Problems solved by technology
Most of the existing filling methods use to place the weighed and impregnated filler (silica gel or activated carbon) on a thin paper sheet, and pour the filler into the sampling tube through the paper sheet. Due to the small mouth of the sampling tube, it is inevitable that the There is a situation where the filler is scattered outside, causing the quality of the filler in the filled sampling tube to fail to meet the requirements; in addition, it is necessary to fully compress the filler filled in the sampling tube when filling. At present, most of the filling personnel hold the slender object Stretch into the sampling tube and press back and forth. It is difficult to grasp the position or strength of the pressing. If the force is too small, the silicone in the sampling tube will not be pressed firmly. Extrusion from the other end; moreover, the existing operation process is more cumbersome, which increases the workload and wastes time

The invention relates to a clamping, fixing and filling device for a glass sampling tube. The device is characterized in that a plurality of propping columns are arranged in the middle above a base in a spaced manner, a round bugle is arranged at the top end of each propping column, a fixing rod is arranged on one side above the base and sleeved with a sleeve, a tightly screwing button is arranged on the sleeve which is fixed on the fixing rod through the tightly screwing button, a flexible support rod is arranged on the outer side wall of the sleeve on the opposite side of the tightly screwing button, a free end of the flexible support rod is connected with the middle of the outer side of a horizontal arc-shaped plate, the height and the angle of a funnel and a propping rod can be adjusted conveniently according to requirements, free switching between filler filling and filler pressing is realized, accurate filling of the filler is realized, scattering of the filler is avoided, staged filling is facilitated, the condition that the filler scatters outside the sampling tube due to smaller sampling tube mouth during filling of the filler is avoided, and the condition that the quality of silica gel in the sampling tube after filling does not meet the requirement is avoided effectively.
Description
Technical field: [0001] The invention relates to a clamping and fixing filling device for a glass sampling tube. Background technique: [0002] At present, when sampling occupational disease hazards on site, according to national standards, some hazards such as formic acid need to be impregnated with glass sampling tubes before sampling. After soaking in the liquid, put the filling material (silica gel or activated carbon) impregnated quantitatively back into the glass sampling tube. Most of the existing filling methods use to place the weighed and impregnated filler (silica gel or activated carbon) on a thin paper sheet, and pour the filler into the sampling tube through the paper sheet. Due to the small mouth of the sampling tube, it is inevitable that the There is a situation where the filler is scattered outside, causing the quality of the filler in the filled sampling tube to fail to meet the requirements; in addition, it is necessary to fully compress the filler fille...
