Description
Technical field
The utility model belongs to technical field of fastening, refers in particular to a kind of flange Ball faced nut.
Background technique
Nut is a kind of connector being used cooperatively with bolt, and external screw thread is had on bolt, has internal screw thread, spiral shell on nut
Screw bolt and nut is used to be fastenedly connected two parts for having through-hole, and this type of attachment claims to be bolted, but existing nut makes
Following problems are primarily present in: the threaded connection place easy-to-rust of nut and bolt influences to dismantle；It can go out between nut and bolt
Now loosen；There is sealing function between through-hole on particularly important nut and part.
Utility model content
The purpose of the utility model is to provide a kind of stable connections, the flange Ball faced nut of good airproof performance.
Purpose of the utility model is realized as follows: a kind of flange Ball faced nut, including nut body, on nut body
Equipped with internal thread hole, it is characterised in that: one end of the nut body is equipped with flange ring, and flange ring deviates from the one of nut body
It is additionally provided with sealing ring on side, the periphery wall of sealing ring is spherical, is additionally provided on flange ring and is placed in sealing ring and connect with flange ring
Stress slot in place, is additionally provided with the fastener hole being connected to internal thread hole on the periphery wall of nut body, on internal thread hole inner wall also
Equipped with the oil storage annular groove being connected to fastener hole, the pin for fastening is equipped in fastener hole.
By using above-mentioned technical proposal, spherical can be contradicted with the aperture on fixture, realize the hard leakproofness of spherical surface,
To improve leakproofness, after locking, the periphery wall of sealing ring is main stress point, the periphery wall and flange ring table of sealing ring
The junction in face will form stress concentration region, by opening up for stress slot, stress can be dispersed in stress slot, play dispersion
The effect of stress, can be by fastener hole to storage when nut body is next with bolt lock so that it is guaranteed that the structural strength of its junction
Oiling in oil ring groove, lubricating oil are permeable between screw thread, both can guarantee lubricity between nut body and bolt, have been played antirust
Effect, and be able to achieve oil sealing, pin is threadedly coupled with fastener hole, plays the role of closure to oil storage annular groove by pin, again
Dowel ends and bolt can be made to contradict by safetied pin, effect fixed on axis is played to bolt, avoid nut and bolt it
Between generate loosening.
The utility model is further arranged to: seal washer is equipped in the stress slot.
By using above-mentioned technical proposal, the leakproofness after connection is further increased by the setting of seal washer.
The utility model is further arranged to: by inclining between the periphery wall of the nut body and the periphery wall of flange ring
The transition face connection being tiltedly arranged.
By using above-mentioned technical proposal, the setting of transition face, so that the periphery of the periphery wall of nut body and flange ring
Have the function of skewed horizontal load between wall, the stress intensity between threaded body and flange ring can be improved.
The utility model is further arranged to: the outer surface of the nut body is equipped with coating.
By using above-mentioned technical proposal, coating can increase the corrosion and wear resistance wearability of nut body outer surface.
Detailed description of the invention

Fig. 2 is the left view structural representation of the utility model Fig. 1；
Appended drawing reference in figure are as follows: 1, nut body；2, flange ring；3, sealing ring；4, spherical；5, stress slot；6, it fastens
Hole；7, oil storage annular groove；8, pin；9, transition face.
Specific embodiment
The utility model is further described with specific embodiment with reference to the accompanying drawing, referring to Fig. 1-2:
A kind of flange Ball faced nut, including nut body 1, nut body 1 are equipped with internal thread hole, it is characterised in that: institute
The one end for stating nut body 1 is equipped with flange ring 2, and flange ring 2 is additionally provided with sealing ring 3 on the side of nut body 1, seals
The periphery wall of ring 3 is spherical 4, and the stress slot 5 being placed on sealing ring 3 and 2 junction of flange ring, spiral shell are additionally provided on flange ring 2
It is additionally provided with the fastener hole 6 being connected to internal thread hole on the periphery wall of maternal body 1, is additionally provided on internal thread hole inner wall and fastener hole 6
The oil storage annular groove 7 of connection, the interior pin 8 being equipped with for fastening of fastener hole 6.
By using above-mentioned technical proposal, spherical 4 can be contradicted with the aperture on fixture, realize that spherical surface seals firmly
Property, to improve leakproofness, after locking, the periphery wall of sealing ring 3 is main stress point, the periphery wall and method of sealing ring 3
The junction on blue 2 surface of ring will form stress concentration region, and by opening up for stress slot 5, stress can be dispersed to stress slot 5
It is interior, play the role of dispersive stress, so that it is guaranteed that the structural strength of its junction, when nut body 1 and bolt lock are next, can lead to
The oiling into oil storage annular groove 7 of fastener hole 6 is crossed, lubricating oil is permeable between screw thread, both can guarantee between nut body 1 and bolt
Lubricity plays the role of antirust, and is able to achieve oil sealing, and pin 8 is threadedly coupled with fastener hole 6, by pin 8 to oil storage annular groove
7 play the role of closure, and 8 end of pin and bolt can be made to contradict by safetied pin 8, and work fixed on axis is played to bolt
With, avoid between nut and bolt generate loosening.
The utility model is further arranged to: being equipped with seal washer in the stress slot 5.
