Accompanying drawing explanation
Fig. 1 is structural representation of the present invention;
Fig. 2 is the structural representation after removing spring operating mechanism and fuse;
In figure: 1-first connecting rod, 2-second connecting rod, 3-third connecting rod, 4-double leval jib, 5-the 5th connecting rod, 10-spring operating mechanism, 20-fuse.
Embodiment
In order to make object of the present invention, technical scheme and advantage clearly understand, below in conjunction with accompanying drawing, the present invention is further elaborated.
As Fig. 1, shown in Fig. 2, fuse tripping interlocking device disclosed by the invention, comprise first connecting rod 1, second connecting rod 2, third connecting rod 3, double leval jib 4, 5th connecting rod 5, spring operating mechanism 10 and 3 fuses 20, first connecting rod 1, second connecting rod 2, one end of third connecting rod 3 is all fixedly connected with the same side of double leval jib 4, one end of 5th connecting rod 5 and the end face pinned connection of double leval jib 4, first connecting rod 1, second connecting rod 2, the other end of third connecting rod 3 connects the trigger mechanism of 3 fuses 20 respectively, the trip shaft of the other end linking springs operating mechanism 10 of the 5th connecting rod 5, the centre position of first connecting rod 1, second connecting rod 2, third connecting rod 3 is equipped with fixed pivot, and first connecting rod 1, second connecting rod 2, third connecting rod 3 are rotationally connected with fixed pivot, 3 fuses 20 are installed in isosceles triangle, third connecting rod 3 is between first connecting rod 1, second connecting rod 2, the other end of first connecting rod 1, second connecting rod 2 is positioned at the top of double leval jib 4, the other end of third connecting rod 3 is positioned at the below of double leval jib 4, and double leval jib 4 raises up with the connecting portion of third connecting rod 3.
Actual when using, when fuse trigger promotes first connecting rod 1, second connecting rod 2, third connecting rod 3 any one, first connecting rod 1, second connecting rod 2 in the direction of arrows time rotate against pin, third connecting rod 3 connecting rod in the direction of arrows time rotate along pin.The rotation of first connecting rod 1, second connecting rod 2, third connecting rod 3 all promotes double leval jib 4 and turns clockwise in the direction of arrows, now pulls the 5th connecting rod 5 to move downward in the direction of arrows.
5th connecting rod 5 is connected with the trip shaft of spring operating mechanism, and the trigger action of fuse 20 is delivered to trip shaft by first connecting rod 1, second connecting rod 2, third connecting rod 3, double leval jib 4, the 5th connecting rod 5, and control spring operating mechanism 10 quick acting switching-off operates.
Double leval jib 4 rotates clockwise and will connecting rod 5 be pulled to move downward, driving mechanism trip shaft.It is consistent that gravity and the double leval jib 4 of the 5th connecting rod 5 rotate clockwise motive force direction, effectively can save the power of fuse 20 trigger, make trip gear efficiency higher.
Certainly; the present invention also can have other various embodiments; when not deviating from the present invention's spirit and essence thereof; those of ordinary skill in the art can make various corresponding change and distortion according to the present invention, but these change accordingly and are out of shape the protection range that all should belong to the claim appended by the present invention.
