The specific working schematic diagram of the switch cabinet door closing interlocking mechanism in the embodiment is as follows:
under the normal working and running state of the switch cabinet, the grounding switch is in an open state, the front door and the rear door are in a closed state, the lower door hook 71 limits the front door pin 74 fixed on the front door, and the front door cannot be opened; can make even latch fitting 82 to the direction motion of preceding door through a back door connecting plate 81 after the back door is closed, thereby drive and articulate back door hook 83 on even latch fitting 82 along setting up the back door hook axle clockwise rotation on even latch fitting 82, can just block in the card hole 811 of back door connecting plate 81 after rotating certain angle, and meanwhile, under the separating brake state, 3 card bayonet 21 positions of second limiting plate on 2 first limiting plate, block 2 first limiting plate, ensured under this state, 2 first limiting plate can not backward movement, thereby make back door hook 83 be in the state of colluding in back door connecting plate 81 always, the back door can't be opened, when having realized "earthing switch is in the separating brake state, can not open the cubical switchboard before, the function of back door".
The two ends of the third limiting shaft 4 are thin shafts, the middle part of the third limiting shaft is a thick shaft, and if the front door of the switch cabinet is in an open state, the thick shaft of the third limiting shaft 4 is clamped in the limiting hole 12 of the pressing plate 1 to prevent the pressing plate 1 from moving downwards; when the front door is closed, the third limit shaft 4 can move towards the inside of the cabinet along the axis direction, after the third limit shaft 4 moves for a certain distance, the thin shaft part of the third limit shaft 4 enters the limit hole 12, the downward limit effect on the pressing plate 1 cannot be achieved at the moment, the pressing plate 1 can be pressed down by a hand under the state, and therefore the grounding switch operation shaft can be further operated. The function that the grounding switch can be operated under the condition that the front door of the switch cabinet is closed is realized.
Similarly, if the back door is in an open state, the second elastic reset piece 6 is in a natural state, and the first limit plate 2 has a limit effect on the pressure plate 1; when the back door is in the closed condition, back door connecting plate 81 makes interlock spare 82 move to the front door direction, and then make first limiting plate 2 move to the front door direction through connecting axle 9, second elasticity resets 6 and is in by tensile state, at this moment, after first limiting plate 2 removed a locating position, the hole 23 of dodging of the turn-ups 22 of its top just corresponds with kink 13 positions on the clamp plate 1, at this moment, clamp plate 1 can pass and dodge hole 23 downstream, thereby can further operate earthing switch operating axis 10, realized "under the cubical switchboard back door closed condition, just can operate the function of earthing switch.
Namely, the switch cabinet door closing interlocking mechanism in the embodiment realizes the function of switching-on operation of the grounding switch only when the front and the rear of the switch cabinet are closed.
When the front door and the rear door of the switch cabinet are both in a closed state, the switch-on operation can be performed on the grounding switch: the pressing plate 1 is pressed downwards, and the first elastic resetting piece 5 is stretched to accumulate energy, so that the upper door hook 71 is driven by the pressing plate 1 to rotate anticlockwise and downwards around a rear shaft thereof, and a front door pin 74 is locked. Pressing plate 1 pushes down the back, can pass through operating handle and dodge the hole and insert operating handle and carry out the rotation operation to earthing switch operating axis 10, drives the connecting lever and carries out rotary motion, and the connecting lever supports and presses on second limiting plate 3, can apply pressure for second limiting plate 3 through contacting the cooperation with second limiting plate 3 when the connecting lever rotates and make its down motion, until keeping the position. When the second limit plate 3 moves, the force is applied to the lower door hook 72 inserted in the second limit plate 3, so that the lower door hook rotates anticlockwise and downwards around the rear hinge shaft 73, and the door locking function of the lower door hook 72 on the front door pin 74 is unlocked.
After the closing operation, the operating handle is pulled out, the pressure plate 1 can rebound upwards under the pulling force of the first elastic reset piece 5 due to no limit, the upper door hook 71 is driven by the pressure plate 1 to rotate upwards clockwise around a shaft behind the pressure plate, the door locking function of the upper door hook 71 on the front door pin 74 is unlocked, and at the moment, the front door can be opened; pressing plate 1 up moves, second limiting plate 3 down moves the back, no longer prevents the motion of first limiting plate 2 to the back door direction to first limiting plate 2 drives back door hook 72 anticlockwise rotation under the effect of the restoring force of second elasticity piece 6 that resets, and the unblock can be opened the limit function of back door connecting plate 81 to the back door. The function that the front door and the rear door of the switch cabinet can be opened only when the grounding switch is switched on and the operating handle is pulled out is realized.
The above examples are only intended to illustrate the technical solution of the present invention, but not to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that various changes may be made and equivalents may be substituted for elements thereof; and such modifications or substitutions do not depart from the spirit and scope of the corresponding technical solutions.
