Embodiment
Consult shown in Fig. 1 and Fig. 2, a kind of high-voltage board back door interlocking mechanism of the present utility model, this interlocking gear by being arranged on the jam plate 1 of visiting on door-plate on high-voltage board rear side, be arranged on the Xiamen jam plate 2 on lateral lower door plate and the linkage assemblies 4 being arranged on high-voltage board rear side mounting rail 3 after high-voltage board and form, on jam plate 1, be provided with the guiding locking notch 1a corresponding with linkage assemblies 4 visiting, on Xiamen jam plate 2, be provided with the guiding breach 2a corresponding with linkage assemblies 4; Described linkage assemblies 4 by being fixed on guide holder 4a on mounting rail 2, the upper chain transfer bar mechanism 4d and the lower chain transfer bar mechanism 4e that are vertically located in two guiding pole 4b on guide holder 4a, are arranged on the resetting device 4c between guiding pole 4b and guide holder 4a and are connected to two guiding upper and lower two ends of pole 4b form; The fixed head that guide holder 4a is arranged by two block gaps forms.In the time of cabinet Men Weiguan, the openend of guiding locking notch 1a is relative with upper chain transfer bar mechanism 4d, and openend and the lower chain transfer bar mechanism 4e of guiding breach 2a stagger; In the time that upper door-plate cuts out, the openend of guiding breach 2a is relative with lower chain transfer bar mechanism 4e.And, for protecting linkage assemblies 4 not to be subject to the damage of external object, prevent that it from wrecking, on the cabinet in linkage assemblies 4 outsides, be provided with protective baffle plate 7, on protective baffle plate 7, be provided with and the corresponding connecting hole 7a of jam plate 1 and Xiamen jam plate 2 that visits; Described guide holder 4a is arranged between mounting rail 3 and protective baffle plate 7.
Particularly, described guiding locking notch 1a is by the targeting port 1b towards having a down dip and form targeting port 1b and locking mouthful 1c mutual conduction with the locking mouth 1c of vertical setting; Described guiding breach 2a is towards the oblique breach having a down dip.Targeting port 1b is identical with the incline direction of guiding breach 2a, and by calculating in advance installation site, make to lead locking notch 1a and guiding breach 2a can coordinate the orderly close-down of realizing upper and lower door dexterously, avoid occurring violation operation.Simultaneously, described resetting device 4c by be connected to two backstay 4f between guiding pole 4b and be connected to backstay 4f and guide holder 4a between back-moving spring 4g form, instantly when door-plate is opened, linkage assemblies 4 rises under the effect of back-moving spring 4g, chain transfer bar mechanism 4d is deviate from from locking mouthful 1c, the unlatching of door-plate in realization.
Further, when upper door-plate and lower door-plate are closed and opened for convenience, upper chain transfer bar mechanism 4d and lower chain transfer bar mechanism 4e are caused to wearing and tearing, the upper chain transfer bar mechanism 4d described in the present embodiment and lower chain transfer bar mechanism 4e form by fulcrum 5 and the rotating cylinder 6 that is enclosed within fulcrum 5 peripheries.Adopt rolling structure, can avoid to greatest extent the wearing and tearing of parts, effectively increase the service life.
Consult shown in Fig. 3 to Fig. 5, in the time that not upper and lower door-plate does not all cut out, upper door-plate can freely cut out, and lower door-plate is because openend and the lower chain transfer bar mechanism 4e of guiding breach 2a stagger and cannot realize and normally closing, and reaches the object that prevents that lower door-plate from first cutting out than upper door-plate.When use, must first close door-plate, linkage assemblies 4 is moved down under the effect of targeting port 1b, the openend of the breach 2a that makes to lead is relative with lower chain transfer bar mechanism 4e, could realize closing of lower door-plate.In the time closing lower door-plate, upper chain transfer bar mechanism 4d enters in locking mouthful 1c, and door-plate cannot be opened, and only, after the normal unlatching of lower door-plate, upper door-plate could be opened.Thereby with the structure of advantages of simple, realize the order of high-voltage board rear side upper-lower door and opened, protected power network safe operation, guaranteed equipment and personal safety.
Above illustrated embodiment is preferred embodiments of the present utility model, only be used for facilitating explanation the utility model, not the utility model is done to any pro forma restriction, under any, in technical field, have and conventionally know the knowledgeable, if not departing from the scope of technical characterictic that the utility model is carried, utilize technology contents that the utility model discloses to do the local equivalent embodiment that changes or modify, and do not depart from technical characterictic content of the present utility model, all still belong in the scope of the utility model technical characterictic.
