The utility model is characterized in that at least one groove (2) is arranged on the inner wall of the nut (1), the cross section of the groove (2) is a semicircle; the angle between a transverse side (6) on the groove (2) and opposite to a plug sleeve (4) and the horizontal direction is not less than 90 degrees; a steel ball (3) is arranged in the groove (4), the outer surface of the steel ball (3) is knurled; at least one pair of plug sleeve grooves (5) is arranged on the outer side of the plug sleeve (4) in the axial direction, the height difference between the plug sleeve groove (5) and the plug sleeve (4) is a negative and the difference between the width of the plug sleeve groove (5) and the diameter of the steel ball (3) is a positive. The nut of the utility model is characterized that the steel ball is prevented from not sliding in the nut and the defensive antitheft function of the nut is improved greatly.
Description
Technical field:
The utility model relates to a kind of axial lock compact form fastening piece, is the anti-anti-theft nut that unloads of a kind of annular knurl stainless shot combined type specifically.
Background technique:
Anti-general smooth steel ball and the smooth pin contacts of adopting of anti-theft fastening piece of unloading of horizontal locking commonly used more, because its frictional force is less than normal, cause anti-theft fastening piece playing anti-unloading the antitheft time spent of doing, owing to occurring skidding between smooth steel ball and smooth pin and nut or laterally moving, make anti-reliability of unloading anti-theft feature reduce greatly.In addition, the present anti-anti-theft nut that unloads is installed the groove of ball or roller and is generally groove, and ball or roller easily come off when mounted, makes the poor reliability of nut.
The model utility content:
In order to overcome existing anti-problem of unloading the poor reliability of anti-theft nut, the utility model provides a kind of annular knurl stainless shot combined type the anti-anti-theft nut that unloads, this nut has the characteristics non-slip between ball and the nut that prevent, has improved the anti-anti-theft feature that unloads of nut greatly.
The technical solution of the utility model is: the anti-anti-theft nut that unloads of a kind of annular knurl stainless shot combined type, comprise nut, plug sleeve, has a groove on the inner hole wall of described nut at least, the cross section of described groove be shaped as semi-circle, the angle of the horizontal edge of a relative side with plug sleeve and substantially horizontal is not less than 90 ° on the groove, and groove is built-in with steel ball, described steel ball outer surface annular knurl, described plug sleeve outboard shafts is to having a pair of plug sleeve groove at least, the difference of the length of described plug sleeve groove and the length of plug sleeve is a negative, and the difference of the diameter of width and steel ball is a positive number.
Described nut is a hexagon nut, and the hardness of described steel ball is HRC35-60, and its diameter is at least 1.20mm, and the material of described plug sleeve is nonmetal plastic material, and the degree of depth of described groove and the difference of diameter of the steel ball are negative.
Advantage of the present utility model: owing to take such scheme, the external form of nut is identical with common hexagon nut, thereby very easy to use; Fluted on the inner hole wall of nut, in nut bore, be provided with plug sleeve again, the external diameter of plug sleeve is bigger slightly than nut inner hole diameter, thus plug sleeve difficult drop-off when having guaranteed that nut end is used; Steel ball surface knurling in the groove makes the frictional force of this assembled nut increase greatly, thereby has overcome the skidding when nut is fastening, has realized the anti-reliably anti-theft feature that unloads.

Embodiment:
The utility model is described in further detail below in conjunction with accompanying drawing:
By accompanying drawing 1 to shown in the accompanying drawing 5, the anti-anti-theft nut that unloads of a kind of annular knurl stainless shot combined type, comprise nut 1, plug sleeve 4, described nut 1 can be a hexagon nut, easy to use like this, has a groove 2 on the inner hole wall of nut 1 at least, the quantity of groove 2 also can have 2 or 3, the cross section of described groove 2 be shaped as the quadrant arc, be not less than 90 ° with the horizontal edge 6 of plug sleeve 4 relative sides and the angle of substantially horizontal on the groove 2, promptly horizontal edge 6 is a level or downward-sloping, and groove 2 is built-in with steel ball 3, the difference of the diameter of the degree of depth of groove 2 and steel ball 3 is a negative, and some can expose nut 1 interior threaded surface afterwards to make steel ball be lowered to groove 2.Described steel ball 3 outer surface annular knurls, can increase frictional force, thereby improve the anti-anti-theft feature that unloads of nut greatly, the material of steel ball 3 is a stainless steel, and hardness is HRC35-60, and diameter is decided according to the size of nut 1, nut 1 is big more, steel ball 3 is big more, but steel ball is at least 1.20mm, generally is no more than 4mm.There is a boss described plug sleeve 4 upper ends, can be stuck in nut 1 top, and are easy for installation in order to guarantee, the boss bottom can be a cone, and plug sleeve 4 is made by nonmetallic material, and certain elasticity is arranged, the external diameter of cone is slightly larger than nut 1 endoporus, in case detent plug cover 4 comes off.The outboard shafts of described plug sleeve 4 is to having a pair of plug sleeve groove 5 at least, the difference of the length of the length of described plug sleeve groove 5 and plug sleeve 4 is a negative, the bottom that is plug sleeve groove 5 is not a groove, the difference of the diameter of its width and steel ball 3 is a positive number, be the diameter of the width of plug sleeve groove 5 greater than steel ball 3, assurance steel ball 3 can be put into groove 2 by plug sleeve groove 5.
During this nut combinations, at first plug sleeve 4 is placed nut 1 endoporus, plug sleeve groove 5 aligns with nut groove 2, then steel ball 3 is placed in the plug sleeve groove 5, steel ball 3 slides onto in the groove 2 automatically, with 45 °-90 ° of plug sleeve 4 rotations, its plug sleeve groove 5 and recessed 2 dislocation, steel ball 3 promptly is enclosed in the groove 2, because the cone of plug sleeve 4 part is more bigger than nut 1 endoporus, add to nonmetallic material and make to have certain elasticity, this just makes plug sleeve 4 be difficult for coming off from nut 1 endoporus, so steel ball 3 can be enclosed in the groove 2.
Use when this annular knurl stainless shot combined type is anti-to unload anti-theft nut, the end that plug sleeve 4 on the nut 1 is had a boss outwardly, forward is screwed into, and plug sleeve 4 can be ejected by nut 1 endoporus automatically, form half arc wedge groove between the bolt outside thread of groove 2 and screw-in, after nut 1 locking, steel ball 3 is enclosed in the groove 2, when unscrewing when unloading nut 1 is counter, steel ball 3 can be subjected to the friction and the extruding of bolt and groove 2 immediately, thereby the direction that the wedge groove angle that forms to groove 2 and bolt is little moves, and then the bigger coupling mechanism force of formation, owing to annular knurl stainless shot 3 rough surface, guaranteed that it can not occur skidding and slippage when being rubbed and push, thereby reached the good anti-anti-theft feature that unloads simultaneously.
