The invention provides a mounting structure and a device. The mounting structure comprises a mounting frame (50) and a damping mat, wherein the mounting frame is provided with a mounting hole (51) andis used for being connected with a to-be-installed part, the mounting frame (50) sleeves a part of the damping mat through the mounting hole (51), the damping mat is used for being connected with a fixing part, the mounting frame (50) is provided with a limiting structure (52) for limiting the rest parts of the damping mat, and when the to-be-installed part is impacted, the damping mat makes contact with the limiting structure (52) so as to increase the contact area between the damping mat and the mounting frame (50). According to the mounting structure, when the to-be-installed part is impacted, the damping mat makes contact with the limiting structure, so that the contact area between the damping mat and the mounting frame is increased, the part, located in the mounting hole, of the damping mat is prevented from being excessively stressed and damaged, the service life of the damping mat is prolonged, the reliability of the damping mat is improved, and the vibration resistance and impact resistance of a compressor are improved.
