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 panel and the fuse tube door panel are ensured to be in a closed state and cannot be opened; only when the switch mechanism is in a 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. Current interlocking structure relates to too much parts, and easy bite influences customer experience, and the compactness is not good enough.

As shown in fig. 1-2, according to an embodiment of the present invention, the proposed switchgear 1 comprises at least one door panel 300, 400 and a switching mechanism 100, the switching mechanism 100 is at least capable of switching between a ground closing state and a ground opening state, and the at least one door panel 300, 400 is capable of switching between an open state and a closed state, and only when the switching mechanism 100 is in the ground closing state, any of the door panels 300, 400 of the switchgear 1 is capable of switching from the closed state to the open state, and if the switching mechanism 100 is in the ground opening state, any door panel 300, 400 of the switchgear 1 is not allowed to open, so as to ensure safety. In one particular embodiment, the switch mechanism 100 may be a three-position mechanism.

As shown in fig. 1 and 3 to 4, the switch mechanism 100 is provided with at least a ground operating hole and a cover plate 110, and the cover plate 110 is capable of switching between a covering position covering the ground operating hole and an opening position opening the ground operating hole, and the ground operating hole is fully exposed only when the cover plate 110 is in the opening position, and allows, for example, a ground operating wrench (not shown) to be inserted thereinto for a corresponding switching operation. More specifically, a return spring (not shown in the drawings) for urging the cover plate 110 to return when the cover plate 110 is in the open position may be provided between the cover plate 110 and the main body of the switch mechanism 100. 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 100 between a ground closing state and a ground opening state. More specifically, when the switching mechanism 100 is in the ground opening state, the cam 120 is in the stop position, as shown in fig. 3; when the switching mechanism 100 is in the ground-on state, the cam 120 is in the non-stop position, as shown in fig. 4. And more specifically, when the cam 120 is in the stop position, any door panel of the switchgear cabinet 1 will not be able to be opened, whereas only when the cam 120 is in the non-stop position, the door panel of the switchgear cabinet is allowed to be opened.

That is, in such a switchgear 1, if the switching mechanism 100 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 should be ensured that the switching mechanism 100 is not switched from the ground-on state to the ground-off state, which can be achieved by ensuring that the ground-operating hole is not opened, and more specifically, by ensuring that the cover plate 110 is held in the closed position.

To this end, as shown in fig. 1-4 and 6-16, 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 300, 400 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 — it should be noted that the first mounting plate 230 may be a unitary member, or may comprise a plurality of portions disposed separately from one another, each of which is fixedly disposed relative to the switchgear cabinet 1. The common linkage assembly may include a linkage locking plate 220 and a linkage plate 210 movable relative to the first mounting plate 230, the linkage locking plate 220 cooperating with the cam 120 and associated with each door panel 300, 400, the linkage plate 210 for linkage with the cover plate 110.

Specifically, the interlocking lock plate 220 may be provided with a first abutting portion 221 for cooperating with the cam 120, wherein when the switching mechanism 100 is in the ground opening state, the cam 120 will abut against the first abutting portion 221 of the interlocking lock plate 220 and thus be in the stopping position, as shown in fig. 3, i.e., such abutment will make the interlocking lock plate 220 unable to be displaced, which will keep each of the at least one door panels 300, 400 locked in the closed state; when the switching mechanism 100 is in the ground-closing state, the cam 120 rotates and moves away from the first abutment 221 of the linkage lock plate 220 and is thus in the non-stop position, as shown in fig. 4, so that the linkage lock plate 220 will be able to displace relative to the first mounting plate 230 and thus be able to release the locking of the at least one door panel 300, 400. That is, the interlock lock plate 220 may occupy a first position corresponding to the door panel closed state and a second position corresponding to the door panel open state, and may be displaced relative to the first mounting plate 230 between the first position and the second position. In a particular embodiment, as shown in figures 6-7 and 12, the sliding of the linkage locking plate 220 with respect to the first mounting plate 230 is achieved by the cooperation of at least one first guide slot 226 provided in the linkage locking plate 220 with a corresponding at least one guide projection 426 comprised by the switchgear cabinet 1. 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 operating opening in a compact structure.

As shown in fig. 12, fig. 12 corresponds to the first door panel 300 and the second door panel 400 described below both being in an open state, the linkage plate 210 may have a linkage portion 211 for cooperating with the cover plate 110 to be linked with the cover plate 110, and a common locking portion 213 associated with each of the at least one door panels 300, 400, the common locking portion 213 being configured to be locked when either of the at least one door panels 300, 400 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 be moved, more specifically, the cover plate 110 cannot be rotated from the closed position to the open position, thereby ensuring covering of the cover plate 110 against the ground operation hole, so that ground opening operation is not possible. In some embodiments, as shown in fig. 7 and 12, the interlocking lock plate 220 may include a lock engagement portion 223 for engaging with the common lock portion 213 of the interlocking plate 210, such that when any of the at least one door panels 300, 400 is in an open state, i.e., the interlocking lock plate 220 is in a second position corresponding to the door panel open state, the lock engagement portion 223 of the interlocking lock plate 220 is aligned with the common lock portion 213 of the interlocking plate 210110 to lock the interlocking plate 210; when all of the at least one door panels 300, 400 are in the closed state, i.e., the interlocking lock plate 220 is in the first position corresponding to the closed state of the door panels, the latch mating portions 223 of the interlocking lock plate 220 are no longer aligned with the common latch portion 213 of the interlocking plate 210, so as to no longer latch the interlocking plate 210. More specifically, as shown, common lockout portion 213 of linkage plate 210 may be an end of linkage plate 210 opposite linkage portion 211.

