Abstract
A kind of locking oblique groove metal insert nut, comprise nut body and internal thread metal insert, nut body bottom is tubular fluting body, and tubular external circumference symmetrical position of slotting has 3 rhombus skewed slots, metal insert stretches out body with 3 rhombuses, can the rhombus skewed slot of insert nut.Rhombus skewed slot axial depth equals inserts thickness, and metal insert is identical with the tubular fluting body degree of depth, can effectively stop inserts to move along screw rod direction inside nut.Rhombus sharp angle α is greater than nut inner thread lead angle β.Due to the difference of angle, rhombus acute angle is greater than nut inner thread lead angle, so nut and inserts changing of the relative positions lifting distance are greater than screw thread lifting distance, thus can effectively lock the fastening piece be in high vibration or dynamic load.Conbined usage metal insert of the present invention and slotted nut, what effectively prevent from causing due to vibration and dynamic load loosens, and compared with the existing technology, installing/dismounting is easy, without the need to punching on screw rod, improve the Safety performance of screw rod, and can repeatedly use.
Description
Technical field
The present invention relates to a kind of locking oblique groove metal insert nut.
Background technique
Regular screw threads fastening piece loosens to prevent tightening back nut, and the main method adopted has double nut to tighten, adds elastic washer, adds cotter pin, locked spacer, series connection steel wire, nylon inserts, nut fluting etc.The method that double nut is tightened still can loosen in the strong occasion of vibrations, frees nut and come off time serious, and owing to adding a nut, waste material, needs the length increasing bolt simultaneously.The relaxation effect adding elastic washer is not good, and adds cotter pin, locked spacer and series connection steel wire needs on screw rod or nut, carry out turnery processing, and technique is loaded down with trivial details.Nylon inserts anti-loose method repeated disassembled and assembled occasion is easy to damage, and some producer adopts metal insert to carry out locking, but due to problems such as structural designs, poor effect.Slotted nut refers to and process groove above hexagon nut, cotter pin is inserted in the hole of screw rod from the groove of nut, prevent the automatic Hui Song of nut, be mainly used in the occasion with oscillating load or alternate load, process on screw rod due to needs and portal, complex process, and reduce screw strength.
Publication number is the slotted nut that patent discloses a kind of rotatable adjustment included angle of CN 201016354Y, be made up of parts such as nut, tubular fluting body, straight pin, springs, in using process, the taper end that straight pin is given prominence to is inserted in the circular hole of spring, spring, straight pin are respectively charged in the circular hole in nut inner circle shrinkage pool plane, the groove of this slotted nut rotatably adjusts angle, during use, be arranged on and be equipped with on the screw rod of pin-and-hole, by rotating backward the angle of adjustment fluting body, can conveniently slot and the cooperation of screw rod pin-and-hole.Still there is the problems such as screw rod punching in this structure, technique is loaded down with trivial details, and under high load vibration environment pin-and-hole place easily produce stress concentrate, cause screw rod to rupture.
Summary of the invention
The present invention is directed to above-mentioned situation, provide a kind of structure simple, reasonable in design, anti-loosing effect is good, can repeatedly dismantle, long service life, reliable and stable locking skewed slot insert nut.
It is this kind of locking oblique groove metal insert nut that the present invention solves the problems of the technologies described above adopted technological scheme, comprise nut body and internal thread metal insert, nut body bottom is tubular fluting body, tubular external circumference symmetrical position of slotting has 3 rhombus skewed slots, metal insert stretches out body with 3 rhombuses, can the rhombus skewed slot of insert nut.
As preferably, rhombus skewed slot axial depth of the present invention equals inserts thickness, and metal insert is identical with the tubular fluting body degree of depth, can effectively stop inserts to move along screw rod direction inside nut.
As preferably, rhombus sharp angle α of the present invention is greater than nut inner thread lead angle β.Due to the difference of angle, rhombus acute angle is greater than nut inner thread lead angle, so nut and inserts changing of the relative positions lifting distance are greater than screw thread lifting distance, thus can effectively lock the fastening piece be in high vibration or dynamic load.
The present invention compared with the existing technology has the following advantages, and the rhombus skewed slot axial depth on nut equals inserts thickness, can effectively stop inserts to move along screw rod direction inside nut.Rhombus acute angle on nut is greater than nut inner thread lead angle, thus can effectively lock the fastening piece be in high vibration or dynamic load, improve the anti-loosening property of fastening piece.Meanwhile, without the need to punching on screw rod, improve the Safety performance of screw rod; Metal insert and slotted nut conbined usage, more effectively prevent due to vibration and dynamic load cause loosening; The present invention is without the need to parts such as straight pins, and installing/dismounting is easy, and can repeatedly use.

Label declaration: skewed slot nut 1, metal insert 2, nut body 3, rhombus skewed slot 4, tubular fluting body 5, nut inner thread 6, inserts body 7, rhombus stretch out body 8 and inserts internal thread 9.
Embodiment
Below in conjunction with embodiment, the present invention is described in further detail.
As shown in Figures 1 to 4, the present embodiment is made up of skewed slot nut 1, metal insert 2.Wherein skewed slot nut 1 comprises nut body 3, rhombus skewed slot 4, tubular fluting body 5 and nut inner thread 6.Metal insert 2 comprises inserts body 7, rhombus stretches out body 8 and inserts internal thread 9.
During assembling, first metal insert 2 is embedded the tubular fluting body 5 of skewed slot nut 1, and rhombus is stretched out body 8 and buckle in rhombus skewed slot 4, the insert nut after combination is screwed on screw rod.When tightening, skewed slot nut 2 promotes nut and inserts is tightened simultaneously, and because rhombus skewed slot 4 axial depth equals the thickness of metal insert 2, and metal insert 2 is identical with tubular fluting body 5 degree of depth, can effectively stop inserts to move along screw rod direction inside nut.When there are vibrations in the mechanism after tightening, rhombus acute angle due to the rhombus skewed slot 4 on skewed slot nut 1 is greater than nut inner thread 6 and inserts internal thread 9 lead angle, nut and inserts changing of the relative positions lifting distance are greater than screw thread lifting distance, under high vibration or dynamic load condition, effective locking of skewed slot nut can be realized.When the present invention assembles, without the need to punching on screw rod, improve the Safety performance of screw rod; Metal insert and slotted nut conbined usage, more effectively prevent due to vibration and dynamic load cause loosening; The present invention is without the need to parts such as straight pins, and installing/dismounting is easy, and can repeatedly use.
In addition, it should be noted that, the specific embodiment described in this specification, the shape, institute's title of being named etc. of its parts and components can be different.Allly conceive according to the present invention the equivalence or simple change that described structure, feature and principle do, be included in the protection domain of this patent.Those skilled in the art can make various amendment or supplement or adopt similar mode to substitute to described specific embodiment; only otherwise depart from structure of the present invention or surmount this scope as defined in the claims, protection scope of the present invention all should be belonged to.
