Problems solved by technology

[0003] The main purpose of the present invention is to provide a self-locking bolt. On the one hand, when the bolt is used to fasten the target object, the bolt becomes loose due to the vibration of the target object. On the other hand, the filling grease in the bolt hole is insufficient. The problem that it is difficult to be unscrewed from the bolt hole after being rusted

Abstract

The invention relates to the field of bolts, in particular to a self-locking bolt. The self-locking bolt comprises a nut, a screw rod is connected to the lower end of the nut, a fixing block is arranged at the upper end of the nut, rectangular openings are formed in the two sides of the fixing block at the upper end of the nut, drawing mechanisms are movably connected into the rectangular openings, the drawing mechanisms comprise drawing plates, vertical rods are connected to the two ends of the drawing plates, first springs are connected to one ends of the drawing plates, movable plates are connected to the lower ends of the vertical rods, through holes are formed in the surfaces of the movable plates, a locking mechanism is movably connected to the interior of the fixing block and comprises a stretching rod, a transverse rod is connected to the surface of the stretching rod, a locking rod is connected to the position, close to one end, of the surface of the transverse rod, and a supporting table is arranged at the bottom end inside the screw rod. According to the self-locking bolt, the bolt can be prevented from continuously rotating after being tightened, and the situation that the bolt is loosened is avoided.

Description

technical field [0001] The invention relates to the field of bolts, in particular to a self-locking bolt. Background technique [0002] A bolt is a mechanical part, a cylindrical threaded fastener with a nut, a type of fastener consisting of a head and a screw (cylindrical body with external threads), which needs to be matched with a nut. For fastening and connecting 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; on the one hand When the bolt is used to fasten the target, there is a situation that the bolt will loosen due to the vibration of the target, so there is a risk of loosening. On the other hand, the filling of the grease in the bolt hole is not sufficient. When the bolt is rusted, it is difficult to be removed from the bolt. In order to solve the above problems, we propose a self-locking bolt. Contents of the inv...
