Abstract

The utility model discloses a locking bolt-nut component comprising a bolt and a nut fitting each other. A shank of the bolt is axially provided with a groove. The nut is polygonal. The locking bolt-nut component further comprises a washer. The washer comprises a washer body equal to the nut in diameter. The inner side of the washer body is provided with a projection clamped in the groove. The outer side of the washer body is radially provided with a pressure block. The locking bolt-nut component is simple in structure; on the basis of existing common bolt-nut, modification amount is low and cost is low; the locking bolt-nut component is large in fastening force and safe and reliable and is widely applicable to the field of bolt fastening.

Description

A kind of anticreep bolt nut assembly
Technical field
The utility model relates to bolton field, especially relates to a kind of anticreep bolt nut assembly.
Background technique
Bolt and nut is the fixing conventional link of mechanical connection, because existing bolt and nut is locked near screw thread, in there is vibrations or the long-term process of using, may cause thread looseness, the problem that nut gets loose.For the high parts of some precision requirement, getting loose of possible nut is fatal.Therefore need on the basis of original bolt and nut, transform, prevent that it from getting loose.
As Chinese Patent Application No. 200820009512.4 discloses a kind of Anti-releasing nut, be a polygonal block, its central authorities run through and are provided with an interior threaded hole, it is characterized in that: outside this interior threaded hole, one extends axially an annular flange flange; Can bestow this annular flange flange by external force, and make its distortion, and then tighten the cutting face of bolt, nut cannot be rotated on bolt, to form both fixing.But this model utility is large to the change amount of existing bolt and nut, and cost is high.
Model utility content
The purpose of this utility model is to provide a kind of anticreep bolt nut assembly, solves the fixing easily loosening problem of existing nut.
The utility model solves the technological scheme that its technical problem adopts: a kind of anticreep bolt nut assembly, comprise suitable screw bolt and nut, and the screw part of described bolt has a groove vertically, and described nut is polygonal; Also be provided with pad, described pad comprises and the isodiametric packing ring of nut, and the inner side of packing ring is provided with the projection being stuck in groove, and the outside of packing ring has been disposed radially briquetting.
For guaranteeing that briquetting is pressed on one side of nut, described anticreep bolt nut assembly is also provided with elastic spring.
For improving fastening strength, described briquetting is at least provided with 1.
The beneficial effects of the utility model: the projection by pad is stuck in groove, meanwhile, briquetting is pressed on the outside of nut, and nut can not be rotated.Simple in structure, fastening force is strong, is not easy to damage.And change littlely, cost is low.Described elastic spring can be finely tuned nut location, and briquetting is pressed on one side of nut, guarantees constant intensity.
Below with reference to drawings and Examples, the utility model is described in detail.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model bolt.
Fig. 2 is the structural representation of the utility model pad.
Fig. 3 is assembly structure schematic diagram of the present utility model.
Embodiment
Embodiment, as shown in Figures 1 to 3, a kind of anticreep bolt nut assembly, comprises suitable bolt 1 and nut 2, and the screw part 3 of described bolt 1 has a groove 4 vertically, and described nut 2 is polygonal; Also be provided with pad 5, described pad 5 comprises and the isodiametric packing ring 6 of nut 2, and the inner side of packing ring 6 is provided with the projection 7 being stuck in groove 4, and the outside of packing ring 6 has been disposed radially briquetting 8.Described briquetting 8 arranges 1, also a plurality of briquettings 8 can be set simultaneously, and each briquetting 8 is all pressed on the corresponding limit of nut, improves fastening force.
For guaranteeing that briquetting is pressed on one side of nut, improve fastening force, described anticreep bolt nut assembly also comprises elastic spring 9.
During assembling, first fixed block 10 is inserted in bolt, is then inserted in successively elastic spring 9, pad 5, finally screw in nut 2, when nut 2, tighten while putting in place, by briquetting 8 bendings, briquetting 8 is pressed on one side of nut 2.If there is deviation briquetting position and nut position on one side, by elastic spring 9, finely tune.
