Description

Switch cabinet

Technical Field

The utility model relates to a switch cabinet.

Background

The switch cabinet can comprise a switch mechanism, wherein the switch mechanism is provided with a grounding operation hole and can be in a grounding switch-on state and a grounding switch-off state. The switchgear may also include a cable compartment door panel and a fuse canister door panel. If the switch mechanism is in a grounding opening state or the grounding operation hole is not locked, the cable chamber door plate and the fuse tube door plate are ensured to be in a closed state and cannot be opened; only when the switch mechanism is in the grounding opening state and the grounding operation hole is well locked, the cable chamber door panel and/or the fuse tube door panel can be allowed to be opened. Because, the switch cabinet needs to be provided with an interlocking structure that ensures interlocking between the cable compartment door panel and the fuse tube door panel and the ground operation hole to ensure safety. The existing interlocking structure relates to too many parts, is easy to jam, influences customer experience, and has poor compactness.

Therefore, there is a need for a switchgear cabinet that can ensure the above-described interlocking between the cable compartment door panel and the fuse tube door panel and the ground operation hole with a simple and compact interlocking structure.

As shown in fig. 1-2, according to an embodiment of the present invention, the proposed switchgear 1 comprises at least one door panel and a switching mechanism, which can switch between at least a ground-engaging and a ground-disengaging state, and the at least one door panel can switch between an open state and a closed state, and only when the switching mechanism is in the ground-engaging and a closed state, any one of the door panels of the switchgear can be switched from the closed state to the open state, and if the switching mechanism is in the ground-engaging and a disengaged state, then any door panel of the switchgear is not allowed to be opened, so as to ensure safety. In one particular embodiment, the switch mechanism may be a three-position mechanism.

As shown in fig. 1-2, 5 and 11, the switch mechanism is provided with at least a ground operating hole and a cover plate 110, the cover plate 110 being capable of switching between a covering position covering the ground operating hole and an opening position opening the ground operating hole, the ground operating hole being fully exposed only when the cover plate 100 is in the opening position and allowing, for example, a ground operating wrench to be inserted thereinto for a corresponding switching operation. More specifically, a return spring (not shown in the drawings) for urging the cover plate to return when the cover plate 100 is in the open position may be provided between the cover plate 110 and the main body of the switch mechanism. Furthermore, the switching mechanism comprises a cam 120, which cam 120 is rotatable between a non-stop position and a stop position upon switching of the switching mechanism between a ground closing state and a ground opening state. More specifically, when the switch mechanism is in the ground opening state, the cam 120 is in the stop position; when the switching mechanism is in the ground-on state, the cam 120 is in the non-stop position. And more specifically, any door panel of the switchgear cannot be opened when the cam 120 is in the stop position, but is only allowed to open when the cam 120 is in the non-stop position. Fig. 5 shows the cam 120 in the stop position, and fig. 2 and 11 show the cam 120 in the non-stop position.

That is, in such a switchgear 1, if the switching mechanism is in the ground-closed state, the door panel of the switchgear 1 may be opened. In order to ensure safety when any one of the door panels is in the open state, it is ensured that the switching mechanism does not switch from the ground-closed state to the ground-open state, which can be achieved by ensuring that the ground-operating hole is not opened, and more specifically, by ensuring that the cover panel 110 is held in the closed position.

To this end, as shown in fig. 2, 4-9 and 11, according to an embodiment of the present invention, the proposed switchgear cabinet 1 may comprise a common linkage assembly for interlocking between the at least one door panel and the ground operation hole. To mount the common linkage assembly, a first mounting plate 230 may be fixedly disposed on the switchgear cabinet 1. The common linkage assembly may include a door panel lock plate 220 movable relative to the first mounting plate 230, the door panel lock plate 220 cooperating with the cam 120 and associated with each door panel, and a linkage plate 210 for linkage with the cover plate 110. Specifically, the door panel lock plate 220 may be provided with an abutting portion 221 for cooperating with the cam 120, wherein when the switching mechanism is in the ground opening state, the cam 120 will abut against the abutting portion 221 of the door panel lock plate 220 and thus be in the stopping position, as shown in fig. 5, i.e., such abutment will disable movement of the door panel lock plate 220, which will keep the at least one door panel locked in the closed state; when the switching mechanism is in the ground-closing state, the cam 120 rotates and moves away from the abutment portion 221 of the door latch plate 220 and is thus in the non-stop position, so that the door latch plate 220 will be able to slide relative to the first mounting plate 230 and thus be able to release the latch of at least one door, as shown in fig. 2, 10 a-11. The linkage plate 210 may then have a linkage portion 211 for cooperating with the cover plate 110 to be linked with the cover plate 110, and have a locking portion associated with each door panel, the locking portion being arranged to be locked when the corresponding door panel is in the open state, thereby ensuring locking of the linkage plate 210, i.e. by locking the linkage plate 210, the linkage plate 210 cannot move any more, so that the cover plate 110 linked with the linkage plate 210 cannot move, more specifically, the cover plate 110 cannot be rotated from the closed position to the open position, thereby ensuring covering of the ground access hole by the cover plate 110, so that ground opening operation is not possible.

