Specific embodiment
In order to be easy to understand the technical means, the creative features, the aims and the efficiencies achieved by the present invention, tie below
Conjunction is specifically illustrating, and the present invention is further explained.
As shown in Figure 1-3, a kind of ring network cabinet cabinet door interlock, including the first interlock plate 2, the second interlock plate 4；First
2 upper end of jam plate and breaker division position spinner handle 1 are rotatablely connected, and 2 lower end of the first interlock plate is located at the division position rotation of isolation ground connection
7 top of bar, 4 upper end of the second interlock plate and 2 lower end of the first interlock plate form overlapping region, are located at first in the overlapping region
First sliding groove 3, second sliding slot 5 are respectively set on jam plate 2, the second interlock plate 4, fixing axle 14 passes through first sliding groove 3, second sliding slot
5, the second interlock plate 4, which is located at below the overlapping region, forms groove 13, disconnecting switch division operating shaft 6, earthing switch division
Operating shaft 9 is arranged in parallel with groove 10 respectively, between disconnecting switch division operating shaft 6 and earthing switch division operating shaft 9
Setting isolation ground connection division position spinner handle 7, isolation ground connection division position spinner handle 7 and the second interlock plate 4 rotation connection, preferably every
It is located at 4 upper groove of the second interlock plate, 13 middle position from ground connection division position spinner handle 7 and 4 tie point of the second interlock plate, ground connection is opened
It closes and is socketed cam 8 in division operating shaft 9, doorframe upper end-face edge is located at setting lock pin 11, lock pin 11 below cam 8 and matches with cam 8
It closes, is lockked by the rotation of cam 8 or third interlock plate 10 is set side by side in unlock lock pin 11, doorframe upper end-face edge and lock pin 11.
