Description

Technical Field

[0001] This utility model relates to the field of environmental acoustic testing technology, and in particular to an acoustic vibration analysis device. Background Technology

[0002] Acoustic vibration analysis devices are a class of equipment used to detect, analyze, and evaluate the characteristics of sound waves and vibrations. They are widely used in noise control, mechanical diagnostics, and structural monitoring. They collect sound wave or vibration signals through sensors and analyze parameters such as frequency, amplitude, and phase to determine the health status of equipment or structures. Common acoustic vibration analysis devices include accelerometers, sound level meters (decibels), and vibration analyzers. Decibels, as one type, are mainly used to measure sound pressure levels and quantify noise intensity, and are one of the important tools in acoustic vibration analysis, helping to assess the acoustic performance of the environment and equipment.

[0003] In existing technologies, the decibel head of most decibel meters is directly fixed to the head of the decibel meter housing. The decibel head, which contains a large number of precision sensors, is easily damaged by external impacts, affecting measurement accuracy or causing equipment failure. The decibel head cannot be flexibly stored, and users need to be especially careful when storing and carrying it, which increases the difficulty of protecting the equipment and the inconvenience of use. Summary of the Invention

[0004] The purpose of this invention is to address the problems in the existing technology where the decibel head of most decibel meters is directly fixed to the head of the decibel meter housing. The decibel head, which contains a large number of precision sensors, is easily damaged by external impacts, affecting measurement accuracy or causing equipment failure. Furthermore, the decibel head cannot be flexibly stored, requiring users to be particularly careful when storing and carrying it, which increases the difficulty of equipment protection and inconvenience in use. Therefore, this invention proposes an acoustic vibration analysis device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] An acoustic vibration analysis device includes a top cover box, a bottom cover box, and a decibel head. A control panel is fixedly installed inside the bottom cover box, and an input panel is installed on the top of the top cover box. The control line of the input panel is connected to the control panel. The bottom cover box is fixedly installed on the top cover box with bolts. A top groove is opened on the side of the top cover box, and a bottom groove is opened below the top groove of the bottom cover box. A central cylinder is opened on the top of the top cover box, and a decibel head is fixedly installed on the side of the central cylinder. A storage component is provided near the central cylinder of the top cover box to control the decibel head to be stored inside the top cover box or to extend out of the inner cavity of the top cover box.

[0007] Optionally, the storage assembly includes a locking nut and an anti-detachment component, and the top cover box has a C-shaped groove on the side of the central cylinder.

[0008] Optionally, the head of the locking nut is corrugated, the width of the head of the locking nut is greater than the width of the C-groove, and the tail of the locking nut is threaded into the decibel head.

[0009] Optionally, the anti-detachment component includes a horizontal L-bar, a C-ring, and a vertical bolt, wherein the horizontal L-bar includes a vertical section and a horizontal section.

[0010] Optionally, one end of the horizontal section of the horizontal L-bar is fixedly installed on the side of the C-ring, and the vertical section of the horizontal L-bar is fixedly connected to the top of the top cover box using vertical bolts.

[0011] Optionally, the C-ring is suspended above the C-groove, and the top-view projection size of the C-ring is equal to the top-view projection size of the C-groove.

[0012] Compared with the prior art, the present invention has the following advantages:

[0013] 1. The main structure of this utility model includes a top cover box, a bottom cover box, and a decibel head. The decibel head is rotatably mounted on the top cover box, and a storage component is provided on the top of the top cover box. The storage component can control the decibel head to extend or retract from the inner cavity of the top cover box. When the entire decibel meter is in standby mode, it can effectively protect the decibel head. This avoids the problems of existing decibel meters where the decibel head is mostly directly fixed to the head of the decibel meter housing. The decibel head, which contains a large number of precision sensors, is easily damaged by external impacts, affecting the measurement accuracy or causing equipment failure. The decibel head cannot be flexibly stored, and users need to be especially careful when storing and carrying it, which increases the difficulty of equipment protection and the inconvenience of use.

[0014] 2. This utility model has an anti-detachment component on the top of the top cover box. The anti-detachment component can prevent the locking nut, one of the core components of the storage component, from being over-screwed out, which would cause the locking nut to be lost.

A decibel head 8 is fixedly installed on the side of the vertical cylinder 7. A wire hole 6 is provided on the side of the vertical cylinder 7 for the wires of the sensor inside the decibel head 8 to pass through.

[0022] The top cover box 3 is provided with a storage component near the central cylinder 2, which can be used to store the decibel head 8 inside the top cover box 3 or extend from the inner cavity of the top cover box 3. The storage component includes a locking nut 1 and an anti-detachment component. The top cover box 3 has a C-shaped groove 31 on the side of the central cylinder 2. The head of the locking nut 1 is corrugated and the width of the head of the locking nut 1 is greater than the width of the C-shaped groove 31. The tail of the locking nut 1 is screwed into the decibel head 8.

[0026] In its initial state, the decibel head 8 is housed inside the cavity formed by the top cover box 3 and the bottom cover box 4. When the decibel head 8 is needed, the locking nut 1 is loosened manually. By moving the locking nut 1 along the C-shaped groove 31, the decibel head 8 is rotated to a state parallel to the top cover box 3. Finally, the locking nut 1 is tightened again, and the decibel head 8 is fixed by the friction between the head of the locking nut 1 and the top surface of the top cover box 3.