That is, as described above, when the switching mechanism 100 is switched from the ground opening state to the ground closing state, the cam 120 rotates and leaves the first abutting portion 221 of the interlocking lock plate 220 and is thus in the non-stop position, so that the interlocking lock plate 220 can be displaced in the first displacement direction with respect to the first mounting plate 230, for example, because of being driven by the door panel 300, 400 being opened, and can slide upward in the drawing with respect to the first mounting plate 230, which causes the latch fitting portion 223 of the interlocking lock plate 220 to slide to a position aligned with the common latch portion 213 of the interlocking plate 210 with the interlocking lock plate 220, so that the movement of the interlocking plate 213 can be blocked, and in fig. 12, the movement of the interlocking plate 210 to the right is blocked, so that the cover plate 110 interlocked with the interlocking plate 210 cannot rotate and thus remains covering the ground operating hole, ensuring safety. When it is desired to switch the switching mechanism 100 from the ground closing state to the ground opening state, the door panels 300, 400 in the open state are closed and thus the interlocking locking plate 220 may be allowed to be displaced in a second displacement direction (downward direction in the figure) opposite to the first displacement direction, which causes the locking engagement portion 223 of the interlocking locking plate 220 to slide with the interlocking locking plate 220 to a position no longer aligned with the common locking portion 213 of the interlocking plate 210, and thus no longer being able to block the movement of the interlocking plate 210 (rightward direction in the figure), at which time the cover plate 110 interlocked with the interlocking plate 210 may be rotated and thus may open the ground operating hole, so that for example an operating wrench (not shown) may be inserted into the ground operating hole to perform, for example, a ground opening operation of the ground operating hole, at which time the cam 120 will rotate back and again abut against the first abutment portion 221 of the interlocking locking plate 220.

As shown in fig. 6, wherein fig. 6 corresponds to the first door panel 300 and a second door panel 400 to be described later being in a closed state, in some embodiments, the interlocking locking plate 220 may include a first limiting portion 222, and the interlocking plate 210 may correspondingly include a first limiting engagement portion 212 for engaging with the first limiting portion 222, so that when the cover plate 110 is in the open position, the first limiting engagement portion 212 of the interlocking plate 210 engages with the first limiting portion 222 of the interlocking locking plate 220 to stop the displacement of the interlocking locking plate 220 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 and subjected to an opening and closing operation, and at this time, i.e., in a case where the cover plate 110 is kept open, it should be ensured that any door panel 300, 400 cannot be opened in order to ensure safety. The provision of such first limit fitting portions 222 and 212 fitted to each other allows the interlocking lock plate 220 to be locked with a simple structure, thereby locking the respective door panels 300 and 400. More specifically, as shown, the first limit fitting portion 212 of the linkage plate 210 may be disposed at an end thereof opposite to the linkage portion 211, which may extend above the first limit portion 222 of the linkage lock plate 220 when the cover plate 110 is in the open position, thereby preventing upward movement of the linkage lock plate 220 (it should be noted that this orientation is merely illustrative and not limiting), so that the linkage lock plate 220 cannot move even if the cam 120 is rotated to the non-stop position. That is, the stopping action of the first limit fitting part 212 against the interlock plate 220 is in the same direction as the stopping action of the cam 120 against the interlock plate 220.

As shown in fig. 1, 6, 8, 12, 13, in some embodiments, the common linkage assembly may further include a sixth resilient member 214 connected between linkage plate 210 and first mounting plate 230, the sixth resilient member 214 being for return of linkage plate 210, such as an extension spring. More specifically, when the cover plate 110 is switched from the covering position covering the ground operation hole to the opening position opening the ground operation hole, the cover plate 110 moves the linkage plate 210 relative to the first mounting plate 230 via the linkage portion 211 (to the right in fig. 6, 8, 12, 13), at this time, the sixth elastic member 214 may store energy, for example, it may be stretched to store elastic potential energy; when the cover plate 110 is switched from the open position to the cover position, the sixth resilient member 214 will release its energy and thus urge the linkage plate 210 to slide back, i.e., reset, relative to the first mounting plate 230 (to the left in fig. 6, 8, 12, 13). Thus, the sixth elastic member 214 may ensure a quick return of the linkage plate 210 and thus a quick closing of the cover plate 110, when needed.

As shown in fig. 6, 8, 12, 13, in some embodiments, the linkage plate 210 may be unitary and have a first extension 215 and a second extension 217 offset relative to each other and connected to each other via an intermediate portion 216. More specifically, as shown, the first extension 215 and the second extension 217 are parallel and offset from each other. The link 211 of the link plate 210 is provided as a protrusion protruding with respect to the first extension 215. The sixth elastic member 214 is connected between a protrusion protruding with respect to the second extension 217 and the first mounting plate 230. The common latch portion 213 of the linkage plate 210 may be the end of the second extension 217 opposite the first extension 215. The first stop-fit portion 212 of the linkage plate 210 may be a lower edge at the end of the second extension 217 opposite the first extension 215. This is advantageous for achieving a very compact construction.

