At present, the application number on market be 201320869647.9 Chinese patent disclose a kind of knob structure of control and protective switching device, belong to low voltage electrical apparatus technology field.Described control and protective switching device comprises a pedestal, and pedestal is established knob guiding post holes, and described revolves
Button structure comprises knob body, this knob body is configured with knob lead towards the side of pedestal, this knob lead is insinuated in knob guiding post holes the post holes that leads with knob and matches, the hole wall of described knob guiding post holes is configured with the backstop boss on the surface being raised in hole wall, described knob lead is configured with the positive stop lug boss on the surface being raised in knob lead, positive stop lug boss matches with backstop boss, when knob body is in the position of instruction power supply disconnection, described positive stop lug boss and described backstop boss counter stopper, and when knob body is in the ready position of instruction, counter stopper removed by positive stop lug boss and backstop boss.
In such scheme, isolation inserted sheet can pull out from knob body, step bottom it be received into on pedestal and to lead the groove that post holes communicates with knob, but isolation inserted sheet is extracted rear present position instability and is easily misused and promotes back original position, must could realize locking by padlock, use and comparatively bother.
Utility model content
For the deficiency that prior art exists, the purpose of this utility model is to provide a kind of lock-out state Stability Analysis of Structures, anti-misoperation control easy to use and protection switch.
For achieving the above object, the utility model provides following technical scheme: a kind of anti-misoperation control and protection switch, and comprise housing and be arranged on the knob on housing, described housing is provided with stopper slot; Described knob is provided with slot, described slot is after rotating to certain position along with knob, just described stopper slot is arranged, also comprise the isolation inserted sheet inserting slot, be provided with bottom described isolation inserted sheet to coordinate with stopper slot and realize the spacing boss of knob, described isolation inserted sheet is provided with and prevents it from pushing back spacing preiection in slot.
By technique scheme, turning knob, to open position, is extracted after isolating inserted sheet further, boss coordinates with stopper slot, and now knob cannot rotate further, first namely achieves hook knob, the effect preventing its misoperation from rotating, avoids unexpected generation; Spacing preiection and knob realize outer barrier on the other hand, prevent isolation inserted sheet to push back easily in knob, reach the effect that anti-misoperation pushes back isolation inserted sheet, avoid unexpected touching and push back.
The utility model is set to further: be provided with location notch in described slot, and after described isolation inserted sheet inserts slot, spacing preiection coordinates with location notch.
Pass through technique scheme, location notch achieves the accommodation space of spacing preiection, relative locking is achieved after isolation inserted sheet inserts knob completely, avoiding surprisingly vibration or misoperation causes isolation inserted sheet to be released, and the process pushing knob at isolation inserted sheet comprises several change of shape, and spacing preiection slips into slot jack-up knob, knob deformation, spacing preiection slips into location notch, and knob recovers deformation, avoids spacing preiection to be squeezed for a long time effect of attrition outer barrier effect by location notch.
The utility model is set to further: described knob is provided with the first groove, and described isolation inserted sheet is provided with the second groove, and after extracting isolation inserted sheet, the first groove communicates with the second groove and forms the lock-receiving aperture that locks of confession padlock.
Pass through technique scheme, after release isolation inserted sheet, achieving isolation by lock-receiving aperture padlock, inserted sheet is relative with knob locks, and padlock needs to formulate key just can unlock, reach higher fail safe after arranging like this, avoid layman's misoperation and cause accident.
The utility model is set to further: described isolation inserted sheet is provided with the slide block released for it.
Pass through technique scheme, after isolation inserted sheet inserts knob completely, slide block is provided with for the ease of releasing isolation inserted sheet, isolation inserted sheet could be released by slide block, slide block is arranged at isolation inserted sheet bottom, therefore overall structure outer rim transitions smooth, does not have lofty structure, avoids accident collision and causes hand to wound.

Embodiment
Referring to figs. 1 through Fig. 6, the utility model embodiment is described further.
A kind of anti-misoperation control and protection switch, the knob 2 comprising housing 1 and be arranged on housing 1, housing 1 is provided with stopper slot 3; Knob 2 is provided with slot 4, slot 4 is after rotating to certain position along with knob 2, just stopper slot 3 is arranged, also comprise the isolation inserted sheet 5 inserting slot 4, be provided with the boss 51 coordinating with stopper slot 3 and realize knob 2 rotary spacing bottom isolation inserted sheet 5, isolation inserted sheet 5 is provided with and prevents it from pushing back spacing preiection 52 in slot 4; By such setting, turning knob 2, to open position, is extracted after isolating inserted sheet 5 further, boss 51 coordinates with stopper slot 3, and now knob 2 cannot rotate further, first namely achieves hook knob 2, the effect preventing its misoperation from rotating, avoids unexpected generation; Spacing preiection 52 and knob 2 realize outer barrier on the other hand, prevent isolation inserted sheet 5 to push back easily in knob 2, reach the effect that anti-misoperation pushes back isolation inserted sheet 5, avoid unexpected touching and push back.
Preferably, be provided with location notch 41 in slot 4, after isolation inserted sheet 5 inserts slot 4, spacing preiection 52 coordinates with location notch 41; By such setting, location notch 41 achieves the accommodation space of spacing preiection 52, relative locking is achieved after isolation inserted sheet 5 inserts knob 2 completely, avoiding surprisingly vibration or misoperation causes isolation inserted sheet 5 to be released, the process pushing knob 2 at isolation inserted sheet 5 comprises several change of shape, spacing preiection 52 slips into slot 4 jack-up knob 2, knob 2 deformation, spacing preiection 52 slips into location notch 41, knob 2 recovers deformation, avoids spacing preiection 52 to be squeezed for a long time effect of attrition outer barrier effect by location notch 41.
