Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the protection scope of the present utility model.

[0023] The following gives specific embodiments.

[0024] Such as Figures 1 to 2As shown, a chemical detection sampling device described in an embodiment of the utility model comprises a sampling cylinder 1; a discharge port is provided on the side wall of the sampling cylinder 1; an inner rotating sleeve 2 is rotatably connected inside the sampling cylinder 1; a plurality of storage cavities are provided inside the inner rotating sleeve 2, and a discharge port connected to the storage cavity is provided on the side wall of the inner rotating sleeve 2; the discharge port on the side wall of the sampling cylinder 1 is arranged correspondingly to the discharge port on the side wall of the inner rotating sleeve 2; a handwheel turntable 3 is fixedly connected to the top of the inner rotating sleeve 2; a plurality of anti-skid protrusions 4 are fixedly connected to the side wall of the sampling cylinder 1, and the anti-skid protrusions 4 are regularly arranged in a circular array on the side wall of the sampling cylinder 1; during operation, when it is necessary to sample a chemical solution, a sampling port that is consistent with the liquid level of the solution is selected Cylinder 1, and insert the sampling cylinder 1 into the solution in a manner perpendicular to the liquid surface. After the sampling cylinder 1 is completely inserted into the solution, you can hold the anti-slip protrusion 4 and turn the handwheel dial 3 to connect the sampling cylinder 1 with the discharge port on the side wall of the inner rotating sleeve 2, so that solutions at various places enter different storage cavities, so that samples can be taken from various places inside the solution at the same time. After the sampling is completed, the handwheel dial 3 can be turned to stagger the discharge port of the inner rotating sleeve 2 and the sampling cylinder 1, and the inner rotating sleeve 2 can be closed. After taking the sampling cylinder 1 out of the solution, the sampling of the solution can be completed. After that, the solution inside the inner rotating sleeve 2 can be poured out and mixed, which can make the sampled solution more uniform and effectively avoid precipitation of the solution, which may affect the detection.

[0025] like Figures 1 to 3 As shown, an external ball 5 is fixedly connected to the side wall of the sampling cylinder 1; a snap-fitting ring 6 is snap-fitted to the outside of the external ball 5; a holding handle 7 is fixedly connected to the side wall of the snap-fitting ring 6; a counterweight plate 10 is provided at the bottom of the sampling cylinder 1; a threaded rod 101 is fixedly connected to the top of the counterweight plate 10; the threaded rod 101 is threadedly connected to the internal position of the sampling cylinder 1; during operation, when it is necessary to sample the solution, the holding handle 7 can be held, and the snap-fitting ring 6 can be used to fit the external ball 5, so that the sampling cylinder 1 can be deflected without falling off, and the sampling cylinder 1 will gradually sag under the influence of gravity, so that the sampling cylinder 1 can remain vertical inside the solution, making the sampling of the solution more accurate, and under the influence of gravity on the counterweight plate 10, the sampling cylinder 1 can be made vertical faster.

[0026] like Figure 1 and Figure 5As shown, a liquid guide plate 8 is provided on the side wall of the sampling cylinder body 1; a fixed sleeve 9 is fixedly connected to the top of the liquid guide plate 8; the fixed sleeve 9 is snap-connected to the anti-slip convex block 4; during operation, when it is necessary to take out the solution inside the inner rotating sleeve 2, the counterweight plate 10 can be removed first, and then the fixed sleeve 9 is snap-connected to the anti-slip convex block 4. After that, the handwheel turntable 3 can be rotated to communicate the inner rotating sleeve 2 with the discharge port of the sampling cylinder body 1, and the solution inside the inner rotating sleeve 2 is poured out. During the pouring process of the solution, the solution is guided by the fixed sleeve 9, which makes it more convenient to pour out the solution.

[0027] As Figures 3 to 4 shown, a pushing block 11 is slidably connected inside the sampling cylinder body 1; the pushing block 11 is arranged at the position corresponding to the threaded hole; a spring is fixedly connected between the top of the pushing block 11 and the inner side wall of the threaded hole; during operation, when it is necessary to install the counterweight plate 10, after the threaded rod 101 is screwed into the threaded hole, the pushing block 11 is pushed by the spring, which can make the pushing block 11 push the threaded rod 101, so that the pressure between the threaded rod 101 and the threaded hole is greater, and thus the friction between the threaded rod 101 and the threaded hole is greater, making the threaded rod 101 more stable inside the sampling cylinder body 1.

