DETAILED DESCRIPTION

[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] like Figure 1 , 2 As shown in Figure 5, an embodiment of the utility model provides a drone that can be easily installed and disassembled, including a fuselage 1, wings 2 are inserted on both sides of the fuselage 1, a plurality of wing locking hooks 3 are fixed to the bottom surface of the wing 2, and the wing locking hooks 3 enable the fuselage 1 and the wing 2 to be detachably connected, a fixing groove 4 is provided on the bottom surface of the tail of the fuselage 1, a horizontal tail 5 is provided in the fixing groove 4, a pin shaft 6 is provided on the horizontal tail 5, a pin hole matching the pin shaft 6 is provided on the fuselage 1, and the top of the horizontal tail 5 is detachably connected to the fuselage 1 through the horizontal tail locking hook 8.

[0026] During the factory transportation, the fuselage 1, the wing 2 and the horizontal tail 5 are disconnected to achieve separate transportation, which reduces the space occupied during transportation, reduces the transportation cost, and reduces the risk of damage caused by transportation. When the user uses it, the wing 2 is plugged into the two sides of the fuselage 1, and then the lock hook is engaged, so that the assembly of the drone can be completed quickly without complicated tools or steps, which improves the assembly and use efficiency and enables the drone to be put into use more quickly. The axis of the pin 6 is in the same direction as the fuselage 1. When installing the horizontal tail 5, the pin 6 on the horizontal tail 5 is docked with the pin hole, and at the same time, the end of the horizontal tail 5 away from the pin 6 is lifted, so that the top surface of the horizontal tail 5 is against the fuselage 1. At this time, the pin 6 can be completely placed in the pin hole, and then the horizontal tail lock hook 8 is used to engage the horizontal tail 5, so that the rapid installation of the horizontal tail 5 can be achieved. By docking the pin 6 with the pin hole and engaging the horizontal tail lock hook 8, a rapid and stable installation is achieved.

[0027] like Figure 3 , 4As shown, the wing lock hook 3 and the horizontal tail lock hook 8 both include a cover plate 9, a fixing plate 10 is hinged at the bottom end of the cover plate 9, an L-shaped lock plate 11 is provided on the top of the fixing plate 10, a hanging plate 12 is hinged at the center of the cover plate 9, a cross bar 13 is fixed to the bottom of the hanging plate 12, the cover plate 9 is provided with a rotating groove 14 for the hanging plate 12 to rotate, a clamping rod 15 is hinged at the top of the cover plate 9 through a torsion spring, a hanging plate 16 is fixed to the side wall of the clamping rod 15, one end of the hanging plate 16 can be clamped with the lock plate 11 through a bending plate 17, and the other end passes through the gap between the cover plate 9 and the hanging plate 12, and a hook 18 connected to the cross bar 13 one by one is provided on the wing 2 and the horizontal tail 5.

[0028] When the horizontal tail 5 needs to be fixed, the fixing plate 10 is fixed on the fuselage 1, and the hanging plate 16 is pressed to disconnect the clamping connection with the locking plate 11, and the cover plate 9 is flipped downward. Under the action of the cover plate 9 flipping, the cover plate 9 drives the hanging plate 12 to move downward, and connects the cross bar 13 at the bottom of the hanging plate 12 with the hook 18, and then the cover plate 9 is flipped upward, and the cover plate 9 drives the hanging plate 12 to move upward, and tightens the horizontal tail 5 through the hook 18. When the hanging plate 16 is resisted by the hanging plate 12, the bending plate 17 will slide upward along the hanging plate 12 until the top of the hanging plate 16 is higher than the hanging plate 12. The bending plate 17 will be placed on the rear side of the hanging plate 12 under the action of the torsion spring, and the effect of self-locking clamping and fixing is achieved. When the wing 2 needs to be fixed, the fixing plate 10 can be fixed on the wing 2 or the fuselage 1, and connected with the hook 18 in the same way as the fixing of the horizontal tail 5. The cooperation of the bent plate 17 and the torsion spring in the lock hook mechanism realizes the self-locking function, ensuring the firm fixation of the horizontal tail 5 and the wing 2 during flight, and preventing the loosening of the components due to vibration or other external forces. When the horizontal tail 5 or the wing 2 needs to be inspected or replaced, the user can quickly unlock the lock hook mechanism and easily perform maintenance or replacement without the need for professional tools or too much time.

