Abstract
The utility model relates to a pivot rotating accessory, include the dynamic seal axle core and center on the bearing frame of dynamic seal axle core periphery, the inner wall intermediate position of bearing frame be equipped with the boss, the boss extend towards the axle center of bearing frame, the outer wall of bearing frame be the step shape, the bearing frame backstop portion and connecting portion have, connecting portion pass the panel via hole of the cabinet body, backstop portion and panel laminating, follow the boss start, set gradually lip seal circle and deep groove ball bearing to two outer ends along the axle center, a terminal surface of dynamic seal axle core on be equipped with the turning handle, the turning handle be used for with operating device's output shaft. Through the arrangement of the deep groove ball bearing of the lip-shaped sealing ring, the air tightness is enhanced, and meanwhile, the rotating effect is not influenced, so that the opening and closing actions of the operating mechanism are stable and smooth.
Description
Technical Field
The utility model relates to a pivot rotating accessory.
Background
The rotating accessory is always needed on the isolation panel to realize the connection of the output shaft of the operating mechanism and the rotary driving mechanism, the traditional rotating accessory of the rotating shaft is only provided with a shaft sleeve on the panel, and the output shaft is arranged in the shaft sleeve in a penetrating way, and the structure has the defects that: because the output shaft and the axle center of the rotary driving mechanism may have deviation during assembly, the shaft sleeve is easily extruded during the rotation process, and the effect is influenced. In addition, simple shaft sleeve treatment also causes the leakage of gas in the gas-filled cabinet easily.
Disclosure of Invention
In view of this, the present invention provides a rotating shaft rotating accessory with simple structure, good air tightness, and smooth rotation.
In order to realize above mesh, this practicality adopts such pivot rotating accessory, including the dynamic seal axle core and around the bearing frame of dynamic seal axle core periphery, the inner wall intermediate position of bearing frame be equipped with the boss, the boss extend towards the axle center of bearing frame, the outer wall of bearing frame be the step, the bearing frame backstop portion and connecting portion have, connecting portion pass the panel via hole of the cabinet body, backstop portion and panel laminating, follow the boss start, set gradually lip seal and deep groove ball bearing to two outer ends along the axle center, a terminal surface of dynamic seal axle core on be equipped with the turning handle, the turning handle be used for with operating device's output shaft. Compared with the prior art, the invention has the beneficial technical effects that: through the arrangement of the deep groove ball bearing of the lip-shaped sealing ring, the air tightness is enhanced, and meanwhile, the rotating effect is not influenced, so that the opening and closing actions of the operating mechanism are stable and smooth.
In particular, a groove is arranged on the plane where the stopping part is attached to the panel, and an O-shaped sealing ring is placed in the groove. By the arrangement of the structure, the air tightness can be further improved.
Particularly, the connecting part is provided with an embedding hole, the diameter of the bottom of the embedding hole is larger than that of the port of the embedding hole, and the inner wall of the connecting part is uniformly provided with V-shaped grooves along the axis direction. Through the setting of above structure, rotary drive mechanism's pivot can form the meshing with the V-arrangement groove for rotation efficiency improves, and the bottom diameter in embedding hole is great, makes things convenient for the light insertion embedding hole of pivot, the assembly of being convenient for.
Drawings
FIG. 1 is a perspective view of an embodiment of the present invention;
FIG. 2 is a cross-sectional view of an embodiment of the present invention;
fig. 3 is a bottom view of the dynamic seal shaft core in the embodiment of the present invention.
In the figure: 1. a dynamic seal shaft core; 11. a handle is rotated; 12. an insertion hole; 13. a V-shaped groove; 2. a bearing seat; 21. a boss; 22. a stopper portion; 3. a deep groove ball bearing; 4. a lip-shaped seal ring; 5. and an O-shaped sealing ring.
Detailed Description
As shown in fig. 1, 2, 3, a pivot rotating accessory, including the dynamic seal axle core 1 and around the bearing frame 2 in the dynamic seal axle core 1 periphery, the inner wall intermediate position of bearing frame 2 is equipped with boss 21, boss 21 extends towards the axle center of bearing frame 2, the outer wall of bearing frame 2 is the step, bearing frame 2 has backstop portion 22 and connecting portion, connecting portion pass the panel via hole of the cabinet body, backstop portion 22 and panel laminating, set gradually lip seal 4 and deep groove ball bearing 3 to two outer ends along the axle center from boss 21, be equipped with turning handle 11 on the terminal surface of dynamic seal axle core 1, turning handle 11 is used for being connected with operating device's output shaft.
The plane of the stopping part 22 attached to the panel is provided with a groove, and an O-shaped sealing ring 5 is placed in the groove.
The connecting part is provided with an embedding hole 12, the diameter of the bottom of the embedding hole 12 is larger than that of the end port of the embedding hole 12, and the inner wall of the connecting part is uniformly provided with V-shaped grooves 13 along the axis direction.
