[0027] The technical solution of the utility model is further described below in conjunction with the accompanying drawings and specific embodiments.

[0028] Example

[0029] like Figure 2-3 and Figure 5As shown, a lockable power distribution cabinet proposed by the utility model comprises a cabinet body 1, a cabinet door 101 rotatably mounted on the cabinet body 1, and also comprises: an automatic power-off mechanism installed in the cabinet body 1, and the automatic power-off mechanism automatically powers off the circuit in the cabinet body 1 when the cabinet door 101 is opened. The automatic power-off mechanism comprises a fixed block 2 fixedly mounted on the cabinet body 1, a driving column 201 slidably mounted on the fixed block 2, a handle 202 fixedly mounted on the driving column 201, a first spring 203 fixedly mounted on the driving column 201 and fixedly connected to the fixed block 2, a first terminal 204 fixedly mounted on one end of the driving column 201, a first conductive sheet 205 fixedly mounted on the first terminal 204, a second terminal 206 slidably mounted on the cabinet body 1 and located at one side of the first terminal 204, a second conductive sheet 207 fixedly mounted on the second terminal 206, and a pressing block 4 fixedly mounted on the cabinet door 101 and located at one side of the driving column 201. The first terminal 204 is connected to an external power source, and the second terminal 206 is electrically connected to the electrical components inside the cabinet 1. When the cabinet door 101 is closed, the pressure block 4 will be mortgaged on the handle 202, which will drive the driving column 201 to move to the left. This process compresses the first spring 203, and the driving column 201 will drive the first terminal 204 to move in a direction close to the second terminal 206, so that the first conductive sheet 205 contacts the second conductive sheet 207, so that the circuit is connected. When the cabinet door is opened, under the action of the first spring 203, the driving column 201 will be driven to move in a direction away from the second terminal 206, so that the first conductive sheet 205 and the second conductive sheet 207 are separated, so that the circuit is automatically disconnected to prevent the inspection personnel from being electrocuted;

[0030] Among them, a first slide groove 7 is provided on the inner top plate of the cabinet 1, a connecting block 701 is slidably installed in the first slide groove 7, the second terminal 206 is fixedly connected to the connecting block 701, a second spring 702 is fixedly installed on the connecting block 701, and the other end of the second spring 702 is fixedly connected to the inner wall of the first slide groove 7. After the first conductive sheet 205 contacts the second conductive sheet 207, it will drive the second terminal 206 to continue to move to the left, and this process compresses the second spring 702, so that the second conductive sheet 207 is close to the first conductive sheet 205 through the second spring 702 to prevent poor contact caused by vibration.

[0031] like Figure 2-4As shown, it also includes: a power transmission detection component, which is installed on the automatic power off mechanism, and the power transmission detection component manually transmits power to the circuit in the cabinet 1 when the cabinet door 101 is opened. The power transmission detection component includes a limit plate 3 fixedly installed on the driving column 201, a support block 501 slidably installed on the cabinet 1, a connecting sleeve 502 fixedly installed on the support block 501, a limit groove 503 provided in the connecting sleeve 502, a rotating shaft 506 rotatably installed on the connecting sleeve 502, a baffle 507 fixedly installed on the rotating shaft 506, a limit bar 505 fixedly installed on the rotating shaft 506 and located in the limit groove 503, and a torsion spring 508 fixedly installed on the connecting sleeve 502 and fixedly connected to the rotating shaft 506. The limit groove 503 is in a semicircular arc shape, and the limit groove 503 allows the rotating shaft 506 to rotate only 180 degrees. When it is necessary to energize the circuit for testing, the handle 202 is manually pushed, so that the driving column 201 drives the first terminal 204 to move toward the second terminal 206, so that the first conductive sheet 205 contacts the second conductive sheet 207 to complete the circuit connection. This process will drive the limit plate 3 to contact the baffle 507 and squeeze the baffle 507, so that the baffle 507 drives the rotating shaft 506 to rotate. When the limit plate 3 moves to the left side of the baffle 507, the torsion spring 5 08, the shaft 506 is driven to reverse, thereby driving the baffle 507 to reset. When the baffle 507 moves to the vertical position, the limit groove 503 limits the shaft 506, so that the shaft 506 cannot continue to rotate, thereby keeping the baffle 507 in a vertical state. The baffle 507 will limit the limit plate 3 to prevent the driving column 201 from driving the first conductive sheet 205 and the second conductive sheet 207 to separate under the action of the first spring 203, so that circuit detection can be performed.