[0029] like Figure 7 , 8 As shown, a propeller 19 is fixed to the bottom of the wing 2 through a clamping plate, and the clamping plate includes an upper plate 20 and a lower plate 21. One side of the upper plate 20 is fixedly connected to the wing 2, and a plurality of fixing blocks 23 are fixed to both sides of the other side through pads 22. The end of the fixing block 23 away from the pad 22 forms a clamping groove 24 with the upper plate 20, and positioning grooves 25 for the fixing block 23 to pass through are provided on both sides of the lower plate 21. The lower plate 21 can move along the clamping groove 24, and a positioning plate 27 is fixed to the end of the lower plate 21 away from the clamping groove 24 through an elastic connecting plate 26. The positioning plate 27 is higher than the lower plate 21, and the end of the positioning plate 27 close to the lower plate 21 can be against the end face of the upper plate 20. A connecting rod is fixed to the bottom face of the lower plate 21 through a clamp, and the propeller 19 is fixed to both ends of the connecting rod.

[0030] When the propeller 19 needs to be installed, the positioning groove 25 of the lower plate 21 is passed through the fixing block 23 so that the side wall of the positioning groove 25 corresponds to the snap-in groove 24. At this time, the positioning plate 27 abuts against the upper plate 20, and the elastic connecting plate 26 is deformed, pushing the lower plate 21 so that the side wall at the positioning groove 25 is placed in the snap-in groove 24. When completely placed in the snap-in groove 24, the positioning plate 27 will completely extend out of the upper plate 20, and through the elastic recovery characteristics of the elastic connecting plate 26, the upper plate 20 and the lower plate 21 are quickly connected, achieving the effect of quickly installing the connecting rod and the bolt propeller. When leaving the factory, the connecting rod, the propeller 19 and the lower plate 21 can be directly assembled as a whole. The snap-in plate allows the user to quickly install or remove the propeller 19 without using complex tools or performing cumbersome steps. When leaving the factory, the connecting rod, the propeller 19 and the lower plate 21 are pre-assembled, which reduces the on-site assembly steps and speeds up the overall installation speed. The upper plate 20 and the lower plate 21 cooperate with each other through the fixing block 23 and the positioning groove 25 to form a stable clamping structure, thereby ensuring the stability of the propeller 19 during flight. The design of the elastic connecting plate 26 enables the lower plate 21 to easily pass through the fixing block 23 and be clamped into the clamping groove 24, while utilizing the elastic recovery characteristics to achieve a stable connection.

[0031] like Figure 5 , 6 As shown, the fuselage 1 is provided with a plurality of accommodating cavities 28 for accommodating the lock hooks or the horizontal tail lock hooks 8. By providing the accommodating cavities 28 to accommodate the wing lock hooks 3 or the horizontal tail lock hooks 8, when the UAV is flying, the number of parts protruding from the fuselage 1 can be reduced, thereby reducing air resistance and improving flight efficiency. At the same time, the accommodating cavities 28 provide protection for the lock hooks, preventing the lock hooks from being damaged due to collisions or other external factors during flight, extending the service life of the lock hooks, and the accommodating cavities 28 can also prevent the lock hooks from being damaged by impacts, wear, etc. during transportation, storage or use.

[0032] like Figure 5 As shown, a positioning pin 29 is fixed on the top of the horizontal tail 5, and the axis of the positioning pin 29 is in the same direction as the fuselage 1. The fuselage 1 is provided with a positioning groove 25 corresponding to the arc surface of the positioning pin 29. In order to prevent the horizontal tail 5 from deviation during installation, the positioning pin 29 and the positioning groove 25 are used as guides to enable the horizontal tail 5 to achieve accurate alignment during installation, thereby reducing installation deviations caused by human operation or mechanical errors and ensuring accurate connection between the horizontal tail 5 and the fuselage 1.

[0033] The fixing groove 4 is provided with a tail cover 30, one end of which is provided with a tail cover pin shaft 31, and the fuselage 1 is provided with a tail cover 30 pin hole that matches the tail cover pin shaft 31, and the tail cover 30 can be abutted against the bottom of the horizontal tail 5, and the tail cover 30 is fixed to the fuselage 1 through the tail lock hook. The tail cover 30 is fixed to the fuselage 1 through the tail lock hook and the tail cover 30 pin hole, so that the tail cover 30 will not fall off due to vibration or other reasons, ensuring that the horizontal tail 5 is in the correct position during flight. The tail cover 30 can cover the groove, reduce the turbulence and noise generated by the airflow in the groove, thereby improving the aerodynamic performance and flight stability of the drone. By fixing the tail cover 30, the connection strength between the horizontal tail 5 and the fuselage 1 can be further strengthened, and the stability of the overall structure can be improved.

[0034] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
