Description
Technical field
The utility model relates to a kind of air seal technical field, particularly a kind of inflation cabinet gas sealing structure.
Background technology
At present, existing 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, so must adopt movable sealing to cooperate in the junction, two effects are mainly played in this movable sealing, and the main shaft of first connection switch inside makes operating mechanism can drive internal spindle and rotates, and switch is just realized dividing, closing a floodgate; Second makes connecting portion air tight.Existing inflation cabinet movable sealing structure adopts labyrinth seal, to reach the purpose that prevents gas leak, labyrinth seal is because complex structure, implement the comparison difficulty, and sealing effectiveness is undesirable, skeleton sealing then is solid-affixed touch sealing, and solid friction is easy to cause seal fails, shortens switch useful life.
The purpose of this utility model is to provide a kind of good sealing effect, increases the inflation cabinet movable sealing structure in useful life.
In order to achieve the above object, the technical solution of the utility model is:
A kind of inflation cabinet movable sealing structure, comprise 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, the endoporus of described axle sleeve movingly has ring-shaped step, and the two ends of ring-shaped step all have interior fitted bearing; The periphery of described axle sleeve movingly has external screw thread, 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.
A described end of axle movingly has axial blind hole.
Has circular hole on the described base movingly.
Described base movingly and have plastic washer movingly between the axle sleeve.
The outer face of fitted bearing has dust ring in described.
After adopting said structure, because the endoporus of axle sleeve movingly of the present utility model has ring-shaped step, the two ends of ring-shaped step have interior fitted bearing, therefore two interior fitted bearings and ring-shaped step tight fit, reduced the friction of movable sealing axle sleeve and movable sealing axle, improved stability of rotation, so also increase useful life greatly; There is the periphery of described axle sleeve movingly to have external screw thread again, 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, therefore 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 is oppressed, promptly solved the gas leakage problem after acquiring a certain degree, so the utility model sealing effectiveness improves greatly.
Description of drawings
Fig. 1 is the structural representation of the utility model inflation cabinet movable sealing structure;
Fig. 2 is the A-A full sectional view of Fig. 1.
Embodiment
The embodiment that provides below in conjunction with accompanying drawing is described in further detail the utility model.
Shown in Fig. 1,2, a kind of inflation cabinet movable sealing structure of the present utility model, comprise movingly base 1, axle sleeve 2 and axle 3 movingly movingly, base 1 has installing hole 1-1 movingly, an end of axle 3 and the installing hole 1-1 assembling and the welding of base 1 movingly movingly, axle sleeve 2 is sleeved on movingly on the axle 3 movingly, and the endoporus of described axle sleeve movingly 2 has ring-shaped step 2-1, and the two ends of ring-shaped step 2-1 all have interior fitted bearing 2-2; The periphery of described axle sleeve movingly 2 has external screw thread, 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.
Shown in Fig. 1,2, for the on-load switch main shaft is installed, realize on-load switch branch, combined floodgate, a described end of axle 3 movingly has axial blind hole 3-1.
Shown in Fig. 1,2,, has circular hole 1-1 on the described base movingly 1 for attended operation mechanism.
Shown in Fig. 1,2, in order to improve sealing effectiveness, described base movingly 1 and have plastic washer 5 movingly between the axle sleeve 2.
Shown in Fig. 1,2, in order to enter dust among the fitted bearing 2-1 in preventing, influence is rotated, and the outer face of described interior fitted bearing 2-1 has dust ring 2-4.
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 utility model inflation cabinet movable sealing structure 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, operating mechanism is installed in movingly among the axial blind hole 3-1 of axle 3, reaches the effect that operating operation mechanism controls on-load switch branch, combined floodgate.The utility model good sealing effect, also increase greatly useful life.
