In the present embodiment, when described sliding panel 2 is positioned at initial position, when the described through hole on described sliding panel 2 overlaps with the described rocking handle jack on described Shell of circuit breaker, can normally insert use rocking handle, circuit breaker can normally use; When described sliding panel 2 slides into latched position, described sliding panel 2 covers on described rocking handle jack, and latched position can be locked in by described locked component, namely described sliding panel 2 will block the side of described rocking handle jack, rocking handle cannot be stretched in described circuit breaker by described rocking handle jack, thus the locking to described rocking handle jack can be realized, prevent described rocking handle in unwanted situation, be mistakenly inserted in described circuit breaker, cause the misoperation of circuit breaker or bring potential safety hazard; This kind of latch-up structure is applicable to the circuit breaker using rocking handle, and structure is simple, is easy to operation.
Also be provided with bias piece between described sliding panel 2 and described circuit breaker case 1, described bias piece is applied with all the time described sliding panel and makes described sliding panel 2 have the biasing force of the movement tendency being slided to described latched position by described initial position.Namely, in the present embodiment, after rocking handle is extracted out, described sliding panel 2 can automatically have initial position to slide to latched position under the effect of described bias piece, thus initiatively covers the described rocking handle jack on described circuit breaker case 1; If now do not lock described sliding panel 2, the skewed slot will propped up on described sliding panel 2 after described rocking handle inserts described rocking handle jack, and then the component along its glide direction is applied to described sliding panel 2, the biasing force that this component makes described sliding panel 2 overcome described bias piece slides into described initial position by described latched position, and then described rocking handle can stretch into described circuit breaker internal through described through hole, and then cause the misoperation of circuit breaker; If locked the described sliding panel 2 being positioned at described latched position by described locked component, then described lockplate 2 is locked, and rocking handle cannot stretch into described circuit breaker internal.
Particularly, as illustrated in fig. 1 and 2, described sliding panel 2 forms L-type cavity 3, described L-type cavity 3 comprises the first sliding tray 31 of the glide direction being parallel to described sliding panel 2 and the second sliding tray 32 perpendicular to described sliding panel 2 direction;
Described locked component comprises the limiting plate 4 be slidably arranged on through described L-type cavity 3 in described circuit breaker case 1; Specifically as shown in Figure 2, described limiting plate 4 forms limiting section 41 and concave part 42; And line-locked locking piece can be entered to described limiting plate 4;
As best shown in figures 5 and 7, when described sliding panel 2 slides into latched position, limiting plate 4 described in push-and-pull makes described limiting section 41 coordinate with described second sliding tray 32, and makes described locking piece lock described limiting plate 4, then described sliding panel 2 is locked in latched position; Be separated described locking piece and described limiting plate 4, limiting plate 4 described in push-and-pull makes described concave part 42 coordinate with described L-type cavity 3, and described sliding panel 2 latch-release, described sliding panel 2 can slide between described initial position and described latched position, as shown in Figure 8.
Described first sliding tray 31 equals the sliding stroke of described sliding panel 2 along the size of described sliding panel 2 length direction.
In the present embodiment, be also provided with the guide frame that can lead to the slip of described sliding panel 2; Arranging of described guide frame can be led to the slip of described sliding panel 2, ensures the smooth slip of described sliding panel 2 between described initial position and described latched position.
Wherein, described guide frame comprises described guide protrusions 51/ direction recess 52 through end 43 side being molded over described limiting plate 4, and is molded over direction recess 52/ guide protrusions 51 that can match with described guide protrusions 51/ direction recess 52 on described sliding panel 2.
Specifically as shown in Figure 7, described direction recess 52 is molded over the described through on end 43 of described limiting plate 4, described guide protrusions 51 is molded over described sliding panel 2 towards on the described sidewall through end 43 side, and described guide protrusions 51 extends along the glide direction of described sliding panel 2.
As shown in Figure 6, described limiting plate 4 forms locked groove 44 through the end 43 that passes of described L-type cavity 3; Described locking piece is set to is located at the described sliding pin 6 through end 43 side slidably; When the described concave part 42 of described limiting plate 4 coordinates with described L-type cavity 3, described sliding pin 6 can slip into described locked groove 44 and lock described limiting plate 4.
As shown in Figures 3 and 4, described sliding pin 6 is slidably mounted on described circuit breaker case 1 by connector 7, and described connector 7 to be fixedly mounted on described circuit breaker case 1 and to have a chute slided for described sliding pin 6; Wherein, described chute is provided with two spacing stops 71, and described sliding pin 6 has lug boss 61 protruding upward, and described lug boss 61, between two described spacing stops 71, deviates from described chute to prevent described sliding pin 6.
In order to prevent described limiting plate 4 because push-and-pull transition is from described L-type cavity 3, ensure that the push-and-pull of described limiting plate 4 is positioned at certain limit all the time, to carry out spacing to described sliding panel 2 or to remove spacing smoothly, described limiting plate 4 also forms the barrier structure preventing described limiting plate 4 from deviating from described L-type cavity 3.
The specific works process of the latch-up structure described in the present embodiment is as follows:
When circuit breaker does not insert rocking handle, in order to prevent being mistakenly inserted of rocking handle, need to carry out temporary locking to the described rocking handle jack on described circuit breaker case 1; Now, first make described sliding panel 2 slide into described latched position by initial position, make described sliding panel 2 cover the top of described rocking handle jack; Then limiting plate 4 described in push-and-pull makes the described stop part on described limiting plate 4 coordinate with the second vertical sliding tray 32 of described L-type cavity 3, and described sliding panel 2, under the restriction of described stop part, no longer slides; Finally, the described sliding pin 6 that slides makes it coordinate with the described described locked groove 44 through end 43 of described limiting plate 4, thus is locked by described limiting plate 4, and then is locked by described sliding panel 2; By said process, complete the locking process of described rocking handle jack on described circuit breaker case 1, rocking handle cannot be inserted in circuit breaker by described rocking handle jack.
When needs unlock, be first separated described sliding pin 6 and described limiting plate 4, then limiting plate 4 described in push-and-pull, the described concave part 42 on it coordinated with described L-type cavity 3, the locking to described sliding panel 2 can be removed; Now, described sliding panel 2 can slide arbitrarily between described initial position and described latched position.
Obviously, above-described embodiment is only for clearly example being described, and the restriction not to execution mode.For those of ordinary skill in the field, can also make other changes in different forms on the basis of the above description.Here exhaustive without the need to also giving all execution modes.And thus the apparent change of extending out or variation be still among the protection range of the invention.
