Description

Technical Field

[0001] The utility model relates to the technical field of vacuum equipment, in particular to a novel locking device for vacuum equipment. Background Art

[0002] New vacuum equipment refers to equipment used for operation or processing in a vacuum environment. It is a device that generates, improves and maintains a vacuum, including vacuum application equipment and vacuum acquisition equipment. The vacuum equipment can extract gas from a container or space to form a vacuum state therein to meet specific process or experimental requirements. When the vacuum equipment is in use, a locking device is required to ensure that the equipment remains tightly and safely closed in a vacuum environment. Existing locking devices usually use mechanical locking to tightly seal the sealing plate and the vacuum box during use. Since the material will expand or contract when the temperature changes, there is a tiny gap between the door panel and the vacuum box. The leakage of internal air causes the vacuum degree in the vacuum box to decrease, reducing the overall sealing. The vacuum box is susceptible to safety risks caused by unstable internal pressure, which increases the risk of equipment use. Therefore, we propose a new vacuum equipment locking device to solve the above-mentioned problems. Utility Model Content