By providing all door panels of the switchgear cabinet 1 with a common linkage assembly for all door panels, it is possible to achieve an interlocking between each door panel and the ground access opening in a compact construction.

As shown in fig. 7 to 9, in some embodiments, the door panel locking plate 220 further includes a limiting portion 222, and the linkage plate 210 further includes a limiting engaging portion 212 for engaging with the limiting portion 222, wherein when the cover plate 110 is in the open position, the limiting engaging portion 212 abuts against the limiting portion 222 to stop the door panel locking plate 220 from sliding relative to the first mounting plate 230. That is, if the cover plate 110 is in the open position, the ground operation hole may be inserted by, for example, a ground operation wrench (not shown) and subjected to an opening and closing operation, and at this time, i.e., in a state where the cover plate 110 is kept open, it should be ensured that any door panel cannot be opened in order to ensure safety. The provision of such a stopper 222 and a stopper fitting portion 212 fitted to each other allows the door panel locking plate 220 to be locked with a simple structure, thereby locking the respective door panels. More specifically, as shown, the limit fitting part 212 of the linkage plate 210 may be disposed at an end thereof opposite to the linkage part 211, which may extend above the limit part 222 of the door panel lock plate 220 when the cover plate 110 is in the open position, so that the door panel lock plate 220 cannot move even if the cam 120 rotates to the non-stop position. That is, the stop action of the limit fitting portion 212 against the door panel lock plate 220 is in the same direction as the stop action of the cam 120 against the door panel lock plate 220.

As shown in fig. 4, 6-8, in some embodiments, the common linkage assembly may further comprise a second resilient member 240 connected between the linkage plate 210 and the first mounting plate 230, the second resilient member 240 being used for repositioning of the linkage plate 210. Specifically, when the cover plate 120 is switched from the covering position to the opening position, the cover plate 120 drives the linkage plate 210 to move in one direction (leftward in fig. 1, and rightward in fig. 4-8) relative to the first mounting plate 230 via the linkage portion 211, during which the second elastic member 240 stores energy; when the cover plate 110 is switched from the open position to the cover position, the second resilient member 240 releases energy to urge the linkage plate 210 to slide back in the opposite direction relative to the first mounting plate 230.

As shown in fig. 1-2, in a particular embodiment, the switchgear 1 may comprise a first door panel 300 and a second door panel 400 that switch between an open state and a closed state. More specifically, the first door panel 300 may be a fuse holder door, and the second door panel 400 may be a cable holder door. More specifically, the opening and closing of the first door panel 300 is performed by the first door panel 300 being wound around a pivot joint provided at the bottom thereof, which may be provided on a door frame, for example; the opening and closing of the second door panel 400 is performed by translating the second door panel 400 with respect to the door frame, for example, a plurality of hooking grooves may be provided on the door frame, a corresponding plurality of hooks may be provided on the second door panel, the second door panel 400 may be closed by translating the second door panel 400 with respect to the door frame to insert the plurality of hooks into the plurality of hooking grooves, and the second door panel 400 may be opened by translating the second door panel 400 with respect to the door frame to remove the plurality of hooks from the plurality of hooking grooves. In order to achieve interlocking between each of the first door panel 300 and the second door panel 400 and the ground operation hole, the switch cabinet 1 is also provided with a first linkage assembly and a second linkage assembly, respectively.

