Description
Technical field
The invention belongs to power consumption control apparatus field, is related to a kind of switch of locking locking apparatus.
Background technology
Common switch, the rotation of knob stress, exportable corresponding function when corresponding to different gears, but for some work(
The black out lamp swtich that can be not allow in maloperation, such as military vehicle, in addition to the signal light control function need to civilian vehicle,
Signal light control function when also needing to possess operation under air defense pattern, both of which can not arbitrarily switch, and need to have interlock function, prevent
Only maloperation.Therefore, some switching requirements have conducting lock function, i.e., after switch conduction, are locked, and are that switch holding is led
Logical state.The locking mechanism of the existing switch for realizing conducting locking is typically made up of lock knob, guiding bar and push rod.Pass through guiding
The projection of bar upper end coordinates the mutually locking for realizing push rod and guiding bar with the groove on push rod.The shortcomings that this mechanism is switch
Lock knob directly transmitted acted in guiding bar due to the thrust for the push rod spring for acting on push rod in the locked state, then pass through
Guiding bar passes to power on lock knob so that lock knob banking, is switched after being attached on casing, it will be apparent that secundly so that
Lock knob is not or not installation casing center.In view of the above-mentioned problems, prior art is improved, as patent CN201410351000 is provided
One kind switch, the switch include：Switch case, switch case have accommodating chamber；Push-rod assembly, push-rod assembly include push rod, pushed away
Bar is movably disposed in accommodating chamber along accommodating chamber；Latch-up structure, latch-up structure are stretched into accommodating chamber, and latch-up structure has resistance
The latched position that throw-out lever moves to outside accommodating chamber；Lock slider, lock slider are movably disposed along the moving direction of push rod
On latch-up structure, when latch-up structure is in the locked position, lock slider is pushed against between push rod and switch case and backstop pushes away
Bar moves.It can prevent that cage knob tilts after switching locking by the switch.But the structure is simultaneously unreasonable, using effect is simultaneously paid no attention to
Think.
