Technical Field
The invention relates to the technical field of bolt structures, in particular to a reusable check bolt and a using method thereof.
Background
In the processes of modern industrial production, building construction and daily life of people, people usually need to use a bolt part, and fix two structures by adopting a bolt connection mode so as to facilitate production and life; but the movable connection of the bolt can lead to the loosening of the nut, and no matter how tight the nut is screwed, the bolt can be released due to vibration and use, so that production accidents or inconvenience for life are caused;
in order to achieve the effect of bolt fastening, the prior art adopts the following structures to overcome the defect of bolt tripping:
① spring leaf structure is arranged below the nut, which increases the reverse return pressure of the nut when the nut is screwed on the bolt, so as to increase the friction force between the threads;
although the structure overcomes the defect of nut tripping to a certain extent, the structure cannot be guaranteed to be applied to equipment with frequent vibration, such as trains, machine tools, elevators, airplanes and the like, and anyone can easily unscrew the equipment by using a conventional tool to steal or destroy the equipment;
② the nut is fixed by spot welding after being screwed, namely the nut is welded on the bolt after the nut is screwed;
although the mode overcomes the defect that the nut is not enough to be released in the prior art, but the thread is damaged due to spot welding, the irreversible fixing mode greatly reduces the defects that the equipment cannot be disassembled and the bolt can only be destructively disassembled when the equipment is overhauled in the later period;
③ application No. 200720087750.2, a novel non return bolt for overcoming the disadvantages existing in the prior art, the utility model aims to provide a non return bolt capable of preventing theft, the utility model discloses non return bolt is connected with mounting nut (3) on the top rivet-shaped half round head (2) of bolt body (1), is equipped with countersunk head dome (4) on the lower part of rivet-shaped half round head (2), is equipped with a groove between rivet-shaped half round head (2) and mounting nut (3).
