Description
Technical field
The utility model belongs to air sampling technical field, and in particular to a kind of buffer of impact sampler.
Background technology
In air sampling field, conventional is a kind of impacting type sampling, and air extractor connects with the gas outlet of ram,
Air enters ram from the air inlet of ram, is arranged at every grade of sampling ware classification collection sampled targets hit after disk.Cause
Need to avoid, so the mounting structure of sampling ware is very simple, to be not provided with by air pollution in installation process for sampling ware
Locking mechanism, therefore during sampling, the stability of ram in itself influences whether the effect of sampling.
In the prior art, ram is fixed generally by tripod.Connection between tripod and buffer
Mode is usually single-point connection or plane connection, it is difficult to is completely counterbalanced by the vibrations of air extractor or airflow counter-collision in sampling process
Hit the influence of the stability of device sampling ware.
The content of the invention
Technical problem to be solved in the utility model is to provide a kind of the slow of big flow ram for air sampling
Device is rushed, reaches the effect of the stability of ram in increase sampling process.
In order to solve the above-mentioned technical problem, the utility model is achieved through the following technical solutions：One kind is used for air
The buffer of the big flow ram of sampling, includes housing, half end cap, inner tray, circle ball and spring, and the housing is rotation
Turn part, the top of housing is provided with cushion chamber, and the diameter of lower housing portion is less than top and external threading, half end cap, inside
Pallet, circle ball and spring may be contained within the cushion chamber of housing, and the inner tray is arranged at the bottom in cavity, the spring
It is arranged between inner tray and buffering bottom of chamber face and is connected respectively with both, half end cap is arranged at the top in cavity,
Be interference fit between half end cap and cavity, the ball is arranged between inner tray and half end cap, half end cap it is upper
End is provided with opening, exposes from half end cap upper end open the rounded portion.
Further, half cover internal is provided with the part-spherical cavity being engaged with ball, the upper table of the inner tray
Face central area is provided with a concave surface being engaged with ball.
Further, the cavity wall of half end cap extends downward into the bottom of cushion chamber, and the external diameter of the inner tray is little
In the internal diameter of half end cap.
Further, the spring is fixed on the bottom surface of cushion chamber by glue.
The present invention is advantageous in that after buffer is installed on into the big flow ram for air sampling, can increase
Add the stability of ram in sampling process, the sampling ware for avoiding not having locking device inside ram occurs in sampling process
Rock, ensure sample effect.
Brief description of the drawings
The utility model is further illustrated below in conjunction with the accompanying drawings.
Fig. 1 is stereogram of the present utility model；
Fig. 2 is sectional view of the present utility model；
Fig. 3 is explosive view of the present utility model.
In figure：1st, housing；2nd, half end cap；3rd, inner tray；4th, ball；5th, spring；6th, cushion chamber.
Embodiment
Below in conjunction with the accompanying drawings and the utility model is described in detail embodiment：
As shown in figure 3, the present apparatus includes housing 1, half end cap 2, inner tray 3, ball 4 and spring 5, housing 1 is rotation
Part, the top of housing 1 are provided with cushion chamber 6.
As shown in Fig. 2 the diameter of the bottom of housing 1 is less than top and is externally threaded, half end cap 2, inner tray 3, circle
Ball 4 and spring 5 are all installed in the cushion chamber 6 on the top of housing 1.Spring 5 is bonded at by glue on the bottom surface of cushion chamber 6, internal
Pallet 3 is arranged on the bottom of cushion chamber 6 and contacted with spring 5.With reference to Fig. 3 as can be seen that the upper face center portion of inner tray 3
Set up the concave surface for being equipped with and being engaged with ball 4 separately.Half end cap 2 is fixedly installed in the top of cushion chamber 6 and was between cushion chamber 6
It is full of cooperation, the cavity wall of half end cap 2 extends downward into the bottom of cushion chamber 6, and the internal diameter of half end cap 2 is outer not less than inner tray 3
Footpath.With reference to Fig. 3 as can be seen that half end cap 2 is provided with the cavity of a part-spherical.Ball 4 is arranged at half end cap 2 and internal support
Between disk 3, and can be therebetween space in move freely through.The top of half end cap 2 is provided with opening, and ball 4 is partly
Expose from the opening.
After present apparatus installation as shown in Figure 1.
During installation, buffer is installed on the end cap of ram by the screw thread attaching nut of the bottom of housing 1, buffer
Ball 4 be in contact with ram fixing device.
In sampling process, when due to air extractor, flow perturbation or other reasonses cause ram to shake when, buffering
The ball 4 of device further contacts with ram fixing device, and ball 4 oppresses inner tray 3 to moving inside cushion chamber 6, internal
Pallet 3 moves under the pressure of ball 4 to the bottom of cushion chamber 6, pressuring spring 5.Impulsive force is stored as elastic potential energy by spring 5,
So as to reduce ram shaking amplitude, stability of the increase ram in sampling process.
The ball 4 of buffer can also be freely rotatable in the space between half end cap 2 and inner tray 3, be received outer
The masterpiece used time can more gently rotate in ram fixing device, increase the stability of ram.
It is emphasized that：It the above is only preferred embodiment of the present utility model, not the utility model appointed
What formal limitation, every any simple modification made according to the technical essence of the utility model to above example, etc.
With change and modification, in the range of still falling within technical solutions of the utility model.
