Description of drawings
Fig. 1 is structural representation of the present utility model.
Structural representation when Fig. 2 is powered-down chamber door of the present utility model.
Embodiment
In order to make realization technological means of the present utility model, creation characteristic, to reach purpose and effect is easy to understand, below in conjunction with concrete diagram, further set forth the utility model.
Shown in Fig. 1～2, temporary electricity power supply machinery positive locking device, comprise power supply box 1, power supply chamber door 2 and interlock, be provided with the master switch 10 with electric leakage, short-circuit protection function in the described power supply box 1, described power supply chamber door 2 is provided with rain cover 22, door lock 21 and chamber door keyhole 23, described rain cover 22 is provided with handle hole 221, and described interlock includes locking support 4, lower locking support 3, locking tongue 5, jam plate axle 6, locking connecting rod 8; Described upper locking support 4, lower locking support 3 all is fixed on the power supply box 1, described upper locking support 4 is positioned at master switch 10 upper ends, upper locking support 4 is provided with locking tongue axle sleeve 51, described lower locking support 3 is arranged on the shift bar body of master switch 10, lower locking support 3 is provided with operating handle 31, lower locking support 3 both sides also are provided with rotation axis 32, described locking tongue 5 one ends pass described locking tongue axle sleeve 51, locking tongue 5 other ends are fixed on the operating handle 31, described jam plate axle 6 one ends are fixed on the locking support 4, jam plate axle 6 other ends are provided with latch plate 7, the power supply box 1 of described latch plate 7 tops is provided with keyhole 9, described locking connecting rod 8 one ends are arranged on the latch plate 7, and locking connecting rod 8 other ends are arranged on the power supply chamber door 2.
The utility model in use, at first the powered-down chamber door 2, at this moment locking connecting rod 8 promotes latch plate 71 inboard rotation along latch shaft 6 to power supply box, described operating handle 31 passes described handle hole 221 and enters in the rain cover 22, chamber door keyhole 23 on the power supply chamber door 2 overlaps with the keyhole 9 on the power supply box 1, locks door lock 21, upwards pulls operating handle 31, locking tongue 5 passes chamber door keyhole 23 on the power supply chamber door 2 and the keyhole 9 on the power supply box 1, realizes the positive locking power down function.
During power supply box 1 normal operation of the present utility model, power supply chamber door 2 is closed, the user pulls downwards behind the operating handle 31 can opening power chamber door 2, after power supply chamber door 2 is opened, the binding post of pile crown is closed again on the master switch 10, inlet wire is low-voltage cable, so the user does not have the possibility of electric shock.After user's wiring is complete, after power supply chamber door 2 must being shut, can send electricity, otherwise master switch 10 can't close a floodgate.No matter user's wiring correctness has dual leakage switch, short switch protection on the one hand; Power supply box 1 adopts the metal cabinet closed protective on the other hand, and power supply box 1 ground connection is so can not damage human body.
