Description
Technical field:
The utility model relates to a kind of nut, particularly a kind of seperated auto-lock lock nut.
Background technique:
The bolt assembly that the fastening piece of usual machinery scyewed joint is made up of bolt, nut, spring washer etc., bolt generally relies on nut self locking.Wherein lock nut mainly contains following several: namely built-in nylon anti-slow ring type lock nut, built-in anti-slow steel-sheet type lock nut, built-in anti-slow coil spring formula lock nut, built-in anti-slow pin (ball) formula lock nut, change thread profile angie type lock nut, open anti-slow slot type lock nut at sagittal plane, by screw thread punching distortion to increase nut and bolt friction torque formula lock nut etc.In addition, adopt the associating retention device formed from external action to realize having of nut anti-looseness: to add spring washer locking, add locked spacer locking, utilize tackiness agent locking, rush the forms such as deformation point is locking in bolt, nut joint.Above anti-loose method, cuts both ways, but under, the operating mode such as ocsillator strenght is large, the vibrational period is long high in vibration frequency, is difficult to meet locking requirement.And the nut used in the market pretightening force decline under vibration environment causes connecting and loosens, can not play and be fastenedly connected, especially easily initiating failure and accident.
Model utility content:
The purpose of this utility model is just to provide a kind of seperated auto-lock lock nut to solve the problem, and solves nut pretightening force decline under vibration environment and causes connection to loosen, can not play problems such as being fastenedly connected.
In order to solve the problem, the utility model provides a kind of technological scheme: a kind of seperated auto-lock lock nut, and its innovative point is: comprise recessed nut main body, recessed nut thread hole, recessed nut groove, knurled nut main body, knurled nut tapped hole and knurled nut boss; Described recessed nut main body middle position is provided with recessed nut thread hole; Described recessed nut groove is located at recessed nut main body lower center position; Described knurled nut main body middle position is provided with knurled nut tapped hole; Described knurled nut boss is located at knurled nut body top; Described recessed nut main body is positioned at the positive upside of knurled nut main body.
As preferably, described recessed nut groove side is provided with tapering.
As preferably, described knurled nut boss center line departs from knurled nut tapped hole center line.
As preferably, described knurled nut boss side surfaces is provided with tapering.
As preferably, described recessed nut groove is identical with described knurled nut boss side surfaces tapering.
As preferably, described recessed nut thread hole and knurled nut tapped hole are the tapped hole of same specification.
As preferably, maximum limit, described knurled nut boss top is less than maximum limit bottom recessed nut groove.
The beneficial effects of the utility model:
(1) the utility model have rational in infrastructure simple, cost of production is low, easy for installation, arranges self locking anti-loose nut, to ensure that under vibration environment pretightening force can not fail to cause connecting and loosen, thus decrease the generation of initiating failure and accident.
(2) the utility model arranges knurled nut boss center line and departs from knurled nut tapped hole center line, produces radial pressure, form radial locking friction torque during use to attachment bolt.
(3) to arrange recessed nut groove identical with described knurled nut boss side surfaces tapering for the utility model, cooperation when ensure that connection and stability.
