Segmented bolt

Abstract

The invention discloses a segmented bolt. The segmented bolt comprises connecting bolt bodies with various lengths and plugs; the connecting bolt bodies are used for connecting a workpiece I to a workpiece II with the thicker thickness, the workpiece II is provided with perforated upper threaded holes for screwing in the connecting bolt bodies, and the workpiece I is provided with corresponding lower threaded holes; hexagonal holes are formed in the inner part of the connecting bolt bodies, and the hexagonal holes are used for inserting a wrench to rotate the connecting bolt; and the plugs comprise shells provided with external threads and rubber parts arranged in the shells, the rubber parts are provided with through holes for the wrench to pass, the side wall of the through holes are provided with a plurality of convex strips, and the convex strips are mutually stacked to cover the through holes to prevent external impurities from entering, and the top of the shell is provided with afour-angle counterbore. According to the segmented bolt, the length of the bolt used for connection can be reduced, so that the overall weight of the connected workpiece is reduced; the bolt has a hidden function, so that collision to other workpieces is avoided; and the self-locking function is also provided, the occurrence of muffed rotation can be avoided, and therefore accidents are avoided.

Description

technical field [0001] The invention relates to a segmented bolt. Background technique [0002] Bolt: A mechanical part, a cylindrical threaded fastener with a nut. A type of fastener consisting of a head and a screw (a cylinder with external threads), which needs to be matched with a nut to fasten two parts with through holes. This connection form is called 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] At present, during assembly work, there is a work flow, which is to connect two thicker plate workpieces together through bolts. The length of the bolt used to connect the two workpieces only needs to meet the work requirements, and it is not necessarily required to penetrate the two workpieces. If the bolt is too long, one will increase the overall weight of the two workpieces, and the other will make the screw-in time too long, which will increase the working time. [...

AI Technical Summary

Problems solved by technology

If the bolts are too long, one will increase the overall weight of the two workpieces, and the other will make the screwing time too long, which will increase the working time

[0004] In addition, during design, in order to prevent the protruding bolt head from colliding with other workpieces, counterbore holes may be processed at the screw hole port of the plate, and the bolt heads are hidden in the counterbore, but this will increase the additional processing steps of the plate workpiece

And the bolt head is used to put into the inner hole of the wrench, it will be dirty, and if things go on like this, the inner hole will be full of dirt, making it impossible to insert the wrench

[0005] Finally, the current common bolts do not have the ability to prevent mis-rotation. When engineers perform maintenance or other vibration-prone working conditions, they will rotate, causing the bolts to loosen, resulting in accidents.
