[0021] 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. Example

[0022] Existing chemical liquid samplers typically use an extraction method for sampling. However, this extraction method is prone to leakage during sample transfer. Please refer to [the relevant documentation / reference needed]. Figures 1-4The embodiment provides a portable chemical liquid sampler that can effectively improve the leakage prevention effect of the sample during the liquid sampling process. The portable chemical liquid sampler includes a sampling tube 1, a sampling device installed at the top of the sampling tube 1, a limiting device installed in the middle of the sampling tube 1, and a sealing device installed in the middle of the limiting device.

[0023] The sampling device includes a sampling structure and an auxiliary structure, with the sampling structure installed in the middle of the auxiliary structure. The sampling structure includes a knob 105, with an adjusting cylinder 106 connected to its bottom. An adjusting rod 107 is connected to the bottom of the adjusting cylinder 106, and a piston plate 108 is connected to the bottom of the adjusting rod 107. A sealing ring 109 is installed on the outer surface of the piston plate 108, and a telescopic rod 110 is installed near the right end of the top surface of the piston plate 108. The auxiliary structure includes a sampling cylinder 101, with handles 103 installed on the left and right sides of the middle of the outer surface of the sampling cylinder 101. An observation window 102 is installed in the middle of the front of the outer surface of the sampling cylinder 101, and a fixing bracket 104 is installed at the top of the sampling cylinder 101.

[0024] The outer surface of the adjusting cylinder 106 is connected to the middle of the top surface of the fixed frame 104 via a bearing near the top. The top of the outer surface of the adjusting rod 107 is threaded to the bottom of the inner part of the adjusting cylinder 106. The outer surface of the sealing ring 109 and the outer surface of the piston plate 108 are slidably connected to the inner wall of the sampling cylinder 101. The top of the telescopic rod 110 is connected to the top of the inner part of the sampling cylinder 101. The outer surface of the adjusting cylinder 106 is rotatably connected to the middle of the top of the sampling cylinder 101. The middle of the bottom of the sampling cylinder 101 is connected to the top of the sampling tube 1.

[0025] By using the sampling device, the piston plate 108 is displaced by the threaded connection between the adjusting cylinder 106 and the adjusting rod 107, thereby extracting the liquid sample and effectively preventing leakage of the liquid sample.

[0026] When sampling liquid samples using the sampling cylinder 101, rotating the knob 105 drives the adjusting cylinder 106 to rotate. The adjusting cylinder 106 is threadedly connected to the adjusting rod 107, thereby adjusting the overall length of the adjusting cylinder 106 and the adjusting rod 107. At the same time, the installation of the telescopic rod 110 ensures the lifting and lowering of the piston plate 108. The sealing effect of the piston plate 108 and the sealing ring 109 creates negative pressure at the bottom of the sampling cylinder 101 to extract the liquid sample. Meanwhile, the observation window 102 and the scale on the outside of the observation window 102 improve the accuracy of sample extraction. After the sample is extracted, the adjusting cylinder 106 is connected to the fixing frame 104 through the bearing, and the adjusting rod 107 is threadedly connected to the adjusting cylinder 106, preventing leakage of liquid samples due to compression during sample transfer. Example

[0027] Based on Implementation 1, existing technologies still have the problem of insufficient sealing after sample extraction, leading to sample leakage during liquid sample transfer and transport. Please refer to... Figures 1-4 This embodiment provides a portable chemical liquid sampler that effectively solves the problem of sample leakage. The portable chemical liquid sampler includes a limiting device comprising a sealed box 201. Limiting rails 202 are installed in the middle of the front and back sides inside the sealed box 201. A slider 203 is connected to the middle of the limiting rails 202. A limiting plate 204 is installed at the left end of one of the two limiting rails 202 that are close to each other. The top and bottom surfaces of the sealed box 201 are fixedly connected to the outer surface of the sampling tube 1. The outer surface of the slider 203 is slidably connected to the inner wall of the convex groove in the middle of the limiting rail 202.

[0028] The sealing device includes a threaded rod 301, with a limiting block 302 connected to the left end of the threaded rod 301. A limiting cylinder 303 is connected to the outer surface of the limiting block 302, and a sealing plate 304 is connected to the left end of the limiting cylinder 303. The outer surface of the threaded rod 301 is threadedly connected to the middle right side of the sealing box 201. The outer surface of the limiting block 302 is connected to the limiting cylinder 303 through a limiting groove for limited rotation. The front and back of the sealing plate 304 are fixedly connected to the side of the slider 203 away from the limiting rail 202. The top and bottom surfaces of the sealing plate 304 are slidably and sealingly connected to the middle of the sampling tube 1.

[0029] By setting up limiting devices and auxiliary devices, the threaded rod 301 drives the sealing plate 304 to move, and the limiting plate 204 limits the movement of the sealing plate 304, thereby ensuring the liquid sampling and sealing and leak prevention effect.

[0030] When extracting samples, the threaded rod 301 is rotated. Since the outer surface of the threaded rod 301 is threadedly connected to the middle right side of the sealing box 201, and the left end of the threaded rod 301 is connected to the limiting cylinder 303 through the limiting block 302, the limiting cylinder 303 is fixedly connected to the middle right end of the sealing plate 304, thereby driving the sealing plate 304 to move, so that the left side of the sealing plate 304 abuts against the limiting plate 204, thereby opening a through hole in the middle of the sealing plate 304 and coinciding with the middle of the sampling tube 1 to ensure smooth sampling. After sampling, the threaded rod 301 is flipped, thereby driving the sealing plate 304 to move to the right, so that the right side of the limiting cylinder 303 abuts against the right side inside the sealing box 201, thereby sealing the sampling tube 1 with the sealing plate 304, ensuring the sealing after sampling, and effectively preventing leakage during the transfer and carrying of liquid samples.
