When the lock is automatically disassembled and locked, the distance between the lower part of the trigger rod 17 positioned between the two clamping arms 11 and the bottom of the clamping arm 11 is 5 cm, and the vertical movement of the trigger rod 17 does not influence the clamping fixation or release of the clamping arm 11 to the carried object.
The body of rod of the 17 both sides of trigger bar is vertical downwards, and length exceedes the height of carrying article, guarantees that unmanned aerial vehicle flight or descending in-process trigger bar 17 at first contact platform face, under the action of gravity of automatic disassembly lock and carrying thing, trigger bar 17 can relative automatic disassembly lock jack-up lock core 3 that makes progress to open automatic disassembly lock, realize unmanned aerial vehicle and the automation of carrying the thing and break away from.
When the unmanned aerial vehicle is used, the lifting ring 18 of the automatic dismounting lock is connected with the lower part of the unmanned aerial vehicle through the lifting rope 24, then the automatic dismounting lock is taken up and vertically placed, and at the moment, the upper core, the lower core and the trigger rod naturally droop; then, the well-adjusted positions of the loaded objects are placed under the trigger rod between the two clamping arms 11 and do not contact with the trigger rod, the locking arms 2 are pushed from two sides to the middle, when the left positioning hole 13 and the right positioning hole 13 are aligned, the upper core falls into the positioning holes 13, the locking arms are automatically locked under the elastic force provided by the springs 14, and at the moment, the two clamping arms 11 clamp and fix the loaded objects. Unmanned aerial vehicle takes off, when transporting the carrying thing and reacing target platform or unmanned aerial vehicle carrying thing touches the ground under the unexpected condition that unmanned aerial vehicle flight unstability leads to, because the length of trigger bar is greater than the height of carrying thing, the trigger bar at first contacts platform ground, under automatic dismantlement lock self action of gravity, the relative lock body upward movement of core in lower core promotion, realize then that the automation of automatic dismantlement lock is opened, carrying thing breaks away from with unmanned aerial vehicle safety, unmanned aerial vehicle can fly away from safely.
According to the invention, the automatic dismounting lock can be automatically opened when the unmanned aerial vehicle carrying equipment or articles touch the ground or the platform, so that the unmanned aerial vehicle carrying equipment has an automatic unlocking and separating function, and the safety of the suspension equipment and the unmanned aerial vehicle is ensured.
Example two
As shown in fig. 7, the structure of the present embodiment is substantially the same as that of the first embodiment, and the difference is that: the tail end of the trigger rod 17 is split into a plurality of supporting rods, the bottom of each supporting rod is provided with the ground feet 22, the trigger rod 17 can fall to the ground after contacting the platform and is more stable, the trigger rod can stand on the platform, and the risk that the trigger rod 17 and carrying equipment fall down or fall is reduced.
EXAMPLE III
As shown in fig. 8, the structure of the present embodiment is substantially the same as that of the first embodiment, and the difference is that: the lower extreme of centre gripping arm 11 sets up two fixed orificess 23, and fixed orificess 23 can carry more firmly with the better cooperation of the thing body of carrying that has shorter round pin axle, prevents to drop owing to the centre gripping is not tight to lead to carrying the thing accident.
Example four
As shown in fig. 9, the structure of the present embodiment is substantially the same as that of the first embodiment, and the difference is that: the two positioning arms 10 are respectively provided with three positioning holes 13, and the upper core 15 simultaneously penetrates through different positioning hole combinations to realize different clamping distances between the two clamping arms 11 during locking, so that the automatic lock can clamp objects with different thicknesses or widths, and the similar machine types can carry different goods or equipment.
EXAMPLE five
As shown in fig. 10, the structure of the present embodiment is substantially the same as that of the first embodiment, and the difference is that: the rubber pad 25 is arranged at the lower end of the clamping arm 11, the rubber pad 25 is elastic, the carried objects can be protected, meanwhile, the rubber pad 25 can increase friction force, and clamping is firmer and safer.
Finally, the above embodiments are only used for illustrating the technical solutions of the present invention and not for limiting, and other modifications or equivalent substitutions made by the technical solutions of the present invention by those of ordinary skill in the art should be covered within the scope of the claims of the present invention as long as they do not depart from the spirit and scope of the technical solutions of the present invention.
