[0046] The following will be combined with the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0047] like Figure 1 to Figure 4 As shown, the utility model proposes a portable noise analyzer, including a noise analyzer body 1, and also includes an analyzer holding component, a placement box 2, a hanging mechanism, a hanging belt 3, a temporary sampling mechanism and a mounting tube 4. The analyzer holding component is installed on the noise analyzer body 1, the noise analyzer body 1 is in contact with the placement box 2, the hanging mechanism is installed on the placement box 2, the hanging belt 3 is fixedly connected to the placement box 2, the temporary sampling mechanism is installed on the top of the placement box 2, and the mounting tube 4 is detachably connected to the placement box 2. The analyzer holding component and the hanging mechanism cooperate. When it is inconvenient for workers to hold the noise analyzer body 1, the noise analyzer body 1 can be placed on the placement box 2 and tied around the waist, which is convenient for taking and using at any time, and at the same time prevents the noise analyzer from falling to the ground and being damaged. The temporary sampling mechanism plays a role in that when it is inconvenient for workers to use the noise analyzer body 1, the noise analyzer body 1 is installed on the placement box 2, which is convenient for noise analysis in various environments and improves the applicability of the portable noise analyzer.

[0048] Among them, the analyzer holding assembly includes a mounting ring 5, an elastic rope 6 and a disassembly rod 7. There are two mounting rings 5, one of which is fixedly connected to the noise analyzer body 1, and the other is fixedly connected to the placement box 2. The elastic rope 6 is fixedly connected between the two mounting rings 5. The disassembly rod 7 is fixedly connected to the bottom end of the noise analyzer body 1. The disassembly rod 7 is provided with threads. When working, the worker holds the noise analyzer body 1, and the noise analyzer body 1 is connected to the placement box 2 through the elastic rope 6 to prevent the noise analyzer from falling out of hand.

[0049] Secondly, the hanging mechanism includes a placement slot 8, a limiting belt 9 and a supporting bracket 10. The placement slot 8 is fixedly connected in the placement box 2, the limiting belt 9 is fixedly connected to the side wall of the placement box 2, and the supporting bracket 10 is fixedly connected to the side wall of the placement box 2. The supporting bracket 10 is located below the limiting belt 9. When the worker performs noise analysis, the hanging belt 3 is tied around the waist. When it is inconvenient to hold the noise analyzer, the noise analyzer is placed in the placement box 2. The placement slot 8 can limit the noise analyzer body 1 to keep the noise analyzer upright. The limiting belt 9 and the supporting bracket 10 cooperate to place other tools on the supporting bracket 10, which is more convenient for noise analysis work.

[0050] Again, the temporary sampling mechanism includes a threaded rod 11, a second mounting tube 12, a third mounting tube 13, a mounting seat 14 and a fixing component. The threaded rod 11 is fixedly connected to the bottom end of the mounting tube 1 4, the second mounting tube 12 is slidably connected in the mounting tube 1 4, the third mounting tube 13 is slidably connected in the mounting tube 2 12, the mounting seat 14 is fixedly connected to the top of the mounting tube 3 13, and a thread is provided inside the mounting seat 14. The fixing component is installed on the mounting tube 1 4, the second mounting tube 12 and the third mounting tube 13. The thread inside the mounting seat 14 cooperates with the thread of the disassembly rod 7, so that the noise analyzer body 1 can be installed on the mounting seat 14. By cooperating with the mounting tube 1 4, the second mounting tube 12 and the third mounting tube 13, the height of the noise analyzer can be increased, and then the height can be fixed by the fixing component. Noise analysis can be temporarily performed without holding it, which is more convenient for scenarios where it is inconvenient to hold the noise analyzer.

[0051] Among them, the fixing component includes a limiting hole and a limiting nail 15. There are multiple limiting holes, and the multiple limiting holes are opened on the mounting tube 1 4, the mounting tube 2 12 and the mounting tube 3 13. There are multiple limiting nails 15, and the multiple limiting nails 15 are slidably connected in the limiting holes. When the height of the mounting tube 1 4, the mounting tube 2 12 and the mounting tube 3 13 is adjusted to be appropriate, the limiting nails 15 are inserted into the limiting holes to fix the height.

[0052] Finally, the hanging strap 3 is set to be an adjustable cloth hanging strap 3, and the top of the placement box 2 is provided with a threaded matching hole that matches the threaded rod 11.

[0053] In this embodiment, when the worker performs noise analysis work, he first hangs the placement box 2 on his waist through the hanging strap 3, and then holds the noise analyzer body 1. The noise analyzer body 1 can be placed in the placement box 2 at any time as the work needs it. It has the advantages of convenience and portability, and the noise analyzer body 1 can be screwed into the mounting seat 14. The noise analyzer can be temporarily placed on the mounting tube to detect noise by adjusting the extension and retraction of the mounting tube 1 4, the mounting tube 2 12 and the mounting tube 3 13, which is more suitable for noise analysis in various work scenarios.

[0054] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
