Drones are actually a general term for unmanned aerial vehicles. According to the flight platform configuration, drones can be divided into fixed-wing drones, rotary-wing drones, unmanned airships, parachute-wing drones, flapping-wing drones, etc.

[0003] Using fire extinguishing bombs to extinguish fire is a relatively convenient means of fire extinguishing. However, when the existing technology is used, the loading of fire extinguishing bombs is relatively complicated, which is very time-consuming and not conducive to rapid replacement. Therefore, we propose a rapid loading structure for fire extinguishing bombs for drones to solve the above problems. Utility Model Content

[0004] The purpose of the utility model is to solve the problem in the prior art that loading fire extinguishing bombs is complicated, time-consuming and not conducive to rapid replacement, and to propose a rapid loading structure for fire extinguishing bombs for drones.

[0005] In order to achieve the above-mentioned purpose, the present invention adopts the following technical solutions: a rapid loading structure of fire extinguishing bombs for UAV, comprising an overall structure and a fixed structure, wherein the fixed structure is located at the front and rear positions on both sides of the top of the overall structure;

[0006] The cam is provided with a plurality of sliding grooves at the front and rear positions on both sides of the top of the support plate, and a slide plate is slidably connected to the center of the inner wall of the slide plate. The front and rear positions of the inner wall of the slide plate are fixedly connected to a slide rod, and a compression spring is sleeved on the outer surface of the slide rod. The outer surfaces of the two sides of the slide plate are fixedly connected to a round rod near the front and rear positions of the bottom. The front and rear positions of the two sides of the bottom of the support plate are fixedly connected to the cylinder, and the inner wall of the cylinder is slidably connected to the connecting rod, and a tension spring is provided on the opposite side of the connecting rod and the cylinder. Electric push rods are fixedly installed at the front and rear positions on both sides of the top of the support plate, and the protruding end of the electric push rod is fixedly connected to the movable plate.

[0007] Preferably, the protruding end of the slide rod is fixedly connected to the outer surface of the skateboard, one end of the compression spring is fixedly connected to the outer surface of the skateboard, the other end of the compression spring is fixedly connected to the inner surface wall of the slide groove, and the outer surface of the movable plate is slidably connected to the outer surface of the skateboard.

[0008] Preferably, a circular hole is opened on the outer surface of the slide plate at the position of the round rod, and the inner surface wall of the circular hole is slidably connected to the outer surface of the round rod.

[0009] Preferably, a circular ring is slidably connected to the outer surface of the round rod, and the fire extinguishing bomb body is fixedly connected to the bottom center of the circular ring.

[0010] Preferably, the outer surface of the connecting rod is fixedly connected to the outer surface of the slide plate, one end of the tension spring is fixedly connected to the inner wall of the cylinder, and the other end of the tension spring is fixedly connected to the outer surface of the connecting rod.

[0013] Compared with the prior art, the advantages and positive effects of the present invention are:

[0014] 1. In the utility model, when in use, the user can pass the circular ring through the two round rods, and then the user can manually slide the two slide plates toward the center in the slide groove. At this time, the slide rod and the compression spring are stressed, and the two round rods are driven together by the force. Finally, the two round rods will enter the two round holes, and then the electric push rod will extend to drive the movable plate to move forward and backward, so that the movable plate can contact the outer surface of the slide plate. The contact can restrict it to prevent it from sliding in the slide groove, and also indirectly restrain the compression spring, thereby completing the installation of the fire extinguishing bomb body. The installation process is relatively simple, so that it will not take too much time for each subsequent loading.

[0015] 2. In the utility model, when the movable plate is no longer in contact with the slide plate, its compression spring loses its restraining force and drives the slide plate to slide in the slide groove. At this time, the round rod is stressed and can be separated from the round hole. Through the cooperation of the tension spring, the connecting rod and the cylinder, the slide plate can be powerfully moved to both sides, so that the round rod can be separated from the ring, and then the fire extinguishing bomb can fall freely to the fire point. Through the mutual cooperation of the connecting plate, the threaded hole and the fixing bolt, it is convenient for the user to fix the whole at the bottom position of the drone.

