Description
Technical field
This utility model relates to machinery manufacturing technology field, more particularly, it relates to a kind of Self-lock nut.
Background technology
In mechanical manufacturing field, nut is the most frequently used part. Nut is generally from being a body, and outer surface is hexahedro column shape shape, in order to coordinate tightening tool to rotate nut. Nut center is tapped through hole, is generally dextrorotation male screw, and screw thread form has triangle, trapezoidal, rectangle etc.
Although nut is in daily use, but the locking of nut is always up a problem being less susceptible to solve. Common anti-loose method is also a lot, such as spring washer, double nut, metal lock washer, binding nut, slotted nut, Toothed Lock Washer, the locking of nylon inserts, split pin, stop washer, duplex stop washer, steel wire concatenate, stick up shape packing ring, concave cone face lock washer etc., too numerous to enumerate. But general analysis, the locking measure of packing ring class, depend on the elastic qualities of packing ring, and packing ring easily partially or completely follows the string when long-term pressurized, thus losing the effect of supplementary pretightning force. A class is had to belong to perforation more locking, for instance split pin, steel wire concatenation etc. This locking mode needs to destroy screw rod itself. The directional requirement of split pin, it is necessary to by nut alignment pin holes, pin just can penetrate. But the orientation of nut alignment pin holes is not necessarily nut and is just tightened to the position of tightening moment, and this is formed for contradiction. Steel wire concatenation does not have this directivity requirement, but is commonly used in screw head, and needs set screws are used. Double nut utilizes after nut screwing clamping, and top effect is locking, but from installation requirement it can be seen that secondary nut is installed to mother nut and by between tightening face, and secondary nut adopts slim, tightens inconvenience. Etc. the pros and cons having himself of locking measure, no longer exhaustive here.
Accordingly, because prior art exists above-mentioned technological deficiency, it is those skilled in that art's technical problems urgently to be resolved hurrily.
Utility model content
The purpose of this utility model is for providing a kind of Self-lock nut, it is intended to the nut solving to exist in prior art easily loosens, the problem of anti-loosing effect difference.
For achieving the above object, this utility model provides following technical scheme:
A kind of Self-lock nut, including nut body, main screw, secondary screw, perforation, locking device and holding screw, described nut body is provided with main screw, the described main screw sidepiece of described nut body one end is provided with time screw, described main screw is paralleled with described screw, it is provided with holding screw in described screw, described nut body sidewall offers perforation, the axis of the axis described nut body of traverse of described perforation, described perforation communicates with described main screw, described holding screw passes described perforation from described screw, it is provided with locking device in described perforation, described holding screw is located on described locking device.
Preferably, described locking device includes location bar, hole, location, elastic component, locating piece and self-locking tooth, location bar it is provided with in described perforation, described location bar is provided with hole, location, described location boom end connects elastic component, and described elastic component connects locating piece, and described locating piece top connects self-locking tooth, described self-locking tooth contacts fixing with the screw rod in described main screw, and described holding screw is located in hole, described location.
