Technical Field

[0001] The utility model relates to the technical field of sound insulation and noise reduction, in particular to a sound insulation and protection structure for an air compressor. Background Art

[0002] The professional term air compressor is the main body of the air source device. It is a device that converts the mechanical energy of the prime mover into gas pressure energy. It is a compressed air pressure generating device. During the production and use of the air compressor, it has high noise level, prominent low frequency, long transmission distance, and large pollution range, which can cause dizziness, nausea, tachycardia, high blood pressure and other symptoms.

[0003] Publication No. CN109441764A discloses a sound insulation protection device for an air compressor, which absorbs part of the noise by setting a sound-absorbing layer, and then sets a sound insulation layer to greatly reduce the propagation and diffusion of the noise. The outermost layer is set as an outer protective layer to protect the sound insulation layer from dust entering and thus affecting the purpose of reducing noise. The high-temperature resistant glass is set to use an inner layer of glass, a vacuum layer and an outer layer of glass. Since there is no propagation medium in the vacuum layer, it prevents the transmission of noise, thereby reducing the propagation of noise. However, the patent still has the following problems in actual use:

[0004] A sound-absorbing layer is provided to absorb part of the noise, a sound-insulating layer is provided again to greatly reduce the propagation and diffusion of the noise, an outer protective layer is provided on the outermost layer to protect the sound-insulating layer from dust that enters and affects the purpose of reducing the noise, and high-temperature resistant glass is provided using an inner glass, a vacuum layer and an outer glass. The vacuum layer has no propagation medium and thus prevents the transmission of noise, thereby reducing the propagation of noise. However, when installing and disassembling the protective cover, bolts are used for installation and disassembly, which makes it inconvenient for the staff to install and disassemble the protective cover, thereby reducing the installation efficiency of the protective cover.

[0005] A sound insulation and protection structure for an air compressor is proposed to solve the above-mentioned problems. Utility Model Content

A second spring 507 is sleeved on one side surface of the limiting rod 506 near the bottom. A fitting plate 508 is fixedly connected to the bottom surface of the second spring 507. The top surface of the second spring 507 is fixedly connected to the extension plate 505. The bottom surface of the fitting plate 508 is fitted and connected to the clamping rod 502. The fitting plate 508 is connected with the limiting rod 506 through and through. A limiting groove 509 is provided on the top surface of the clamping rod 502. The limiting groove 509 is engaged and connected with the limiting rod 506. Figure 3-5 As shown, after the limit rod 506 is pulled to separate the limit rod 506 from the limit groove 509, the card rod 502 is pulled to separate the card rod 502 from the card groove 9, and after the card rod 502 is pulled to a certain position, the limit rod 506 is loosened so that the limit rod 506 descends under the action of the second spring 507, so that the limit rod 506 and the limit groove 509 are re-engaged together, so that the card rod 502 can be limited. At the same time, after the card rod 502 has moved, the protective cover 4 is sleeved on the top of the body 1 so that the card groove 9 on the protective cover 4 is aligned with the card rod 502 to form a horizontal line, and then the limit rod 506 is pulled to make the limit rod 506 align with the limit groove again. 509 is separated, so that the locking rod 502 moves under the action of the first spring 503 and returns to its original position, so that the locking rod 502 is engaged with the locking groove 9, thereby completing the installation of the protective cover 4.
