[0019] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0020] like Figure 1-3As shown, a refrigerator compressor noise detection tool comprises a box body 1, in which a first reed 131 and a second reed 14 are arranged, a predetermined gap is left between the first reed 131 and the second reed 14 to form a cavity 141, a detection rod 12 is arranged on the second reed 14, and the detection rod 12 is slidably arranged on a cover body 10 arranged on the box body 1, and a slide groove 11 is opened on the cover body 10.

[0021] Specifically, when in use, the box body 1 is buckled onto the compressor that needs to be tested, and then the compressor is started. The compressor makes a sound, and then the sound is transmitted to the first reed 131, and then the first reed 131 transmits the vibration to the second reed 14, transmitting the sound. At the same time, the second reed 14 pushes the detection rod 12 on its top upward and extends out on the cover body 10. Then, according to the extended length and the mark engraved by the detection rod 12, the decibel of the sound can be judged.

[0022] In the above scheme, the sound of the compressor is transmitted to the first reed 131 and the second reed 14 in the box body 1, and the vibration sound is transmitted to the detection rod 12 through the resonance of the first reed 131 and the second reed 14. The size of the sound is judged by observing the extension amplitude of the detection rod 12, thereby realizing the detection of the sound of the compressor through the vibration sound.

[0023] As an embodiment further provided by the present invention, according to Figure 1 , Figure 2 and Figure 3 As shown, a cavity 15 is formed on the box body 1, and a plurality of elastic members 171 arranged in a linear array are disposed in the cavity 15.

[0024] Furthermore, an inner shell 17 is disposed in the box body 1 , and there are two inner shells 17 . The inner shells 17 are provided with a plurality of silencer holes 16 arranged in a linear array.

[0025] Specifically, when the box body 1 is buckled on the compressor, external sound will be transmitted to the cavity 15 on the box body 1 through the silencer hole 16 on the inner shell 17, and then the inner shell 17 will vibrate, exerting force on the elastic member 171, which will be buffered by the elastic member 171.

[0026] As an embodiment further provided by the present invention, according to Figure 1 , Figure 2 and Figure 3 As shown, a sound insulation layer 161 is arranged between the two inner shells 17 .

[0027] Specifically, when the sound enters the cavity 15 through the silencer hole 16 , it enters the sound insulation layer 161 , and the sound is absorbed by the sound insulation layer 161 and then silenced.

[0028] As an embodiment further provided by the present invention, according to Figure 1 , Figure 2 and Figure 3 As shown, a fixing seat 18 is disposed at the bottom of the box body 1 , and a fixing block 13 is disposed at the bottom of the fixing seat 18 .

[0029] Specifically, the fixing seat 18 and the fixing block 13 fix the box body 1 on the compressor. It should be noted that the fixing block 13 is a suction cup, and the suction cup seals the connection between the box body 1 and the compressor.

[0030] Working principle: buckle the box body 1 onto the compressor that needs to be tested, and fix the box body 1 on the compressor through the fixing seat 18 and the fixing block 13. At the same time, when the box body 1 is buckled on the compressor, the external sound will be transmitted to the cavity 15 on the box body 1 through the silencer hole 16 on the inner shell 17, and then the inner shell 17 will vibrate, and will exert force on the elastic member 171, which will be buffered by the elastic member 171. Then start the compressor, the compressor will make a sound, and then it will transmit the sound to the first reed 131, and then the first reed 131 will transmit the vibration to the second reed 14, and transmit the sound. At the same time, the second reed 14 pushes the detection rod 12 on its top upwards and extends out on the cover 10. Then, according to the extended length and the mark engraved on the detection rod 12, the decibel of the sound can be judged.

[0031] The above only describes some exemplary embodiments of the present invention by way of illustration. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
