Technical Field

[0001] The utility model relates to the field of chemical safety detection, in particular to a chemical safety detection device which is convenient to adjust. Background Technique

[0002] Chemical engineering is the abbreviation of "chemical technology", "chemical industry", "chemical engineering", etc. All technologies that use chemical methods to change the composition, structure or synthesize new substances belong to chemical production technology, that is, chemical technology, and the obtained products are called chemical products or chemical industrial products.

[0003] During chemical safety detection, chemical reagents are generally inside test tubes or reagent bottles, and then sampling is carried out and detection processing is carried out.

[0004] Since there are many types of chemical reagents, this leads to a relatively large variety of containers for holding chemical reagents, and the levels of the chemical reagent volumes inside each container are different. This leads to the situation that when the detection device samples, it is easy for the sampling head to be difficult to immerse into the chemical reagent, or for the sampling head to be difficult to extend into the container.

A detection mechanism is installed at the upper end of the column 2. A placing groove 4 is provided on the front side of the upper end of the column 2. A connecting mechanism is also included.

[0027] Two underframes 11 are fixed to the lower end of the base 1. A plurality of fixed bolts 12 are arranged in the middle of the underframes 11; the device can be fixed to a suitable position through the fixed bolts 12.

[0028] The detection mechanism includes a mounting plate 21 which is fixed to the upper end of the column 2. A detection device 22 is installed at the upper end of the mounting plate 21. A small pump body 23 is installed at the lower end of the detection device 22. A telescopic hose 24 is fixed to the input end of the small pump body 23. The bottom of the telescopic hose 24 is of a metal tube structure, and the outer wall of the metal tube structure at the bottom of the telescopic hose 24 is processed with external threads. Through the external threads of the metal tube structure at the bottom of the telescopic hose 24, the telescopic hose 24 can be connected to the communication structure. Then, after starting the small pump body 23, the chemical reagent can be pumped into the detection device 22 for detection processing.

[0029] The communication mechanism includes a collar 3 which is rotatably connected to the outer circle of the column 2. A nine-branch rotating frame 31 is fixed to the outer circle of the collar 3. The nine-branch rotating frame 31 is semicircularly arranged, and the distance between every two adjacent branches of the nine-branch rotating frame 31 is the same. Sliding sleeves 32 are slidably connected to the nine branches of the nine-branch rotating frame 31. The diameters of the sleeves 32 on the three branches on one side of the nine-branch rotating frame 31 are the same. The diameters of the sleeves 32 on the three middle branches of the nine-branch rotating frame 31 are smaller than those of the three sleeves 32 on one side of the nine-branch rotating frame 31. The diameters of the sleeves 32 on the three branches on the other side of the nine-branch rotating frame 31 are smaller than those of the three sleeves 32 in the middle of the nine-branch rotating frame 31. The lengths of the three sleeves 32 with the same diameter are divided into three types: long, medium, and short. The length difference between the long sleeve 32 and the medium sleeve 32 is 5 cm, and the length difference between the medium sleeve 32 and the short sleeve 32 is 5 cm. The lower end of each sleeve 32 is sharpened. A spring 33 is arranged around the sleeve 32.

Through the rotational connection between the collar 3 and the column 2, rotate the nine-branch rotating frame 31 on the outer circle of the collar 3 to make the suitable sleeve 32 located above the bottle mouth of the container. Then, connect it to the sampling structure through the internal threads on the inner wall of the upper half of the connecting sleeve 34.

In this way, the applicability of the device can be better, and because the lower end of the sleeve 32 is sharpened, it is also more convenient to sample some chemical reagent bottles sealed with rubber stoppers at the bottle mouth.

[0030] Working principle: Before the device operates, first adjust the device according to the bottle mouth of the chemical reagent container, the height of the container, and the volume of the chemical reagent. Through the rotational connection between the collar 3 and the column 2, rotate the nine-branch rotating frame 31 on the outer ring of the collar 3 to make the appropriate cannula 32 located above the bottle mouth of the container. Subsequently, connect the internal thread on the inner wall of the upper half of the connecting sleeve 34 to the external thread of the metal tube structure at the bottom of the telescopic hose 24. After the preparation work is completed, press down the cannula 32 located directly above the bottle mouth of the container, so that the lower end of the cannula 32 extends into the chemical reagent. Then, the small pump body 23 can be started to sample the reagent. Finally, the chemical reagent is detected by the detection device 22. In this way, the applicability of the device can be better, and since the lower end of the cannula 32 is sharpened, it is also convenient to sample some chemical reagent bottles sealed with rubber stoppers at the bottle mouth.
