When DC button is pressed, DC locking key promotes push rod, and press after the closed DC switch that puts in place until DC button, push rod and AC locking key touch, now because the AC locking key of AC button and push rod touch, once press AC button, then DC button pushed away from the position of closed DC switch, DC switch opens, and AC button not yet can reach the position of closed AC switch, if DC button have employed locking device, namely DC button cannot unartificially be upspring after being pressed, then AC button cannot be pressed.In like manner, when AC button is pressed, AC locking key promotes push rod, press after the closed AC switch that puts in place until AC button, push rod and DC locking key touch, now because the DC locking key of DC button and push rod touch, once press DC button, then AC button pushed away from the position of closed AC switch, AC switch opens, and DC button not yet can reach the position of closed DC switch, if AC button have employed locking device, namely AC button cannot unartificially be upspring after being pressed, then DC button cannot be pressed.If press AC button and DC button simultaneously, then due to the existence of push rod, AC button and DC button all can not reach the position of closed AC switch or DC switch.In sum, DC locking key, AC locking key and push rod three part, by the setting of mutual distance and change, form and make DC button and AC press interlock, and then make the switch interlock device of DC switch and AC switch interlock.
Further, housing comprises left cover and right cover, and left cover, right cover can detain mutually formation inner chamber, thus is convenient to produce installation and later maintenance.
Further, be provided with division board in inner chamber, division board both sides are located at respectively by DC switch and AC switch, cause short circuit or other faults to prevent aprowl AC circuit and DC circuit from touching.
Further, support is fixed by screws on housing, and support is provided with through hole, and push rod through through hole, thus makes push rod stably be between AC locking key and DC locking key.
Further, be provided with power supply indicator board outside housing, power supply indicator board is electrically connected respectively with DC switch, AC switch, and when DC switch or AC switch close, indicator light corresponding on power supply indicator board lights, and personnel can learn whether DC button or AC button have pressed and put in place.
After adopting technique scheme, the utility model tool has the following advantages:
By arranging push rod between two place's shift knobs, make the same time only have place's switch to be closed, simple and reliable for structure, cost is low.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the utility model is described in further detail:
Fig. 1 is the explosive view of a kind of embodiment of the utility model.
Embodiment
Attachedly Figure 1 shows that a kind of embodiment of the present utility model.
A kind of alternating current-direct current interlocking-type switch enclosure, comprise housing, housing comprises left cover 10 and right cover 20, left cover 10, right cover 20 can detain formation inner chamber mutually so that produce installation and later maintenance, the DC button 12 of closed DC switch 11 when being provided with DC switch 11 in inner chamber and pressing, AC switch 21 and the AC button 22 closing AC switch 21 when pressing, left cover 10 and right cover 20 are respectively equipped with and can pass DC button 12, the handle hole 30 of AC button 22, support 31 is also provided with in inner chamber, support 31 is provided with push rod 32, push rod 32 can slide along its length on support 31, support 31 is fixed by screws on housing, support 31 is provided with through hole 34, push rod 32 is through through hole 34, DC button 12 is provided with DC locking key 13, DC locking key 13 is positioned on the length direction of push rod 32, DC locking key 13 promotes push rod 32 and touches with AC locking key 23 when DC button 12 is pressed, AC button 22 is provided with AC locking key 23, AC locking key 23 is positioned on the length direction of push rod 32, AC locking key 23 promotes push rod 32 and touches with DC locking key 13 when AC button 22 is pressed, push rod 32 is stably between AC locking key 23 and DC locking key 13.
