DETAILED DESCRIPTION

[0019] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0020] In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as a limitation on the present invention.

[0021] Reference Figure 1-3 , an environmental sample preservation device, including a cup body 1, a handle 10 is fixedly connected to the side wall of the cup body 1, a circular groove 11 is fixedly opened on the top side wall of the handle 10, and the side wall of the circular groove 11 is roughened, mainly to facilitate the holding and fixing of the cup body 1 during the sampling process to prevent the cup body 1 from tipping over during the sampling process, a scale bar 12 is arranged on the side wall of the cup body 1, mainly to facilitate the confirmation of whether the amount of water sample sampling meets the requirements and improve the efficiency of water sample sampling, a fixed plate 2 is arranged inside the cup body 1, a circular groove 18 is penetrated on the fixed plate 2, four symmetrically arranged fixed rods 3 are fixedly connected to the bottom side wall of the fixed plate 2, the four fixed rods 3 are fixedly connected to sliding rods 4, and the four sliding rods 4 are fixedly connected to a sealing plate 6 at one end away from the fixed rods 3, and a spring 5 is fixedly sleeved on the side wall of the four fixed rods 3, and one end of the four springs 5 ​​is fixed to the side wall of the fixed plate 2.

[0022] The other ends of the four springs 5 ​​are fixed to the top side wall of the sealing plate 6. A conical block 7 is fixedly arranged on the top of the sealing plate 6. A conical groove 8 is arranged on the bottom side wall of the fixed plate 2, and the conical groove 8 and the conical block 7 are matched with each other. A guide groove 9 is opened on the top side wall of the circular groove 18, mainly for guiding during the sampling process. A circular plate 13 is fixed to the top of the cup body 1, and a threaded groove 14 is fixedly opened on the side wall of the circular plate 13. A fixed cover 15 is arranged on the top of the cup body 1, and a threaded block 16 is arranged on the inner wall of the fixed cover 15, and the threaded block 16 and the threaded groove 14 are matched with each other, mainly to form a protective structure for the water sample inside the cup body 1 to prevent the sample cup from tipping over during transportation, causing the internal water sample to spill out, and avoiding repeated sampling of the water sample. A plurality of strip blocks 17 are arranged in an annular manner on the side wall of the fixed cover 15, and the side walls of each strip block 17 are roughened, mainly to facilitate the rotation of the fixed cover 15 and increase the friction during the rotation process.

[0023] In the utility model, when conducting water sample testing, the person to be tested needs to discharge the water sample into the interior of the cup body 1. During the discharge process, the water sample enters from the top of the cup body 1 and falls onto the conical block 7 on the sealing plate 6. Under the action of the gravity of the water sample, the conical block 7 is squeezed to make the sealing plate 6 move away from the fixed plate 2. During this movement, the sliding rod 4 slides on the fixed rod 3, and the spring 5 is stretched by force at this time, and the water sample enters the interior of the cup body 1. Then, the scale bar 12 on the cup body 1 is used to judge whether the amount of the water sample meets the detection requirements.

[0024] When the amount of water sample inside the cup body 1 meets the detection requirements, the discharge of the water sample is stopped, and the conical block 7 is no longer squeezed. Under the action of each spring 5, the sliding rod 4 slides and resets on the fixed rod 3, so that the conical block 7 is abutted against the side wall of the conical groove 8, and a water sample sealing processing device is formed inside the sample cup to prevent the water sample to be detected in the sample cup from directly contacting the air, thereby improving the authenticity of the water sample detection. Finally, after the water sample sampling is completed, the fixed cover 15 is fixed on the circular plate 13 through the rotation of the threaded groove 14 and the threaded block 16, forming a protective structure for the water sample that needs to be detected inside, preventing the sample cup from tipping over during transportation, causing the water sample inside to spill out, and avoiding repeated sampling of water samples.

[0025] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
