Embodiment
Now in conjunction with the accompanying drawings embodiments of the present invention are further described:
As shown in the figure, the embodiment of three position local devices of a kind of withdrawable circuit breaker of the present invention, comprise two bearings 1 that are located on the base plate 3,2, be located on the base plate 3 and be positioned at bearing 1, the slide plate 11 in 2 the place aheads, be located on the preceding bearing 2 and the drive lead screw 6 that is connected with slide plate 11, on preceding bearing 2, be fixed with first square shaft 8, the front end of this first square shaft 8 passes the riser 101 of slide plate 10, on first square shaft 8, be provided with three grooves 81, at the rear side of riser 101 clamp 9 parallel that be sticked with riser 101, also be provided with a limiting plate 111 that prevents clamp 9 and riser 101 relative separation at the rear side of clamp 9, the thickness of this clamp 9 is slightly smaller than the width of the first square shaft groove 81, between clamp 9 and riser 101, be provided with a spring 7, these spring 7 one ends are fixed on the clamp 9, the other end is fixed on the riser 101, clamp 9 constitutes the lateral deviation that makes progress by this spring 7 and puts, preceding bearing 2 is provided with a latch release shaft 5 (this latch release shaft 5 surpasses rear support 1 simultaneously and is connected with a knob), in latch release shaft 5 epirelief length corresponding three jacking blocks 51 in three groove 81 positions with first square shaft 8 are arranged, on latch release shaft 5, also be arranged with a torsion spring 12, one end of this torsion spring 12 is stuck on the rear support 1 of base plate 3, the other end is stuck on the latch release shaft 5, latch release shaft 5 by this torsion spring 12 to order about it along circumferentially counterclockwise deflection, on riser 101, be provided with first party axis hole 1012, screw hole 1013 and release axis hole 1011, this first party axis hole 1012 passes for first square shaft 8, this screw hole 1013 cooperates with screw mandrel 6 spirals, this release axis hole 1011 passes through for latch release shaft 5, thereby and the edge of the release axis hole 1011 of this riser 101 greater than jacking block 51 outer tracks of latch release shaft 5 deflections when push rod 51 just is positioned at this release axis hole 1011, the counterclockwise deflection of meeting is (in the diagram under the effect of torsion spring 12, the release axis hole 1011 of this riser 101 is the shape of quadrant), also be provided with first party axis hole 92 on the described clamp 9, screw hole 93 and release axis hole 91, this first party axis hole 92 passes through for first square shaft 8 too, this screw hole 93 is the square hole of open lower side, also be provided with a boss 911 in the release axis hole 91 of this clamp 9, in torsion spring 12 effect deflect, described clamp 9 has the primary importance the groove 81 of holding at first square shaft 8 under spring 7 active forces in and moves the second place that makes its boss 911 and jacking block 51 clamping matching at the jacking block 51 overhead power bottom offsets of latch release shaft 5 push rod 51 clamping matching of described boss 911 and latch release shaft 5 with restriction latch release shaft 5.Present embodiment in use, make drive lead screw 6 rotations when shaking handle, drive lead screw 6 drives slide plate 10 and clamp 9 displacements, when clamp 9 is moved to groove 81 positions of first square shaft 8, clamp 9 is under the pulling force of spring 7 and card drops in the groove 81, because clamp 9 and riser 101 can relative separation, and therefore also promptly stuck relatively riser 101, so also just again rotary screw rod 6 make slide plate 10 displacements, so just play locking action; And when desiring release, only need clockwise rotate latch release shaft 5, the jacking block 51 of latch release shaft 5 upwards makes clamp 9 break away from the groove 81 of first square shaft 8 in the top clamp 9, when separating the latch release shaft 5 that comes loose when bearing pin 5 is rotated in place, because this moment, the release axis hole 91 interior boss 911 of clamp 9 can block jacking block 51, therefore latch release shaft 5 can't turning anticlockwise, described jacking block 51 still withstands clamp 9, at this moment just can shake handle moves slide plate 10, at this moment just be in the unlocked position, when moving a certain distance a little, slippage make jacking block 51 break away from and enter the release axis hole 1011 of riser 101 from the release axis hole 91 of clamp 9, at this moment the release axis hole 91 interior boss 911 that also are jacking block 51 and clamp 9 are thrown off, because the edge of the release axis hole 1011 of this riser 101 is greater than jacking block 51 outer tracks of latch release shaft 5 deflections, therefore latch release shaft 5 spinning reduction counterclockwise under the effect of torsion spring 12, thus prepare for release next time.
In the present embodiment, stationarity during in order to ensure locking, also be provided with second square shaft 4 identical on the described rear support 2 with first square shaft 8, this first, second square shaft 8,4 is divided into the outside of screw mandrel 6 and latch release shaft 5, lock clamp 9 simultaneously by establishing two square shafts 4,8, make clamp 9 lockings more firm like this.But obvious, even adopt the mode of a square shaft also still to belong to protection scope of the present invention.
In the illustrated embodiment, for can being blocked in the groove that drops on square shaft when the displacement swimmingly, clamp 9 locks, described first, second square shaft 4,8 groove 41,81 oral area both sides are provided with down hypotenuse 411 (as shown in Figure 2), utilize hypotenuse 411 can guide clamp 9 successfully to snap in square shaft 4 like this, 8 groove 41, in 81, thereby also can be with groove 41,81 width is done little as far as possible, to guarantee the accuracy of screens, and say as the front, if it also is feasible certainly that the ditch notch is not established down hypotenuse, clamp is smooth and easy to be entrapped in the square shaft groove but in order to make, may need groove width is strengthened, but such accuracy that also will influence screens.
As shown in the figure, the jacking block 51 of described latch release shaft 5 be rounded down 511 in the opposite side of torsion spring 12 active force deflect directions, be provided with rounding 511 beyond doubt in order when carrying out the release action, to rotate latch release shaft 5 more effortlessly, and, also can influence operating handle in addition if easy to wear first with wedge angle.
In the present embodiment as described in Figure, described clamp 9 is connected with riser 101 by pilot pin 11, described pilot pin 11 be T shape pin, the head of this T shape pin constitutes described limiting plate 111, the number of pilot pin 11 is two diagonal angles that two (obviously also can be other numbers) are divided into clamp 9.Connecting by pilot pin 11 also is the most common connected mode; Yet the present invention certainly do not get rid of yet adopt any other make can not separate between clamp and riser relative and can about the mode of planar slip, be provided with the independently mode of baffle plate as rear side at clamp, the connected mode that all is not so good as T shape pilot pin when these modes is come conveniently, and the connected mode that therefore adopts T shape pilot pin is when being preferred mode.
Although the applicant has done comparatively detailed explanation and description to embodiments of the invention in conjunction with the accompanying drawings; but it should be appreciated by those skilled in the art; above embodiment only is an optimal way of the present invention; be in order to understand the present invention better; and be not restriction to protection scope of the present invention, any improvement of being done based on invention spirit of the present invention is all naturally within protection scope of the present invention.
