Abstract
The utility model discloses a dodecagonal sealing and self-locking nut which comprises a self-locking nut and 12 apical teeth evenly arranged on an outer cylinder of the self-locking nut. The outer cylinder of the utility model is evenly provided with the 12 apical teeth, so that the wrenching angle in use is small, which is suitable for the users to operate in quite narrow areas; in addition, after the 12 apical teeth of the utility model reef and deform, the locking is firmer. Moreover, a sealing ring is inlaid at the bottom of the self-locking nut and the inlaid structure integrates the self-locking nut with the sealing ring during assembly, so that the sealing performance of the dodecagonal sealing and self-locking nut is more reliable and the service life is longer.
Description
Technical field
The utility model relates to a kind of fastening piece, particularly a kind of 12 jiaos of sealing self-locking nuts.
Background technique
Self-locking nut be because himself structural feature can be finished the connection and the locking of nut simultaneously, and can be high temperature resistant, and is widely used in Aeronautics and Astronautics aircraft and the engine device thereof, and the vibration that produces when preventing aircraft and engine operation comes off it.Adopt self-locking nut that many structures of motor and aircraft are thoroughly simplified, reduce the weight of aircraft and motor greatly, improve functional reliability, significant to improving aeroplane performance.But the outer rim of present self-locking nut mostly is pentagon, Hexagon, and this makes it need bigger twisting angle in use, and particularly when narrow region was worked, the user was difficult to it is tightened, and this has just limited the Applicable scope of self-locking nut.In addition, existing self-locking nut sealing in use is relatively poor, makes that its working life is shorter.
Summary of the invention
Problem to be solved in the utility model is: provide a kind of twisting angle little, sealability is reliable, 12 jiaos of sealing self-locking nuts that working life is long.
The utility model is to constitute like this: it comprises self-locking nut body 1, evenly is provided with 12 angle teeth 3 on the outer cylinder of self-locking nut body 1.
In 12 jiaos of above-mentioned sealing self-locking nuts, be embedded with seal ring 2 in the described self-locking nut body 1 bottom interior threaded hole.
Owing to adopt technique scheme, compared with prior art, evenly be provided with 12 angle teeth on the outer cylinder of the present utility model, in use the twisting angle is little to make it, is suitable for the user and is operating than narrow region; And 12 jiaos of teeth of the present utility model are locked more firm after closing up and being out of shape.In addition, be inlaid with seal ring in self-locking nut body bottom, and embedded structure when making assembling self-locking nut body and seal ring become one, make that sealability of the present utility model is more reliable, working life is also longer.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the figure that partly cuts open of the present utility model;
Reference character:
1-self-locking nut body, 2-seal ring, 3-angle tooth.
Embodiment
Embodiment of the present utility model: structure of the present utility model as depicted in figs. 1 and 2, it comprises existing commercially available self-locking nut body 1, self-locking nut body 1 can adopt various metallic material to make, be preferably and adopt refractory alloy GH2132 to make, during making, on the outer cylinder of self-locking nut body 1, evenly make 12 angle teeth 3; In order to strengthen sealability of the present utility model, can in self-locking nut body 1 bottom interior threaded hole, inlay seal ring 2, seal ring 2 can adopt teflon to make.
The utility model in use, pretightening force of its locking back self-locking nut body 1 makes that the mosaic structure of seal ring 2 is more stable
