Limiting mechanism is equipped at the sliding slot.

The two sides up and down of any one sliding slot are equipped with limit press strip, have between two limit press strips and mutually fit with linkage pillar The slot matched limits the space that fixed multipole interlocking bar is formed between press strip and partition, and one end of the multipole interlocking bar plugs In the space, and cooperation can be slid along the chute, the length of the limit press strip is greater than the skidding distance of multipole interlocking bar.

The length of limit press strip on the downside of sliding slot is greater than the length for the limit press strip being located on the upside of sliding slot.

Supporting bable tops are formed between the limit press strip and partition positioned at downside.

The side of the supporting bable tops and the cooperation of multipole interlocking bar is equipped with arc surface.

Two sliding slots are arranged in parallel, and one of sliding slot is arranged higher than another sliding slot.

Higher sliding slot is equipped with gap close to the side of lower sliding slot.

The limiting mechanism setting is at linkage pillar.

Any one linkage pillar two sides extends outward to form limited block, and the limited block and partition sliding are arranged.

The utility model has the beneficial effects that sliding slot and multipole interlocking bar are carried out position restriction using limiting mechanism, moreover it is possible to Guarantee multipole interlocking bar slid in the space being made of limiting mechanism, using single part realize multipole interlocking bar positioning and Assembly simplifies inner space, reduces cost.

Specific embodiment

The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model Clearly and completely describing, it is clear that described embodiment is only a part of the embodiment of the utility model, rather than all Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are not making creative work premise Under every other embodiment obtained, fall within the protection scope of the utility model.

It is to be appreciated that the directional instruction (such as up, down, left, right, before and after ...) of institute in the utility model embodiment It is only used for explaining in relative positional relationship, the motion conditions etc. under a certain particular pose (as shown in the picture) between each component, such as When the fruit particular pose changes, then directionality instruction also correspondingly changes correspondingly.

In the present invention unless specifically defined or limited otherwise, term " connection ", " fixation " etc. should do broad sense reason Solution, for example, " fixation " may be a fixed connection, may be a detachable connection, or integral；It can be mechanical connection, it can also To be electrical connection；It can be directly connected, the connection inside two elements can also be can be indirectly connected through an intermediary Or the interaction relationship of two elements, unless otherwise restricted clearly.It for the ordinary skill in the art, can be with The concrete meaning of above-mentioned term in the present invention is understood as the case may be.

In addition, the description for being such as related to " first ", " second " in the present invention is used for description purposes only, and cannot manage Solution is its relative importance of indication or suggestion or the quantity for implicitly indicating indicated technical characteristic.Define as a result, " the One ", the feature of " second " can explicitly or implicitly include at least one of the features.In addition, the skill between each embodiment Art scheme can be combined with each other, but must be based on can be realized by those of ordinary skill in the art, when technical solution It will be understood that the combination of this technical solution is not present in conjunction with there is conflicting or cannot achieve when, also not in the utility model It is required that protection scope within.

The utility model provides a kind of multipole linkage structure of integral type leakage circuit breakers in single-chamber comprising has The shell 1 and multipole interlocking bar 2 of left and right chamber are equipped with partition between the chamber of left and right, and the both ends of multipole interlocking bar 2 are equipped with connection Pillar 21 is moved, the position that the linkage pillar of multipole interlocking bar is corresponded on the partition is equipped with sliding slot 12, and two sliding slots are arranged in parallel, And one of sliding slot is arranged higher than another sliding slot.

The two sides up and down of one of sliding slot 12 are equipped with limit press strip 11, have between two limit press strips 11 convex with linkage The compatible slot of column 21, linkage pillar 21 are embedded in the slot, and can slide along the slot, limit press strip 11 and partition it Between form the space of fixed multipole interlocking bar 2, one end of the multipole interlocking bar is plugged in the space, is limited press strip limit System can slide cooperation in the space along the chute, and the length of the limit press strip 11 is greater than the skidding distance of multipole interlocking bar, In the sliding of multipole interlocking bar, it can be limited press strip limitation always, can't fall off, and the length of the limit press strip is slightly longer It in multipole interlocking bar skidding distance, only prevents it from falling off in movement, and will not influence the assembly of multipole interlocking bar in assembly.

Limit the distance between the press strip and partition are equal to or more than the thickness of multipole interlocking bar, for limiting multipole connection Lever, multipole interlocking bar can slide in the space, and can be limited by the limit press strip.
