Description

Technical Field

[0001] The utility model relates to the technical field of oil mist lubrication, in particular to a hose connector device of an oil mist lubrication system. Background Art

[0002] Oil mist lubrication technology uses the energy of compressed air to atomize liquid lubricating oil into small particles of 1um-3um, which are suspended in the compressed air to form a mixture (oil mist). Under its own pressure energy, the mixture is transported to various required parts through transmission pipelines to provide a new lubrication method.

[0003] In oil mist lubrication devices, compressed gas flows at high speed between hoses, and the connection between these hoses relies on hose connectors to ensure the integrity of the system. However, traditional hose connectors mostly rely on threaded sleeves for connection. After long-term operation, this connection method is prone to loosening due to wear or vibration, thereby reducing the sealing performance and posing a potential threat to the normal operation of the device.

[0004] Therefore, a hose connector device for an oil mist lubrication system is needed to solve the above problems. Utility Model Content
