Description

Technical Field

[0001] The utility model relates to the technical field of noise spectrum analyzers, in particular to a portable noise spectrum analyzer. Background Art

[0002] A noise spectrum analyzer is an instrument used to measure the spectral characteristics of noise signals. It can analyze complex noise signals in the frequency domain, providing engineers and researchers with important information about the source and characteristics of noise. Through the noise spectrum analyzer, users can obtain parameters such as the frequency component, amplitude distribution, and harmonic content of noise signals, so as to better understand and process noise signals. A noise spectrum analyzer usually includes an input signal interface, a spectrum analysis module, and a data display and storage module. Users can import the noise signal to be measured into the analyzer through the input signal interface, and then use the spectrum analysis module to perform spectrum analysis on the signal, and finally view and record the analysis results through the data display and storage module.

[0003] However, the existing instrument has the following problems: the display screen and control buttons of the instrument are exposed to the outside, which can easily cause scratches on the display screen during use, affecting the observation of data, and it is also easy to accidentally touch the buttons, resulting in inaccurate data from the instrument. Utility Model Content

[0004] The utility model aims to solve the shortcomings of the prior art that the display screen and control buttons of the instrument are exposed, which may easily cause scratches on the display screen during use, affecting the observation of data, and may also easily touch the buttons by mistake, resulting in inaccurate data of the instrument, and thus proposes a portable noise spectrum analyzer.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A portable noise spectrum analyzer comprises an instrument body, a display screen for displaying detection data is arranged on the top of the instrument body, a control button for controlling the instrument body is arranged on the top of the instrument body, a connection hole for connecting with a connection line is arranged on the outside of the instrument body, and a detection end is arranged on one side of the instrument body;

[0007] A shielding mechanism is arranged on the top of the instrument body to protect the display screen and control buttons.

[0008] In a possible design, the shielding mechanism includes a shielding frame, a shielding plate and a pushing plate. The bottom of the shielding frame is fixedly connected to the top of the instrument body. The shape of the shielding frame is set to be U-shaped. Slide grooves are provided on the inner walls on both sides of the shielding frame. The two sides of the shielding plate are respectively slidably connected to the two slide grooves. The top side of the shielding plate is fixedly connected to the bottom of the pushing plate. The height of the pushing plate is greater than the height of the shielding frame.

[0009] In a possible design, the rear side of the push plate is fixedly connected with an elastic rope for fixing the shielding plate, the top of the instrument body is fixedly connected with a fixing column, the fixing column is located on the rear side of the shielding frame, the height of the fixing column is greater than the height of the shielding frame, the elastic rope is looped on the fixing column, and the top of the fixing column is fixedly connected with a limit block for preventing the elastic rope from slipping.

[0010] In a possible design, two elastic bands are fixedly connected to the bottom of the instrument body for easy carrying.

[0011] In a possible design, a placement groove is provided at the bottom of the instrument body for facilitating the placement of the shielding plate.

[0012] In a possible design, a connecting ring is fixedly connected to the outer side of the instrument body for facilitating the placement of the instrument body.

[0013] In the present application, during use, detection is performed through the detection end, and the instrument body is controlled through the control button, and the detection data is displayed and recorded through the display screen. When the instrument body is used, the top of the instrument body is blocked by sliding the sliding grooves on the shielding plate and the shielding frame to protect the display screen and the control buttons, reduce damage to both, and thus extend the service life of the instrument body. After the shielding plate is moved by the push plate, the elastic rope on the shielding plate is set on the fixed column, and the shielding plate is fixed by the elasticity of the limit block and the elastic rope to prevent the shielding plate from falling off the shielding frame, so as to maintain the protection of the display screen and the control buttons. Then, the instrument body is carried by putting the elastic band on an object or an arm, which is convenient for holding and moving the instrument body, thereby improving the practicality and flexibility of the instrument body. When the instrument body needs to be placed, the instrument body can be hung by the connecting ring, thereby facilitating the reduction of the erosion of the instrument body by flat water stains. When the instrument body is in use, the shielding plate can be placed in the placement slot to prevent the shielding plate from being lost.

[0014] The beneficial effects of the utility model are:

[0015] In the utility model, the shielding mechanism and the elastic band arranged at the bottom facilitate shielding the top of the instrument body, thereby protecting the display screen and the control buttons, reducing damage to both, and extending the service life of the instrument body. At the same time, the elastic band is sleeved on an object or an arm to carry the instrument body, making it convenient to hold and move the instrument body, thereby improving the practicality and flexibility of the instrument body.

[0024] A display screen is provided on the top of the instrument body 1 for displaying the detection data. At the same time, a control button is also provided on the top to facilitate the user to control the instrument body 1. A connection hole is provided on the outside of the instrument body 1 for connecting with a connecting line, and a detection end is provided on one side of the instrument body 1 for noise detection.

[0025] In order to protect the display screen and control buttons, a shielding mechanism is specially provided, which includes a shielding frame 2, a shielding plate 3 and a pushing plate 5. The bottom of the shielding frame 2 is fixedly connected to the top of the instrument body 1 and is U-shaped. Its inner walls on both sides are provided with sliding grooves, and the two sides of the shielding plate 3 are respectively slidably connected to the two sliding grooves, so that the shielding plate 3 can slide in the shielding frame 2, and one side of the top of the shielding plate 3 is fixedly connected to the bottom of the pushing plate 5. The height of the pushing plate 5 is greater than the height of the shielding frame 2, so that the user can conveniently operate the shielding plate 3 through the pushing plate 5.

[0026] In order to enhance the stability of the shielding plate 3, we fixedly connected an elastic rope 8 to the rear side of the pushing plate 5, and also fixedly connected a fixing column 9 to the top of the instrument body 1, which is located on the rear side of the shielding frame 2 and has a height greater than that of the shielding frame 2. The elastic rope 8 is sleeved on the fixing column 9. When the shielding plate 3 slides to the bottom of the shielding frame 2, the elastic rope 8 will be tightened, thereby fixing the shielding plate 3. A limit block 10 is also fixedly connected to the top of the fixing column 9 to prevent the elastic rope 8 from slipping.
