Abstract
Disclosed are a loose-proof flange nut and a matching washer. A flange part is arranged on the nut body of the flange nut, the end face of the flange part is provided with continuous anti-slip teeth to form a loose-proof anti-slip structure, and the upper end face of the washer body is also provided with continuous anti-slip teeth which are engaged with corresponding continuous anti-slip teeth arranged on the end face of the flange part. The continuous anti-slip teeth disposed on the flange part of the loose-proof flange nut can greatly increase loose-proof anti-slip friction force, engaging and corresponding anti-slip teeth are also disposed on the surface of the matching washer, the attachment strength is excellent after the anti-slip teeth are mutually contacted and matched, loosing due to relative rotation can not be caused even in severe vibration, and the loose-proof performance is very reliable.
Description
Technical field: the utility model relates to a kind of flange nut, and relates to a kind of packing ring.
Background technique: there have many equipment need use flange nut to carry out in industrial field to be fastening locking, but general flange nut and packing ring contact matching face all are the plane, when situation about being subjected to than high vibration, nut relatively rotates with packing ring possibly and gets loose, and fastening reliability is not high.In the strict equipment of some fastening anti-loosening properties, also may influence normal operation, produce safety problem.
Summary of the invention: at the deficiencies in the prior art, the utility model provides a kind of fastening performance reliable locking flange nut, and a kind of locking supporting packing ring of strengthening is provided simultaneously.
Flange nut of the present utility model is provided with flange part on nut body, the end face of flange part is provided with continuous slideproof tooth, constitutes locking Skidproof structure.
Packing ring of the present utility model also is provided with continuous slideproof tooth on the upper-end surface of circle body, and and corresponding flange part end face on slideproof tooth coincide mutually.
Nut flange part of the present utility model is provided with slideproof tooth, can increase the frictional force of locking on-slip greatly, and supporting washer face also has the corresponding slideproof tooth that coincide, tightness is very good after both contact matching, do not get loose even also can not relatively rotate when high vibration, anti-loosening property is very reliable.
Further specify the utility model below in conjunction with drawings and Examples.
Description of drawings: Fig. 1 is the stereogram of flange nut;
Fig. 2 is the front view of Fig. 1;
Fig. 3 is the stereogram of packing ring;
Fig. 4 is the front view of Fig. 3;
Fig. 5 is used in combination view.
Embodiment: as depicted in figs. 1 and 2, nut body 1 is provided with flange part 2, and the end face of flange part 2 is provided with continuous slideproof tooth 3, constitutes locking Skidproof structure.Slideproof tooth 3 can adopt unidirectional helical teeth, and performance is more reliable.Packing ring also is provided with continuous slideproof tooth 3 then as shown in Figure 3 and Figure 4 on the upper-end surface of circle body 4, and and corresponding flange part 2 end faces on slideproof tooth 3 coincide mutually.The slideproof tooth 3 of circle body 4 also can be unidirectional helical teeth.And, also can be provided with slideproof tooth 3 on the other end of circle body 4, the bottom surface of circle body 4 also contacts anti-skiddingly with other surface so in use, and the anti-loose performance during vibration is better.
During actual the use, as shown in Figure 5, flange part 2 end faces of nut body 1 and the upper-end surface contact matching of circle body 4, both slideproof tooth 3 coincide mutually, anti-loose more reliable performance after particularly adopting unidirectional helical teeth to coincide, 3 of slideproof tooth of circle body 4 bottom surfaces and surface, installation place are tightly touched anti-skidding.
