[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0021] See also Figures 1 to 4In the utility model, a fast-switching emergency power supply includes a cabinet 1, a controller 2 is installed inside the cabinet 1, a power switch 3 is installed on the front of the controller 2, a phase switch 4 is fixedly connected to the right side of the power switch 3, a wiring terminal 5 is connected to the bottom of the power switch 3, two parallel vertical adjustment members 6 are installed inside the cabinet 1, a horizontal rail 7 is installed between the two vertical adjustment members 6, a movable wire harness block 8 is slidably installed on the horizontal rail 7, and a wire harness groove 13 arranged at equal distances is opened on the front of the movable wire harness block 8, an emergency power supply 14 is fixedly installed inside the cabinet 1, and the emergency power supply 14 is located below the controller 2 and is connected to the power switch 3 line.

[0022] In the utility model, the cabinet 1 is used as the main body of the device. When in use, it is first connected to the external conventional power supply line through the power switch 3. When in normal use, the controller 2 controls the power switch 3 to connect the conventional line for power supply. When a power outage or a conventional line failure occurs, the controller 2 controls the power switch 3 to switch the emergency power supply 14 as the emergency power supply for emergency power supply. When connecting to the outside, the wire harness is passed through the wire harness groove 13 on the movable wire harness block 8 in sequence to realize the positioning of the wire harness, and then connected to the wiring terminal 5 to realize wiring, and the height and horizontal position are adjusted by the vertical adjustment member 6 in cooperation with the movable wire harness block 8. To balance the downward pulling force of the wiring harness and make the wiring harness more stable, and the controller 2 can be used to adjust the phase switch 4 to switch the current phase, so as to adapt to the use scenarios of more types of electrical appliances, thereby realizing the advantages of good wiring effect of the wiring harness, high stability, and convenient later troubleshooting and maintenance. It solves the problem of the existing technology that the internal wiring is generally fixed by cable ties to bind and position the wiring harness. Since there are many wiring harnesses, it is very inconvenient for later inspection and troubleshooting after the cable ties are tied. At the same time, more wiring harnesses generate greater external force on the terminal position, which can easily cause unstable wiring for a long time.

[0023] See also Figure 2 , wherein: the vertical adjustment member 6 includes a vertical screw rod 61 and an adjustment ring 62, both ends of the vertical screw rod 61 are rotatably connected to the interior of the cabinet 1, the interior of the adjustment ring 62 is fixedly connected to the outside of the vertical screw rod 61, one end of the vertical screw rod 61 passes through the horizontal rail 7 and is threadedly connected thereto, and both ends of the horizontal rail 7 are slidably connected to the interior of the cabinet 1.

[0024] In the utility model, the vertical screw 61 is driven to rotate by adjusting the environmental protection 62 to drive the vertical height adjustment of the horizontal rail 7, so as to realize the height of the movable harness block 8, realize the adjustment of the tension of the harness connection point, and ensure the stability of the connection.

[0025] See also Figure 1 and Figure 4, wherein: a connecting ear block 81 is fixedly connected to the bottom of the movable harness block 8, the back of the connecting ear block 81 is in sliding contact with the cross rail 7, and corresponding threaded holes 9 are provided on the connecting ear block 81 and the front of the cross rail 7.

[0026] In the utility model, the movable harness block 8 is positioned by connecting the ear block 81 and cooperating with the threaded hole 9, so that the wiring stability is better.

[0027] See also Figure 3 , wherein: an arc-shaped end surface 131 is provided on the inner side of the cable harness groove 13 .

[0028] In the present invention, the arc-shaped end surface 131 makes the interior of the cable harness groove 13 more compatible with the shape of the cable harness.

[0029] See also Figure 3 and Figure 4 , wherein: arc-shaped elastic sheets 132 are fixedly connected to both sides of the inside of the cable trough 13, and the arc-shaped elastic sheets 132 are rubber sheets.

[0030] In the present invention, the arc-shaped elastic sheet 132 allows the wire harness to be conveniently inserted into the interior of the harness groove 13 , and achieves a clamping and positioning effect.

[0031] See also Figure 1 , wherein: a cabinet door 10 is hinged on the front of the cabinet body 1, and a row of power indicator lights 11 and phase indicator lights 12 are installed on the cabinet door 10.

[0032] In the utility model, the cabinet body 1 can be conveniently opened through the cabinet door 10 and the working status of the device can be conveniently observed through the power indicator light 11 and the phase indicator light 12.

[0033] The reason for using a power supply vehicle access box in most cases is that the mains fails and the power supply vehicle is needed as a temporary power supply to provide power to users and reduce power outage time. Therefore, before the power supply vehicle is connected, the mains has been disconnected due to the fault. At this time, the operator does not know the phase sequence of the mains before the power outage, so there is a risk of phase sequence error. Even if the access box can display the phase sequence of the power supply of the currently connected power supply vehicle, the operator has no way to judge whether the current phase sequence of the power supply vehicle is consistent with the phase sequence of the mains before the fault, and the risk of phase sequence error cannot be eliminated.

[0034] The above is only a preferred specific implementation of the utility model; however, the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solution and improved ideas of the utility model within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model.
