Description
Technical field
The utility model relates to a kind of compound seal antivibration anti-rotation sheet, and being mainly used in rail traffic vehicles has seal request and adjacent hexagon head bolt number is not less than the position of two.
Background technique
The roof location of rail traffic vehicles is provided with some functor and installs, infiltrate in car for preventing rain and cause the damages such as electrical system, with elastomers such as rubber as Sealing, but the elastomer such as rubber can be extruded even damaged after pretension bolt, also there will be the accelerated ageing phenomenons such as creep because the amount of deformation too large time one is long and cause seal failure.For this reason, alleviate above-mentioned situation with reduction tools for bolts ' pretension moment of torsion, but rail traffic vehicles vibration level is comparatively large, prefastening torque does not reach specified value bolt and very easily gets loose, can only shortening proof cycle, repeatedly beat locking mark and solve, maintenance maintenance man-hour and risk factor are increased.
Therefore seeking one, that tools for bolts ' pretension moment of torsion can be made to reach requirement is non-maintaining, and the compound seal antivibration anti-rotation sheet that Long-Time Service can not produce seal failure is particularly important.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency, provides a kind of.
The purpose of this utility model is achieved in that
A kind of compound seal antivibration anti-rotation sheet, it comprises anti-rotation sheet from top to bottom successively, reinforced sheet and elastic ring, described anti-rotation sheet comprises the anti-rotation sheet body at middle part, described anti-rotation sheet body is provided with at least two anti-rotation spacing holes, anti-rotation spacing hole is outside equipped with three groups of plectrums, described reinforced sheet comprises the reinforced sheet body at middle part, described reinforced sheet body is provided with at least two and strengthens spacing hole, reinforced sheet body and the reinforcement position of spacing hole of described reinforced sheet are corresponding up and down with the position of the anti-rotation sheet body of anti-rotation sheet and anti-rotation spacing hole, described elastic ring is provided with at least two, each elastic ring is arranged in below the reinforcement spacing hole of reinforced sheet.
Preferred as one, three groups of plectrums are that y-type structure is arranged, the angle between three limits of three groups of plectrums that y-type structure is arranged is respectively 75 °, 150 ° and 135 °.
Preferred as one, the inner ring of elastic ring is upwards provided with a circle flange.
Compared with prior art, the beneficial effects of the utility model are:
The utility model compound seal antivibration anti-rotation sheet is used in below hex head bolt, for the hex head bolt that the hex head bolt of Anti-rotating grommet or prefastening torque can not be used not to implement on request provides anti-rotating function, and can be used in the position of seal request.Compound seal antivibration anti-rotation sheet strong operability, improve some functor (as roof exhaust emission device, junction box etc.) fastening after safety and reliability.Therefore this compound seal antivibration anti-rotation sheet has that tools for bolts ' pretension moment of torsion can be made to reach requirement is non-maintaining, and Long-Time Service can not produce the advantage of seal failure.
