Abstract
The present utility model discloses a breaker locking sheet structure, which belongs to an improved structure of a breaker locking sheet, and aims to provide a breaker locking sheet structure that is easy in processing, convenient and accurate in locking amount control, and reliable in locking and unlocking. The breaker locking sheet structure comprises a locking sheet body showing a question mark shaped structure, wherein the locking sheet body is characterized in that one end surface of the locking sheet body (1) is provided with a locking step (3) with an interior angle being 90 to 110 degree and a height being 0.2 mm. The breaker locking sheet structure, having advantages of simple structure, easily controlled locking amount and reliable locking and unlocking, is an improved structure of the breaker locking sheet.
Description
Technical field
The utility model relates to a kind of lock for circuit breaker stator, relates in particular to a kind of lock for circuit breaker stator and improves structure.
Background technology:Locking plate is a strength member of circuit breaker locking mechanism, and its contour shape directly has influence on the performance of circuit breaker locking mechanism.At present, the profile of lock for circuit breaker stator is generally and roughly is question mark shape structure, and the one of which end is that linear structure, the other end are curvilinear structures.Because the locking plate structure is unreasonable, has the unmanageable defective of dogging beam:, occur locking plate after the armature adhesive easily and be locked the phenomenon that shaft lock is dead, can't thread off if dogging beam is excessive; Otherwise, if dogging beam is too small, then the phenomenon that lock shaft is skidded can appear.At present, the dogging beam of this circuit breaker mainly is to guarantee through the dimensional chain for assembly that control quadric chain and locking mechanism form, and the processing and the assembly precision of part are had relatively high expectations.
Summary of the invention:In order to overcome the defective that exists in the prior art, the utility model aim to provide a kind ofly be convenient to that processing, dogging beam control are convenient accurately, locking and the reliable lock for circuit breaker stator of release structure.
To achieve these goals, the utility model adopts following technical scheme: it comprises the locking plate body that is question mark shape structure, and the end face of locking plate body is provided with the locking step, and the interior angle of this locking step is that 90～110 °, the height of this locking step are 0.2 ㎜.
Compare with prior art, the utility model is owing to adopted technique scheme, and on the basis of traditional locks stator, having increased a height is that 0.2 ㎜, interior angle are 90～110 ° step; Therefore dogging beam is directly guaranteed by the height of step: when semicircular lock shaft clockwise rotated under the effect of armature the suction-combining force, the step on the locking plate just disengaged with lock shaft and realizes release; Otherwise when rotating counterclockwise under the torsion spring elastic force effect that semicircular lock shaft is being mounted thereon, semicircular lock shaft can lock this locking plate through the step on the locking plate.The utlity model has advantages such as simple in structure, that dogging beam is controlled easily, the locking and unlocking is reliable.
Description of drawings:
Fig. 1 is the structural representation of the utility model embodiment.
Among the figure: locking plate body 1 axis hole 2 locking steps 3 lock shaft 4
Embodiment:Below in conjunction with accompanying drawing and concrete embodiment the utility model is described further:
As shown in Figure 1: locking plate body 1 is question mark shape structure, and this locking plate body is provided with axis hole 2, and an end face of locking plate body 1 is provided with the locking step 3 that height H is 0.2 ㎜, the interior angle of this locking step is 90～110 °.
Operation principle: when semicircular lock shaft 4 clockwise rotated under the effect of armature the suction-combining force, the step on the locking plate body 1 just disengaged with lock shaft 4 and realizes release; Otherwise when rotating counterclockwise under the torsion spring elastic force effect that lock shaft 4 is being mounted thereon, this lock shaft can lock this locking plate body through the step on the locking plate body 1.
