Abstract
The utility model discloses a nut which comprises a nut body (1) and an annular protection sleeve (2) integrated with the nut body (1) into a whole; an internal thread (3) is arranged on the inner wall of the annular protection sleeve (2); and the axial length of the annular protection sleeve (2) is more than the axial thickness of the nut body (1). The nut has the advantages that: the connected parts are prevented from having dislocation friction.
Description
Technical field:
The utility model relates to a kind of threaded connector, specifically is a kind of nut.
Background technique:
Nut is a kind of part that machinery closely can be coupled together, it usually and bolt be used the purpose that reaches fastening component, promptly be connected the through hole that component are provided with, come to carry out fastening component the other end attaching nut of bolt by bolt is penetrated.Owing to above-mentionedly be connected the external diameter that through hole internal diameter that component are provided with all can be slightly larger than the bolt screw rod usually, therefore, connected component issue the looks friction that misplaces mutually through regular meeting in vibration, thereby cause certain wearing and tearing to being connected component.In order to address this problem, disclosed name is called the utility model patent of " a kind of nut " on the State Intellectual Property Office website, this model utility is because the interior edge face of nut is provided with one is holistic ring jacket with nut, therefore, it can prevent to be connected component and issue misplace the mutually phenomenon of friction of looks in vibration by ring jacket being inserted be arranged in the through hole that be connected on the component.Yet because the axial length of described ring jacket is less than the axial thickness of nut, therefore, it is not very desirable to preventing to be connected the effect that the dislocation friction takes place between the component.
In addition, though be connected the external diameter of the internal diameter of component through hole greater than the bolt screw rod,, the space that this difference promptly is connected between component through-hole wall and the bolt screw rod outer wall is generally all smaller, therefore, the process in the ring jacket insertion connected component through hole generally all comparatively bothers.
The model utility content:
The technical problems to be solved in the utility model is to provide a kind of and can prevent to be connected the nut that the dislocation friction takes place between the component better.
Technical solution of the present utility model is that a kind of nut with following structure is provided: it comprise nut body and with nut body be holistic ring jacket; The inwall of described ring jacket is provided with internal thread; The axial length of described ring jacket is greater than the axial thickness of described nut body.
After adopting above structure, compared with prior art, the utlity model has following advantage: since in the utility model the axial length of said ring jacket greater than the axial thickness of described nut body, in other words, ring jacket and the surface of contact that is connected between the component through-hole wall increase greatly in the utility model, therefore, the utility model can prevent from better to be connected the dislocation friction takes place between the component, thereby effectively avoids being connected parts wear.
As a kind of improvement of the present utility model, can establish chamfering I between the end face that described ring jacket is not connected with nut body and the outer circumferential walls of ring jacket.The insertion of ring jacket is convenient in the setting of chamfering I, thereby has brought convenience for the installation of nut.
As another kind of improvement the of the present utility model, can establish chamfering II between the end face that described ring jacket is not connected with nut body and the circumferential inner wall of ring jacket.The setting of chamfering II can be so that the bolt screw rod inserts the endoporus that is connected to ring jacket.
Description of drawings:
Fig. 1 is the structural representation of the utility model nut.
Fig. 2 be Fig. 1 partly cut open structural representation.
Shown in the figure, 1, nut body, 2, ring jacket, 3, internal thread, 4, chamfering II, 5, chamfering I.
Specific embodiment:
The utility model is described in further detail below in conjunction with the drawings and specific embodiments:
As depicted in figs. 1 and 2, in this specific embodiment, the utility model nut comprises nut body 1 and ring jacket 2; Described ring jacket 2 is an integral body with nut body 1; The inwall of described ring jacket 2 is provided with internal thread 3; The direction of described internal thread 3 is consistent with internal thread direction on the nut body 2; The axial length of described ring jacket 2 is greater than the axial thickness of described nut body 1; Be provided with chamfering I 5 between the end face that described ring jacket 2 is not connected with nut body 1 and the outer circumferential walls of ring jacket 2; Be provided with chamfering II 4 between the end face that described ring jacket 2 is not connected with nut body 1 and the circumferential inner wall of ring jacket 2.
It is described that the utility model is not limited to the foregoing description, and it also allows following variation, as chamfering I 5 only is set, or chamfering II 4 only is set, or chamfering I 5 and chamfering II 4 be not provided with, more than these change and all fall into protection domain of the present utility model.
Claims (3)
1, a kind of nut, it comprise nut body (1) and with nut body (1) be holistic ring jacket (2); The inwall of described ring jacket (2) is provided with internal thread (3), it is characterized in that: the axial length of described ring jacket (2) is greater than the axial thickness of described nut body (1).
2, nut according to claim 1 is characterized in that: be provided with chamfering I (5) between the end face that described ring jacket (2) is not connected with nut body (1) and the outer circumferential walls of ring jacket (2).
