Abstract
The invention relates to a draw-out circuit breaker, in particular to a device used on the draw-out circuit breaker for displaying the working state of the draw-out position. The invention discloses a novel display unit for the position state of the draw-out circuit breaker, which displays the working state of the circuit breaker by adopting a horizontal mode. When a push plate is pushed, a guide part fixed on the push plate displaces axially along a transmission rod, as the guide part is fixed on the push plate, a torsional guide groove on the transmission rod drives the transmission rod to rotate axially, the axial rotation of the transmission rod further drives a transmission part to perform torsion, and a shift block of the transmission part pushes a slide block to move horizontally through the guide groove, therefore an indicating line at the front end of the slide block moves so as to indicate the working state represented by different characters or symbols. The longitudinal movement of the push plate is converted into the axial rotation of the transmission rod and further converted into the horizontal movement of the slide block, thereby displaying the working state of the circuit breaker with a horizontal display window.
Description
Technical field
The present invention relates to a kind of drawout breaker, a kind of being applied on the pull-out type short-circuiting device shows the device of extracting the residing operating state in position out specifically.
Background technology
For a kind of drawout breaker, the state of circuit breaker three ad-hoc locations in taking out frame: separation, test and link position need to clearly be indicated on panel.At present domestic circuit breaker commonly used all is to buy external product, the perhaps product of foreign imitation, and as shown in Figure 1, its all is circular torsion structure.
Summary of the invention
The purpose of this invention is to provide a kind of novel drawout type circuit breaker position state display device, the mode of employing level shows the operating state of circuit breaker.
The objective of the invention is to be achieved through the following technical solutions:
A kind of display unit for position state of draw-out circuit breaker, be installed in drawout breaker inside, comprise drive link, guide, driving member, slide block, described slide block is positioned at the chute of shell frame inboard, slide block can laterally slide in chute, described drive link passes guide, guide is fixed in the circuit breaker push pedal, guide is provided with guide pad, and corresponding described guide pad is provided with gathering sill at drive link, gathering sill is the torsional mode gathering sill, in the groove of the front end of described driving member insertion drive link, and guarantees not produce relative rotation between driving member and the drive link; The front end of described driving member is provided with shifting block, and corresponding described shifting block is provided with vertical guide groove in the inboard of slide block, and it is inner that described shifting block inserts guide groove; Be provided with at drive link and prevent that the axially movable locating piece of drive link, locating piece are installed on the fixing part in the inner position of circuit breaker.
The groove of selectable drive link front end can be cross, also can limit the structure that drive link and driving member reverse mutually for triangle or square etc.
The front end of described slide block is provided with vertical index line, can show described index line at the window place of shell frame, and below the window or above corresponding ad-hoc location be provided with literal or the symbol of describing working state of circuit breaker.
When promoting push pedal, be fixed on guide in the push pedal on drive link along drive link axial displacement, because guide is fixed in the push pedal, so the torsional mode gathering sill on the drive link can drive drive link and produce axial rotation, the axial rotation of drive link and then drive driving member reverse, the shifting block of driving member promotes slide block by guide groove and does transverse movement, thereby the index line of slip front moves to indicate the operating state of different literal or symbology.
The present invention changes into the axial rotation of drive link with vertically moving of push pedal, and is further converted to the transverse shifting of slide block, thereby demonstrates the operating state of circuit breaker with the display window of level.

Embodiment
Shown in Fig. 2-7, and in conjunction with Fig. 8-Figure 13, display unit for position state of draw-out circuit breaker of the present invention, be installed in drawout breaker inside, comprise drive link 40, guide 30, driving member 50, slide block 60, described slide block 60 is positioned at the chute 71 of shell frame 70 inboards, slide block 60 can be in chute 71 interior horizontal slips, described drive link 40 passes guide 30, guide 30 is fixed in the circuit breaker push pedal 20, guide 30 is provided with guide pad 31, and corresponding described guide pad 31 is provided with gathering sill 41 at drive link 40, gathering sill 41 is torsional mode gathering sill 41, in the groove 42 of the front end of described driving member 50 insertion drive links 40, and guarantees not produce relative rotation between driving member 50 and the drive link 40; The front end of described driving member 50 is provided with shifting block 51, and corresponding described shifting block 51 is provided with vertical guide groove 61 in the inboard of slide block 60, and described shifting block 51 inserts guide groove 61 inside; Be provided with at drive link 40 and prevent that drive link 40 axially movable locating pieces 43, locating piece are installed on the fixing part 10 in the inner position of circuit breaker.
The groove 42 of selectable drive link 40 front ends can be cross, also can limit the structure that drive link 40 and driving member 50 reverse mutually for triangle or square etc.
The front end of described slide block 60 is provided with vertical index line 62, can show described index line 62 at window 72 places of shell frame 70, and below the window 72 or above corresponding ad-hoc location be provided with literal or the symbol 73 of describing working state of circuit breaker.
When promoting push pedal 20, be fixed on guide 30 in the push pedal 20 on drive link 40 along drive link 40 axial displacements, because guide 30 is fixed in the push pedal 20, so the torsional mode gathering sill 41 on the drive link 40 can drive drive link 40 and produce axial rotation, the axial rotation of drive link 40 and then drive driving member 50 reverse, the shifting block 51 of driving member 50 promotes slide block 60 by guide groove 61 and does transverse movement, thereby the index line of slide block 60 front ends moves to indicate the operating state of different literal or symbology.