However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0023] Example 1, as Figures 1-4 As shown, a rapid loading structure for fire extinguishing bombs for drones includes an overall structure 1 and a fixed structure 2, the fixed structure 2 is located at the front and rear positions on both sides of the top of the overall structure 1; the overall structure 1 includes a support plate 101, and a slide groove 108 is opened at the front and rear positions on both sides of the top of the support plate 101, and a slide plate 105 is slidably connected to the center of the inner wall of the slide groove 108, and a slide rod 106 is fixedly connected to the front and rear positions on both sides of the inner wall of the slide groove 108, and a compression spring 107 is sleeved on the outer surface of the slide rod 106, and a round rod 109 is fixedly connected to the outer surface of the two sides of the slide plate 105 near the front and rear positions of the bottom, and a cylinder 113 is fixedly connected to the front and rear positions on both sides of the bottom of the support plate 101, and a connecting rod 112 is slidably connected to the inner wall of the cylinder 113, and a tension spring 114 is provided on the opposite side of the connecting rod 112 and the cylinder 113, and an electric push rod 103 is fixedly installed at the front and rear positions on both sides of the top of the support plate 101, and the protruding end of the electric push rod 103 is fixedly connected to the movable plate 104.

[0024] The effect achieved by the entire embodiment 1 is as follows: Figure 3As shown, in the subsequent actual use, the circular holes 111 are arranged at the front and rear positions of the slide plate 105, then the round rod 109 located on one side near the front side will enter the circular hole 111 located on the other side near the front side, and the round rod 109 located on the other side near the rear side will enter the circular hole 111 located on one side near the rear side, and they are staggered so that they can be used later, and at the same time, it can also ensure that the ring 110 can be stably located on the two round rods 109.

[0025] Example 2, as Figures 1-4 As shown, the extended end of the slide rod 106 is fixedly connected to the outer surface of the slide plate 105, one end of the compression spring 107 is fixedly connected to the outer surface of the slide plate 105, and the other end of the compression spring 107 is fixedly connected to the inner surface wall of the slide groove 108. The outer surface of the movable plate 104 is slidably connected to the outer surface of the slide plate 105. The outer surface of the slide plate 105 is provided with a circular hole 111 at the position of the round rod 109. The inner surface wall of the circular hole 111 is slidably connected to the outer surface of the round rod 109. The outer surface of the round rod 109 is slidably connected with a ring 110. The bottom center of the ring 110 is fixedly connected to the fire extinguishing bomb body 102. The outer surface of the rod 112 is fixedly connected to the outer surface of the skateboard 105, one end of the tension spring 114 is fixedly connected to the inner wall of the cylinder 113, and the other end of the tension spring 114 is fixedly connected to the outer surface of the connecting rod 112. The fixing structure 2 includes a connecting plate 201, and a fixing bolt 203 is threaded through the bottom center of the connecting plate 201. The bottom surface of the connecting plate 201 is fixedly connected to the top surface of the support plate 101. A threaded hole 202 is provided at the bottom of the connecting plate 201 at the position of the fixing bolt 203, and the inner wall of the threaded hole 202 is threadedly connected to the outer surface of the fixing bolt 203.

[0026] The effect achieved by the entire embodiment 2 is that when the slide plate 105 slides left and right in the slide groove 108, it will also drive the connecting rod 112 to slide in the cylinder 113, and its tension spring 114 will be forced to change its own state. Then, when the slide plate 105 is no longer restrained, the connecting rod 112 can use the tension of the tension spring 114 to rotate the slide plate 105 to both sides, thereby ensuring that the round rod 109 can normally detach from the ring 110, so that the ring 110 and the fire extinguishing bomb body 102 can fall normally. Through the mutual cooperation of the connecting plate 201, the threaded hole 202 and the fixing bolt 203, it is convenient for the user to disassemble and assemble the whole.

[0027] Working principle: the user first puts the fire extinguisher body 102 and the ring 110 under the support plate 101, and puts the ring 110 on the two round rods 109, and then manually moves the two slides 105 so that they can move toward the center in the slide groove 108. At this time, the slide rod 106 and the compression spring 107 are forced to change their state, and the connecting rod 112 is forced to slide in the cylinder 113, and the tension spring 114 is also forced to change its own state. Then, after moving to a certain position, the two round rods 109 enter the round holes 111 on both sides respectively, and then the electric push rod 103 is extended to drive the movable plate 104 to move forward and backward, so that the movable plate 104 can move to contact with the outer surface of the slide plate 105. The contact can restrict it to prevent it from sliding in the slide groove 108 later. From then on, the installation of the fire extinguisher body 102 is completed, and its installation process is relatively simple. The two round rods 109 are driven by the force and can be separated from the two round holes 111. When the two round rods 109 move to a certain position on both sides, they can be separated from the ring 110. Then the ring 110 and the fire extinguisher body 102 can fall freely to the fire point to extinguish the fire.
