Label declaration: 1 closing locking baffle plate, 2 interlocking bent plates, 3 transmission components, 31 driver plates, 32 support bars, 33 block piece A, 34 block piece B, 35 slurcams, 4 main shafts, 5 square bars, 6 drive screw mandrel, 7 lever operated baffle plates.
Embodiment
Below in conjunction with Figure of description and embodiment, content of the present invention is described in detail:
Be the embodiment schematic diagram of a kind of primary cut-out provided by the invention machinery closing locking device as shown in Figures 1 to 4, it comprises is located on main shaft 4 and the closing locking baffle plate 1 rotated with main shaft 4, is located on propulsive mechanism square bar 5 and the interlocking bent plate 2 rotated with square bar 5 and the transmission component 3 between closing locking baffle plate 1 and interlocking bent plate 2.
Be hinged on casing in the middle part of described transmission component 3, the jointed shaft (i.e. support bar 32) of transmission component 3, main shaft 4 and square bar 5 are spatially mutually vertical between two, and transmission component 3 one end drives rotation by interlocking bent plate 2, the other end coordinates with closing locking baffle plate 1 is spacing.
Described main shaft 4 is used to control 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 restriction transmission component 3 turned position, transmission component 3 and the interlocking bent plate 2 be linked with it and square bar 5 all cannot be rotated, afterwards lever operated baffle plate 7 cannot press down, and operating grip cannot insert in spacing hole to drive and drive screw mandrel rotation to 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 position, transmission component 3 and the interlocking bent plate 2 be linked with it and square bar 5 all rotatable, lever operated baffle plate 7 can normally press down, and drives drive screw mandrel to rotate by operating grip.
Described transmission component 3 comprises the support bar 32 be installed on casing and the driver plate 31 being hinged on support bar 32 upper end.
Driver plate 31 is provided with two block pieces near interlocking bent plate 2 one end, be respectively be positioned at interlocking bent plate 2 clockwise side block piece A33 and be positioned at the block piece B34 of interlocking bent plate 2 side counterclockwise, interlocking bent plate 2 is between two block pieces and be all spaced a distance with block piece A33 and block piece B34.
Described block piece A33 comprises vertical extension and is located at the lateral extension portions A of upper end, vertical extension; Described block piece B34 comprises lateral extension portions B.
Press down lever operated baffle plate 7, square bar 5 drives interlocking bent plate 2 to rotate clockwise, and block piece A33 is driven by bent plate 2 of interlocking, and makes whole driver plate 31 rotate clockwise (supreme look down); When lever operated baffle plate 7 resets, interlocking bent plate 2 drives B34, and whole driver plate 31 is rotated counterclockwise.
It is to make lateral extension portions A more close to the rotation axis of interlocking bent plate 2 that the vertical extension of block piece A33 is arranged, and then reduces the anglec of rotation of driver plate 31.
Driver plate 31 is provided with slurcam 35 near closing locking baffle plate 1 one end, and described slurcam 35 faces closing locking baffle plate 1 direction.
The operation principle of primary cut-out machinery closing locking device:
