Description
[technical field]
The utility model relates to the technical field of the technical field of fastening piece, particularly nut.
[background technique]
Be absolutely necessary at present production nut and be fastenedly connected instrument, but, use in some special occasions in the process of assembling, often there will be the problem that nut drops, so self-locking nut is a strength member that must not lack.And on some important vitals needing dismounting, self-locking nut such as often to get rusty at some reasons and not easily removing, this is not easy to fitting operation, causes manpower, the waste of material resources, and can damage parts to a certain extent.
[model utility content]
The purpose of this utility model solves the problems of the prior art exactly, proposes a kind of self locking type nut, nut can be made not easily to drop and convenient lubrication.
For achieving the above object, the utility model proposes a kind of self locking type nut, comprise the upper cap nut of hexangle type and the lower nut of hexangle type, nut is combined by upper cap nut and lower nut, upper cap nut and lower nut center line are at same axis, described upper cap nut and lower nut center are the tapped hole that model is identical, and the thread angle of the internal thread of tapped hole is 15 degree, and tapped hole is formed by connecting by upper screwed hole and lower tapped hole.
As preferably, the center of described upper cap nut has upper screwed hole and groove to be formed by connecting, and the axis of upper screwed hole and groove is all the center line of upper screwed hole, is provided with screw thread in groove.
As preferably, described lower nut is terraced axle, and lower nut is formed by connecting by tongue and macro-axis, and the side that the length of tongue is greater than the length tongue of groove is provided with outside thread, and the center of lower nut is lower tapped hole, and the side of tongue is provided with a through hole.
As preferably, described groove matches with outside thread.
The beneficial effects of the utility model: the utility model is by agreeing with the groove of upper cap nut and the tongue of lower nut, self-locking nut is served to the effect of support, anti-rotation, add the angle limits to helix angle, effectively can play the fixing of nut, thus reach the effect of Drop-proof; Be provided with a through hole convenience in the side of tongue and add Lubricants.
Feature of the present utility model and advantage will be described in detail by reference to the accompanying drawings by embodiment.
