Description

Technical Field

[0001] The utility model relates to the technical field of fasteners, in particular to a dustproof bolt. Background Art

[0002] Bolt: A mechanical part, a cylindrical threaded fastener with a nut. It is a type of fastener consisting of a head and a screw. It must be matched with a nut to fasten two parts with through holes. This type of connection is called a bolt connection. If the nut is unscrewed from the bolt, the two parts can be separated, so the bolt connection is a detachable connection.

[0003] When the bolt is used, it needs to be installed inside the thread groove or used in conjunction with a nut. When in use, the bolt is usually placed in an exposed environment. Since most bolts are placed in an environment full of oil, the presence of a large amount of oil can easily cause the operating groove of the bolt to be blocked, thereby affecting the insertion of the screwdriver into the operating groove and affecting its normal rotation. For this reason, we propose a dust-proof bolt. Utility Model Content
