Embodiment
In order that the object, technical solutions and advantages of the present invention are clearer, below in conjunction with the accompanying drawings with specific embodiment pair
The present invention is described in detail.
The interlock 100 of the change-over switch shown in Fig. 1 to Fig. 2 is referred to, change-over switch is installed on（Non- label）Behaviour
At the intermediate space for making mechanism 200.The interlock 100 of the change-over switch includes top 1, is in center pair with the top 1
Claim the bottom 2 of structure setting and be arranged at the top 1 and the connecting pin 3 at the Central Symmetry of the bottom 2.
The top 1 includes upper arm 11 and the upper protuberance of arc extension is continued up from the upper end of the upper arm 11
12。
The upper arm 11 includes the upper arresting pin 111 positioned at the upper end of the upper arm 11, the lower end positioned at the upper arm 11
Upper reset spring 112 and the upper hopper chute 113 positioned at the middle part of upper arm 11.
The bottom 2 includes underarm 21 and continues the lower protuberance of arc extension downwards from the lower end of the underarm 21
22。
The underarm 21 is including the lower limit pin 211 positioned at the lower end of the underarm 21, on the underarm 21 and leans on
The lower back-moving spring 212 and the gliding groove 213 positioned at the middle part of underarm 21 of the nearly connecting pin 3.
The operating mechanism 200 includes the upper control unit 4 and control change-over switch of the conventional side power supply of control change-over switch
Prepped side power supply lower control unit 5.The upper control unit 4 includes epipleural 41, upper cantilever 42, upper drive shaft 43 and upper de-
Button bar 44；The lower control unit 5 includes lower side panel 51, lower cantalever 52, lower drive shaft 53 and lower release lever 54.
In the present invention, the upper control unit 4 is fixed on the top 1, and the lower control unit 5 is fixed in the bottom 2.
The two ends of the upper reset spring 112 are connected with the upper arm 11 and the epipleural 41 respectively, the lower back-moving spring 212
Two ends be connected respectively with the underarm 21 and the lower side panel 51.
In the present invention, when the upper control unit 4 closes conventional side power supply, the upper drive shaft 43 drives described outstanding
Arm 42 is rotated, and promotes the top 1 and the bottom 2 along the upper hopper chute 113 around described in the rotation process of upper cantilever 42
Connecting pin 3 is rotated.The lower protuberance 22 pushes down the lower release lever 54 so that the lower release lever 54 is not moved, and is made standby
Do not closed a floodgate with side power supply.When the upper control unit 4 of the operating mechanism 200 disconnects conventional side power supply, the upper cantilever 42
Original position is gone back to, the top 1 and the bottom 2 are in the upper reset spring 112 and the common work of the lower back-moving spring 212
Set back under.
When the lower control unit 5 closes prepped side power supply, the lower drive shaft 53 drives the lower cantalever 52 to rotate, institute
State and promote the top 1 and the bottom 2 along the gliding groove 213 around 3 turns of the connecting pin in the rotation process of lower cantalever 52
It is dynamic.The upper protuberance 12 pushes down the upper release lever 44 so that the upper release lever 44 is not moved, and makes conventional side power supply not
Close a floodgate.When the lower control unit 5 of the operating mechanism 200 disconnects prepped side power supply, the lower cantalever 52 goes back to original position, institute
State top 1 and the bottom 2 and recover former under the collective effect of the upper reset spring 112 and the lower back-moving spring 212
Position.
When change-over switch is in an intermediate position, the upper control unit 4 and conventional side power supply, the lower control unit 5 with it is standby
When side power supply is in gate-dividing state, the interlock 100 of the change-over switch is in initial position.
In the present invention, the top 1 and the bottom 2 are integrated punching shapings, simple to operate, with low cost.
In summary, the interlock 100 and change-over switch of change-over switch of the present invention are by promoting the top 1 and described
The switching of different electrical power is connected in bottom 2 with being slided in the gliding groove 213 in the upper hopper chute 113 to realize, and is not take up sky
Between, the gap of itself of operating mechanism 200 is fully utilized to install and work, small volume, it is easy to accomplish, it is with low cost.
The above embodiments are merely illustrative of the technical solutions of the present invention and it is unrestricted, although with reference to preferred embodiment to this hair
It is bright to be described in detail, it will be understood by those within the art that, technical scheme can be modified
Or equivalent substitution, without departing from the spirit and scope of technical solution of the present invention.