As shown in fig. 1 to 9, the switch cabinet 1 includes a first door panel 300, a first locking piece 380 may be disposed on the first door panel 300, the linkage plate 210 includes a first locking portion 213, the first linkage assembly may include a linkage plate locking plate 310, and the linkage plate locking plate 310 may include a driven portion 311 and a first locking mating portion 313. The driven part 311 of the linkage plate locking plate 310 is used for cooperating with the first locking piece 380 on the first door panel 300, so that the linkage plate locking plate 310 can move between a locking position and an unlocking position relative to the first mounting plate 230 as the first door panel 300 is switched between the opening state and the closing state, wherein in the locking position, the linkage plate locking plate 310 locks the linkage plate 210 by locking the first locking part 213 of the linkage plate 210, so that the linkage plate 210 can not move any more, and therefore the cover plate 110 can not move any more; in the unlocked position, linkage plate lockout plate 310 will release first lockout portion 213 of linkage plate 210 and thus no longer lockout linkage plate 210. Specifically, the first locking engagement portion 313 is configured to lock the first locking portion 213 of the linkage plate 210 when the linkage plate locking plate 310 is in the locked position, and to no longer lock the first locking portion 213 when the linkage plate locking plate 310 is in the unlocked position. More specifically, when the first door panel 300 is switched from the open state to the closed state, the first locking tab 380 will contact and drive the driven portion of the linkage plate locking plate 310, thereby driving the linkage plate locking plate 310 to move away from the first mounting plate 230, at which time the first locking engagement portion 313 will move with the linkage plate locking plate 310 away from the first mounting plate 230, so that the first locking engagement portion 313 is no longer aligned with and therefore no longer locks the first locking portion 213 of the linkage plate 210, i.e., at which time the linkage plate locking plate 310 is in the unlocked position; when the first door panel 300 is switched from the closed state to the open state, the first lock plate 380 will be disengaged from the driven portion 311 of the linkage plate locking plate 310, and at this time, the linkage plate locking plate 310 will be reset close to the first mounting plate 230, so that the first locking engagement portion 313 moves with the linkage plate locking plate 310 close to the first mounting plate 230, and thus the first locking engagement portion 313 aligns again and locks the first locking portion 213 of the linkage plate 210, i.e., the linkage plate locking plate 310 is in the locking position at this time. More specifically, the first locking portion 213 of the linkage plate 210 is in the form of a tab transverse to the main extension of the linkage plate 210, which contributes to achieving a compact design with a simple structure.

As shown in fig. 6, in some embodiments, to facilitate the return of the linkage plate lockout plate 310 from the unlocked position toward the locked position, the first linkage assembly further includes a first resilient member 340 connected between the linkage plate lockout plate 310 and the first mounting plate 230. The first elastic member 340 is configured such that, as the first door panel 300 is switched from the open state to the closed state, the first locking tab 380 pushes the linkage plate locking plate 310 to move from the locking position to the unlocking position through the driven portion 311 of the linkage plate locking plate 310, during which the first elastic member 340 stores energy; as the first door panel 300 switches from the closed state to the open state, the first resilient member 340 releases energy to urge the linkage plate latch plate 310 to move from the unlocked position to the locked position.

As shown in fig. 3 and 5, in some embodiments, the first locking tab 380 of the first door panel 300 is also configured to have another function of locking the first door panel 300 when it is in the closed position. To this end, the first locking tab 380 may be provided with a first locking groove 381, and the first linkage assembly may further include an elastic locking tab 270 fixedly disposed with respect to the first mounting plate 230, and when the first door panel 300 is in the closed state, the elastic locking tab 320 will be located in the first locking groove 381 for locking the first door panel 300. Because the elastic locking piece 270 has elasticity, when the first door panel 300 is switched from the closed state to the open state, the elastic locking piece 270 will be elastically deformed and can slide out of the first locking groove 381 along the first locking piece 380, and when the first door panel 300 is switched from the open state to the closed state, the elastic locking piece 270 will be able to slide into the first locking groove 381 along the first locking piece 380 again. To facilitate sliding of the resilient locking tab 270 into and out of the first locking groove 381 along the first locking tab 380, as shown in fig. 3 and 5, in some embodiments the first locking tab 380 also has a first projection 382 disposed distally relative to the first locking groove 381, the first projection 382 being defined by a first ramp 383 and a second ramp 384, the first ramp 383 being closer to the first locking groove 381 than the second ramp 384. Thus, as the first door panel 300 is switched from the closed state to the open state, the elastic locking piece 270 slides out of the first locking groove 381 along the first slope 383; as the first door panel 300 is switched from the open state to the closed state, the elastic locking piece 270 slides into the first locking groove 381 along the second slope 384 and the first slope 383 in succession. Thus, the first lock tab 380 on the first door panel 300 has a dual function of driving the linkage plate lock plate 310 to switch between the locked position and the unlocked position as the first door panel 300 is opened and closed, and locking the first door panel 300 when it is closed. This contributes to overall compactness.

