Description
Technical Field
The utility model relates to a fastener technical field, concretely relates to lubricated type bolt.
Background
In order to avoid the problem that the bolt is rusted and clamped with the fastened piece after long-term use, part of the bolt is provided with an oil passage on the screw rod to lubricate between the bolt and the fastened piece, such as the bolt disclosed in the application number 201520691737.2. Although the bolt can prevent the problem that the bolt and a fastened part are clamped, the following problems still exist after long-term use is proved: in order to ensure that the bolt and the fastened piece are always in a lubricating state, lubricating oil needs to be injected into the oil duct, and due to threaded connection, a gap exists between the screw rod and the fastened piece, so that the phenomenon of oil leakage is easy to occur during use. When lubricating oil is not continuously filled in the oil duct, and when the oil is filled into the oil duct when the bolt is rusted, the lubricating oil can slowly permeate into the oil duct, so that long lubricating time is needed.
