[0002] Food, soil and water quality are gradually polluted by industrial waste gas, wastewater and waste residue. Some people even use industrial wastewater directly to irrigate crops, resulting in the enrichment and accumulation of heavy metals such as cadmium, copper, arsenic, chromium, mercury, nickel, iron, aluminum, zinc, manganese and copper in the soil tillage layer, especially in urban suburbs. In addition, the large-scale use of inorganic chemical pesticides has caused the heavy metal content in vegetables and fish to seriously exceed the standard, which continues to accumulate in the human body, leading to chronic heavy metal poisoning in consumers. In order to detect the heavy metals contained in food, grain and oil, people have developed heavy metal detectors.

[0003] During the use of the grain and oil heavy metal detector, the solution to be tested needs to be placed in the test tube, and then placed in the test tank to achieve the effect of detecting heavy metals in the grain and oil.

The terms "include", "comprises", etc. used herein indicate the existence of the features, steps, operations and / or components, but do not exclude the existence or addition of one or more other features, steps, operations or components.

[0021] All terms (including technical and scientific terms) used herein have the meanings commonly understood by those skilled in the art, unless otherwise defined. It should be noted that the terms used herein should be interpreted as having a meaning consistent with the context of this specification, and should not be interpreted in an idealized or overly rigid manner.

[0022] In the embodiment, Figure 1-3 A positioning device for a grain and oil heavy metal detector is provided, comprising a body 1, characterized in that a printer 12 is fixedly connected to the top of the body 1, an inclined plane is provided on the top of the body 1, a detection slot 2 is provided on the inclined plane, a detection controller 11 is fixedly connected to the inclined plane, the detection controller 11 is located on the right side of the detection slot 2, and support legs 15 are fixedly connected to the four corners of the bottom of the body 1; the detection slot 2 is provided to facilitate the staff to perform heavy metal detection on grain and oil during use, and the detection controller 11 is provided to facilitate the staff to observe the detected data well during use. The printer 12 is provided to enable the measured data to be printed, thereby improving its use effect.

[0023] A plurality of detection ports 21 are provided at the inner bottom of the detection tank 2. A connection slot 22 is provided at the inner bottom of the detection tank 2. The connection slot 22 is located on the right side of the detection port 21. A positioning assembly 3 is rotatably connected in the connection slot 22. A cover plate 23 is fixedly connected to the upper end of an inner front wall of the detection tank 2. The connection slot 22 is provided and the positioning assembly 3 is rotatably connected therein, so that the staff can effectively facilitate the placement of the detection tube during use, thereby avoiding the occurrence of detection errors caused by the test liquid directly flowing into the detection port 21 due to bumps.

[0024] As the preferred technical solution of the utility model: a guide plate 31 is provided on the positioning assembly 3, and the right side of the guide plate 31 is rotatably connected with a connecting arm 32 and a supporting arm 33, and the other ends of the connecting arm 32 and the supporting arm 33 are both rotatably connected in the connecting groove 22, and the widths of the connecting arm 32 and the supporting arm 33 are adapted to the connecting groove 22. During use, the staff first opens the cover plate 23, and then pulls the handle 34 to extend the guide plate 31 from the detection groove 2. When the guide plate 31 is extended, the detection test tube can be placed in the positioning hole 35, and the guide plate 31 is pushed again to cause the connecting arm 32 and the supporting arm 33 to move with the guide plate 31. During the displacement of the guide plate 31, the detection test tube inside it will be inserted into the detection port 21, thereby effectively avoiding the situation where the test liquid is spilled into the detection port 21 due to the collision during the placement process.

[0025] As a preferred technical solution of the utility model: the support arm 33 is rotatably connected to the midpoint of one side of the guide plate 31, the connecting arm 32 is rotatably connected to the end point of one side of the guide plate 31, the connecting arm 32 is rotatably connected to the midpoint of the inner wall of the connecting groove 22, and the support arm 33 is rotatably connected to the end point of one inner wall of the connecting groove 22. This connection method effectively ensures that when the staff controls the handle 34 to pull the guide plate 31, the support arm 33 and the connecting arm 32 are driven to rotate, and the guide plate 31 can always remain parallel to the horizontal plane. When the support arm 33 and the connecting arm 32 rotate into the connecting groove 22, the guide plate 31 can just fit the inner bottom wall of the detection groove 2.

[0026] As a preferred technical solution of the utility model: a handle 34 is fixedly connected to the front of the guide plate 31, and a plurality of positioning holes 35 are provided on the guide plate 31, and the diameter of the opening of the positioning holes 35 is larger than the diameter of the opening of the detection port 21. This arrangement effectively facilitates the guide plate 31 to be well inserted into the detection port 21 during the displacement process toward the detection port 21.

[0027] As a preferred technical solution of the utility model: the mouth of the positioning hole 35 is fixedly connected to the limiting sleeve 36, and the limiting sleeve 36 is made of rubber. By setting the limiting sleeve 36 and setting it to be made of rubber material, it can play a good limiting effect on the test tube during use, ensuring that the guide plate 31 can be more stable during the displacement process.

[0028] As a preferred technical solution of the utility model: a power indicator light 14 is fixedly connected to the front of the body 1. By providing the power indicator light 14, the staff can well observe whether the device is powered on, ensuring its safety during use.

[0029] As a preferred technical solution of the utility model: the right end surface of the body 1 is provided with a connection port 13. The connection port 13 can effectively facilitate the staff to power it.

[0030] Working principle:

[0031] During use, the staff first opens the cover plate 23, and then pulls the handle 34 to extend the guide plate 31 from the detection slot 2. After the guide plate 31 is extended, the detection test tube can be placed in the positioning hole 35, and the guide plate 31 is pushed again to move the connecting arm 32 and the support arm 33 with the guide plate 31. During the displacement of the guide plate 31, the detection test tube inside it will be inserted into the detection port 21, thereby effectively avoiding the situation where the test liquid is spilled into the detection port 21 due to collision during the placement process. Then the staff can control the detection controller 11 to enable it to detect the detection liquid inside it. When the detection is completed, the staff can control the detection controller 11 to make the printer 12 print the detection results on paper.

[0032] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
