Abstract
The utility model discloses a detachable hollow bolt, which comprises a bolt, wherein a cavity is formed in the bottom inner wall of the bolt, a supporting rod is fixedly connected to the inside of the cavity, a connecting rod is fixedly connected to the upper surface of the bolt, a rotating sheet is fixedly connected to the outer surface of the connecting rod, an opening is formed in the outer surface of the connecting rod, a fixing sheet is connected to the outer surface of the connecting rod in a threaded manner, a groove is formed in the upper surface of the fixing sheet, and a limiting rod is fixedly connected to the upper surface of the connecting rod. Through the structure, the bolt and the fixing piece can be detached, the bolt can be fixed, and meanwhile, when the bolt is rusted, the fixing piece and the bolt can be rotated respectively, so that torsion is facilitated.
Description
Technical Field
The utility model relates to the technical field of bolts, in particular to a detachable hollow bolt.
Background
The bolt is a cylindrical threaded mechanical part, and consists of a head part and a cylindrical body with external threads, and the head part and the cylindrical body are matched with a nut for fastening and connecting the two cylindrical body with through holes, and the technical scheme provided by the utility model with the application number of CN201820950422.9 is that the problem that the bolt is difficult to disassemble in the process of rusting can occur.
Disclosure of Invention
The utility model aims to at least solve one of the technical problems in the prior art, and provides a detachable hollow bolt, which can be detached from a fixing piece, can fix the bolt and simultaneously can rotate respectively with the fixing piece when the bolt is corroded, so that the bolt is convenient to twist.
In order to achieve the above object, the present utility model also provides a detachable hollow bolt having the above structure, comprising:
the inner bottom wall of the bolt is provided with a cavity, a supporting rod is fixedly connected in the cavity, a connecting rod is fixedly connected to the upper surface of the bolt, and a rotating plate is fixedly connected to the outer surface of the connecting rod;
the opening, the surface threaded connection of connecting rod has the stationary blade, the upper surface of stationary blade is provided with the recess, the upper surface fixedly connected with gag lever post of connecting rod.
According to the detachable hollow bolt, the number of the supporting rods is multiple, and the supporting rods are distributed up and down and used for avoiding deformation of the bolt.
According to the detachable hollow bolt, the number of the rotating pieces is two, the rotating pieces are distributed left and right, and the shape of the rotating pieces is the same as that of the grooves and is used for facilitating the rotation of the bolt.
According to the detachable hollow bolt, the limiting rod is perpendicular to the rotating plate in direction, and the length of the opening is greater than that of the limiting rod for facilitating the taking of the fixing plate.
According to the detachable hollow bolt, the distance from the upper surface of the rotating piece to the upper surface of the connecting rod is greater than the thickness of the fixing piece, so that the fixing piece is convenient to take down.
According to the detachable hollow bolt, the opening is perpendicular to the groove.
Additional aspects and advantages of the utility model will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the utility model.
