On described connecting element, fastener is installed, described fastener is provided with at least two junction buttons, described in adjacent two, junction button is rotatably installed in together, on described junction button away from one end of described fastener, be connected with fixing chain, the other end of described fixing chain is provided with for being fixedly mounted on the fixed element in described urea tank;
Described sealing cover body is provided with annular groove near a side of described filler, in described annular groove, be provided with the obstruction identical with described sealing cover body bearing of trend, one end near described annular groove in described obstruction is provided with an annular protrusion, between described annular protrusion and described obstruction, be provided with the first sealing gasket, the outside of described the first sealing gasket is provided with the breach identical with described the first sealing gasket bearing of trend; The middle part of described obstruction be provided with protrude described obstruction and with the suitable screw thread of the base of described filler;
Described obstruction is provided with projection away from one end of described sealing cover body, is installed with the second sealing gasket on described projection, described the second sealing gasket away from one end of described projection be provided with protrude described the second sealing gasket and with the suitable boss of the filling neck of described filler.
Improve as one, the inside of described obstruction is provided with hollow groove, and the bearing of trend of described hollow groove is consistent with the bearing of trend of described obstruction.
As further improvement, the described obstruction that is positioned at described hollow groove is provided with supporting post, and the upper surface of described supporting post is concordant with the upper surface of described obstruction.
Owing to having adopted technique scheme, the beneficial effects of the utility model are:
Be rotatably installed in junction button together because fastener is provided with, thus at sealing cover body in the time tightening or screw out filler base, junction button is rotation simultaneously also, makes sealing cover body and fixing chain that wrapping phenomena not occur, not only attractive in appearance, and easy to operate; Be with reeded connecting element owing to being injected with in projection, thereby increased join strength, effectively ensured the reliability that sealing cover body is connected with fixing chain; Be provided with the first sealing gasket and the second sealing gasket owing to stopping up, realize double sealing structure, be aided with simultaneously the screw thread suitable with filler base and with the suitable boss of filling neck, greatly improve sealability, avoid the urea liquid in urea tank easily to ooze out, the problem of other component on corrosion automobile and automobile, and reduced waste and economic loss; Because the first sealing gasket is provided with breach, thereby by the opening and retract of breach, realize Flexible change, reached the reliability that the first sealing gasket contacts with filler, further ensured sealing.
Because the inside of stopping up is provided with hollow groove, thereby effectively alleviate obstruction weight, prevented stopping up weight excessive, in use because deadweight comes off.
Because the obstruction in hollow groove is provided with supporting post, thereby improve the join strength stopping up with the second sealing gasket place by supporting post.
