Ejection, and annular alice 62 is arranged in barrier structure 5；Finally, screw thread is opened up in the endoporus 2 of nut body 1, and in screw thread
Diameter is less than the overall diameter of annular alice 62, and annular alice 62 can be made to be present in 5 inner cavity of barrier structure.
In order to make this end nut be used in wider range, such as Fig. 5 further includes further inner cone 7, and described half
61 inner cavity of spherical cap, which is pasted, is fixed with inner cone 7, and 7 one end of inner cone is adapted with 61 inner cavity of hemispherical cap body, by viscous
Patch is fixed, and double of spherical cap 61 has supporting role, and frustum structure is then arranged in 7 the other end of inner cone, and can be used
Deformable plastics or rubber material, specifically, 7 lower end of the inner cone it is tapered and be screwed into the nut body 1
Threaded bolt contacts.Therefore, it is screwed into nut body 1 in bolt, with being constantly screwed into, it can be achieved that inner cone 7 for bolt
It squeezes, then outside double of spherical cap 61 is squeezed inner cone 7 so that annular alice 62 is contacted with barrier structure 5 and realized
Sealing effect.
In order to improve sealing effect, make to be in close contact between ring flange 4 and component to be fixed, such as Fig. 2 and 4, further,
Further include annular groove 8 and cushion rubber 9, annular groove 8, the annular groove 8 and the nut sheet are offered on 4 outer end face of the ring flange
1 endoporus 2 of body is concentric, is disposed around the setting of 1 endoporus of nut body, 2 outer ring, and specifically when installation, glue is pasted in the annular groove 8
Circle 9,9 outer end face of the cushion rubber is slightly above 4 end face of the ring flange.When specifically used, nut body 1 is twisted and is located on bolt,
4 lower end of ring flange is contacted with component to be fixed, and be arranged cushion rubber 9 can between ring flange 4 and component to be fixed shape
At buffering, and bolt is enclosed by cushion rubber 9 and is set, opposing seal can be formed between cushion rubber 9, ring flange 4 and component to be fixed
Space, can not only realize the sealing effect of water proof and dust proof, and air can be completely cut off, further increase the effect of anti-corrosion
Fruit.And the setting of cushion rubber 9 can play damping, buffering effect, reduce the frictionally damage of ring flange 4 and component to be fixed.
Using the technical solution of the utility model, in 1 process of nut body, tarpaulin 6 is mounted on and blocks knot
In structure 5, and when nut body 1 twists and is located at bolt end, bolt squeezes 6 inner end of tarpaulin, is 6 inner end of tarpaulin and screening
It keeps off structure 5 to be fitted close, has the effect of water proof and dust proof, and sealing effect is good；And cushion rubber 9 is provided on 4 end face of ring flange,
So as to make ring flange 4 and fixed part are in close contact, have the function of dust and water protection, and the setting energy of cushion rubber 9
Enough enclose bolt sets, and completely cuts off air, further improves anti-corrosion ability.The utility model is simple in sturcture, ingenious in design, installation
It is easy, water proof and dust proof anti-corrosion effect is good, and service life is long.
The above descriptions are merely preferred embodiments of the present invention, is not intended to limit the utility model, for this
For the technical staff in field, various modifications and changes may be made to the present invention.It is all in the spirit and principles of the utility model
Within, any modification, equivalent replacement, improvement and so on should be included within the scope of protection of this utility model.
