Description
Technical Field
The utility model relates to a three station isolator stop device belongs to the electrical equipment field.
Background
The three-position isolating switch is an important component applied to GIS combined electrical equipment, the total rotating angle of the three-position isolating switch is usually larger than 360 degrees, and the conditions that the opening and closing positions are inaccurate and even a contact exceeds a preset position often exist in the actual work. A three-position isolating switch's spacing operating means of flexible pin is introduced in public patent No. CN108987170A, and its problem lies in that effective spacing angle is little, and overall structure can not surpass 360, and spacing pin accomplishes spacing action after, just can carry out next operation after needing the manual operation to reset. A disconnecting switch opening and closing limiting device is introduced in the patent publication No. CN201369266Y, the structure of the disconnecting switch opening and closing limiting device is not easy to miniaturize, and the effective rotating angle can not exceed 360 degrees.
Disclosure of Invention
The to-be-solved technical problem of the utility model is: how to solve three station isolator corners and can not exceed 360 degrees the problem, how to simplify isolator's structure.
In order to solve the technical problem, the technical scheme of the utility model a three station isolator stop device is provided, a serial communication port, including fixed axle sleeve, fixed axle sleeve sets up on switch housing, fixed axle sleeve inside is equipped with sealing member and bearing, the sealing member is connected with the bearing and is formed air-tightly, the side and the mounting flange of fixed axle sleeve are connected, mounting flange and flange joint rotate, at mounting flange and the ditch inslot that flange joint rotated the formation be equipped with the restriction and rotate flange and fix flange turned angle's steel ball, the flange that rotates passes through spacing pin to be fixed in the outside of axis of rotation.
Preferably, the inner side of the fixed sleeve is fixed on the outer side of the rotating shaft through a bearing.
Preferably, the fixed flange is provided with a plurality of limiting pins.
Preferably, the rotating flange is fixed outside the rotating shaft.
Preferably, the rotating shaft is connected with the sealing element to form an airtight seal.
The utility model has the characteristics of have: the limiting structure is compact, the whole component can be arranged in the range not exceeding the thickness of the fixed flange, the rotating flange is connected with the rotating shaft in a hexagonal matching mode, the rotating flange is fixed on the rotating shaft in the axial direction by using the limiting pin, and grooves for rolling the steel balls are formed in the outer ring of the rotating flange and the inner side of the fixed flange. Two limit pin installation positions are arranged on the outer side of the fixed flange, and limit pins are installed in the two limit pin installation positions. When the rotating shaft rotates, the limiting pin on the rotating flange pushes the steel ball to slide in the groove between the fixed flange and the rotating flange until the steel ball slides to the limiting pin on the fixed flange, limiting is effective, and when the steel ball rotates reversely, the steel ball is pushed to the other limiting pin, so that the forward and reverse limiting function of the rotating shaft is realized.

Detailed Description
In order to make the present invention more comprehensible, preferred embodiments are described in detail below with reference to the accompanying drawings.
As shown in fig. 1 to 4, a three-station disconnecting switch limiting device is characterized by comprising a fixed shaft sleeve 8, wherein the fixed shaft sleeve 8 is arranged on a switch shell, a sealing element 7 and a bearing 6 are arranged inside the fixed shaft sleeve 8, the sealing element 7 is connected with the bearing 6 to form an airtight seal, the side surface of the fixed shaft sleeve 8 is connected with a fixed flange 1, the fixed flange 1 is connected with a rotating flange 2, steel balls 5 for limiting the rotating angle of the rotating flange 2 and the fixed flange 1 are arranged in a groove formed by connecting the fixed flange 1 with the rotating flange 2, and the rotating flange 2 is fixed outside a rotating shaft 4 through a limiting pin 3.
The working principle is that the ball 5 arranged between the fixed flange 1 and the rotating flange 2 is utilized to limit the rotating shaft 4 to continue rotating at a preset angle position, so that the preset limiting function is realized, the effective working angle can be set according to the actual requirement, and the rotating angle is larger than 360 degrees.
As shown in fig. 1, the rotating flange 2 is fixed to the outside of the rotating shaft 4 using a stopper pin 3. The fixed flange 1 is mounted on the fixed shaft sleeve 8. The sealing element 7 and the bearing 6 are assembled in the fixed shaft sleeve, so that the assembled structure has a rotary airtight function. The steel ball 5 is arranged in a groove formed by the fixed flange 1 and the rotating flange 2, and can freely slide in the groove.
As shown in fig. 1 and 2, two limit pins 9 are mounted on the fixed flange 1, and the steel ball 5 can freely slide in a groove formed by the fixed flange 1 and the rotating flange 2.
As shown in fig. 1 and 3, the rotating shaft 4 rotates counterclockwise, the limit pin 3 pushes the steel ball 5 to slide to the limit pin 9 fixed on one side of the fixed flange 1, and at this time, due to the limitation of the steel ball 5, the limit pin 3 and the limit pin 9, the rotating shaft 4 cannot rotate any more, and is limited to stop at a set angular position.
As shown in fig. 1 and 4, the rotating shaft 4 rotates clockwise, the limit pin 3 pushes the steel ball 5 to slide to the limit pin 9 fixed on one side of the fixed flange 1, and at this time, due to the limitation of the steel ball 5, the limit pin 3 and the limit pin 9, the rotating shaft 4 can not rotate any more and is limited to stop at a set angle position.