As shown in fig. 6-7 and 12, in some embodiments, the locking engagement portion 223 and the first retention portion 222 of the interlocking lock plate 220 are both defined by the same tab 224 provided on the interlocking lock plate 220, wherein one of the major faces of the tab 224 constitutes the locking engagement portion 223 and the upper edge of the tab 224 constitutes the first retention portion 222. This is advantageous for achieving a very compact construction.

In more particular embodiments, as particularly shown in fig. 7, the linkage lockout plate 220 may be configured to have at least a vertical main extension 227 and a lateral extension 228 and a connection therebetween, the vertical main extension 227 and the lateral extension 228 may be integrally formed, or may be separate components assembled together (e.g., via riveting, threading, etc.), wherein the tab 224 may be provided to extend from one side edge of the vertical main extension 227 in parallel with the vertical main extension 227, and the lateral extension 228 may define the first abutment 221 described above. Further, the at least one first guide slot 226 may be provided in the vertical main extension 227 for cooperating with a corresponding at least one first guide tab 426 provided on another component to guide displacement of the ganglock plate 220 relative to the first mounting plate 230. More specifically, as shown in fig. 6 and 8, the interlocking lock plate 220 may also be provided with a vertical guide plate 229 parallel to and spaced apart from the vertical primary extension 227, and the vertical guide plate 229 may be provided therein with at least one second guide slot for cooperating with a corresponding at least one second guide tab fixedly disposed relative to the first mounting plate 230 to further guide the sliding of the interlocking lock plate 220 relative to the first mounting plate 230. Of course, the arrangement of the first guide groove and the first guide protrusion may be reversed, i.e. the first guide protrusion may be arranged on the vertical main extension 227, and the first guide groove may be arranged on the other components; similarly, the arrangement of the second guide groove and the second guide protrusion can be reversed.

As shown in fig. 2 and 5, in a specific embodiment, the switchgear 1 may include 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 illustrated in fig. 2, 6 and 8-17, the switchgear panel 1 comprises a first door panel 300 and a first linkage assembly associated with the first door panel 300, the first linkage assembly comprising at least a first linkage subassembly. The linkage locking plate 220 is further provided with a linkage follower 225; more specifically, in the above-described embodiment in which the linkage lock plate 220 includes the vertical main extension 227 and the lateral extension 228, the linkage follower portion 225 of the linkage lock plate 220 is provided in the form of a tab bent with respect to the vertical main extension 227, which may extend parallel to the lateral extension 228, for example. A first drive latch 310 is disposed on first door panel 300, e.g., disposed transverse to a main panel of first door panel 300, and e.g., disposed on top of first door panel 300, and a first linkage subassembly is associated with first drive latch 310. The first linkage subassembly may include a first rotating plate 340 and a first sliding plate 350. The first rotating plate 340 is, for example, pivotably provided on the first mounting plate 230 about a first pivot pin 231 fixedly provided on the first mounting plate 230, and is provided with a linkage driving portion 345 for engaging with the linkage driven portion 225 of the linkage locking plate 220, a first driven portion 341 for engaging with the first driving locking plate 310, and a second abutting portion 342, a first actuating portion 343, and a locking groove 344. The first sliding plate 350 is configured to slide relative to the first mounting plate 230, for example, as shown in fig. 9-11, at least one third guide groove 356, three shown in the figures, may be provided in the first sliding plate 350, at least one third guide protrusion 236 is correspondingly provided on the first mounting plate 230, and the sliding of the first sliding plate 350 relative to the first mounting plate 230 is guided by the cooperation of the third guide protrusion 236 and the third guide groove 356. As shown in the drawing, the first sliding plate 350 is provided with a locking portion 351 which is engaged with the second contact portion 342, the first actuating portion 343, and the locking groove 344 of the first rotating plate 340. Wherein:

when the first door panel 300 is in the closed state, the second abutting portion 342 of the first rotating plate 340 abuts against the locking portion 351 of the first sliding plate 350, as shown in fig. 15;

during the switching of the first door panel 300 from the closed state to the open state, the first driving locking plate 310 of the first door panel 300 applies a driving force to the first driven portion 341 of the first rotating plate 340 and thus drives the first rotating plate 340 to pivot in a first pivot direction, counterclockwise in the drawing, such that the first actuating portion 343 of the first rotating plate 340 urges the first sliding plate 350 to slide relative to the first mounting plate 230 via the locking portion 351 of the first sliding plate 350, upward in fig. 10, and such that the linkage driving portion 345 of the first rotating plate 340 applies a driving force to the linkage driven portion 225 of the linkage locking plate 220 to drive the linkage locking plate 220 to displace in a first displacement direction (upward in the drawing); when the first door panel 300 is in the open state, the locking portion 351 of the first sliding plate 350 is locked in the locking groove 344 of the first rotating plate 340, thereby locking the first rotating plate 340, as shown in fig. 16;

during the switching of the first door panel 300 from the open state to the closed state, the first driving locking plate 310 of the first door panel 300 drives the first rotating plate 340 to pivot in a second pivot direction (clockwise direction in the drawing) opposite to the first pivot direction via the first driven portion 341 of the first rotating plate 340, so that the locking portion 351 of the first sliding plate 350 leaves the locking groove 344 of the first rotating plate 340, and then the first rotating plate 340 actuates the first sliding plate 350 to slide via the first actuating portion 343 thereof while the interlocking locking plate 220 is displaced in a second displacement direction (downward in the drawing) opposite to the first displacement direction.

