Detailed Description

The utility model is further described with reference to the accompanying drawings and specific examples:

the utility model discloses a multi-specification sampling tube adapter, which is shown in fig. 1 and 2, and is connected to a fixed tube of a sampling device, and comprises an adapter body 1, wherein the adapter body 1 and the fixed tube of the sampling device are detachably connected by virtue of threads, annular connecting units are arranged on the adapter body 1, a plurality of connecting units with different diameters are sequentially connected to form a stepped tubular structure, each connecting unit comprises a threaded connecting part 2, a sealing part and a locking ring 3, the locking ring 3 and the threaded connecting part 2 are detachably connected by virtue of threads, the locking ring 3 is sleeved outside the threaded connecting part 2 and the sealing part, and an annular clamping cavity for clamping the sampling tube is formed between the inner side surface of the locking ring 3 and the outer side surface of the sealing part.

When the adapter is used, the adapter body is connected with the fixed pipe of the sampling device valve unit through the screw hole arranged at the upper end of the adapter body, when the sampling pipe is required to be connected with the adapter, the connecting unit corresponding to the caliber of the sampling pipe on the adapter body is detached firstly, specifically, as shown in figure 2, the locking ring of the connecting unit is screwed down, the sampling pipe penetrates through the inner ring of the locking ring, then the sampling pipe is inserted into the sealing part of the connecting unit, and then the locking ring is screwed with the screw connection part of the connecting unit, so that the sampling pipe is clamped in an annular clamping cavity formed between the inner side surface of the locking ring 3 and the outer side surface of the sealing part to clamp the sampling pipe, locking is completed, the sampling pipe adopts a threaded steel wire hose or a common PVC hose, the locking is completed through clamping of the locking ring and the sealing part, only the locking ring is involved in the whole process, the step of replacing the adapter is reduced, and the sampling efficiency is improved.

Two groups of connecting units are arranged as shown in fig. 1 and 2, and multiple groups of connecting units can be arranged according to actual needs, so that the sampling pipes with more dimensions can be connected for use.

Further, as shown in fig. 5, the inner side surface of the locking ring 3 is obliquely arranged to be a bell mouth structure, and the annular clamping cavity forms an annular groove structure with a narrow outer side and a wide inner side by means of the bell mouth structure.

As shown in fig. 5, the sampling tube is extruded in the annular clamping cavity through the horn-shaped structure at the inner side of the locking ring, so that falling off is avoided, and the stability and safety of the use of the sampling tube are ensured.
