Embodiment
Shown in Fig. 1-4, the present invention is with limited block 2 respectively on the two ends of metal base plate 1, and slip cap was on metal base plate 1 in the middle of slide block 3 was positioned at two limited blocks 2; Be respectively equipped with four on slide block 3, the metal base plate 1 and gather hole 7, collection tube is passed collection hole 7 and is installed, and an end of slide block 3 is connected on the limited block 2 through limit spring 4; Four angles of metal base plate 1 are fixed on the Metallic rod of front-row seats headrest through a spring 5 respectively; Collection hole 7 through on 4 pairs of metal base plates 1 of limit spring, the slide block 3 provides clamping force; Realization utilizes spring 5 fixedly entire bracket stability and strong interference immunity to the installation of collection tube and fixing.
Limit spring 4 is three groups altogether, and each limit spring 4 is enclosed within on the limit spring support column 5, and an 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 passes 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 passes limited block pilot hole 10 its position is fixed.Four jiaos of metal base plate 1 are provided with location hole of the spring 11, make things convenient for the installation of spring 5 and fixing.Gathering base plate 1 is symmetrical mechanism.
Limit spring 4 slide block 3 when relaxed state staggers with the collection hole 7 of metal base plate 1 each other; Moving slider 3 makes that limit spring 4 was a compressive state when collection hole 7 of slide block 3 and metal base plate 1 overlapped.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, and the collection support is fixed on the 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 the 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 identical collection hole 7 of phase mutual edge distance, diameter is arranged all, when both overlap, can put into the air collection tube.What holding force is provided for collection tube is the limit spring 4 that is connected on slide block 3 and the limited block 2, limit spring 4 when relaxed state, the limited block 2 of slide block 3 deflection opposite sides; Staggering in 7 positions, collection hole of slide block 3 and metal base plate 1, makes both gather hole 7 when overlapping when firmly stirring slide block 3, and limit spring 4 is compressed; When inserting collection tube; Because the tension force of limit spring 4, slide block 3 moves to limited block 2, and collection tube is by collection hole 7 clampings of shearing each other.
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 compression spring.The length of limit spring support column 5 should guarantee slide block 3 when two end motions, and limit spring support column 5 can not break away from limit spring support column hole 9.
As shown in Figure 2, three limit spring support column pilot holes 8 are installed on the slide block 3, be used for fixing three limit spring support columns 6, three limit spring support column holes 9 are arranged on limited block 2, be used for doing location and guiding function.Earlier limit spring 4 is packed on the limit spring support column 6 in the time of installation, then on the limit spring support column hole 9 that limit spring support column 6 is inserted on the limited blocks 2.All there is limited block pilot hole 10 both sides of limited block 2, use bolt to be fixed.
When using the present invention to carry out sample collecting, at first, front-seat main the driving with copilot station of automobile suitably aligned (backrest and horizontal line meet at right angles approximately), then the main driving in front row and assistant driver seat being rested the head on transfers to the highlyest, and locks.Secondly, buckle respectively on main driving and the Metallic rod of copilot near the inboard gathering support left and right sides spring 5, suitably the adjustment height makes the collection backing positions approximately be positioned at passenger's breathing zone height and maintenance level, and gather the plane, hole perpendicular to surface level this moment.At this moment, slide block 3 is stirred to limited block 2 directions, made inside and outside 7 holes of gathering keep alignment, four air collection tubes are inserted gather about the about 2cm in hole, unclamp slide block 3, then the air collection tube is locked.This air harvester is convenient, fast, and all operations all need be by instrument, and structure keeps stable in the gatherer process, and height and width-adjustable, is particularly suitable for air sample collection in the car.
The present invention will gather support through the spring 5 of symmetry and be connected with the headrest Metallic rod, reach comparatively stable effect, with respect to bolt, have characteristics such as quick, convenient.Owing to use the spring 5 of symmetry, make the expanded range of acquisition target not to be only applicable to narrower car, also be suitable for the commercial vehicle of vehicle body broad etc.And four conduits of clamping easily also keep the stability of gatherer process, guarantee to gather the air sample data validity.
Combine accompanying drawing that the present invention has been carried out exemplary description above; Obviously the concrete realization of the present invention does not receive the restriction of aforesaid way; As long as the various improvement of having adopted technical scheme of the present invention to carry out, or directly apply to other occasion without improvement, all within protection scope of the present invention.
