Description
Technical field
The utility model relates to fastener areas, be specifically related to a kind of can the bolt and nut component of axial stretching.
Background technique
The bolt and nut component be made up of bolt body, nut body and packing ring is a kind of conventional fastener assembly, but in the occasion that some shake, after nut body coordinates with bolt body, often easily occurs the phenomenon got loose, thus easily affects the reliable operation of equipment.Meanwhile, because existing bolt body all cannot carry out axial stretching, therefore when above-mentioned bolt and nut component is used to fastening different product, often need different length specifications, thus cause bolt and nut component of a great variety, lack versatility.
Summary of the invention
For the deficiencies in the prior art, the utility model provides a kind ofly not only had had good anti-loosing effect simultaneously but also can the bolt and nut component of axial stretching.
For achieving the above object, the utility model provide a kind of can the bolt and nut component of axial stretching, include bolt body, nut body and packing ring, described bolt body includes screw rod and nut, one end of described nut is provided with connecting sleeve, described connecting sleeve is linearly evenly equipped with multiple draw-in groove along its axial direction, described screw rod is provided with the axial extending end penetrated in described connecting sleeve, and described axial extending end is made up of some circumferentially uniform contiguous blocks, the axial outer end portion of described contiguous block is provided with and can forms with corresponding draw-in groove the barb connected and fixed, described nut body and packing ring are all set on screw rod, and described packing ring correspondence is positioned at the axially inner side of nut body, on nut body, correspondence offers the screw coordinated with described screw rod bolt, the axial inner ends of described nut body is also provided with the reaming that and diameter coaxial with described screw is greater than described screw, cyclic spring wear-resisting ring is equiped with in described reaming, and the axial outer end face of described cyclic spring wear-resisting ring is provided with two extended legs, an oval cavity is formed between two extended legs, annular ring is equiped with in described oval cavity, it is the annular protrusion of reversed V-shape that described packing ring is provided with a cross section on the axial inner ends face of nut body, and the V-arrangement tip of described annular protrusion penetrates in described oval cavity, and abut with annular ring, two extended leg ends on cyclic spring wear-resisting ring are resisted against on the bi-side, V-arrangement tip of annular protrusion respectively, the axial outer end face of described packing ring nut body is dorsad evenly distributed in multiple non-slip bumps, the outer circumferential face of described nut body offers the anti-skidding lines groove be inclined to set.
The beneficial effects of the utility model are: adopt said structure, by the draw-in groove card of diverse location on the contiguous block barb on screw rod and connecting sleeve is joined, the axial stretching of bolt body can be realized, thus make bolt and nut component provided by the utility model can be used to the product of fastening various different length, there is good versatility.Simultaneously, when above-mentioned nut body and packing ring with bolt body lock assemble time, the axial outer end kept man of a noblewoman of described packing ring nut body dorsad first can abut with the product formation be fixed, thus impel the V-arrangement tip of the reversed V-shape annular protrusion be positioned on packing ring axial inner ends face inwardly to extrude annular ring, annular ring axially will move inward along oval cavity, and in the process of movement, impel two extended leg radially outwards on described cyclic spring wear-resisting ring to move, thus make the screw rod of described extended leg and bolt body form frictional fit, effectively prevent nut body from occurring the phenomenon that gets loose after mounting.In addition, the axial outer end face due to described packing ring nut body dorsad is also evenly distributed in multiple non-slip bumps, therefore can strengthens anti-loosing effect further; And on the outer circumferential face of described nut body, offer the anti-skidding lines groove be inclined to set, then can effectively avoid people to occur skidding by during the tool into rotation nut bodies such as spanner.
It is radial through on the outer peripheral surface of connecting sleeve that the utility model can be set to described draw-in groove further.Such setting, not only can make to be formed between barb and draw-in groove block more solid and reliablely join fixing, and the assembly connection be conducive between barb and draw-in groove or fractionation.
The utility model also can be set to described contiguous block further and be preferably two pieces, and is pressed with Compress Spring between barb on two contiguous blocks.Such setting, under the effect of Compress Spring, can effectively prevent barb from skidding off in draw-in groove.
