Problems solved by technology

Although this method does not require additional components other than the bolt and the locking piece, it will fail when the bolt and the locking piece are slightly loose and the sawtooth structure cannot be tightly against the part.
[0005] On the other hand, when the multiple parts are affected by external forces, resulting in excessive load on the bolt and the lock, the local stress of the thread of the bolt may increase, and the thread may collapse, which is called collapse. tooth

Abstract

The invention discloses a bolt, which comprises a body, a head and a threaded part. The body has a central axis. The head is arranged at one end of the body. The threaded portion spirally surrounds and connects to the body along the central axis. The threaded part has a bearing surface facing the head. The load-bearing surface is a surface with a continuous slope or an inflection point. The load-bearing surface includes a concave curved surface, a convex curved surface and a load-bearing tooth ventral surface. The concave curved surface touches the body, and the convex curved surface is farther away from the body than the concave curved surface. One side of the convex curved surface is connected to the concave curved surface and the other side of the convex curved surface is connected to the load-bearing tooth ventral surface .

Description

Technical field [0001] The present invention relates to a bolt, and more particularly to a bolt of anti-loose and anti-disabling. Background technique [0002] When multiple parts are combined in the mechanical domain, it is often fixed using a bolt with a bolt with a mother-threaded pair (such as a nut). The bolts are brought into the head of the bolt closest to the head of the bolt by the bolts, and then lock the bolt lock in the plurality of parts. The locking is fixed to the head of the bolt and the locking member is fixed to the lock. [0003] Such a fixed manner occurs when the plurality of parts are vibrating, may result in loose discharging between the bolts and the lock, thereby causing the plurality of parts to be loose from each other. In order to avoid the case where the bolts are loose, the relevant fields have developed additional components to prevent bolts from loose-locking. For example, an element such as a spring washer such as a bolt is added or between the lo...
