Description
Technical field
The utility model relates to the outer power-off protection apparatus of a kind of case, particularly a kind of mine power resource case uncovering power-off locking protector.
Background technology
Power supply case is as to the antiknock device of down-hole broadcast terminal, broadcast extension set offer direct supply, needing monthly regularly uncap checks inner circuit and the intact situation of explosion-proof performance, as run into work fault, in addition it is also necessary to have a power failure at any time, uncaps and carries out maintenance operation. But the structure of existing power supply case is made up of housing, case lid, hold-down nut formula cable entry etc., hinge engaging structure is adopted between front case lid and end body, power supply case is a cavity only, cavity is directly entered with the cable of each equipment connection, being connected on corresponding position, exchange inlet wire is directly connected in terminal block. As long as under the normal power supply state of the upper level power supply powered for power supply case, even if after power supply case uncaps, being still charged working order. So, if maintenance personnel are not in strict accordance with working specification operation, when not cutting off higher level's AC power, maintenance of just uncapping, very easily causes electric shock, even causes more serious gas, coal dust explosion accident.
Summary of the invention
The purpose of this utility model is to overcome the deficiency of currently available products, it is provided that a kind of structure design simple mine power resource case uncovering power-off locking protector.
The technical scheme in the invention for solving the above technical problem is: this power supply case uncovering power-off locking protector; comprise transfer lever and magnetic switch; the through hole of the rotating shaft of described transfer lever on power supply case lid is bearing on case lid; one end that case lid is stretched out in described rotating shaft is fixed with break-make conversion spanner, and break-make conversion spanner end winding support has shielding block. Described rotating shaft is stretched into power supply case lid one end and is fixed with machinery locking claw and plectrum support bar successively, and described plectrum support bar end winding support has switch triggering plectrum.Angle 5 °-175 ° between described machinery locking claw and plectrum support bar. Described magnetic switch is fixed on inside described case lid, and in switch triggering plectrum rotational travel range.
In closed state, break-make conversion spanner is in make-position to this power supply case uncovering power-off locking protector, and shielding block is positioned at a certain bolt foreign side of casing, covers bolt hole. Meanwhile, being positioned at casing switch triggering plectrum and block the magnetic switch being fixed on case lid, power supply case is charged, and the tongue-shaped projection portion that machinery locking claw is stuck in case lid framework is inboard, and case lid cannot be opened. When need to open case lid maintenance, screw break-make conversion spanner clockwise or counterclockwise to open site, and switch triggering plectrum does not block magnetic switch, power-off in power supply case, shielding block no longer covers bolt hole, bolt is disassembled, and machinery locking claw is no longer stuck in the inboard, tongue-shaped projection portion of case lid framework, and case lid can be opened. The following is the relevant technique means in some optimal technical scheme.
Conversion spanner outside described case lid and the mechanical locking claw inside case lid, the two is in same plane.
Described rotating shaft, plectrum support bar, machinery locking claw and break-make conversion spanner all adopt antirust anti-abrasive material manufacture.
Further, for reducing wear, it is provided with every cover between rotating shaft and case lid support holes.
The beneficial effects of the utility model are: structure is simple, with low cost, mine explosion-suppression and intrinsic safety power supply can be made to cut off the electricity supply before uncapping, if do not cut off the electricity supply cannot opening power case lid, ensure that safety.

Embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is described in further detail:
As Figure 1-4; this power supply case uncovering power-off locking protector comprises through rotating shaft 2 the through hole transfer lever being bearing on power supply case lid 1 and the magnetic switch 8 being fixed on inside case lid 1; the rotating shaft 2 of transfer lever is stretched out power supply case lid 1 one end and is fixed with break-make conversion spanner 4, and break-make conversion spanner 4 end winding support has shielding block 3. Rotating shaft 2 is stretched into power supply case lid 1 one end and is fixed with machinery locking claw 9 and plectrum support bar 11 successively, and plectrum support bar 11 end winding support has switch triggering plectrum 7. Between machinery locking claw 9 and plectrum support bar 11, included angle A MP.AMp.Amp is 5 °-175 °, is shown as 90 ° in Fig. 1,2. Magnetic switch 8 is fixed in switch triggering plectrum 7 rotational travel range.
Stretching out the conversion spanner 4 outside power supply case lid 1 and the mechanical locking claw 9 inside case lid 1, the two is in same plane.
For reducing wear, it is provided with between rotating shaft 2 and the corresponding support holes on case lid 1 every cover 6.