It should be noted that the driving action of the interlocking driving part 345 of the first rotating plate 340 on the interlocking driven part 225 of the interlocking lock plate 220 as described above occurs when the first door panel 300 is opened only when the other door panels (such as the second door panel 400 to be described later) than the first door panel 300 are in the closed state. Otherwise, when other door panels (such as the second door panel 400 described below) than the first door panel 300 are already in the open state, the interlocking lock plate 220 is already in the second position (the upper position shown in the figure) corresponding to the door panel open state, and at this time, the opening of the first door panel 300 will not exert a driving action on the interlocking driven part 225 of the interlocking lock plate 220 via the interlocking driving part 345 of the first rotating plate 340.

As shown in fig. 14-16, in some embodiments, the first actuating portion 343 of the first rotating plate 340 may be provided in the form of a convex surface such that the first sliding plate 350 may first undergo sliding leftward in the drawing, undergo partial resetting rightward in the drawing after passing an apex of the convex surface when the first door panel 300 is switched between the closed state (fig. 10, 14, and 15) and the open state (fig. 11 and 16). Specifically, during the switching of the first door panel 300 from the closed state to the open state, the first sliding plate 350 is caused to have a first sliding stroke in the first sliding direction (leftward in fig. 14 to 15) and a first returning stroke in the second sliding direction opposite to the first sliding direction via the first actuating portion 343 of the first rotating plate 340, and at the end of the first returning stroke, the locking portion 351 of the first sliding plate 350 enters and is locked in the locking groove 344 of the first rotating plate 340, which makes it possible to keep the first sliding plate 350 and the first rotating plate 340 stationary, thereby holding the interlocking lock plate 220 at a position corresponding to the open state of the first door panel 300, i.e., the second position, via the supporting action of the interlocking driving portion 345 of the first rotating plate 340 against the interlocking driven portion 225 of the interlocking lock plate 220 (upward supporting action in the drawing); as described above, in this position, the latch engagement portions 223 of the interlock latch plates 220 will align with the common latch portions 213 of the interlock plates 210, so that the interlock plates 210 cannot move and thus the cover plates 210 cannot open the ground access apertures. During the switching of the first door panel 300 from the open state (fig. 16) to the closed state (fig. 14 and 15), the first sliding plate 350 may be caused to have a second sliding stroke in the first sliding direction (leftward in fig. 16) and a second returning stroke in the second sliding direction (rightward in the drawing) via the first actuating portion 343 of the first rotating plate 340, and at the end of the second returning stroke, the second abutting portion 342 of the first rotating plate 340 abuts against the locking portion 351 of the first sliding plate 350; during this time, if the other door panels are in the closed state, since the interlocking driving part 345 of the first rotating plate 340 rotates clockwise with the first rotating plate 340, and along with this, the interlocking locking plate 220 returns to the position corresponding to the closed state of the first door panel 300 with respect to the first mounting plate 230, i.e., the first position, the locking engagement part 223 of the interlocking locking plate 220 is also no longer aligned with the common locking part 213 of the interlocking plate 210, and thus can no longer block the movement of the interlocking plate 210 and thus can no longer block the opening of the cover panel 110.

As shown in fig. 14, in a specific embodiment, the second abutting portion 342 of the first rotating plate 340 is provided with a slope 3421, and the slope 3421 is designed such that when the first door panel 300 is pulled outward, the slope 3421 pushes the first sliding plate 350 and generates a certain resistance so that the first door panel 300 does not fall down by itself without being locked.

As shown in fig. 5, 9 and 15, in a more specific embodiment, the first driving locking piece 310 of the first door panel 300 may be provided with a first locking notch 311, and the first driven portion 341 of the first rotating plate 340 is inserted into the first locking notch 311 to lock the first door panel 300 when the first door panel 300 is in the closed state; when the first door panel 300 is in the open state, the first driven part 341 of the first rotating plate 340 is separated from the first locking notch 311 of the first driving locking piece 310. For example, the first driven part 341 of the first rotating plate 340 and the rest of the first rotating plate 340 are provided with slots 346, allowing the first driven part 341 to be inserted into the first locking notch 311. More specifically, the first driving locking piece 310 of the first door panel 300 may include a door closing driving part 312 defined by an end portion and a door opening driving part 313 defined by one inner edge of the first locking notch 311; the first driven portion 341 of the first rotating plate 340 may include a door closing driven portion 3412 engaged with the door closing driving portion 312 of the first driving locking plate 310 and a door opening driven portion 3413 engaged with the door opening driving portion 313 of the first driving locking plate 310. When the first door panel 300 is switched from the closed state to the open state, the door opening driving portion 313 of the first driving locking piece 310 drives the door opening driven portion 3413 of the first driven portion 341 of the first rotating plate 340 and thus drives the first rotating plate 340 to pivot in the first pivoting direction; when the first door panel 300 is switched from the open state to the closed state, the door-closing driving portion 312 of the first driving lock plate 310 drives the door-closing driven portion 3412 of the first driven portion 341 of the first rotation plate 340, and thus drives the first rotation plate 340 to pivot in the second pivot direction.

