Description
Technical field
The utility model is related to construction environment noise measuring apparatus field, more particularly to a kind of multi-functional noise testing auxiliary
Device.
Background technology
Noise measuring is one of the indices detection project to construction site before construction, mostly uses all kinds of noise measurings
Instrument measures the size of decibel.Common detection mode is that artificial Handheld portable detector is walked about, or detector is fixed somewhere,
To measure the punishment shellfish size.
Currently, the Chinese patent of Publication No. CN206192494U discloses a kind of noise measuring instrument, it includes capacitance wheat
Gram wind and sound pick-up, further include shell, are equipped with turntable in shell rear surface, are connected with pedestal on the outside of turntable, the outer wall of pedestal is equipped with
Location hole.
This noise measuring instrument in use, is rotated by turntable, is driven the rotation of noise measuring instrument, is received each side
To noise.But due to can gradually weaken in sound wave transmittance process, therefore in actually measuring, far and near different survey at especially two
The noise intensity that amount point place measures, actual result are also easy to produce deviation.
Utility model content
The purpose of this utility model is to provide a kind of multi-functional noise testing auxiliary device, can be in measurement noise, more
Close to noise source so that the noise intensity measured is more acurrate.
The above-mentioned technical purpose of the utility model technical scheme is that：
A kind of multi-functional noise testing auxiliary device, including sound head, holding rod are surveyed, the survey sound head is fixed on holding rod
On, the holding rod is set as telescopic.

Source；If noise source is farther out, such as from ceiling, then stretches holding rod, then is directed toward the one end for surveying sound head is connected with
Noise source；If holding rod is contracted to compared with short status, can paste without stretching convenient for contact, holding rod by noise source
Nearly metope, and convenient for adjusting each switch surveyed on sound head manually, measure result.
Further setting：The holding rod includes at least two sections of mutually nested rod segments, and the rod segment side is equipped with aligning
Component, the aligning component are used to limit straight degree when rod segment movement.
By using above-mentioned technical proposal, rod segment, if only mutually being slid between rod segment, is be easy to cause in telescopic process
Radial direction between two neighboring rod segment or circumferential play.Aligning component defines rod segment radial direction during the motion or circumferential direction
Play so that the relative movement orbit between rod segment more levels off to straight line.
Further setting：The rod segment is divided into benchmark section, sliding section, and the aligning component includes aligning slot, the aligning
Slot is connected with benchmark section, and the sliding section is equipped with locating rod, and the locating rod penetrates in aligning slot.
By using above-mentioned technical proposal, movement benchmark of the benchmark section as sliding section, the relative position of benchmark section is constant,
It slides section during the motion, when the matching relationship between locating rod and aligning slot so that sliding section stretches out, is not easy between the two
Radial position deviation occurs.
Further setting：The aligning slot includes two symmetrically arranged rail bars, preset clearance between two rail bars, described fixed
Position bar is fallen in gap location.
By using above-mentioned technical proposal, when locating rod is fallen in gap, since two rail bars are symmetrical arranged, therefore locating rod pair
Tend to be equal in the active force of two rail bars, two rail bars are not easy to influence each other between each other.
Further setting：Side of the locating rod towards aligning slot is set as round end shape, and the gap inner wall is set as
Arc agrees with locating rod end shape.
By using above-mentioned technical proposal, fallen in locating rod when aligning in slot, in the round end structure of locating rod and gap
The mutual frictional force of the arcuate structure of wall, compared to the frictional force smaller of cube structure.
Further setting：The length of the aligning slot is equal to the length that holding rod is stretched to extreme position.
By using above-mentioned technical proposal, holding rod can be limited in telescopic process by aligning slot always.
Further setting：The axial length in the gap is less than the axial length of aligning slot, the diameter at the both ends in the gap
It is less than the radial dimension in gap centre position to size.
By using above-mentioned technical proposal, when slide section it is flexible when, move to extreme position, locating rod just by inlay card
It at the smaller szie of gap, is limited, is not easy to loosen.
Further setting：Aligning slot setting closed at both ends.
Extreme position is moved to when sliding section during exercise by using above-mentioned technical proposal, by aligning slot both ends
Limit, be not easy from aligning slot in go out.
In conclusion the utility model has the advantages that：
1, the length of holding rod can be adjusted according to practical the case where measuring place, close to noise source, to obtain more
Accurate measurement result；
2, during flexible holding rod, the relative displacement between rod segment is only limitted to axial displacement, makes between rod segment not
Catching phenomenon easily occurs.
