Drawings
Fig. 1 is a schematic structural view of the present invention;
in the figure: 1 bolt head, 2 bolt rod parts, 3 oilholes, 4 oil ducts, 5 oil storage chambers, 6 tips, 7 fixed columns, 8 inserted bars and 9 jacks.
Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
As shown in fig. 1, a bolt convenient to fasten and dismantle, including integrated into one piece's bolt head 1 and bolt pole portion 2, 2 peripheries in bolt pole portion are provided with a plurality of oilholes 3, and a plurality of oilholes 3 are laid along the length direction of bolt pole portion 2, and a plurality of oilholes 3 all communicate in setting up at 2 inboard oil ducts 4 in bolt pole portion, 1 inboard side in bolt head is provided with oil storage chamber 5, oil storage chamber 5 relatively rotate connect in bolt head 1, the one end that oil duct 4 is close to bolt head 1 is provided with the most advanced 6 that can puncture oil storage chamber, oil storage chamber is arranged in directly over the oil duct for the bolt head rotates the back. Specifically, 1 middle part of shank of bolt head is provided with and is columniform spacing chamber, spacing intracavity rotates and is provided with fixed column 7, fixed column 7 lower extreme is provided with oil storage chamber 5, oil storage chamber 5 is semi-cylindrical. One side opposite to the oil storage cavity at the lower end of the fixing column can be provided with a semi-cylindrical part integrally formed with the fixing column, a space is arranged between the semi-cylindrical part and the oil storage cavity, and the oil duct and the tip end are located between the spaces. Furthermore, a through hole penetrating through the fixing column 7 from top to bottom is formed in the through hole, the oil storage cavity is avoided by the through hole, an inserting rod 8 is inserted into the through hole, an inserting hole 9 is formed in the lower portion of the fixing column on the inner side of the head of the bolt, and the inserting rod 8 is inserted into the inserting hole 9. Fixed the fixed column on the one hand, on the other hand also uses the fixed column to easily realize relative rotation.
