Detailed Description

The present invention will be further described with reference to the accompanying drawings and the detailed description, and it should be noted that any combination of the embodiments or technical features described below can be used to form a new embodiment without conflict.

As shown in fig. 1-3: the utility model provides a diesel generating set vibration damping mount, includes outer container 1, be equipped with spring support device 2 in the

outer container

1, 2 one end fixed connection of spring support device are in 1 bottom of outer container, other end fixedly connected with kickboard 3, diesel generating set 4 is connected to 3 upper ends of kickboard, it has fluid 5 to pour into in the outer container 1, spring support device 2 supports 3 showy of kickboard on the fluid 5, the kickboard 3 through spring support device 2 elastic deformation with 5 absorption oscillations of fluid reduce its vibration range. During the use, pass through the bolt fastening with diesel generating set 4 on the kickboard 3, the kickboard 3 atress causes spring 23 in the spring support device 2 warp and produces the bounce, supports kickboard 3, under diesel generator vibrations, transmits spring 23, spring 23 reduces through elastic deformation the kickboard 3 vibrations.
