A kind of low-tension switch cabinet of convenient maintenance
Technical field
The present invention relates to switch cubicle technical field, in particular to a kind of low-tension switch cabinet of convenient maintenance.
Background technology
At present, electric elements in switch cubicle are mounted on one piece of mounting panel mostly, and mounting panel is fixed on the backboard of cabinet again, or are directly arranged in cabinet by electric elements, no matter be which kind of mode is installed, when daily maintenance or breakdown maintenance, all needing operating personnel by probeing into cabinet above the waist, maintenance could be carried out to the device in cabinet and checking, and operating personnel can only be held, very inconvenient, bring sense of discomfort to operating personnel, also have impact on maintenance work efficiency.
Summary of the invention
The object of the present invention is to provide a kind of low-tension switch cabinet of convenient maintenance, to solve the problem.
For realizing the object of the invention, the technical scheme adopted is: a kind of low-tension switch cabinet of convenient maintenance, the cabinet door comprise cabinet, being rotationally connected with cabinet, be positioned at cabinet inner bottom part and the slide plate arranged that slides, the driving mechanism driving slide plate to slide to cabinet reveal, the components and parts mounting panel be positioned on slide plate; On the base plate of cabinet, the left and right sides is provided with the track of L shape, and slide plate is positioned in the L shape right-angle surface of two tracks, and is provided with brass sheet between slide plate and track, brass sheet is placed with filler opening, is embedded with graphite in filler opening; The top of slide plate is provided with and limits its resupinate spacing pressing plate; The bottom surface of slide plate is provided with projection, and the base plate of cabinet is provided with the stopper corresponding with described projection; Slide plate offers the chute that the direction of cabinet door when closing with cabinet door is consistent, driving mechanism comprises drive block and drive rod, and drive block is positioned at chute, and one end and the drive block of drive rod are hinged, and the other end is fixedly connected with cabinet door.
Further, be rotationally connected by rotating shaft and the axle sleeve be set in outside rotating shaft between described cabinet door and cabinet, rotating shaft is positioned on cabinet, and axle sleeve is positioned on cabinet door; The cabinet door link of drive rod is fixed on axle sleeve.
Further, described spacing pressing plate is the strip pressing plate arranged along two siding tracks, and is bolted on track.
The invention has the beneficial effects as follows, when opening cabinet door, drive block is driven to move in the chute of slide plate by drive rod, active force to cabinet reveal is produced to slide plate, drive slide plate along rail moving, thus the distance furthered between components and parts mounting panel and operator, better operation is installed or maintenance, when closing Over-The-Counter door, drive drive block that slide plate is moved in cabinet by drive rod equally, achieve the automatic movement that components and parts mounting panel follows the keying of cabinet door, do not need again mounting panel to be fixed on cabinet, and do not need to probe into again in cabinet during maintenance, more convenient, improve operating efficiency, simultaneously by projection and stopper, the sliding stroke setting slide plate is set, convenient control.And brass sheet is embedded in graphite, slide plate is reciprocatingly slided smoothly, structure is simple, and cost is low, and spacing pressing plate can prevent run-off the straight upset in slide push-pull process, ensure that the reliability of bascule.
Accompanying drawing explanation
Fig. 1 is the front view of the cabinet inner structure of the low-tension switch cabinet of convenient maintenance provided by the invention;
Fig. 2 is the vertical view cutaway drawing of the low-tension switch cabinet of convenient maintenance provided by the invention.
Embodiment
Also by reference to the accompanying drawings the present invention is described in further detail below by specific embodiment.
Fig. 1, Fig. 2 show the low-tension switch cabinet of convenient maintenance provided by the invention, the cabinet door 2 comprise cabinet 1, being rotationally connected with cabinet 1, be positioned at cabinet 1 inner bottom part and the slide plate 3 arranged that slides, the driving mechanism driving slide plate 3 to slide to cabinet reveal, the components and parts mounting panel 4 be positioned on slide plate 3; On the base plate of cabinet 1, the left and right sides is provided with the track 11 of L shape, and slide plate 3 is positioned in the L shape right-angle surface of two tracks 11, and is provided with brass sheet 12 between slide plate 3 and track 11, brass sheet 12 is placed with filler opening 13, is embedded with graphite in filler opening 13; The top of slide plate 3 is provided with and limits its resupinate spacing pressing plate 31; The bottom surface of slide plate 3 is provided with projection 35, the base plate of cabinet 1 is provided with the stopper 36 corresponding with projection 35; Slide plate 3 offers the chute 32 that the direction of cabinet door 2 when closing with cabinet door 2 is consistent, driving mechanism comprises drive block 33 and drive rod 34, and drive block 33 is positioned at chute 32, and one end and the drive block 33 of drive rod 34 are hinged, and the other end is fixedly connected with cabinet door 2.
Projection 35 is two, and symmetrical relative to the center line of cabinet 1 length direction, makes slide plate 3 slide into projection 35 when encountering stopper 36, more stable, avoids discontinuity and rocks.
Be rotationally connected by rotating shaft 5 and the axle sleeve 6 be set in outside rotating shaft 5 between cabinet door 2 and cabinet 1, rotating shaft 5 is positioned on cabinet 1, and axle sleeve 6 is positioned on cabinet door 2, and the two ends being specially rotating shaft 5 are fixed on cabinet 1, on the axis body between the two ends that axle sleeve 6 is set in rotating shaft 5; The cabinet door link of drive rod 34 is fixed on axle sleeve 6.Such drive rod 34 is fixedly connected with cabinet door 2 by axle sleeve 6, and when rotating cabinet door 2, drive rod 34 also can be followed cabinet door 2 phase countershaft together with axle sleeve and be rotated, thus drives drive block 33 to slide, and drives slide plate 3 to move.
Spacing pressing plate 31 can be the strip pressing plate arranged along two siding tracks, and is bolted on track 11, better ensure that smooth and easy degree, stability and the reliability of slide plate 3 in whole sliding process.
The foregoing is only the preferred embodiments of the present invention, be not limited to the present invention, for a person skilled in the art, the present invention can have various modifications and variations.Within the spirit and principles in the present invention all, any amendment done, equivalent replacement, improvement etc., all should be included within protection scope of the present invention.