As shown in fig. 2-3, 5, 10a-11, in some embodiments, to ensure the locking of the first door panel 300 in the closed position, a second locking tab 390 may be fixedly disposed on the first door panel 300, and the second locking tab may be provided with a second locking slot 391. At this time, a door locking part 223 may be provided on the door locking plate 220 such that when the first door panel 300 is in the closed state, the door locking part 223 will be located in the second locking groove 391 to lock the first door panel 300. Thus, providing the door panel locking portion 223 on the door panel locking plate 220 further contributes to achieving a very compact structure. More specifically, as shown in fig. 2-3, 5, 10a-11, in some embodiments, the second locking tab 390 can also have a second protrusion 392 disposed distally relative to the second lock slot 391, the second protrusion 392 being defined by a third ramp 393 and a fourth ramp 394, the third ramp 393 being closer to the second lock slot 391 than the fourth ramp 394. In this case, in order to allow the door locking portion 223 of the door locking plate 220 to enter and exit the second locking groove 391, the door locking plate 220 is further provided with a rotatable wheel 224, the wheel 224 is rotatably provided on one shaft 225 of the door locking plate 224, for example, and the wheel 224 is adapted to engage with the second protrusion 392. Specifically, as shown in fig. 10a to 10c, as the first door panel 300 is switched from the closed state to the open state, the third slope 393 will exert a force on the wheel 224, the wheel 224 rotates, and at the same time, the wheel 224 drives the door panel locking plate 220 to slide relative to the first mounting plate 230 in the first direction (upward direction in the figure) until reaching an extreme position, i.e., the extreme position is reached when reaching the top end of the second protrusion 392 (as shown in fig. 10 b), so that the door panel locking part 223 can come out of the second locking groove 391 as the first door panel 300 is opened, and then the door panel locking plate 220 slides back along the fourth slope 394 in a second direction opposite to the first direction; as the first door panel 300 is switched from the open state to the closed state, the fourth slope 394 will exert a force on the wheel 224, the driving wheel 224 rotates, and at the same time, the door panel locking plate 220 is driven by the wheel 224 to slide in the first direction relative to the first mounting plate 230 until the limit position, and then the door panel locking plate 220 slides back in the second direction and along the third slope 393, so that the door panel locking portion 223 enters the second locking groove 391 as the first door panel 300 is closed. This achieves further locking of the first door panel 300 by means of a very compact construction.

As shown in fig. 2, 5, 7, 9, and 11, in some embodiments, the door panel latch plate 220 may be provided with at least one first guide slot 226, the first mounting plate 230 is provided with at least one first guide tab 236, and the first guide slot 226 cooperates with the first guide tab 236 to guide the sliding of the door panel latch plate 220 relative to the first mounting plate 230. Alternatively, in an embodiment not shown, the door panel locking plate may be provided with at least one first guide projection, the first mounting plate correspondingly being provided with at least one first guide groove.

As mentioned above, the first door panel 300 may be a fuse tube door that can be pivoted at the bottom about a pivot connection provided on a door frame to switch between an open state and a closed state. In this case, the first locking tab 380 and the second locking tab 390 may be disposed on top of the first door panel. More specifically, the second locking tab 390 may be disposed proximate to a first side of the first door panel 300 and the second locking tab 380 is disposed proximate to a second side of the first door panel 300 opposite the first side to ensure effective locking of the first door panel 300 and prevent the first door panel 300 from being accidentally opened due to stress near either side.

As shown in fig. 1-2, 4, 11-13, in some embodiments, the switchgear panel 1 may further include a second door panel 400, and the switchgear panel 1 is further provided with a second linkage assembly that enables interlocking between the second door panel 400 and the ground access opening. In particular, the switchgear 1 may further include a fixedly disposed second mounting plate 250, and the second door panel 400 may include a driving part 410. The second linkage assembly may then comprise a driven plate 420 and a pivot lock plate 430, wherein the driven plate 420 may be moved, e.g. translationally moved or slid, relative to the second mounting plate 250 and the pivot lock plate 430 may be pivotally moved relative to the second mounting plate 250, more particularly about a pivot pin 251 fixedly disposed on the second mounting plate 250. The driven plate 420 may be provided with a first driven portion 421, and the first driven portion 421 is configured to cooperate with the driving portion 400 of the second door panel 400, so that the second door panel 400 can drive the driven plate 420 to move relative to the second mounting plate 250 through the cooperation between the driving portion 410 and the first driven portion 421 when the second door panel 400 is switched between the closed state and the open state. In a specific embodiment, the first follower 421 may be a protruding pin disposed on the follower plate 420, and the driving portion 410 is a protruding piece with a catch 411 fixedly disposed with respect to the second door panel 400, wherein the protruding pin can enter the catch 411, so that the follower plate 420 can be driven by the second door panel 400. Further, the driven plate 420 may also be provided with a locking portion 422 for cooperating with the pivot lock plate 430 and an actuating portion 427 for cooperating with the door plate locking plate 220, as described in detail below.

