Abstract
The utility model relates to an automatic transfer switch with a positioning and locking mechanism. Primary and standby two execution breakers and a driving mechanism are fixed to a bottom seat; the driving mechanism comprises a motor, an installation plate, an incomplete toothed wheel and two slide blocks; the motor is fixed to the bottom seat; the incomplete toothed wheel is driven by a shaft of the motor and fixed to the installation plate; the two slide blocks are arranged on both sides of the incomplete toothed wheel and slide along a guide shaft fixed to the installation plate; teeth engaged with the incomplete toothed wheel, and bayonets combined with handles of the primary and standby two execution breakers are arranged on the slide blocks; positioning pins are arranged on the incomplete toothed wheel; positioning baffle pieces are arranged on the slide blocks. Because the positioning pins and the teeth move at the same angular velocity but in different radiuses, after the teeth and toothed racks are engaged, the slide blocks are pushed, the positioning pins and the positioning baffle pieces are separated, and the accurate engagement of the teeth and the toothed racks is ensured. In addition, because interlocking angles are arranged on the incomplete toothed wheel, rigid connection of the two slide blocks is realized, namely that mechanical interlocking is realized.
Description
Affiliated technical field
The utility model belongs to a kind of electric switch, particularly relates to a kind of automatic change-over that has position and lock mechanism.
Background technology
In the rack-and-pinion drive system of present known automatic change-over, the meshing point of tooth and perforation is a very crucial link, and the mechanical interlocked function that also is absolutely necessary in the automatic change-over, if handle bad this 2 point, gear can't accurately mesh with tooth bar, and automatic change-over can't be realized reliable transmission and operating of being perfectly safe.
The utility model content
The utility model provides a kind of automatic change-over that has position and lock mechanism for solving the technical problem that exists in the known technology.
The technical scheme that the utility model is taked for the technical problem that exists in the solution known technology is: it includes base, carry out circuit breaker and transmission mechanism for active and standby two, described active and standby two execution circuit breakers and transmission mechanism are fixed on the described base, and described transmission mechanism includes the motors that are fixed on the base and place two execution circuit breaker centres, be fixed on the mounting panel on the base, drive and be fixed on the partial gear on the described mounting panel and place described partial gear both sides and two slide blocks about be fixed on that guide shaft on the described mounting panel slides by the axle of described motor; On described slide block, have can with the tooth of partial gear engagement, and the bayonet socket that can combine with active and standby two handles of carrying out circuit breakers is arranged, on described partial gear, alignment pin is arranged, on described slide block, locating stop piece is arranged; Described alignment pin is the two ends of the horizontal diameter of partial gear when the partial gear left-right symmetric, described left and right sides locating stop piece be partial gear when the partial gear left-right symmetric horizontal diameter and described about the side that faces one another of two slide blocks when perpendicular, the place that joins with described alignment pin top on the slide block of the left and right sides.
The utility model can also adopt following technical measures:
Left-right symmetric two interlocking angles triangular in shape are arranged on described partial gear; A limit at two interlocking angles lays respectively at the mid portions on the 90 degree circumference that first, second quadrant on plane, gear place comprised separately, about two interlocking angles symmetrical have in addition a limit with about the side that faces one another of two slide blocks perpendicular and with a tangent horizontal line of described partial gear on, the tip at described two interlocking angles equals partial gear to the distance in the center of circle of described partial gear the center of circle two slide blocks about described face one another the distance of the top, side; And have at the top of the side that left and right sides slide block faces one another one with the corresponding stopper slot in interlocking angle.
Advantage and the good effect that the utlity model has are: because alignment pin on partial gear and tooth all are with same angular speed motion.Both moving radius differences.So the component difference of the linear velocity on the slide block movement direction, the speed of the cylindrical at tooth place are greater than from the center of circle the closely speed of the alignment pin of some.So though alignment pin contacts locating stop piece earlier in partial gear rotates, make the tooth and the tooth bar on the slide block of partial gear can accurately recognize tooth, but because the movement velocity of alignment pin will be lower than the movement velocity of tooth, after tooth and tooth bar engagement, the tooth of partial gear at first promotes slide block action, and alignment pin and locating stop piece are also with regard to fast separation very like this.So alignment pin and locating stop piece have played the guide effect of recognizing tooth, guaranteed the accurate engagement of tooth and tooth bar.In addition because the interlocking angle arranged on partial gear, drive right slide block and upwards close a floodgate when putting in place when partial gear rotates counterclockwise.Left interlocking angle on the partial gear has entered the stopper slot of left slider and has contacted with left slider, like this,, will rotate by driven gear when left slider is upwards promoted as artificial, and gear drives right slide block again downwards the switch separating brake on the right.Vice versa.Thereby realized that being rigidly connected of two slide blocks promptly realized mechanical interlocked.
