Abstract
The utility model provides an explosion -proof operating device of miniature circuit breaker, includes flame proof lid, the flame proof body, miniature circuit breaker, pivot, transition pivot, operating handle and shift fork, flame proof lid lock is on the flame proof body and pass through the screw connection, and the flame proof lid limits out an accommodation space with the flame proof body jointly, is equipped with miniature circuit breaker in this accommodation space, the articulated pivot that has is covered to the flame proof, and outer end and the inner of pivot are connected with operating handle and transition pivot respectively, the pivot of should passing through connection shift fork, handle cooperation on shift fork and the miniature circuit breaker. Since adopt foretell structural design, during the use, through the rotation of operating handle drive pivot, the rotation of rethread transition pivot and then drive shift fork, miniature circuit breaker's handle can be stirred in the rotation of shift fork to realize opening and shutting of miniature circuit breaker, long service life not only, the reliability is high moreover, can realize that miniature circuit breaker is seamless to assemble the combination, but also exclusive use.
Description
Technical field
This utility model relates to miniature circuit breaker technical field, especially one miniature circuit breaker explosive operation mechanism.
Background technology
Miniature circuit breaker refers to close, carry and cut-off the electric current under normal loop condition the switching device of electric current that can close, carry within the time of regulation and cut-off under abnormal loop condition.If miniature circuit breaker is used in the place with requirement of explosion proof, chopper must be put into flame-proof type housing, not allow operation of uncapping, can only carry out operating outside panel by having the operating mechanism of explosion prevention function, realize the breaking function of miniature circuit breaker, reach explosion-proof requirement.
Current miniature circuit breaker explosive operation mechanism, when composite assembly, wastes time and energy and is not easy alignment, be not easy to install during installation, need to adjust screw many times, and easily thread off.Existing miniature circuit breaker is usually present that service life is shorter, reliability is poor, can not split arbitrarily assemble, and brings much inconvenience to workman when installing, it is impossible to enough improve the problems such as production efficiency.
Therefore, prior art needs to be improved and improves.
Summary of the invention
In view of this, to be to provide length in a kind of service life, reliability high for the purpose of this utility model, it is possible to realize the combination in any of miniature circuit breaker by lengthening upper backup pad.
For achieving the above object, this utility model be the technical scheme is that
A kind of miniature circuit breaker explosive operation mechanism, including flame proof lid, flame proof body, miniature circuit breaker, rotating shaft, transition rotating shaft, operation handle and shift fork, described flame proof cover buckle is combined on flame proof body and is connected by screw, flame proof lid and flame proof body define an accommodation space jointly, are provided with miniature circuit breaker in this accommodation space；Being hinged with rotating shaft on described flame proof lid, the outer end of rotating shaft and the inner are connected to operate handle and transition rotating shaft, and this transition rotating shaft connects shift fork, and described shift fork coordinates with the handle on miniature circuit breaker.
Further, it is provided with sealing strip between described flame proof lid and flame proof body.
Further, the base plate of described flame proof body being fixedly connected with installation guide rail by screw, this installation guide rail hangs down is provided with left support plate and right support plate, for the miniature circuit breaker being arranged on guide rail between this left and right gripper shoe；Described left support plate is connected with the top of right support plate upper backup pad, and this upper backup pad has placed rotating transition rotating shaft.Any assembling combination that miniature circuit breaker such as 1P, 2P, 3P, 4P, 1P+N, 2P leak electricity, 3P leaks electricity, 4P leaks electricity can be realized by lengthening upper backup pad.
Compared with prior art, the beneficial effects of the utility model are: owing to using above-mentioned structure design, during use, moved the rotation of rotating shaft by manipulator's grip strip, then by transition rotating shaft and then the rotation of drive shift fork, the rotation of shift fork can stir the handle of miniature circuit breaker, thus realize the folding of miniature circuit breaker, not only service life is long, and reliability is high, the assembling combination that miniature circuit breaker is seamless can be realized, it is possible to be used alone.
