Specific embodiment
Present invention is described in detail with reference to Figure of description and embodiment：
A kind of implementation of primary cut-out machinery closing locking device for being provided for the present invention as shown in Figures 1 to 4 is illustrated
It is intended to, it is included on main shaft 4 and with the closing locking baffle plate 1 of the rotation of main shaft 4, on propulsive mechanism square bar 5 and with side
The interlocking bent plate 2 that bar 5 is rotated and the transmission component 3 between closing locking baffle plate 1 and interlocking bent plate 2.
The middle part of the transmission component 3 is hinged on casing, the jointed shaft (i.e. support bar 32) of transmission component 3, main shaft 4 and
Square bar 5 is spatially mutually perpendicular to two-by-two, and the one end of transmission component 3 is driven by bent plate 2 of interlocking and rotated, and the other end is closed with combined floodgate
The spacing cooperation of stopper plate 1.
The main shaft 4 is for controlling primary cut-out on/off switch.
When primary cut-out is in closing position, main shaft 4 drives closing locking baffle plate 1 to turn to limitation transmission component 3
Turned position so that transmission component 3 and the interlocking bent plate 2 being linked therewith and square bar 5 cannot be rotated, afterwards handle behaviour
Making baffle plate 7 cannot push, and operation handle cannot insert drive drive screw rotation in spacing hole and carry out pressure separating brake.
When primary cut-out is in open position, main shaft 4 drives closing locking baffle plate 1 to turn to unrestricted transmission component
3 turned positions, transmission component 3 and the interlocking bent plate 2 being linked therewith and square bar 5 are rotatable, and handle operation baffle plate 7 can
Normally push, by operation handle drive screw can be driven to rotate.
The transmission component 3 includes the support bar 32 being installed on casing and the driver plate for being hinged on the upper end of support bar 32
31。
Driver plate 31 is provided with two block pieces near interlocking bent plate 2 one end, respectively positioned at the block piece of interlocking bent plate 2 side clockwise
The A33 and block piece B34 positioned at interlocking bent plate 2 side counterclockwise, interlocking bent plate 2 be located between two block pieces and with block piece A33 and gear
Part B34 is spaced a distance.
The block piece A33 includes vertically extending part and the lateral extension portions A located at vertically extending part upper end；Institute
Stating block piece B34 includes lateral extension portions B.
Handle operation baffle plate 7 is pushed, square bar 5 drives interlocking bent plate 2 to rotate clockwise, and block piece A33 is by the band of interlocking bent plate 2
It is dynamic, whole driver plate 31 is rotated clockwise (supreme to look down)；When handle operation baffle plate 7 resets, interlocking bent plate 2 drives B34,
Rotate counterclockwise whole driver plate 31.
The vertically extending part of block piece A33 is disposed to the rotation for making lateral extension portions A be more nearly interlocking bent plate 2
Axle, and then reduce the anglec of rotation of driver plate 31.
Driver plate 31 is provided with pushing plate 35 near the one end of closing locking baffle plate 1, and the pushing plate 35 faces closing locking gear
The direction of plate 1.
The operation principle of primary cut-out machinery closing locking device：
1. when primary cut-out is in gate-dividing state, baffle plate 7 is operated by lower handle, operation handle is inserted, handle operation
Baffle plate 7 drives interlocking bent plate 2 to turn clockwise, and interlocking bent plate 2 drives driver plate 31 to turn clockwise, the now conjunction on main shaft 4
Lock latch-down baffle 1 is in open position, it is impossible to hinder driver plate 31 to rotate, and breaker can be carried out to shake into grade work is shaken out, joins
See Fig. 2.
2. when operation handle is extracted from drive screw 6, handle operation baffle plate 7 automatically resets, and drives interlocking bent plate 2 inverse
Hour hands rotate, and interlocking bent plate 2 drives the rotate counterclockwise of driver plate 31, are automatically performed primary cut-out machinery closing locking device
Reset work.
3. when primary cut-out is in "on" position, main shaft 4 drives closing locking baffle plate 1 to rotate counterclockwise to limitation transmission
The turned position of plate 31.Now, closing locking baffle plate 1 plays interlocking and stops to driver plate 31, interlocking bent plate 2, handle operation baffle plate 7
Effect, operation handle in cannot inserting drive screw 6 shake into shaking out, referring to Fig. 1.
