Embodiment
In order to better understand the utility model, illustrate below in conjunction with drawings and Examples.
Embodiment one: as shown in Figure 1, a kind of sampling head locking device, comprise sampling thief joint 1, sampling thief holder 2 and clamping device 3, sampling thief joint 1 outer wall is provided with clamping device 3, be distributed in a pair clamping device acting in conjunction at sampling thief bond diameter two ends.Described clamping device 3 comprises handle 31, pull bar 32 and handle set 33, is flexibly connected bottom handle 31 by Handle axis 34 with handle set 33, and described pull bar 32 is connected on handle 31 by pull rod shaft 35; Described sampling thief holder 2 is provided with the grab 22 matched with pull bar 32.
Described sampling thief holder 2 upper end comprises ring cap body 21, and described cap body 21 edge is provided with radially inside breach, forms described grab 22 between two breach, and grab 22 diametrically tangent plane is L-type, can tangle the bend of described U-shaped pull bar 32.Grab 22 and sampling thief holder 2 are integral type structure, and the basis of holder cap body 21 processes, and this structural rate external screw-thread coupling hook is more firm, and the pulling force that can bear is large, and not fragile.
In order to better clamping device 3 is fixed on sampling thief joint 1, described sampling thief joint 1 outer wall is provided with the pickup groove 11 of mounting handle seat, the fixed orifice 12 corresponding with described handle set screw 36 is provided with in described pickup groove 11, screw 36 on described handle set 33 is four, is distributed in the corner of handle set 33.
In order to make handle 31 do not polluted by spot on hand and increase feel, the handgrip part of described handle 31 also overlaps and has rubber protecting jacket.
During installation, the handle set 33 of clamping device 3 is put in pickup groove 11, and fixes with screw.Sampling thief joint 1 is inserted in sampling thief holder 2, U-shaped pull bar 32 is hung over grab 22 li, handle 31 is broken by below and can realize fixedly securing of sampling thief to top, convenient and swift.
Embodiment two: as in Figure 2-4, a kind of single channel particle collection device, comprise sampling thief 4, sampling thief joint 1, sampling thief holder 2 and main frame 5, described sampling thief joint 1 outer wall is provided with clamping device 3, described clamping device 3 comprises handle 31, pull bar 32 and handle set 33, pull bar 32 is U-shaped, is flexibly connected bottom handle 31 by Handle axis 34 with handle set 33, and described pull bar 32 is connected on handle 31 by pull rod shaft 35; Sampling thief holder 2 upper end comprises ring cap body 21, and described cap body 21 edge is provided with radially inside breach, forms described grab 22 between two breach, and grab 22 diametrically tangent plane is L-type, can tangle the bend of described U-shaped pull bar 32.
Need to use PM
2.5when cutter 6 is sampled, by PM
