Loosening-prevention flange face bolt

Abstract

The invention discloses a loosening-prevention flange face bolt, and relates to the technical field of bolts. The loosening-prevention flange face bolt comprises a bolt tail, a first thread is mountedon the outer side of the bolt tail, a first bolt head is fixedly connected to the front end of the first thread, a handle hole is formed in the outer side of the first bolt head, a second thread is mounted on the inner wall of the handle hole, a handle rod is mounted on the right of the handle hole, the left end of the handle rod is inserted into the handle hole, the handle rod is matched with the handle hole, the outer side of the right end of the handle rod is provided with a third thread, the third thread is matched with the second thread, the handle rod and the handle hole are fixedly connected together through the second thread and the third thread, the left end of the handle rod is fixedly connected with a clamping plate, the clamping plate is in the handle hole, the right end of the handle is fixedly connected with a handle, according to the loosening-prevention flange face bolt, a force arm during whole rotation of the bolt can be increased, the rotation of the whole bolt is more easy, and the whole bolt can be screwed into the target position in a labor saving manner.

Description

technical field [0001] The invention relates to the technical field of bolts, in particular to an anti-loosening flange surface bolt. Background technique [0002] Fasteners are basic mechanical parts for connection. They have the advantages of simple construction, good mechanical performance, removable, fatigue resistance, and no loosening under dynamic loads. They are widely used in machinery, electric power, automobiles, construction, and railways. , bridges, ships, fire water supply systems, communication systems and other industries, used for the connection of important machinery, fasteners are also safety parts. Flange bolts are a kind of bolt connection pair, which are widely used in bridge construction, industrial and civil construction, heavy machinery such as cranes, high-end automobile engines, etc. [0003] In some specific conditions, it is necessary to remove the bolt from the target position, but sometimes the phenomenon of bolt slippage will occur. In such a...

Problems solved by technology

[0003] In some specific conditions, it is necessary to remove the bolt from the target position, but sometimes the phenomenon of bolt slippage will occur. In such a situation, it is difficult to remove the bolt from the target position without tools. Take it off, even with tools, it takes a lot of force to extract the bolts, which causes a certain amount of trouble to the required work
