DETAILED DESCRIPTION

[0025] The embodiments of the application will be further described below in conjunction with the drawings and examples. The following examples are used to illustrate the application, but cannot be used to limit the scope of the application.

[0026] As shown in the accompanying Figure 1 to the accompanying Figure 7 as shown:

[0027] Example 1: The application provides a mis-touch prevention live display distribution panel operating panel, which comprises a cabinet 1, a cabinet door 4, an interlocking mechanism and a prompting mechanism; the interlocking mechanism comprises a fixed frame 701 arranged at the other end of the cabinet door 4, a top rod 13 movably mounted in the fixed frame 701, a transmission spring 1301 movably mounted on the periphery of the top rod 13, a coil 7 arranged at the top of the fixed frame 701 on the periphery of the transmission spring 1301, a wiring device 9 fixedly connected to the other end of the cabinet door 4 on one side of the fixed frame 701, and the coil 7 connected to the wiring device 9; the interlocking mechanism further comprises a lock block 6 fixedly arranged on the inner side wall of the cabinet 1, a lock hole 601 arranged in the lock block 6, a support frame 1001 fixedly connected to the other end of the cabinet door 4 on one side of the lock block 6, a lock rod 10 movably mounted in the support frame 1001, a return spring 1003 arranged between the lock rod 10 and the support frame 1001, a fixed block 1002 fixedly connected to the outer side wall of the lock rod 10, and the fixed block 1002 and the rotating pusher 12 arranged in parallel, the rotating pusher 12 movably mounted at the other end of the cabinet door 4 at the bottom of the top rod 13, and the rotating pusher 12 and the cabinet door 4 arranged with a second torsion spring 1201.

[0028] First, the external electrical equipment is divided into four modules installed in the cabinet 1, four modules are powered, and the power supply line is connected to the connector 9. If the electrical equipment power supply is connected, the current will flow into the coil 7 through the connector 9, so that the coil 7 generates electromagnetic force, which attracts the top rod 13 and causes the transmission spring 1301 around the top rod 13 to shrink. The top rod 13 moves downward under the action of the electromagnetic force, and pushes the rotating pusher 12. Because the rotating pusher 12 and the fixed block 1002 on the lock rod 10 are parallelly arranged, the rotating rotating pusher 12 will drive the fixed block 1002 to move, thereby making the lock rod 10 move in the support frame 1001, and pulling the reset spring 1003, so that the lock rod 10 is inserted into the lock hole 601 of the lock block 6 on the inside wall of the cabinet 1, realizing the interlocking locking of the cabinet door 4 and the cabinet 1, and preventing the staff from opening the cabinet door 4 to cause misoperation when the equipment is powered on;

[0029] When the electrical equipment is powered off, the electromagnetic force of the coil 7 disappears, the transmission spring 1301 is no longer constrained by the electromagnetic force and rebounds to reset the top rod 13. The pushing force of the top rod 13 on the rotating pusher 12 is removed, the rotating pusher 12 reversely rotates and resets under the action of the second torsional spring 1201, the stress of the fixed block 1002 also disappears, the lock rod 10 exits from the lock hole 601 under the action of the elastic force of the reset spring 1003, the interlocking locking state is released, and the staff can normally open the cabinet door 4. This design can make the electrical equipment in any module of the cabinet 1 be powered on, and the cabinet door 4 is in a locked state, while not affecting the separate power supply.

[0030] Specifically, the bottom end of the fixed frame 701 is provided with a limiting hole 702, and the lock rod 10 is embedded in the limiting hole 702.

[0031] The lock rod 10 penetrates the limiting hole 702, and the lock rod 10 can move up and down in the limiting hole 702.

[0032] Specifically, the other end of the cabinet door 4 at the bottom of the support frame 1001 is fixedly connected with the wire holder 11.

[0033] The staff can place the cable connected with the electrical equipment in the inside of the wire holder 11, so that the wire holder 11 supports the cable, and it is more convenient for the staff to bundle the wire.

[0034] Embodiment two: the embodiment is basically the same as the previous embodiment, the difference is that the prompting mechanism includes a protective frame 2 fixedly arranged at one end of the cabinet door 4, the inside of the protective frame 2 is provided with a prompt lamp 5, the surface of the protective frame 2 at one end of the prompt lamp 5 is movably installed with an insulating plate 3, and the prompt lamp 5 and the coil 7 are provided with a wire 501.

[0035] Specifically, the prompting mechanism further comprises a fixing member 801 arranged on the top of the fixing frame 701, and a prompt marker 8 movably arranged on the inner side of the fixing member 801, and a first torsion spring 802 arranged between the prompt marker 8 and the fixing member 801.

[0036] When the power line of the external electrical equipment is connected to the connector 9, the prompt lamp 5 of the prompting mechanism is powered at the same time. When the electrical equipment is powered on, the current flows into the prompt lamp 5 through the wire 501, and the prompt lamp 5 turns on the red light. Since the prompt lamp 5 is located in the protective frame 2, and the surface of the protective frame 2 is provided with the insulating plate 3 which is transparent and made of insulating glass material, the prompt lamp 5 can be protected from external damage, and the red light can directly remind the staff that the equipment is in a live state, thereby playing a warning role.

[0037] When the electrical equipment is powered off, the power supply of the prompt lamp 5 is interrupted, and the red light is turned off. At the same time, with the disappearance of the electromagnetic force of the coil 7, the transmission spring 1301 rebounds, and in the rebounding process, the prompt marker 8 in the fixing member 801 on the top of the fixing frame 701 is pushed. The first torsion spring 802 is arranged between the prompt marker 8 and the fixing member 801. Under the joint action of the pushing force of the transmission spring 1301 and the elastic force of the first torsion spring 802, the prompt marker 8 rotates. The staff can observe the rotating state of the prompt marker 8 through the transparent plate 401 on the cabinet door 4, so as to further confirm that the electrical equipment has been powered off, without relying on the monitoring and cooperation of various sensors, thereby reducing the cost, improving the safety of operation through double prompting, and facilitating the quick confirmation of the unpowered module.

[0038] Working principle: The electrical equipment is installed in the cabinet body 1, and the power line thereof is connected to the connector 9 to supply power to the prompt lamp 5. When the electrical equipment is powered on, the current flows into the coil 7 through the connector 9, and the coil 7 generates electromagnetic force to attract the top rod 13, so that the transmission spring 1301 is contracted, the top rod 13 is lowered to push the rotating pusher 12 to rotate against the elastic force of the second torsion spring 1201, and then the fixed block 1002 drives the lock rod 10 to compress the reset spring 1003, and is inserted into the lock hole 601 of the lock block 6 along the limiting hole 702, thereby realizing the interlocking locking of the cabinet door 4 and the cabinet body 1. At the same time, the prompt lamp 5 is powered on through the wire 501 to turn on the red light, and the staff can observe the live state through the transparent insulating insulating plate 3. When the electrical equipment is powered off, the electromagnetic force of the coil 7 disappears, the transmission spring 1301 rebounds to reset the top rod 13, the rotating pusher 12 reversely rotates under the action of the second torsion spring 1201, the lock rod 10 exits the lock hole 601 under the elastic force of the reset spring 1003, and the locking is released. The prompt lamp 5 is powered off to turn off the red light, the transmission spring 1301 rebounds to push the prompt marker 8, and the prompt marker 8 rotates under the cooperation of the first torsion spring 802. The staff can observe the rotating state of the prompt marker 8 through the transparent plate 401 on the cabinet door 4 to confirm that the equipment is powered off.
