Abstract
The invention relates to an anti-loosing and locking method of a bolt and nut with left and right-hand threads and is characterized in that one or two ends of the bolt or nut are designed as left and right-hand threads; the left and right-hand threads arranged at one or two ends of the bolt or nut can be screwed on leftwards and screwed off rightwards or can be screwed on rightwards and screwed off leftwards; the left and right-hand threads can be arranged in steps with different thickness; the left and right-hand threads can be screwed rightwards along the external diameter and screwed leftwards along the internal diameter or can be screwed leftwards along the external diameter and screwed rightwards along the internal diameter; the left and right-hand threads can be arranged below the bolt cap; and the external diameters of the left and right-hand threads can be smaller than or larger than the external diameter of the bolt cap. The effects of anti-loosing and locking are achieved through mutual reaction forces generated when the bolt and nut with left and right-hand threads are matched with each other.
Description
1, technical field
The present invention relates to a kind of interworking, assembling bolt nut, it is characterized in that about an end of bolt or nut or both-end are designed to, revolving screw thread.Its function is anti-loosening.
2, background technique
Bolt, nut are as connecting, fixing (standard) part is widely used in science and technology, production, processing and test etc. on numerous occasions and machinery and the instrument and apparatus.But the open defect of conventional bolt, nut is to use and is easy to generate looseningly in the process, and especially on vehicle that travels or dynamic instrument and apparatus, this loosening the lighter who is difficult for discovering influences normally carrying out of work, and weight person can lead to a disaster.
For preventing the generation of bolt, nut loosening phenomenon, the bolt of specific use is equipped with special-purpose " locking " nut, but this " locking " nut should punch on bolt, nut the while, twines after assembling again and ties up iron wire, and can not reuse, can not machinery and automatic production.
" locking " nut that also has is realized with encapsulating, can only disposablely use, and loading and unloading is inconvenient.
3, summary of the invention
Existing in order to overcome " locking " nut should punch on bolt, nut simultaneously, after assembling, twine again and tie up iron wire, and can not reuse and encapsulating " locking " nut can only disposablely use, and many defectives that loading and unloading are inconvenient the invention provides a kind of anti-loosening interworking, assembling bolt nut.
The right-handed thread that changes conventional bolt, nut revolves screw thread about being.Make the bolt that revolves screw thread about being processed into respectively, nut is worked in coordination, and the effect of can play connection, fixing can in use be played anti-loosening effect again.
The technological scheme that adopts is: revolve screw thread about an end of bolt or nut or both-end are designed to.
Revolve about end of bolt, nut or both-end setting screw thread be left-handed under the dextrorotation.
About end of bolt, nut or both-end setting, revolve screw thread and be in the dextrorotation left-handed down.
About revolve screw thread and be set to thickness other step type (outside thread) is arranged.
About revolve screw thread and be set to external diameter dextrorotation, internal diameter is left-handed.
About revolve screw thread to be set to external diameter left-handed, internal diameter dextrorotation.
About revolve the below that screw thread is arranged on nuts, its external diameter is less than the nuts external diameter.
About revolve the below that screw thread is arranged on nuts, its external diameter is greater than the nuts external diameter.
