Description
Technical field
The utility model relates to the anti-snap close locking device of a kind of electric substation high-tension switch cabinet five, belong to the secure latch technical field of electric substation's high-tension switch cabinet.
Background technology
At present, the high-voltage switch cabinet door of electric substation all will install anti-misoperation locking device substantially, but existing back door of high-tension switch cubicle plate is still installed with original holding screw, staff is in maintenance process, time have the holding screw gone to the wrong way interval or tear high voltage cabinet door by mistake open, thus initiation electric shock accidents, its reason is also to lack effectively in prior art, reliable locking device, simultaneously because the screw bearing on back door of high-tension switch cubicle plate has groove mostly, therefore existing general locking closes device by mistake, all be not suitable with and install at this, thus there are some potential safety hazards, easily cause the generation of the accidents such as misoperation.
Summary of the invention
The purpose of this utility model is the deficiency overcoming prior art existence, and provide a kind of structure simple, easy to use, reliable, good looking appearance, can to the various anti-snap close locking devices of electric substation's high-tension switch cabinet five needing the high-tension switch cabinet of operation to carry out effective management and control in electric substation.
The purpose of this utility model has been come by following technical solution, the anti-snap close locking device of a kind of electric substation's high-tension switch cabinet five, it comprises a screw fastening on back door of high-tension switch cubicle plate, described Rear Door is also fastened with by described screw the U-shaped positioning seat sheet that both sides are vertical tabs, wherein the end limit hinge of a vertical tabs has one turning and cover the cover plate of the vertical tabs in U-shaped positioning seat sheet both sides, another vertical tabs evagination have one with lockhole, lacing film that the slotted eye that can offer from cover plate stretches out.
As preferably: described cover plate both sides are also connected to two lateral plates in vertical configuration of one, and two lateral plates can be interposed in U-shaped positioning seat sheet both sides when cover plate covers the vertical tabs in U-shaped positioning seat sheet both sides, U-shaped positioning seat sheet and cover plate is made to form the cavity of enclose inside.
As preferably: the internegative of described U-shaped positioning seat sheet by the screw fastening of hexagonal cylindrical head in described employing on the Rear Door of high-tension switch cabinet.
It is simple that the utility model has structure, easy to use, reliable, good looking appearance, can carry out the features such as effective management and control to the various high-tension switch cabinets of operation that need in electric substation.
Accompanying drawing explanation
Fig. 1 is five anti-snap close unlocking structure schematic diagrames described in the utility model.
Fig. 2 is five anti-snap close blocking schematic diagrames described in the utility model.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in detail: shown in Fig. 1, the anti-snap close locking device of a kind of electric substation described in the utility model high-tension switch cabinet five, it comprises a screw 2 fastening on back door of high-tension switch cubicle plate 1, described Rear Door 1 is also fastened with by described screw 2 the U-shaped positioning seat sheet 4 that both sides are vertical tabs 3, wherein the end limit bearing pin 5 of a vertical tabs 3 is hinged with one turning and cover the cover plate 6 of the vertical tabs 3 in U-shaped positioning seat sheet both sides, another vertical tabs 3 evagination has one with lockhole 7, the lacing film 9 that the slotted eye 8 can offered from cover plate 6 stretches out.
Shown in figure, cover plate 6 both sides described in the utility model are also connected to symmetry two lateral plate 10 in vertical configuration of one, and two lateral plates 10 can be interposed in U-shaped positioning seat sheet 4 both sides when cover plate 6 covers the vertical tabs 3 in U-shaped positioning seat sheet 4 both sides, U-shaped positioning seat sheet 4 is made to form with cover plate 6 internal cavities closed, become five safe anti-snap close blockings, in lockhole 7, locking is realized, as shown in Figure 2 with lockset 11 interlocking.
The internegative of U-shaped positioning seat sheet 4 described in the utility model is fastened on the Rear Door 1 of high-tension switch cabinet by the screw 2 of hexagonal cylindrical head in described employing.
The utility model when locking is installed, do not need to construction high-tension switch cabinet have a power failure after install, be specially adapted to the electric substation of having gone into operation; The switch cubicle of band high-tension electricity is a little sent to carry out improving and improvement and installation of five anti-devices.
