The sampling head of air sampler can be rapidly compacted and detached, which is convenient for placing and taking out the filter paper; the connecting part has good air tightness; the sampling head of air sampler has strong practicability.
Description
Technical field
The utility model belongs to environment sampling apparatus field, relates in particular to a kind of can closing tightly and the air sampler sampling head that shirks.
Background technology
Along with the development rapidly of economy, people's living standard is also brought sizable pollution to environment in fast lifting.Advance the enhancing gradually of people's environmental consciousness over a little years, more and more pay attention to the sampling monitoring to environment.Monitoring is the big important component part of one in the environment test sample to the air test sample; To air sampling the time, often utilize air sampler to wear the air sampling head and carry out operation, be that driving source sucks sampling head with air with the air sampler, the materials such as filter paper of sampling head inside filter air, again the foreign material on the filter paper are separated detection.The common version of sampling head is that an end is air intake opening, and the other end is the gas outlet that is connected with sampling thief, and filter paper is placed on sampling head inside, and therefore requiring the sampling head middle part is detachable separated structures, is convenient to place filtrate such as filter paper.The middle part of traditional sampling head all is set to screw connection structure, but the quite inconvenience when closing and shirk of the sampling head of this structure.
Summary of the invention
The purpose of this utility model is the shortcoming that overcomes prior art, provides a kind of simple and reasonable, can close air sampler sampling head tight and that shirk.
For solving the problems of the technologies described above, concrete technical scheme of the present utility model is as follows:
A kind of air sampler sampling head comprises the air inlet head and a two parts of giving vent to anger, and it is characterized in that:
Described air inlet head mainly is divided into two parts, is divided into leading portion tapered snorkel section and back thin walled tube linkage section;
Pipe section, middle taper escape pipe section and end thread section before the described head of giving vent to anger is divided into;
Thin walled tube linkage section inside surface and a described preceding pipe section outside surface of giving vent to anger are to cooperating behind the described air inlet head;
Thin walled tube linkage section inside surface is provided with fixture block behind described air inlet head;
A described preceding pipe section end face of giving vent to anger is provided with the gathering sill that is complementary with described fixture block; Also be provided with the screens groove that communicates with described gathering sill on the pipe section outer round surface before the described head of giving vent to anger, described fixture block is stuck in the described screens groove.
Further, pipe section inside surface end is provided with the stop bit platform before the described head of giving vent to anger.
Further, described fixture block thin walled tube linkage section inside surface behind the air inlet head is circumference uniform distribution.
Advantage of the present utility model is: can close tight rapidly and shirk, be convenient to laying and take out filter paper; The coupling part possesses good air tightness simultaneously; Has stronger practicality.
[0008] description of drawings
Fig. 1 is the utility model air inlet header structure synoptic diagram;
Fig. 2 is the utility model header structure synoptic diagram of giving vent to anger.
Embodiment
Come the utility model is further described below in conjunction with accompanying drawing.
Shown in Fig. 1 and 2, the utility model comprises a kind of air inlet 1 and 2 two parts of giving vent to anger of comprising; Described air inlet 1 mainly is divided into two parts, is divided into leading portion tapered snorkel section 1a and back thin walled tube linkage section 1b; Described give vent to anger 2 be divided into before pipe section 2a, middle taper escape pipe section 2b and the end thread section 2c of being convenient to be connected with air sampler; Thin walled tube linkage section 1b inside surface and a described preceding pipe section 2a outside surface of giving vent to anger are to cooperating behind the described air inlet head; Thin walled tube linkage section 1b inside surface is provided with the fixture block 1b1 that is circumference uniform distribution behind described air inlet head; A described preceding pipe section 2a end face of giving vent to anger is provided with the gathering sill 2a1 that is complementary with described fixture block 1b1; Also be provided with the screens groove 2a2 that communicates with described gathering sill 2a1 on the pipe section 2a outer round surface before the described head of giving vent to anger, described fixture block 1b1 is stuck in the described screens groove 2a2.
The utility model is when concrete the use, pipe section 2a inside surface end is provided with stop bit platform 2a3 and places one deck filter paper before the described head of giving vent to anger earlier, the inside surface of thin walled tube linkage section 1b behind the described air inlet head is realized fitting with the preceding pipe section 2a outside surface of the head of giving vent to anger, fixture block 1b1 is aimed at gathering sill 2a1 on the preceding pipe section 2a end face of giving vent to anger, air inlet 1 is inwardly pushed along gathering sill 1a1, when fixture block 1b1 slides into the gathering sill bottom, rotation air inlet 1, fixture block 1b1 is snapped in the screens groove 2a2, just realized air inlet 1 with give vent to anger 2 close tightly, close simultaneously and have a higher impermeability after tight.When needs take out filter paper, only need the past opposite spin certain angle of air inlet head, directly pull out air inlet 1 back then and just can take out filter paper; It is convenient rapidly to shirk.
The utility model can close tight rapidly and shirk, and is convenient to laying and take out filter paper; The coupling part possesses good air tightness simultaneously; Has stronger practicality.
