Description
Technical field
The utility model belongs to a kind of high voltage power distributing cabinet field, is specifically related to a kind of high-voltage power distribution cabinet back door lock device.
Background technology
Along with the develop rapidly of science and technology, the demand of user to electric energy also rises thereupon, and the capacity of power distribution cabinet is also improve year by year, and power distribution cabinet is once beyond thought accident occurs, and consequence is hardly imaginable.Not only affect the daily production of enterprise, cause economic loss, more may damage other people person.Conventional GCS low voltage distribution cabinet door lock is MS705 type, there is lock and cannot fasten, and easily cause casing in transport, lifting or installation process to rock, door-plate opens phenomenon automatically, after operation, easily causes door-plate to be not closed completely, and cabinet degree of protection is not enough; Simultaneously some door lock must be carried with key and can open, not easy to operate.
Utility model content
The technical problems to be solved in the utility model is to provide a kind of high-voltage power distribution cabinet back door lock device, which solves problems of the prior art, simultaneously structure simple, be easy to operation.
In order to solve the problems of the technologies described above, the utility model realizes in the following manner:
A kind of high-voltage power distribution cabinet back door lock device, comprise Rear Door, lower Rear Door, intermediate transverse girder, locking bar and locking device, described upper Rear Door and to be fixedly connected with by hinge between Rear Door with cabinet down, described intermediate transverse girder is between upper Rear Door and lower Rear Door, and intermediate transverse girder overall concave is to the inside of cabinet, the surface of intermediate transverse girder and upper Rear Door and the surface of lower Rear Door form a groove jointly, described locking bar to be arranged on intermediate transverse girder and to run through whole intermediate transverse girder, described locking device is positioned on the inner surface of Rear Door, locking device and locking bar have coordinated the locking of cabinet.
As preferably, described locking bar comprises locking bar front end, locking bar rear end, spring and draw ring, and described locking bar front end is for having inclined-plane, circular arc end angle, and spring is arranged at the inside of locking bar rear end, and is connected with draw ring by bracing wire.
Further, described locking device is the device comprising a tapered plane and screw, the incline direction of tapered plane and the circular arc end angle slopes which match of locking bar front end, and described screw passes through for bolt and is fixed on Rear Door inner surface.
Compared with prior art, the beneficial effect that the utility model has: this door lock assembly structure is simple, between cabinet door and cabinet, energy tight closure, effectively prevents dust, fire, can be widely used in polytype power distribution cabinet.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the close-up schematic view of Fig. 1 at A place;
Fig. 3 is the close-up schematic view of Fig. 1 at B place;
Fig. 4 is the sectional view of Fig. 3 at C-C place.
In figure, each mark is respectively: 1, upper Rear Door, and 2, lower Rear Door, 3, intermediate transverse girder, 4, locking bar, 5, locking device, 41, front end, 42, rear end, 43, spring, 44, draw ring, 51, tapered plane, 52, screw.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, detailed description of the invention of the present utility model is described in further detail.
As shown in Figure 1, a kind of high-voltage power distribution cabinet back door lock device, comprise Rear Door 1, lower Rear Door 2, intermediate transverse girder 3, locking bar 4 and locking device 5, described upper Rear Door 1 and lower Rear Door 2 are fixedly connected with by hinge with between cabinet, described intermediate transverse girder position 3 is between upper Rear Door and lower Rear Door, and intermediate transverse girder overall concave is to the inside of cabinet, the surface of intermediate transverse girder and upper Rear Door and the surface of lower Rear Door form a groove jointly, described locking bar 4 to be arranged on intermediate transverse girder and to run through whole intermediate transverse girder, described locking device 5 is positioned on the inner surface of Rear Door, locking device and locking bar have coordinated the locking of cabinet.
As shown in Figure 2, a kind of locking bar of high-voltage power distribution cabinet back door lock device comprises locking bar front end 41, locking bar rear end 42, spring 43 and draw ring 44, described locking bar front end is for having inclined-plane, circular arc end angle, and spring is arranged at the inside of locking bar rear end, and is connected with draw ring by bracing wire.When staff needs to open cabinet, only need with pulling draw ring, locking bar just down moves under the effect of stressed draw ring; After draw ring to be released, locking bar up moves to origin-location automatically owing to being subject to the impact of spring restoring force, so just achieves the keying of locking bar.
As shown in Fig. 3-4, a kind of high-voltage power distribution cabinet back door lock device locking device is the device comprising a tapered plane 51 and screw 52, the incline direction of tapered plane and the circular arc end angle slopes which match of locking bar front end, described screw passes through for bolt and is fixed on Rear Door inner surface.
The above is only embodiment of the present utility model; again state; for those skilled in the art; under the prerequisite not departing from the utility model principle; can also carry out some improvement to the utility model, these improvement are also listed in the protection domain of the utility model claim.
