Embodiment
As Figure 1-4, the present invention overlaps respectively limited location piece 2 on the two ends of metal base plate 1, slide block 3 be positioned at two limited blocks 2 in the middle of slip caps on metal base plate 1; On slide block 3, metal base plate 1, be respectively equipped with four and gather hole 7, collection tube is installed through gathering hole 7, and one end of slide block 3 is connected on limited block 2 by limit spring 4; Four angles of metal base plate 1 are fixed in the Metallic rod of headrest for front row seat by a spring 5 respectively, provide clamping force by limit spring 4 to the collection hole 7 on metal base plate 1, slide block 3, realize the installation to collection tube and fix, utilizing spring 5 to be fixed whole support stability and strong interference immunity.
Limit spring 4 is three groups altogether, and each limit spring 4 is enclosed within on limit spring support column 5, and one end of limit spring support column 5 is fixed on the limit spring support column pilot hole 8 of slide block 3, and the other end is through the limit spring support column hole 9 of corresponding limited block 2.
The both sides of limited block 2 are provided with limited block pilot hole 10, and bolt is fixed its position through limited block pilot hole 10.Four jiaos of metal base plate 1 are provided with location hole of the spring 11, facilitate the installation of spring 5 and fix.Gathering base plate 1 is symmetrical mechanism.
Limit spring 4 slide block 3 in the time of relaxed state staggers mutually with the collection hole 7 of metal base plate 1; When moving slider 3 makes slide block 3 overlap with the collection hole 7 of metal base plate 1, limit spring 4 is compressive state.The internal diameter of limit spring 4 is greater than the internal diameter in limit spring support column hole 9.
The present invention utilizes the elastic force of spring to provide support and tensile force, makes to gather support and is fixed in chair headrest Metallic rod.Mainly comprise metal base plate 1, slide block 3 and 2 three parts of limited block.Wherein two limited blocks 2, slide blocks 3 are connected on metal base plate 1 successively, and slide block 3 can slide between two limited blocks 2.On slide block 3 and metal base plate 1, all there are all identical collection holes 7 of phase mutual edge distance, diameter, in the time that both overlap, can put into air acquisition conduit.What provide holding force for collection tube is the limit spring 4 being connected on slide block 3 and limited block 2, limit spring 4 is in the time of relaxed state, slide block 3 is partial to the limited block 2 of opposite side, stagger in 7 positions, collection hole of slide block 3 and metal base plate 1, in the time firmly stirring slide block 3 and make both gather hole 7 and overlap, limit spring 4 is compressed, while inserting collection tube, due to the tension force of limit spring 4, slide block 3 moves to limited block 2, collection hole 7 clampings that collection tube is sheared mutually.
Spring 5 adopts extension spring, and spring 5 length are about 10cm.The internal diameter of limit spring 4 should be slightly larger than the internal diameter in limit spring support column hole 9, and adopts Compress Spring.The length of limit spring support column 5 should ensure that slide block 3 is in the time of two end motions, and limit spring support column 5 can not depart from limit spring support column hole 9.
As shown in Figure 2, three limit spring support column pilot holes 8 are installed on slide block 3, are used for fixing three limit spring support columns 6, on limited block 2, have three limit spring support column holes 9, be used for locating and guiding function.When installation, first limit spring 4 is packed on limit spring support column 6, then on the limit spring support column hole 9 of limit spring support column 6 being inserted on limited block 2.The both sides equal limited location piece pilot hole 10 of limited block 2, uses bolt to be fixed.
Using the present invention while carrying out sample collection, first, front-seat automobile main driving and copilot station suitably be aligned to (backrest and horizontal line approximately meet at right angles), then front-seat main driving and assistant driver seat headrest are adjusted to the highlyest, and lock.Secondly, buckle respectively in main driving and copilot in the Metallic rod near inner side gathering support left and right spring 5, suitably adjust height, make to gather backing positions and be approximately positioned at passenger's breathing zone height and keep level, now gather hole plane perpendicular to surface level.Now, slide block 3 is stirred to limited block 2 directions, made inside and outside 7 holes that gather keep alignment, four air acquisition pipes are inserted and gather about 2cm left and right, hole, unclamp slide block 3, air acquisition pipe is locked.This air acquisition device is convenient, fast, and all operations all need to be by instrument, and in gatherer process, structure keeps stable, and height and width adjustable, be particularly suitable for the interior air sample collection of car.
The present invention will gather support by symmetrical spring 5 and be connected with headrest Metallic rod, reach comparatively stable effect, fix with respect to bolt, have the features such as quick, convenient.Owing to using symmetrical spring 5, make the expanded range of acquisition target, be not only applicable to narrower car, be also suitable for the wider commercial vehicle of vehicle body etc.And can clamp easily four conduits and keep the stability of gatherer process, ensure to gather air sample data validity.
By reference to the accompanying drawings the present invention is exemplarily described above; obviously specific implementation of the present invention is not subject to the restrictions described above; as long as the various improvement that adopted technical solution of the present invention to carry out, or directly apply to other occasion without improvement, all within protection scope of the present invention.
