Description

Technical Field

[0001] This utility model mainly relates to the field of engine technology, specifically a base for engine units. Background Technology

[0002] An engine is a device that converts other forms of energy (such as the chemical energy of fuel, electrical energy, etc.) into mechanical energy. It is the power core of vehicles, aircraft, ships, generators, and other equipment. Engines are usually used in conjunction with a mounting base, which is a mechanical structure that fixes and supports the engine. It is typically installed between the engine and the vehicle frame, ship hull, or equipment base. Its core function is to stabilize and fix the engine, while reducing vibration transmission, protecting other components, and improving operational smoothness.

[0003] In summary, the existing technology, such as the fiberglass marine engine base disclosed in CN214002019U, includes an engine mounting base body. Supporting channel steels are integrally formed on both the front and rear sides of the engine mounting base body, extending along the length of the body. A horizontally positioned intermediate partition plate is provided on the channel wall at the center of the supporting channel steel. Bolt anti-loosening devices are provided above and below the intermediate partition plate. Each bolt anti-loosening device includes a horizontally positioned compression limiting plate and two symmetrically positioned, vertically fixed screws on the intermediate partition plate. A threaded sleeve is rotatably connected to the compression limiting plate opposite the screws, and the threaded sleeve and the corresponding screw are threadedly connected. This invention has a good effect in preventing bolt loosening and is convenient for installation and operation, bringing convenience to the user.

[0004] In summary, existing engine mounts have a good effect in preventing bolts from loosening, but they are not convenient for adjusting the height of the engine, and it is also inconvenient to remove and drain the engine oil pan later. Therefore, a new type of engine mount is proposed. Utility Model Content

A first shock-absorbing pad 307 is provided on the top of the third channel steel 305. The motor mounting bracket 4 is fixedly installed above the first shock-absorbing pad 307. The first shock-absorbing pad 307 is prior art and will not be described in detail.

[0030] Specifically, the first channel steel 101 is connected to the first support leg 7 through the second shock-absorbing connector 6, and the first channel steel 101 is connected to the second support leg 801 through the third shock-absorbing connector 8.
