Abstract

The invention relates to the technical field of mechanical assembly, in particular to a split self-locking nut. The split self-locking nut comprises a first connecting block and a second connecting block located above the first connecting block, wherein a semi-circular first internal thread is formed in the center of the upper end of the first connecting block, and a semi-circular second internalthread matched with the first internal thread is formed in the center of the lower end of the second connecting block; a groove is formed in the middle of one side of the upper end of the first connecting block, first through holes are formed in two end surfaces of the groove, an inserting plate matched with the groove is arranged in the middle of one side of the lower end of the second connectingblock, and a second through hole matched with the first through holes is formed in the center of the inserting plate; a threaded hole is formed in the other side of the upper end of the first connecting block, and a step through hole matched with the threaded hole is formed in the other side of the lower end of the second connecting block. The split self-locking nut is convenient to use, good inself-locking performance and wide in practical range, and potential safety hazards are reduced.

Description

technical field [0001] The invention relates to the technical field of mechanical assembly, in particular to a split self-locking nut. Background technique [0002] Nuts are widely used assembly fasteners, but when ordinary nuts are used, especially in high-frequency, alternating and other vibration situations, the nuts will loosen or even fall off due to vibration. In order to prevent the nut from loosening and falling off and reduce potential safety hazards, a variety of nuts with self-locking functions have been derived. In the prior art, in order to improve the reliability of the self-locking nut, sometimes a flange is provided at one end of the nut to prevent the nut from loosening by increasing the frictional force; through holes, and insert cotter pins into the through holes. The reliability of the nut is improved to a certain extent by the way of setting the flange, but with the increase of the vibration frequency and the extension of the service time, it will stil...
