Description
Technical field
The invention belongs to mechanical structures and mechano-electronic field.
Background technique
Currently, there are two types of forms for the subrack structure of standard cabinet: 1. subracks are fixed on interior of equipment cabinet, the only preceding slotting mould of subrack
Block, preceding slotting module can be plugged on corresponding preceding slot position of the cabinet front from subrack, since preceding slotting module volume is larger, be accounted for
Slot position space is also larger, the limited amount of preceding slotting module in limited subrack space；2. subrack can slave by shaft
Cabinet internal rotating goes out cabinet, and multiple subracks can be composed in series rotating cage structure, and rotating cage slotting module, afterwards slotting module before having simultaneously are turning
After cage rotates out of cabinet around the shaft, the rear slotting region of rotating cage is exposed, preceding slotting module, afterwards slotting module can insert before rotating cage respectively,
It is plugged on slot position afterwards, although rotating cage structure increases the quantity of subrack module, but since pivot structure occupies a part
Cabinet wider width is caused in the space of cabinet width direction.
With the miniaturization of standard cabinet, only before slotting module subrack structure since module number increases it is limited without
Method is applicable in, and the rotating cage structure of traditional subrack can not be also applicable in due to the space limitation of miniature electric cabinet width direction.Small
Under space limitation in type electronics rack width direction, for the quantity for increasing subrack module as far as possible, there is still a need for same for subrack structure
When retain it is preceding insert and rear inserting structure, and the rear slotting module for being fully located at interior of equipment cabinet how to facilitate, reliably from subrack taking-up,
Replacement, time dress are problems to be solved.
Summary of the invention
In order to adapt to the space limitation of miniature electric cabinet in the direction of the width, meet subrack and meanwhile insert before having module, after
The needs of module are inserted, and guarantee operation that the preceding slotting module of subrack in miniature electric cabinet, rear slotting module are plugged from subrack just
Benefit and reliability, the present invention provide a kind of electronics rack subrack rotation positioning device, which can not only
The space limitation of miniature electric cabinet in the direction of the width is enough adapted to, and subrack structure has preceding slotting module simultaneously, inserts module afterwards,
And easily the rear slotting module of subrack can be taken out from subrack, replaced, return dress.
The technical solution adopted by the present invention to solve the technical problems is: being arranged immediately below the subrack of miniature electric cabinet
Bracket, bracket are connect by steel guide rail with cabinet, and bracket can be extracted out from cabinet front, and there are annular groove, bracket in bracket upper surface
Limited block is installed in top, and buffer stopper is fixed on limited block, axle sleeve is installed below bracket, ball locator is installed in axle sleeve side；It inserts
Bottom portion is connect with supporting plate, and locating piece, dagger, the axis with axial V-shaped groove, axis and bracket below supporting plate are installed below supporting plate
The axle sleeve of lower section cooperatively forms revolute pair, and the dagger below supporting plate is contacted with the annular groove of bracket upper surface, play support supporting plate,
The effect of subrack, supporting plate, subrack can be relative to carriage turns.
It is when inserting module after needing replacing, subrack, supporting plate, axis, axle sleeve, bracket is whole from cabinet front by steel guide rail
Extraction, then subrack, supporting plate, axis are rotated counterclockwise relative to bracket, axle sleeve, when rotating 60 °, locating piece and bracket below supporting plate
The buffer stopper of uppermost limit block contacts, and plays position-limiting action, the ball of ball locator enters the V-arrangement of square shaft under supporting plate below bracket
It in slot, plays the role of positioning, while the rear slotting module of subrack is exposed, and can easily be taken out, replace to rear slotting module, returning dress
Operation；After inserting module replacing after the completion, subrack, supporting plate, axis are rotated clockwise 60 ° relative to bracket, axle sleeve, determined below supporting plate
Position block is contacted with the buffer stopper of bracket uppermost limit block, and the ball of ball locator enters in the V-shaped groove of supporting plate lower axle under bracket,
After subrack is positioned, then subrack, supporting plate, axis, axle sleeve, bracket are integrally pushed into interior of equipment cabinet by steel guide rail and complete to fasten.
The present invention can be in the limited width spaces of miniature electric cabinet, easily by the rear slotting module of subrack from subrack
Middle to take out, replacement, return dress, operating process is easy, reliable.
Present invention will be further explained below with reference to the attached drawings and examples.