As shown in fig. 2, 4, 11-13, in some embodiments, the pivoting latch plate 430 is configured to pivot to an unlocked position and a locked position relative to the second mounting plate 250 as the second door 400 is switched between the closed state and the open state, and in particular, when the second door 400 is switched from the closed state to the open state, the pivoting latch plate 430 will pivot to the locked position, at which time the pivoting latch plate 430 will latch the driven plate 420, as described in detail below; and when the second door panel 400 is switched from the open state to the closed state, the pivoting lock plate 430 will pivot to the unlocked position such that the pivoting lock plate 430 will no longer be able to latch the driven plate 420, as described in detail below. For this reason, the pivotal lock plate 430 is provided with the engaging locking portions 432 such that when the second door panel 400 is switched from the closed state to the open state, the pivotal lock plate 430 will pivot from the unlocked position to the locked position, and the engaging locking portions 432 thereof then pivot with the pivotal lock plate 430 to a position capable of abutting against the locking portions 422 of the driven plate 420, and thus lock the driven plate 420. Specifically, the pivot lock plate 430 is mounted on the pivot pin 251 fixedly provided on the second mounting plate 250, so that the pivot lock plate 430 can achieve a state of stably locking the driven plate 420 after the mating locking portions 432 of the pivot lock plate 430 engage the locking portions 422 of the driven plate 420. Further, the pivoting lock plate 430 further includes a second driven portion 431, and when the second door 400 is switched from the open state to the closed state, the second door 400 pivots the pivoting lock plate 430 from the locking position to the unlocking position by cooperation between the driving portion 410 and the second driven portion 431 thereof, so that the cooperating locking portion 432 of the pivoting lock plate 430 releases the locking portion 422 of the driven plate 420 and thus releases the locking of the driven plate 420, so that the driven plate 420 can move with the movement of the second door 400.

In a more specific embodiment, as shown in fig. 2 and 11-13, to facilitate resetting of the pivot lock plate 430 from the unlocked position to the locked position, the second linkage assembly further includes a third resilient member 440 connected between the pivot lock plate 430 and the second mounting plate 250, wherein: during the switching of the second door panel 400 from the open state to the closed state, the third elastic member 440 stores energy as the pivoting lock plate 430 pivots from the locked position to the unlocked position; during the switching of the second door panel 400 from the closed state to the open state, the third elastic member 440 releases energy to urge the pivoting lock plate 430 to pivot from the unlocked position to the locked position. This ensures quick and timely locking of the driven plate 420.

As shown in fig. 2 and 12-13, in some embodiments, the driven plate 420 is provided with at least one second guide slot 426, the second mounting plate 250 is correspondingly provided with at least one second guide tab 256, and the second guide slot 426 cooperates with the second guide tab 256 to guide movement of the driven plate 420 relative to the second mounting plate 250. In an alternative not shown, the driven plate may be provided with at least one second guide projection and the second mounting plate may correspondingly be provided with at least one second guide slot.

As shown in fig. 4, 7, and 9, in some embodiments, the door latch plate 220 further includes an actuation engagement portion 227 for engaging an actuation portion 427 provided on the driven plate 420. Specifically, when the cam 120 is at the stop position, the actuation fitting portion 227 of the door panel lock plate 220 blocks the actuation portion 427 of the driven plate 420 to hold the second door panel 400 in the closed state; when the second door 400 is switched from the closed state to the open state, the actuating portion 427 of the driven plate 420 will abut the actuating mating portion 227 of the door latch plate 220 to enable driving the door latch plate 220 to slide in the first direction relative to the first mounting plate 230. In this manner, a second linkage assembly for the second door panel 400 may be associated with the aforementioned common linkage assembly to effect interlocking of the second door panel 400 with the ground access opening.

