The utility model is by arranging push rod, pull bar and slide bar, by being arranged on the opening and closing of the switch member on cabinet door along with cabinet door, band moving slide-bar, pull bar and push rod realize lock operation, guarantee when cabinet door is opened, solid insulation cabinet is in the lock state, and improves its fail safe.
Accompanying drawing explanation
Fig. 1 is the structural representation of solid insulation cabinet.
Fig. 2 is the structural representation omitting cabinet door.
Fig. 3 is that the A-A section of Fig. 2 is attempted.
Fig. 4 is floor map of the present utility model.
Embodiment
Below in conjunction with accompanying drawing, the utility model embodiment is described further:
As Fig. 1, Fig. 2, shown in Fig. 3 and Fig. 4, the utility model provides a kind of cabinet door mechanical interlocking structure for solid insulation cabinet, it comprises cabinet 1, hingedly on described cabinet 1 be provided with cabinet door 2, operating mechanism is provided with in described cabinet, described operating mechanism is provided with position-limited rack 4, pull bar 6 is provided with in described position-limited rack 4, the first resetting device is provided with between described pull bar 6 and position-limited rack 4, described pull bar 6 coordinates along position-limited rack about 4 slippage, described pull bar 6 is provided with push rod 5, described push rod 5 contacts with the sensitive switch 7 on operating mechanism, it has the primary importance of touching sensitive switch 7 and the second place leaving sensitive switch 7, described cabinet door 2 is provided with switch member 8, slide bar 3 is also provided with in position-limited rack 4, described slide bar 3 and pull bar 6 form and are linked, the second resetting device is provided with between described slide bar and cabinet, described switch member 8 is formed with slide bar 3 pushes up press-fit, described cabinet door is opened, the end that switch member 8 unclamps slide bar 3 makes slide bar 3 glide, push rod 5 is driven to leave sensitive switch 7, when described cabinet door 2 is closed, the end of switch member 8 jacking sliding bar 3 makes on slide bar sliding, drives push rod 5 to touch sensitive switch 7.
The two ends, top of described pull bar 6 are protruded and are formed hangers 11, the first resetting device that pull bar 6 is moved downward is provided with between described hangers 11 and position-limited rack 4, described first resetting device is spring, spring one end is set in the other end on hangers 11 and is then fixed on position-limited rack, when separating brake switch is rotated counterclockwise, pull bar glides due to the effect of spring, and the pull bar 6 made departs from the buckle of separating brake switch 14.
Described cabinet 1 inside is provided with and hooks seat 9, and be provided with the second resetting device that slide bar is glided between described hook seat 9 and slide bar 3, described second resetting device is spring.Spring one end is fixed on and hooks on seat, and the other end is fixed on slide bar, and slide bar is provided with multiple fixing hole, for carrying out the fixing point changing spring according to elastic demand, to ensure that spring tension is just drop-down by slide bar, realizes locking.
And when slide bar 3 glides, glide because the pull bar 6 be linked with slide bar 3 also can be driven by it, thus the push rod touching sensitive switch made leaves sensitive switch, achieves blocking function.And when slide bar is up pushed up pressure by switch member, it drives and pull bar to move thus the push rod enable touches sensitive switch again, realize unlocking.
Described top end of sliding rod is provided with bearing, and the cross section of described switch member is trapezoidal.When cabinet door is closed, the bearing on slide bar, along sliding on the inclined-plane of switch member, reduces the frictional force of slide bar and switch member, and switch member structure in echelon, on it, plane is just when cabinet door is closed, and withstands slide bar, prevents it from gliding.
When being provided with fuse in cabinet, described fuse is connected by connecting rod 10 with pull bar 6.Described slide bar 3 is provided with chute 13, and described slide bar 3 contacts with pull bar 6, and described connecting rod 10 is stuck in chute 13 through pull bar 6, makes slide bar 3 and pull bar 6 form slippage and is linked.The operation of separating brake switch 14 can drive fuse work by connecting rod, and when fuse recovers or disconnect, the connecting rod 10 of itself and pull bar 6 secure fit can drivening rod 10 upper and lower slippage chute 13 in, even if after now slide bar is pressed by switch member top, the action of fuse and separating brake switch can not be limited by slide bar, but normally use, and when cabinet door is opened, because connecting rod is positioned at chute topmost, therefore its connecting rod is as the part be linked, pull bar will be driven to glide with slide bar, and realize being linked.
Embodiment should not be considered as restriction of the present utility model, but any improvement done based on spirit of the present utility model, all should within protection range of the present utility model.
