Embodiment Construction

[0011] For anti-loosening anti-loosening bolts, when in use, screw in the standard nut 2 first, then screw in the anti-tightening nut 1 in the reverse direction after tightening the member, so that the nut 1 and the nut 2 are closely attached. Since the inner cavity of the buckle nut 1 is limited, it is necessary to confirm the exact thickness of the connected components when selecting the bolt length.

Abstract

The invention discloses a check bolt with left-handed threads, which comprises a nut (1) with left-handed threads, a standard nut (2) and a screw stem (3). Reverse threads are arranged at one end of the screw stem (3). After being screwed down by the standard nut (2), a component is screwed down by the nut with the left-handed threads, the nut (1) is closely attached to the nut (2), accordingly, if the nut (2) is loosened, the nut (2) can drive the nut (1) to rotate in the same direction, the direction is the screw-in direction of the nut (1) with left-handed threads, accordingly, loosening of the nut (2) is prevented, and the purpose of preventing the bolt from being loosened is achieved.

Description

[technical field] [0001] The invention relates to a bolt, especially an anti-loosening bolt. [Background technique] [0002] Most of the existing standard bolts use double nuts to achieve anti-loosening. Although this method can achieve a certain anti-loosening effect, because the two nuts rotate in the same direction, they sometimes rotate at the same time, which cannot ensure anti-loosening. the goal of. [Content of the invention] [0003] The object of the present invention is to provide an anti-loosening bolt that ensures the anti-loosening effect. [0004] In order to achieve the above purpose, the anti-loosening anti-loosening bolt of the present invention is composed of an anti-tightening nut 1, a standard nut 2 and a screw rod 3, and a section of reverse thread is provided on the end of the bolt rod. Tighten the standard nut 2 to the member and then reversely tighten the anti-tightening nut 1, so that the nut 1 and the nut 2 are closely attached. In this way, if ...
