[0002] Refrigeration equipment includes air conditioners, which are a type of refrigeration equipment mainly used to regulate indoor temperature and humidity. They transfer indoor heat to the outside through the refrigeration system, thereby lowering the indoor temperature. At the same time, they can also remove some moisture from the air, thereby reducing indoor humidity and making people feel cool and comfortable.

[0003] Currently, most air conditioner outdoor units are installed outdoors. When the outdoor unit is running, the vibration generated during startup can be clearly felt indoors. After prolonged use, the vibration and noise of the outdoor unit will increase, causing discomfort to people. Therefore, vibration-damping and sound-insulating pads are placed at the connection between the outdoor unit and the bracket to effectively reduce the vibration and noise generated during outdoor operation. However, the vibration-damping and sound-insulating pads are a single unit, which makes it inconvenient for personnel to adjust the position of the outdoor unit during installation, and the position of the vibration-damping and sound-insulating pads is not accurate with the positioning of the outdoor unit. To address these issues, we propose a noise reduction and vibration damping device for refrigeration equipment. Utility Model Content
