Side, and compress attached article.Threaded hole both ends are respectively arranged with sealing ring and flange ring, seal ring displacement bolt thread section and
Between nut body, one end of threaded hole is sealed, flange ring surface area is larger, in such a way that large area pushes against contact, increases
The waterproof performance of strong another section of nut body, to effectively improve the waterproof performance of the utility model.
Further, the nut body is integrally fixed with increasing far from one end side of the flange ring in the threaded hole
Qiang Huan.
Through the above technical solutions, setting enhancing ring is used to improve the structural strength of the utility model threaded hole one end.
Further, the enhancing ring inner wall circumferentially offers the clamping groove for being clamped the sealing ring.
Through the above technical solutions, opening up clamping groove for being clamped sealing ring, sealing ring is fixed.
Further, the sealing ring side wall is circumferentially provided with multiple fixture blocks, the clamping groove inner wall offer with it is described
The card slot that fixture block is engaged by clamping.
Through the above technical solutions, sealing ring is fixed in clamping groove using the clamping engagement between fixture block and card slot,
It avoids sealing ring from rotating coaxially in clamping groove, causes sealing ring that can not screw on bolt.
Further, it is offered on the enhancing ring and multiple turns slot convenient for turn the nut body.
Through the above technical solutions, in use, nut body can be turned using with multiple mating tools of slot that turn,
Nut body is screwed off from bolt.
Further, the thickness of the flange ring gradually becomes smaller along the direction far from its axis.
Through the above technical solutions, the pressure in flange ring can be transferred uniformly into the position at flange ring edge.
Further, the sealing ring inner wall circumferentially offers thread groove.
Through the above technical solutions, thread groove connect convenient for sealing ring with bolt thread, to improve sealing performance.
Further, the nut body is made of stainless steel.
Through the above technical solutions, making nut using stainless steel, the rustless property of nut can be effectively improved.
Compared with prior art, the utility model has the beneficial effects that
(1) by the way that sealing ring and flange ring is respectively set at nut both ends, be utilized respectively sealing blocking and increases bearing surface
Principle, enhance threaded hole both ends sealing performance；
(2) further, enhance ring by integrally fixed on nut body, improve the structure at threaded hole place open at one end
Intensity；
(3) further, slot is turned by opening up on enhancing ring, increase turns the mode for screwing off nut body, is convenient for
It will turn and screw off nut.

Specific embodiment
In order to keep the purpose of this utility model, technical scheme and beneficial effects clearer, below with reference to embodiment and attached
The utility model is described in further detail for figure, but the embodiments of the present invention is not limited only to this.
As depicted in figs. 1 and 2, a kind of flange nut, the nut body 1 including regular hexagonal prism shape, nut body 1 is not using
Rust steel is made, and for ensuring that the utility model has good rustless property, runs through on nut body 1 and offers threaded hole 2, spiral shell
Clamping is connected with sealing ring 3 in 2 one end of pit, and sealing ring 3 is made of rubber, and 3 inner wall of sealing ring offers thread groove 10, spiral shell
Groove 10 is identical as the screw thread model of threaded hole 2, connect convenient for sealing ring 3 with bolt thread.
Side of the nut body 1 far from sealing ring 3 is integrally coaxially fixed with flange ring 4, for increasing nut body 1 in even
The contact area between object is connect, to improve the barrier performance of this practical confidence, the thickness of flange ring 4 is along its separate axis
