Magnetic piece suction together, offers the stationary ring O-ring being contained in groove one on the outer shroud of the stationary ring, the stationary ring O-ring it is straight
Footpath offers the rotating ring O-ring being contained in groove two more than the depth of groove one on the internal ring of the rotating ring, the rotating ring 0 is enclosed
The depth with diameter greater than groove two, the longitudinal cross-section of the stationary ring and rotating ring is the notch cuttype fitted each other, the tread of ladder
Contact surface is cambered surface；
The low order face of the stationary ring is provided with the groove three of accommodating permanent magnets, and permanent magnets are cambered surface with the contact surface of rotating ring；
The low order face of the rotating ring is provided with the groove four of accommodating modified tetrafluoro body, and the modified tetrafluoro body portion is contained in
In groove four, partly it is located on the outer terrace of groove four, the modified tetrafluoro body is cambered surface with the contact surface of stationary ring.
The riser of the ladder that the rotating ring is contacted with stationary ring is provided with the groove five of accommodating spacing 0 circle, spacing 0 circle
With diameter greater than the depth of groove five；
The riser that the stationary ring is contacted with rotating ring is provided with snap ring, and the lateral surface of the snap ring is cambered surface, and medial surface is straight
Face.
The snap ring includes the circular arc block of some equal portions, and bottom and the stage clip of each circular arc block are connected in rotating ring.
The beneficial effects of the utility model are：There is the cancave cambered surface friction of convex globoidal and stationary ring in the front of modified tetrafluoro body, close
Envelope effect is good, even if existed in the course of the work by axle perturbing, modified that contact surface is still had between tetrafluoro body and stationary ring, protects
It is QED hermetically sealed, effectively prevent from leaking at sealing, extend the life-span of sealing device；Limited location snap ring is divided into into some equal portions and is utilized
The effect of stage clip is spliced into entirety, is easy to rotating ring is installed on stationary ring.
Description of the drawings
Fig. 1 is structural representation of the present utility model；
In figure, 1 is stationary ring, and 11 is groove one, and 12 is stationary ring O-ring, and 13 is snap ring, and 2 is rotating ring, and 21 is groove two, 22 rotating rings
0 circle, 23 is spacing 0 circle, 24 grooves five for being, 3 is permanent magnets, and 4 is modified tetrafluoro body.
Specific embodiment
Below in conjunction with the accompanying drawings this utility model is illustrated.
As shown in figure 1, this utility model includes copper stationary ring 1, rustless steel brake hoop 2 and permanent magnets 3,1 He of the stationary ring
The rotating ring 2 together, offers the stationary ring O being contained in groove 1 by 3 suction of permanent magnets on the outer shroud of the stationary ring 1
Circle 12, the depth with diameter greater than groove 1 of the stationary ring O-ring 12 is offered on the internal ring of the rotating ring 2 and is contained in groove
Rotating ring O-ring 22 in 2 21, the rotating ring 0 enclose the vertical of 22 depth with diameter greater than groove 2 21, the stationary ring 1 and rotating ring 2
It is the notch cuttype fitted each other to section, the tread contact surface of ladder is cambered surface；
The low order face of the stationary ring 1 is provided with the groove three of accommodating permanent magnets 3, and permanent magnets 3 are arc with the contact surface of rotating ring 2
Face；Cambered surface contact area is big, and good sealing effect, even if having received external force pressure, still has contact surface between the two, effectively prevents close
Leak at envelope, extend the life-span of sealing device.
