A segmented bolt

Abstract

The invention discloses a segmented bolt, which comprises a connecting bolt body and a plug with various lengths; the connecting bolt body is used to connect a thick workpiece 1 and a workpiece 2, and the workpiece 2 is provided with a through upper threaded hole for For screwing into the connecting bolt body, the workpiece is provided with a corresponding lower threaded hole; the connecting bolt body is provided with a hexagonal hole inside, and the hexagonal hole is used to insert a wrench to rotate the connecting bolt; the plug includes a shell with an external thread and a The rubber part in the housing is provided with a through hole for the wrench to pass through. The side wall of the through hole is provided with a number of convex strips. The bolt of the present invention can reduce the length of bolts used for connection, thereby reducing the overall weight of the connected workpieces; has a hidden function to avoid collision with other workpieces; and has a self-locking function to avoid the occurrence of wrong rotation, thereby avoiding accidents.

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.
