If the nut is unscrewed from the bolt, the two parts can be separated, so the bolt connection is a detachable connection. However, in the actual use of the existing bolts, due to the vibration between the connecting parts, the bolts have been in service for a long time. After that, it is easy to loosen, which will affect the stability between the connecting parts, and even cause the connecting parts to loosen and fall off, resulting in casualties. Therefore, it is necessary to propose an anti-loosening bolt assembly

Abstract
The invention discloses a check bolt assembly which comprises a bolt, a nut, a first check washer and a second check washer. A step segment, a thread segment and an open groove are sequentially arranged on a stud of the bolt from top to bottom. A nut is arranged on the thread segment. The first check washer is arranged on the step segment. A blind hole extending upwards is formed in the center ofthe open groove. The second check washer is arranged at the bottom of the nut and is fixedly mounted in the blind hole. A non-return assembly is further arranged at the bottom of the second check washer. Compared with the prior art, the check bolt assembly is simple in structure and reasonable in design, stability and reliability of bolt connection can be guaranteed for a long time, the influenceof vibration on bolt connection can be reduced, and the check bolt assembly is worthy of popularization.
