The utility model content
Technical problem to be solved in the utility model provides a kind of multi-loop combined switch lever type mechanical interlocking device, and it has adopted the lever operation principle and has been suitable for installing and using in the multi-loop combined switch equipment.
For solveing the technical problem, the utility model provides a kind of multi-loop combined switch lever type mechanical interlocking device, it is characterized in that, it comprises the isolating switch main shaft, isolating switch, the interlocking slide block, the first lever rotating type mechanism, connecting rod, the second lever rotating type mechanism, interlocking segment, the first main chamber Da Gai, the second main chamber Da Gai, the 3rd main chamber Da Gai, door-opening mechanism, the isolating switch main shaft is fixed on the isolating switch and passes the interlocking slide block, interlocking slide block and connecting rod are slidingly connected, the second lever rotating type mechanism and interlocking segment are slidingly connected, the first lever rotating type mechanism and connecting rod are slidingly connected, the first main chamber Da Gai, the second main chamber Da Gai, the big lid sequence arrangement in the 3rd main chamber, the first main chamber Da Gai, big lid in the 3rd main chamber and interlocking segment are fixed, the door-opening mechanism and the first main chamber Da Gai, the second main chamber Da Gai, the big lid in the 3rd main chamber connects.
Preferably, the two ends, the left and right sides that are shaped as of described isolating switch main shaft are curve, and two ends are straight line up and down.
Positive progressive effect of the present utility model is: multi-loop combined switch can not be opened main chamber Da Gai when the work operation; Open main chamber Da Gai, must cut off the electricity supply earlier; Power connection just can carry out behind the big lid in main chamber that must close earlier, has guaranteed the safe operation and the maintenance of multi-loop combined switch.

Embodiment
Lift a preferred embodiment below, and come the clearer the utility model that intactly illustrates in conjunction with the accompanying drawings.
As shown in Figure 2, the utility model multi-loop combined switch lever type mechanical interlocking device comprises isolating switch main shaft 1, isolating switch 2, interlocking slide block 3, the first lever rotating type mechanism 4, connecting rod 5, the second lever rotating type mechanism 6, interlocking segment 7, the big lid 8 in the first main chamber, the big lid 9 in the second main chamber, the big lid 10 in the 3rd main chamber, door-opening mechanism 21, isolating switch main shaft 1 is fixed on the isolating switch 2 and passes interlocking slide block 3, interlocking slide block 3 is slidingly connected with connecting rod 5, the second lever rotating type mechanism 6 and interlocking segment 7 are slidingly connected, the first lever rotating type mechanism 4 is slidingly connected with connecting rod 5, the big lid 8 in the first main chamber, the big lid 9 in the second main chamber, big lid 10 sequence arrangement in the 3rd main chamber, the big lid 8 in the first main chamber, big lid 10 in the 3rd main chamber and interlocking segment 7 are fixing, the big lid 8 of the door-opening mechanism 21 and the first main chamber, the big lid 9 in the second main chamber, the big lid 10 in the 3rd main chamber connects.The two ends, the left and right sides that are shaped as of isolating switch main shaft 1 are curve, and two ends are straight line up and down.
The first lever rotating type mechanism 4 is closing and divide of interlocking isolating switch, and interlocking slide block 3, connecting rod 5 are all formed together with the first lever rotating type mechanism 4, and interlocking slide block 3 can isolated pass 2 be connected and pin can not move left and right.The second lever rotating type mechanism 6 is Push And Releases of the big lid in the main chamber of interlocking, and the big lid 10 in big lid the 9, the 3rd main chamber, big lid 8, the second main chamber, the first main chamber is because of being pinned by the second lever rotating type mechanism 6, and such second lever rotating type mechanism 6 also is lockable.Three main chamber Da Gai can not open because of pinning, and this can not uncap and safe operation under energising operation working condition with regard to having guaranteed multi-loop combined switch.
When multi-loop combined switch need be uncapped maintenance, at first must be with the isolating switch disjunction, isolating switch main shaft 1 is in position shown in Figure 3, just release of isolating switch at this moment.Turn clockwise 4 to 90 ° in the first lever rotating type mechanism, interlocking slide block 3 that interconnects and connecting rod 5 40mm that just can move right, this moment, the second lever rotating type mechanism 6 all was unlocked.As long as 6 to 90 ° in the up time second lever rotating type mechanism just can be moved to the left 40mm by rotating the big lid 8 in door-opening mechanism 21, the first main chambeies again, the big lid 10 in big lid the 9, the 3rd main chamber, the second main chamber just can move right 40mm and open.
After three main chamber Da Gai open, as shown in Figure 4,, just can not turn to closing position again, guarantee to switch on after isolating switch is uncapped because of isolating switch is lockable.Want the work of switching on again, unique method is exactly that all main chamber big lid Men Douyi shut and put in place, again by being rotated counterclockwise the second lever rotating type mechanism 6 to the zero-bit position, like this all big cover locks in main chamber is lived again.Untie the interlocking slide block 3 that interconnects and the interlocking of connecting rod 5, just can be rotated counterclockwise the first lever rotating type mechanism 4 to the zero-bit position, drivening rod 5, interlocking slide block 3 is moved to the left 40mm, and this moment, the isolating switch main shaft just can rotate to the position of closing.
Though more than described embodiment of the present utility model, but those skilled in the art is to be understood that, these only illustrate, and under the prerequisite that does not deviate from principle of the present utility model and essence, can make numerous variations or modification to these execution modes.Therefore, protection range of the present utility model is limited by appended claims.
