Problems solved by technology

[0002] At present, the installation method of the hatch cover of small civilian drones is usually mainly screw fastening. The fastening method of this hatch cover requires the use of tools, which directly affects the rapidity of the system and makes the removal of the hatch cover longer.
In the process of debugging and field operations of UAVs, it is necessary to open the hatch cover frequently to replace and maintain batteries, check avionics equipment, and download flight data. The embedded thread of the body needs to be repaired; at the same time, this bolt connection method is inconvenient to disassemble and install, and special tools are required to fasten and disassemble the bolts. 3-5 minutes
[0003] The application advantage of UAV is that it is convenient, quick, safe and reliable compared with manned aircraft, but the existing connection method between the hatch cover and the fuselage is cumbersome to assemble and has insufficient reliability. The scope and prospect of man-machine application

Embodiment 1

[0030] see Figure 1-4 , the present invention provides a kind of unmanned aerial vehicle canopy fast locking device, comprising:

[0031] The hatch cover mounting seat 1 is installed on the hatch cover and is cylindrical; one end is open, the other end has an end cover 11, and the center of the end cover 11 has a hole for the pin shaft 21 to pass through. Between the end cover 11 and the pin shaft 21 For tight fit, it can prevent dust and short-term rainproof function;

[0032] The lock cylinder 2 includes a pin shaft 21 pierced in the hatch mounting seat 1, a spring 22 pierced on the pin shaft 21 and a lock pin 23 detachably mounted on the pin shaft 21, and the pin shaft 21 has a spring seat 24. The spring 22 is installed between the spring seat 24 and the lock pin 23; one end of the pin shaft 21 has a rotating head 21a for easy rotation, and the rotating head 21a extends outward from the hatch cover mounting seat 1, and the rotating head 21a is in the shape of a positive p...

Embodiment 2

[0039] see Figure 5-10 , on the basis of Embodiment 1, a limit groove 33 for limiting the rotation angle of the lock pin 23 is also provided on the end extending along the lock groove 32 on the fuselage mounting seat 3, and the cross section of the limit groove 33 includes a pin shaft 21 is fitted with a central hole 33a and two sectors 33b symmetrically distributed with respect to the center of the central hole, and the diameter of the sectors 33b is the same as the length of the lock pin 23 . The central angle of the sector 33b is between 60° and 120°, preferably 90°. A groove 3c for limiting the rotation of the lock pin 23 is provided on the end surface 3b extending along the lock groove on the body mount 3 , and the angle between the groove 3c and the lock groove 32 is 90 degrees.

[0040]Press down the pin shaft 21 and rotate it 90° clockwise, the quick lock is locked, and the pin shaft 21 is turned 90° counterclockwise to pop up, and the quick lock is opened.
