Description

Switch cabinet drawer interlocking mechanism

This reality is novel to relate to a kind of switch cabinet drawer interlocking mechanism.

Switch cubicle is very general in complete electricity consumption Application for Field, and the structure of the drawer of traditional switch cubicle is comparatively simple and crude, and does not possess locking mechanism, also can pull out at any time under "on" position, so security performance is not good enough.

The purpose of this utility model is that the drawer that solves existing switch cubicle does not possess locking mechanism, and structure is simple and crude, the problem that security performance is not good enough.The utility model comprises the drawer body, drawer body below is provided with guide pillar, be provided with the actuating axle in the drawer body, detent mechanism, keeper, tooth bar and runner, one end external handle of actuating axle, other end interlock operating mechanism, its middle part is provided with connecting lever, be fixed on and be provided with the helical guide groove that matches with guide pillar in the runner on the drawer body, fixed gear on the runner shaft, gear interlock tooth bar, the keeper and the tooth bar interlock of band groove, detent mechanism is made of base and the stage clip and the motion bar that are assemblied in the base, have breach on the motion bar and cooperate with connecting lever, the bottom of motion bar leans on the sidewall of keeper and matches with groove.

The utility model can only be offed normal switch cabinet drawer at specific branch nest and is put just and can pull out by above-mentioned specific design, has improved the security performance of switch cubicle greatly, has advantage simple and compact for structure, easy to use, the good reliability of assembling.

Below in conjunction with drawings and Examples detailed content of the present utility model is described.

Fig. 1 is a structural representation of the present utility model;

Fig. 2 is the B-B cutaway view of Fig. 1.

As shown in the figure, the utility model comprises drawer body 1, drawer body 1 below is provided with guide pillar 9, be provided with actuating axle 2 in the drawer body 1, detent mechanism, keeper 3, tooth bar 4 and runner 5, one end external handle 6 of actuating axle 2, other end interlock operating mechanism 7, its middle part is provided with connecting lever 13, be fixed on and be provided with the helical guide groove 8 that matches with guide pillar 9 in the runner 5 on the drawer body 1, fixed gear 11 on the runner shaft 10, gear 11 interlock tooth bars 4, the keeper 3 and tooth bar 4 interlocks of band groove 12, tooth bar 4 direction board 18 that links simultaneously, detent mechanism is made of base 14 and the stage clip 15 and the motion bar 16 that are assemblied in the base 14, have breach 17 on the motion bar 16 and cooperate with connecting lever 13, the bottom of motion bar 16 leans on the sidewall of keeper 3 and matches with groove 12.Under the breaker open operation state, motion bar 16 in the detent mechanism is on the plane of keeper 3, and block connecting lever 13 on the actuating axle 2, actuating axle 2 can't rotate combined floodgate, clockwise rotate runner 5, helical guide groove 8 on the runner 5 matches with guide pillar 9 and advances drawer body 1, gear 11 on the runner shaft 10 moves to left with direction board 18 by tooth bar 4 interlock keepers 3 simultaneously and is connected the position, this moment, the bottom of motion bar 16 leaned in the groove 12 on keeper 3 sidewalls, connecting lever 13 is relative with breach 17 on the motion bar 16, rotates actuating axle 2 and closes a floodgate.Otherwise counterclockwise rotating wheel 5 under gate-dividing state, be in the test position this moment, first and second plug-in unit is in coupled situation, move on groove 12 on bottom disengaging keeper 3 sidewalls of motion bar 16, the breach 17 on the motion bar 16, block connecting lever 13 again, circuit breaker can not close a floodgate, drawer body 1 can not be extracted out and advance, continue to rotate counterclockwise runner 5 to separating position, first and second plug-in unit is in released state, and drawer body 1 can be extracted out and advance.
