Embodiment
As Figure 1-4, the ring main unit includes cabinet 1 to the present invention, and the front end of the cabinet 1 is provided with least one operation
Panel 2, it is characterised in that the component that blocks includes roller shutter 3, and the front end that the roller shutter 3 is located at cabinet 1 by fixed support is pushed up
Portion, the roller shutter 3 include spool 31 and cord 32, the cord 32 be provided with it is at least one it is openable turn over curtain 320, it is described to turn over
Curtain 320 corresponds the guidance panel 2.
Also include positioning component 4, the positioning component 4 includes locating ring 41 and lock 42, and the locating ring 41 is fixed on
The bottom of cabinet 1, the lock 42 are fixed on the bottom of roller shutter 3, the locating ring 41 and the adaptation of lock 42.So, locating ring and lock
Button is reliably connected, soft roller shutter connected at both caused by be stably bonded cabinet under convergent force effect, will not by wind-force or
Other extraneous factors influence and depart from cabinet, it is ensured that the security of operating process.
The present invention the first embodiment be:The roller shutter 3 or cabinet 1 are provided with some magnets 5.Magnet and volume
The connected mode of curtain can be gluing or needlework suture, so, can by roller shutter in the presence of magnet magnetic field force
By being fixed on cabinet.
The guidance panel 2 is provided with button 20.Be equipped with the guidance panel of diverse location different operation buttons or
Disconnecting link, to adapt to different operational requirements.
The curtain 320 that turns over is exactly that annular tear is offered on cord 32, part cord corresponding to annular tear.So,
In practical operation, raise and turn over curtain, exposing corresponding guidance panel can be operated, and VELCRO can be passed through by turning over after curtain starts
Or magnet is fixed on cabinet, so that it may so that guidance panel appears all the time, convenient operation.
Also include plastics stripe board 6, the plastics stripe board 6, which is movably connected on the upper end of cord 32, (can use watering to bond, side
Convenient to operate).At work, magnet can be used to adsorb plastics stripe board on cabinet, so, staff is in operation interval
When can grip plastics stripe board and take a quick nap, meanwhile, instrument, screw etc. can be also placed in plastics stripe board, reduce and seek
The time of instrument is looked for, improves operating efficiency.
Operation handle 7 is additionally provided with, operation handle is located on spool, and the type of drive of operation handle 7 is manual actuation or electricity
Machine drives.It is simple in construction using manual actuation, it is swift to operate using motorized motions, can flexibly it be selected with demand according to varying environment
Select.
The curtain that turns over is provided with mark, is easy to fast searching to corresponding guidance panel to be operated.
The present invention second of embodiment be:Also include flexible support bar 8, the cord and turn over curtain and be provided with the surface
Some to wear button 9, the flexible support bar is detachably located at some wear in button.Set it is some wear button, be easy to place flexible support bar,
Enable the state that curtain keeps digging of turning over, so, when rainy, curtain is turned in unlatching, plays the effect of keeping off the rain, avoids rainwater from entering cabinet
In vivo, security is improved.The tip-up state for turning over curtain is applied to less operating space, especially in the presence of a harsh environment, improves operation
Convenience.
The flexible support bar includes some support bodies 80, and adjacent support body is articulated and connected, and convenient processing, operation is reliable, cost
It is low.
The cabinet is provided with hook 10, described to link up with for placing flexible support bar, convenient to place.
