Description

Technical Field

[0001] This utility model relates to the field of sampling technology for daily chemical products, and specifically to a sampling device for testing daily chemical products. Background Technology

[0002] Liquid sampling is a crucial step in the production and quality inspection of daily chemical products. The accuracy and efficiency of sampling directly impact the reliability of product quality inspection and production efficiency. Traditional liquid sampling methods typically use pinhole sampling devices, with the following operation: 1. The operator inserts one end of the pinhole sampling device into the liquid to be tested; 2. By pulling the piston, the liquid is drawn into the sampling device; 3. The sampling device is removed, completing the liquid sampling. However, this traditional pinhole sampling device has significant technical limitations: it can only sample the surface of the liquid and cannot sample liquids at different depths within the storage tank, resulting in unrepresentative sampling results.

[0003] Patent publication number "CN 213600410 U" includes a storage cylinder with an inlet and an outlet. A flow-blocking plug for sealing the outlet is located inside the storage cylinder. A handle is connected to the storage cylinder, and a support rod for driving the flow-blocking plug closer to or away from the outlet is movably inserted within the handle. A drive assembly for driving the support rod axially is screwed onto the handle. This application has the effect of facilitating operator control of sample release flow rate.

[0004] The patented device, through the cooperation of a handle, support rod, and drive assembly, enables sampling at different depths within a storage tank. However, the device still has the following shortcomings: each sampling can only obtain a sample from one depth point. If multiple sampling points are required, the liquid inside the device must first be removed, and then the device must be cleaned to prevent residual liquid from affecting the accuracy of the next sampling. This sampling method not only increases the number of operating steps and labor intensity but also reduces sampling efficiency. Utility Model Content

[0027] To address the technical problems in the background section, the following sampling device for testing daily chemical products is provided:

[0028] Combination Figures 1-6As shown, the present invention provides a sampling device for testing daily chemical products, including a sampling plate 1; square holes 2 are evenly spaced on one side of the sampling plate 1, a sampling device 3 is connected to one side of the sampling plate 1 through the square holes 2, a pull rod assembly 4 is installed on the other side of the sampling plate 1, an extension plate 5 is fixedly connected to one side of the sampling plate 1 above the square holes 2, and a clamping bolt 6 is threaded into the extension plate 5; the sampling device 3 includes a transparent sampling bottle 31, an L-shaped rod 32 is fixedly connected to the circumferential surface of the transparent sampling bottle 31, one end of the L-shaped rod 32 is inserted into the square holes 2, one end of the clamping bolt 6 is in contact with one side of the L-shaped rod 32, a piston assembly 33 is installed inside the transparent sampling bottle 31, a blocking assembly 34 is installed on the upper part of the inner cavity of the transparent sampling bottle 31, a valve body assembly 35 is threadedly connected to the lower part of the bottom surface of the transparent sampling bottle 31, and scale lines 36 are provided on the surface of the transparent sampling bottle 31. The piston assembly 33 includes a piston 331, which is slidably connected inside the transparent sampling bottle 31.

[0029] By cooperating with the piston 331, rectangular sleeve 332, hook rod 334, hook hole 35 and reset damping rod 333 in the piston assembly 33, it is convenient to take different amounts at different positions at the same time when sampling is performed later.

One end of the positioning bolt 341 is rotatably connected to a positioning plate 342. The positioning plate 342 slides on the surface of the rectangular sleeve 332.

[0031] By using the positioning bolt 341 in the blocking assembly 34 in conjunction with the positioning plate 342, the piston 331 can be blocked, thus enabling quantitative sampling. Example 2

[0032] like Figures 1-6 As shown, based on the above embodiments, this embodiment further provides the following:

[0033] The valve body assembly 35 includes a cylinder 351. The lower part of the inner cavity of the transparent sampling bottle 31 is threadedly connected to the cylinder 351.

Example 3

[0035] like Figures 1-6 As shown, based on the above embodiments, this embodiment further provides the following:

[0036] The pull rod assembly 4 includes a force-bearing rod 41, which is fixedly connected to one side of the sampling plate 1.

[0037] By cooperating with the pull rod 42, the first hook rod 45, the pull rod 47, the locking bolt 46, and the second hook rod 48 in the pull rod assembly 4, the two sets of piston assemblies 33 can be pulled, thus enabling sampling of the two transparent sampling bottles 31.

[0038] Working principle and usage process of this utility model:

[0039] In use:

[0040] When in use, first install the first set of sampling devices 3;

[0041] Before installation, first, according to the sampling amount, rotate the positioning bolt 341. The positioning bolt 341 will drive the positioning plate 342 to slide on the surface of the rectangular sleeve 332. At this time, the staff will observe the scale line 36. When the positioning plate 342 moves to the designated scale line 36, stop rotating the positioning bolt 341. Then, the staff will screw the valve body assembly 35 to the liquid inlet of the transparent sampling bottle 31.

[0042] At this point, the transparent sampling bottle 31 is installed. During installation, first, one end of the L-shaped rod 32 is inserted into the corresponding square hole 2. At the same time, one end of the second hook rod 48 needs to be inserted into the hook hole 335. After insertion, the operator tightens the clamping bolt 6. This fixes one end of the L-shaped rod 32 in the square hole 2, thus fixing the first set of sampling devices 3 onto the sampling plate 1. After fixing, the operator rotates the locking bolt 46. When the locking bolt 46 rotates, it fixes the pulling rod 47 and the pulling sleeve rod 42 together.

[0043] After fixing, the second set of sampling devices 3 is installed. The second set of sampling devices 3 is installed in the same way as the first set of sampling devices 3. The difference is that the first set of sampling devices 3 and the second set of sampling devices 3 are installed on the sampling plate 1 to ensure the distance between them so that sampling can be carried out at different locations later. At the same time, the hook hole 335 in the second sampling device 3 is inserted and connected to the first hook rod 45.

[0044] After all connections are made, the operator inserts it into the liquid to be tested, positioning the first sampling device 3 and the second sampling device 3 at different positions on the upper and lower levels. The operator then pulls the pulling sleeve 42, which moves the pulling rod 47, the first hook rod 45, and the second hook rod 48. As the first hook rod 45 and the second hook rod 48 move, they move the hook rod 334, the reset damping rod 333, the rectangular sleeve 332, and the piston 331. When the piston 331 moves, the vacuum lifts the sealing plug 354, allowing the liquid to flow along the periphery of the sealing plug 354 into the transparent sampling bottle 31. As the piston 331 moves... When piston 331 moves to the side of positioning plate 342 and is blocked, piston 331 will stop moving. At the same time, sealing plug 354 will seal cylinder 351 under the action of spring 356 to prevent external liquid from flowing in or internal liquid from flowing out. If at this time, the other set of pistons 331 is not in contact with positioning plate 342, the hook rod 334 of the blocked piston 331 will stretch and reset damping rod 33 to ensure that piston 331 does not move. When the hook rod 334 moves, it can also make the other set of pistons 331 move inside transparent sampling bottle 31, so that both sets of transparent sampling bottles 31 can collect the specified amount of sample, so as to achieve the same time, different positions, different amounts or the same amount.

[0045] By removing the valve assembly 35 from the transparent sampling bottle 31, the sample inside the transparent sampling bottle 31 can be taken out, which facilitates subsequent testing.
