Abstract

The utility model discloses a kind of self-locking round nuts, including round nut ontology, it is characterized by: the side wall of the round nut ontology offers self-locking grooves, the inner wall that the self-locking grooves extend to round nut ontology forms self-locking notch, and the internal screw thread of round nut ontology is locally truncated the self-locking notch, the position that the round nut ontology corresponds to self-locking grooves is offered the perforative self-locking hole of self-locking grooves, the screw being threadedly engaged therewith is inserted in the self-locking hole, when screw is lock onto self-locking hole, the screw thread of screw periphery is partially located at self-locking notch.The utility model has the following advantages that and effect: solving the problems, such as that round nut is easy to appear loosening in large-diameter.

Description

A kind of self-locking round nut
Technical field
The utility model relates to nut technical field, in particular to a kind of self-locking round nut.
Background technique
Under normal circumstances, round nut often with stop washer adapted, by the slot in washer on tongue insertion axis when assembly, and incite somebody to action In the slot of the outer tongue insertion round nut of washer, nut is locked, the axis of axial restraint or agitating shaft frequently as rolling bearing To positioning.When the axially position for agitating shaft, and when the diameter of axle is larger, because active force is larger, the round nut stop of institute's adapted Still round nut can not be fixed when washer, be easy to be exited by tear fracture so that round nut slowly loosens.
Utility model content
The purpose of the utility model is to provide a kind of round nuts that can be self-locking, solve round nut and are easy in large-diameter The problem of now loosening.
The above-mentioned technical purpose of the utility model has the technical scheme that a kind of self-locking circle spiral shell Mother, including round nut ontology, it is characterised in that: the side wall of the round nut ontology offers self-locking grooves, the self-locking grooves The inner wall for extending to round nut ontology forms self-locking notch, and the internal screw thread of round nut ontology is locally truncated the self-locking notch, The position that the round nut ontology corresponds to self-locking grooves is offered the perforative self-locking hole of self-locking grooves, is plugged in the self-locking hole There is the screw being threadedly engaged therewith, when screw is lock onto self-locking hole, the screw thread of screw periphery is partially located at self-locking notch.
By using above-mentioned technical proposal, after tightening screw, the screw thread of screw periphery is partially located at self-locking notch and compensates The internal screw thread that round nut ontology is truncated, and then change the local screw pitch of round nut ontology, self-locking grooves narrow, and have its own Self-locking function, next the phenomenon that being just not in loosening on such round nut ontology, to solve round nut ontology big The problem of loosening is easy to appear when the diameter of axle.Its structure is simple, is easy dismounting, and the later period can replace screw, have locking self-locking The advantages of good reliability.
Be further arranged to: the self-locking hole to open up direction parallel with the inner wall of round nut ontology.
By using above-mentioned technical proposal, self-locking stability is improved, avoids next on screw, the screw thread and circle of screw periphery The internal screw thread positional shift of nut body, causes self-locking effect bad or even can not be self-locking.Meanwhile it being also avoided that due to screw position The hidden danger that offset causes its periphery screw thread easy to wear is set, the service life of screw is extended.
Be further arranged to: the self-locking hole along a part that screw protrudes into direction is through-hole, another part is screw thread Hole.
By using above-mentioned technical proposal, facilitate the insertion of screw, screw need to be only aligned to self-locking hole insertion, avoided Need matching thread precession from the beginning, when screw be inserted into self-locking hole after be threadedly engaged again with threaded hole, have it is convenient and strength-saving, Assemble quick advantage.
Be further arranged to: the self-locking grooves extend to inner wall from the outer wall of round nut ontology.
By using above-mentioned technical proposal, slot from the outer wall inward wall of round nut ontology, without in round nut Interior carries out grooving operations, easy to operate, reduces fluting cost, and can improve qualification rate and production efficiency.
Be further arranged to: the shape of the self-locking grooves is arc.
It is circular actual conditions in conjunction with screw and round nut ontology by using above-mentioned technical proposal, is meeting certainly While bolt part, reduce the area of self-locking grooves, guarantee round nut ontology be not easy it is excessive by self-locking groove area and in the generation The phenomenon that damage.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of embodiment;
Fig. 2 is the side view of embodiment;
Fig. 3 is the cross-sectional view of embodiment.
In figure: 1, round nut ontology;2, self-locking grooves;21, self-locking notch;3, self-locking hole;4, screw.
Specific embodiment
The utility model is described in further detail below in conjunction with attached drawing.
Referring to figs. 1 to Fig. 3, a kind of self-locking round nut, including round nut ontology 1, the side wall of round nut ontology 1 offer Lateral self-locking grooves 2, the inner wall that self-locking grooves 2 extend to round nut ontology 1 forms self-locking notch 21, and the self-locking notch 21 will be justified The internal screw thread of nut body 1 is locally truncated, and the position of the corresponding self-locking grooves 2 of round nut ontology 1 offers self-locking grooves 2 are perforative certainly Lockhole 3 is inserted with the screw 4 being threadedly engaged therewith in self-locking hole 3, when screw 4 is lock onto self-locking hole 3,4 periphery of screw Screw thread is partially located at self-locking notch 21.
Wherein, self-locking hole 3 opens up that direction is parallel with the inner wall of round nut ontology 1, and self-locking grooves 2 open up direction and circle The inner wall of nut body 1 is perpendicular.
Wherein, self-locking hole 3 along a part that screw 4 protrudes into direction is through-hole, another part is threaded hole, without will be entire Self-locking hole 3 is designed as screw thread, can reduce production cost.
In addition, self-locking grooves 2 extend to inner wall from the outer wall of round nut ontology 1, and the self-locking grooves 2 are circumferentially formed along cell wall Half arc.
This specific embodiment is only the explanation to the utility model, is not limitations of the present invention, ability Field technique personnel can according to need the modification that not creative contribution is made to the present embodiment after reading this specification, but As long as all by the protection of Patent Law in the scope of the claims of the utility model.