As shown in fig. 6-9, in some embodiments, linkage plate 210 further includes a second detent 218, such as the end portion of linkage plate 210 opposite linkage portion 211, door latch plate 220 further includes a second latch mating portion 228, for example, in the form of a tab, wherein when the second door panel 400 is in the open state, the second latch mating portion 228 moves with the door panel latch plate 220 into alignment with the second latch portion 218, to latch the linkage plate 210, that is, if an attempt is made to move the cover plate 110 interlocked with the interlocking plate 210 through the interlocking part 211, the linkage plate 210 is made to be passive because the second locking portion 218 of the linkage plate 210 is locked by the second locking engagement portion 228 of the door panel locking plate 220, and thus the cover plate 110 is made to be passive, that is, the cover plate 110 cannot be opened, thereby preventing the ground operation wrench from being inserted into the ground operation hole to perform the opening and closing operation when the second door panel 400 is opened; when the second door panel 400 is in the closed position, the second latch engagement portion 228 moves with the door panel latch plate 220 out of alignment with the second latch portion 218 to no longer latch the linkage plate 210. Thereby, locking of the link plate 210 and thus the cover plate 110 and the ground operation hole when the second door 400 is opened is achieved with a compact and simple structure.

As shown in fig. 2, 4, 7 and 11, in some embodiments, a fourth elastic member 450 is disposed between the door latch plate 220 and the driven plate 420, and the fourth elastic member 450 may be used for resetting the door latch plate 220.

Specifically, in the case where it is only necessary to open the first door panel 300 without opening the second door panel 400, when the first door panel 300 is switched from the closed state to the open state, as described above, the door panel locking plate 220 will slide in a first direction relative to the first mounting plate 230 due to the force exerted on the wheel 224 by the third slope 393 of the second locking tab 390 of the first door panel 300, during which the fourth elastic member 450 may store energy, and when the door panel locking plate 220 slides to an extreme position, i.e., when the wheel reaches the top end of the second protrusion 392, the door panel locking plate 220 will slide back in a second direction opposite to the first direction, at which time the fourth elastic member 450 may release energy to actuate the sliding back of the door panel locking plate 220. Then, when the first door panel 300 is switched from the open state to the closed state, as shown above, the door panel locking plate 220 will slide in the first direction relative to the first mounting plate 230 due to the force exerted on the wheel 224 by the fourth slope 394 of the second locking tab 390 of the first door panel 300, during which the fourth elastic member 450 stores energy, and when the door panel locking plate 220 slides to the extreme position, i.e., when the wheel reaches the top end of the second protrusion 392, the door panel locking plate 220 will slide back in the second direction and along the third slope 393, at which time the fourth elastic member 450 releases energy to urge the door panel locking plate 220 to slide back and urge the door panel locking part 223 to slide back into the second locking groove 391.

In the case where it is only necessary to open the second door panel 400 without opening the first door panel 300, when the second door panel 400 is switched from the closed state to the open state, as described above, the actuating portion 427 of the driven plate 420 will bring the actuating engagement portion 227 of the door panel latch plate 220 and thus the door panel latch plate 220 to slide in the first direction relative to the first mounting plate 230, and there is no relative movement between the door panel latch plate 220 and the driven plate 420, and the fourth elastic member 450 does not function. When the second door 400 is switched from the open state to the closed state, the driven plate 420 slides in the second direction with respect to the second mounting portion 250 due to the first driven portion 421 thereof being driven by the driving portion 410 of the second door 400, and then the actuating portion 427 of the driven plate 420 no longer acts on the actuating engagement portion 227 of the door panel locking plate 220, but the driven plate 420 pulls the door panel locking plate 220 to be reset, i.e., slides back in the second direction with respect to the first mounting portion 230, through the fourth elastic member 450.

In addition, the provision of the fourth elastic member 450 also allows the first door panel 300 and the second door panel 400 to be opened simultaneously. Thus, by providing the fourth elastic member 450, the restoration of the door panel locking plate 220 is achieved in a very compact structure.

As mentioned above, this second door panel 400 may be a cable chamber door provided with a hook, on the door frame of the switchgear cabinet a hooking slot is provided, into and out of which the hook can translate, so that the second door panel 400 switches to the closed state and to the open state, respectively.

Therefore, the utility model provides a cubical switchboard has ensured the interlocking between every door plant and the ground connection handle hole thereof: when the switch mechanism is in a grounding opening state, each door panel can not be opened but only can be in a closing state; under the condition that the grounding operation hole is not covered by the cover plate, each door plate can not be opened and only can be kept in a closed state; the door plate is allowed to be opened only when the switch mechanism is in a grounding and closing state and the grounding operation hole is covered by the cover plate.
