[0002] The vacuum pump of a vacuum furnace is one of the key components to ensure the vacuum environment in the furnace. The vacuum pump is one of the key components to create and maintain the vacuum environment. It is usually installed at the bottom or side of the vacuum furnace and connected to the furnace chamber through pipelines. When in use, it is necessary to use an installation fixing structure to limit and fix the vacuum pump pipeline, safely support the vacuum pump and pipeline to prevent vibration or displacement during operation.

[0003] However, the vacuum pump pipeline installation and fixing structure of most vacuum furnaces now has the following problems:

[0004] First, the existing vacuum furnace vacuum pump pipeline installation fixed structure, when in use, the pipeline is mostly suspended on the ground or wall and other locations, the suspended pipeline is easily affected by external forces to bend or break, and it is inconvenient to support and fix according to the suspension distance.

[0005] Second, the existing vacuum furnace vacuum pump pipeline installation fixing structure cannot be arranged and limited when multiple sets of pipelines are used and fixed, and the pipelines are of different sizes, which makes it inconvenient to fix and arrange the pipelines of different sizes.

[0006] Therefore, we make improvements to this and propose a vacuum pump pipeline installation and fixing structure for a vacuum furnace. Utility Model Content