[0032] Among them, a second slide groove 5 is provided in the cabinet 1, and the support block 501 is slidably connected to the second slide groove 5. A third spring 504 is fixedly installed on the support block 501, and the other end of the third spring 504 is fixedly connected to the inner wall of the second slide groove 5.

[0033] like Figure 2-3As shown, it also includes: a door closing reset mechanism, which is connected to the power transmission detection component, and the door closing reset mechanism resets the power transmission detection component when the cabinet door 101 is closed. The door closing reset mechanism includes a drive plate 6 fixedly mounted on the connecting sleeve 502, a connecting strip 601 fixedly mounted on the cabinet door 101, and a roller 602 rotatably mounted on the connecting strip 601, and the roller 602 abuts against the drive plate 6. The drive plate 6 is triangular, and the roller 602 abuts against the hypotenuse of the drive plate 6. When the cabinet door 101 is closed, the connecting strip 601 will be driven to move, thereby driving the roller 602 to abut against the driving plate 6, so that the driving plate 6 drives the supporting block 501 to move downward along the second slide groove 5, thereby driving the baffle 507 to move downward. When the baffle 507 moves down to a position where it does not contact the limit plate 3, the baffle 507 will no longer limit the limit plate 3, and under the action of the pressing block 4, the first conductive sheet 205 contacts the second conductive sheet 207, thereby connecting the circuit. When the cabinet door 101 is opened again, the limit plate 3 will first move to the right side of the baffle 507 under the action of the first spring 203.

[0034] like Figure 1 As shown, an indicator light 104 and a warning sign 102 are fixedly mounted on the cabinet door 101, as well as a door lock 103 for opening and closing the cabinet door 101. The cabinet door 101 can be opened by opening the door lock 103, and the cabinet door 101 can be prevented from being opened by non-operating personnel by closing the door lock 103.

[0035] Working principle: The first terminal 204 is connected to the external power supply, and the second terminal 206 is electrically connected to the electrical components inside the cabinet 1. When the cabinet door 101 is closed, the pressing block 4 will drive the driving column 201 to move to the left, and drive the first terminal 204 to move in the direction close to the second terminal 206, so that the first conductive sheet 205 is in contact with the second conductive sheet 207, so that the circuit is connected. When the cabinet door is opened, under the action of the first spring 203, the driving column 201 will be driven to move away from the second terminal 206, so that the first conductive sheet 205 is separated from the second conductive sheet 207, so that the circuit is automatically disconnected to prevent the inspector from electric shock.

[0036] When it is necessary to energize the circuit for testing, the handle 202 is manually pushed to make the first conductive sheet 205 contact the second conductive sheet 207 to complete the circuit connection. This process will drive the limit plate 3 to contact and squeeze the baffle 507, so that the baffle 507 drives the rotating shaft 506 to rotate. When the limit plate 3 moves to the left side of the baffle 507, the rotating shaft 506 is driven to reverse under the action of the torsion spring 508. After the baffle 507 moves to the vertical position, the limit groove 503 limits the rotating shaft 506, so that the rotating shaft 506 cannot continue to rotate, so that the baffle 507 remains in the vertical state. The baffle 507 will limit the limit plate 3 to prevent the driving column 201 from driving the first conductive sheet 205 and the second conductive sheet 207 to separate under the action of the first spring 203, so that the circuit can be tested.

[0037] When closing the cabinet door 101, the roller 602 is driven to abut against the driving plate 6, so that the driving plate 6 drives the support block 501 to move downward along the second slide groove 5, thereby driving the baffle 507 to move downward. When the baffle 507 moves down to a position where it does not contact the limit plate 3, the baffle 507 will no longer limit the limit plate 3. When the cabinet door 101 is opened again, the limit plate 3 will first move to the right side of the baffle 507 under the action of the first spring 203.
