Description

Technical Field

[0001] This utility model relates to the field of connector technology, and in particular to a quick-connect connector for pesticide pipelines of plant protection drones. Background Technology

[0002] Agricultural drones are unmanned aerial vehicles used for the protection of agricultural and forestry plants. They can spray pesticides, fertilizers or sow seeds accurately and efficiently through ground remote control or autonomous navigation. The pesticide pipeline docking connector of agricultural drones is a key component located between the drone and the pesticide tank, spray boom or intelligent irrigation station. It is mainly used to achieve a fast and reliable connection and sealing of the pesticide delivery pipeline.

[0003] Most existing pesticide pipeline connectors are not convenient for replacing gaskets. When gasket replacement is needed, special tools are required, which affects the efficiency of gasket replacement. In addition, most existing pesticide pipeline connectors connect pipelines by tightening threads, and the threads will wear and strip after long-term use, making it impossible to effectively connect the pipelines together.

[0004] Therefore, those skilled in the art have provided a quick-connect connector for pesticide pipelines of agricultural drones to solve the problems mentioned in the background art. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a quick-connect connector for pesticide pipelines on agricultural drones. This pipeline connector uses a limiting and fixing block and a limiting groove, followed by the cooperation of a second magnet and a first magnet, and then a rigid locking block and a locking groove to quickly fix the first and second pairs of connecting pipes. Through the designed splicing mechanism, the pipelines can be quickly connected, thereby effectively improving connection efficiency.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] A quick-connect connector for pesticide pipelines of a plant protection drone includes a first pesticide tube and a second pesticide tube. The lower end of the first pesticide tube is provided with a splicing mechanism. The splicing mechanism includes a first pair of connecting pipes fixedly connected to the lower end of the first pesticide tube. The body of the first pair of connecting pipes has multiple snap-fit ​​grooves. Push blocks are slidably connected inside each snap-fit ​​groove. Limiting blocks are fixedly connected to the front and rear ends of the inner walls of the first pair of connecting pipes. A second magnet is fixedly connected to the inner top surface of the first pair of connecting pipes. The splicing mechanism also includes a second pair of connecting pipes fixedly connected to the upper end of the second pesticide tube. The front and rear ends of the body of the second pair of connecting pipes have limit grooves. The lower end of the body of the second pair of connecting pipes has multiple receiving grooves. Rigid blocks are rigidly connected to the inner bottom surfaces of each receiving groove. A first magnet is fixedly connected to the inner bottom surface of the second pair of connecting pipes.

[0008] The splicing mechanism is equipped with a replacement mechanism. The replacement mechanism includes a first sealing tube fixedly connected to the middle of the bottom surface of the second pair of pipes. A second fixing groove is opened on the upper surface of the first sealing tube. A sealing gasket is snapped and fixed inside the second fixing groove. A fixing ring is fixedly connected to the outer wall of the sealing gasket. A replacement ring is fixedly connected to the inner wall of the sealing gasket. A first fixing groove is opened on the inner wall of the second fixing groove.

[0009] Through the above technical solution, the pipe connector uses the cooperation of the limiting fixing block and the limiting groove, followed by the cooperation of the second magnet and the first magnet, and then the rigid locking block and the locking groove to quickly fix the first pair of pipes and the second pair of pipes. Through the set splicing mechanism, the pipes can be quickly connected, thereby effectively improving the connection efficiency.

[0010] Furthermore, a second sealing tube is fixedly connected to the middle of the bottom surface of the first connecting tube, the lower surface of the second sealing tube is tightly fitted with the replacement ring, and the fixing ring is engaged with the first fixing groove.

[0011] The above technical solution involves setting a second sealing tube, which can work with a sealing gasket to seal the first and second pairs of connecting pipes. The sealing gasket can be fixed by engaging the fixing ring with the first fixing groove.

[0012] Furthermore, the sealing gasket is made of fluororubber;

[0013] The above technical solution, by using fluororubber as the sealing gasket, ensures the reliability of the seal.

