[0020] Please see Figure 1-4 This utility model provides a technical solution: a carbon fiber bracket connection device for a drone, including a bracket body 1, a connecting frame 2 fixedly connected to the upper surface of the bracket body 1, two connecting components 3 slidably connected to the inner bottom wall of the connecting frame 2, a rectangular groove is opened on the right side of the connecting frame 2, and a positioning component 4 is slidably connected to the inner wall of the rectangular groove.
[0021] The connecting component 3 is used to connect and assemble the bracket body 1 with the machine body, and the positioning component 4 is used to limit and prevent the connecting component 3 from detaching.
[0022] Furthermore, the connecting assembly 3 includes a strip frame 301, with transmission blocks 302 fixedly connected to the lower surfaces of both strip frames 301. Two sliding grooves are formed in the inner bottom wall of the connecting frame 2. A positive and negative threaded rod 303 is rotatably connected to the right side of the connecting frame 2. The left end of the positive and negative threaded rod 303 is rotatably connected to the left inner wall of the sliding groove. A circular ring 304 is fixedly connected to the right end of the positive and negative threaded rod 303. A positioning slot 305 is formed on the right side of the circular ring 304. The two transmission blocks 302 are threadedly connected to the positive and negative threads on the surface of the positive and negative threaded rod 303, respectively. A locking block 306 is fixedly connected to the opposite surfaces of both strip frames 301. A rectangular through hole is formed on the upper surface of the locking block 306. Two limiting grooves are formed in the inner wall of the rectangular through hole. The inner walls of the two limiting grooves are... A sliding connection is provided with a limiting block 307. A first spring 308 is fixedly connected to the inner wall of each of the two limiting grooves. The end of the first spring 308 away from the inner wall of the limiting groove is fixedly connected to the limiting block 307. A beveled top block 309 is fixedly connected to the side of the limiting block 307 away from the inner wall of the limiting groove, and both beveled top blocks 309 are slidably connected to the inner wall of the rectangular through hole. A movable cavity is provided inside the strip frame 301. A right-angle pressure plate 310 is slidably connected to the inner wall of the movable cavity. A threaded rod 311 is threadedly connected to the upper surface of the strip frame 301. The bottom end of the threaded rod 311 extends into the interior of the movable cavity and is rotatably connected to the upper surface of the right-angle pressure plate 310. A through hole is provided in the inner wall of the movable cavity. A snap-fit block 306 is located on the side of the strip frame 301 corresponding to the through hole. An ejector hole is provided at the position, and a movable groove is provided on the inner top wall of the ejector hole. A movable block 312 is slidably connected to the inner top wall of the movable groove. A second spring 313 is fixedly connected to the inner wall of the movable groove. The end of the second spring 313 away from the inner wall of the movable groove is fixedly connected to the movable block 312. A double-beveled push rod 314 is fixedly connected to the lower surface of the movable block 312. The two ends of the double-beveled push rod 314 correspond to the positions of the right-angle pressure plate 310 and the two beveled push blocks 309, respectively. After rotating the positive and negative threaded rods 303, the two strip frames 301 can be driven to move closer to each other through the two transmission blocks 302 until the two locking blocks 306 are inserted into the slots on both sides of the machine body. The inner top wall and inner bottom wall of the slots on both sides of the machine body are provided with locking grooves. At this time, rotating the two threaded rods 311 The threaded rod 311 drives the right-angle pressure plate 310 to descend within the movable cavity. The right-angle pressure plate 310 can press the double-sloped top rod 314, causing the two double-sloped top rods 314 to move closer to each other. During the movement of the two double-sloped top rods 314, they can press the second spring 313 through the moving block 312. At the same time, the two double-sloped top rods 314 can press the two sets of sloping top blocks 309, causing the sloping top blocks 309 to press the first spring 308 through the limiting block 307. This allows the two sets of sloping top blocks 309 to protrude through the upper and lower surfaces of the snap-fit block 306, thereby inserting into the locking groove. The snap-fit block 306 and the sloping top blocks 309 can achieve a double locking effect, thereby increasing the connection stability between the bracket body 1 and the machine body, preventing easy detachment.
[0023] Furthermore, the positioning component 4 includes a rectangular rod 401, a strip groove is formed on the inner top wall of the rectangular groove, a locking rod 402 is fixedly connected to the inner wall of the strip groove, a third spring 403 is sleeved on the surface of the locking rod 402, a rectangular block 404 is slidably connected to the inner top wall of the strip groove, the lower surface of the rectangular block 404 is fixedly connected to the upper surface of the rectangular rod 401, and the left end of the third spring 403 overlaps with the right side of the rectangular block 404, and the right end of the third spring 403 overlaps with the right inner wall of the strip groove. A right-angled locking block 405 is fixedly connected to the back of the rectangular rod 401, and the right-angled locking block 405 and the positioning slot 305 are connected. In accordance with the action of the third spring 403, the rectangular block 404 will drive the rectangular rod 401 to exert pressure to the left, and the right-angle locking block 405 will be tightly locked in the positioning slot 305 on the right side of the circular ring 304. This locks the angle of the circular ring 304 and the positive and negative threaded rod 303, ensuring that the positions of the two strip frames 301 will not shift. After the two locking blocks 306 are inserted into the machine body, the circular ring 304 will drive the positioning slot 305 to correspond exactly with the right-angle locking block 405. Therefore, there will be no problem that the right-angle locking block 405 cannot be locked into the positioning slot 305.
[0024] Working principle: First, the machine body is secured within the connecting frame 2. Pulling the right-angle locking block 405 forward disengages it from the positioning slot 305. At this point, the threaded rods 303 and the circular ring 304 are no longer restricted. Rotating the threaded rods 303 brings the two transmission blocks 302 closer together. The two transmission blocks 302 drive the two strip frames 301 closer together until the two locking blocks 306 are engaged in the slots on both sides of the machine body. Then, rotating the two threaded rods 311 lowers the right-angle pressure plate 310 within the movable cavity. The right-angle pressure plate 310 presses against the double-beveled push rods 314, causing them to move towards the center. During this movement, the moving block 312 presses against the second spring 313. The double-beveled push rods 314 press against the two beveled push blocks 309, thereby driving the two... The beveled top block 309 moves out from the upper and lower surfaces of the snap-fit block 306 and snaps into the locking groove in the slot. At this time, the right-angle snap-fit block 405 is released. The reaction force generated by the third spring 403 can drive the rectangular block 404 and the rectangular rod 401 to move to the left, thereby driving the right-angle snap-fit block 405 to re-insert into the positioning slot 305 on the right side of the circular ring 304. This locks the circular ring 304 and the positive and negative threaded rod 303. Through the double limiting effect of the snap-fit block 306 and the beveled top block 309, the connection stability between the bracket body 1 and the machine body can be ensured, and the bracket body 1 will not be dislodged due to shaking. In addition, the right-angle snap-fit block 405 plays a certain safety role, which can prevent the positive and negative threaded rod 303 from rotating. The locking effect is better and the efficiency is higher when disassembling.
