Abstract
An anti-loose anti-theft nut consists of a heptangular prism which is equipped with two semi-arc wedged grooves, balls bearing and a plug sleeve. A set of unilateral semi-arc wedged grooves is arranged at the axial setting position of the nut internal hole and the balls bearing are placed in the grooves. A matched bolt is screwed down in the process of installation and the plug sleeve is extruded from the nut and the balls bearing are sealed in the semi-arc grooves. In the process of applying loose force, great tangential resistance force is produced between the balls bearing and the bolt threads to lock the loose force in a plurality of positions; with the unique design of unequal shape and semi-arc wedged grooves in the internal hole, the reliable anti-loose anti-theft function can be realized.
Description
Technical field
The utility model is a kind of seven limit ball anti-loose anti-theft nuts.
Background technique
The utility model is in " annular knurl roller the anti-loose anti-theft nut " (patent No.: the further improvement of making on basis ZL2004201071896): (1) nut inner hole wedge slot end face sealing; (2) the nut profile adopts seven prisms.External and internal compositions is in conjunction with realizing anti-loose anti-theft function more reliably.
Summary of the invention:
The utility model is made up of endoporus half arc wedge groove seven limit nuts, ball and plug sleeve.
Endoporus half arc wedge groove seven limit nuts of the present utility model are at the nut inner hole desired location, process two and half curve baths vertically, and its curved line helps ball and unloads force direction along pine and roll along cambered surface, and the nut profile adopts equilateral Heptagon.
Plug sleeve of the present utility model is made by the soft nonmetallic material of rubber-like, and there is one group of vertical tri-prism boss the outer ring, and the boss race diameter is slightly larger than the nut path, and plug sleeve is not dropped.Plug sleeve cylindrical and nut path are slightly gapped, to guarantee that ball can rest in half curve bath.
When the utility model implement to be installed, plug sleeve can be ejected nut along with the screw-in of bolt, and ball is clipped between bolt thread and the nut half arc wedge cell wall in the mode of interference fit.When implementing pine when unloading, ball unloads under the power effect pine and rolls to the curve bath sharp corner, and it is opposite that the tangential resistance that produces along with the increase of magnitude of interference and pine are unloaded power, stoped the pine of nut to be unloaded, thereby realized reliable locking unloading functions.

Among the figure: (1) nut; (2) ball; (3) plug sleeve; (4) half curve baths
Embodiment:
The utility model package assembly has half curve bath nut (1), ball (2) and plug sleeve (3) to form as shown in Figure 1 and Figure 2, can select single nut or double nut form as required, and the outer nut in the double nut form plays locking functions.
Nut (1) structure of seven limit balls, half arc wedge groove of the present utility model as shown in Figure 3, Figure 4, at nut (1) endoporus desired location, axially process one group of wedge groove (4), wedge groove (4) cross section is unidirectional half arc, the sealing of wedge groove (4) both ends of the surface, the degree of depth of wedge groove and height are determined by ball (2) diameter.The profile of nut (1) is Heptagon, must use special spanner.
Ball of the present utility model (2) as shown in Figure 5, ball (2) diameter is decided according to different size screw-thread fit size.
The utility model plug sleeve (3) is made by flexible nonmetallic material, and periphery has several groups of uniform vertical beads, and the circumscribed circle diameter of bead is slightly larger than nut (1) path, does not come off from nut inner hole to support plug sleeve (3).The outside diameter of plug sleeve (3) is slightly smaller than nut (1) path, does not drop in transportation and installation process but must push up firm ball (2).
The utility model is stained with butter with ball (2) earlier when assembling, be placed in the two wedge slotted eyes (4), fills in plug sleeve (3) then.Ball (2) must be blocked in the position of plug sleeve (3), and two wedge grooves are all covered in, and does not drop before installing to guarantee ball (2) (4) in the wedge slot of nut (1).Stay the use convenient for assembly of 1-2 button screw thread at nut (1) supporting surface one end.
When implementing the utility model is installed, screw in supporting bolt at nut (1) supporting surface, plug sleeve (3) can be pushed out nut (1) endoporus, and ball (2) is sealed in the half arc wedge groove of staying nut (1) and bolt formation (4).When fastening nut (1), ball (2) promotes the lower edge curved line and is rolled to half arc wedge groove bosom tightening tangential force, does not produce resistance; When loose removing nut (1), ball (2) unloads tangential force pine and promotes the lower edge curved line and roll to half arc wedge groove (4) sharp corner, and along with the increase of magnitude of interference, the tangential resistance of generation is increasing, unloads tangential force greater than pine, thereby has stoped the pine of nut (1) to be unloaded.
Nut (1) profile adopts asymmetric equilateral simultaneously, and instrument commonly used can't clamp and loose removing nut (1), and the economic benefits and social benefits unification makes the utility model realize anti-loose anti-theft function more reliably.
Claims (3)
1. limit ball anti-loose anti-theft nut, the nut (1), ball (2) and the plug sleeve (3) that are had two and half arc wedge grooves by endoporus are formed.
2. seven limit ball anti-loose anti-theft nuts according to claim 1 is characterized in that: two unidirectional half arc wedge grooves (4) of the axial desired location processing of nut (1) endoporus, and wedge groove closed at both ends, nut (1) profile adopts asymmetric equilateral.
3. seven limit ball anti-loose anti-theft nuts according to claim 1 is characterized in that: plug sleeve (3) periphery has one group of vertical boss, and slightly larger in diameter is used for fixing interim plug sleeve in the nut path; Plug sleeve (3) external diameter is slightly less than nut (1) path, does not come off in installation and transportation process to guarantee ball (2).
