Detailed Description

The present invention will be further described with reference to the accompanying drawings and the detailed description, and it should be noted that the embodiments or technical features described below can be arbitrarily combined to form a new embodiment without conflict.

Fig. 1 shows that the utility model discloses unmanned aerial vehicle wing body connects the exploded view of lock. This unmanned aerial vehicle wing body joint lock includes lockpin 1, front shroud 2, back shroud 5 and is located the canceling release mechanical system between front shroud 2 and the back shroud 5.

Fig. 2 is a schematic structural diagram of the reset mechanism. This canceling release mechanical system includes mount 7, remove frame 3, cylindric lock 4 and spring 6, the assembly groove has been seted up to mount 7, it assembles in this assembly groove to remove frame 3, the spacing groove has been seted up to the both sides in this assembly groove, the both sides protrusion that removes frame 3 has can follow gliding stopper from top to bottom in the spacing groove, spring 6 assembles between removing frame 3 and mount 7, preceding lockhole has been seted up to preceding apron 2, the back lockhole has been seted up to back shroud 5, remove frame 3 and seted up the lockpin through-hole, 4 assembles in the lockpin through-hole of cylindric lock, and be used for with 1 joint of lockpin.
