Utility model content
The purpose of this utility model is: for the above-mentioned technical problem existed in prior art, provides a kind of side to grasp jack box linked protection mechanism.
The utility model is achieved through the following technical solutions:
Side behaviour's jack box linked protection mechanism, comprise jack box and linked protection mechanism, described jack box is by casing, door-plate, upper sealing plate and lower shrouding composition, described linked protection mechanism is by chain fixing hook tabs, chain cross bar, switch handle, switch plectrum and Door lock with linakage locking bar catch composition, described chain cross bar is U-shaped, a U-shaped end of chain cross bar is arranged on box inside, the other end is provided with chain fixing hook tabs, the side of described casing has the through hole supplying the hook portion of chain fixing hook tabs to pass, between the both ends of chain cross bar, switch handle and switch plectrum are also installed, described switch handle is arranged on outside door-plate through door-plate, and the door-plate inner face relative with switch handle is provided with Door lock with linakage locking bar catch.
As preferably, described lower shrouding has square hole, square hole is provided with the little shrouding that shape size matches.
As preferably, described switch handle is fixedly connected with chain cross bar through switch handle, pad one, pad two, pad one successively by bolt one and bolt two.
As preferably, the thickness of described pad two is slightly larger than pad one.
In sum, owing to have employed technique scheme, the beneficial effects of the utility model are:
Compared with prior art, the utility model adds linked protection mechanism on jack box, circuit breaker in jack box is closed a floodgate energising under the stirring of switch plectrum, the Door lock with linakage locking bar catch of linked protection mechanism pins chamber door simultaneously, chain fixing hook tabs catches on bus groove case, when ensure that the energising of jack box combined floodgate, jack box chamber door and plug jack box cannot be opened, jack box is run safer.
