However, the bolts of the present day often have the phenomenon that nuts or connecting pieces are loosened and the connection is unstable when the bolts are connected and fixed.
The applicant discloses a locking bolt in the Chinese patent application number 2020216227745, which comprises a bolt and a screw, wherein the external thread of the screw is opposite to the external thread of the bolt, a through long groove is formed in the screw rod of the bolt, an internal thread matched with the external thread of the screw is arranged in the long groove, and a rotation plane matched with the external thread of the bolt is arranged on the side wall of the screw. According to the utility model, 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 loosen, the installation is convenient, and the connection is more stable.
However, in the above conventional technique, the bolts need to be separately sealed when the seal is fastened, which is inconvenient to install and use.
Disclosure of Invention
Aiming at the technical defects, the utility model aims to provide the anti-loosening bolt, which well solves the problem that the prior anti-loosening bolt is inconvenient to use because additional sealing treatment is needed when a sealing element is fastened by the anti-loosening bolt.
In order to solve the technical problems, the utility model adopts the following technical scheme:
the utility model provides a locking bolt which comprises a bolt and a positioning screw, wherein the external thread of the positioning screw is opposite to the external thread of the bolt in direction; the bolt is provided with a through hole; an internal thread matched with the external thread of the positioning screw is arranged in the through hole; the side wall of the positioning screw is provided with a rotation plane which is matched with the external thread of the bolt;
the side wall of the bottom of the screw rod of the bolt is close to the position of the through hole, a positioning hole is transversely formed in the side wall of the bottom of the screw rod of the bolt and is used for bringing convenience to contact between the positioning screw and the nut or the fastener, and effective secondary limiting fixation can be realized on the nut or the connector on the bolt by rotating the positioning screw, so that the nut or the connector cannot loosen.
Preferably, the through hole on the bolt is eccentrically disposed.
The utility model has the beneficial effects that: the anti-loosening bolt is simple in structure, the positioning hole is formed in the bottom, and through the arrangement of the eccentric through hole, additional sealing treatment is not needed during use, the anti-loosening bolt is convenient to install, the problem that the existing anti-loosening bolt is inconvenient to use due to the fact that additional sealing treatment is needed during fastening of a sealing piece is solved, meanwhile, the positioning hole is formed in the bottom, the positioning screw is convenient to contact with a nut or a fastening piece, effective secondary limiting and fixing of the nut or the connecting piece on the bolt can be achieved through rotation of the positioning screw, and the nut or the connecting piece cannot loosen.

Detailed Description
The following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present utility model, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.
Embodiment 1, as shown in fig. 1 to 3, a locking bolt comprises a bolt 1 and a set screw 2, wherein the external thread of the set screw 2 is opposite to the external thread of the bolt 1; the bolt 1 is provided with a through hole 3; an internal thread matched with the external thread of the positioning screw 2 is arranged in the through hole 3; a rotation plane 21 which is matched with the external thread of the bolt 1 is arranged on the side wall of the positioning screw 2;
furthermore, the side wall of the bottom of the screw rod of the bolt 1 is provided with a positioning hole 4 near the position of the through hole 3 in a transverse direction, and the positioning hole can be matched with the bottom of the through hole 3 to form a positioning slot hole for bringing convenience to contact between a positioning screw and a nut or a fastener, and the nut or the connector on the bolt can be effectively and secondarily limited and fixed by rotating the positioning screw, so that the nut or the connector cannot be loosened.
Further, in an embodiment, the through hole 3 on the bolt 1 is eccentrically disposed.
When the nut or the connecting piece is installed, the positioning screw 2 is rotated and screwed into the through hole 3, the deep length of the positioning screw 2 is adjusted, or the positioning screw 2 is adjusted so that the rotating plane 21 is flush with the top end of the positioning hole 4, so that the nut or the connecting piece is convenient to install, and after the nut or the connecting piece is installed, the positioning screw 2 is rotated and screwed out; the external thread of the positioning screw 2 is opposite to the external thread of the bolt 1 in direction, and the eccentric positioning screw rod generates a tensioning effect after rotating, so that the external thread of the positioning screw 2 plays a role in limiting and fixing a nut or a connecting piece, and the connection cannot be loosened.
The anti-loosening bolt is simple in structure, the positioning hole is formed in the bottom, and through the arrangement of the eccentric through hole, additional sealing treatment is not needed during use, the anti-loosening bolt is convenient to install, the problem that the existing anti-loosening bolt is inconvenient to use due to the fact that additional sealing treatment is needed during fastening of a sealing piece is solved, meanwhile, the positioning hole is formed in the bottom, the positioning screw is convenient to contact with a nut or a fastening piece, effective secondary limiting and fixing of the nut or the connecting piece on the bolt can be achieved through rotation of the positioning screw, and the nut or the connecting piece cannot loosen.
