[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] like Figures 1 to 4 As shown, the present invention provides a sampling device for river water quality testing, including a sampling bucket 1: Pull plates 2 are provided on both the front and rear sides of the sampling barrel 1. A rotating rod 3 is provided on the outer side of the pull plate 2. The inner side of the rotating rod 3 passes through the pull plate 2 and the sampling barrel 1 and extends into the interior of the sampling barrel 1. The rotating rod 3 is fixedly connected to the pull plate 2 and movably connected to the inner wall of the sampling barrel 1. A sleeve 4 is fitted on the surface of the pull plate 2. A support block 5 is fixedly connected to the left side of the sleeve 4. A support rod 6 is fixedly connected to the left side of the support block 5. A transmission groove 7 is opened inside the sleeve 4. A push plate 8 is slidably connected inside the transmission groove 7. The end of the pull plate 2 away from the sampling barrel 1 extends into the interior of the transmission groove 7 and is fixedly connected to the outer side of the push plate 8. A slider 9 is fixedly connected to the left side of the pull plate 2. The left side of the slider 9 passes through to the left side of the support block 5 and is slidably connected to the support block 5.

[0018] refer to Figure 4A limiting plate 10 is fixedly connected to the left side of the slider 9. The right side of the limiting plate 10 is slidably connected to the left side of the support block 5. Two transmission boxes 11 are fixedly connected to the left side of the support block 5. A moving plate 12 is slidably connected to the top and bottom of the inner wall of the transmission box 11. The outer side of the moving plate 12 extends through to the outer side of the limiting plate 10 and is fixedly connected to a locking block 13. A pressing block 14 is fixedly connected to the end of the moving plate 12 near the transmission box 11. The end of the pressing block 14 away from the moving plate 12 extends through the transmission box 11 and is slidably connected to the transmission box 11.

[0019] As a technical optimization of this utility model, by setting a limiting plate 10, a transmission box 11, a moving plate 12, a locking block 13 and a pressing block 14, the slider 9 and the pull plate 2 can be limited, thus preventing the pull plate 2 from moving arbitrarily to both sides during use.

[0020] refer to Figure 4 The transmission groove 7 has two guide rods 15 fixedly connected laterally inside. The guide rods 15 pass through the push plate 8 and are slidably connected to the push plate 8.

[0021] As a technical optimization of this utility model, by setting the guide rod 15, the push plate 8 can be guided to prevent the push plate 8 from tilting and getting stuck when moving back and forth.

[0022] refer to Figure 4 Pressing pads 16 are provided at both the top and bottom of the transmission box 11. The end of the pressing pad 16 near the transmission box 11 is fixedly connected to the surface of the pressure block 14.

[0023] As a technical optimization of this utility model, by setting the pressing pad 16, it is convenient for the user to press the pressing block 14 inward, and prevents the user's fingers from feeling uncomfortable when pressing the pressing block 14 directly because the pressing block 14 is too hard.

[0024] refer to Figure 4 The transmission box 11 has two guide rods 17 fixedly connected vertically inside. The guide rods 17 pass through the moving plate 12 and are slidably connected to the moving plate 12.

[0025] As a technical optimization of this utility model, by setting the guide rod 17, the moving plate 12 can be moved in an auxiliary manner, thereby improving the stability of the moving plate 12 during movement.

[0026] refer to Figure 4 A spring rebounder 18 is fitted onto the surface of the guide rod 17, and the top and bottom of the spring rebounder 18 are fixedly connected to the surface of the movable plate 12.

[0027] As a technical optimization of this utility model, by setting the rebound device 18, the moving plate 12 can be moved outward automatically, thereby improving the performance of the moving plate 12.

[0028] The working principle and usage process of this utility model are as follows: When in use, first press the pressure block 14 inward with your finger. The pressure block 14 drives the moving plate 12, which slides on the surface of the guide rod 17, to move inward. The moving plate 12 drives the locking block 13 to move inward, so that the locking block 13 moves away from the limiting plate 10. After it moves away, the user pulls the pull plate 2 outward. The pull plate 2 drives the push plate 8 to move outward. At the same time, the pull plate 2 drives the push plate 8 to move outward, and the slider 9 moves outward. The slider 9 drives the limiting plate 10 to move outward, so that the limiting plate 10 moves away from the moving plate 12. After the pull plate 2 moves to the limit position, the rotating rod 3 moves away from the sampling bucket 1. After it moves away, the user replaces the sampling bucket 1 and reverses the above operation to install it.

[0029] In summary, this river water quality testing sampling device, by setting up a pull plate 2 and a rotating rod 3, can limit and rotate the sampling bucket 1, improving the practicality of the sampling bucket 1; by setting up a clamping sleeve 4, a transmission groove 7, a push plate 8, and a slider 9, the pull plate 2 can move back and forth, improving the performance of the pull plate 2; by setting up a limiting plate 10, a transmission box 11, a moving plate 12, and a locking block 13, the slider 9 can be fixed, and the pull plate 2 can move freely during the limiting process, thus providing the advantage of easy replacement of the sampling bucket 1. This solves the problem that most samplers connect the sampling bucket and the pull plate with bolts, which makes it impossible for the user to remove and replace the sampling bucket in a short time when it is damaged, and the bolts are prone to corrosion after repeated insertion into the river, causing the sampling bucket to be unable to rotate, reducing the practicality of the sampler.
