Detailed description of the invention
Fig. 1 is the schematic perspective view of the noise dose meter auxiliary stand of one embodiment；
Fig. 2 is the noise dose meter auxiliary stand of one embodiment and the stereochemical structure signal that noise dose meter is used cooperatively
Figure.
Specific embodiment
The principles of the present invention and feature are described below in conjunction with attached drawing, example is served only for explaining that this is practical
It is novel, it is not intended to limit the scope of the utility model.
In one embodiment, as shown in Figure 1, a kind of noise dose meter auxiliary stand, including fixing piece 100, load-bearing part
200, elastic component 300, telescopic rod 400 and pedestal 500.The load-bearing part 200 offers placing groove 201, the placing groove 201
Side wall is provided with first buffer layer 202；One end of the elastic component 300 is connect with the fixing piece 100, the elastic component 300
The other end connect with the outer surface of the load-bearing part 200；One end of the telescopic rod 400 deviates from the fixing piece 100
The one side of the elastic component 300 connects；The pedestal 500 connects with the telescopic rod 400 far from one end of the fixing piece 100
It connects, the pedestal 500 is provided with second buffer layer 501 away from the telescopic rod on one side.
Noise dose meter auxiliary stand in above-described embodiment is achieved in that, referring to Fig. 2, noise dose meter 800
It is placed in placing groove 201, when the vibration on ground is transferred to pedestal 500, first passes around second buffer layer 501, second buffering
Layer 501 plays buffer function, part vibration is absorbed, to enable the top of noise dose meter auxiliary stand more stable, immediately
Vibration when being transferred to elastic component 300, part vibration energy is converted into the elastic potential energy of elastic component 300, and elastic potential energy release needs
Energy can be lost when wanting certain time, and converting, to play buffer function, and elastic component 300 can also make under vibration frequency
Drop enables vibration be transformed into shaking, and the measurement influence shaken on noise dose meter is smaller than the influence of vibration, finally, second buffer layer
501 again serve to buffer function, further decrease the influence shaken to noise dose meter, and telescopic rod 400 is for adjusting noise
The whole height of dosimeter auxiliary stand guarantees to be tested in desired test height.
To make the height convenient for learning noise dose meter auxiliary stand, in one embodiment, as shown in Fig. 2, described
Scale is provided on telescopic rod 400.The height of noise dose meter auxiliary stand entirety can be converted by the height of telescopic rod 400
Degree, it follows that the height of noise dose meter auxiliary stand, specifically, the scale are used to observe the length of telescopic rod 400, and
The length of noise dose meter auxiliary stand is equal to 400 length of telescopic rod and adds a fixed number, which is pedestal 500, admittedly
Determine the sum of part 100, elastic component 300 and height of load-bearing part 200.
Elastic component 300 is for buffering, so that vibration weakens or vibration is made to be converted into shaking, for example, the elastic component 300
For spring.In another example the elastic component 300 is pressure spring.For another example the elastic component 300 is elastic slice.
For elastic component 300 is better distributed the effect of power to load-bearing part 200, so that load-bearing part 200 is more steady
Fixed, in one embodiment, the quantity of the elastic component 300 is multiple.Multiple elastic components 300 are uniformly arranged on described hold
Holder 200 deviates from the one side of the placing groove 201.
To place noise dose meter, in one embodiment, as shown in Figure 1, the bottom of the placing groove 201 has one to hold
Section 203, the loading end 203 are gradually obliquely installed to 500 direction of pedestal from one end to the other end.Specifically, the carrying
Face 203 is arranged close to one end protrusion of pedestal 500 by limited block 204.Specifically, the surface of the load-bearing part 200 is provided with bullet
Property bandage 600, the placing groove 201 has a notch 205, and the elastic bands 600 are set on the notch 205.Thus
When noise dose meter is placed in placing groove 201, and the bottom of noise dose meter is connected to the limited block 204, elastic bands
600 are connected to the surface of noise dose meter, play the role of steady noise dosimeter.
To realize pooling feature, so that the 501 pairs of vibrations of first buffer layer 202 and second buffer layer buffer, shake is reduced
The dynamic influence to noise dose meter, for example, the first buffer layer 202 is rubber layer.In another example the first buffer layer is cotton
Flower layer, for another example, the first buffer layer are foamed layers.For example, the second buffer layer 501 is rubber layer.For example, described
Second buffer layer 501 is plastic layer, and specifically, the second buffer layer is that (PVC, Polyvinyl chloride gather layer of PVC
Vinyl chloride).For another example, the second buffer layer is TPU layer (TPU, Thermoplastic Urethane, polyurethane).Described
Two buffer layers need to take into account wear problem while taking into account damping, and layer of PVC or TPU layer are plastic layer, and plastics have certain
Elasticity, cushioning effect can be played, meanwhile, plastic layer is more wear-resisting than rubber layer, enable plastic layer to take into account wear problem, extend
Second buffer layer service life.
The above is only the preferred embodiment of the present invention, is not intended to limit the utility model, all practical at this
Within novel spirit and principle, any modification, equivalent replacement, improvement and so on should be included in the guarantor of the utility model
Within the scope of shield.
