Abstract
The invention discloses a hexagonal sealing nut. The hexagonal sealing nut comprises an outer hexagonal body, wherein a threaded hole is formed in the center of the outer hexagonal body. The hexagonal sealing nut is characterized in that an upper annular groove is formed in the upper end surface of the outer hexagonal body and surrounds the threaded hole, an upper sealing ring is mounted in the upper annular groove in a buckled manner, the upper end surface of the upper sealing ring bulges out of the upper end surface of the outer hexagonal body, a lower annular groove is formed in the lower end surface of the outer hexagonal body and surrounds the threaded hole, a lower sealing ring is mounted in the lower annular groove in a buckled manner, and the lower end surface of the lower sealing ring bulges out of the lower end surface of the outer hexagonal body. The hexagonal sealing nut has good sealing performance after being mounted and screwed up.
Description
Technical field
The present invention relates to a kind of Fastener products, be specifically related to a kind of hexagon nut with sealing component.
Background technique
In the nut series of Fastener products, the consumption of hexagon nut is maximum.The hexagon nut of prior art, comprise the hexagon nut of band self-locking nylon, itself does not possess sealing function, hexagon nut after mounting its fastening end face (i.e. the lower end surface of hexagon nut) can also seal by arranging sealing gasket, the upper-end surface of hexagon nut then cannot seal, except non-usage cover type nut, and the application area of cover type nut is often very narrow.
Summary of the invention
In view of current known technology Problems existing, the technical problem to be solved in the present invention is to provide a kind of hexagonal sealing nut after installation screws with good seal performance.
The present invention implements by the following technical programs:
Hexagonal sealing nut, comprise outer-hexagonal body, tapped hole is established at outer-hexagonal body center, it is characterized in that: the upper-end surface of outer-hexagonal body arranges upper annular groove around tapped hole, spiral-lock upper sealing ring in upper annular groove, the upper-end surface of upper sealing ring protrudes from the upper-end surface of outer-hexagonal body, and the lower end surface of outer-hexagonal body arranges lower annular groove around tapped hole, spiral-lock lower sealing ring in lower annular groove, the lower end surface of lower sealing ring protrudes from the lower end surface of outer-hexagonal body.
The endoporus aperture of upper sealing ring is greater than tapped hole path and is less than the large footpath of tapped hole, and the endoporus aperture of lower sealing ring is more than or equal to the large footpath of tapped hole.
The groove top surrounding of upper annular groove is provided with turned welt, and upper turned welt is by upper sealing ring fastening in upper annular groove, and the groove top surrounding of lower annular groove is provided with lower turned welt, lower turned welt by lower sealing ring fastening in lower annular groove.
Adopt the hexagonal sealing nut of technique scheme, after fastening installation, lower sealing ring can be pressed on fastening end face, the sealing gasket in background technique is replaced to play the seal action of fastening end face (i.e. the lower end surface of hexagon nut), and bolt is when the endoporus through upper sealing ring, due to the resiliently deformable of Porous materials in upper sealing ring, the gap between the outside thread of bolt and the endoporus of upper sealing ring is also extruded disappearance, thus plays the seal action of hexagon nut upper-end surface; If use double nut also tight during fastening installation, the upper sealing ring of nut also can be compacted so below, better plays the seal action of hexagon nut upper-end surface (namely going up lower nut and tight end face).
Accompanying drawing explanation
The present invention has following accompanying drawing:
Fig. 1 is structural representation of the present invention,
Fig. 2 be Fig. 1 overlook directional diagram.
Embodiment
Details and the working principle of the specific embodiment of the invention is described in detail below in conjunction with accompanying drawing:
As shown in the figure, hexagonal sealing nut of the present invention, comprise outer-hexagonal body 1, tapped hole 2 is established at outer-hexagonal body 1 center, the upper-end surface of outer-hexagonal body 1 arranges upper annular groove around tapped hole 2, spiral-lock upper sealing ring 3 in upper annular groove, the groove top surrounding of upper annular groove is provided with turned welt 4, upper turned welt 4 by upper sealing ring 3 fastening in upper annular groove, the upper-end surface of upper sealing ring 3 protrudes from the upper-end surface of outer-hexagonal body 1, the lower end surface of outer-hexagonal body 1 arranges lower annular groove around tapped hole 2, spiral-lock lower sealing ring 5 in lower annular groove, the groove top surrounding of lower annular groove is provided with lower turned welt 6, lower turned welt 6 by lower sealing ring 5 fastening in lower annular groove, the lower end surface of lower sealing ring 5 protrudes from the lower end surface of outer-hexagonal body 1, upper-lower seal ring all adopts rubber material, the endoporus aperture of upper sealing ring 3 is greater than tapped hole 2 path but is less than the large footpath of tapped hole 2, and the endoporus aperture of lower sealing ring 5 is more than or equal to the large footpath of tapped hole 2.