[0028] As Figure 4 shown, a positioning block 12 is fixedly connected to the side wall of the inner rotating sleeve 2; the positioning block 12 is rotatably connected at the position inside the sampling cylinder body 1; during operation, when the inner rotating sleeve 2 rotates inside the sampling cylinder body 1, the rotation of the positioning block 12 is restricted by the sampling cylinder body 1, which can make the inner rotating sleeve 2 less inclined during rotation, making the rotation of the inner rotating sleeve 2 more stable.

[0029] As Figure 4 shown, a plurality of anti-wear balls 13 are provided between the sampling cylinder body 1 and the positioning block 12; the side walls of the anti-wear balls 13 are in contact with the side walls of the sampling cylinder body 1 and the positioning block 12; during operation, when the positioning block 12 rotates inside the sampling cylinder body 1, by providing anti-wear balls 13 between the sampling cylinder body 1 and the positioning block 12, the sliding friction between the sampling cylinder body 1 and the positioning block 12 can be changed into rolling friction, making the friction between the sampling cylinder body 1 and the positioning block 12 smaller, and thus reducing the wear between the sampling cylinder body 1 and the positioning block 12.

[0030] During operation, when it is necessary to sample the chemical solution, select the sampling cylinder 1 that is consistent with the liquid level of the solution, and insert the sampling cylinder 1 into the solution in a manner perpendicular to the liquid level. After the sampling cylinder 1 is completely inserted into the solution, the anti-slip protrusion 4 can be held and the handwheel dial 3 can be turned to connect the sampling cylinder 1 with the discharge port on the side wall of the inner rotating sleeve 2, so that the solutions at various places enter different storage cavities, so that samples can be taken from various places inside the solution at the same time. After the sampling is completed, the handwheel dial 3 can be turned to stagger the discharge port of the inner rotating sleeve 2 and the sampling cylinder 1, and the inner rotating sleeve 2 can be closed. After the sampling cylinder 1 is taken out of the solution, the sampling of the solution can be completed. After that, the solution inside the inner rotating sleeve 2 can be poured out and mixed, which can make the sampled solution more uniform and effectively avoid the precipitation of the solution, which may affect the detection.

[0031] When it is necessary to sample the solution, the gripping handle 7 can be held, and by fitting the ring 6 onto the external ball 5, the sampling cylinder 1 can be deflected without falling off, and the sampling cylinder 1 will gradually sag under the influence of gravity, so that the sampling cylinder 1 can remain vertical inside the solution, making the sampling of the solution more accurate, and under the influence of gravity on the counterweight plate 10, the sampling cylinder 1 can be made vertical at a faster speed.

[0032] When the solution inside the inner rotating sleeve 2 needs to be taken out, the counterweight plate 10 can be removed first, and then the fixed sleeve 9 can be buckled on the anti-slip protrusion 4, and then the handwheel turntable 3 can be rotated to connect the inner rotating sleeve 2 with the discharge port of the sampling cylinder 1, and the solution inside the inner rotating sleeve 2 can be poured out. During the process of pouring the solution, the solution can be guided by the fixed sleeve 9, which can make pouring the solution more convenient.

[0033] When the counterweight plate 10 needs to be installed, after the threaded rod 101 is screwed into the threaded hole, the pushing block 11 is pushed by the spring, so that the pushing block 11 can push the threaded rod 101, which can make the pressure between the threaded rod 101 and the threaded hole greater, thereby making the friction between the threaded rod 101 and the threaded hole greater, making the threaded rod 101 more stable inside the sampling cylinder 1.

[0034] When the inner rotating sleeve 2 rotates inside the sampling cylinder 1, the sampling cylinder 1 limits the rotation of the positioning block 12, so that the inner rotating sleeve 2 is less likely to tilt during the rotation, making the rotation of the inner rotating sleeve 2 more stable.

[0035] When the positioning block 12 rotates inside the sampling cylinder body 1, by arranging anti-wear balls 13 between the sampling cylinder body 1 and the positioning block 12, the sliding friction between the sampling cylinder body 1 and the positioning block 12 can be changed into rolling friction, so that the friction force between the sampling cylinder body 1 and the positioning block 12 is smaller, and thus the wear between the sampling cylinder body 1 and the positioning block 12 can be less.

Those skilled in the art should understand that the present invention is not limited by the above embodiments, and what is described in the above embodiments and the specification is only to illustrate the principle of the present invention.
