Description
Technical field
The present invention relates to a kind of air sampler, particularly relate to a kind of air sampler that does not need tripod to support.
Background technology
Existing air sampler must be by tripod, air sampler adjustment is installed on tripod, and be adjusted to suitable height and sample, tripod is heavier, carry inconvenience, brought a lot of troubles to sampling work, prior art not yet works out the air sampler that does not need tripod.
Summary of the invention
The technical problem to be solved in the present invention be to provide a kind of simple in structure, cost is low, easy and simple to handle, do not need tripod support air sampler.
A kind of air sampler, comprise four gas circuit air samplers, also comprise expansion link, described expansion link is connected with the air inlet pipeline of described four gas circuit air samplers by connecting link, the hollow circular cylinder that described expansion link is increased successively by three diameters is socketed to form, and is followed successively by expansion link, middle expansion link and lower expansion link, and the bottom of described lower expansion link is connected with described connecting link, described connecting link is hollow circular cylinder, and the top of expansion link is provided with at least one air admission hole on described.
Air sampler of the present invention, wherein said upper expansion link, middle expansion link and lower length of telescopic bar are 0.3m, and wall thickness is 1cm.
Air sampler of the present invention, the diameter of wherein said upper expansion link is 10cm, and the diameter of middle draw-tube is 12cm, and the diameter of upper expansion link is 10cm.
Air sampler of the present invention, wherein said air admission hole is multiple, and each air admission hole arranges in the tube wall medium dip of upper expansion link.
Air sampler of the present invention, wherein said air admission hole is 6.
Air sampler of the present invention, the diameter of wherein said connecting link is 14cm.
Air sampler difference from prior art of the present invention is: air sampler of the present invention adopts split-type design, assembling is simple, easy to maintenance, overall length is 0.9m, is installed to after air sampler, can be placed directly on ground and sample, air admission hole height is between 1.2-1.5m, can reach height of sampling completely, compared with similar products, remove this annex of tripod.
Below in conjunction with accompanying drawing, air sampler of the present invention is described further.
Brief description of the drawings
Fig. 1 is the structural representation of air sampler of the present invention.
Embodiment
As shown in Figure 1, air sampler of the present invention comprises four gas circuit air sampler and expansion links, described expansion link is connected with the air inlet pipeline of described four gas circuit air samplers 6 by connecting link 5, the hollow circular cylinder that described expansion link is increased successively by three diameters is socketed to form, be followed successively by expansion link 1, middle expansion link 3 and lower expansion link 4, the bottom of described lower expansion link 4 is connected with described connecting link 5, described connecting link 5 is hollow circular cylinder, and the top of expansion link 1 is provided with at least one air admission hole 2 on described.
Preferably, described upper expansion link 1, middle expansion link 3 and lower expansion link 4 length are 0.3m, and wall thickness is 1cm; The diameter of described upper expansion link 1 is 10cm, and the diameter of middle draw-tube 3 is 12cm, and the diameter of upper expansion link is 10cm; Described air admission hole 2 is multiple, and each described air admission hole 2 arranges in the tube wall medium dip of upper expansion link 1; Described air admission hole 2 is 6; The diameter of described connecting link 5 is 14cm.
Above-described embodiment is described the preferred embodiment of the present invention; not scope of the present invention is limited; design under the prerequisite of spirit not departing from the present invention; various distortion and improvement that those of ordinary skill in the art make technical scheme of the present invention, all should fall in the definite protection domain of the claims in the present invention book.
