Problems solved by technology

[0003] However, the double nut anti-loosening method is not absolutely stable. When the shock and vibration loads are applied, the friction between the nut and the workpiece may be reduced or even disappear, especially in some high-frequency and high-amplitude vibration environments. The anti-loosening structure will still come loose

Embodiment

[0018] Example: see figure 1 , figure 2 , image 3 and Figure 4 , an anti-loosening fastener assembly, including a bolt 6 and a nut that cooperates with the bolt 6 to limit the workpiece 7, and the number of nuts that cooperate with the bolt 6 on the same side as the workpiece 7 is at least two, including the nut that cooperates with the workpiece 7 The lower nut 2 that is in contact with the upper nut 3 that limits the position of the lower nut 2 is provided with a positioning cap 1 that limits the position of the lower nut 2 between the two nuts, and the positioning cap 1 is set on the lower nut 2 Above, the positioning cap 1 includes a cap 11 matched with a corresponding nut, and a bent buckle connected to the cap 11 for buckling the edge of the workpiece 7 .

[0019] As a preference, the cap 11 is open at one end and closed at the other end, and the internal shape of the opening matches the shape and size of the restricted lower nut 2, and the middle part of the close...

Abstract

The invention provides an anti-loosening fastener component which comprises a bolt and at least two nuts. The nuts are matched with the bolt to limit a workpiece. The nuts is matched with bolts relative to the same side of the workpiece. The nuts includes a lower nut in contact with the workpiece and an upper nut limiting the lower nut. A positioning nut fastener limiting the lower nut is disposed between the two nuts. The positioning nut fastener sleeves the lower nut. The positioning nut fastener comprises a nut cap matched with the corresponding nut and a bent fastener which is connected to the nut cap and used for fastening the edge of the workpiece. The nut cap of the positioning nut fastener sleeves the lower nut matched with the nut cap in size, the short arm of the bent fastener fastens the edge of the corresponding workpiece, and accordingly the nut fastener limit loosening of the lower nut like a fixing wrench. A screw can penetrate a limit hole to be fixed on the workpiece if necessary, the fastened lower nut can be further limited, and loosening can be prevented effectively.

Description

technical field [0001] The invention relates to the field of bolt fixing devices, in particular to an anti-loosening fastener assembly. Background technique [0002] Threaded connection is a detachable connection made of threaded parts. It has a simple structure and is easy to assemble and disassemble. It is widely used in various mechanical equipment. However, under the action of shock, vibration or variable load, or under the condition of high temperature or large temperature change, the pretightening force and friction force in the threaded connection will gradually decrease or may disappear instantaneously, resulting in failure of the connection. Once the threaded connection fails, it will seriously affect the normal operation of the machine and even cause accidents. Therefore, in the design and production process of mechanical products, nut locking mechanisms are often used to ensure safe and reliable connections. The most common nut locking mechanism is two shaft nut...
