Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 is the overall structural representation of explosion-proof frequency converter case;
Fig. 2 is Double-quick-opening-door interlocking gear and change over switch connection diagram;
Fig. 3 is Double-quick-opening-door interlocking gear front view.
Embodiment
As shown in Figure 1, 2, 3, a kind of Double-quick-opening-door explosion-proof frequency converter casing, comprise: Double-quick-opening-door interlocking gear 1, change over switch 2, card article 3, explosion-proof casing 4, chamber door 5, operating grip 6, described explosion-proof casing 4 is provided with two chamber door 5 opening symmetry, two opening between symmetrical chamber door 5 is provided with the interlocking gear 1 be connected with change over switch 2., on chamber door, be wherein provided with the passive alternating current-direct current electrification display of observation and explosion-proof frequency converter electriferous state.
In figure, Double-quick-opening-door interlocking gear (1), change over switch (2), card article (3), explosion-proof casing (4), chamber door (5) and operating grip (6) form quick operating valve interlocking gear jointly.
In figure, Double-quick-opening-door linkage structure (1) is connected by middle connecting axle with change over switch (2), rotates connection and shutoff that change over switch knob (1-3) can realize main circuit.When explosion-proof frequency converter normally works, the switching knob (1-3) above conversion Double-quick-opening-door linkage structure (1) is opened, and explosion-proof casing (4) is locked.During to open quick operating valve explosion-proof frequency converter explosion-proof casing (4), first change over switch knob (1-3) is rotated, powered-down, tooth bar (1-2), (1-5) indentation up and down simultaneously, move left and right operating grip (6), drive camming movement that chamber door (5) is moved up and depart from card article (3), then to inner rotary left and right operating grip (6), chamber door (5) is opened.If do not have powered-down, then upper and lower tooth bar (1-2) (1-5) limits on chamber door (5) and moves, and chamber door (5) cannot be opened.In addition, this linkage structure is equally applicable to single quick operating valve explosion-proof casing, only need remove one-sided chamber door block (1-1) and tooth bar (1-2).
