[0019] In order to better understand the above technical solutions, the above technical solutions will be described in detail below in conjunction with the accompanying drawings of the specification and specific embodiments.

[0020] An embodiment of the present application discloses a connection structure between a flame retardant sprayer and a drone. Refer to Figure 1 , Figure 2 and Figure 3 , which includes a mounting plate 3 provided at the bottom of the flame retardant sprayer 2. In the embodiment of the present application, the drone includes a drone main body and two support frames 1. The two support frames 1 are spaced apart and provided at the bottom of the drone main body. The support frame 1 includes two vertical rods 12 and a cross bar 11 connected between the two vertical rods 12. Two elastic blocks 4 are slidably provided on the mounting plate 3 along a direction perpendicular to the length of the cross bar 11. A card slot 41 for clamping and cooperating with the cross bar 11 is provided on the surface of the elastic block 4 away from the mounting plate 3. A first limiting member 5 for restricting the movement of the elastic block 4 is mounted on the mounting plate 3.

[0021] In the embodiment of the present application, the elastic block 4 is an elastic plastic block. The mounting plate 3 is provided at the bottom of the flame retardant sprayer 2. When the staff installs the mounting plate 3 on the support frame 1, the two elastic blocks 4 can be moved, and the two elastic blocks 4 are clamped and cooperated with the cross bar 11 on the corresponding support frame 1. Subsequently, the first limiting member 5 can be used to restrict the movement of the elastic block 4 relative to the mounting plate 3. Through this connection structure, the flame retardant sprayer 2 can be firmly installed on the drone, which has the effect of improving the installation stability of the flame retardant sprayer 2 on the drone.

[0022] Specifically, the first limiting member 5 includes a first limiting bolt. A sliding groove 31 for the elastic block 4 to move is provided on the mounting plate 3. A strip-shaped hole 32 for the first limiting bolt to pass through is provided on the inner bottom wall of the sliding groove 31 along its own length direction. A first threaded hole is provided on the elastic block 4 at the strip-shaped hole 32. After the first limiting bolt passes through the strip-shaped hole 32, it is threadedly connected to the first threaded hole.

[0023] Further, a mounting rod 6 is movably provided on the mounting plate 3 along a direction perpendicular to the length of the sliding groove 31. A lock catch 7 for connecting the vertical rod 12 is mounted at one end of the mounting rod 6 away from the mounting plate 3. The lock catch 7 includes a baffle 71 provided at the end of the mounting rod 6 and a pressing plate 72 rotatably provided on one side of the baffle 71. A groove for pressing and contacting the vertical rod 12 is provided on the pressing plate 72. A second limiting member 8 for restricting the rotation of the pressing plate 72 relative to the rotating plate is mounted at the movable end of the pressing plate 72.

[0024] In the embodiment of the present application, moving the mounting rod 6 can make the baffle 71 contact the side wall of the vertical rod 12. Subsequently, rotating the pressing plate 72 can make the pressing plate 72 and the baffle 71 jointly clamp the vertical rod 12. The second limiting member 8 can be used to restrict the rotation of the pressing plate 72 relative to the baffle 71. In this way, the installation stability of the mounting plate 3 on the support frame 1 can be further improved.

[0025] Specifically, a second threaded hole is formed in the mounting plate 3 along the direction perpendicular to the length of the sliding groove 31. The mounting rod 6 is threadedly connected in the second threaded hole, and the baffle 71 is coaxially rotatably arranged at one end of the mounting rod 6 away from the mounting plate 3.

[0026] In the embodiment of the present application, rotating the mounting rod 6 can make it move and contact the vertical rod 12, and then rotating the baffle 71 so that the pressing plate 72 can cooperate with the baffle 71 to jointly clamp the vertical rod 12.

[0027] Refer to Figure 4 , the second limiting member 8 includes a second limiting bolt. A through hole for the second limiting bolt to pass through is formed in the movable end of the pressing plate 72, and a third threaded hole is formed in the baffle 71. After the second limiting bolt passes through the through hole, it is threadedly connected in the third threaded hole.

[0028] Furthermore, a plurality of damping spring shock absorbers 9 are connected between the mounting plate 3 and the flame retardant sprayer 2.

[0029] In the embodiment of the present application, the two ends of the damping spring shock absorber 9 are respectively bolted to the mounting plate 3 and the flame retardant sprayer 2. When the drone lands on the ground, the damping spring shock absorber 9 can play a role in damping the flame retardant sprayer 2.

[0030] The implementation principle of the connection structure between the flame retardant sprayer and the drone in the embodiment of the present application is as follows: The mounting plate 3 is arranged at the bottom of the flame retardant sprayer 2. When the staff installs the mounting plate 3 on the support frame 1, the two elastic blocks 4 can be moved, and the two elastic blocks 4 are clamped and matched with the cross bars 11 on the corresponding support frame 1. Subsequently, the first limiting member 5 can be used to limit the movement of the elastic blocks 4 relative to the mounting plate 3. Through this connection structure, the flame retardant sprayer 2 can be firmly installed on the drone, having the effect of improving the installation stability of the flame retardant sprayer 2 on the drone.
