Embodiment Construction

[0016] It should be noted that, in the case of no conflict, the embodiments of the present invention and the features in the embodiments can be combined with each other.

[0017] The present invention will be described in detail below with reference to the accompanying drawings and examples.

[0018] The radial lock locknut of the present invention, such as Figures 1 to 3 As shown, it includes a nut body 1, and one end of the nut body 1 extends outward to form an extension body 2. A threaded hole that passes through the nut body 1 and the extension body 2 and matches the screw rod is provided coaxially, and the upper edge of the side wall of the extension body 2 A number of side ports 7 are evenly distributed in the axial direction, and external threads are arranged on the outer wall of the extension body 2;

[0019] Also comprises lock nut 3, is provided with coaxial stepped through hole on the lock nut 3, and step shape through hole comprises the locking screw hole 4 with ...

Abstract

The invention provides a radial locking locknut. The radial locking locknut comprises a nut body and an extension body, wherein threaded holes are formed in the nut body and the extension body; a plurality of side openings are uniformly formed in the side wall of the extension body; an external thread is arranged on the outer side wall of the extension body; a locknut body is further included; thelocknut is provided with coaxial step-shaped through holes; the step-shaped through holes comprise locking screw holes with small aperture and locking optical holes with large aperture; locking ringsare fixedly arranged in the circumferential direction on the inner wall, close to the end face, of each locking optical hole; locking rings provide with a plurality of taper-shaped through holes; andthe inner diameter of the locking rings are gradually increased from small to large towards the locking screw holes in the direction of the locking optical holes. When the radial locking locknut is in use, the locknut body is screwed on the extension body, the locking rings perform a pressing force and a tightening force on the extension body, and the side opening on the extension body is forcedto contract inwardly, so that the threads between the extension body and a screw are pressed, the friction between the threads is strengthened instead of disappearing, and the purpose of locking a fastener without looseness is achieved.

Description

technical field [0001] The invention relates to the field of mechanical equipment fasteners, in particular to a radial locking locknut. Background technique [0002] The assembly process of mechanical equipment from parts to complete machine is inseparable from the close fit of fasteners. Bolt fasteners are the most widely used form of fasteners. In various links such as equipment transportation and operation, due to the influence of external forces such as vibration, bolt fasteners will be instantly damaged due to the pressure between the interlocking threads. The disappearance makes the friction between the threads zero, so that the threaded connection becomes loose or even falls off, which affects the normal performance of the equipment and even causes the equipment to fail. Therefore, the anti-loosening and anti-loosening of bolt fasteners has always been a technical problem that practitioners in the field need to solve urgently. [0003] In order to take advantage of ...