[0014] Furthermore, the upper end of the rigid block engages with the locking groove;

[0015] The above technical solution allows for the snap-fit ​​fixing of the first and second connecting pipes.

[0016] Furthermore, limiting grooves are provided on both sides of the top and bottom surfaces of the snap-fit ​​groove, and limiting blocks are fixedly connected to both sides of the upper and lower ends of the push block, and the limiting blocks slide inside the limiting grooves.

[0017] The above technical solution uses a limiting block and a limiting slide to limit the movement of the push block, thereby preventing the push block from sliding out of the first pair of connecting pipes.

[0018] Furthermore, the first pair of connecting pipes and the second pair of connecting pipes are fixed together by rigid locking blocks;

[0019] The above technical solution facilitates the disassembly of the first pair of pipes and the second pair of pipes.

[0020] Furthermore, the block body of the limiting and fixing block slides inside the limiting groove;

[0021] The above technical solution enables the first pair of connectors and the second pair of connectors to slide in a limited manner.

[0022] Furthermore, the first magnet and the second magnet attract each other;

[0023] The above technical solution facilitates the splicing of the first and second pairs of connectors.

[0024] This utility model has the following beneficial effects:

[0025] 1. The present invention proposes a quick-connect connector for pesticide pipelines of plant protection drones. Compared with most existing pesticide pipeline connectors, this pipeline connector uses the cooperation of a limiting fixing block and a limiting groove, followed by the cooperation of a second magnet and a first magnet, and then the engagement of a rigid locking block with a locking groove to quickly fix the first pair of connecting pipes and the second pair of connecting pipes. Through the designed splicing mechanism, the pipelines can be quickly connected, thereby effectively improving the connection efficiency.

[0026] 2. The quick-connect connector for pesticide pipelines of plant protection drones proposed in this utility model, compared with most existing pesticide pipeline connectors, uses a fixed ring to fix the sealing gasket into the second fixed groove through the cooperation of the fixed ring and the first fixed groove. The sealing gasket can be replaced by the set replacement ring. The set replacement mechanism allows the sealing gasket to be replaced without the need for other tools. Attached Figure Description

Detailed Implementation

[0034] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of specific embodiments. Obviously, the described specific embodiments are only a part of the specific embodiments of the present invention, and not all of them. Based on the specific embodiments of the present invention, all other specific embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0035] One specific embodiment of this utility model is provided:

[0036] Reference Figure 1 , Figure 2 and Figure 3A quick-connect connector for pesticide pipelines of a plant protection drone includes a first pesticide tube 1 and a second pesticide tube 3. The lower end of the first pesticide tube 1 is provided with a splicing mechanism 2. The splicing mechanism 2 includes a first pair of connecting pipes 201 fixedly connected to the lower end of the first pesticide tube 1. The tube body of the first pair of connecting pipes 201 has multiple snap-fit ​​grooves 208. Push blocks 202 are slidably connected inside the snap-fit ​​grooves 208. Limiting blocks 209 are fixedly connected to the front and rear ends of the inner wall of the first pair of connecting pipes 201. A second magnet 207 is fixedly connected to the inner top surface of the first pair of connecting pipes 201. The splicing mechanism 2 also includes a second pair of connecting pipes 205 fixedly connected to the upper end of the second pesticide tube 3. Limiting grooves 204 are provided at the front and rear ends of the tube body of the second pair of connecting pipes 205. Multiple receiving grooves 210 are provided at the lower end of the tube body of the second pair of connecting pipes 205. Rigid blocks 206 are rigidly connected to the inner bottom surface of the receiving grooves 210. A first magnet 203 is fixedly connected to the inner bottom surface of the second pair of connecting pipes 205.

[0037] Reference Figure 4 The splicing mechanism 2 is equipped with a replacement mechanism 4. The replacement mechanism 4 includes a first sealing tube 406 fixedly connected to the middle of the bottom surface of the second coupling tube 205. A second fixing groove 402 is opened on the upper surface of the first sealing tube 406. A sealing gasket 403 is snapped and fixed inside the second fixing groove 402. A fixing ring 405 is fixedly connected to the outer wall of the sealing gasket 403. A replacement ring 404 is fixedly connected to the inner wall of the sealing gasket 403. A first fixing groove 401 is opened on the inner wall of the second fixing groove 402.