As shown in fig. 9 and 14-16, in a more specific embodiment, the first linkage subassembly may further include a first resilient member 352, such as an extension spring, connected between the first rotating plate 340 and the first sliding plate 350, the first resilient member 352 being configured to store energy during the first and second sliding strokes and release energy during the first and second return strokes to facilitate return of the first sliding plate 350. More specifically, the first mounting plate 230 may be provided with a second limit stop portion 237, which is, for example, a convex pin disposed on the first mounting plate 230, and the first rotating plate 340 correspondingly includes a second limit stop engagement portion 347, which is, for example, a partial edge portion of the first rotating plate 340, and the second limit stop engagement portion 347 is configured to engage with the second limit stop portion 237 to limit the pivoting stroke of the first rotating plate 340 in the first pivoting direction. That is, when the first door panel 300 is switched from the closed state to the open state, the engagement between the second limit stop 237 on the first mounting plate 230 and the second limit engagement 347 of the first rotating plate 340 after the first door panel 300 has been opened ensures that the first rotating plate 340 no longer continues to pivot in the first pivot direction, i.e., when the first rotating plate 340 has reached its maximum pivot travel in the counterclockwise direction. In addition, the first elastic member 352 may also be configured to have a holding effect on the first rotating plate 340 when the first door panel 300 is at the maximum pivoting stroke, i.e., the elastic potential energy of the first elastic member 352 together with the cooperation between the second limit stop 237 and the second limit fitting 347 further ensures that the first rotating plate 340 remains stationary at the maximum pivoting stroke thereof in the counterclockwise direction.

As shown in fig. 6, 8 and 10-13, in some embodiments, the first linkage subassembly may further include a second resilient member 353, such as an extension spring, connected between the first mounting plate 230 and the first sliding plate 340, the second resilient member 353 being configured to store energy during the first and second sliding strokes and to release energy during the first and second return strokes to facilitate return of the first sliding plate 350. Note that in the case where the first and second elastic members 352 and 353 are provided at the same time, it is preferable that the first and second elastic members 352 and 353 are provided at opposite sides of the first sliding plate 350, respectively, to achieve smooth reset actuation of the first sliding plate 350.

As shown in fig. 5-6 and 8-10, where fig. 6, 8-10 correspond to first door panel 300 being in a closed state and fig. 11-13 correspond to first door panel 300 being in an open state, first door panel 300 further includes a second drive latch 320 and a third drive latch 330. The first linkage assembly also includes a second linkage sub-assembly that is associated with a second drive lock tab 320 and a third drive lock tab 330. The second linkage mover assembly includes a second rotation plate 360 and a second sliding plate 370, the second rotation plate 360 being pivotably disposed on the first mounting plate 230, e.g., about a second pivot pin 232 fixedly disposed on the first mounting plate 230, the second sliding plate 370 being slidably disposed relative to the first mounting plate 230, e.g., by the engagement of guide slots and guide tabs to guide the sliding of the second sliding plate 370 relative to the first mounting plate 230. The second rotation plate 360 is provided with a second driven portion 361 to be engaged with the second drive locking plate 320, and is provided with a second actuating portion 362. The second sliding plate 370 is provided with a second actuation fitting portion 372 for fitting with the second actuation portion 362 of the second rotating plate 360 and a locking end portion 373 for fitting with the third drive locking plate 330. Wherein, during the switching of the first door panel 300 from the open state (fig. 11-13) to the closed state (fig. 6, 8-10), the second driving locking plate 320 drives the second driven portion 361 of the second rotating plate 360 to pivot the second rotating plate 360 in the third pivoting direction, which is clockwise in the figures, and thus causes the second actuating portion 362 of the second rotating plate 360 to apply an actuating force to the second actuating mating portion 372 of the second sliding plate 370 to actuate the second sliding plate 370 to slide in the lock-in direction, which is leftward in the figures, so that the locking end portion 373 is locked by the third driving locking plate 330, thereby ensuring the locking of the first door panel 300 in the closed state; during the switching of the first door panel from the closed state (fig. 6, 8-10) to the open state (fig. 11-13), the second driving locking plate 320 releases the second driven portion 361 of the second rotating plate 360 and thus the second actuating portion 362 of the second rotating plate 360 releases the second actuating engagement portion 372 of the second sliding plate 370, and at this time, the third driving locking plate 330 drives the locking end portion 373 of the second sliding plate 370 to slide the second sliding plate 370 in the unlocking direction (rightward in the drawing) opposite to the locking-in direction and disengage the locking end portion 373 of the second sliding plate 370 from the third driving locking plate 330, thereby unlocking the first door panel 300, while the second rotating plate 360 pivots in the fourth pivoting direction (counterclockwise in the drawing) opposite to the third pivoting direction.

As shown in fig. 5, 8-10, in some embodiments, the second driving locking tab 320 of the first door panel 300 is provided with a concave portion 321, and the second driven portion 361 of the second rotating plate 360 is configured to form-fit with the concave portion 321, such that the second driving locking tab 320 can drive the second driven portion 361 of the second rotating plate 360 via the concave portion 321 during switching of the first door panel 300 from the open state (fig. 11-13) to the closed state (fig. 6, 8-10). When the second door panel 300 is closed, the concave portion 321 of the second driving locking plate 320 applies a force component in the third pivoting direction to the second driven portion 361 of the second rotating plate 360, so that the second rotating plate can be pivoted; the concave portion 321 facilitates a component in the fourth pivoting direction to be applied to the second rotating plate 360 when the second door panel 300 is opened, thereby facilitating the pivoting of the second rotating plate 360.

