Specific embodiment
1-9 describes an embodiment of the present invention with reference to the accompanying drawing.
For the hard interlocking gear of machinery of breaker of switch cabinet, including the operation handle 1 and rotation connecting lever in operating mechanism
2,2 one end of rotation connecting lever rotational installation is on switchgear 3 and rotation 2 one end end of connecting lever and is located at outside switchgear 3
Operation handle 1 is fixedly connected, and 2 other end of rotation connecting lever is located at 3 inside of switchgear and rotates 2 other end end of connecting lever and connection
Motivation structure one end is hinged, and the linkage mechanism other end and the tripping for 4 upper end of breaker body being set to inside switchgear 3 are chain
Axis 5 is fixedly connected, and drives linkage mechanism to complete to the effective of chain axis 5 that trip by rotation connecting lever 2 by rotation operation handle 1
It is chain；Specifically, the linkage mechanism includes that connecting plate 6, rotating bracket 7, adjustable plate 8 and terminal execute plate 9, the rotating bracket
7 is L-shaped structures and the rotational installation of 7 side plate of rotating bracket is in switchgear 3, described 6 one end of connecting plate and rotation 2 other end of connecting lever
Hinged and 6 other end of connecting plate and 7 side plate end of rotating bracket are hinged, another side plate of the rotating bracket 7 and 8 upper end of adjustable plate
Hinged and 8 lower end of adjustable plate and terminal execution 9 upper end of plate are hinged, and the terminal executes 9 lower end of plate and is fixedly connected on breaker sheet
On the chain axis 5 of the tripping of 4 upper end of body；Specifically, being formed with multiple and rotating bracket 7 and terminal execution in 8 plate face of adjustable plate
The adjustment hole 10 that hinge hole 11 on plate 9 is adapted to, and the hinge hole 11 that rotating bracket 7 and terminal execute in 9 two sides plate face of plate is set
Have multiple.
In this structure, make to rotate the rotation of connecting lever 2 by rotating operation handle 1, rotation connecting lever 2 drives connecting plate 6 to turn to rotate
The center of rotation of arm 2 moves in a circle, and the circular motion of connecting plate 6 drives rotational installation to make thick stick in the rotating bracket 7 on switchgear 3
Bar movement, rotating bracket 7 do lever motion and adjustable plate 8 are driven to move up and down, and adjustable plate 8 drives terminal to execute plate 9 and does circumference
Movement, terminal execute plate 9 and are fixed on the chain axis 5 of tripping, so that the chain axis 5 of tripping be driven to rotate, by adjusting adjustable plate 8 with
Rotating bracket 7 and terminal execute the link position of plate 9, and so as to adjust the movement angle for the chain axis 5 that trips, the chain axis 5 that trips is
Well known circuit breaker internal interlocking gear realizes tripping, steel wire is effectively substituted and connects mode, eliminates fixation with steel wire and loosely takes off
The risk for leading to the chain failure of breaker of switch cabinet is fallen, circuit breaker internal interlocking gear is well-known technique, and this will not be repeated here.
The technical program inside switchgear 3 by being arranged for the rotation connecting lever 2 and breaker in attended operation mechanism
The linkage mechanism of the chain axis 5 of tripping of 4 upper end of ontology, previous steel wire connection type is substituted by hard interlocking gear, eliminates steel
Silk, which is not fixed firmly to fall off, leads to the risk of the chain failure of breaker of switch cabinet, and the chain axis 5 of tripping of 4 upper end of breaker body turns
Dynamic angle can be adjusted by linkage mechanism, strong flexibility, and it is reliable on the chain axis 5 of tripping to ensure that linkage mechanism acts on
