Description

Technical Field

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

[0002] A sampler is a sampling device. The samplers generally used are pipettes or syringes. Chemistry is a type of natural science. It mainly studies the composition, properties, structure and change laws of matter at the molecular and atomic levels, and creates new substances. The world is composed of matter, and there are mainly two forms of change: chemical change and physical change. Chemistry is one of the main methods and means for humans to understand and transform the material world. People use samplers to extract the solution before and after the reaction for comparison.

[0003] After searching, the "A Sampler for Chemical Detection" disclosed with patent number "202222106624.4" records a technical solution for adjusting the height of the syringe to prevent damage to the human body caused by chemical solutions. However, the technical solution recorded in the comparative document can only adjust the height of the syringe, but cannot adjust the angle of the syringe, which leads to certain limitations when experimenters use it.

[0004] Therefore, how to provide a liquid chemical reagent sampler for chemical testing that can adjust both the syringe height and the syringe angle has become a technical problem to be solved by technical personnel in this field. Utility Model Content

[0005] The technical problem to be solved by the utility model is how to provide a liquid chemical reagent sampler for chemical detection which can adjust both the height of the syringe and the angle of the syringe.

[0006] To achieve the above-mentioned purpose, the utility model provides a liquid chemical reagent sampler for chemical detection, comprising: a fixed base, a sampling mechanism is arranged on the fixed base, the sampling mechanism comprises a solution cylinder and a sampling syringe, the solution cylinder is arranged on the upper end surface of the fixed base, the sampling syringe is located above the solution cylinder, and the sampling syringe is connected to an adjustment mechanism for adjusting its height and angle, and the adjustment mechanism comprises an adjustment sleeve and an adjustment rod.

[0007] A non-slip pad is preset at the bottom of the fixed base, which increases the friction between the fixed support and the external laboratory table, avoiding the sliding deviation of the fixed base when in use. The solution cylinder and the sampling syringe adopt the existing structure in this field and are used for sampling liquid chemical reagents. The design of the adjustment sleeve and the adjustment rod can not only adjust the installation height of the sampling syringe according to actual needs, but also adjust the distance between the sampling syringe and the solution cylinder, and can adjust the angle of the solution cylinder.

[0008] Preferably, the upper end surface of the fixed base is preset with a limiting groove for placing the solution cylinder.

[0009] The design of the limiting groove ensures the stability of the solution cylinder when placed on the fixed base. This method is common knowledge and will not be described in detail.

[0010] Preferably, the adjustment sleeve is a cylindrical open structure, and a locking hole is preset on one side of the adjustment sleeve.

[0011] This design not only allows the adjustment sleeve to move up and down longitudinally along the support rod, but also allows the adjustment sleeve to rotate on the support rod, thereby achieving the purpose of adjusting the angle of the sampling syringe. The design of the locking hole makes it easy for the experimenter to lock and fix the adjustment sleeve and the support rod.

[0012] Preferably, the adjusting rod is transversely mounted on the adjusting sleeve, and the adjusting rod is a telescopic structure.

[0013] The fixed end of the adjusting rod and the adjusting sleeve are welded, and such a design ensures the stability of the connection. The adjusting rod adopts the existing bolt-fixed structure.

[0014] Preferably, the adjustment mechanism is connected to the sampling syringe via a supporting mechanism.

[0015] The supporting mechanism acts as a connecting member, so that the adjusting mechanism is connected to the sampling syringe.

[0016] Preferably, the support mechanism comprises a support plate, a support rod and a support sleeve;

[0017] The support plate is installed on one side of the fixed base, and the bottom of the support plate is flush with the bottom of the fixed base;

[0018] The support rod is vertically mounted on the upper end surface of the support plate, and the support rod is connected to the adjustment sleeve, and the support rod and the adjustment sleeve are slidably connected;

[0019] The support sleeve is installed at the movable end of the adjusting rod, the sampling syringe is fully surrounded in the support sleeve, and a locking hole is preset on one side of the support sleeve.

[0020] The support plate and the fixed bottom plate are welded, which ensures the stability of the fixed connection;

[0021] The support rod and the support plate are welded, which hinders the stability of their fixed connection;

[0022] The semi-enclosed design of the support sleeve and the sampling syringe ensures the stability of their connection, and the design of the locking hole makes it easy for the experimenter to lock and fix the adjustment sleeve and the support rod;

[0023] Preferably, the solid-liquid separation mechanism includes a liquid discharge port and a filter screen;

[0024] The discharge port is preset on one side of the solution cylinder;

[0025] The filter screen is installed inside the solution cylinder, and the installation height of the filter screen is higher than the preset height of the discharge port.

[0026] The drain port is used to discharge the remaining chemical reagents, and the filter is used to separate the solid and liquid of the reagents and filter the flocs produced during the solvent reaction, so as to facilitate the experimenters to detect the reagents and flocs.

[0027] The beneficial effects of the utility model are:

[0028] 1. When the utility model is in use, the design of the adjusting sleeve and the adjusting rod can not only adjust the installation height of the sampling syringe according to actual needs, but also adjust the distance between the sampling syringe and the solution cylinder, and can adjust the angle of the solution cylinder, which is conducive to popularization and use.

[0029] 2. When the utility model is in use, the filter screen cooperates with the design of the drain port to separate the solid and liquid of the reagent, thereby separating the liquid and floccules in the reagent, and then facilitating the experimenter to test the reagent and floccules, thereby ensuring the accuracy of the test results, reflecting the practicality of the device.