As shown in fig. 5-6 and 8-9, in some embodiments, the third drive lock tab 330 is provided with a second locking notch 331, which is, for example, rectangular. Wherein, during the switching of the first door panel 300 from the open state to the closed state, the locking end 373 of the second sliding plate 370 may enter the second locking notch 331 to lock the first door panel 330; during the switching of the first door panel 300 from the closed state to the open state, the locking end 373 of the second sliding plate 370 will be disengaged from the second locking notch 331 to release the locking of the first door panel 300. More specifically, the locking end 373 of the second sliding plate 370 may be provided with a ramp portion 374, as shown in fig. 17, such that when the first door panel 300 is switched from the closed state to the open state, one inner edge 3311 of the second locking slot 331 presses against the ramp portion 374 of the locking end 373 to apply a force component in the unlocking direction to the second sliding plate 370 through the ramp portion 374, and thus the second sliding plate 370 is driven to slide in the unlocking direction, making it easier to unlock the first door panel 300. In addition, the ramp portion 374 allows the locking end 373 of the second sliding plate 370 to have a wedge form, so that a more firm locking force is applied to the first door panel 300 in the closed state of the first door panel 300, thereby facilitating the locking of the first door panel 300 more tightly. More specifically, when the first door panel 300 is closed in position, the tip 375 of the locking end 373 of the second sliding plate 370 will abut against a stop fixedly disposed with respect to the first mounting plate 230, thereby limiting the sliding formation of the second sliding plate 370 in the lock-in direction.

In this case, it is preferable that the second rotating plate 360 is provided such that, when the first door panel 300 is closed, the second rotating plate 360 has an idle rotation stroke before the second actuating portion 362 of the second rotating plate 360 starts to drive the second sliding plate 370, so that the second actuating portion 362 of the second rotating plate 360 can drive the second sliding plate 370 to slide in the locking direction after the second rotating plate 360 rotates by a certain angle. Thus, after the third drive lock plate 330 of the first door panel 300 has moved inward to some extent, the second sliding plate 370 is moved in the lock-in direction again, thereby ensuring that the locking end 373 can be inserted into the second locking notch 331 in the third drive lock plate 330 without any interference in movement therebetween.

As shown in fig. 8-9 and 12-13, in some embodiments, the second linkage mover assembly may further include a third elastic member 364 connected between the first mounting plate 230 and the second rotating plate 360, the third elastic member 364 being, for example, a tension spring, and configured to store energy during switching of the first door panel 300 from the open state to the closed state, and release energy during switching of the first door panel 300 from the closed state to the open state to cause the second rotating plate 360 to reset in the fourth pivoting direction, which may make it easier and faster for the second rotating plate 360 to clear a space allowing the second sliding plate 370 to slide in the unlocking direction.

As shown in fig. 8-9 and 12-13, in some embodiments, the second linkage sub-assembly further includes at least one fourth elastic member 376 connected between the first mounting plate 230 and the second sliding plate 370, the fourth elastic member 376 being, for example, a tension spring, and being configured to store energy during switching of the first door panel 300 from the open state to the closed state and release energy during switching of the first door panel 300 from the closed state to the open state to urge the second sliding plate 370 to return in the unlocking direction. Preferably, one fourth elastic member 376 may be provided on each of opposite sides of the second sliding plate 370 as shown in the drawing, to achieve a balanced and smooth reset actuation of the second sliding plate 370.

As particularly shown in fig. 17, in a specific embodiment, the second sliding plate 370 may be configured to include a main extension portion 371 disposed in parallel with the main panel of the first door panel 300 in the closed state, a first bent portion bent at a first end portion with respect to the main extension portion 371, and a second bent portion bent at a side portion near a second end portion opposite to the first end portion with respect to the main extension portion 371, the second actuation engagement portion 372 being disposed on the first bent portion, and the locking end portion 373 being disposed on the second bent portion. More specifically, the second sliding plate 370 may be provided with at least one fourth guide groove 377, and correspondingly, at least one fourth guide protrusion 233 is provided on the first mounting plate 230, and the sliding of the second sliding plate 370 with respect to the first mounting plate 230 is guided by the cooperation of the fourth guide groove 377 and the fourth guide protrusion 233. Note that the arrangement of the fourth guide groove 377 and the fourth guide protrusion 233 may be reversed.

As mentioned above, the first door panel 300 may be a fuse-barrel 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 drive lock tab 310, the second drive lock tab 320, and the third drive lock tab 330 may be disposed on top of the first door panel 300. More specifically, the first driving locking plate 310 may be disposed near a first side of the first door panel 300, and the third driving locking plate 330 is disposed near a second side of the first door panel 300 opposite to the first side, so as 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. At this point, the second drive tab 320 is disposed between the first drive tab 310 and the third drive tab 330.

As shown in fig. 2 and 18-19, in some embodiments, the switch cabinet 1 may further include a second door panel 400, and the switch cabinet 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 the fixedly disposed second mounting plate 250, and the second door 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 third pivot pin 251 fixedly provided on the second mounting plate 250.

