] Embodiment 1: a quick-release type unmanned aerial vehicle propeller, please refer to Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 6 、 Figure 7 And Figure 8 , including connecting plate 1, motor 2, connecting shaft 3, fixed sleeve 4 and spiral blade 5, the top of connecting plate 1 is installed with motor 2, the output shaft of motor 2 is connected with connecting shaft 3 through coupling, the top of connecting shaft 3 is covered with fixed sleeve 4, and the left and right sides of fixed sleeve 4 are fixedly connected with spiral blade 5, the left and right sides in fixed sleeve 4 are fixedly connected with contact block 6, two ball 8 are slidably arranged in connecting shaft 3, ball 8 is connected with contact block 6, spring 7 is connected between ball 8 and connecting shaft 3, two rubber plates 9 are embeddedly arranged in connecting shaft 3, rubber plate 9 increases the friction between contact block 6 and connecting shaft 3, avoids the rotation of fixed sleeve 4 due to external force factor, and then makes contact block 6 move, connecting shaft 3 is provided with first magnetic block 17, the inner top of fixed sleeve 4 is provided with second magnetic block 18, second magnetic block 18 adsorbs first magnetic block 17, thereby providing additional locking force, ensuring that fixed sleeve 4 does not accidentally loosen.
[0026] When installing the propeller, first, place the retaining sleeve 4 on top of the connecting shaft 3. Then, rotate the retaining sleeve 4 to cause the contact block 6 to press the retaining ball 8 upward. At this time, the spring 7 is compressed. Continue rotating the retaining sleeve 4 until the contact block 6 moves to the appropriate position. At this point, the retaining ball 8 is no longer compressed, and the spring 7 returns to its original state, pushing the retaining ball 8 downward so that the retaining ball 8 engages with the contact block 6, thus completing the propeller installation. When disassembling the propeller, rotate the retaining sleeve 4 in the opposite direction to cause the contact block 6 to press the retaining ball 8 again. At this time, the retaining ball 8 moves upward along the arc surface inside the contact block 6, thus disengaging the retaining ball 8 from the contact block 6. Then, pull the retaining sleeve 4 upward to complete the disassembly of the propeller, achieving quick disassembly and facilitating maintenance or replacement.
[0027] Example 2: Based on Example 1, please refer to... Figure 4 and Figure 5 Connecting blocks 10 are slidably installed on both the left and right sides of the lower end of the connecting shaft 3. A wedge block 11 is fixedly connected to the inner side of the connecting block 10. Two locking rods 12 are slidably installed inside the connecting shaft 3. The locking rods 12 are engaged with the contact block 6. A gravity plate 13 is fixedly connected to the bottom of the locking rod 12. The bottom of the gravity plate 13 is close to the top of the wedge block 11. Anti-loss ropes 19 are connected to both the front and rear sides of the connecting shaft 3. The end of the anti-loss rope 19 away from the connecting shaft 3 is connected to the connecting block 10 to prevent the connecting block 10 from being lost during the disassembly of the propeller.
[0028] After the propeller is installed, move the connecting block 10 to the left and right sides of the connecting shaft 3 and push the connecting block 10 inward so that the wedge block 11 is inserted into the connecting shaft 3. During this process, the wedge block 11 squeezes the locking rod 12 upward so that the locking rod 12 engages with the contact block 6, thereby further fixing the fixing sleeve 4 and ensuring that the fixing sleeve 4 will not fall off.
[0029] Please see Figure 1 , Figure 6 and Figure 7 Two isolation plates 14 are snapped onto the outside of the connecting plate 1. A ventilation opening 15 for heat dissipation is provided in the middle of the outer side of the isolation plate 14. A protective rod 16 is fixedly connected to the upper part of the outer side of the isolation plate 14. A handle 20 is fixedly connected to the outer side of the isolation plate 14, which makes it easy to pick up the isolation plate 14.
[0030] Before using the propeller, move the isolation plate 14 to the left and right sides of the connecting plate 1 and push the isolation plate 14 to engage with the connecting plate 1, thereby fixing the isolation plate 14 and allowing the protective rod 16 to surround the propeller blade 5. When the drone is in flight, the protective rod 16 effectively protects the propeller blade 5, preventing the propeller blade 5 from accidentally touching external objects and ensuring the safety and stability of the flight.
