Embodiment
With reference to accompanying drawing 1-5.
A kind of switch cabinet shutter locking device disclosed in the utility model, comprises fixed head 1, jam plate 2, supporting bracket 3, pressing plate 4, limit shaft 5, jam plate driving shaft 6, pressing plate driving shaft 7, axle sleeve 8, spring 9.Fixed installation hole 11 is provided with bottom described fixed head 1, described fixed head about 1 two ends are symmetrically arranged with the square hole 12 for jam plate activity, described fixed head about 1 two ends are symmetrically arranged with spring hanging hole 13, described fixed head 1 upper end is provided with the first boss 14 be connected with supporting bracket, described supporting bracket 3 is provided with the hole 34 be connected with limit shaft, described supporting bracket 3 is provided with the open slot 33 slided for jam plate driving shaft, described supporting bracket 3 is provided with lock-receiving aperture 32, described pressing plate 4 is provided with the first connecting hole 421 be connected with pressing plate driving shaft, described pressing plate 4 is provided with the second spacing hole 424, pressing plate is provided with the first lock-receiving aperture 422 and the second lock-receiving aperture 423, described pressing plate 4 is provided with the slotted hole 425 that jam plate driving shaft slides, described jam plate 2 lower end is provided with the screw mounting hole 222 be connected with spring, described jam plate 2 front end is provided with the second boss 21 coordinated with valve connecting plate, described pressing plate driving shaft 7 is fixed on pressing plate 4 through axle sleeve 8, described axle sleeve 8 can rotate around driving shaft 7.
