Description

Full-coating noise-reduction and sound-insulation pad for engine Technical Field The utility model relates to the technical field of noise reduction and sound insulation, in particular to a full-coating noise reduction and sound insulation pad for an engine. Background A sound insulation mat is a material for blocking sound transmission, and reduces noise effects mainly by absorbing, reflecting or damping sound waves. The sound insulation type sound insulation wall is generally made of materials with elasticity and porous structures such as rubber, foam and fiber, can be designed into different thicknesses and forms according to different scene requirements, is used for floor sound insulation in home decoration so as to reduce noise interference under floors, is used for wrapping machines in industrial equipment so as to reduce running noise, and is used for paving a wall surface in a recording studio so as to improve acoustic environment and the like. The sound insulation device is simple and convenient to install, has obvious sound insulation effect, can effectively improve the quietness degree of a space, and is widely applied to the fields of construction, industry, entertainment and the like. During operation of an engine, noise generated during operation thereof has been a problem to be solved. Currently, in order to achieve effective noise reduction, people often add a sound insulation pad at the bottom of the engine, and this mode is mainly used for reducing noise generated between the engine and the ground due to vibration. However, the existing acoustic insulator mat arrangement has significant limitations in that it only focuses on the noise at the bottom of the engine, but ignores the noise generated by the self-vibration of the engine sidewall, resulting in that this noise is not effectively eliminated. From the logical sequence of noise generation, vibration generated when the engine works can be transmitted to the contact position of the bottom and the ground, the side wall of the engine can generate noise due to self vibration, the existing sound insulation pad only processes the bottom noise, and the problem of noise generated when the engine operates can not be completely solved obviously. Disclosure of utility model The utility model aims to solve the problems in the prior art, and provides a fully-covered noise-reduction and sound-insulation pad for an engine. In order to achieve the purpose, the fully-coated noise-reducing and sound-insulating pad for the engine comprises a side pad and a bottom pad, wherein one end of the side pad is fixedly connected with a lock rod, the end part of the lock rod is fixedly connected with a lock head at equal intervals, the other end of the side pad is provided with clamping grooves at equal intervals, the inner end parts of the clamping grooves are provided with notches, the width of the notches is larger than that of the lock head, the width of the lock head is larger than that of the clamping grooves, two ends of the side pad are wound to form a cylinder, the two ends of the side pad are fixed through buckling of the lock head and the clamping grooves, the side pad is coated on the side wall of the engine, and the bottom pad is butted with the bottom end of the side pad to realize coating of the bottom wall of the engine.
