Technical Field
The utility model relates to a nut technical field specifically is a novel lock nut of combination.
Background
The nut isNut capAnd is andboltOrScrew rodParts screwed together for fastening purposes, all the elements necessary for manufacturing machines being divided into different groups according to the materialCarbon steelStainless steel, non-ferrous metals (such as copper), and the like. The nut being a part for the tight connection of mechanical equipment, through the insideScrew threadThe same specification nuts and bolts can be connected together, for example, the nuts of M4-P0.7 can only be connected with M4-A P0.7 series bolt (in the nut, M4 means that the inner diameter of the nut is about 4mm, and 0.7 means that the distance between two screw threads is 0.7 mm); also, for aesthetic products, nuts such as 1/4-20 can only fit screws 1/4-20 (1/4 means that the inner diameter of the nut is about 0.25 inch, and 20 means that there are 20 teeth per inch). The working principle of the nut is that the nut is adoptedBoltThe friction between them is self-locking. But the reliability of such self-locking is reduced in dynamic loads. In some important occasions, some anti-loosening measures can be taken to ensure the locking reliability of the nut. One of the anti-loosening measures is the locking nut.
The convex lock nut and the concave locknut of the existing nut are not tight enough when being connected, the anti-loosening effect is poor, and the nut is easy to loosen and fall off when being subjected to high-speed vibration, so that a novel combined novel locknut is urgently needed to be developed.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a novel lock nut of combination to the protruding lock nut and the concave lock nut of the nut that proposes in solving above-mentioned background are inseparable enough when being connected, and locking effect is relatively poor, easily causes the nut not hard up scheduling problem that drops when receiving high-speed vibrations.
In order to achieve the above object, the utility model provides a following technical scheme: the utility model provides a novel lock nut of combination, includes the bolt main part, install the mounting in the bolt main part, the mounting top is provided with protruding lock nut, protruding lock nut's upper end is provided with protruding portion that closes, and protruding lock nut closely revolves through protruding portion and concave lock nut and connects, and concave lock nut is inside to be provided with concave portion that closes.
Preferably, the surface of the convex combination part is provided with four groups of grooves.
Preferably, the centers of the surfaces of the male locking nut and the female anti-loose nut are provided with slotted holes.
Preferably, the bolt body extends through the male locknut to the exterior of the female locknut.
Preferably, the convex part and the concave part are tightly embedded.
Preferably, the convex part is of a cylindrical structure, and the concave part is of a conical structure.
Compared with the prior art, the beneficial effects of the utility model are that:
the utility model discloses screw up on bolted connection spare with protruding lock nut earlier, screw up on the bolt with concave lock nut afterwards, make protruding portion of closing coincide each other with concave portion of closing, because concave nut is the toper structure, in screwing up the in-process, four fritters that protruding portion of closing of convex nut was cut apart by the recess take place to be out of shape, four inside lines of teeth of fritter and bolt lines of teeth are held tightly, it is better to make columniform protruding portion of closing sticiss the degree of coincidence under conical concave portion of closing, protruding portion cylindrical material resilience that closes simultaneously is good, make the concave lock nut of cone exert better locking effect, the utility model discloses possess the installation simultaneously and dismantle convenient and fast, can carry out used repeatedly, be applicable to on the great equipment of vibrations, play better locking effect.

Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments.
Referring to fig. 1-8, the present invention provides an embodiment: the utility model provides a novel lock nut of combination, includes bolt main part 5, installs mounting 2 on the bolt main part 5, and 2 tops of mounting are provided with protruding lock nut 4, and the upper end of protruding lock nut 4 is provided with protruding portion 7, and protruding lock nut 4 closely connects soon through protruding portion 7 and concave lock nut 1, and concave portion 8 is provided with to concave lock nut 1 inside.
Further, the surface of the convex part 7 is provided with four groups of grooves 3, and the grooves 3 are provided with four groups.
Furthermore, the centers of the surfaces of the convex lock nut 4 and the concave locknut 1 are both provided with slotted holes 6.
Further, bolt main part 5 passes protruding lock nut 4 and extends to concave locknut 1 outside for protruding lock nut 4 is inseparabler with concave locknut 1 interlock, and the nut condition of coming off or moving back the pine can not appear during the use, has improved the fastening effect when nut is connected with bolt main part 5.
Further, the male portion 7 and the female portion 8 are tightly fitted to each other.
Further, protruding portion 7 that closes is cylindrical structure, concave portion 8 that closes is the cone structure, because concave locknut 1 is inside to be the toper structure, at the tightening in-process, protruding portion 7 of protruding lock nut 4 is taken place to be out of shape by four fritters that recess 3 was cut apart, four inside insections of fritter and 5 insections of bolt main part are held tightly, it is better to make the columniform protruding portion 7 sticis agreed with the degree under conical concave portion 8 sticiss, protruding portion 7 cylindrical material resilience of portion of closing is good simultaneously, make the concave locknut 1 of cone exert better locking effect.
The working principle is as follows: when in use, the fixing piece 2 is arranged on the bolt main body 5, the convex lock nut 4 is arranged above the fixing piece 2, the upper end of the convex lock nut 4 is provided with the convex part 7, the convex lock nut 4 is tightly screwed with the concave anti-loose nut 1 through the convex part 7, the concave part 8 is arranged in the concave anti-loose nut 1, the convex part 7 is in a cylindrical structure, the concave part 8 is in a cone structure, the convex lock nut 4 is firstly screwed on the bolt main body 5 and then the concave anti-loose nut 1 is screwed on the bolt, so that the convex part 7 is matched with the concave part 8, because the concave anti-loose nut 1 is in a cone structure, four small blocks of the convex part 7 of the convex lock nut 4 divided by the groove 3 deform in the screwing process, the internal threads of the four small blocks are tightly held with the threads of the bolt main body 5, and the matching degree of the cylindrical convex part 7 under the conical concave part 8 is better, meanwhile, the convex part 7 is made of cylindrical materials, so that the conical concave locknut 1 has a better locking effect.
