Abstract
The utility model relates to an antitheft nut is prevented unloading by hexagon combination formula annular knurl roller. Main the preventing of having now of solving unloads the antitheft nut steel ball or sells the problem that easily drops and make theftproof nature difference. Its characterized in that: the inner wall of nut (1) on open and have at least one recess (2), the cross section of recess (2) is half -circular arc, and recess (2) built -in flexible piece of outer deployment (5) that has annular knurl roller (4), annular knurl roller (4), nut (1) outer wall upper end is equipped with the boss, and the cover has the lantern ring (3) on the outer wall of boss lower part. This antitheft nut is prevented unloading by hexagon combination formula annular knurl roller's roller is difficult for droing, has the dual layer protection function, simple to operate, prevent unloading the theftproof effectual.
Description
Technical field
The utility model relates to a kind of axial lock compact form fastening piece, and a kind of hexagon combined type knurling roler is anti-specifically unloads anti-theft nut.
Background technique
Conventional locking prevents that unloading anti-theft fastening piece generally adopts smooth steel ball and smooth pin contacts, because its frictional force is less than normal, cause anti-theft fastening piece rise anti-unload antitheft time, due to pearl, occur between pin and nut skidding or slippage, the anti-theftproof performance that unloads is reduced, when mounted due to high-lift operation cause sometimes smooth pearl, pin come off, make the poor reliability of nut, do not have anti-theft function.
Summary of the invention
Existingly anti-anti-theft nut steel ball is unloaded or pin easily comes off and makes the deficiency of anti-theft difference in order to overcome; the utility model provides a kind of hexagon combined type knurling roler to prevent unloading anti-theft nut; this hexagon combined type knurling roler prevents the roller difficult drop-off unloading anti-theft nut; there is double shielding function, easy for installation, anti-ly unload good anti-theft effect.
The technical solution of the utility model is: a kind of hexagon combined type knurling roler is anti-unloads anti-theft nut, comprise nut, the inwall of described nut has at least one groove, the cross section of described groove is semicircular arc, and groove is built-in with knurling roler, the outside of knurling roler is equipped with elastomer block; Described nut outer wall upper end is provided with boss, and on the outer wall of boss bottom, cover has the collar.
It is Spielpassung between the described collar and nut.
Described knurling roler surface detail is the one in S shape, vertical bar shaped, rhombus.
The utility model has following beneficial effect: owing to taking such scheme, the inner hole wall of nut is provided with groove, knurling roler and elastomer block is provided with in groove, when carrying out dismounting, knurling roler is subject to the friction and Extrusion of nut elastomer block, the direction slippage little to the wedged gap of groove and bolt pattern and form larger coupling mechanism force, plays and anti-ly unloads anti-theft feature; Hold cylinder place to increase the collar under the nut, because being movable between the collar and nut, thus more playing and anti-ly unload antitheft effect.

Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail:
By shown in Fig. 1 to Fig. 4, a kind of hexagon combined type knurling roler is anti-unloads anti-theft nut, and comprise nut 1, described nut 1 outer surface is hexagon, adopts special spanner when tightening.The inwall of described nut 1 has at least one groove 2, the quantity of groove 2 can be 1-4, the cross section of described groove 2 is semicircular arc, and groove 2 is built-in with knurling roler 4, the outside of knurling roler 4 is equipped with elastomer block 5, the width of described groove 2 is greater than the diameter of knurling roler 4, and knurling roler 4 surface detail can be S shape, vertical bar shaped or rhombus and the diameter of knurling roler 4 is not less than 1mm.Described nut 1 outer wall upper end is provided with boss, and on the outer wall of boss bottom, cover has the collar 3, and be Spielpassung between the described collar 3 and nut 1, make can mutually rotate therebetween, gap is 0.1-1.0mm.Screw thread 1 and the collar 3 bottom surface are pasted with adhesive sticker 6.
During this nut combinations: first squeeze into appropriate silicon sealant in groove 2, then successively knurling roler 4 and elastomer block 5 are pasted.When nut 1, knurling roler pin 4, elastomer block 5 assemble after, the collar 3 is inserted in outside the cylindrical body of nut 1 lower end, then bottom surface paste on adhesive sticker 6.
When using this hexagon combined type knurling roler to prevent unloading anti-theft nut, be selected to this product of bolt same size, nut 1 upper groove 2 opening is screwed into inwardly; Form half arc wedge groove between the bolt outside thread of groove 2 and screw-in, after nut 1 is locked, knurling roler 4 is enclosed in groove 2.When by nut 1 unscrewed loose unloading, knurling roler 4 can be subject to the friction and Extrusion of bolt, groove 2 and elastomer block 5 immediately, thus form larger coupling mechanism force to the groove 2 direction slippage little with the wedged gap of bolt pattern, add that the collar 3 is movable, ensure that and artificially cannot to be screwed out when nut is not destroyed, play that good bilayer is anti-unloads anti-theft feature.
Claims (3)
1. a hexagon combined type knurling roler is prevented unloading anti-theft nut, comprise nut (1), be characterised in that: the inwall of described nut (1) has at least one groove (2), the cross section of described groove (2) is semicircular arc, and groove (2) is built-in with knurling roler (4), the outside of knurling roler (4) is equipped with elastomer block (5); Described nut (1) outer wall upper end is provided with boss, and on the outer wall of boss bottom, cover has the collar (3).
