Fig. 1 shows a connection locking device according to the invention, installed in a drone, for connecting and fixing the different components of the drone to its fuselage, forming a whole. The connection locking device, as shown in fig. 2, includes: the locking wrench swing arm 1 is provided to rotate about a rotation axis in the middle thereof between a locking position on the lower side and an unlocking position on the upper side. Still include tail locking connecting rod 3, its one end with locking spanner rocking arm 1 is connected, and tail locking locating pin 5 is connected to the other end locking spanner rocking arm 1 from top to bottom, by the in-process that the unblock position rotated to latched position, tail locking connecting rod 3 by locking spanner rocking arm 1 promotes, makes tail locking locating pin 5 inserts in the multi-functional locating pin bush 8 of tail end that is used for fixed tail. Correspondingly, aiming at the wings of the unmanned aerial vehicle, the wing locking connecting rod 4 is further arranged, one end of the wing locking connecting rod is connected with the locking wrench rocker arm 1, the other end of the wing locking connecting rod is connected with the wing locking positioning pin 6, and in the process that the locking wrench rocker arm 1 rotates from the unlocking position to the locking position, the wing locking connecting rod 4 is pushed by the locking wrench rocker arm 1, so that the wing locking positioning pin 6 is inserted into a wing end multifunctional positioning pin sleeve 7 for fixing the wings.

Specifically, the locking wrench rocker arm 1, the locking wrench 2, the tail locking connecting rod 3, the wing locking connecting rod 4, the tail locking positioning pin 5 and the wing locking positioning pin 6 jointly form a set of two-mode locking system. Locking spanner 2, it includes operation end and link, the link is connected with the one end of keeping away from the pivot on the locking spanner rocking arm 1, the operation end is in outstanding outside the unmanned aerial vehicle shell when locking spanner rocking arm 1 is located the unblock position locking spanner rocking arm 1 is located shrink in when the locking position within the unmanned aerial vehicle shell. The locking wrench 2 drives the tail locking connecting rod 3 and the wing locking connecting rod 4 to move simultaneously, so that the tail locking positioning pin 5, the wing locking positioning pin 6 and the tail multifunctional positioning pin sleeve 7 at the wing end are sleeved in the hole of the tail multifunctional positioning pin sleeve 8, and the locking or unlocking action is completed.

Referring to fig. 4 or 5, in the locked state, the locking wrench is moved to the lowermost position. The locking spanner drives the tail locking connecting rod 3 or the wing locking connecting rod 4 downwards and leftwards to push the plug pin to be inserted into the pin sleeve to realize fixed connection.

Unmanned aerial vehicle's fuselage and tail set up first tail connecting pipe and second tail connecting pipe respectively, first tail connecting pipe and second tail connecting pipe are in nested each other when the tail is in latched position, tail end multifunctional locating pin cover 8 runs through the nested position of first tail connecting pipe and second tail connecting pipe is fixed the tail is in latched position.

The multifunctional positioning pin bushing 7 at the wing end of the unmanned aerial vehicle penetrates through the connecting end face between the wing and the body of the unmanned aerial vehicle. The positioning pin sleeve 7 is internally integrated with a limiting structure, such as a limiting lug, a limiting groove and the like, so as to be used for fixing the wing locking positioning pin 6 inserted into the positioning pin sleeve. When the wing is in a locking position, the wing locking positioning pin 6 can be pushed by the wing locking connecting rod 4 to be inserted into the wing end multifunctional positioning pin sleeve 7 to be connected and fixed with the wing. Thus, the front end of the wing is inserted into the fuselage, and the bolt is only required to limit the up-and-down movement between the rear end of the wing and the fuselage. The bolt is not subjected to great force in the axial direction

Referring to fig. 2 and 3, in the unlocked state, the locking wrench is moved to the uppermost position. The locking wrench drives the tail locking connecting rod 3 or the wing locking connecting rod 4 upwards and rightwards, and the bolt is pulled out from the bolt sleeve to realize disassembly and unlocking.

Therefore, the locking and unlocking operation can be realized only by bare hands of a user without special equipment, and the locking and unlocking device is convenient to operate and high in efficiency.

Furthermore, the multifunctional positioning pin sleeves 7 and 8 are internally provided with an electrifying plug or an electric contact, and the electric contact is triggered to form an electric path or a signal path by inserting the tail locking positioning pin 5 into the tail end multifunctional positioning pin sleeve 8, or the electric contact is triggered to form an electric path or a signal path by inserting the wing locking positioning pin 6 into the wing end multifunctional positioning pin sleeve 7. Thus, the power-on or signal operation can be completed at the same time of locking. The power-on plugs or electrical contacts in the multifunctional locating pin bushings 7, 8 may be provided as several pins for plugging, similar to an aviation plug. It can also play the effect of round pin axle when circular telegram for joint strength is better, can bear bigger power.

The invention can also be provided with a cover plate on the surface of the body of the unmanned aerial vehicle. The apron can with locking spanner 2 seals in unmanned aerial vehicle's shell when locking spanner rocking arm 1 is in the latched position, and open when locking spanner rocking arm 1 is in the unblock position for locking spanner 2 stands out unmanned aerial vehicle's shell setting.

The device has intuitive and clear state reaction of the two modes, and can prevent misoperation. In particular, referring to fig. 3 or 5, when locking is forgotten, the upward locking wrench may obstruct the closing of the hatch door, and the power or signal of the drone may not be turned on. Thereby alerting the user to notice.

Thus, the present invention can be cumbersome by simplifying the installation process. The mechanism components of each component such as the tail and the wing can be locked simultaneously by only one action, so that the locking mechanism is simple, rapid and convenient, and the stress requirements of each component are met. Meanwhile, the multifunctional bolt can be internally provided with a plug for electrifying or signaling according to the requirement, and can be electrified or signaled when the locking action is finished. The two-mode reaction is visual and clear, and misoperation can be prevented.

The above are merely embodiments of the present invention, which are described in detail and with particularity, and therefore should not be construed as limiting the scope of the invention. It should be noted that, for those skilled in the art, various changes and modifications can be made without departing from the spirit of the present invention, and these changes and modifications are within the scope of the present invention.
