Detailed Description
Referring to fig. 1, the single-hole lock-up prevention type power distribution cabinet provided by the invention, a double-key mechanical lock configured on a cabinet body comprises: base 1, first dabber 2, second dabber 3, first spring bolt 4, second spring bolt 5, cardboard 6 and spring 7.
The first mandrel 2 is rotatably and linearly slidably mounted on the base 1, and the first lock tongue 4 is mounted on the first mandrel 2 and moves synchronously with the first mandrel 2. The second mandrel 3 is rotatably mounted on the base 1, and the second lock tongue 5 is mounted on the second mandrel 3 and rotates synchronously with the second mandrel 3.
The first mandrel 2 is provided with a first position and a second position on a linear sliding track, and in the first position state, a lock hole matched with the first lock tongue 4 for locking a door is positioned on a rotating track of the first lock tongue 4. In the second position state, the lock hole is positioned at the periphery of the rotation track of the first lock tongue 4. That is, in the present embodiment, the mechanical lock can realize a normal lock control function by the rotation of the first lock tongue 4 only when the first spindle 2 is in the first position state; when the first spindle 2 is in the second position state, the mechanical lock is always in the unlocking state during the rotation of the first spindle 2.
The clamping plate 6 is slidably mounted on the base 1, and the first mandrel 2 is rotatably connected with the clamping plate 6. Therefore, the first mandrel 2 can also rotate relative to the clamping plate 6 while linearly sliding along with the clamping plate 6, so that the first mandrel 2 is driven to switch positions by the movement of the clamping plate 6. One end of the spring 7 is fixedly arranged on the base 1, and the other end is connected with the clamping plate 6. The spring 7 is located on the side of the card 6 remote from the first spindle 2.
The second lock tongue 5 is provided with a first state and a second state along with the rotation process of the second mandrel 3, and in the first state, the second lock tongue 5 abuts against the clamping plate 6 and pushes the first mandrel 2 to be switched to the first position through the clamping plate 6. In the first state, the spring 7 is in an extended state. In the second state, the second lock tongue 5 is far away from the clamping plate 6, and the clamping plate 6 drives the first mandrel 2 to switch to the second position along with the shrinkage of the spring 7. Specifically, the second lock tongue 5 is a cam structure coaxially arranged with the second spindle 3.
Thus, in this embodiment, when the first lock tongue 4 is in the first state, the first spindle 2 is in the first position, and the mechanical lock works normally along with the rotation of the first spindle 2; when the first locking bolt 4 is in the second state, the first spindle 2 is pulled to the second position by the spring 7. Therefore, when the mechanical lock is locked, besides unlocking through rotation of the first mandrel 2, unlocking can be realized through rotation of the second mandrel 3, so that the first mandrel 2 drives the first lock tongue 4 to retract.
Therefore, after the mechanical lock is applied, under the condition that the first mandrel 2 fails, the second mandrel 3 can be turned by the spare key to unlock, so that the abnormal processing risk of the power distribution cabinet caused by the door opening failure of the power distribution cabinet can be avoided. In this embodiment, through carrying out two key alternative control unblocks to the switch board, guaranteed the nimble reliability of switch board door control, be favorable to guaranteeing the reliability of switch board internal operation, maintenance, change etc..
In this embodiment, a clamping structure is disposed between the first mandrel 2 and the clamping plate 6, and the clamping structure is composed of a groove 8 coaxially disposed on the first mandrel 2 and a clamping block 9 protruding from the surface of the clamping plate 6 and inserted into the groove 8. Specifically, the cross section of the groove 8 and the clamping block 9 are of T-shaped structures. Therefore, the arrangement of the clamping structure ensures that the first mandrel 2 and the clamping plate 6 are relatively static and reliable in the linear direction while relatively rotating.
In this embodiment, cardboard 6 is the arc, and cardboard 6 inner circumference radius equals with first dabber 2 radius to further guarantee that cardboard 6 and first dabber 2 rotate the reliability of being connected, make things convenient for second spring bolt 5 to promote cardboard 6 at the rotation in-process simultaneously and rotate. The arc-shaped clamping plate 6 structure can reduce the area of the clamping plate 6 while avoiding the clamping plate 6 from blocking the second lock tongue 5 to be active, so that the whole mechanical lock is more compact.
In this embodiment, the top surface of the first mandrel 2 provided with the keyhole is located on the same plane as the top surface of the second mandrel 3 provided with the keyhole. Therefore, the mechanical lock is convenient to install, and the first mandrel or the second mandrel is convenient to rotate by controlling the key.
In this embodiment, the base 1 is provided with a guide groove 10, and the first mandrel 2 is mounted in the guide groove 10 in a linear motion and in a rotation manner. The arrangement of the guide groove 10 is beneficial to improving the reliability of the linear motion of the first mandrel 2. The catch plate 6 is mounted on the base 1 across the guide slot 10 to reduce friction, improve the flexibility of operation of the mechanical lock and reduce wear.
The single hole locking prevention formula switch board that this embodiment provided still includes the casing, and base 1, first dabber 2, second dabber 3, second spring bolt 5, cardboard 6 and spring 7 are all installed in the casing, and first spring bolt 4 stretches out the casing. Therefore, the mechanical lock is integrated through the shell, so that internal parts can be protected, and the mechanical lock is convenient to install.
In this embodiment, the first lock tongue 4 is used to control unlocking and locking of the lock. When the key is inserted into the first mandrel 2 and the first mandrel 2 is rotated, the first lock tongue 4 can be driven to rotate.
The foregoing is only a preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art should be able to apply equivalents and modifications to the technical solution and the inventive concept thereof within the scope of the present invention.
