Abstract
The utility model relates to an anti-loosing screw thread coupling fastener, which is characterized in that a nut, a spring washer and the local shape of a flat washer are changed on the basis of the existing screw thread coupling fastener; the upper surface and the lower surface of the spring washer [4] are respectively provided with a plurality of convex teeth [5] on the upper surface of the spring washer and the convex teeth [6] of the lower surface of the spring washer, wherein the convex teeth [5] and [6] have the same quantity. The nut [2] is provided with a groove [3] on the peripheral surface of the lower part of the nut corresponding to the convex teeth [5] of the upper surface of the spring washer. The flat washer [7] is provided with a groove [8] on the peripheral surface of the upper part of the flat washer corresponding to the convex teeth [6] of the lower surface of the spring washer. When the spring washer [4] is screwed and flattened by the nut [2], the nut [2], the spring washer [4] and flat washer [7] are tightly engaged into a whole. Friction force between screw thread pairs of the fastener is enlarged as so to realize the effect of anti-loosing for the fastener.
Description
Technical field
The utility model relates to the scyewed joint fastening piece, is specially adapted to fastening piece is had the device of general anti-loosening requirement.
Background technique
Present widely used scyewed joint fastening piece, because under effects such as vibration and varying load, easily cause the fastening piece phenomenon that gets loose, it is more to solve at present the fastening piece technological means that gets loose, but the part loosing Prevention Technology remains in some defectives, not being the art designs complexity, lacking the actual meaning of using, is exactly problems such as anti-loosening effect is undesirable.
Summary of the invention
The purpose of this utility model is to take all factors into consideration some characteristics of existing anti-loosening scyewed joint fastening piece, provides a kind of behind nut screwing clamping, is difficult for loosening scyewed joint fastening piece for convenience detach again.
The purpose of this utility model is achieved in that anti-loosening scyewed joint fastening piece is by bolt, nut, spring washer and plain washer constitute, its specialization is, except that bolt, to nut, spring washer and plain washer local shape change, concrete condition is to have some grooves on nut lower circumference surface, on spring washer, lower surface has some and the corresponding double wedge of nut groove peace gasket recess, on the circumferential surface of plain washer top, have some and the corresponding groove of spring washer lower surface double wedge, when nut screwing clamping flattens spring washer, this moment nut lower circumference surface upper groove and tight interlock of spring washer upper surface double wedge, spring washer lower surface double wedge and the tight interlock of plain washer top circumferential surface upper groove simultaneously, nut like this, spring washer meshes whole with the plain washer three, increased frictional force between the fastener threads pair, make nut be difficult for counter-rotation, realized that fastener locking moves effect.
The utility model is compared with existing fastener locking braking technique has following advantage:
1, the utility model not only has anti-loosening effect, and dismounting only needs to strengthen strength pine withdrawing nut and get final product during fastening piece, so anti-loosening scyewed joint fastening piece can use repeatedly, anti-loosening and quick detachable can both the realization has more actual use meaning.
2, the utility model is simple in structure, and nut, bolt, spring washer and plain washer only change wherein nut, spring washer and plain washer local shape on existing standard spare basis, makes things convenient for enterprise to the transformation of product with adapt to user's use habit.
