Abstract
The utility model discloses a dodecagonal locking nut provided with an internal-tooth washer. The dodecagonal locking nut provided with the internal-tooth washer comprises a dodecagonal locking nut body, wherein a threaded hole is formed inside the dodecagonal locking nut body, an annular groove is arranged in the inner wall at one end of the threaded hole, the internal-tooth washer is embedded in the annular groove, a plurality of inner bulged teeth are evenly distributed on the inner wall of the internal-tooth washer in the circumferential direction, and the diameter of the inscribed circle of the internal-tooth washer and the threaded hole are provided with the same inner diameter and the same axis. The dodecagonal locking nut provided with the internal-tooth washer has the advantages of being stable and reliable in connection, and good in anti-loose effect.
Description
Technical field
The utility model relates to a kind of automobile-used fastening piece, specifically refers to a kind of 12 jiaos of locking nuts with the internal tooth packing ring.
Background technique
Nut is a kind of conventional fasteners, and it has internal thread and is used with bolt, the every field such as extensive use machinery, automobile making, pipe fitting connection.In the installation of existing wheel tyre, all be to be fixed on the bolt of wheel hub by locking nut.Yet the greatest problem that existing locking nut exists is: along with the long-time use of vehicle, becoming flexible can appear in locking nut, causes vehicle trouble.
Summary of the invention
The purpose of this utility model is the shortcoming and defect that exists in order to overcome prior art, can effectively prevent from becoming flexible and provide a kind of, improves the 12 jiaos of locking nuts with the internal tooth packing ring that connect stability.
For achieving the above object, the technical solution of the utility model is to include 12 jiaos of nut bodies, be provided with tapped hole in 12 jiaos of nut bodies, one end inwall of described tapped hole is provided with circular groove, the embedded installing of this circular groove is equipped with the internal tooth packing ring, making progress in the week of the inwall of this internal tooth packing ring uniformly is provided with a plurality of interior double wedges, and the inscribe diameter of a circle of described interior double wedge and tapped hole uniform internal diameter and etc. the coaxial inner conductor setting.
By this setting, utilize the internal tooth packing ring, when the utility model is screwed into bolt, the outside thread of the bolt interior double wedge of this internal tooth packing ring is rotated cutting, cuts out corresponding thread groove, thereby causes the internal tooth gasket deforms, be stuck on the bolt tightly, thereby realize anti-loosing effect.And by this settings, owing to the outside thread of bolt is that internal double wedge cuts, therefore, can adopt some softer metals to make by this internal tooth packing ring, such as copper aluminium etc.
The end that further setting is described hexagon nut body is provided with circumferential bulge loop, and the periphery of relative tapped hole is provided with annular groove, the coaxial inner conductor settings such as this annular groove and tapped hole on the exterior edge face of this circumferential bulge loop.By this setting, can allow the utility model be screwed to better the position.
In sum, it is reliable to the utlity model has stable connection, the advantage that anti-loosing effect is good.
Below in conjunction with specification drawings and specific embodiments the utility model is done further introduction.
