Description

Technical Field

[0001] The utility model relates to the technical field of air compressor noise reduction, in particular to an air compressor noise reduction device. Background Art

[0002] An air compressor is a device used to compress gas. It is a device that converts the mechanical energy of a prime mover (usually an electric motor) into gas pressure energy. Through one of several methods, the air compressor forces more and more air into the air tank, thereby increasing the pressure. When the tank pressure reaches its designed upper limit, the air compressor will shut down.

[0003] However, in the prior art, the existing air compressor will generate a lot of noise during normal operation. In order to reduce the noise, most methods are to seal it in a closed box to reduce the noise. However, sealing the air compressor in a box will increase the overall volume of the device and will also cause the moving wheels of the air compressor to be unusable, thereby increasing the difficulty of moving the entire device and making it inconvenient to carry. Utility Model Content

[0004] The purpose of the utility model is to solve the shortcomings existing in the prior art: using a box to seal the air compressor increases the overall volume of the device and also makes the moving wheels of the air compressor unusable, thereby increasing the difficulty of moving and transferring the overall device and making it inconvenient to carry.

[0005] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: an air compressor noise reduction device, comprising an air compressor body, a fixed block is fixed on one side of the air compressor body, and a No. 1 electric telescopic rod is fixed on the side of the fixed block, a movable frame is fixed on one end of the No. 1 electric telescopic rod, and the movable frame is connected through the side block of the air compressor body, a moving wheel is fixed on the lower end surface of the movable frame, a sound insulation box is fixed on one end of the fixed block, an air outlet is fixed on one side of the sound insulation box, and the air outlet is connected to the air compressor body, an air exhaust port is provided on the other side of the sound insulation box, a sound insulation door panel is slidably connected to one side of the sound insulation box, a through port is provided at the bottom of the sound insulation box, and a movable groove is provided in the sound insulation box near the through port, a connecting rod and a sound insulation blocking plate are slidably connected in the movable groove, and the connecting rod is fixedly connected to the sound insulation blocking plate, a pull-out rod is provided on one side of the sound insulation box, and the pull-out rod is fixedly connected to the sound insulation blocking plate, and the number of the pull-out rods is set to two.

[0006] As a preferred embodiment, the sound insulation box and one side of the sound insulation door panel are both fixedly connected with sound absorbing cotton.

[0007] As a preferred embodiment, a No. 2 electric telescopic rod is fixed to the top of the soundproof box, and one end of the No. 2 electric telescopic rod is fixedly connected to the soundproof door panel.

[0008] As a preferred embodiment, a clamping block is fixedly connected to one side of the sound insulation blocking plate, and the clamping block is clamped and connected to the sound insulation box body.

[0009] As a preferred implementation, one end of the two pull rods is fixedly connected to a fixed cross bar.

[0010] Compared with the prior art, the advantages and positive effects of the utility model are:

[0011] The utility model completes the closing and opening of the through opening by driving the sound insulation blocking plate to move forward and backward through the push-pull draw rod. When the through opening is closed and the sound insulation door plate is closed, it is ensured that the device as a whole has good sealing performance, so that the air compressor body has a good noise reduction effect.
