[0024] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs; the terminology used herein in the specification of the application is for the purpose of describing particular embodiments only and is not intended to be limiting of the application; the terms "comprising" and "having," and any variations thereof, in the specification, claims, and foregoing drawings of this application are intended to cover non-exclusive inclusion. The terms "first," "second," etc., in the specification, claims, or foregoing drawings of this application are used to distinguish different objects, not to describe a particular order.

[0025] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0026] This utility model embodiment provides a drone propeller protective cover, such as Figures 1-4 As shown, the device includes a body 1, with frames 2 mounted on the sides of the body 1. Four sets of frames 2 are arranged in a circular array on the four sides of the body 1. Blades 3 are mounted on the top of the frames 2. An mounting plate 4 is mounted at the center of the upper surface of the body 1. A support frame 5 is mounted on the top of the mounting plate 4. A fixing frame 6 is mounted on the outside of the support frame 5. Connecting plates 7 are mounted on the sides of the fixing frame 6. Four sets of connecting plates 7 are arranged in a circular array on the sides of the fixing frame 6. A sleeve plate 8 is connected to one end of the connecting plate 7 away from the fixing frame 6, and a protective ring 9 is connected to the other end of the sleeve plate 8. The four sets of protective rings 9 are located outside the four sets of blades 3. The support frame 5 is rectangular. A rectangular groove is provided on the lower side of the fixing frame 6, allowing the fixing frame 6 to slide onto the outside of the support frame 5. A connecting rod 10 is rotatably mounted on the top of the fixing frame 6. Threads are provided on the lower side of the connecting rod 10. A threaded groove matching the thread on the surface of the connecting rod 10 is provided on the top of the support frame 5. The connecting rod 10 is threadedly connected to the support frame 5. This UAV protects the entire propeller by setting protective rings 9 on the outside of the blades 3. Four sets of protective rings 9 are installed on the four sides of the fixed frame 6. The protective rings 9 cover the blades 3 completely, thus protecting the blades 3 in all directions. Compared with traditional protective mechanisms, this is more comprehensive and has a better protective effect. At the same time, the four sets of protective rings 9 and the fixed frame 6 are integrated. The fixed frame 6 can be controlled to move up and down via the connecting rod 10. Therefore, the height of the protective rings 9 can be adjusted by rotating the connecting rod 10. At the same time, the four sets of protective rings 9 can be pulled out and removed from the outside of the blades 3, making subsequent propeller maintenance more convenient. This device can adjust the height of the four sets of protective rings 9 synchronously by setting the fixed frame 6 and the support frame 5. Therefore, it is applicable to propeller UAVs with different heights. It also enables quick installation and removal of the protective rings 9, making subsequent propeller maintenance more convenient and faster.

[0027] A plate 11 is installed on the side of the protective ring 9. A slot adapted to the plate 11 is opened on the side of the sleeve plate 8. A groove is opened at the front end of the sleeve plate 8, and a pull rod 12 is slidably inserted into the groove. A locking block 13 is connected to the inner end of the pull rod 12. A slot adapted to the locking block 13 is opened on the upper surface of the plate 11. A spring 14 is sleeved on the outside of the pull rod 12. With the plate 11 and locking block 13, the protective ring 9 is installed on the side of the sleeve plate 8 through the plate 11. The locking block 13 in the sleeve plate 8 is locked into the top of the plate 11 under the elastic force of the spring 14, thereby realizing the limiting and fixing of the plate 11. This setting allows the protective ring 9 to be removed and installed separately from the sleeve plate 8, so as to facilitate the replacement of the damaged protective ring 9. At the same time, this installation method is simple and convenient, making the removal and installation steps of the protective ring 9 easier.

[0028] The outer side of the locking block 13 is set as a slope. This setting allows the insert plate 11 to push the locking block 13 upward when it is pushed in, thereby further simplifying the installation steps of the protective ring 9.

[0029] The sleeve plate 8 is slidably sleeved on the outside of the connecting plate 7. A fixing pin 15 is installed on the upper end of the sleeve plate 8. The fixing pin 15 is threadedly connected to the sleeve plate 8. The upper surface of the connecting plate 7 is provided with positioning grooves that are adapted to the fixing pin 15 at equal intervals. By setting the fixing pin 15, the sleeve plate 8 and the connecting plate 7 are slidably installed and fixed by the fixing pin 15. This setting can adjust the distance between the protective ring 9 and the fixing frame 6. This setting can make the protective device suitable for drones of different sizes.

[0030] The connecting plate 7 is mounted on the side of the fixing frame 6 via the fixing block 20. The fixing block 20 is fixed to the side of the fixing frame 6 by bolts 16. The side of the fixing frame 6 has eight sets of mounting slots that are compatible with the fixing block 20 and are distributed in a circumferential array. By setting the fixing block 20, the connecting plate 7 and the fixing frame 6 are fixed together by the fixing block 20. This setting allows the connecting plate 7 and the fixing frame 6 to be detachable, thereby reducing the cost of replacing parts later. By setting eight sets of mounting slots, the device can be used for various multi-wing UAVs.

[0031] The mounting plate 4 has sliding grooves on both the left and right sides, and a limiting plate 17 is slidably embedded in the sliding grooves. A fastening bracket 18 is connected to the outside of the limiting plate 17. The fastening bracket 18 is installed on the top of the frame 2 by fastening screws 19. By setting the fastening bracket 18, the fastening bracket 18 is slidably installed on both sides of the mounting plate 4 through the limiting plate 17. The fastening bracket 18 can be pushed and pulled from both sides of the mounting plate 4, thereby adjusting the installation position of the fastening screws 19, and thus making it suitable for different drones.

[0032] The fastening bracket 18 is C-shaped, and the surface of the fastening bracket 18 is provided with circular positioning holes that are compatible with the fastening screws 19. By opening multiple positioning holes on the surface of the fastening bracket 18, the installation flexibility of the mounting plate 4 can be further improved, and the applicability of the device can be further improved.

[0033] The protective ring 9 has rectangular slots arranged in a circumferential array on its side. By opening slots on the side of the protective ring 9, the overall weight of the protective ring 9 can be reduced, making the device lighter and thus reducing the load on the drone.
