Description
Technical Field
The utility model relates to a screw technical field specifically is an anti-loosening bolt.
Background
At present, as a standard element for fixed connection, bolts are almost everywhere visible in life, but at present, the bolts often have the phenomena of loosening of nuts or connecting pieces and unstable connection when being connected and fixed.
SUMMERY OF THE UTILITY MODEL
The technique that exists is not enough to the aforesaid, the utility model aims at providing an anti-looseness bolt, it sets up one in the bolt and is used for spacing screw for the bolt can not become flexible again when connecting, has solved nut or connecting piece not hard up, has connected unstable problem.
In order to solve the technical problem, the utility model adopts the following technical scheme:
the anti-loosening bolt comprises a bolt and a screw, wherein the direction of an external thread of the screw is opposite to that of the external thread of the bolt, a through long groove is formed in a screw rod of the bolt, an internal thread matched with the external thread of the screw is arranged in the long groove, and a rotating plane matched with the external thread of the bolt is arranged on the side wall of the screw.
The beneficial effects of the utility model reside in that: according to the design, the screw rod of the bolt is provided with the long groove, the screw opposite to the thread of the bolt is arranged in the long groove, and the nut or the connecting piece on the bolt can be effectively limited and fixed by rotating the screw, so that the nut or the connecting piece cannot be loosened, the installation is convenient, and the connection is more stable.
