[0004] The inventors discovered in their daily work that the existing method of fixing the connector to the connecting pipe by connecting a limiting ring to the connecting pipe threadedly is cumbersome. This requires repeated rotation of the limiting ring to secure the connector, resulting in low installation efficiency.

[0031] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0032] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0033] Please see Figure 1 and Figure 2 This utility model provides a rapid detection device for plant soil nutrients, comprising: a detection device 1, a plurality of buttons 7 and a connecting pipe 8 installed on the inner wall of the detection device 1, a connector 5 slidably electrically connected to the inner wall of the connecting pipe 8, a transmission line 2 fixedly electrically connected to the end of the connector 5 away from the detection device 1, a detection head 6 fixedly electrically connected to the end of the transmission line 2 away from the connector 5, an installation structure 3 provided on the arc surface of the connector 5, and a limiting structure 4 provided on one side of the detection device 1.

[0034] In the embodiments of this utility model, please refer to Figure 3 and Figure 4The installation structure 3 includes a fixing ring 312 and a fixing plate 308. The fixing ring 312 is fixedly connected to the connector 5, and the fixing plate 308 is fixedly connected to the connecting pipe 8. Two connecting plates 309 and two fixing brackets 301 are fixedly connected to the arc surface of the fixing ring 312. A positioning rod 310 is fixedly connected to the side of the connecting plate 309 near the fixing plate 308. Two limiting grooves 302 are opened on the inner wall of the fixing bracket 301. Moving blocks 303 are slidably connected to the inner wall of the limiting grooves 302. The two moving blocks 303... A movable plate 306 is fixedly connected to one side of the movable block 303, which is away from the fixed ring 312. A spring 305 is provided between the movable block 303 and the limiting groove 302. The two ends of the spring 305 are fixedly connected to the movable block 303 and the limiting groove 302, respectively. A locking block 307 is fixedly connected to the side of the movable plate 306 near the fixed ring 312. Two positioning holes 313 are opened on the inner wall of the fixed plate 308. The positioning holes 313 are slidably connected to the positioning rod 310. The movable plate 306 is slidably connected to the fixed frame 301. This design allows the locking block 307 and the positioning rod 310 to facilitate the installation of the connector 5 on the connecting pipe 8 when the personnel need to limit the connector 5, thereby speeding up the installation and improving the work efficiency. A limiting rod 304 is fixedly connected to the inner wall of the limiting groove 302, and the limiting rod 304 is slidably connected to the movable block 303. The limiting rod 304 can limit the movement block 303, preventing it from shifting during sliding on the inner wall of the limiting groove 302. The locking block 307 is made of stainless steel and is a right-angled triangle. The stainless steel block has high strength and good wear resistance, preventing deformation of the locking block 307 during short-term use. A guide block 311 is fixedly connected to the end of the positioning rod 310 away from the connecting plate 309. The guide block 311 guides the positioning rod 310, facilitating its sliding into the inner wall of the positioning hole 313.

[0035] In the embodiments of this utility model, please refer to Figure 5 and Figure 6The limiting structure 4 includes two connecting frames 41, which are fixedly connected to the detection device 1. A rotating rod 42 is rotatably connected to the inner wall of each connecting frame 41. An elastic band 43 is fixedly connected to the arc surface of the rotating rod 42. A limiting band 44 is fixedly connected to one end of each elastic band 43 that is close to the other. This design allows the operator's hand to be restrained by the two elastic bands 43 and the limiting band 44 when the operator holds the detection device 1 to test the nutrients in the plant soil. This prevents the detection device 1 from accidentally slipping from the operator's hand during prolonged operation. An anti-slip pad 45 is fixedly connected to the side of the limiting band 44 closest to the detection device 1. The anti-slip pad 45 increases the friction between the operator's hand and the limiting band 44, preventing slippage. A pull ring 46 with a circular cross-section is fixedly connected to the side of the limiting band 44 furthest from the detection device 1. The pull ring 46 allows for easy movement of the limiting band 44, improving the operator's ease of use.

[0036] The working principle of the rapid plant soil nutrient detection device provided by this utility model is as follows:

[0037] When personnel need to insert connector 5 into the inner wall of connecting pipe 8 to use detection head 6 to test plant soil, they can first move connector 5. Connector 5 drives fixing ring 312 to move closer to connecting pipe 8. Fixing ring 312 drives two connecting plates 309 and two fixing brackets 301 to move closer to connecting pipe 8. Connecting plate 309 drives positioning rod 310 to move closer to connecting pipe 8. Positioning rod 310 drives guide block 311 to move closer to connecting pipe 8. Fixing bracket 301 drives two limit rods 304, two moving blocks 303, and two... Spring 305 moves towards the connecting pipe 8, and two moving blocks 303 drive moving plate 306 towards the connecting pipe 8. Moving plate 306 drives locking block 307 towards the connecting pipe 8 until the connector 5 slides into the inner wall of the connecting pipe 8. During the process of connector 5 sliding into the inner wall of the connecting pipe 8, guide block 311 and positioning rod 310 slide into the inner wall of positioning hole 313. Guide block 311 can guide positioning rod 310, making it easy for personnel to slide positioning rod 310 into the inner wall of positioning hole 313. Then positioning rod 310 is in the inner wall of positioning groove. During the sliding process, the two locking blocks 307 abut against the fixed plate 308, causing the locking blocks 307 to move away from the fixed ring 312. The locking blocks 307 then drive the moving plate 306 to move away from the fixed plate 308, which in turn drives the two moving blocks 303 to move away from the fixed plate 308. The moving blocks 303 slide on the arc surface of the limiting rod 304, which limits the movement of the moving blocks 303, preventing misalignment during sliding on the inner wall of the limiting groove 302. The moving blocks 303 also drive... Spring 305 is wound up until the fixing ring 312 abuts against the fixing plate 308. At this time, spring 305 rebounds, causing the locking block 307 to move closer to the connecting pipe 8 until the locking block 307 moves to the lower surface of the fixing plate 308. The locking block 307 is a stainless steel block, which has high strength and good wear resistance, and can prevent the locking block 307 from deforming during short-term use. Then, the operator inserts the detection head 6 into the soil to be tested and operates the detection device 1 through the button 7. Finally, the operator can view the test data on the display screen of the detection device 1.

[0038] Additionally, when personnel need to use the handheld testing device 1 to test the plant soil, they can first use the pull ring 46 to move the limiting band 44 away from the testing device 1. The pull ring 46 facilitates the movement of the limiting band 44, improving the ease of operation. Then, the limiting band 44 stretches the two elastic bands 43, which also moves the anti-slip pad 45 away from the testing device 1. The anti-slip pad 45 increases the friction between the personnel's hand and the limiting band 44, preventing slippage. The elastic bands 43 also rotate the rotating rod 42. When the limiting band 44 moves to the appropriate position, the personnel pass their handle between the limiting band 44 and the testing device 1, and then release the pull ring 46. At this time, the two elastic bands 43 rebound, causing the anti-slip pad 45 to fit against the back of the personnel's hand.

[0039] The circuits and controls involved in this utility model are all existing technologies and will not be described in detail here.

[0040] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the description and drawings of this utility model, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
