Abstract
A kind of sealing nut, include nut, described nut middle part is provided with the screwed hole of non-up/down perforation, described nut upper side is provided with a rectangle annular groove around screwed hole its periphery, a sealing ring is provided with described rectangle annular groove, the inside and outside side face of the sealing ring is slope structure so as to form up-small and down-big trapezoidal sealing ring with following face on sealing ring;Vertical height vertical depth more than rectangle annular groove of the sealing ring top face to following face.
Description
Technical field
The invention belongs to mechanical workpieces field, it is related to a kind of nut, more particularly to a kind of sealing nut.
Background technology
Conventional screw cap in itself without sealing function, when in use to play sealing effectiveness often in nut and absorption surface
One sealing ring is set to play sealing effectiveness, this kind of encapsulating method is generally used on conventional equipment on face, but space flight work
Part, equipment are high to tightness requirement, and stability after being tightened to nut have it is very high to go, the side of traditional pad sealing ring
Method, will between sealing ring weathering rear nut and workpiece in the easily aging and weathering of exceedingly odious environmental condition lower sealing ring
Form gap, therefore the tightness of nut can be affected and even result in nut and loosen until come off.
The content of the invention
It is an object of the invention to overcome the deficiencies in the prior art, and provide a kind of simple structure, good sealing effect it is close
Envelope nut.
Technical scheme is as follows:
A kind of sealing nut, includes nut, and described nut middle part is provided with the screwed hole of non-up/down perforation, described nut
Upper side is provided with a rectangle annular groove around screwed hole its periphery, and a sealing ring, institute are provided with described rectangle annular groove
The inside and outside side face for stating sealing ring is slope structure so as to form up-small and down-big trapezoidal sealing ring with following face on sealing ring;
Vertical height vertical depth more than rectangle annular groove of the sealing ring top face to following face.
The invention has the advantages that:The rectangle annular groove set around screwed hole its periphery in nut upper side is not
Can be only used for accommodating sealing ring, and sealing ring can be positioned.Sealing ring uses up-small and down-big trapezoidal sealing ring
Make sealing ring inside and outside while face and rectangle annular groove it is inside and outside while face between be respectively formed a triangular space annular groove, in tightening nuts
Sealing ring is extruded, and triangular space annular groove is gradually filled in the part expanded during sealing ring is extruded and produces deformation, and
The problem that rectangle annular groove is overflowed in deformation process will not be produced, therefore will not pad between nut and workpiece when nut is tightened
Sealing ring, but identical or better seal effect can be played.Sealing ring is compressed in rectangular channel and produces one with external environment
Determine the isolation of degree, so that sealing ring will not be subject to the direct invasion of adverse circumstances, substantially prolongs the life-span of sealing ring.
Brief description of the drawings
Fig. 1 is overall cross section structure diagram of the invention.
Fig. 2 is cross section structure diagram of the nut when sealing ring is not installed.
Fig. 3 is overlooking the structure diagram of the nut when sealing ring is not installed.
Fig. 4 is seal ring structure schematic diagram.
In figure:1st, nut 2, screwed hole 3, rectangle annular groove 4, sealing ring.
Specific embodiment
Technical scheme is described further with reference to embodiment.
Embodiment 1
As shown in Fig. 1-4, a kind of sealing nut includes nut 1, and the described middle part of nut 1 is provided with the spiral shell of non-up/down perforation
Pit 2, the described upper side of nut 1 is provided with a rectangle annular groove 3 around its periphery of screwed hole 2, in described rectangle annular groove 3
A sealing ring 4 is provided with, the inside and outside side face of the sealing ring 4 is slope structure so as to be formed with following face on sealing ring 4
Up-small and down-big trapezoidal sealing ring;
Vertical height vertical depth more than rectangle annular groove 3 of the top face of the sealing ring 4 to following face.
The present invention is when in use:Sealing ring is put into the rectangle annular groove of nut first, then tightening nuts, what is tightened
During the top face of sealing ring first contacted with workpiece, sealing ring is constantly deformed during nut is further tightened
Expansion, its dilation is filled into the spatial band between sealing ring and rectangle annular groove, is tightened to up to after tightness requirement in nut
Sealing ring is pressed in rectangle annular groove completely.
