[0024] Reference example Figures 1 to 4 An active filter cabinet with a rear cabinet door structure comprises a cabinet body 1, a rear cabinet door 2 and a first cabinet door 3 hinged to the cabinet body 1, the rear cabinet door 2 is provided with a concave cavity 21, through holes 22 are provided on both sides of the concave cavity 21, the first cabinet door 3 is hinged to the through holes 22, the first cabinet door 3 is provided with a first gear 4, the concave cavity 21 is provided with a driving device 5, and the first gear 4 is engaged, so as to make the first cabinet door 3 flip and fold with the through hole 22 as the axis;
[0025] It is worth mentioning that a PLC controller 11 is provided in the cabinet 1, and the PLC controller 11 controls the logic control, sequence control, and motion control of the flipping and folding of the first cabinet door 3;
[0026] It is worth mentioning that the first cabinet door 3 is provided with a movable lock core 31, and a start switch 32 is provided at the reset position of the lock core 31, and is electrically connected to the PLC controller 11, for turning and folding the first cabinet door 3. The first cabinet door 3 is provided with a reset button 6, and is electrically connected to the PLC controller 11, for resetting the first cabinet door 3. The reset of the lock core 31 triggers the start switch 32, and then the normally open programming instruction of the PLC controller 11 is closed, so that the motor 51 is powered, and the reset button 6 resets the first cabinet door 3;
[0027] It is worth mentioning that the concave cavity 21 is provided with a notch 23, and the concave cavity 21 is provided with a first limit switch 24 and a second limit switch 25, and is electrically connected to the PLC controller 11, and is used to limit the reset angle and the flip angle of the first cabinet door 3, and the notch 23 provides support for the support block 33, and the first limit switch 24 and the second limit switch 25 are used in conjunction with the first trigger block 35 and the second trigger block 36;
[0028] It is worth mentioning that the first cabinet door 3 is provided with a support block 33 and is arranged in the notch 23. Rods 34 are provided at both ends of the support block 33 and pass through the through hole 22. The rod 34 is provided with a first trigger block 35 and a second trigger block 36 for triggering the first limit switch 24 and the second limit switch 25 respectively. The first gear 4 is connected and fixed to the rod 34. When the support block 33 abuts against the notch 23, the first cabinet door 3 is flush with the cabinet door, and the rod 34 rotates with the through hole 22 as the axis. The first limit switch 24 and the second limit switch 25 are initially in a normally closed state. When the first cabinet door 3 is reset, the first trigger block 35 triggers the first limit switch 24, so that the first limit switch 24 is in a normally open state, and the power supply of the reversing motor 51 is cut off, and the circuit of the forward rotation of the motor 51 is turned on. The second trigger block 36 triggers the second limit switch 25, so that the second limit switch 25 is in a normally open state, and the power supply of the forward rotation motor 51 is cut off, and the circuit of the reverse rotation of the motor 51 is turned on.
[0029] It is worth mentioning that the driving device 5 includes a motor 51 and a second gear 52. The second gear 52 is fixedly connected to the shaft of the motor 51 and meshes with the first gear 4. The motor 51 is electrically connected to the PLC controller 11. The PLC controller 11 sends instructions to the motor 51 to rotate the shaft of the motor 51.
[0030] The use principle of the utility model is now described as follows:
[0031] When the first cabinet door 3 is unlocked from the cabinet body 1, the lock cylinder 31 is reset and triggers the start switch 32 to put it in a closed state. The current passes through the start switch 32 and the second limit switch 25, and provides a forward current for the motor 51. The motor 51 rotates and drives the second gear 52 to mesh with the first gear 4 to rotate, thereby causing the first cabinet door 3 to fold and rotate around the through hole 22 as the axis. At the same time, the first trigger block 35 leaves the first limit switch 24. When the second trigger block 36 triggers the second limit switch 25, the forward circuit of the motor 51 is cut off and the motor 51 stops running. At this time, the overall volume of the rear cabinet door 2 is reduced, thereby achieving the purpose of reducing the occupied space.
[0032] When the inspection is completed, the rear cabinet door 2 is reset first, and then the reset button 6 is pressed to close and conduct. The current passes through the reset button 6 and the first limit switch 24, providing reverse current for the motor 51. The motor 51 rotates and drives the second gear 52 to engage the first gear 4 to rotate, so that the first cabinet door 3 is flipped and reset, and the lock cylinder 31 is locked, preparing for the next triggering of the start switch 32.
[0033] The above design scheme can enable the product to achieve the advantages of small space occupation and easy opening.
