Detailed Description
Example one
In this embodiment, as a basic structure of the locknut assembly, as shown in fig. 1, a nut assembly is composed of a bolt 3 and a set of nuts matched with the bolt, the nut set includes a conventional nut 2 sleeved on the bolt 3 and a locknut 1 sleeved on the bolt 3 and closely attached to the conventional nut 2, the locknut 1 has an upper end surface 1-1 deviating from a contact surface of the conventional nut 2 and a lower end surface 1-2 close to the contact surface of the conventional nut, and the lower end surface 1-2 is an inclined surface which is not perpendicular to a thread axis. The inclined surface and the end surface of the conventional nut form an included angle before being screwed.
The lower end face 1-2 inclined is formed in the cold heading die and then tapped, and the processing technology is the same as that of a conventional nut, and the processing is convenient and low in cost.
During the use, bolt 3 receives opposite direction's transverse force on the right side of conventional nut and locknut's left side, and bolt 3 upper portion receives extra side square T, realizes the chucking bolt, makes the bolt tail section produce certain elastic deformation, forms certain contained angle with main screw thread section, reaches locking purpose.
Example two
The structure and the processing technology of the present embodiment are substantially the same as those of the first embodiment, as shown in fig. 2, except that: the lower end surface 1-2 of the locknut is provided with a section of unthreaded hole 1-3 with the diameter larger than the diameter of the thread of the locknut, and the lower end surface of the unthreaded hole is an inclined surface. Compared with the first embodiment, the tail section of the bolt and the main thread section can form a larger included angle, and the anti-loosening effect is further improved.
EXAMPLE III
The structure and processing technique of the present embodiment are substantially the same as those of the first embodiment, as shown in fig. 3, except that: the end face of the contact surface of the conventional nut 2 and the anti-lock nut is provided with a unthreaded hole 2-1 with the diameter larger than the diameter of the thread of the conventional nut. Compared with the embodiment, the bolt tail section and the main thread section can form a larger included angle, and the anti-loosening effect is further improved.
Example four
The structure and processing technique of this embodiment are substantially the same as those of the first embodiment, as shown in fig. 4, except that: the lower end surface 1-2 of the locknut 1 is provided with a circumferential anti-skid groove 1-4.
EXAMPLE five
The structure and processing technique of the present embodiment are substantially the same as those of the first embodiment, as shown in fig. 5, except that: the upper end surface of the conventional nut 2 is provided with a circumferential anti-slip groove 2-2.
The nut set of the above embodiment may employ various threads as in the prior art.
In addition to the above embodiments, the present invention may have other embodiments. All the technical solutions formed by adopting equivalent substitutions or equivalent transformations fall within the protection scope claimed by the present invention.
Claims (4)
1. The utility model provides a nut component, includes a set of nut that matches with the bolt, its characterized in that: the set of nuts comprises nuts sleeved on the bolts and locknuts sleeved on the bolts and tightly attached to the nuts, the locknuts are provided with upper end faces deviated from the nut contact faces and lower end faces close to the nut contact faces, the lower end faces are inclined planes which are not perpendicular to the axis of the threads, included angles are formed between the lower end faces of the locknuts and the nut end faces before screwing, and one end, close to the lower end face, of each threaded hole of each locknut is provided with a unthreaded hole, the diameter of each unthreaded hole is larger than the diameter of each threaded hole.
