Description
Technical field
The utility model relates to silencing means technical fields, and in particular to a kind of sound attenuator.
Background technique
Insulation monitoring device needs to test before factory, when examining, if insulation monitoring device is unqualified, from
The buzzer of band can pipe.In order to monitor piping for buzzer, under normal circumstances, the test site of insulation monitoring device is more
In quiet small room, decibel value when due to buzzer call can reach 70~75dB, be more than that human ear is acceptable comfortable
The maximum decibel upper limit of degree, the testing crew for being chronically at test bay can feel irritated, feel bad, be chronically at this environment feelings
Nerve can be damaged under condition, influence the health of testing crew.
Utility model content
The purpose of this utility model is to provide a kind of sound attenuators, to solve the noise decibel mistake that existing product test generates
Height influences the problem of the health of testing crew.
The technical solution that the utility model solves above-mentioned technical problem is as follows:
A kind of sound attenuator, comprising: sound attenuator ontology and be placed in the intrinsic suspension apparatus of sound attenuator；Sound attenuator ontology packet
Noise reduction layer is equipped on the inside of the case lid for including cabinet and connecting with cabinet, cabinet and case lid, noise reduction layer is equipped with multiple sound-absorbings
Wedge；The side wall of cabinet is equipped with the wire guide through noise reduction layer；Suspension apparatus includes parcel shelf and lifting rope, and parcel shelf is by hanging
Rope is suspended in the inside of cabinet.
The utility model sound attenuator ontology can the test products such as housing insulation monitoring device, the setting of sound attenuator body interior
Noise reduction layer can reduce the devices such as buzzer sending sound decibel value.Multiple sound absorption wedges can be made inside sound attenuator
With regard to a free found field without reflected sound and back drop, prevent buzzer etc. from being formed back inside sound attenuator when making a sound
Sound avoids sound from being superimposed, to avoid the occurrence of the decibel value of sound of outflow sound attenuator the case where cannot being effectively reduced or appearance
Not the phenomenon that not dropping anti-increasing.Parcel shelf is soft by lifting rope and sound attenuator ontology for placing the test products such as insulation monitoring device
Property connection.When test products make a sound, parcel shelf vibration will drive, due to the effect of flexible connection, the vibration of parcel shelf is not
It can be transmitted on sound attenuator, so as to avoid keeping sound attenuator appearance miscellaneous due to the rigid connection between parcel shelf and sound attenuator
Sound, so that the sound for avoiding buzzer from issuing is interfered by noise.Communication line and power supply line of test products etc. can be from leading
It is pierced by string holes, and is connect with the external world.Due to needing judge whether product is qualified by piping for buzzer during test,
It does not need to carry out zero acoustic isolation by sound attenuator, need to only reduce the decibel value for being pierced by sound from sound attenuator.
Further, decibel detector and the outer decibel detector of case in case are respectively equipped on above-mentioned case lid.
Decibel detector can detecte the sound decibel value in case, and real-time display in the case of the utility model, prevent from trying
The personnel of testing miss piping for buzzer and cause misjudgment, to avoid the appearance of substandard product.In addition, outflow sound attenuator
Sound reduce after, if laboratory's noise is larger, testing crew is not easy to tell the sound of sound attenuator outflow, can lead at this time
It crosses decibel detector in case and may determine that whether buzzer has been sent from and pipe.The outer decibel detector of case can detecte in laboratory
Sound decibel value, by the value that decibel detector is shown outside case, thus by the sound control of laboratory in suitable range.
Further, the model of decibel detector and the outer decibel detector of case is WS900A in above-mentioned case.
Further, above-mentioned cabinet is tightly connected by sealing strip and case lid.
Cabinet and case lid are sealed, can be effectively reduced from cabinet and case lid when case lid is closed by the utility model
Sealing at the decibel value that makes a sound.
Further, the side hinge of the side of above-mentioned cabinet and case lid connects.
The cabinet of the utility model is connected by a hinge with case lid, the efficiency of switch case lid can be improved, to improve examination
Test efficiency.
Further, trapezoidal shape of above-mentioned sound absorption wedge.
Further, the material of above-mentioned noise reduction layer is silencing cotton.
The utility model has the following beneficial effects:
1, the utility model is divided by sound attenuator by the sound being pierced by inside the noise reduction layer place of can be effectively reduced sound attenuator
Shellfish value, the parcel shelf inside sound attenuator, which is carried out the sound absorption wedge inside suspention and sound attenuator, can prevent the appearance of noise.
2, decibel instrument can prevent testing crew from missing piping for buzzer in case with the decibel value of sound in real-time display case
And cause misjudgment or laboratory's noise is larger and testing crew cannot accurately be judged.
