It should be noted that, in the following embodiments, the "first" and "second" do not represent an absolute distinction relationship in structure and/or function, nor represent a sequential execution order, but merely for convenience of description.

As shown in fig. 1 to 7, the utility model provides a quick release lock for an unmanned aerial vehicle, which comprises a first locker 2, a second locker 3 matched with the first locker 2, a rotary connecting block 4 rotatably connected with the second locker 3, a main lock catch 1 rotatably connected with the rotary connecting block 4 and used for locking the first locker 2 and the second locker 3 together, and a locking mechanism arranged on the main lock catch 1 and used for locking the second locker 3.

Specifically, as shown in fig. 1 to 7, the locking mechanism includes an auxiliary lock catch 7 rotatably disposed on the main lock catch 1, a pressing plate 6 connected to the auxiliary lock catch 7, and an elastic member 9 disposed between the pressing plate 6 and the main lock catch 1, and the second locker 3 has a first catching groove into which a first protrusion disposed at an end of the auxiliary lock catch 7 is fitted. The one end on the length direction of supplementary hasp 7 passes through hinge pin 5 with the one end of rotating connecting block 4 to rotate to be connected, the other end of rotating connecting block 4 and the one end of second locking ware 3 are passed through another hinge pin 5 and are rotated and be connected, first draw-in groove is the rectangle recess that sets up on this end terminal surface of second locking ware 3, the length direction of first draw-in groove is parallel with the rotation center line who rotates connecting block 4 and main hasp 1, the other end terminal surface of second locking ware 3 contacts with the one end terminal surface of first locking ware 2, the terminal surface that first locking ware 2 and second locking ware 3 contacted is the plane that is parallel with the rotation center line who rotates connecting block 4 and main hasp 1.

As shown in fig. 1 to 7, a through hole is formed in the main lock catch 1 for the auxiliary lock catch 7 to pass through, the pressing plate 6 is located outside the main lock catch 1, the pressing plate 6 is connected with one end of the auxiliary lock catch 7 in the length direction through a screw 8, and the first protruding block is arranged at the other end of the auxiliary lock catch 7 in the length direction. The elastic element 9 is a cylindrical spiral spring and is a compression spring, the elastic element 9 selects springs made of different materials according to the use temperature, the elastic element 9 is sleeved on the auxiliary lock catch 7, one end of the elastic element 9 is abutted to the pressing plate 6, and the other end of the elastic element 9 is abutted to the main lock catch 1. Through the effect of the elastic force that elastic element 9 applyed, when using, compress tightly auxiliary lock catch 7 on main hasp 1, during first arch is embedded into first draw-in groove all the time to can avoid the condition that quick detach lock opened under vibrations.
