Embodiment Construction
[0038] For the sake of simplicity, split processing is used in this embodiment. Take M16 bolts and nuts as an example.
[0039] Process the round table with internal thread, the internal thread of the round table is M17X2. The diameter of the top surface of the round table is 21 mm, and the diameter of the bottom surface of the round table is 24 mm. The height of the round platform is 10mm. The round platform and the internal thread share an axis.
[0040] Process the concave nut, the diameter of the top surface of the concave round table is 19.68mm, and the diameter of the bottom surface is 23mm. The height of the concave table is 11mm. The internal thread is the standard thread of M16X2. The height of the internal thread part is 10mm. The concave round platform and the internal thread share an axis.
[0041] Put the fastener on the screw, and screw on the standard M16 hex nut. Twist until it cannot be twisted by hand.
[0042] Screw the machined round table onto the...

The invention belongs to the field of fasteners, and relates to an anti-loosening combined nut. It includes a male nut and a female nut, and the protruding part of the male nut contacts and fits with the concave part of the female nut. Features: The internal thread of the convex nut consists of two parts: the internal thread 7 of the hexagonal part of the convex nut and the internal thread 8 of the protruding part. The internal thread 7 is a standard internal thread, and the internal thread 8 is a non-standard thread. There is a special relative position between the thread 7 and the thread 8 . The protruding part of the convex nut is an elliptical platform 4, or a combination of an elliptical column and an elliptical platform. The internal thread 7, the internal thread 8, and the elliptical platform 4 share an axis. The recessed portion of the concave nut is a concave round platform 9 . The internal thread of the concave nut is a standard internal thread. The internal thread of the concave nut shares an axis with the concave part. The protruding part on the protruding nut is provided with a longitudinal groove 5 along the axial direction, and the protruding nut is provided with an annular discontinuous groove 6 at the bottom of the protruding part.
Description
Technical field: [0001] The invention belongs to the field of fasteners, in particular to an anti-loosening combined nut. Background technique: [0002] For threaded connection, in order to realize the smooth screwing of the thread, there must be a gap between the internal and external threads. This determines that under complex working conditions, the pressing force between the threads will become smaller or disappear. This causes the nut to loosen. [0003] For threaded connection, the nut in contact with the fastener is not only subject to axial force, but also the lateral force exerted by the fastener in contact with it, and even the lateral force at each point of the contact surface is uneven. In this way, a rotating force may be generated on the nut in contact with the fastened part. If the direction is the same as the loosening and the force is large enough, the nut loosening is inevitable. [0004] In order to solve the loosening of fasteners, methods such as spr...