[0038] The pipe connector uses the cooperation of the limiting fixing block 209 and the limiting groove 204, followed by the cooperation of the second magnet 207 and the first magnet 203, and then the rigid locking block 206 and the locking groove 208 to quickly fix the first pair of pipes 201 and the second pair of pipes 205. Through the splicing mechanism 2, the pipes can be quickly connected, thereby effectively improving the connection efficiency.

[0039] Reference Figure 5 and Figure 6 A second sealing tube 407 is fixedly connected to the middle of the inner bottom surface of the first pair of connecting tubes 201. The lower surface of the second sealing tube 407 is tightly fitted with the replacement ring 404. The fixing ring 405 is engaged with the first fixing groove 401. By setting the second sealing tube 407, the first pair of connecting tubes 201 and the second pair of connecting tubes 205 can be sealed together with the sealing gasket 403. By engaging the fixing ring 405 with the first fixing groove 401, the sealing gasket 403 can be fixed. The sealing gasket 403 is made of fluororubber. By using fluororubber as the sealing gasket 403, the reliability of the seal can be guaranteed.

[0040] Reference Figure 5 and Figure 6The upper end of the rigid locking block 206 engages with the locking groove 208, thereby securing the first pair of connecting pipes 201 and the second pair of connecting pipes 205. Limiting grooves 212 are provided on both sides of the inner top and bottom surfaces of the locking groove 208. Limiting blocks 211 are fixedly connected to both sides of the upper and lower ends of the push block 202. The limiting blocks 211 slide within the limiting grooves 212. Through the limiting blocks 211 and the limiting grooves 212, the push block 202 is limited in its movement, thus preventing the push block 202 from moving. 02 The first pair of connecting pipes 201 slides out. The first pair of connecting pipes 201 and the second pair of connecting pipes 205 are fixed by a rigid locking block 206, which facilitates the disassembly of the first pair of connecting pipes 201 and the second pair of connecting pipes 205. The body of the limiting fixing block 209 slides inside the limiting groove 204, which allows the first pair of connecting pipes 201 and the second pair of connecting pipes 205 to slide in a limited manner. The first magnet 203 and the second magnet 207 attract each other, which facilitates the splicing of the first pair of connecting pipes 201 and the second pair of connecting pipes 205.

[0041] Working principle: When connecting the pipeline, firstly, the limiting and fixing block 209 needs to be aligned with the limiting groove 204. Then, the second magnet 207 and the first magnet 203 attract each other, thus connecting together. Then, the rigid locking block 206 is squeezed by the first pair of connecting pipes 201, causing the upper end of the rigid locking block 206 to be pressed back into the receiving groove 210. Then, when the upper end of the rigid locking block 206 moves to the snap-fit ​​groove 208, the rigid locking block 206 releases pressure and enters the snap-fit ​​groove 208. Then, the rigid locking block 206 snaps into the snap-fit ​​groove 208, thus splicing and fixing the first pair of connecting pipes 201 and the second pair of connecting pipes 205 together. At the same time, the second sealing pipe 407 will fit tightly with the sealing gasket 403 to achieve a sealing effect. When disassembly is required, the push block 202 is pressed down simultaneously. Then, push block 202 pushes out the rigid locking block 206 that is locked inside the locking groove 208, and then pulls the second connecting pipe 205 outward to separate the first magnet 203 from the second magnet 207. When the sealing gasket 403 needs to be replaced, the replacement ring 404 is dragged outward to disengage the fixing ring 405 from the first fixing groove 401, thereby disassembling the sealing gasket 403. When replacing the new sealing gasket 403, the sealing gasket 403 is aligned with the second fixing groove 402 and then pressed down to lock the fixing ring 405 into the first fixing groove 401, thereby fixing the sealing gasket 403. The push block 202 is limited by the sliding of the limiting block 211 inside the limiting slide groove 212, thereby preventing the push block 202 from sliding out.
