[embodiment]
Explanation the present invention that can be detailed by the following examples, discloses object of the present invention and is intended to protect all technological improvements in the scope of the invention,
High-voltage switch cabinet door unnormal unlocking warning device described in 1 or 2 by reference to the accompanying drawings, comprise cabinet door 15, doorframe 16, flap 14, telescopic mast 9 and alarm 2, in the outside of flap 14, be provided with snap close 12, the inside face of flap 14 is connected with one end of connecting link 10, the other end of connecting link 10 is provided with hole enlargement ring 11, connecting link 10 is through in the perforation 13 arranging on cabinet door 15, on in the reaming that described hole enlargement ring 11 arranges in 13 inner sides of boring a hole, outer rim top at flap 14 is provided with gap 18, in described gap 18 1 sides, is provided with catch 17 outwardly; The inner face of described alarm 2 is provided with holder 1, holder 1 profit is screwed on the cabinet door 15 on flap 14 tops, alarm 2 outer lower portion are provided with trigger board 4, the outer end of telescopic mast 9 is through in trigger board 4, the middle part of telescopic mast 9 is provided with baffle plate 3, telescopic mast 9 between described baffle plate 3 and trigger board 4 is provided with spring 8, and the inner of telescopic mast 9 withstands on doorframe 16 through after cabinet door 15; Close baffle plate 3 bottoms of described telescopic mast 9 are provided with groove 7, the gap 18 of the corresponding flap 14 of described groove 7 or flap 14; In the outer end of telescopic mast 9, be provided with compressing tablet 6, at compressing tablet 6, be provided with the electrode 5 of corresponding trigger board 4 top electrodes 5, the connection of described compressing tablet 6 and described alarm 2 power supplys after electrode 5 in trigger board 4 is connected, described alarm 2 comprises that any one or audible alarm in audible alarm and light alarm is in conjunction with light alarm.
Implement high-voltage switch cabinet door unnormal unlocking warning device of the present invention, the present invention is when cabinet door 15 normal locking, need to be by flap 14 rotation so that the knocker locking cabinet door 15 coordinating with snap close 12 directions, doorframe 16 heads on telescopic mast 9 and makes the electrode 5 of trigger board 4 and, compressing tablet 6 opposite faces separated like this; During operation, utilize the gap 18 arranging on flap 14, after staff opens, rotating flap 14 makes flap 14 proceed to the groove 7 of telescopic mast 9, stop that telescopic mast 9 moves, holding like this cabinet door 15 just can trigger alarm device 2, when if student opens cabinet door 15, the corresponding telescopic mast 9 of gap 18 of flap 14, by the effect of spring 8, electrode 5 on compressing tablet 6 is connected with the electrode 5 in trigger board 4, alarm just can give the alarm, make student or there is no the people of professional knowledge away from high-tension switch cabinet, the risk that has reduced student or do not had the people of professional knowledge to be hurt; The present invention has expanding function, and when occurring that malice is opened cabinet door 15, same telescopic mast 9 utilizes the effect of spring 8, gives the alarm.
Part not in the detailed description of the invention is prior art.