As shown in fig. 1, 6, 8, 12, 13 and 18-21, in particular, the driven plate 420 may be provided with a third driven portion 421 for cooperating with the second door panel 400, a locking portion 422 for cooperating with the pivoting locking plate 430 and a third actuating portion 426 for cooperating with the interlocking locking plate 220, wherein the second door panel 400 is brought to move the driven plate 420 relative to the second mounting plate 250 by cooperation between the driving portion 410 and the third driven portion 421 of the driven plate 420 when the second door panel 400 is switched between the closed state (corresponding to fig. 1, 6 and 18-19) and the open state (corresponding to fig. 20-21), which is shown to move up and down in the embodiment in the drawings, more particularly, to move up when the second door panel 400 is opened and to move down when the second door panel 400 is closed. In a specific embodiment, as shown in fig. 18 to 21, the third driven portion 421 of the driven plate 420 is a protruding pin fixed on the driven plate 420, and the driving portion 410 of the second door 400 is provided in the form of a protruding piece with a slot 411, wherein the protruding pin can be inserted into the slot 411, so that the second door 400 can drive the driven plate 420 to move relative to the second mounting plate 250 when opening and closing.

In addition, as shown in fig. 7 and 12, the interlocking lock plate 220 may further include a third actuating engagement portion 2261 for engaging with the third actuating portion 426 of the driven plate 420. Specifically, when the ground operating hole is in the ground opening state and the cam 120 is in the stop position, that is, the cam 120 abuts against the first abutting portion 221 of the linkage locking plate 220, so that the linkage locking plate 220 cannot move (cannot move upward in the drawing), at this time, the third actuating engagement portion 2261 of the linkage locking plate 220 blocks the third actuating portion 426 of the driven plate 420 so that the driven plate 420 cannot move (cannot move upward in the drawing), and thus the second door panel 400 can only be kept in the closed state; after the ground engaging operation hole is in the ground engaging state and the cam 120 has been switched from the stop position to the non-stop position, when the second door panel 400 is switched from the closed state to the open state, the driven plate 420 is moved by the driving portion 410 of the second door panel 400 via the third driven portion 421 thereof, while the third actuating portion 426 of the driven plate 420 will abut against the third actuating mating portion 2261 of the interlocking lock plate 220 and apply a driving force thereto, it should be noted that at this time the driven plate 420 is moved relative to the second mounting plate 250, e.g., upwardly, by being driven by the second door panel 400, and therefore the driven plate 420 will be able to drive the interlocking lock plate 220 to be displaced relative to the first mounting plate 250 in the first displacement direction. When the second door panel 400 is in the open state, as described above, the interlocking lock plate 220 is displaced relative to the first mounting plate 230 to a position where the latch engaging portions 223 of the interlocking lock plate 220 will align with the common latch portions 213 of the interlocking plates 210 to block movement of the interlocking plates 210 and thus prevent opening of the cover panel 110 in interlocking with the interlocking plates 210. When the second door panel 400 is switched from the open state to the closed state, the driven plate 420 moves via its third driven portion 421 driven by the driving portion 410 of the second door panel 400, which is shown to move downward, at which time the third actuating portion 426 of the driven plate 420 no longer applies any driving force to the third actuating engagement portion 2261 of the linkage locking plate 220, so that the linkage locking plate 220 may be displaced in a second displacement direction opposite to the first displacement direction if the other door panels are also in the closed state, which is a downward direction in the figure, at which time the linkage locking plate 220 may fall back under its own weight, or be displaced in the second displacement direction under the action of the elastic return member, for example, in other orientation cases. After the second door 400 is closed, if other door panels except the second door 400 are also in a closed state, the ground opening operation may be performed on the ground operation hole such that the cam 120 is switched from the non-stop position to the stop position again.

As shown in fig. 1, 6, 18-21, in some embodiments, the driven plate 420 includes a first driven plate 420a and a second driven plate 420b, the first driven plate 420a includes a third driven portion 421, the second driven plate 420b includes a third actuating portion 426, and the first and second driven plates 420a and 420b are connected to each other by a kidney hole 423 and a screw 424. The waist hole 423 can well compensate the problem of position uncertainty caused by manufacturing and assembling errors and errors caused by component deformation during the operation of the switch cabinet, has strong adaptability, and is beneficial to flexible design.

It should be noted that the urging action of the third urging portion 426 of the driven plate 420 on the third urging engagement portion 2261 of the interlock locking portion 220 occurs when the second door panel 400 is opened only when the other door panels (for example, the first door panel 300) than the second door panel 400 are in the closed state; otherwise, when the other door panel (for example, the first door panel 300) is already in the opened state, the linkage locking plate 220 is already in the second position corresponding to the opened state of the door panel, and the opening of the second door panel 400 does not have any actuation effect on the linkage locking plate 220.

In a specific embodiment, as shown in fig. 6 and 12, the third actuating portion 426 of the driven plate 420 is at least one first protrusion, such as a stud, fixed relative to the driven plate 420, and the third actuating mating portion 2261 of the interlocking lock plate 220 is one end, shown as an upper end, of a corresponding first guide slot 226 provided in the interlocking lock plate 220, each protrusion being insertable into a corresponding first guide slot 226. More specifically, when the second door panel 400 is switched from the closed state to the open state, as described above, the first protrusion as the third actuating portion 426 of the driven plate 420 is inserted into the corresponding first guide groove 226 and applies a driving force to an end (e.g., an upper end) of the first guide groove 226 as the third actuating mating portion 2261 to displace the interlocking lock plate 220 in the first displacement direction with respect to the first mounting plate 230.

