Description

Unmanned aerial vehicle quick detach formula screw guard circle Technical Field The utility model relates to the technical field of unmanned aerial vehicle accessories, in particular to an unmanned aerial vehicle quick-dismantling type propeller protection ring. Background In prior art system, for guarantee unmanned aerial vehicle paddle operation safety, common practice is in the outside installation guard circle of paddle bottom, when unmanned aerial vehicle flies in complex environment, like low altitude passes through the tree, is close to under the scene such as building, the guard circle can effectively avoid paddle and external object unexpected collision to reduce the impaired risk of paddle, guarantee unmanned aerial vehicle flight stability and security, promoted unmanned aerial vehicle operation reliability to a certain extent. However, the outside of the top of the blade often lacks corresponding quick detach formula guard circle, in unmanned aerial vehicle flight process, the outside of the top of the blade faces collision risk equally, if fly in narrow space, the top of the blade is easy to contact with the barrier above, and even if there is the safeguard measure to the outside of the top of the blade, mostly adopt integral type structure guard circle, this kind of integral type structure can provide certain protection, but wholly be difficult to realize quick detach, in actual use, if the guard circle is impaired needs to be changed, or when need adjusting protection device because of different operation scenes, integral type structure needs to consume a large amount of time and energy dismantlement, seriously influence unmanned aerial vehicle availability factor and maintenance convenience, simultaneously, the guard circle that can't dismantle fast also can occupy great space in unmanned aerial vehicle accomodate, the transportation, bring a great deal of inconvenience. Disclosure of utility model Based on the above, the utility model aims to provide a quick-dismantling propeller protection ring of an unmanned aerial vehicle so as to solve the technical problems in the background art. In order to achieve the purpose, the utility model provides the technical scheme that the unmanned aerial vehicle quick-dismantling type propeller protection ring comprises a flight arm and a blade module arranged at the top of the tail end of the flight arm, wherein the bottom and the top of the flight arm are connected with a bottom cover module and a top cover module which are positioned at the bottom and the top of the blade module; The bottom cover module consists of a bottom protection cover with a first plugboard fixed on one side, the top cover module consists of a top protection cover with a second plugboard fixed on one side, a locking mechanism is arranged in the flying arm and comprises a bottom plughole and a top plughole which are matched with the first plugboard and the second plugboard, the locking mechanism also comprises a locking plate which is positioned in the flying arm and is in sliding connection, and the locking plate is inserted into the first plugboard and the second plugboard after sliding, so that the bottom protection cover and the top protection cover are stably connected; A first through hole and a second through hole which are matched with the locking plate are respectively formed in the first plugboard and the second plugboard, and the tail end of the locking plate is movably connected with a turnover lock catch which is manually clamped and connected with the flying arm; The bottom cover module further comprises two groups of connecting rods extending to the inside of the flying arm, connecting holes matched with the two groups of connecting rods are formed in the inside of the flying arm, a locking rod penetrating through the two groups of connecting rods is fixed on one side of the locking plate, and bolt holes matched with the locking rod are formed in the inside of the two groups of connecting rods; Through setting up end cover module and top cover module in flight arm bottom and top, end cover module and top cover module cooperate with the inside locking mechanical system of flight arm through first picture peg and second picture peg respectively, inside first picture peg, the second picture peg of inserting behind locking mechanical locking plate slip, the latch lever runs through the bolt hole of connecting rod simultaneously, the rethread upset hasp locking, the quick assembly disassembly and stable connection of safety cover and flight arm has been realized, this kind of structural design not only can form effective protection to the top and the bottom of paddle module, the paddle is damaged with external object collision when avoiding unmanned aerial vehicle to fly in the complex environment, guarantee flight stability and security, still solved traditional integral type guard circle be difficult to quick detach, maintenance inconvenience and accomodate the big prob
