Abstract

The utility model discloses a power-supply control box for preventing a switch from being closed, which comprises a panel (1) which is arranged in the box, wherein the panel (1) is provided with a main loop switch (2), a car switch (3), a power switch of an air conditioner (4), a lighting switch of a well channel (5), and a socket (6). The utility model is characterized in that the panel (1) is also provided with a bracket (7) and a control lock (8) which is arranged on the bracket (7); the control lock (8) comprises a lock body (81) and a rotary pressure bar (82), and the lock body (81) is fixedly arranged on the bracket (7). The power-supply control box for preventing a switch from being closed has the advantages of convenient operation and high safety.

Description

Can prevent the power controling box of switch closure

Technical field

The utility model relates to a kind of power control unit, relates to a kind of power control unit that prevents switch closure with key specifically.

Background technology

Existing various types of diverter switch generally comprises body, lid, stirs handle and is arranged on intrinsic binding post, stirs contact open locking mechanisms such as spring.At present, most of elevator power controling boxs are installed in the public arena, as places such as dwelling house corridors, turn on and off power supply to be convenient to people by diverter switch, so anyone at any time can arbitrarily be switched on or switched off power supply.Yet, lift facility and elevator power controling box usually are not together, usually when equipment such as maintenance elevator, need cut off the electricity supply, for preventing to be caused danger by other people energized, need send someone to wait for by the elevator power controling box, or adopt other means to prevent other people energized, and do both wastes of manpower like this, also inconvenient.

Summary of the invention

Can be in order to overcome existing elevator power controling box by the problem of other people random energized, above-mentioned technical problem to be solved in the utility model provides a kind of power controling box that can prevent switch closure, it is when cutting off the electricity supply, and the key that has only use to match with it just can connect power supply.

The technical scheme in the invention for solving the technical problem is: the above-mentioned power controling box of switch closure that can prevent comprises the panel that is contained in the case, major loop switch, car switch, air-conditioning mains switch, well lighting switch, socket are housed on the panel, difference is, support and the control lock that is contained on the support also are housed on the above-mentioned panel, control lock comprises the lock body and is contained in the rotatable depression bar of lock body one end, and what rotatable depression bar one end was configured in above-mentioned major loop switch stirs handle top (depression bar being rotated by inserting key).

Above-mentioned lock body and rotatable depression bar are connected as a single entity and are the T shape.

It is as follows that the power controling box that can prevent switch closure of the present utility model has advantage compared with prior art:

This power controling box adopts the standard machinery lock and stirs the bat-handle switch combination, conveniently, realized when powered-down control cabinet power supply not by the function of other people energized simply, and it is simple in structure, low cost of manufacture, this power controling box is suitable for the public arena, promotes the use of as places such as dwelling house corridors.

Description of drawings

Fig. 2 is the Facad structure schematic diagram after the rotatable depression bar of the utility model power controling box that can prevent switch closure is opened;

Fig. 3 is the electrical schematic diagram that the utility model can prevent the power controling box of switch closure.

Embodiment

Below in conjunction with drawings and Examples the power controling box of switch closure that can prevent of the present utility model is described further.

As Fig. 1, shown in Figure 2, the above-mentioned power controling box of switch closure that can prevent comprises the panel 1 that is contained in the case, major loop switch 2 is housed on the panel 1, car switch 3, air-conditioning mains switch 4, well lighting switch 5, socket 6, difference is, above-mentioned panel 1 also is equipped with support 7 and the control lock 8 that is contained on the support 7, control lock 8 comprises lock body 81 and is contained in the rotatable depression bar 82 of lock body one end, lock body 81 is packed on the support 7, what rotatable depression bar 82 1 ends were configured in above-mentioned major loop switch 2 stirs handle 21 tops (depression bar being rotated by inserting key), and above-mentioned lock body (81) is connected as a single entity with rotatable depression bar (82) and is the T shape.

As shown in Figure 3, A, B, C three phase mains are connected with major loop switch 2 input terminals, B electricity mutually is connected with socket 6 binding posts with well lighting switch 5 respectively with zero line N, and C electricity mutually is connected with air-conditioning mains switch 4 binding posts with cage illumination 3 switches respectively with zero line N

When needs are closed the above-mentioned power controling box power supply that can prevent switch closure, promptly the three phase mains of major loop switch 2 to be disconnected, stir handle 21, turn off three phase mains, with key turns control lock 8, what make that rotatable depression bar 82 goes to major loop switch 2 stirs handle 21 tops, makes the handle 21 of stirring of buttoned-up major loop switch 2 can not be toward clawback (state as shown in Figure 1); When needs will close (disconnection) major loop switch 2 when reclosing three phase mains, must use key turns control lock 8 again, rotatable depression bar 82 is rotated, leave the top of stirring handle 21 (state as shown in Figure 2) of major loop switch 2, major loop switch 2 could be stirred handle 21 toward clawback, major loop switch 2 recloses three phase mains, to main circuit power supply.

Claims

1, a kind of power controling box that can prevent switch closure, comprise the panel (1) that is contained in the case, major loop switch (2), car switch (3), air-conditioning mains switch (4), well lighting switch (5), socket (6) are housed on the panel (1), it is characterized in that: above-mentioned panel (1) also is equipped with support (7) and is contained in control lock (8) on the support (7), control lock (8) comprises lock body (81) and rotatable depression bar (82), lock body (81) is packed on the support (7), and rotatable depression bar (82) one ends are configured in stirring above the handle (21) of above-mentioned major loop switch (2).

2, the power controling box that can prevent switch closure according to claim 1 is characterized in that: above-mentioned lock body (81) is connected as a single entity with rotatable depression bar (82) and is the T shape.
