Description

Technical Field

[0001] The utility model relates to the technical field of chemical product detection, in particular to a chemical product detection sampler. Background Art

[0002] Low-melting-point chemical products have a relatively low melting point during storage. At room temperature or in a high-temperature environment, they will melt into a paste. If they are left standing for a period of time, the concentration of the chemical product will be stratified, and the concentration will increase as you go down. This brings certain difficulties to sampling. Existing chemical product sampling often uses a medicine spoon or syringe structure, which makes it impossible to evenly sample chemical products at different locations of the sample at a single time.

[0003] The existing patent (authorization announcement number: CN216349708U) discloses a low-melting-point chemical product detection sampler, which belongs to the field of chemical product sampling technology. A low-melting-point chemical product detection sampler includes a handheld block, a mixing chamber is opened inside the sampling block, a rack is arranged inside the square chamber, the motor output end passes through the inner wall of the machine chamber to extend to the inside of the circular chamber and is sleeved with a crankshaft, and the lower end of the middle shaft passes through the inside of the handheld block to extend to the inside of the arc groove and is provided with a sampling component. The tight fit between the structures allows the device to be deeply inserted into it when in use. By controlling the swing-out sampling of the sampling component, two layers can be sampled at the same time, and the sampling amount is constant. The device can perform multiple samplings on the same layer to control the sampling amount, avoiding the situation where both hands are working at the same time and the eyes have to observe, which is prone to shaking and leads to different sampling amounts for each layer, ensuring the proportion of the sampling amount, thereby ensuring the accuracy of the mixed detection results. The prior art has the following problems: 1. Although the existing chemical product detection sampler can perform stratified sampling, the opening of the sampling tube is small. When the chemical sample is discharged after sampling, part of the paste chemical sample in the sampling tube will remain in the sampling tube and cannot be squeezed out, making it difficult to clean the chemical sample remaining in the sampling tube; 2. The existing sampler is handheld, and the height of the sampling tube on the sampler is fixed. Therefore, the depth of the sampling tube into the chemical product is completely controlled manually, which is easily affected by external factors and shakes, and the depth is also difficult to adjust.

[0010] Preferably, a transmission belt is movably connected between the two limiting rings, the limiting ring and the pulley are movably connected through the transmission belt, a rotating shaft passes through the middle of the pulley, and a knob is fixedly connected to the top of the rotating shaft.

[0011] Preferably, two guide columns are fixedly connected to the top of the rotating table, the top ends of the two guide columns are inserted into the inside of the guide groove, the guide groove is opened inside the rotating column, and the middle part of the top end of the rotating column is rotatably connected to the lifting column through a bearing.

[0012] Preferably, the rotating table is annular, and the top surface of the rotating table and the top surface of the base are located in the same plane. The rotating table is rotatably connected to the middle of the top surface of the base.

[0014] Compared with the prior art, the beneficial effects of the utility model are:

[0015] The detection sampler proposed by the utility model drives the sealing plate to rise by shortening the telescopic rod, opens the sampling chamber, and facilitates cleaning of the interior of the sampling chamber. The base is inserted into the bottom of the barrel filled with chemical products, and then the motor is started to drive the main bevel gear to rotate. When the main bevel gear rotates, it drives the adjusting screw to rotate through the secondary bevel gear. The adjusting screw drives the lifting column to rise and fall. The lifting column drives the sampling column to rise and fall through the outer rotating column, thereby changing the height of the sampling chamber on one side of the sampling column in the chemical sample. Because the sampler base contacts the bottom of the barrel, the sampler has a fulcrum, which is more stable than traditional handheld samplers, and does not rely on human hands to drive the depth of the entire sampler in the chemical product, so it is more accurate in layered sampling.
