Lower interval.There are two main fixing pipes 127, two wirerope 128 to be each passed through two main fixations for setting in second main fixed plate 126
Pipe 127 is connect with connecting shaft 124.
Fig. 6 is the structural schematic diagram of tripping mechanism 130 in the utility model embodiment;Fig. 7 is the utility model embodiment
In the first lever piece 134 structural schematic diagram.It please refers to Fig. 6 and Fig. 7 and combines aforementioned figures, tripping mechanism 130 is relative to opening
Shutting mechanism is set to the other side of corresponding change-over switch 12, and tripping mechanism 130 includes tripping fixing piece and is movably connected on
First lever piece 134 of tripping fixing piece.In the present embodiment, tripping fixing piece includes that the first tripping fixed plate 131, second is de-
Detain fixed plate 132 and third tripping fixed plate 133.It is provided with card slot 136 in first tripping fixed plate 131, in the present embodiment
In, the middle part of the first lever piece 134 is connected in card slot 136 by main sliding axle 135, and the first lever piece 134 can be around main sliding
Axis 135 rotates, and the trip assembley therefor for making corresponding change-over switch 12 thread off is connected between the both ends of the first lever piece 134
140;When change-over switch 12 is threaded off, change-over switch 12 can not be closed.
The both ends of first lever piece 134 connect with the 110 respective drive mechanism transmissions of other two mutual interlocking gear respectively
It connects.I other words belonging to first of two drive mechanisms of a driving mechanism 120 respectively with other two mutual interlocking gear 110
Lever piece 134 is sequentially connected.In the present embodiment, card slot 136 is strip-shaped hole, is extended along the vertical direction, main sliding axle 135
One end and card slot 136 cooperate, the other end and the first rotatably cooperation of lever piece 134.In the present embodiment, the first tripping is fixed
It is additionally provided with two sliding slots 137 on plate 131, two sliding slots 137 are also strip-shaped hole, are set to two 137 parallel intervals of sliding slot
The two sides of card slot 136.
In the present embodiment, the first lever piece 134 is the plate of diamond shape, and the middle part is provided with a more main sliding axles 135
Bigger through-hole, the first lever piece 134 are sheathed on main sliding axle 135 by the through-hole, the long-diagonal of the first lever piece 134
Both ends tool there are two mounting hole 139, be each provided with a sideslip moving axis 138 in two mounting holes 139, sideslip moving axis 138
One end and sliding slot 137 cooperate, and the drive mechanism (i.e. wirerope 128) that the traction of other two mutual interlocking gear 110 comes is connected to two
The other end of a sideslip moving axis 138.
It (is drawn by swing rod 123 when two drive mechanisms for being connected to same first lever piece 134 do triggering movement
It is dynamic), two drive mechanisms are able to drive the main sliding axle 135 that the first lever piece 134 is arranged and move along the length direction of card slot 136
Dynamic pre-determined distance, to drive trip assembley therefor 140 that corresponding change-over switch 12 is enabled to thread off;When being connected to same first lever piece
When one of 134 two drive mechanisms do triggering movement, according to lever principle, one end of the first lever piece 134 is fulcrum,
When moving downward pre-determined distance by one end that (be subject to the orientation Fig. 6) pulls downwards, middle part (the i.e. main cunning of the first lever piece 134
135 position of moving axis) it is merely able to the half of decline pre-determined distance, therefore the first lever piece 134 is not enough to drive main 135 edge of sliding axle
The mobile pre-determined distance of the length direction of card slot 136, trip assembley therefor 140 are threaded off without the corresponding change-over switch 12 of decree.Such knot
When structure is closed 10 two of them change-over switch 12 of switching system, mutual interlocking gear 110 is de- on another change-over switch 12
Buckle mechanism 130 is triggered, so that the change-over switch 12 is threaded off and can not be closed.
In the present embodiment, two sideslip moving axis 138 can not move in the horizontal direction, in order to enable two sideslip moving axis
138 will not influence the deflection of the first lever piece 134, and in two mounting holes 139 on the first lever piece 134, at least one is
Strip-shaped hole, in this way, by sideslip moving axis 138 and will not be slided when one end of the first lever piece 134 is transmitted structure and pulls and tilt
Slot 137 is influenced and is generated self-locking.
In the present embodiment, the first tripping fixed plate 131, second tripping fixed plate 132 and third tripping fixed plate 133
It is sequentially arranged at intervals setting.Second tripping fixed plate 132 is fixed on corresponding change-over switch 12, and second threads off in fixed plate 132
There are two fixing pipe 144 of threading off, one end of two tripping fixing pipes 144 to be fixed on the second tripping fixed plate 132, the other end for setting
Extend to the first tripping 131 direction of fixed plate, the wirerope 128 of two drive mechanisms pass through from two tripping fixing pipes 144 and
It is connect with sideslip moving axis 138.Tripping fixing pipe 144 is provided with spring between 138 one end of sideslip moving axis and sideslip moving axis 138
145, spring 145 is in squeezed state, can provide restoring force after sideslip moving axis 138 is pulled down into.
In an embodiment of the present invention, it is provided with the second lever piece 142 in third tripping fixed plate 133, the
Two lever pieces 142 can be relative to tripping fixing piece rotation, and in the present embodiment, the second lever piece 142 is the plate body of triangle, takes off
