As a kind of preferred version of the present utility model, the side of described screw-in fixed cover is formed with the screw-in tooth be meshed with tapped hole.
As a kind of preferred version of the present utility model, described guide groove is longitudinally highly for screwing in the height sum of fixed cover and screw rod fixing device.
As a kind of preferred version of the present utility model, the distance of described semicircle nut width direction is less than 1/2 of length direction distance.
As a kind of preferred version of the present utility model, described two semicircle nut equal and opposite in directions and symmetrical.
As a kind of preferred version of the present utility model, described guide groove cross section is step-like structure.
The beneficial effects of the utility model are: the half of nut clamping screw rod arranging two movable connections, nut is screwed under the effect of holddown spring by interior hexagonal, to the opposing compression of two half of nuts, and then fastening screw, two half of nut upper end screw-in fixed covers are fixedly connected with, and can be fixed with fastening for the screw rod of different-diameter, this programme structure is simple, easy for installation, improve the machining accuracy of product, also ensure that aesthetic appearance and the quality of product of nut surface.
Accompanying drawing explanation
Fig. 1 is a kind of self adaption adjustable nut of the utility model structural representation.
Fig. 2 is the installation diagram of a kind of self adaption adjustable nut of the utility model.
Reference character in figure: screw in fixed cover 1, advances through hole 1-1, screw rod fixing device 2, semicircle nut 2-1, nut fixing body 3, holddown spring 4, interior hexagonal screws in nut 5, guide groove 6, through hole 7, tapped hole 8.
Embodiment
Below in conjunction with accompanying drawing, the utility model embodiment is elaborated.
Embodiment:
As depicted in figs. 1 and 2: a kind of self adaption adjustable nut, nut fixing body 3 and screw rod fixing device 2 is comprised; The tapped hole 8 of accommodation and fastening screw is provided with in this nut fixing body 3; The guide groove 6 for holding screw rod fixing device 2 is formed in tapped hole 8; This guide groove 6 cross section is step-like structure; The dual-side of this nut fixing body 3 is formed with the through hole 7 slided for holddown spring 4, is provided with hexagonal in being rotatably connected with through hole 7 and screws in nut 5 in this through hole 7; This screw rod fixing device 2 upper end is provided with the screw-in fixed cover 1 for fixing this screw rod fixing device 2; The centre of this screw-in fixed cover 1 is formed with the advances through hole 1-1 matched with tapped hole 8; This screw rod fixing device 2 is two semicircle nut 2-1 matched; Interior hexagonal screws in nut 5 and screws in nut fixing body 3 by through hole 7, and this semicircle nut 2-1 is under the extruding of holddown spring 4, and the length direction transverse shifting along guide groove 6 carrys out fastening screw, and the internal diameter of this screw rod fixing device 2 is less than the internal diameter of tapped hole 8; The bottom of this through hole 7 is higher than the attachment face of guide groove 6.
Be convenient to fastening screw fixing device 2, the side screwing in fixed cover 1 is formed with the screw-in tooth be meshed with tapped hole 8, and be meshed with the tapped hole 8 in nut fixing body 3 by screwing in fixed cover 1, screw rod fixing device 2 is limited in nut fixing body 3; In addition also in order to aesthetic appearance and the quality of product on nut fixing body 3 surface, guide groove 6 is longitudinally highly for screwing in the height sum of fixed cover 1 and screw rod fixing device 2, like this when screwing in fixed cover 1 and being screwed in nut fixing body 3, the upper surface of this screw-in fixed cover 1 and the upper surface of nut fixing body 3 are in same level.
Equally, in order to the screw rod that more fastening nonstandard screws or some diameter differ, the distance of this semicircle nut 2-1 width direction is less than 1/2, two semicircle nut 2-1 equal and opposite in directions of length direction distance and symmetrical.
Working principle of the present utility model: the half of nut 2-1 of two couplings is contained in the guide groove 6 in nut fixing body 3, as shown in Figure 1, puts into holddown spring 4 in left and right, screws in nut 5 fixed position by interior hexagonal, and adjusts impacting force size.When interior hexagonal being screwed in nut 5 entirety and screwing in this nut fixing body 3, screw size is changeable, because holddown spring 4 acts on, two half of nut 2-1 of coupling can have minute movement according to screw-in power size, nut can be finely tuned in allowed band, the large I of nut screw-in power compresses holddown spring 4 extending amount by interior hexagonal screw-in nut 5 and controls, and ensures that nut correctly screws in screw rod.This screw-in fixed cover 1 is fixed on the half of nut 2-1 of two couplings in nut fixing body 3.
To the above-mentioned explanation of the disclosed embodiments, professional and technical personnel in the field are realized or uses the utility model.To be apparent for those skilled in the art to the multiple amendment of these embodiments, General Principle as defined herein when not departing from spirit or scope of the present utility model, can realize in other embodiments.Therefore, the utility model can not be restricted to these embodiments shown in this article, but will meet the widest scope consistent with principle disclosed herein and features of novelty.
Although more employ reference character in figure herein: screw in fixed cover 1, advances through hole 1-1, screw rod fixing device 2, semicircle nut 2-1, nut fixing body 3, holddown spring 4, interior hexagonal screws in nut 5, guide groove 6, through hole 7, term such as tapped hole 8 grade, but do not get rid of the possibility using other term.These terms are used to be only used to describe and explain essence of the present utility model more easily; The restriction that they are construed to any one additional is all contrary with the utility model spirit.
