Abstract
The utility model relates to an anti-dropping locknut. According to the anti-dropping locknut, one end of the locknut is provided with a diamond spring; the diamond spring has self-alignment and floating functions, and is not assembled in a rigid mode; in order to enter ring slots of external threads conveniently, the position of the diamond spring can be adjusted automatically, so that the nut can be screwed into the external threads freely; after the nut reaches the set position, the diamond spring enters the preset ring slots in the external threads to fulfill the anti-dropping aim; and the other end of the anti-dropping locknut is provided with a locking mechanism, so that the effective moment locking of the connected external threads can be achieved. The anti-dropping locknut is suitable for the environment in which operating space is narrow and a connecting pair operates in the vibration state, and is easy to machine, deform and operate, reliable in connection and wide in application range.
Description
Technical field
The utility model belongs to mechanical manufacturing field, specifically, relates to a kind of Drop-proof locking nut, can be widely used in industries such as machinery, electronics.
Background technique
The normal locking nut that adopts in mechanical industrial structure connects.The common lock jack panel adopts the screw thread mode of texturing to produce coupling mechanism force.In many structures connections,, use the common lock jack panel can cause automatic obscission,, need the nut of a kind of ability auto lock and Drop-proof therefore in order to address this problem because its working environment is in the high vibration state.
The model utility content
The utility model technical problem to be solved is the deficiency to existing technology, and a kind of Drop-proof locking nut is provided, and this nut can be realized self-locking and Drop-proof, and easy to operate.
The technological scheme of the utility model is following:
A kind of Drop-proof locking nut; In Drop-proof locking nut one end rhombus spring is set; When nut body is connected with corresponding threaded male component, the rhombus spring feed to outside thread annular groove the time, can freely rotate and along with nut and zero relative rotation of outside thread move axially; The locking mechanism that is arranged on the Drop-proof locking nut the other end gets into working state, and the Drop-proof locking nut is rotated in the forward or during counterrotating, locking mechanism locking or unclamp.
End at nut body offers the groove that the rhombus spring is set, and the rhombus spring is placed in the groove, does not fix at the circumferencial direction of groove, and in the scope of axial groove width, realizes moving about.
The rhombus spring can in nut body, move about and the annular groove in outside thread in axially move, the axially movable scope of rhombus spring is less than or equal to externally threaded groove width, stops Drop-proof locking nut moving axially outside the restriction of setting, and realizes Drop-proof.
Locking position in the locking mechanism is a square, can realize that the deformation force when matching with circular threaded male component reaches locking effect.
The material of described Drop-proof locking nut can be selected a kind of in stainless steel, low-carbon alloy steel, titanium alloy, the Cuprum alloy for use.
There is lubricant coating on the surface of Drop-proof locking nut.
The beneficial effect of the utility model is: adopts the utility model and regular screw threads to screw, not only can realize linkage function, and can Drop-proof and locking.

Embodiment
In the utility model, the rhombus spring in the Drop-proof locking nut has motility, and its size matches with the screw thread that is connected, and can conveniently screw in and be fed to along thread groove the annular groove of setting.Enter into the annular groove of desired location when the rhombus spring after; The constraint release that it received in the spiral chute of screw thread originally; Automatically spring in the annular groove, the rhombus spring can freely rotate and move axially when nut continued rotation, but axially movable scope is limited to the groove width scope on the threaded male component; Thereby stop Drop-proof locking nut moving axially outside the restriction of setting, realize Drop-proof; What produce when rotating in the axial width scope of nut annular groove on threaded male component moves axially; The locking mechanism of Drop-proof locking nut along with nut with respect to the precession of threaded male component with screw out moving axially of producing; Progressive contacting and disengaging realized with circular threaded male component in its square position, thereby realization Drop-proof locking nut is locked and unclamped.
Claims (7)
