Abstract
The utility model discloses a rotating arm support for an isolation switch, which comprises a conical supporting cylinder and a bracket, wherein the bracket is formed by an upper end flange plate and a lower end conical rotating body, the end part of the upper end of the conical supporting cylinder is provided with an annular bayonet, the bottom surface of the flange plate of the bracket is provided with a blocking cover surrounding the conical rotating body, the blocking cover is internally provided with a rotating ring which rotatably arranged at the outer wall of the root of the conical rotating body in a sleeved mode, the inner ring of the rotating ring is set to be an inclined wall matched with the outer wall surface of the conical rotating body, the lower end face of the rotating ring is provided with a ring slot matched with the annular bayonet of the conical supporting cylinder, and the bracket is matched with the annular bayonet through the rotating ring and rotatably arranged at the upper end of the conical supporting cylinder. The rotating arm support for the isolation switch is simple and reasonable in structure, convenient to install and use, good in stability and long in service life, the rotating component has good abrasion resistance and airtightness and less susceptible to abrasion influences after long use to result in reduction of the rotating operation stability of the rotating arm, the rotating operation is smooth and stable, and safe use of the isolation switch is effectively ensured.
Description
Technical field
The utility model relates to electric fittings field, is specially a kind of isolating switch rotating arm supporting base.
Background technology
Isolating switch is the switching device often using in power equipment, and the turntable base structure of existing isolating switch is reasonable not, stability and durability are poor, useful life is shorter, easily wearing and tearing between pivoted arm and bearing after long-time use, and then cause pivoted arm stability of rotation to decline, rotating operation bite, easily there is deviation, crooked phenomenon, affect the safe handling of isolating switch.
Utility model content
The purpose of this utility model is to provide a kind of isolating switch rotating arm supporting base, turntable base structure with isolating switch traditional in solution prior art is reasonable not, stability and durability are poor, useful life is shorter, easily wearing and tearing between pivoted arm and bearing after long-time use, and then cause pivoted arm stability of rotation to decline, rotating operation bite, easily there is deviation, crooked phenomenon, affect the problem of isolating switch safe handling.
For achieving the above object, the technical solution adopted in the utility model is:
A kind of isolating switch rotating arm supporting base, it is characterized in that: include taper holder cylinder and bracket, described bracket is turned and is formed by upper flanges dish and lower end toper, end, described taper holder cylinder upper end is provided with annular bayonet socket, turn and be provided with block cover around taper in the ring flange bottom surface of described bracket, in described block cover, be provided with to rotate and be nested with in the turn change of root outer wall of taper, described change inner ring is arranged to and the taper skew wall that outside wall surface fits of turning, described change lower surface is provided with the annular groove matching with the annular bayonet socket of taper holder cylinder, described bracket matches with annular bayonet socket by change to rotate to hold in the palm and puts in taper holder cylinder upper end.
Described a kind of isolating switch rotating arm supporting base, is characterized in that: described taper holder cylinder upper end outer wall is provided with the block plate of outside extension.
The beneficial effects of the utility model are:
The utility model is simple and reasonable, easy to install, stability is good, long service life, rotatable parts have good resistance to wear and sealing, after long-time use, be also difficult for frayed impact and cause the rotating operation stability decreases of pivoted arm, rotating operation is smooth stable, has effectively ensured the safe handling of isolating switch.
