Abstract
A kind of safety lock that prevents nut loosening, belong to machinery manufacturing technology field, adopt lock body, lock pin and screw to constitute the safety lock that prevents nut loosening, lock body and lock pin are one, are shaped as Ω shape, and the lock body internal surface is the circle of opening, internal thread is arranged, two lock pin have through hole respectively in the position of lock body opening on the lock pin, and screw is in through hole.During use, lock body is screwed in bolt, is adjacent to the nut of having tightened, again with screw tightening, lock body is fixed on the bolt tightly, nut has not just had the space that can become flexible like this.The utility model is simple in structure, and is easy for installation, can prevent nut loosening effectively, and using effect is safe and reliable.
Description
Technical field:
The utility model belongs to machinery manufacturing technology field, is a kind of securing means that prevents nut loosening.
Background technique:
It is very general that the Placement that adopts screw bolt and nut that two mechanical parts are fixed as one is used at present.But nut screws after a while, owing to friction and oscillation phenomenon can occur in the machine work process, cause nut loosening, untimely processing can cause mechanical failure, and cisco unity malfunction also may have an accident.At present, the method that a kind of solution is arranged is to be with elastic sheet metal on bolt, and together fastening with nut, effect is undesirable.
Summary of the invention:
The technical problems to be solved in the utility model is to disclose a kind of safety lock that can prevent nut loosening effectively.
The scheme of the utility model technical solution problem is to adopt lock body, lock pin and screw to constitute the safety lock that prevents nut loosening, lock body and lock pin are one, be shaped as Ω shape, the lock body internal surface is the circle of opening, internal thread is arranged, two lock pin have through hole respectively in the position of lock body opening on the lock pin, and screw is in through hole.During use, lock body is screwed in bolt, is adjacent to the nut of having tightened, again with screw tightening, lock body is fixed on the bolt tightly, nut has not just had the space that can become flexible like this.
The utility model is simple in structure, and is easy for installation, can prevent nut loosening effectively, and using effect is safe and reliable.
Description of drawings:
Accompanying drawing is the utility model structural representation.
The utility model is made of lock body 1, lock pin 2 and screw 5, and lock body 1 and lock pin 2 are one, are shaped as Ω shape, lock body 1 internal surface is the circle of opening, 3, two of internal threads lock pin 2 is arranged respectively in the position of lock body 1 opening, on the lock pin 2 through hole 4 is arranged, screw 5 is in through hole 4.
