Abstract
The utility model relates to a mechanical connecting part. A section of contrarotating screw thread is arranged at the lower end of the rotating screw thread, the outside of the contrarotating screw thread is provided with a contrarotating anti-loosing screw nut, and the screw bolt can not loose after being fastened in the way. The utility model which has the advantages of simple structure, convenient use, firm connection, etc. is suitable for connecting various easily loosing parts.
Description
The utility model relates to mechanical connecting element.
Normally used standard link, use a period of time or vibrated after usually produce loosening phenomenon, so just often the someone overhauls with fastening, usually add a spring pad in order to address this problem between packing ring and nut, but fastening effect is also unsatisfactory.
The purpose of this utility model is: a kind of fastening effective, simple in structure, easy to use anti-loosening bolt is provided.
The utility model is in the lower end of rotation screw thread one section counterrotating screw thread to be set, counterrotating screw thread outside be provided with one can counterrotating anti-loosening nut.
The utlity model has simple in structure, easy to use, fastening advantage such as effective.
Accompanying drawing 1 is a structural representation of the present utility model;
Accompanying drawing 2 is main pseudosections of the present utility model.
Accompanying drawing the 1, the 2nd, embodiment of the present utility model promptly connects one section counterrotating screw thread (6) in the lower end of rotation screw thread (5), put in the outside of counterrotating screw thread (6) again one can counterrotating anti-loosening nut (1).
During use, on screw rod (4), be inserted in earlier packing ring (3), on rotation screw thread (5), screw tightening nut (2) immediately, on counterrotating screw thread (5), be inserted in anti-loosening nut (1) again and oppositely screw, very good with the bolton effect that this mode is fastening.
