Abstract
The utility model relates to the technical field of air charging cabinets, in particular to a dynamic sealing structure of an air charging cabinet, comprising a dynamic fit base, a dynamic fit shaft sleeve and a dynamic fit shaft, wherein one end of the dynamic fit shaft is fixed at the dynamic fit base; the dynamic fit shaft sleeve is sheathed on the dynamic fit shaft; and the dynamic shaft sleeve and the dynamic fit shaft are sealed through a magnetic fluid bearing. The arrangement of the magnetic fluid bearing between the dynamic fit shaft sleeve and the dynamic fit shaft achieves the effect of permanent sealing between the dynamic fit shaft sleeve and the dynamic fit shaft.
Description
Technical field
The utility model relates to inflation cabinet technical field, particularly a kind of movable sealing structure of inflating cabinet.
Background technology
Inflation cabinet movable sealing structure generally is installed between load switch body and the operating mechanism, its inner switch rotating spindle that connects, cam at the bottom of the outside attended operation mechanism drive plate.Because on-load switch inside has been full of gas, thus must adopt movable sealing to cooperate in the junction,
Existing inflation cabinet movable sealing structure comprises movingly base, axle sleeve and axle movingly movingly, base has installing hole movingly, Zhou a end and the installing hole assembling and the welding of base movingly movingly, axle sleeve is sleeved on movingly on the axle movingly, movingly axle sleeve and between the axle interior fitted bearing is set movingly.The deficiency of this structure be bearing movingly and movingly the sealing effectiveness of the interior fitted bearing between the axle be not enough ideals, and can wear out.
The utility model content
Technical problem to be solved in the utility model is: provide a kind of sealing effectiveness better, more can increase the movable sealing structure of the inflation cabinet in useful life.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of movable sealing structure of inflating cabinet, comprise movingly base, axle sleeve and axle movingly movingly, Zhou a end is fixed with base movingly movingly, axle sleeve is sleeved on movingly on the axle movingly, movingly axle sleeve and sealing by magnetic fluid bearing between the axle movingly.
The endoporus of axle sleeve has ring-shaped step movingly, and the two ends of ring-shaped step all have magnetic fluid bearing; The periphery of axle sleeve has external screw thread movingly, and the periphery of axle sleeve has annular boss movingly, has annular groove on the step surface of annular boss, has sealing ring in the annular groove.
Zhou a end has axial blind hole movingly.
Has circular hole on the base movingly.
Base and have plastic washer movingly between the axle sleeve movingly.
The beneficial effects of the utility model are: at axle sleeve movingly with between the axle magnetic fluid bearing is set movingly, reached the axle sleeve and the effect of the permanent seal between the axle movingly movingly.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified;
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the A-A full sectional view of Fig. 1;
Among the figure, 1. base movingly, 1-1. circular hole, 2. axle sleeve movingly, 2-1. ring-shaped step, 2-2. magnetic fluid bearing, 2-3. annular boss, 2-3-1. annular groove, 3. axle movingly, 3-1. axial blind hole, 4. sealing ring, 5. plastic washer.
Embodiment
Shown in Fig. 1,2, a kind of movable sealing structure of inflating cabinet comprises movingly base 1, axle sleeve 2 and axle 3 movingly movingly, and an end of axle 3 is with base 1 is fixing movingly movingly, and axle sleeve 2 is sleeved on movingly on the axle 3 movingly.The endoporus of axle sleeve 2 has ring-shaped step 2-1 movingly, and the two ends of ring-shaped step 2-1 all have magnetic fluid bearing 2-2.The periphery of axle sleeve 2 has external screw thread movingly, and the periphery of axle sleeve 2 has annular boss 2-3 movingly, has annular groove 2-3-1 on the step surface of annular boss 2-3, has sealing ring 4 in the annular groove 2-3-1.When assembling, the utility model is fixed in the cabinet with the mode that is threaded, in the process that screws, the sealing ring in the annular groove 2-3-1 4 is oppressed, reach the effect of sealing.
Referring to Fig. 1, shown in 2, the utility model in use, the inflation cabinet generally is divided into two cabinets, fitting operation mechanism in the cabinet, in another cabinet on-load switch is installed, and gassy, have installing hole between two cabinets, after the movable sealing structure of this inflation cabinet has welded movable sealing base 1 and movable sealing axle 3, be sleeved in the installing hole of cabinet, the on-load switch main shaft is installed on the circular hole 1-1 on the base 1 movingly, and operating mechanism is installed among the axial blind hole 3-1 of axle 3 movingly, reaches operating operation mechanism and controls the on-load switch branch, the effect of closing a floodgate.In order to improve sealing effectiveness, described base movingly 1 and have plastic washer 5 movingly between the axle sleeve 2.
