Abstract
The utility model relates to the technical field of fasteners, in particular to an anti-loosening nut. The anti-loosening nut is characterized by comprising a nut body and screws, wherein the middle part of the nut body is provided with an axial threaded hole; the side wall of the nut main body is provided with at least two grooves; the grooves are formed on the nut body at equal angles; radial threaded holes which are communicated with the axial threaded hole are formed in the grooves; and the screws are connected with the nut body through the radial threaded holes. According to the anti-loosening nut provided by the utility model, the side wall of the nut main body is provided with grooves capable of accommodating the screws, a bolt or a screw rod passes through the axial threaded hole in the nub body during use, and the screws are fastened when the nut body is rotated to a preset position till the screws are completely screwed into the grooves and are compressed together with the screw thread of the bolt or the screw rod, so that the nut can be effectively prevented from loosening; and moreover, the nut is compact in overall structure, and is attractive.
Description
Technical field
The utility model relates to technical field of fastening, is specifically related to a kind of lock nut.
Background technique
Nut is one of fastening piece commonly used in the mechanical field, and in use the phenomenon that gets loose of nut ubiquity needs running check, maintenance.In order to prevent that nut from getting loose, technological means commonly used is behind the cover upper gasket nut to be tightened on the bolt earlier on the bolt, rely on the frictional force between packing ring and nut to prevent nut loosening, but the anti-loosing effect that this kind means effect plays is limited, for addressing the above problem notice of authorization number be: the disclosed lock nut of CN202732619U, comprise nut body, have the axial screw thread through hole on the described nut body, it is characterized in that: have the radially tapped through hole that two tight screws of voltage supply are screwed on the sidewall of described nut body, two symmetrical and coaxial lines of described radially tapped through hole.This kind lock nut can prevent effectively that nut from getting loose, but screw radially is exposed at outside the nut influence operation easily after installing.
The model utility content
For addressing the above problem, the utility model provides a kind of lock nut, it is characterized in that: comprise nut body and screw, described nut body middle part has the axial screw thread hole, the sidewall of nut main body has at least two grooves, the groove equal angles is arranged on the nut body and is provided with the radial screw bore that is communicated with the axial screw thread hole in the groove, and described screw is connected with nut body by radial screw bore.
Further, nut body is cirque structure.
Further, groove is provided with four, and is evenly distributed along nut body excircle direction.
Further, the screw end that is screwed into the axial screw thread hole is provided with compact heap.
By above-mentioned to description of the present utility model as can be known,
The lock nut that the utility model provides uses, offered the groove that can hold screw at the sidewall of nut main body, bolt or screw rod pass in the axial screw thread hole of nut body in elder generation during use, after rotating to the precalculated position, nut body screws screw, after screw is screwed in the groove fully and compresses with bolt or screw flight, get final product, tighten and effectively to prevent nut loosening and nut compact overall structure, beautiful shape after making a decision.
Description of drawings
Fig. 1 is the plan view of the utility model specific embodiment lock nut.
Fig. 2 is the side view of the utility model specific embodiment lock nut.
Embodiment
Below the utility model will be further described by embodiment.
With reference to Fig. 1, shown in Figure 2, a kind of lock nut comprises nut body 1 and screw 2.Nut body 1 is cirque structure, and its middle part has axial screw thread hole 11, evenly is provided with four grooves 12 along nut body 1 excircle direction, is provided with the radial screw bore 13 that is communicated with axial screw thread hole 11 in the groove 12.Correspondences are provided with a screw 2 in each groove 12, and screw 2 one ends are connected with nut body 1 by radial screw bore 13, and the end that screw 2 is screwed into axial screw thread hole 11 is provided with compact heap 21.
With reference to Fig. 1, shown in Figure 2, when the utility model uses, bolt or screw rod pass in the axial screw thread hole 11 of nut body 1 in elder generation, after rotating to the precalculated position, nut body 1 screws screw 2, in screw 2 is screwed into groove 12 fully and compact heap 21 get final product after compressing with bolt or screw flight, can effectively prevent nut loosening and compact structure, beautiful shape.
Above-mentioned only is an embodiment of the present utility model, but design concept of the present utility model is not limited thereto, and allly utilizes this design that the utility model is carried out the change of unsubstantiality, all should belong to the behavior of invading the utility model protection domain.
