Abstract

The utility model discloses a locking nut for an exhaust system, which comprises a main nut, wherein four threaded sleeves are arranged at the top of the main nut in an array shape, the bottoms of the four threaded sleeves are fixedly connected with the top of the main nut, the top of the main nut is provided with a locking nut, and the locking nut is matched with the threaded sleeves. The anti-loose lock nut for the exhaust system provided by the utility model has the advantages that under a bumpy environment, the self-contained spring of the nut can provide continuous downward pressure, so that the anti-loose lock nut has stronger environmental adaptability, even if the bumpy intensity is too high, the sliding teeth at the bottom of the lock nut can still be fastened with the sliding tooth grooves, the lock nut is ensured not to rotate, after the bumpy condition is finished, the fastening effect on the bolt is still maintained under the double functions of the spring and the sliding teeth, the loosening caused by long-term use is avoided, and when the nut is required to be disassembled, the nut is not damaged, and the anti-loose lock nut can be reused.

Description

Locking nut for exhaust system Technical Field The utility model relates to the technical field of nuts, in particular to a locknut for an exhaust system. Background In the patent application with the application publication number of CN218760847U, the nut comprises a nut body and a reinforcing mechanism, wherein the nut body comprises a round head part and a hexagonal part, the round head part and the hexagonal part are welded, and the round head part and the hexagonal part are coaxially arranged. This locking nut that excels in through setting up strengthening mechanism, rotates the ring that cup joints after being connected this nut with other structures, makes the ring that cup joints slide in the outside of strengthening the arc board through the external screw thread for the opening part at strengthening the arc board top folds gradually, makes perpendicular notch gradually closed, through erecting notch department to the shrink, makes the inboard internal screw thread of strengthening the arc board receive tightening up, makes this nut and other structure connection inseparabler, makes this nut possess the locking advantage of high strength, has solved the problem of easy looseness. In the above patents or the prior art, the use of the nut is quite wide, and when the nut is used in an extreme environment where the nut is vibrated at high frequency or jolt for a long time, the fastener of the nut can vibrate for a long time to loosen the nut, so that the nut may fall off. Disclosure of utility model The utility model aims to provide a locking nut for an exhaust system, which solves the problem that the bumpy environment proposed in the background technology is easy to fall off. In order to achieve the purpose, the anti-loosening lock nut for the exhaust system comprises a main nut, wherein four threaded sleeves are arranged at the top of the main nut in an array mode, the bottoms of the four threaded sleeves are fixedly connected with the top of the main nut, the lock nut is arranged at the top of the main nut, and the lock nut is matched with the threaded sleeves. Further, one side of each of the four threaded sleeves is provided with large sliding teeth, the inner wall of the locking nut is provided with four large sliding teeth in an annular array shape, and the large sliding teeth of the locking nut are matched with the large sliding teeth of the threaded sleeve. Further, the top of the main nut is provided with a plurality of sliding tooth grooves in an annular array shape, the bottom of the locking nut is provided with a plurality of sliding teeth in an annular array shape, and the sliding teeth are matched with the sliding tooth grooves. Further, a baffle is arranged at the top of the main nut, and the bottom of the baffle is fixedly connected with the top of the main nut. Further, the baffle is matched with the threaded sleeve. Further, the bottom of baffle is provided with the spring, the bottom of spring and lock nut's top looks adaptation. Compared with the prior art, the anti-loose lock nut for the exhaust system has the advantages that the anti-loose lock nut for the exhaust system is reasonable, and has the following advantages: (1) Under the environment of jolting, the nut can provide continuous down force from the spring that takes, thereby have stronger environmental suitability, even jolting intensity is too big makes the nut appear becoming flexible, smooth tooth bottom the lock nut still can the lock nut tooth socket of buckling, ensure that lock nut does not appear rotating, after jolting the condition, under the dual function of spring and smooth tooth, still keep the fastening effect to the bolt, can not produce the not hard up because of long-term use, only need slightly pry up the lock nut when the nut is required to be dismantled, make its smooth tooth break away from smooth tooth socket alright anticlockwise screwing release locking state, can not cause the damage to the nut itself, repeatedly usable, when the bolt diameter has tolerance or model less, this lock nut also has certain adjustable frame volume, the bolt of different sizes has further reduced production and use cost, main nut and lock nut adopt the splayed nut design of same model size simultaneously, only need a spanner divide the twice to twist and can completely fasten the nut, the application scenario is more extensive, use operability is stronger, further improvement operator work efficiency.