More specifically, in the embodiment of the switchgear panel 1 including both the first door panel 300 described above and the second door panel 400 described herein, it may be provided that the at least one first protrusion 426 fixed on the driven plate 420 and the first guide groove 226 provided in the interlocking plate 220 may also cooperate with each other to guide the movement of the interlocking plate 220 with respect to the first mounting plate 230 or the driven plate 420 with respect to the interlocking plate 220. Specifically, the method comprises the following steps:

when the second door panel 400 is in the closed state, when the first door panel 300 is opened or closed, the driven plate 420 remains stationary, and the interlocking lock plate 220 is displaced from the first position to the second position in the first displacement direction or the second displacement direction via the interlocking driven portion 225 thereof by the interlocking driving portion 345 of the first rotation plate 340 included in the first interlocking subassembly of the first interlocking assembly, and the engagement of the first guide groove 226 and the first protrusion 426 inserted into the first guide groove 226 guides the displacement of the interlocking lock plate 220;

when the first door panel 300 is already in the opened state, and when the second door panel 400 is opened or closed, the interlocking lock plate 220 is already in the second position corresponding to the door panel opened state, and the driven plate 420 will move in the first displacement direction or the second displacement direction under the driving of the second door panel 400, but there is no driving effect on the interlocking lock plate 220, and at this time, the cooperation of the first guide groove 226 and the first protrusion 426 inserted into the first guide groove 226 will guide the movement of the driven plate 420.

More specifically, as shown in fig. 6 and 12, a portion of the first mounting plate 230 may be interposed between the interlocking lock plate 220 and the driven plate 420, and the first mounting plate 230 is provided with at least one fifth guide groove 235 (shown in fig. 16) corresponding to the respective first guide groove 226, and the first protrusion 426 may pass through the respective fifth guide groove 235 to be inserted into the respective first guide groove 226. This may ensure a more robust construction. For example, the portion of the first mounting plate 230 may be interposed between the vertical main extension 227 of the linkage locking plate 220 and the second driven plate 420 b.

As shown in fig. 18-21, in some embodiments, the pivoting latch plate 430 is configured to pivot relative to the second mounting plate 250 to an unlocked position and a locked position, respectively, as the second door panel 400 is switched between the closed state and the open state, e.g., the pivoting latch plate 430 is mounted on a third pivot pin 251 fixedly disposed on the second mounting plate 250. Specifically, when the second door panel 400 is switched from the closed state to the open state, the pivoting lock plate 430 will pivot to the locked position, at which time the pivoting lock plate 430 will act as a lock to 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. To this end, the pivoting lock plate 430 may include a mating locking part 432 to be mated with the locking part 422 of the driven plate 420 and a fourth driven part 431 to be mated with the driving part 410 of the second door panel 400. Wherein when the second door panel 400 is in the closed state, the driving portion 410 of the second door panel 400 abuts against the fourth driven portion 431 of the pivot lock plate 430, which causes the pivot lock plate 430 to be held in the unlocked position, as shown in fig. 1, 6 and 18-19, i.e., when the mating lock portion 432 of the pivot lock plate 430 does not have any holding effect on the driven plate 420; when the second door panel 400 is switched from the closed state to the open state, the driving part 410 of the second door panel 400 is gradually disengaged from the fourth driven part 431, this enables the pivoting latch plate 430 to pivot from the unlocked position to the locked position (clockwise in the figures), for example, due to its own weight and/or due to the urging action of the reset member, and thus enables the mating locking portions 432 of the pivotal lock plate 430 to abut and hold the locking portions 422, to thereby lock the driven plate 420, i.e., when the second door panel 400 has been in the open state, the engagement between the engagement locking portions 432 of the pivoting lock panel 430 and the locking portions 422 of the driven panel 420 holds the driven panel 420 stationary, for example, in the embodiment shown in the drawings, the mating latching portions 432 of the pivoting-latch plate 430 at this time hold the lower ends of the latching portions 422 of the driven plate 420 to apply upward supporting force to the driven plate 420, as shown in fig. 20 to 21; when the second door panel 400 is switched from the open state to the closed state, the driving portion 410 of the second door panel 400 contacts and pushes against the fourth driven portion 431 of the pivotal lock plate 430 again, and thus drives the pivotal lock plate 430 to pivot from the locked position back to the unlocked position (in the counterclockwise direction in the drawing), so that the mating locking portions 432 of the pivotal lock plate 430 release the locking portions 422 of the driven portion 420, and thus release the holding of the driven plate 420.

As shown in fig. 18-21, in a more specific embodiment, to facilitate the return of the pivot lock plate 430 from the unlocked position to the locked position, the second linkage assembly further includes a fifth resilient member 440, such as a tension spring, 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 fifth 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 fifth 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. 19-21, in some embodiments, the driven plate 420 is provided with at least one sixth guide slot 427, the second mounting plate 250 is correspondingly provided with at least one sixth guide tab 257, and the sixth guide slot 427 cooperates with the sixth guide tab 257 to guide movement of the driven plate 420 relative to the second mounting plate 250. In an alternative not shown, the driven plate 420 may be provided with at least one sixth guide protrusion, and the second mounting plate 250 may be correspondingly provided with at least one sixth guide groove.

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 can only 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.
